    摘要: A method and apparatus of transmitting a reference signal in a wireless communication system is provided. A reference signal sequence is generated by using a pseudo-random sequence. A portion or entirety of the reference signal sequence is mapped to at least one resource block and is transmitted. The pseudo-random sequence is generated by a gold sequence generator which is initialized with initial values obtained by using cell identifier. The reference signal provides low PAPR and high cross correlation characteristic.

    摘要: A method for efficiently transmitting and receiving control information through a Physical Downlink Control Channel (PDCCH) is provided. When a User Equipment (UE) receives control information through a PDCCH, the received control information is set to be decoded in units of search spaces, each having a specific start position in the specific subframe. Here, a modulo operation according to a predetermined first constant value (D) is performed on an input value to calculate a first result value, and a modulo operation according to a predetermined first variable value (C) corresponding to the number of candidate start positions that can be used as the specific start position is performed on the calculated first result value to calculate a second result value and an index position corresponding to the second result value is used as the specific start position. Transmitting control information in this manner enables a plurality of UEs to efficiently receive PDCCHs without collisions.

    摘要: A method for receiving an acknowledgement (ACK)/negative acknowledgement (NAK) signal in an orthogonal frequency division multiplexing (OFDM) communication system is described. The method includes receiving ACK/NAK signals and repetitions of the ACK/NAK signals mapped to one or more OFDM symbols which are allocated for transmission of a plurality of ACK/NAK signals within one sub-frame, and confirming receipt of the ACK/NAK signals. The OFDM symbol for each ACK/NAK signal is determined according to the repetition of the ACK/NAK signals, and frequency regions for the ACK/NAK signals within the OFDM symbols are different from frequency regions for the repetition of the ACK/NAK signals within the OFDM symbols.
