MU-MIMO dynamic bandwidth selection

摘要

Apparatuses and methods are disclosed that may allow a wireless device to dynamically select a bandwidth for MU-MIMO communications. A wireless device may transmit, on each of a plurality of wireless channels, a clear-to-send-to-self (CTS2S) frame that reserves medium access on a number of wireless channels and/or confirms the continued availability of the wireless channels. The bandwidth for a subsequent sounding operation may be based on the bandwidth used to transmit the CTS2S frames. Thereafter, the wireless device may transmit one or more MU-MIMO data frames to a number of other wireless devices using the selected bandwidth.
