    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.

    Abstract: A method and terminal apparatus are described for performing channel interleaving at a terminal in a multiple-input multiple-output (MIMO) wireless communication system. A number of columns C of an interleaver matrix are assigned as a number of symbols for transmitting data per subframe (Nsymb). A number of rows R of the interleaver matrix is defined as H · L · log 2   Q C , where H is a number of modulation symbols per layer, L is a number of layers and Q is a modulation order. Input vector sequences are written into entries of the interleaver matrix, row by row. Each of the entries has a size of L·log2Q bits. Output bit sequences are generated by reading out the entries of the interleaver matrix, column by column. The output bit sequences are modulated by a unit of log2Q bits, to generate modulation symbols. The modulation symbols are mapped to the L layers, and transmitted by using the L layers.
