Abstract
Wireless communications systems and methods related to channel access contention management in a shared radio frequency band are provided. A first wireless communication device performs, during a first time period, a first clear channel assessment (CCA) in a shared radio frequency band based on a first energy detection threshold, wherein performing the first CCA comprises obtaining at least one signal energy measurement. The first wireless communication device then performs, during a second time period subsequent to the first time period, a second CCA in the shared radio frequency band based on a second energy detection threshold, the second energy detection threshold being based on the at least one signal energy measurement. The wireless communication device then transmits, to a second wireless communication device in the shared radio frequency band based on the second CCA, a communication signal.
