BANDWIDTH DEPENDENT CARRIER SENSING FOR OFDMA

摘要

Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to bandwidth dependent carrier sensing for orthogonal frequency division multiple access (OFDMA). One example apparatus for wireless communications generally includes a first interface for obtaining at least a first frame with an indication of a time duration during which at least one bandwidth channel is occupied; a processing system configured to track, based at least in part on the indicated duration, availability of time and one or more resources on a plurality of bandwidth channels including the at least one bandwidth channel and to determine whether resources are available to transmit at least a second frame, based on the tracked availability; and a second interface for outputting the second frame for transmission if the determination indicates resources are available.
