    Abstract: A user equipment (UE) includes a memory and a processor configured to perform directional listen before talk (LBT) to identify a set of narrow beam and sub-band combinations available for transmission; transmit, to a base station (gNB), at least one schedule request in a physical uplink control channel (PUCCH) over the identified set of narrow beam and sub-band combinations; receive, from the gNB, an uplink grant for physical uplink shared channel (PUSCH) data transmission over at least one narrow beam and sub-band combination selected by the gNB from the identified set of narrow beam and sub-band combinations; and acquire a channel occupancy time (COT) duration for the at least one narrow beam and sub-band combination selected by the gNB as part of the uplink grant.

    Abstract: A user equipment (UE) apparatus for wireless communication with a base station is provided. The UE includes a transceiver and a processor. The processor is 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, 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).
