Improved CCA clearance in the unlicensed spectrum

摘要

Describes techniques for contention-based wireless communication channel access that can improve the likelihood that contention procedures will pass and allow devices to transmit uplink or downlink transmissions using contention-based channels Is done. Various disclosed techniques may determine transmit power for subsequent transmissions based on channel characteristics during one or more Clear Channel Assessment (CCA) durations. The transmit power may be selected to provide a CCA threshold that may increase the likelihood that the device will win contention for the channel during the CCA procedure.
