US 2023/0412330 A1 · BACKOFF COUNTER AND TXOP DURATION SETTINGS FOR COORDINATED ACCESS POINT TRANSMISSIONS

Abstract

This disclosure provides systems, methods and apparatuses for wireless communications. In some implementations, a first access point (AP) may identify other APs to participate in a coordinated access point transmission session, may obtain a transmit opportunity (TXOP) for transmitting wireless signals over a frequency bandwidth, may allocate corresponding portions of the frequency bandwidth to the identified APs for downlink (DL) transmissions during the TXOP, may select a duration of the TXOP for the coordinated access point transmission session based at least in part on an amount or percentage of the first AP's frequency bandwidth that is allocated to the one or more identified APs for the coordinated access point transmission session, and may output information indicative of at least one of the selected TXOP duration or the corresponding portions of the frequency bandwidth allocated to the respective identified AP by the first AP.

Dependent claims

A first wireless access point (AP), comprising:

a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the first wireless AP to:
identify one or more other wireless APs to participate with the first wireless AP in a coordinated AP transmission session during which each of the one or more other identified wireless APs has an opportunity to communicate with one or more respective stations (STAs);
decrement a first back-off counter of the first wireless AP in association with the first wireless AP contending for access to a wireless channel;
transmit, to each of the one or more other identified wireless APs, a respective indication of an ability of the other identified wireless AP to pause decrementing of a respective back-off counter of the other identified wireless AP in accordance with the participation of the other identified wireless AP in the coordinated AP transmission session;
and
commence the coordinated AP transmission session over the wireless channel in accordance with the first back-off counter being decremented to less than a value.

3 more elements

A method for wireless communication by a first access point (AP), comprising:

identifying one or more other wireless APs to participate with the first wireless AP in a coordinated AP transmission session during which each of the one or more other identified wireless APs has an opportunity to communicate with one or more respective stations (STAs);
decrementing a first back-off counter of the first wireless AP in associated with the first wireless AP contending for access to a wireless channel;
transmitting, to each of the one or more other identified wireless APs, a respective indication of an ability of the other identified wireless AP to pause decrementing of a respective back-off counter in accordance with the participation of the other identified wireless AP in the coordinated AP transmission session;
and
commencing the coordinated AP transmission session over the wireless channel in accordance with the first back-off counter being decremented to less than a value.
