Claim 8:
9. A base station apparatus for wireless communication with a user equipment (UE), the base station apparatus comprising:
a transceiver; and
a processor configured to:
receive, from the UE, 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,
transmit, to the UE, 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, indicate the UE to fall back to a random access channel (RACH) transmission mode, and transmit, to the UE 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).
