Abstract:
1. A method for transmitting control channel data using time-frequency resources in a mobile communication system employing repetition coding, the method comprising: performing the repetition coding on the control channel data in order to output a plurality of encoded control channel data at a base station; and transmitting the plurality of encoded control channel data using the time-frequency resources, wherein the time-frequency resources are defined by a plurality of orthogonal frequency division multiplexing (OFDM) symbols in a time domain and a plurality of subcarriers in a frequency domain, wherein the plurality of encoded control channel data are transmitted separate from each other in the frequency domain when one of the plurality of OFDM symbols is used for transmitting, and wherein at least two of the plurality of encoded control channel data are transmitted using one of the plurality of OFDM symbols and the at least two of the plurality of encoded control channel data are transmitted separate from each other in the frequency domain when two of the plurality of OFDM symbols are used for transmitting.
