Abstract: A method for detecting signals based on despreading and a signal transmitting method for the same are disclosed. Signals are spread according to the size of at least one spreading band, which is determined in consideration of a correlation degree of a frequency band in a communication system. A reception side which receives the signals detects the signals after despreading with respect to signals which are spread in a frequency band having a correlation degree equal to or greater than a predetermined level as a spreading band, among the reception signals. Thus, the dimension of the detected signals can be decreased.

Abstract: A method for efficiently transmitting downlink control information is described. A method for transmitting control information in a multiple antenna system which can simultaneously transmit a maximum of two codewords includes transmitting modulation and coding scheme (MCS) information, a new data indicator (NDI) and a redundancy version (RV) for information blocks transmitted through the two codewords, and transmitting additional control information including at least one of a swapping indicator and enable/disable information. The swapping indicator indicates whether or not swapping occurs between the information blocks transmitted through the two codewords, and the enable/disable information indicates whether or not any one of transmissions through the two codewords is disabled. The swapping indicator is reserved when any one of transmissions through the two codewords is disabled, thereby reducing signaling overhead and efficiently transmitting necessary information.
