Trigger frame in wireless local area network

A wireless station (STA) for wireless communications, comprising:

• a memory configured to store instructions for controlling transmission power of the STA;
• a processor communicatively coupled with the memory, the processor configured to execute the instructions to:
• receive at a station (STA), a trigger frame from a first access point (AP);
• decode at least a spatial reuse subfield in the trigger frame to identify one or more of transmit power of the first AP or acceptable interference level of the first AP;
• and
• calculate a transmit power of the STA based at least in part on the transmit power of the first AP or the interference level of the first AP.

An apparatus for wireless communications, comprising:

• means for receiving, at a station (STA), a trigger frame from a first access point (AP),
• means for decoding at least a spatial reuse subfield in the trigger frame to identify one or more of transmit power of the first AP or acceptable interference level of the first AP;
• and
• means for calculating a transmit power of the STA based at least in part on the transmit power of the first AP or the interference level of the first AP.
