Method for transmitting uplink signals

摘要

A method for transmitting uplink signals, which include ACK/NACK signals, control signals other than the ACK/NACK signals, and data signals, is disclosed. The method comprises serially multiplexing the control signals and the data signals; sequentially mapping the multiplexed signals within a specific resource region in accordance with a time-first mapping method, the specific resource region including a plurality of symbols and a plurality of virtual subcarriers; and arranging the ACK/NACK signals at both symbols near symbols to which a reference signal of the plurality of symbols is transmitted. Thus, the uplink signals can be transmitted to improve receiving reliability of signals having high priority.

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.
