New Features1. GSM and UMTS Dynamic Power Sharing

Description This feature enables power to be shared betweenthe GSM TRX and the UMTS TRX to improve theutilization of power resources.

Improvement This feature improves the network performanceand PA power utilization.As more power resources can be used for dataservices, the average throughput and edgethroughput of UMTS cells are increased. Thesimulation test result in the lab suggests thatthe average cell throughput is increased by 10%.

Implementation

The average output power of a GSM TRX is lowerthan the maximum output power due to powercontrol, discontinuous transmission (DTX), andgrade of service (GoS). By using the multi-TRXtechnology and SDR technology, the UMTS TRX canshare the GSM TRX power under the same PA. Thisfunction increases the utilization of the PA andthe HSPA service rate of the UMTS cell.In the case of a GSM service burst, the GSM TRXpower shared by the UMTS TRX can be reclaimed inthe sharing period.

RelatedOperation

2. Fault management enhancement-alarm filter allowed

Description This feature enhances the fault managementfunction. An alarm is reported only once duringa period of time, instead of reportedrepeatedly. In this way, the number of reportedalarms is reduced.

Improvement This feature significantly reduces the number ofredundant alarms and therefore prevents theunnecessary work on such alarms by maintenancepersonnel. In a word, the OPEX is reduced.

Implementation

An alarm is reported when the accumulated alarmpersistence duration in the RTW parameter (AlarmRaise Time Window) reaches the value of the RTHparameter (Alarm Raise Time Threshold); an alarmis cleared when the accumulated alarmpersistence duration in the CTW parameter (AlarmCease Time Window) is smaller than the value ofthe CTH parameter (Alarm Cease Time Threshold).

RelatedOperation

Run the SET ALMFILTER command to set the alarmfilter parameter.

Modified Features

1. 2×2 MIMO

Description The primary and secondary pilot networkingmodes of the MIMO cell are supported since thisversion. From this version, the Virtual AntennaMapping(VAM) function is supported.

Improvement When the cell is configured in STTD mode, HSDPAservices are adversely affected. Therefore, MIMOand HSDPA cannot co-exist in one cell. The problemcan be resolved by adopting the primary andsecondary pilot networking modes, and the VAMfunction enables balance of output power betweentwo Power Amplifiers (PAs).

Implementation

In the primary and secondary pilot network, thesecondary pilot dynamic switch is implemented toreduce the interference of the secondary pilot onthe R99 and HSDPA services. In this way, the TX ofthe secondary pilot is automatically disabled whenthere are no MIMO users in the cell andautomatically enabled when there are MIMO users inthe cell.The main and diversity signals output by thebaseband are mapped to the two PAs respectively byusing the virtual orthogonal matrix switch mode.In this way, each PA has the main and diversitysignals, thus achieving balance in output power ofthe two PAs. In addition, an alpha multiplyingfactor is introduced to the baseband diversityoutput. The alpha factor can be timely adjustedaccording to the live-network user distribution.Therefore, the interference of MIMO users on HSDPAusers can be reduced.

RelatedOperation

2. Scheduling based on EPF and GBR is optimized.

Description GBR services of 1 Mbit/s or higher data ratesare guaranteed, if sufficient radio resourcesand Iub-interface resources are available.

Improvement UEs can use the GBR services of 1 Mbit/s orhigher data rates.

Implementation

In scheduling for HSDPA services, resources arepreferentially allocated to UEs whose the GBRrequirements are not met, rather than UEs thathave no GBR requirements or UEs whose GBRrequirements are already met.

RelatedOperation

No more operations compared with the relatedoperations of the feature Scheduling based onEPF and GBR.

3. Performance counters related to HSPA flow control are addedfor evaluation of the HSPA flow control algorithm.

Description Performance counters related to the HSPA flowcontrol algorithm are added to the NodeB. Theyare used to evaluate the HSPA flow controlalgorithm.

Improvement After the performance counters related to flowcontrol are added, the HSPA flow controlalgorithm can be better evaluated.Note: For the NodeB of the current version,performance counters related to flow control aredefined on the northbound interface. Theseperformance counters are reported in later NodeBversions. The purpose is to prevent modificationon the northbound interface and upgrade inmediation software in later NodeB versions.

Implementation

Performance counters related to flow control areadded.

RelatedOperation

3.9 Changes from V200R011C00SPC110 to V200R012C003.9.1 Feature Changes

New Features1. Single IP address for the NodeB




Description The IP addresses of the NodeB consist of thecontrol plane IP address, user plane IP address,and NodeB OM IP address. Currently, typicalapplication is that the control plane IP addressand user plane IP address are configured to usethe same port IP address. The OM IP address anduser plane IP address should be assigned withtwo different IP addresses belonging todifferent IP subnets. Therefore, operators needto plan two sets of IP addresses and routingrules during network deployment. With theintroduction of single IP address for the NodeB,the traffic channel and OM channel are enabledto share one IP address.

Improvement With the introduction of single IP address forthe NodeB, the traffic channel and OM channelare enabled to share one IP address. In thisway, more IP address resources are saved and IProute configuration is simplified when IPtransport is adopted.

Implementation

When a BTS3900/BTS3900A/DBS3900 is configuredwith one WMPT and the WMPT provides one or moreIP ports, the OM IP address can be the same asone of the port IP addresses. When usingredundancy configuration for OM channels, thetwo OM IP addresses can be the same as those ofthe two ports provided by the WMPT.When a BTS3900/BTS3900A/DBS3900 is configuredwith one WMPT and multiple UTRPs and the WMPT orUTRP provides one or more IP ports, the OM IPaddress of the NodeB can be the same as one ofthe port IP addresses. When using redundancyconfiguration for OM channels, the two OM IPaddresses can be the same as those of the two IPports provided by the WMPT. The two OM IPaddresses are not allowed to be the same asthose of two IP ports provided by the UTRP.A BTS3900/BTS3900A/DBS3900 is configured withmultiple ports (E1/T1/Ethernet), and the portscan be combined as one IP interface throughEthernet Trunk and MLPPP. If the IP port islocated on the WMPT, the OM IP address can bethe same as that of the combined IP port.

Related The ADD DEVIP command is used to configure the



Operation same IP address for the service channel and OMchannel.

2. Management and monitoring of the solar equipment

Description The solar power system supplies the powerproduced by solar array to the load. The surpluspower is stored in the batteries. The solarpower system runs under the control of the solarcontroller.

Improvement This feature improves the operability andmaintainability of the NodeB and solarequipment, which enables a much greener NodeB.

Implementation

The solar controller, like the traditional powermonitoring device, is managed as the PMU. Theconfiguration, maintenance, and statusmonitoring of the solar controller are performedthrough the 485 serial port by the NodeB.

RelatedOperation

The ADD PMU command is used to add the solarcontroller to the NodeB configurations. Thecommands for the PMU are used to configure andmaintain the solar controller.






3. HSUPA Uplink Interference Cancellation



Description HSUPA UL Interference Cancellation (IC) isperformed to cancel the interference caused bythe UL high rate EDPDCH data to improve thedemodulation signal-to-noise ratio (SNR) andthus to increase the UL system capacity of thenetwork.

Improvement The introduction of the IC technologysignificantly improves the UL capacity of theUMTS. In certain scenarios, the gain of the ICtechnology is significant. For example, if thesystem needs to support a small number of HSUPAusers with high throughput and a large number ofHSUPA users with low throughput, the IC isrequired to cancel the uplink interferencebrought by HSUPA users with high throughput.Without the IC technology, the high ULinterference may be generated from the highspeed HSUPA users. In such a case, if the rateof the original high rate HSUPA users must beguaranteed, the number of low speed users, forexample, VoIP users must be limited. Otherwise,the original high speed HSUPA users may beaffected, the speed of services may decrease tothe minimum.

Implementation

The IC technology supports different categoriesof HSUPA users, including UEs of categories 1 to7. The principle of the IC technology is thatthe receiver of the NodeB demodulates the HSUPAdata on the UL EDPDCH and reconstructs thebaseband data based on the demodulated data andreceived baseband data. The NodeB thendemodulates the reconstructed baseband data. Forthe reconstructed baseband data, theinterference from the reconstructed EDPDCH datais eliminated and the colored noise in the cellcaused by the self-interference feature of theUMTS is reduced. Therefore, the SNR of thereconstructed data is improved.

RelatedOperation

Use the MOD LOCELL command to set a local cellto support the IC function.






4. HSUPA Uplink Frequency Domain Balancing

Description With the HSUPA uplink frequency domain balancingfeature, the NodeB uplink receiver balances thespectrum in the frequency domain of the HSUPA E-DPDCH and reduces the inter-path interference ofthe E-DPDCH. In this way, the

Improvement The uplink inter-path interference of HSUPAusers is reduced, thus helping to enhance ahigher peak data rate for HSUPA users.

Implementation

The NodeB uplink receiver balances the spectrumin the frequency domain of the HSUPA E-DPDCH andreduces the inter-path interference of the E-DPDCH.

RelatedOperation

Use the MOD LOCELL command to set a local cellto support the frequency domain balancingfunction.





5. Downlink 64QAM and MIMO

Description The MIMO and 64QAM are introduced in 3GPP R7.These two features can be used separately. Asingle user, however, is not allowed to usethese two features at the same time. In 3GPP R8,a single user is allowed to use MIMO and 64QAMtogether, which provides higher peak data rate.

Improvement The peak rate of a single user can be increasedfrom 28 Mbit/s (MIMO+16QAM) or 21 Mbit/s (64QAM)to 42 Mbit/s.There is no terminal for commercial use atpresent. The IOT and other related tests are notconducted. This feature is optimized in laterversions.

Implementation

The extension CQI table is added for MIMO and64QAM users, and the scheduling of MIMO and64QAM users is supported.

RelatedOperation

Use the MOD LOCELL command to set a local cellto support the 64QAM and MIMO functions.






6. Uplink 16QAM

Description The UE category 7 is introduced in 3GPP R7. TheUE of this category supports 16QAM and reaches11.5 Mbit/s in the uplink.

Improvement The uplink system capacity of the HSUPA networkis improved, and HSUPA users (UE category 7)reach higher peak data rate.

Implementation

The processing of the E-DCH using 16QAM at thephysical layer is supported, and scheduling ofUE category 7 is supported.There is no terminal for commercial use atpresent. The IOT and other related tests are notconducted. This feature is optimized in laterversions.

RelatedOperation

Use the MOD LOCELL command to set a local cellto support the uplink 16QAM function.





7. Uplink Layer 2 Enhancement

Description With the introduction of the uplink layer 2enhancement, the uplink RLC supports flexiblePDU and the MAC-i/is entity is introduced in theMAC layer. The main difference between the MAC-i/is and the MAC-es/s is that the formersupports data segmentation and reassembling. TheMAC-is/i can choose a suitable PDU on the basisof air interface quality, thus improving datatransmission efficiency.

Improvement The peak data rate of a single user isincreased, and the uplink throughput of theweak-coverage cell is improved.There is no terminal for commercial use atpresent. The IOT and other related tests are notconducted. This feature is optimized in laterversions.

Implementation

The MAC-i/is entity is introduced in the uplinklayer 2 enhancement and the NodeB implements thefunctions of the MAC-I entity.

RelatedOperation

Use the MOD LOCELL command to set a local cellto support the uplink layer 2 enhancementfunction.






8. DC-HSDPA

Description The Dual Cell-HSDPA (DC-HSDPA) feature enablesthe UE to set up connections in two downlinkinter-frequency cells with the same coverage. Inthis way, the UE can use cell resources of twodifferent carriers, thus increasing the peakthroughput of the UE.

Improvement 1. The throughput of a single user is improved.Compared to the networking where the DC-HSDPA isnot introduced, a maximum of two timesthroughput can be provided at the cell centerand edges.2. The cell throughput is improved. Compared tothe total throughput of two inter-frequencycells with the same coverage in the scenariowhere the DC-HSDPA is not introduced, the DC-HSDPA improves the cell throughput by 5% to 10%.The throughput improvement is related to thenumber of users in the cells. If the number ofusers increases, the cell throughput decreases. There is no terminal for commercial use atpresent. The IOT and other related tests are notconducted. This feature is optimized in laterversions.

Implementation

The users are allowed to configure a DC localcell group through MML commands. The two cellsin the DC local cell group report the DCcapability to the RNC. The scheduling of DC-HSDPA users is supported, and the handling ofthe DC-HSDPA and HS-DPCCH is also supported.

RelatedOperation

Use the ADD DUALCELLGRP command to set the DClocal cell group. The two cells in the DC localcell group should support the DC function.Use the RMV DUALCELLGRP command to remove aspecified DC local cell group.Use the LST DUALCELLGRP command to query all theconfigured DC local cell groups.Use the MOD LOCELL command to set a local cellto support the DC function.





9. Improvement of Small-Traffic Service Delay Experience

Description The services with small traffic (such as HTTP orGaming) are distinguished from all the servicescarried by the HSPA channels. More resources areallocated to such services with small traffic,thus enhancing the delay experience.

Improvement Users can obtain better delay experience whenusing bursty small-traffic services.

Implementation

The bursty data packet size is set according tothe user priority. For services whose total dataamount does not exceed the defined value areidentified as small-traffic services. Theresources are preferentially allocated to small-traffic services in HSPA scheduling and flowcontrol, thus optimizing the delay.

RelatedOperation

Use the SET UEQOSENHANCEPARA command to set thebursty data packet size for users of differentpriorities.Use the LST UEQOSENHANCEPARA command to querythe bursty data packet size.






10. 2 x 2 MIMO

Description 2 x 2 Multiple Input Multiple Output (MIMO) uses two transmit antennas at the NodeB to transmit orthogonal (parallel) data streams tothe two receive antennas at the UEs.

Improvement Using two antennas and additional signal processing at the receiver and the transmitter, 2 x 2 MIMO can increase the system capacity and double user data rates without using additional bandwidth. 2 x 2 MIMOadopts different modes in the 3GPP protocols, with QPSK and 16QAM in R7, and later with 64QAM in R8. With dual-stream dual-antenna mode and16QAM modulation, the peak data rate per user is doubled to 28 Mbit/s and also the average throughput of the system is enhanced.

Implementation

The 3GPP R7 protocols define the categories ofthe UEs that support MIMO, and add the information elements (IEs) that support MIMO in the reporting of local cell capability. TheRNC determines whether the RL between the NodeB and the UE supports MIMO according to the local cell capability and UE capability reported by the NodeB. If the RL supports MIMO, the MAC-hs scheduler of the NodeB determines every 2 ms whether to use MIMO according to the following aspects: Channel Quality Indicator (CQI) reported by the UE

Precoding Control Indication (PCI) HS-PDSCH code resources and power resources of the NodeB

Related Operation

This function is controlled through a license.The function is available only when the operator purchases the license from Huawei.





11. HSUPA Adaptive Retransmission

Description With comprehensive considerations of cell uplink power load, CE resources, and limited uplink coverage, this feature enables the adaptive adjustment of the number of target uplink retransmissions to improve the throughput per user and cell uplink capacity.

Improvement In a limited uplink coverage scenario, a user’s uplink cell edge throughput can be increased, in order to enhance user experience. According to simulation results, single user throughput has been show to increase by 15%-60%.

In a scenario where the cell uplink power load is limited, increasing the retransmission number can improve cell throughput and cell uplink capacity. Simulation results have shown an increase of 53% in cell throughput under multi-user scenarios.

Implementation

This feature is only effective in BE traffic. If a user, only has BE traffic (with the exception of SRB) on E-DCH, then dynamic adjustment of the target retransmission numberis allowed. Adjusting the users target retransmission number to a relatively smaller value is permitted when the uplink power of all the cells belonging to the serving RLS is smaller than a certain threshold and the UE uplink power is not limited and/or uplink CEs are limited. When the uplink power of any cellbelonging to the serving RLS experiences congestion or UE’s uplink power is limited, then setting the users target retransmission number to a relatively higher value is permitted, as long as the uplink CE resources are sufficient.

Related Operation

This function can be enabled or disabled by SET ADPRETRANSSWTCH, and query the switch status by LST ADPRETRANSSWTCH.

2. NodeB software management

Description The OM channel carries high-priority servicessuch as MML command operations and transmissionof clock synchronization messages, as well aslow-priority services such as file uploading anddownloading of background services. The OMmessages of different priorities identifydifferent DSCP values and VLAN COS priorities.This avoids low-priority services occupyinglarge service bandwidth and impact on the high-priority OM messages and services and ensurespriority guarantee in end-to-end transmission.

Improvement The OM messages are differentiated bypriorities. That is, messages of differentpriorities identify different DSCP values andVLAN COS priorities. This ensures priorityguarantee in end-to-end transmission in L2Ethernet or L3 IP route networking.

Implementation

The OM messages of different priorities areconfigured with the corresponding DSCP and VLANCOS fields. This ensures that OM messages ofhigh priority take the precedence intransmission. In addition, in the case oflimited bandwidth, OM messages of low prioritydo not affect the provision of messages andservices of high priority.

RelatedOperation

The SET DIFPRI command is used to set thecorresponding DSCP values for the OM messages ofdifferent priorities.The SET VLANCLASS command is used to set thecorresponding VLAN COS values for the OMmessages of different priorities.






3. Intelligent shutdown

Description If the mains for the NodeB with the power backupsystem fails, intelligent shutdown of the cell,RF module, and NodeB can be enabled. Theintelligent shutdown is implemented throughpowering off the cell, RF module, and the entireNodeB level by level. Users can set different DCvoltage thresholds and NodeB and cell shutdownpriorities. The intelligent shutdown of theNodeB and RF module is supported from RAN5.0.The intelligent shutdown of cells is availablefrom this version.

Improvement The intelligent shutdown function saves theinvestment for battery backup system and meetscustomers’ requirements for energy saving andpower consumption. The function is particularlybeneficial to the NodeB which is a transmissioncenter node. In this case, separate power backupsystems for the NodeB and transmission equipmentare not required. Longer duration of powersupply is implemented through setting differentshutdown thresholds.

Implementation

The NodeB supports setting priorities forshutting down cells. The cells are shut down inturn according to their priorities, thusextending power supply duration. After the mainspower of the NodeB is shut down, batteries startsupplying power. When the battery voltagedecreases to a certain threshold, the NodeBenables the intelligent shutdown of cells toshut down the TRX of non-reserved cells. If thebattery voltage keeps decreasing to anotherthreshold, the NodeB shuts down the TRX of allthe cells.

4. NodeB self-discovery

Description In IP mode, Huawei NodeBs have two types ofautomatic address identification: DHCP andDHCP+AACP. In practical usage, the RAN systemenables different automatic addressidentification types for different scenarios.The DHCP+AACP type is the enhancement of theNodeB automatic address identification feature.The difference between DHCP and DHCP+AACP isthat: In DHCP+AACP mode, one NodeB provides DHCPrelay functions for other NodeBs; in DHCP mode,the transmission device in the RAN is requiredto provide DHCP relay functions for the NodeB.For the IP RAN, not all the networks can providethe network devices with the relay functions.Therefore, the Huawei RAN system introducesDHCP+AACP for such networks.DHCP+AACP is applicable to only the Ethernettransmission.

Improvement The automatic address identification of theNodeB is implemented when the network devices donot support the DHCP relay functions.

Implementation

When the network devices do not support the DHCPrelay function, Huawei RAN system remotelyassigns a temporary IP address to a NodeB in thenetwork through the AACP server and sends theAACP detection packet to the subnet of theNodeB. Then, one of the NodeBs obtains the AACPdetection packet through the ARP mechanism. Thetemporary IP address is used to communicate withthe DHCP server to obtain a formal IP addressfor the NodeB. When the formal IP address isset, the NodeB can be configured as the DHCPrelay of this sub-network, thus helping otherNodeBs in the sub-network to perform automaticidentification through the DHCP mechanism.

Additional configuration of the NodeB is notrequired for this feature.

3.10 Changes from V200R010C01SPC300 to V200R012C003.10.1 Feature Changes

New Features1. Single IP address for the NodeB



Description The IP addresses of the NodeB consist of thecontrol plane IP address, user plane IP address,and NodeB OM IP address. Currently, typicalapplication is that the control plane IP addressand user plane IP address are configured to usethe same port IP address. The OM IP address anduser plane IP address should be assigned withtwo different IP addresses belonging todifferent IP subnets. Therefore, operators needto plan two sets of IP addresses and routingrules during network deployment. With theintroduction of single IP address for the NodeB,the traffic channel and OM channel are enabledto share one IP address.

Improvement With the introduction of single IP address forthe NodeB, the traffic channel and OM channelare enabled to share one IP address. In thisway, more IP address resources are saved and IProute configuration is simplified when IPtransport is adopted.

Implementation

When a BTS3900/BTS3900A/DBS3900 is configuredwith one WMPT and the WMPT provides one or moreIP ports, the OM IP address can be the same asone of the port IP addresses. When usingredundancy configuration for OM channels, thetwo OM IP addresses can be the same as those ofthe two ports provided by the WMPT.When a BTS3900/BTS3900A/DBS3900 is configuredwith one WMPT and multiple UTRPs and the WMPT orUTRP provides one or more IP ports, the OM IPaddress of the NodeB can be the same as one ofthe port IP addresses. When using redundancyconfiguration for OM channels, the two OM IPaddresses can be the same as those of the two IPports provided by the WMPT. The two OM IPaddresses are not allowed to be the same asthose of two IP ports provided by the UTRP.A BTS3900/BTS3900A/DBS3900 is configured withmultiple ports (E1/T1/Ethernet), and the portscan be combined as one IP interface throughEthernet Trunk and MLPPP. If the IP port islocated on the WMPT, the OM IP address can bethe same as that of the combined IP port.

3. HSUPA Uplink Interference Cancellation




Description HSUPA UL Interference Cancellation (IC) isperformed to cancel the interference caused bythe UL high rate EDPDCH data to improve thedemodulation signal-to-noise ratio (SNR) andthus to increase the UL system capacity of thenetwork.

Improvement The introduction of the IC technologysignificantly improves the UL capacity of theUMTS. In certain scenarios, the gain of the ICtechnology is significant. For example, if thesystem needs to support a small number of HSUPAusers with high throughput and a large number ofHSUPA users with low throughput, the IC isrequired to cancel the uplink interferencebrought by HSUPA users with high throughput.Without the IC technology, the high ULinterference may be generated from the highspeed HSUPA users. In such a case, if the rateof the original high rate HSUPA users must beguaranteed, the number of low speed users, forexample, VoIP users must be limited. Otherwise,the original high speed HSUPA users may beaffected, the speed of services may decrease tothe minimum

Implementation

The IC technology supports different categoriesof HSUPA users, including UEs of categories 1 to7. The principle of the IC technology is thatthe receiver of the NodeB demodulates the HSUPAdata on the UL EDPDCH and reconstructs thebaseband data based on the demodulated data andreceived baseband data. The NodeB thendemodulates the reconstructed baseband data. Forthe reconstructed baseband data, theinterference from the reconstructed EDPDCH datais eliminated and the colored noise in the cellcaused by the self-interference feature of theUMTS is reduced. Therefore, the SNR of thereconstructed data is improved.

Description With the introduction of the uplink layer 2enhancement, the uplink RLC supports flexiblePDU and the MAC-i/is entity is introduced in theMAC layer. The main difference between the MAC-i/is and the MAC-es/s is that the formersupports data segmentation and reassembling. TheMAC-is/i can choose a suitable PDU on the basisof air interface quality, thus improving datatransmission efficiency.

Improvement The peak data rate of a single user isincreased, and the uplink throughput of theweak-coverage cell is improved.There is no terminal for commercial use atpresent. The IOT and other related tests are notconducted. This feature is optimized in laterversions.

Improvement 1. The throughput of a single user is improved.Compared to the networking where the DC-HSDPA isnot introduced, a maximum of two timesthroughput can be provided at the cell centerand edges.2. The cell throughput is improved. Compared tothe total throughput of two inter-frequencycells with the same coverage in the scenariowhere the DC-HSDPA is not introduced, the DC-HSDPA improves the cell throughput by 5% to 10%.The throughput improvement is related to thenumber of users in the cells. If the number ofusers increases, the cell throughput decreases. There is no terminal for commercial use atpresent. The IOT and other related tests are notconducted. This feature is optimized in laterversions.

10. 2 × 2 MIMO

Description 2 x 2 Multiple Input Multiple Output (MIMO) uses two transmit antennas at the NodeB to transmit orthogonal (parallel) data streams tothe two receive antennas at the UEs.

Improvement Using two antennas and additional signal processing at the receiver and the transmitter, 2 x 2 MIMO can increase the system capacity and double user data rates without using additional bandwidth. 2 x 2 MIMOadopts different modes in the 3GPP protocols, with QPSK and 16QAM in R7, and later with 64QAM in R8. With dual-stream dual-antenna mode and16QAM modulation, the peak data rate per user is doubled to 28 Mbit/s and also the average throughput of the system is enhanced.

Implementation

The 3GPP R7 protocols define the categories ofthe UEs that support MIMO, and add the information elements (IEs) that support MIMO in the reporting of local cell capability. TheRNC determines whether the RL between the NodeB and the UE supports MIMO according to the local cell capability and UE capability reported by the NodeB. If the RL supports MIMO, the MAC-hs scheduler of the NodeB determines every 2 ms whether to use MIMO according to the following aspects: Channel Quality Indicator (CQI) reported by the UE

11. HSUPA Adaptive Retransmission

Description With comprehensive considerations of cell uplink power load, CE resources, and limited uplink coverage, this feature enables the adaptive adjustment of the number of target uplink retransmissions to improve the throughput per user and cell uplink capacity.

Improvement In a limited uplink coverage scenario, a user’s uplink cell edge throughput can be increased, in order to enhance user experience. According to simulation results, single user throughput has been show to increase by 15%-60%.

In a scenario where the cell uplink power load is limited, increasing the retransmission number can improve cell throughput and cell uplink capacity. Simulation results have shown an increase of 53% in cell throughput under multi-user scenarios.

Implementation

This feature is only effective in BE traffic. If a user only has BE traffic (with the exception of SRB) on E-DCH, then dynamic adjustment of the target retransmission numberis allowed. Adjusting the users target retransmission number to a relatively smaller value is permitted when the uplink power of all the cells belonging to the serving RLS is smaller than a certain threshold and the UE uplink power is not limited and/or uplink CEs are limited. When the uplink power of any cellbelonging to the serving RLS experiences congestion or UE’s uplink power is limited, then setting the users target retransmission number to a relatively higher value is permitted, as long as the uplink CE resources are sufficient.

2. NodeB software management

Description The OM channel carries high-priority servicessuch as MML command operations and transmissionof clock synchronization messages, as well aslow-priority services such as file uploading anddownloading of background services. The OMmessages of different priorities identifydifferent DSCP values and VLAN COS priorities.This avoids low-priority services occupyinglarge service bandwidth and impact on the high-priority OM messages and services and ensurespriority guarantee in end-to-end transmission.

Improvement The OM messages are differentiated bypriorities. That is, messages of differentpriorities identify different DSCP values andVLAN COS priorities. This ensures priorityguarantee in end-to-end transmission in L2Ethernet or L3 IP route networking.

Implementation

The OM messages of different priorities areconfigured with the corresponding DSCP and VLANCOS fields. This ensures that OM messages ofhigh priority take the precedence intransmission. In addition, in the case oflimited bandwidth, OM messages of low prioritydo not affect the provision of messages andservices of high priority.

RelatedOperation

Theintelligent shutdown is implemented throughpowering off the cell, RF module, and the entireNodeB level by level. Users can set different DCvoltage thresholds and NodeB and cell shutdownpriorities. The intelligent shutdown of theNodeB and RF module is supported from RAN5.0.The intelligent shutdown of cells is availablefrom this version.

Improvement The intelligent shutdown function saves theinvestment for battery backup system and meetscustomers’ requirements for energy saving andpower consumption. The function is particularlybeneficial to the NodeB which is a transmissioncenter node. In this case, separate power backupsystems for the NodeB and transmission equipmentare not required. Longer duration of powersupply is implemented through setting differentshutdown thresholds.

Implementation

The NodeB supports setting priorities forshutting down cells. The cells are shut down inturn according to their priorities, thusextending power supply duration. After the mainspower of the NodeB is shut down, batteries startsupplying power. When the battery voltagedecreases to a certain threshold, the NodeBenables the intelligent shutdown of cells toshut down the TRX of non-reserved cells. If thebattery voltage keeps decreasing to anotherthreshold, the NodeB shuts down the TRX of allthe cells. If the battery voltage resumes to acertain threshold, the NodeB automatically openup all the cells whose TRX was shut down.

4. NodeB self-discovery

Description In IP mode, Huawei NodeBs have two types ofautomatic address identification: DHCP andDHCP+AACP. In practical usage, the RAN systemenables different automatic addressidentification types for different scenarios.The DHCP+AACP type is the enhancement of theNodeB automatic address identification feature.The difference between DHCP and DHCP+AACP isthat: In DHCP+AACP mode, one NodeB provides DHCPrelay functions for other NodeBs; in DHCP mode,the transmission device in the RAN is requiredto provide DHCP relay functions for the NodeB.For the IP RAN, not all the networks can providethe network devices with the relay functions.Therefore, the Huawei RAN system introducesDHCP+AACP for such networks.DHCP+AACP is applicable to only the Ethernettransmission.

Improvement The automatic address identification of theNodeB is implemented when the network devices donot support the DHCP relay functions.

Implementation

When the network devices do not support the DHCPrelay function, Huawei RAN system remotelyassigns a temporary IP address to a NodeB in thenetwork through the AACP server and sends theAACP detection packet to the subnet of theNodeB. Then, one of the NodeBs obtains the AACPdetection packet through the ARP mechanism. Thetemporary IP address is used to communicate withthe DHCP server to obtain a formal IP addressfor the NodeB.

6. Link Aggregation

Description The FE/GE interface board (UTRP2, UTRP9) is added from this issue. The Link aggregation enables teaming of two FE/GE ports which are onthe same board. In this way, the two teamed FE/GE ports are regarded as one port in transmitting and receiving data.

Improvement The teaming of two FE/GE ports can improve the reliability: The trunk group which has all its links teamed can keep working properly in the case of a faulty FE/GE port. Moreover, the bandwidth can increase: The bandwidth of the trunk group which has all its links teamed is two times the bandwidth of the original FE/GE ports.

Implementation

To allow teaming of two FE/GE ports on the sameboard, ensure that the two FE/GE ports are consistent in bandwidth as well as in mode (teaming of one FE/GE optical port and one FE/GE electrical port not allowed). The load sharing among links during data transmission are implemented based on the quaternion.

9. Uplink Macro Diversity Intelligent Receiving

Description The macro diversity has a small gain for the high speed non-real-time services and occupies much transmission bandwidth on the Iub interface. Therefore, the Uplink Macro Diversity Intelligent Receiving is introduced in R7 protocol. For the non-service links, the MAC-d flow of the service can be provided with an option of not establishing the transmission bearing.

Improvement The transmission bandwidth resources on the Iub interface are saved.

The resource usage is improved. The performance of the network is optimized.

22. Clock Synchronization on Ethernet in NodeB

Description The NodeB supports clock synchronization basedon the 1588v2 protocol. The clock accuracy of this synchronization mode meets the requirements of the NodeB. At present, the NodeB supports the OC function. That is, the clock is obtained from the lines rather than provided for downstream equipment through the lines.

Improvement The clock is obtained based on the 1588v2 protocol, without the help of an external GPS clock, which reduces network construction cost.The 1588v2 is a standard protocol, which can be supported by network equipment through upgrade in future. In this case, operators arerequired to have only the clock server insteadof installing new equipment.

Implementation

For the clock synchronization based on the 1588v2 protocol, the clock server regularly sends clock synchronization messages to the NodeB. After receiving the messages, the NodeBperforms actions such as de-jitter. Then, the clock is locked and acts as the reference clock source of the NodeB.

Related Operation

Run the ADD IPCLKLNK command to add clock links. Run the SET CLKMODE command to set the reference clock source of the NodeB.
