Abstract: A method is provided for performing, by a first device, channel coding of data to be transmitted to a second device. The first device determines a size of a transport block for the data, attaches a first cyclic redundancy check (CRC) code to the transport block having the determined size to produce a first CRC-attached transport block, and segments the first CRC-attached transport block into multiple code blocks when a size of the first CRC-attached transport block is larger than a predetermined size. The size of the transport block is determined from among a plurality of predetermined transport block sizes, and the plurality of predetermined transport block sizes are predetermined such that all the multiple code blocks have a same size as each other.

Abstract: A method for adaptively allocating resources of an uplink control channel according to a system situation is disclosed. If a base station (BS) recognizes the system situation, establishes control information for resource allocation, and transmits the control information to a mobile station (MS), the mobile station (MS) allocates resources for transmitting uplink control information using a specific block or a specific resource distribution method according to the corresponding control information. The system situation may be changed according to the number of users contained in the BS's coverage or the usage of a multi-antenna. The variation of the system situation is actively reflected so that the uplink channel resources can be effectively used.
