Cca clearance in unlicensed spectrum

A method of wireless communication at a user equipment (UE), comprising:

• measuring, by the UE, a shared channel during at least one time duration equivalent to a clear channel assessment (CCA) time duration prior to performing a CCA;
• determining, by the UE, a channel condition of the shared channel during the at least one time duration based at least in part on the measuring;
• and
• adjusting, by the UE, prior to performing the CCA, at least one of a transmit power associated with a transmission from the UE following the CCA or a CCA threshold level of the CCA, wherein the adjusting is based at least in part on the determined channel condition;
• and
• performing, by the UE, the CCA based at least in part on the adjusting, wherein the CCA is performed subsequent to the at least one time duration and during an OFDM symbol period identified for use by the base station.
