Trigger frame response with network allocation vector
First Claim
1. An apparatus of a station comprising:
- memory; and
, processing circuitry coupled to the memory, the processing circuitry configured to;
decode a first frame of a wireless transmission, the first frame comprising a first duration;
if the first frame is a trigger frame or a multi-user request-to-send (MU-RTS) frame from an access point of a same basic service set (BSS) as the station, respond to the trigger frame or the MU-RTS frame if a network allocation vector (NAV) of the station is not set, or respond to the trigger frame or the MU-RTS frame if the NAV of the station is set and the trigger frame or MU-RTS frame comprises an indicator that indicates not to consider the NAV;
decode a second frame comprising a second duration; and
in response to a determination that the NAV is to be set based on the second frame, set the NAV to the second duration, and if a physical (PHY) header or a media access control (MAC) header of the second frame indicates a bandwidth of the NAV, then set the bandwidth of the NAV to the bandwidth of the NAV indicated by the PHY header or the MAC header otherwise set the bandwidth to an entire bandwidth occupied by the second frame.

Abstract
Computer readable media, methods, and apparatuses to determine whether to respond to a frame based on a network allocation vector. An apparatus of a station comprising memory and processing circuitry coupled to the memory is disclosed. The processing circuitry is configured to: decode a frame comprising a first duration and a first transmitter address, if the frame is a trigger frame or a multi-user request-to-send (MU-RTS) frame from a master station of a basic service set (BSS), respond to the trigger frame or the MU-RTS frame if the trigger frame or MU-RTS frame comprises a NAV indicator that indicates not to consider a network allocation vector (NAV). The indication may be an indication in a physical header or an indication in a media access control header.
