3 GPP TSGRAN WG 4 96 e August

3 GPP TSG-RAN WG 4 #96 -e August 17 th – 28 th, 2020 Electronic meeting R 4 -200 XXXX NR-U System Parameters GTW status Moderator (Ericsson)

Background There are three major topics under discussion: • Topic #1: Introduction of 6 GHz band considering band plan and channelization • Topic #2: System parameters considering 100 MHz CBW in NR-U Rel 16 and Spectrum Utilization • Topic #3: Wideband capabilities

Introduction of 6 GHz band Issue 1 -2: Channelization Proposals • Option 1: Do not reuse the same channel allocation as 802. 11 ax. Revised channelization on top of 802. 11 ax should be considered for 6 GHz band in NRU. • Option 2: Adopt the following proposals: • It is proposed to introduce at least 20 MHz, 40 MHz, 60 MHZ, and 80 MHz channel bandwidths for NR-U band in 6 GHz unlicensed band. • It is proposed to align channel raster for NR-U in band n 96 with Wi-Fi channels in 6 GHz. • It is proposed to set 60 MHz channels only within 80 MHz channel i. e. to adopt channel bonding rule for 60 MHz CBW. • It is proposed to introduce 15 k. Hz as global frequency raster for band n 96 and NREF numbers for respective CBW as in table 1 in R 4 -2010744. • It is proposed to introduce band n 46 principles for synchronization raster for band n 96 and GSCN numbers for respective CBW as in table 2, R 4 -2010744. • Status : • Option 1: Huawei, ZTE, Media. Tek, CHTTL, CMCC, China Telecom • Option 2: QC, Charter, SKW, Nokia, LG, Apple, Verizon, Intel, Cable. Labs, AT&T Agreements: • • Assuming the requirements for band plan (5925 – 7125 MHz) can be completed at this meeting, go with option 2. If the requirements are not completed, channelization will be further discussed. • If there is updates from IEEE/Wi. Fi Alliance, the channelization and related requirements should be further updated. Option 2 is for operation in the US only. It is recognized that a different channelization may be needed for other regions.

NR-U System parameters Issue 2 -1 -1: 100 MHz channel bandwidth Proposals • Option 1: Define 100 MHz channel bandwidth for NR-U in 5 GHz (Huawei) • Option 2: Do not define 100 MHz channel bandwidth for NR-U in 5 GHz (n 46) in Release 16 (Charter) Status : • Option 1: 2 companies: Huawei, ZTE • Option 2: 9 companies: QC, Charter, SKW, Nokia, LG, Apple, Verizon, Intel, Cable. Labs • Tentative agreement: • Option 2 : Given limited time for Rel-16, 100 MHz channel requirements can not be completed in Rel-16, this can be further discussed in Rel-17

Introduction of 6 GHz band Issue 1 -3: AFC functionality and coexistence with ITS • Define AFC functionality for NR-U operation • Study coexistence between NR-U operation in 6 GHz and ITS in band n 47 Proposals • Agreeable • Not agreeable • Status : Option 1: 4 companies: Huawei, ZTE, Media. Tek, CHTTL Option 2: 10 companies: QC, Charter, SKW, Nokia, LG, Apple, Verizon, Intel, Cable. Labs, Ericsson • Tentative Agreement: • Not agreeable, AFC is out of scope of 3 GPP

NR-U System parameters Issue 2 -2: Spectrum Utilization Proposals • Option 1: • 25 PRB for 20 MHZ channel bandwidth should be mandatory for a UE supporting 60 k. Hz SCS. • 25 PRBs for 60 k. Hz intra-carrier guard bands should be supported. • Option 2 : • 24 RBs for 20 MHz channel with 5 RBs for in-carrier guard band • Status : • Option 1: 4 companies: Huawei, ZTE, Media. Tek, CHTTL • Option 2: 9 companies: QC, Charter, SKW, Nokia, LG, Apple, Verizon, Intel, Cable. Labs • Agreements: • TBD

Introduction of 6 GHz band Issue 1 -1: 6 GHz Band plan Proposals • Option 1: Consider following bands for 6 GHz: • Standard-power operation: Band x: 5925 - 6425 MHz, Band z: 6525 - 6875 MHz • Indoor operation: Band y: 5925 - 7125 MHz • Option 2: To include band n 96 for NR-U with 5925 – 7125 MHz range. • Option 3: First specify the requirements then define the band plan • Status : • Option 1: 3 companies: Huawei, BT, DT • Option 2: 10 companies: QC, Charter, SKW, Nokia, LG, Apple, Verizon, AT&T, Qorvo, U. S. Cellular • Option 3: 3 companies: ZTE, Media. Tek, CHTTL Agreements: • Agreed on 5925 – 7125 MHz range as the band plan, assuming all the requirements including system parameters and the UE and BS requirements can be completed at this meeting. If not completed, the band plan will be further discussed in future RAN 4/RAN meetings. • This band is intended for operations subject to FCC NPRM RNO (needs to be clearly specified in the specifications) • It does not preclude specification of other bands or use of other bands in the same frequency range in other regions
