RECEIVER ASSISTED TRANSMITTER SENSING FOR CHANNEL ACCESS

Abstract:

Systems and methods implementing receiver assisted channel access procedures configured to enable access for a potential transmitter while avoiding introducing unacceptable interference with respect to ongoing communications in a shared channel are described. In examples, a receiver assisted channel access procedure implements a LBT enhanced CCA (eCCA) technique in which receiver assisted transmitter sensing is utilized. A receiver assisted channel access procedure may implement monitoring of a shared channel during a contiguous contention period for one or more instances of a periodic session protection signal.
