Methods, architectures, apparatuses and systems for coordinated spatial reuse transmissions

A method implemented in a first access point (AP), comprising:

• transmitting a first transmission;
• transmitting, to a first station (STA) associated with the first AP, a first frame that requests received power measurement information;
• receiving from the first STA a second frame that includes the requested received power measurement information, wherein the requested received power measurement information indicates:
• (i) first received power measurement information associated with the first transmission measured at the first STA, and (ii) second received power measurement information associated with a second transmission received from a second AP and measured at the first STA, wherein the first STA is not associated with the second AP;
• transmitting, to the second AP, a trigger frame that includes a second AP identifier and a first indication of first transmit power adjustment information for the second AP based on the indicated first and second received power measurement information, wherein the second AP identifier identifies the second AP;
• and
• transmitting, to the first STA a third transmission that shares a same set of resources as the second AP used for a fourth transmission, wherein transmitting the third transmission over the same set of resources as the second AP used for the fourth transmission is based on the first transmit power adjustment information for the second AP.

A second access point (AP) comprising circuitry, including a transmitter, a receiver, a processor, and memory, configured to:

• transmit a first transmission;
• receive from a first AP a trigger frame indicating a second AP identifier and an indication of transmit power adjustment information for the second AP, wherein the indication of transmit power adjustment information is based on the first transmission and wherein the second AP identifier identifies the second AP;
• and
• transmit, to a STA associated with the second AP, a fourth transmission that shares a same set of resources as the first AP used for a third transmission, wherein transmitting the fourth transmission over the same set of resources as the first AP used for the third transmission is based on the transmit power adjustment information for the second AP.
