1. A method of wireless communication, comprising:
receiving, by a user equipment (UE), a message including a sensing bandwidth configuration for a listen-before-talk (LBT) sensing window over which the UE is to perform a clear channel assessment (CCA) procedure to determine whether a channel in an unlicensed spectrum is available for a data transmission over a transmission bandwidth, wherein the sensing bandwidth configuration for the LBT sensing window is generated by a network entity for the LBT sensing window based on a sensing bandwidth configured by the network entity and specifies a plurality of LBT subbands of the LBT sensing window for the CCA procedure, and wherein the sensing bandwidth configuration defines one or more of: a bandwidth of a LBT subband of the plurality of LBT subbands of the LBT sensing window, and a size for each of a plurality of LBT subbands of the plurality of LBT subbands of the LBT sensing window;
performing the CCA procedure on at least one LBT subband of the plurality of LBT subbands of the LBT sensing window;
determining, based on performing the CCA procedure on the at least one LBT subband of the plurality of LBT subbands of the LBT sensing window, that the channel in the unlicensed spectrum is available for the data transmission over the transmission bandwidth; and
transmitting data of the data transmission over the transmission bandwidth.
