1. A method for wireless communication by a first wireless local area network (WLAN) device, comprising:
communicating a link adaptation test packet between the first WLAN device and a second WLAN device via a wireless channel, the link adaptation test packet including a first test portion modulated with a first modulation and coding scheme (MCS) and a second test portion modulated with a second MCS, wherein the first MCS is different from the second MCS;
obtaining a first link quality metric associated with the first test portion of the link adaptation test packet modulated with the first MCS and a second link quality metric associated with the second test portion of the link adaptation test packet modulated with the second MCS; and
communicating a subsequent packet between the first WLAN device and the second WLAN device via the wireless channel using the first MCS or the second MCS based at least in part on the first link quality metric and the second link quality metric.
