Abstract: An example communications device includes communications circuitry and control circuitry. The communications circuitry may wirelessly communicate with client devices. The control circuitry may determine signal-to-interference-plus-noise ratios (SINRs) for the client devices based on compressed client-side channel state information received from the client devices. The control circuitry may select, based on the SINRs and in consideration of multiple possible bandwidth settings, a set of multi-user-multiple-input-multiple-output (MU-MIMO) groups each with an assigned bandwidth setting.

Abstract: An example communications device includes communications circuitry and control circuitry. The communications circuitry may wirelessly communicate with multiple receiver antennas concurrently via multiple transmit antennas. The control circuitry may execute an adaptive sounding process that may include, for each client connected to the communications device, performing a follow-up sounding for the client in response to determining that all of the following conditions are jointly satisfied: (a) a wireless channel of the client has significantly changed, as determined based on a channel correlation metric; (b) a wireless throughput has significantly decreased, as determined based on a throughput gradient metric; and (c) the client had a significant amount of recent traffic, as determined based on a traffic metric.

Abstract: Examples described herein relate to adapting a radio of a millimeter-wave device. In some such examples, the millimeter-wave device is to include a first radio to operate at a first beam direction based on a first set of channel state information (CSI). The millimeter-wave device is also to include a second radio to measure a second set of CSI. The millimeter-wave device is then to include a set of instructions to adapt the first radio to operate at an adapted beam direction based on a third set of CSI. The third set of CSI is to include a signal strength at the adapted beam direction that the millimeter-wave device is to determine based on the first set of CSI and the second set of CSI.

Abstract: In some examples, a method includes estimating a signal-to-interference-plus noise ratio (SINR) value between a wireless client and each Access Point (AP) of a plurality of APs based on Channel State Information (CSI) between the wireless client and each AP of the plurality of APs and selecting an AP of the plurality of APs to be associated with the wireless client based on a channel bandwidth of the wireless client and the estimated SINR value between the wireless client and each AP of the plurality of APs.
