Abstract
A method of adjusting single-stream transmissions by a wireless device based on channel state information (CSI). The wireless device generates a sounding packet formatted for transmission via multiple spatial streams, and transmits the sounding packet to a receiving device via a single one of the multiple spatial streams. For example, the wireless device may be a single-antenna device. The wireless device further receives channel state information (CSI) from the receiving device based at least in part on the sounding packet. The wireless device then adjusts one or more characteristics of single-stream transmissions to the receiving device based at least in part on the received CSI.
