Abstract
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, C 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.
Claims15
A method of transmitting modulation and coding scheme (MCS) feedback (MFB), performed by a first station, in a wireless local area network system, the method comprising:
- 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 including the MFB, the MFB type field indicating whether or not the MFB is in response to a MFB request(MRQ) of the second station.
A station for transmitting modulation and coding scheme (MCS) feedback (MFB) in a wireless local area network system, the station comprises a processor configured to:
- receive, from an Access Point (AP), a physical layer convergence procedure(PLCP) protocol data unit(PPDU);
- estimate a MFB based on the PPDU;
- and,
- transmit, to the AP, feedback information including a MFB field and a MFB type field, the MFB field including the MFB, the MFB type field indicating whether or not the MFB is in response to a MFB request(MRQ) of the AP.
