Advanced MPR Requirements for NS_52 in 3GPP RAN4 Meeting
Explore the discussion on A-MPR requirements for NS_52 channels in the 3GPP TSG-RAN WG4#96-e meeting. Topics include A-MPR values, tentative agreements, and recommendations for PSSCH_PSCCH and PFSCH for NR V2X UE. Detailed tables and A-MPR levels are proposed for further rounds of work. Dive into the background, WF on PSSCH_PSCCH A-MPR for PC3 NR V2X UE, and definition of regions for PSSCH_PSCCH NS_52 A-MPR.

3GPP TSG-RAN WG4#96-e Meeting R4-2011704 Electronic Meeting, 17th August 28th August, 2020 WF on A-MPR requirements for NS_52 Qualcomm, LG Electronics...
Background In this meeting, RAN4 discussed the NS_52 A-MPR requirements for PSSCH_PSCCH and PFSCH for NR V2X UE as follows. Issue 1-1-2: A-MPR for NS_52 for PSSCH_PSCCH and PFSCH transmitted channel for PC3 UE To derive A-MPR requirements, the worst A-MPR values from interested companies are chosen. Tentative agreement: NS_52(FCC) will be captured in TS38.101-1. Recommendations for 2nd round: WF assigned to complete A-MPR for remaining NS_52 channels based on the tentative agreement. The detailed table format and A-MPR level will be proposed in WF.
WF on PSSCH_PSCCH A-MPR for PC3 NR V2X UE at n47 For FCC regulation at 40MHz with NS_52 Option 1 A-MPR(dB) Carrier Modulation frequency(MHz) Region1 Region2 Region3 QPSK 8.0 5.5 16QAM 8.0 5.5 5885 (10.0 + Note1) 64QAM 8.5 5.5 256QAM 8.5 6.0 Note1: is 0, 3, and 5 for 60kHz, 30kHz, and 15kHz SCS, respectively.
WF on PSSCH_PSCCH A-MPR for PC3 NR V2X UE at n47 For FCC regulation at 40MHz with NS_52 Option 2 A-MPR(dB) Carrier Modulation frequency(MHz) Region 1 Region 2 Region 3 QPSK 8.0 5.5 16QAM 8.0 5.5 5885 1514 64QAM 8.5 5.5 256QAM 8.5 6.0
Definition of regions for PSSCH_PSCCH NS_52 A-MPR Option 1 A-MPR parameters Regions Channel Bandwidth, MHz Carrier A-MPR frequency(MHz) RBstart & RBend LCRB RBstart =0 or RBend =NRB-1 LCRB floor(NRB*0.2) Region 1 The RB allocation is in Region 2 allocation for all other allocations which are not an Region1 or Region3 allocation. 40 5885 Region 2 floor(NRB/3.5) RBstart NRB floor(NRB /3.5) LCRB LCRB ceil(NRB/3.5) Region 3
Definition of regions for PSSCH_PSCCH NS_52 A-MPR Option 2 A-MPR parameters Regions Channel Bandwidth, MHz Carrier A-MPR frequency(MHz) RBstart or RBend LCRB LCRB RBstart floor(NRB*0.2) or RBend NRB- floor(NRB*0.2) Region 1 floor(NRB*0.2) The RB allocation is in Region 2 allocation for all other allocations which are not an Region1 or Region3 allocation. 40 5885 Region 2 LCRB floor(NRB/3.5) RBstart NRB floor(NRB /3.5) LCRB Region 3 ceil(NRB/3.5)
WF on PSFCH A-MPR for PC3 NR V2X UE at n47 For FCC regulation at 40MHz with NS_52 For PSFCH all submissions have the same values given below Option 1 Channel Bandwidth [MHz] Carrier frequency [MHz] A-MPR (dB) 40 MHz 5885 23.5
Conclusion Proposed WF is as follows: A-MPR for PSSCH_PSCCH Select option1 or select option 2(tentatively agreed in RAN4#95-e) Definition of regions for PSSCH_PSCCH Select option21 (tentatively agreed in RAN4#95-e) A-MPR for PSFCH Select A-MPR table in slide 7 (tentatively agreed in RAN4#95-e)
