<P>PROBLEM TO BE SOLVED: To provide techniques for sending control information in a wireless communication system. <P>SOLUTION: A UE spreads control information across frequency with a DFT and across time with an orthogonal sequence. The UE receives codewords for N HARQ processes in N subframes, determines an ACK value for each HARQ process, codes N ACK values for the N HARQ processes to obtain ACK information, determines output data for the ACK information, and sends the output data in one of M uplink subframes. First control information is processed based on a first coding and multiplexing scheme utilizing code division multiplexing in the time and frequency domains. Second control information is processed based on a second coding and multiplexing scheme utilizing code division multiplexing in the time domain and spreading in the frequency domain. <P>COPYRIGHT: (C)2013,JPO&INPIT |
