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 of transmitting information on a modulation and coding scheme (MCS) in a wireless local area network system is provided. A responding station receives a physical layer protocol data unit (PPDU) from a requesting station, configures a MCS feedback (MFB) based on the PPDU, and transmits feedback information to the requesting station. If the MFB is configured as a response to a MFB request (MRQ) of the requesting station, the feedback information includes the configured MFB and a MFB type field indicating that the MFB is configured as a response to the MRQ of the requesting station. If the MFB is not configured as a response to the MRQ of the requesting station, the feedback information includes the configured MFB, a MFB type field indicating that the MFB is not configured as a response to the MRQ of the requesting station, and coding information indicating a PPDU coding type.
