Abstract:
1. A method for a user equipment (UE) to transmit signals to a base station, the method comprising: multiplexing data and first type control information to output multiplexed signals to be transmitted via a Physical Uplink Shared Channel (PUSCH) when the UE is to transmit the data and the first type control information simultaneously; mapping the multiplexed signals to a R×C matrix, wherein the ‘R’ is equal to the number of rows of the matrix, and the ‘C’ is equal to the number of columns of the matrix which is determined based on a number of SC-FDMA symbols within one subframe except for specific SC-FDMA symbols used for a reference signal, and wherein the multiplexed signals are row-by-row mapped to the R×C matrix; mapping second type control information to the R×C matrix to overwrite some of the multiplexed signals mapped to specific columns of the R×C matrix corresponding to SC-FDMA symbols adjacent to the specific SC-FDMA symbols; wherein, in accordance with the time-first mapping, first control signals not including the second type information are mapped to extend along specific adjacent rows of the matrix whereby the first control signals are arranged orthogonally to the specific columns; and transmitting an output sequence of the R×C matrix to the base station, wherein the output sequence is a bit sequence read out column-by-column from the R×C matrix.
