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.

Abstract: A method is provided for transmitting a data frame by a station in a wireless local area network. The station obtains a transmission opportunity (TXOP) for a bandwidth, the TXOP indicating an interval of time during which the station has a right to initiate frame exchange sequences onto wireless medium. The station sets a transmit bandwidth parameter of a non-initial physical layer protocol data unit (PPDU) of a plurality of PPDUs to be transmitted during the TXOP based on a transmit bandwidth parameter of a preceding PPDU of the plurality of PPDUs. The transmit bandwidth parameter of the non-initial PPDU is set to be same or narrower than the transmit bandwidth parameter of the preceding PPDU. A bandwidth indicated by the transmit bandwidth parameter of the non-initial PPDU or the preceding PPDU includes at least one of 20 MHz, 40 MHz and 80 MHz. The station transmits the non-initial PPDU during the TXOP.
