FIRST MESSAGE DIFFERENTIATION IN CBRA PROCEDURE

摘要

For a random access procedure (e.g., 2-step RACH and/or 4-step RACH), a network node may configure different physical random access preamble configurations (e.g., different PRACH occasions, preamble indexes, or preamble formats) for different user equipment (UE)/service groups that are associated with different UE priorities, UE types, service priorities, service types, and/or network slices. A UE may select a configuration to use to transmit the random access preamble based on the priority of the UE, the type of the UE, the priority of the service, the type of the service, and/or the network slice. In 2-step RACH, a network node may also configure different msgA PUSCH resources for different UE priorities, UE types, service priorities, service types, and/or network slices. The UE may transmit the random access preamble in accordance with the selected PRACH configuration as part of a contention based random access procedure.
