METHOD FOR MAPPING DATA, METHOD FOR DECODING DATA AND METHOD FOR TRANSMITTING CONTROL CHANNEL

摘要

A method for mapping data, a method for decoding data, and a method for transmitting a control channel are provided to enhance data receiving performance even when a transmitter and a receiver share information about mapping rules. A method for transmitting a control channel comprises the following steps of: determining a control channel transmission OFDM(Orthogonal Frequency Division Multiplexing) symbol(S10); determining a control channel transmission sub-carrier in consideration of the determined control channel transmission OFDM symbol(S11); broadcasting information about the control channel transmission OFDM symbol to receivers(S12); and transmitting the control channel by using the determined control channel transmission OFDM symbol and sub-carrier after determining the control channel transmission OFDM symbol and sub-carrier(S13).
