WIRELESS LOCAL AREA NETWORK (WLAN) UPLINK TRANSCEIVER SYSTEMS AND METHODS
First Claim
1. An access point for associating with a wireless area network having one or more wireless stations, the access point comprising:
- a processor configured to;
receive, within a single transmit opportunity, a respective metric and a respective resolution from each of a plurality of stations;
determine, within the single transmit opportunity, a group of compatible stations based on the respective metrics and the respective resolutions; and
send, within the single transmit opportunity, a respective configuration to each station in the group of compatible stations based on the respective metrics and the respective resolutions for each station to transmit within the single transmit opportunity.

Abstract
Systems, methods, and instrumentalities are described to implement WLAN uplink multi-user multiple input multiple output (UL MU-MIMO) communication in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 based system, using an IEEE 802.11 station (STA). The STA may receive a downlink poll frame from an IEEE 802.11 access point (AP) including one or more of a request for reporting of a transmit power, a request for a timestamp of a response frame, or a request for an estimated carrier frequency offset (CFO) value. The STA may send an uplink response frame. The uplink response frame may include one or more of transmit power parameters, timestamp parameters, or an estimated CFO value to an AP. The STA may receive a schedule frame, wherein the schedule frame may include indication to adjust one or more of a transmit power, a timing correction value, or a CFO correction value.
