    Abstract: Examples described herein provide enhanced client grouping by a network device. Examples include determining that a plurality of client devices each comprising a plurality of receiver antennas are associated with a network device, and grouping the client devices into one or more groups, wherein each group comprises a number of client devices less than or equal to the number of transmitter antennas of the network device. Examples include, for each group, assigning one spatial stream to one receiver antenna for each client device of the group, and based on a determination that the number of client devices of the group is greater than one and less than the number of transmitter antennas, assigning one spatial stream to each of a portion of the remaining receiver antennas of the group, wherein at least one receiver antenna of the group is not assigned a spatial stream.

  • Patent number: 10193610
    Abstract: MU-MIMO provides a mechanism for a wireless network device to transmit to multiple client devices at the same time. When employing MU-MIMO, a network device may group two or more associated client devices, and transmit beamformed signals to each group. In some implementations, a network device may initiate channel sounding. Channel sounding may include transmitting sounding frames to client devices associated with two or more basic service sets. Channel sounding may facilitate beamforming transmissions to client devices associated with the two or more basic service sets. The network device may receive feedback frames from client devices associated with the two or more basic service sets. A feedback frame may indicate how a sounding frame was received. In some implementations, the network device may further construct a feedback table from the feedback frames. The feedback table may facilitate grouping of the client devices for beamforming transmissions.
