  1. Configurations of Huaweiand NSN eNBs

  2. Outline • Setup and Parameters for Huawei/NSN eNBs - Management Tools of eNBs - Log Tracing Tool - Key Parameters Setting

  3. Management Tools of eNBs • Huawei eNB LMT (Local Mantenance Terminal) • NSN eNB BTS Site Manager

  4. Huawei eNB LMT(Local Maintenance Terminal) • The eNBLMT deploys the eNBand identifies and clears faults. • Use the LMT to operate and maintain the Huawei eNB

  5. Huawei LMT Alarm/Event: eNB status • Showing faults of eNBs in the following level • Critical alarm: : requires immediate actions even during non-working hours. • Major alarm: requires immediate action during working hours. • Minor alarm: generally does not affect service quality • Warning alarm: indicates a potential error

  6. Huawei LMT Alarm/Event Example: “SCTP Link Fault” • Main reason of control plane failure • Possible causes - A failure link between EPC and eNB - Failure links to the peer devices - SCTP is blocked - Inconsistent parameters with peer devices - The peer device is faulty

  7. Huawei eNBPower setting(TDD) • MOD PDSCHCFG-> reference signal power • RSpwr:152 -> max txpwr ->43dBm DSP CELL DSP PDSCHCFG MOD PDSCHCFG

  8. NSN eNBBTS Site Manager • The BTS Site Manager deploys the eNBand identifies and clears faults. • Use the Site Manager to operate and maintain the NSN eNB

  9. Log Tracing Tool • Huawei LMT Log tracing tool - 18 tracing tasks can be simultaneously created on an LMT client - Message tracing management traces interfaces, signaling links, and UEs No tracing tools in NSN eNBs

  10. Huawei LMT Log Tracing • Tracing tool located at eNB • Tracing messages over the S1 interface • Tracing messages over the X2 interface • Tracing messages over the Uu interface • Tracing SCTP messages

  11. Huawei LMT Log Tracing: Successful SCTP Establishment

  12. Key Parameters Setting • Key parameters that effect performance of throughput most -Subframe/Special Subframe Patterns -Transmission Mode Configuration -MCS, Modulation and Coding Scheme

  13. Huawei LMT MML • Maintain and manage configuration of eNB • Two interfaces of MML - GUI - Command line

  14. Huawei MML: Transmission Mode Config • --TXDiv(TM2) • --Static Open Loop SM (TM3) • --Closed Loop SM (TM4) • --Single Stream Beamforming(TM7) • --Dual Stream Beamforming(TM8) • --TxD BF ADAPTIVE • --MIMO BF ADAPTIVE

  15. Huawei TM ConfigExample “TM3” • MOD BFMIMOADAPTIVEPARACFG: BfMimoAdaptiveSwitch=NO_ADAPTIVE, FixedBfMimoMode=TM3;

  16. NSN TM Config Example “TM3” • Only GUI, no command line --TXDiv(TM2) --Static Open Loop SM (TM3) --Closed Loop SM (TM4) --Single Stream Beamforming(TM7) --Dynamic Open Loop (NSN)

  17. Summary NSN vs. Huawei Key Parameters -Subframe/Special Subframe Patterns -> NSN: SA 1-2, SSP 5-7 -> Huawei: SA 0-6, SSP 0-7 -Transmission Mode Configuration -> NSN: TM2, TM3, TM4, TM7, Dynamic Open Loop -> Huawei: TM2, TM3, TM4, TM7, TM8, “TxDBF ADAPTIVE”, “MIMO BF ADAPTIVE” -MCS, Modulation and Coding Scheme -> NSN DL: 64 QAM16QAM BPSK -> Huawei DL: 64 QAM

  18. Summary NSN vs. Huawei Management Tool -Log tracing -> NSN: N/A -> Huawei: Yes -Parameter setting -> NSN: GUI -> Huawei: GUI, Command line
