1. A method of wireless communication at a user equipment (UE), comprising:
determining a clear channel assessment (CCA) threshold corresponding to at least one bandwidth, the at least one bandwidth being associated with a channel occupancy time (COT) sharing procedure;
adjusting the CCA threshold corresponding to the at least one bandwidth based on at least one of one or more sensing bandwidths over which energy is measured for a channel access determination or one or more granted resources for the COT sharing procedure, wherein the at least one bandwidth includes a base station transmission bandwidth that is within a UE sensing bandwidth included in the one or more sensing bandwidths;
signaling the adjusted CCA threshold corresponding to the at least one bandwidth to at least one of a node or a base station;
calculating a difference between the UE sensing bandwidth of the one or more sensing bandwidths and a base station sensing bandwidth of the one or more sensing bandwidths; and
adjusting the at least one bandwidth based on the calculated difference between the UE sensing bandwidth and the base station sensing bandwidth,
wherein the difference between the UE sensing bandwidth and the base station sensing bandwidth includes a difference between at least one of a transmit power, a transmit equivalent isotropic radiated power (EIRP), or a transmit power spectral density (PSD).
