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.

Abstract: A method is provided for transmitting a signal by a station in a wireless local area network (WLAN). The station obtains a transmission opportunity (TXOP) indicating a time duration used for transmission of a plurality of data units. The station transmits, during the TXOP, an initial data unit of the plurality of data units. The initial data unit comprises a control field indicating a transmit bandwidth of the initial data unit. The station selects a transmit bandwidth of a non-initial data unit of the plurality of data units to be narrower than the transmit bandwidth of the initial data unit. The station transmits, during the TXOP, the non-initial data unit. The non-initial data unit comprises a control field indicating the transmit bandwidth of the non-initial data unit.

Abstract: A method and apparatus are described for transmitting a channel state information (CSI) reporting at a user equipment (UE) in a wireless communication system. A rank indicator (RI) and a first type precoding matrix indicator (PMI) are transmitted to a base station (BS) according to a first CSI feedback type. A second type PMI and a channel quality information (CQI) are transmitted to the BS according to a second CSI feedback type. The RI and the first type PMI are jointly coded, and transmitted through a physical uplink control channel (PUCCH). A reporting period of the first type PMI is longer than a reporting period of the second type PMI. The first type PMI is a wideband PMI, and the second type PMI is a subband PMI. The reporting period of the first type PMI is equal to a reporting period of the RI.

Abstract: A method for transmitting information of resources for use in transmission of ACK/NACK signals in a mobile communication system is disclosed. An example method for receiving ACK/NACK signals in a mobile communication system is also disclosed. When resources for transmission of data and resources for transmission of control information of the data are scheduled through virtual unit resources, the method identifies information of resources for receiving an ACK/NACK signal for transmission data mapped to information of at least one of a virtual unit resource allocated to the transmission data and a virtual unit resource allocated to control information of the transmission data, and receives the ACK/NACK signal for the transmission data through the information of resources for receiving the ACK/NACK signal.
