    摘要: The present invention relates to receiving control information in an orthogonal frequency division multiplexing (OFDM) system of a mobile communication system. The present invention includes receiving information related to a number of OFDM symbols in a subframe for receiving first control information, receiving information related to a number of OFDM symbols in the subframe for receiving second control information, decoding the first control information according to the received information related to the number of OFDM symbols in the subframe for receiving the first control information, and decoding the second control information according to the received information related to the number of OFDM symbols in the subframe for receiving the second control information, wherein the number of OFDM symbols for receiving the first control information is less than or equal to the number of OFDM symbols for receiving the second control information.

    摘要: 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.

    摘要: A method for transmitting signals using a hybrid automatic repeat request (HARQ) scheme to guarantee a constellation rearrangement gain having a predetermined level or more is provided. Predetermined code blocks are encoded, sub-block interleaving is performed with respect to the encoded code blocks, and the sub-block interleaved code blocks are transmitted according to redundancy version (RV) start locations of the sub-block interleaved code blocks. The RVs are set such that the order of bit streams modulated by an M-QAM (M>4) scheme is changed upon a retransmission. In addition, the RVs are set such that the RV start locations applied to code blocks having different sizes are different.
