Link adaptation using transmission rate options

An apparatus of a second wireless device, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the second wireless device to:
• receive, from a first wireless device via a wireless channel, a first packet that includes a plurality of link adaptation test portions generated using a plurality of transmission rate options;
• transmit, to the first wireless device, feedback information based at least in part on the plurality of link adaptation test portions;
• and
• receive, from the first wireless device via the wireless channel and based at least in part on the feedback information, a subsequent packet transmitted using a first transmission rate option of the plurality of transmission rate options.

A method for wireless communication at a first wireless device, comprising:

• transmitting, to a second wireless device via a wireless channel, a first packet that includes a plurality of link adaptation test portions generated using a plurality of transmission rate options;
• receiving, from the second wireless device, feedback information based at least in part on the plurality of link adaptation test portions;
• and
• transmitting, to the second wireless device via the wireless channel and based at least in part on the feedback information, a subsequent packet using a first transmission rate option of the plurality of transmission rate options.
