APPARATUS AND METHOD FOR NETWORK ALLOCATION VECTOR OPERATIONS

摘要

In wireless communications, an access point may send a trigger frame to multiple stations. The trigger frame may include a carrier sense required subfield that can be set to a first state or a second state. The carrier sense required subfield indicates whether the stations are required to consider a status of carrier sensing in determining whether or not to respond to the trigger frame. A station that receives a trigger frame having the carrier sense required. subfield set to the first state may send a response at a predetermined time interval without performing a carrier sense operation. A station that receives a trigger frame having the carrier sense required subfield set to the second state may determine whether to send a response based on performing a carrier sense operation.

主权项

1. A station for facilitating multi-user communication in a wireless network, the station comprising:
one or more memories; and one or more processors coupled to the one or more memories, the one or more processors configured to cause:
receiving a trigger frame, wherein the trigger frame solicits an uplink multi-user transmission as an immediate response, and wherein the trigger frame comprises an indication associated with carrier sensing;when the indication is set to a first state, transmitting an uplink frame as the immediate response to the trigger frame without performing carrier sensing; andwhen the indication is set to a second state:
performing a carrier sensing; anddetermining whether or not to transmit the uplink frame as the immediate response to the trigger frame based on a result of the carrier sensing.
