Abstract: A method is provided for transmitting data in a wireless local area network. A transmitter generates an encoded data unit by performing a channel coding to transmission data to be included in a data field of a physical layer protocol data unit (PPDU). The transmitter generates at least one spatial block by re-arranging the encoded data unit, and divides each spatial block of at least one spatial block into two frequency segments. A bandwidth of each frequency segment is half of a bandwidth of the each spatial block. The transmitter interleaves the two frequency segments to generate a first interleaved segment and a second interleaved segment, respectively, and generates first and second mapped sequences by respectively mapping the first and second interleaved segments into a signal constellation. The transmitter performs an Inverse Discrete Fourier Transform (IDFT) on the first and second mapped sequences to generate and transmit a transmission signal.

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.
