3 GPP TSGRAN WG 494 eBis Meeting Electronic

3 GPP TSG-RAN WG 4#94 -e-Bis Meeting Electronic Meeting, 20 – 30 Apr. , 2020 R 4 -2005634 WF on TR/TS structures and common terminology for NR V 2 X UE vivo, Qualcomm, . . .

Background • In this meeting, there are two contributions discussing on the specification issues and common terminology for NR V 2 X. • R 4 -2003674, “Considerations on improving the draft TR and TS for NR V 2 X” (vivo) • R 4 -2003881, “NR V 2 X specification structure for interband concurrent requirements in 38. 101 -1” (Qualcomm)

Specification structure and common terminology Issue 1 -Clause separation and suffix for V 2 X • • Option 1: Suffix E for NR V 2 X including sidelink standalone, con-current operation, and V 2 X bands. Option 2: Clause suffix E for V 2 X sidelink standalone requirements and bands, clause suffix Ea for V 2 X interband concurrent-specific requirements and bands. Table 4. 3 -1: Definition of suffixes Clause suffix None A B C D E Ea • Variant Single Carrier Aggregation (CA) Dual-Connectivity (DC) Supplement Uplink (SUL) UL MIMO V 2 X Sidelink Standalone V 2 X Interband Concurrent Option 3: Create separate sub-clauses for these four sets of RF requirements for NR V 2 X in FR 1 for TR 38. 886: • Single carrier operation in ITS band • Single carrier operation in NR V 2 X licensed bands • Concurrent operation for NR V 2 X • SL MIMO operation for NR V 2 X

Issue 2 - General Requirements • Option 1 • General requirements shall apply to V 2 X communication unless excepted. • Consistent with existing 36. 101/38. 101 spec structure and eliminates multiple single-line references to general requirements • Option 2 • General requirements for smart phone type V 2 X UE. The UE shall satisfy the general and suffix ‘E’ UE • The Vehicle type UE only satisfy the Suffix ‘E’ requirement for V 2 X UE

Specification structure and common terminology Issue 3 -Notation for NR V 2 X con-current operation • Option 1: EN-V 2 X_X_n. Y • Option 2: V 2 X_X_n. Y Issue 4 -Removal of FR 2 in TR 38. 886 • • Option 1: Remove all the chapter titles including FR 2 from TR 38. 886 and add a description in TR 38. 886 all the requirements apply for FR 1. New TR can be created for capturing FR 2 requirements for NR V 2 X in future. Option 2: Do not Remove all the chapter titles including FR 2 from TR 38. 886 Issue 5 -Merge co-existence study chapter • Option 1: Merge Chapter 5 and Chapter 6 as one chapter for co-existence evaluation in TR 38. 886. • Option 2: keep the current chapter since section 5 is for adjacent channel coexistence and the other is for self desense analysis in a UE

Specification structure and common terminology Issue 6 -Switch the chapter arrangement for TR 38. 886 • Option 1: Switch the chapter arrangement for Chapter for operating bands and Chapter for coexistence study in TR 38. 886. • Option 2: Keep the current spec structure Issue 7 -Clause title for NR V 2 X • The clause titles are captured in the endorsed draft CRs and TPs for NR V 2 X as follows: • • Option 1. ‘XXX for V 2 X communication’ Option 2. ‘XXX for V 2 X’ Option 3. ‘XXX for NR V 2 X UE’ Option 4. ‘XXX for NR V 2 X’

Specification structure and common terminology Issue 8 -Duplex mode for NR SL • For the duplex mode, there is a misalignment between ‘TDD’ and ‘HD’ for band n 47. • Option 1: TDD • Option 2: HD
