B.3 NR Operation with Shared Spectrum
38.3003GPPNRNR and NG-RAN Overall descriptionRelease 17Stage 2TS
NR Radio Access operating with shared spectrum channel access can support the following deployment scenarios:
– Scenario A: Carrier aggregation between NR in licensed spectrum (SpCell) and NR in shared spectrum (SCell);
– Scenario A.1: SCell is not configured with uplink (DL only);
– Scenario A.2: SCell is configured with uplink (DL+UL).
– Scenario B: Dual connectivity between LTE in licensed spectrum and NR in shared spectrum (PSCell);
– Scenario C: NR in shared spectrum (PCell);
– Scenario D: NR cell in shared spectrum and uplink in licensed spectrum;
– Scenario E: Dual connectivity between NR in licensed spectrum (PCell) and NR in shared spectrum (PSCell).
Carrier aggregation of cells in shared spectrum is applicable to all deployment scenarios.
