R4-2005225 3GPP TSG-RAN WG4 NR #94-e-Bis 20th - 30th Apr 2020 WF on MPR/A-MPR requirements for S-SSB transmission Qualcomm 1
S-SSB MPR_A-MPR candidate options Issue 1-3-1: MPR for S-SSB transmission Option 1: The allowed MPR of NR V2X S-SSB follow the NR Uplink MPR requirements specified in sub-clause 6.2.2 from TS 38.101-1. The MPR value is same for each of the channels for S-SSB transmission. Option 2: Define the new MPR requirements for NR V2X S-SSB based on simulation results. The MPR value is same for each of the channels for S-SSB transmission. MPR requirements based on inner, outer allocations1. Option 3: Define the new MPR requirements for NR V2X S-SSB based on simulation results. The MPR value is different for each of the channels for S-SSB transmission. MPR requirements based on inner, outer allocations1. Issue 1-3-2: A-MPR for S-SSB transmission Option 1: Define A-MPR requirements for both 10MHz (EU NS_33) and 40MHz (FCC NS_48) according to inner/outer regions. Consider the merged A-MPR values (using average manner) from interested companies. The A-MPR value is same for each of the channels for S-SSB transmission. Option 2: Define A-MPR requirements for both 10MHz (EU NS_33) and 40MHz (FCC NS_48) according to inner/outer regions. Consider the worst A-MPR values from interested companies. The A-MPR value is same for each of the channels for S-SSB transmission. Option 3: Define A-MPR requirements for 10MHz (EU NS_33) and 10MHz (EU NS_NEW) without coexistence and 40MHz (FCC NS_48) according to RB start. Consider the worst A-MPR values from interested companies. The A-MPR value is same for each of the channels for S-SSB transmission. Note1: Inner and outer allocations based on sect. 6.2.2 TS38.101-1 2
WF on MPR/A-MPR requirements for S-SSB transmission The following options are suggested as a WF on MPR/A-MPR requirements for S-SSB transmission: Issue 1-3-1: MPR for S-SSB transmission Option 2: Define the new MPR requirements for NR V2X S-SSB based on simulation results. The MPR value is same for each of the channels for S-SSB transmission. MPR requirements based on inner, outer allocations1.
