Abstract: A system is disclosed in which an item of user equipment (UE) obtains a reference signal received power (RSRP) threshold value for transmitting a random access message (MsgA) comprising both a preamble part and a Physical Uplink Shared Channel (PUSCH) transmission part. The UE obtains information identifying at least one respective offset associated with at least one priority level, and determines a type of random access procedure (two-step or legacy random access procedure) to be performed based on an RSRP measured by the UE, the RSRP threshold value, and a priority level associated with the UE.

Abstract: A system is disclosed in which a user equipment (UE) performs small data transmission procedure in Radio Resource Control (RRC) Inactive state using a configured grant or random access. As part of this procedure, the UE receives configuration information for controlling subsequent small data transmissions. For example, the configuration information may be used to re-activate, re-configure, or release a configured grant stored by the UE.
