    Abstract: A method of transmitting information on a modulation and coding scheme (MCS) in a wireless local area network system is provided. A responding station receives a physical layer protocol data unit (PPDU) from a requesting station, configures a MCS feedback (MFB) based on the PPDU, and transmits feedback information to the requesting station. If the MFB is configured as a response to a MFB request (MRQ) of the requesting station, the feedback information includes the configured MFB and a MFB type field indicating that the MFB is configured as a response to the MRQ of the requesting station. If the MFB is not configured as a response to the MRQ of the requesting station, the feedback information includes the configured MFB, a MFB type field indicating that the MFB is not configured as a response to the MRQ of the requesting station, and coding information indicating a PPDU coding type.

    Abstract: A method, and a device, for reporting channel state information (CSI) in a wireless local area network system are discussed. The method according to one embodiment includes receiving, by a responding station, a sounding Physical layer Protocol Data Unit (PPDU) from a requesting station; and transmitting, by the responding station, a CSI report to the requesting station, the CSI report including CSI report information in a form of angles representing a beamforming feedback matrix that is estimated by the responding station based on the sounding PPDU. If the sounding PPDU is received via a plurality of contiguous channels, the beamforming feedback matrix is estimated based on all of the plurality of contiguous channels. If the sounding PPDU is received via at least one of a plurality of non-contiguous channels, the beamforming feedback matrix is estimated based on only one of the plurality of non-contiguous channels.
