Method, wireless device, and computer readable medium for conducting a multiple station beam refinement protocol in a wireless network

A non-transitory computer-readable storage media that stores instructions for execution by one or more processors to perform operations to execute a multiple station beam refinement protocol on a wireless device, the instructions comprising:

• instructions to generate a trigger frame to initiate a multiple station beam refinement protocol (MSBRP) with two or more stations (STAs), that have associated with the wireless device, wherein the two or more stations comprise at least a first station and a second station the two or more stations that will participate in the MSBRP identified with an identifier (ID);
• instructions to generate for transmission to the first station and the second station a first sector sweep (SSW) frame including parameters corresponding to each sector of a first plurality of sectors, wherein each of the first plurality of sectors correspond to a weight vector for the plurality of antennas;
• in a per-STA phase:
• instructions to receive from the first station a second SSW frame including parameters identifying a second plurality of sectors;
• instructions to select a first sector to use for the first station based on a first measurement, the first measurement based on the second SSW frame;
• instructions to receive from the second station a third SSW frame including parameters identifying a third plurality of sectors;
• instructions to select a second sector to use for the second station based on a second measurement, the second measurement based on the third SSW frame;
• and
• instructions to generate for transmission to the two or more stations feedback to indicate the first sector and the second sector that the first station and second station are to use respectively to transmit to the wireless device.
