    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 for transmitting, by a base station, configuration information for a reference signal for channel measurement. The method according to one embodiment includes transmitting, to a user equipment, first resource information for indicating a first pattern, first subframe information for indicating a first subframe, second resource information for indicating a second pattern, and second subframe information for indicating a second subframe.

Selecting the transmission channel includes: performing clear channel assessment (CCA) on a first channel to determine whether the first channel is idle; and only after it is determined that the first channel is idle, selecting the first channel and at least one idle second channel as the transmission channel. The PLCP preamble includes channel allocation information indicating a bandwidth of the transmission channel.

    Abstract: A method and terminal apparatus are described for performing channel interleaving at a terminal in a multiple-input multiple-output (MIMO) wireless communication system. A number of columns C of an interleaver matrix are assigned as a number of symbols for transmitting data per subframe (Nsymb). A number of rows R of the interleaver matrix is defined as H · L · log 2 ⁢ Q C , where H is a number of modulation symbols per layer, L is a number of layers and Q is a modulation order. Input vector sequences are written into entries of the interleaver matrix, row by row. Each of the entries has a size of L·log2 Q bits. Output bit sequences are generated by reading out the entries of the interleaver matrix, column by column. The output bit sequences are modulated by a unit of log2 Q bits, to generate modulation symbols. The modulation symbols are mapped to the L layers, and transmitted by using the L layers.
