Abstract: A device includes a memory, a processor, and a transceiver. The memory is configured to store capability data corresponding to a set of stations. The processor is configured to select, based at least in part on the capability data, one of a multi-user multiple-input multiple-output (MU-MIMO) mode or an orthogonal frequency-division multiple access (OFDMA) mode for wireless communication with a subset of the set of stations. The transceiver is configured to wirelessly communicate with the subset in the selected one of the MU-MIMO mode or the OFDMA mode.

Abstract: Various aspects are provided for managing a sounding interval of a wireless communications device, which may include setting a timing of one or more channel sounding operations performed by the communications device. For instance, a method is provided for channel sounding management. This example method may include obtaining information regarding a modulation and coding scheme (MCS) or a throughput degradation gradient associated with one or more transmissions. In addition, the example method may include determining a timing of one or more sounding operations based on the information regarding the MCS or the throughput degradation gradient. Additionally, apparatuses and computer-readable media are provided for channel sounding management in a communications device, which are configured to perform, or store computer-executable code to perform, the disclosed example methods.

Abstract: Methods, systems, and apparatuses are described for wireless communications. More particularly, an access point (AP) identifies a plurality of multi-user multiple-input multiple-output (MU-MIMO) groups associated with a wireless station (STA). The AP determines a communication metric associated with each of the plurality of MUMIMO groups. The communication metric provides an indication of the compatibility of the STAs in the MU-MIMO group. The AP prioritizes at least one of the plurality of MU-MIMO groups based at least in part on the communication metric associated with the prioritized MUMIMO group. The AP creates a preferred group list and/or a blacklisted group list and included the prioritized MU-MIMO group in the appropriate group list.
