Abstract
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a link adaptation protocol in a wireless local area network (WLAN). In one aspect, the link adaptation protocol may be used to select a transmission rate option (such as a modulation and coding scheme (MCS)) for communications from a first WLAN device to a second WLAN device based on wireless channel conditions. This disclosure includes several example message sequences for the link adaptation protocol which can accommodate a variety of uplink or downlink data transmission designs, including single user (SU) and multi-user (MU) transmissions. The example message sequences may be used with orthogonal frequency division multiple access (OFDMA), multiple-input-multiple-output (MIMO), and beamformed transmissions.
