According to examples of present disclosure, a network device may group a first subset of client devices for beamforming transmissions using multi-user multiple-input multiple-output (MU-MIMO), and also group a second subset of client devices associated with the two or more basic service sets for simultaneous data transmission using multi-user orthogonal frequency-division multiple access (MU-OFDMA). The subset of client devices within the same group may be associated with different basic service sets.

Enhancing MU-MIMO to group clients across multiple BSSIDS for a physical radio

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.
