Abstract: A method and wireless station for receiving signals. The wireless station receives, from a base station, a control signal on a first subframe indicated as a downlink (DL) subframe by a time division duplex (TDD) uplink-downlink (UL-DL) subframe configuration. The control signal includes first information indicating that at least one UL subframe indicated by the TDD UL-DL subframe configuration is reconfigured as a TDD DL subframe. The wireless station receives, from the base station, DL data on a second subframe which was indicated as a TDD UL subframe by the TDD UL-DL subframe configuration but is currently reconfigured as a TDD DL subframe by the control signal. The wireless station transmits, to the base station, UL data on a TDD UL subframe except for being reconfigured as the TDD DL subframe by the control signal.

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 communication method that includes transmitting a power save multi-poll (PSMP) frame containing a power save mode (PSM) of a non-access point (AP) station (STA) to a first station and to a second station which are paired with an AP on the basis of multiple input multiple output (MIMO) technology. Information on the PSM indicates the point in time of starting a downlink transmission period, the duration of the downlink transmission period, and transmission object station identification information. The method further involves transmitting a data frame to the first station and to the second station on the basis of the MIMO technology during the downlink transmission period. The transmission object station identification information indicates a group identifier for indicating an object station group including the first station and the second station.

Abstract: A method is provided for communications between a responding station and a requesting station. In a wireless local area network, the responding station receives a null data packet announcement (NDPA) frame and a null data packet (NDP) frame for channel sounding, and a first poll frame, from the requesting station. The NDP frame follows the NDPA frame. In response to the first poll frame, the responding station transmits a first feedback data field including beamforming feedback information and signal to noise ratio (SNR) information to the requesting station. The responding station receives a second poll frame including a segment retransmission bitmap field indicating at least one segment of the first feedback data field from the requesting station. In response to the second poll frame, the responding station transmits a second feedback data field including the at least one segment of the first feedback data field to the requesting station.
