Section: 16.9.3 Radio Resource Allocation 16.9.3.1 General
Content: For NR sidelink communication, the UE can operate in two modes as specified in 5.7.2 for resource allocation in sidelink: - Scheduled resource allocation, characterized by: - The UE needs to be RRC_CONNECTED in order to transmit data; - NG-RAN schedules transmission resources. - UE autonomous resource selection, characterized by: - The UE can transmit data when inside NG-RAN coverage, irrespective of which RRC state the UE is in, and when outside NG-RAN coverage; - The UE autonomously selects transmission resources from resource pool(s). For NR sidelink communication, the UE performs sidelink transmissions only on a single carrier.
