1. A base station (BS) in a wireless communication system including a carrier operating with shared spectrum channel access, the BS comprising:
a transceiver configured to transmit, to a user equipment (UE), a channel access request (CARQ) over a downlink channel, wherein the CARQ indicates information related to a set of beam directions to sense for channel access; and
a processor operably coupled to the transceiver, the processor configured to determine a set of time or frequency domain resources for receiving uplink control information (UCI), wherein the UCI includes a channel access response (CARP) and the CARP includes a response to information indicated in the CARQ,
wherein the transceiver is further configured to receive the UCI based on the determined set of time or frequency domain resources, and
wherein the response includes a set of measurement results for responding to the set of beam directions to sense for channel access.
