Abstract
A method to operate a wireless access point (WAP) that includes identifying multiple stations from uplink statistics of a plurality of uplinks and determining an optimal spatial state of an antenna array for reception of the plurality of uplinks. Channel state information (CSI) is evaluated for each antenna in the antenna array. Determining the optimal spatial state of the antenna array includes using the CSI for each antenna to extrapolate the optimal spatial state of the antenna array for the plurality of uplinks. The method further includes changing a spatial state of the antenna array to the optimal spatial state.
Claims14
A method, comprising:
- sending a trigger frame to a station, the trigger frame indicating a spatial state for one or more spatial streams in a multiple input, multiple output (MIMO) configuration;
- establishing an uplink with the station;
- identifying uplink statistics related to the uplink with the station;
- determining, for the uplink, an updated spatial state for the uplink;
- and
- changing a spatial state for the station to correspond to the updated spatial state.
