NR-U Control plane (Candidates)

  November 25, 2020    

 Note: NR-Unlicensed is still in the study phase with barely any work done on the TS. It is expected that by 2022 (so Release 18) we may see some specification for the 6GHz band in Europe. As of now, only potential candidates for NR-U implementation can be guessed. RLM/RLF and mobility For non-standalone NR-U deployments, connected mode mobility is supported on licensed spectrum using the...

NR-U Layer 2 (Candidates)

  November 25, 2020    

 Note: NR-Unlicensed is still in the study phase with barely any work done on the TS. It is expected that by 2022 (so Release 18) we may see some specification for the 6GHz band in Europe. As of now, only potential candidates for NR-U implementation can be guessed. RACH (4-step, 2-step) Both 4-step and 2-step RACH will be supported for NR-U. Here 2-step RACH refers to the procedure...

NR-U Physical Frame structure (Candidates)

  November 25, 2020    

NR-Unlicensed is still in the study phase with barely any work done on the TS. It is expected that by 2022 (so Release 18) we may see some specification for the 6GHz band in Europe. As of now, only potential candidates for NR-U implementation can be guessed. Physical layer aspectsNR-U supports both Type-A and Type-B mapping already supported in NR. Initial active DL/UL BWP is approximately 20MHz...

NR-U Channel Access Schemes (Candidates)

  November 25, 2020    

 Note: NR-Unlicensed is still in the study phase with barely any work done on the TS. It is expected that by 2022 (so Release 18) we may see some specification for the 6GHz band in Europe. As of now, only potential candidates for NR-U implementation can be guessed. The channel access candidate schemes for NR-based access for unlicensed spectrum can be classified into the following categories: -   ...
