    Abstract: According to one embodiment, a method for a wireless local area includes: generating a medium access control (MAC) protocol data unit (MPDU) to be transmitted to a target station; generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) by attaching a PLCP preamble to the MPDU; selecting a transmission channel; and transmitting the PPDU to the target station over the transmission channel. 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.
