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.

Abstract: A method is provided for transmitting a physical uplink control channel (PUCCH) in a wireless communication system supporting multiple antennas. The method is performed by a user equipment (UE) having a first antenna port and a second antenna port, and configured for using a multiple-antenna transmit mode for transmission using multiple antennas and a single-antenna transmit mode for transmission using a single antenna. The UE determines that the multiple-antenna transmit mode is to be used for transmitting the PUCCH, and determines a transmit power offset value to be added to a transmit power of the PUCCH depending on a PUCCH format to be used for transmitting the PUCCH using the first and second antenna ports. The UE transmits the PUCCH by using a first PUCCH resource through the first antenna port, and transmits the PUCCH by using a second PUCCH resource through the second antenna port.

Abstract: A method for channel-coding information bits using a code generation matrix including 32 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having “A” length using basis sequences having 32-bit length corresponding to columns of the code generation matrix, and outputting the channel-coded result as an output sequence. If “A” is higher than 10, the code generation matrix is generated when (A-10) additional basis sequences were added as column-directional sequences to a first or second matrix. The first matrix is a TFCI code generation matrix composed of 32 rows and 10 columns used for TFCI coding. The second matrix is made when at least one of an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of a minimum Hamming distance.
