Claim 0:
1. A user equipment (UE) apparatus for wireless communication with a base station, the UE apparatus comprising:
a transceiver; and
a processor configured to:
transmit, to the base station, via the transceiver, at least one uplink (UL) data packet in a radio resource control (RRC) inactive state based on a preconfigured UL resource (PUR) configuration, wherein the PUR configuration is defined according to a set of PUR parameters based on transmissions in the RRC inactive state,
receive, from the base station, via the transceiver, downlink control indicator (DCI) information for reconfiguring the PUR configuration in the RRC inactive state, and
in response to a UL transmission failure, fall back to a random access channel (RACH) transmission mode, and receive, from the base station, via the transceiver, a message indicating the UE to change from the RACH transmission mode to a configured grant-based transmission mode,
wherein the set of PUR parameters include at least one of a control resource set (CORESET) configuration including an aggregation level and repetition types; a physical UL shared channel (PUSCH) repetition configuration including a frequency hopping pattern; or a UL narrow beam direction for frequency range 2 (FR2) or a transmission reception point (TRP) association, and
wherein the set of PUR parameters is associated with new radio (NR).
