Abstract:
1. A method, comprising: receiving an end of transmission (EOT) request at an access point (AP) from a client prior to an end of an existing transmit opportunity (TXOP) between the client and the AP, wherein the EOT request truncates the TXOP early, before a network allocation vector (NAV) clears around the client; and transmitting an EOT frame from the AP responsive to receiving the EOT request, wherein the EOT frame has a receiver address field set to a broadcast address and that is configured to separately truncate the TXOP early, before the network allocation vector clears around the AP prior to the end of the TXOP, such that the EOT frame is to be received by all stations in a basic service set (BSS) so that all stations in the basic service set (BSS) resume their backoff at substantially the same time to avoid an extended interval frame space (EIFS) interval.
