Method and apparatus of link adaptation in a wireless local area network system

摘要

A method of transmitting modulation and coding scheme (MCS) feedback (MFB) in a wireless local area network system is provided. The method is performed by a first station and includes receiving, from a second station, a physical layer convergence procedure (PLCP) protocol data unit (PPDU), estimating a MFB based on the PPDU and transmitting, to the second station, feedback information including a MFB field and a MFB type field. The MFB field includes the MFB and the MFB type field indicates whether or not the MFB is in response to a MFB request (MRQ) of the second station.

1. A method of transmitting information on a modulation and coding scheme (MCS) in a wireless local area network system, the method comprising:
receiving, by a first station from a second station, a physical layer protocol data unit (PPDU); configuring, by the first station, a MCS feedback (MFB) based on the PPDU; and transmitting, by the first station to the second station, feedback information including the configured MFB and a MFB type field, wherein the MFB type field indicates whether or not the MFB is configured as a response to a MFB request (MRQ) of the second station, and wherein the feedback information further includes coding information indicating a coding type of the PPDU if the MFB type field indicates that the MFB is not configured as a response to the MRQ of the second station.
