1. An apparatus for wireless communication at a user equipment (UE), comprising:
a memory; and
at least one processor coupled to the memory and configured to:
perform at least one energy sensing measurement over an operating channel, wherein the at least one energy sensing measurement comprises a plurality of energy sensing measurements measured over different subbands of the operating channel;
determine whether the operating channel is available for transmission based on a threshold determination for one or more transmission power levels measured over a bandwidth of the operating channel; and
transmit on the operating channel upon a determination that the operating channel is available for transmission for the one or more transmission power levels, wherein the one or more transmission power levels are less than the threshold determination.
