Systems, apparatuses, methods, and non-transitory computer-readable storage devices for link adaptation in wireless local area network

A communication method comprising:

• a first communication device sending a block acknowledgement request (BAR) frame to a second communication device through a communication link, wherein the BAR frame comprises a link adaptation information request for feedback of at least one link adaptation parameter of the communication link;
• and
• the first communication device receiving a block acknowledgement (BA) frame from the second communication device through the communication link, wherein the BA frame comprises a link adaptation information response relating to the at least one link adaptation parameter of the communication link.

A communication method comprising:

• a first communication device sending a block acknowledgement (BA) frame to a second communication device through a communication link, wherein the BA frame comprises a recommendation for increasing a modulation and coding scheme (MCS) level of the communication link between the first communication device and the second communication device.
