Abstract: A method for wireless communication between user equipments (UEs) and a base station in a wireless communication system that supports a first UE using a single band and a second UE using multiple bands is provided. In the method, UE receives, from the base station, resource allocation information including information regarding a downlink component carrier (CC) and an uplink CC allocated to the UE, receives the allocated downlink CC, and transmits the allocated uplink CC by applying a cell ID thereto. The allocated downlink CC is one of downlink CCs to which different cell IDs are applied, pairs of CCs are predefined by associating uplink CCs respectively with downlink CCs in order to support the first UE. When the allocated downlink and uplink CCs do not belong to the pairs of CCs, the applied cell ID is a cell ID of a downlink CC that is paired with the allocated uplink CC in the predefined pairs of CCs.

Abstract: A channel coding method of variable length information using block code is disclosed. 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 an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of minimum Hamming distance.
