Abstract: A symbol mapping method for repetition coding is disclosed. The symbol mapping method comprises performing repetition coding on codeword to output repeated codeword symbols, and mapping the repeated codeword symbols with subcarriers located in different localized resource blocks. According to the embodiments of the present invention, it is possible to obtain maximum reliability in a receiving side by mapping codeword bits with subcarriers to reduce the number of bits having low reliability when a transmitting side uses repetition coding. Also, it is possible to improve decoding throughput and obtain channel diversity.

Abstract: Repetition coding is performed on control channel information to generate a plurality of encoded control channel signals, which are then transmitted using time-frequency resource-element groups. The time-frequency resource-element groups include orthogonal frequency division multiplexing (OFDM) symbols in a time domain and frequency subcarriers in a frequency domain. The plurality of encoded control channel signals are transmitted separately from each other in the frequency domain when one of the OFDM symbols is used for transmitting the plurality of encoded control channel signals. At least two of the plurality of encoded control channel signals are transmitted using one or more resource-element groups and the at least two of the plurality of encoded control channel signals are transmitted separately from each other in the frequency domain when two of the OFDM symbols are used for transmitting.
