Abstract
A method implemented by a first network device in a Wireless Local Area Network (WLAN) to provide Modulation Coding Scheme (MCS) feedback. The method includes selecting an MCS that is determined to have a highest data rate among a plurality of available MCSes that when used to transmit a frame having a reference payload size over a wireless communications link between the first network device and a second network device results in a frame error rate that is less than or equal to a threshold error rate for a given set of transmission properties, generating a frame having a Media Access Control (MAC) header, wherein a control field of the MAC header includes an indication of the selected MCS, and transmitting the generated frame to the second network device through a wireless medium.
