Claim 16:
17. A base station apparatus for wireless communication with a user equipment (UE), the base station apparatus comprising:
a transceiver; and
a processor configured to:
transmit, to the UE, via the transceiver, signaling information to reconfigure a preconfigured uplink (UL) resource (PUR) for receiving at least one UL data packet from the UE in a radio resource control (RRC) inactive state, wherein the PUR reconfiguration 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 reconfiguration 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 resource allocation in a frequency, time or spatial domain,
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,
a periodicity of the PUR,
a modulation and coding scheme (MCS),
a transport block size (TBS),
a UL narrow beam direction for frequency range 2 (FR2) or a transmission reception point (TRP) association,
an activation or deactivation of the PUR,
a transmission power (Tx) adjustment, or
a time alignment (TA), and
wherein the set of PUR parameters is associated with new radio (NR).
