Method for transmitting uplink signals

Abstract

A method for transmitting uplink signals comprises multiplexing data and first type control information to output multiplexed signals; mapping the multiplexed signals to a resource region matrix; mapping second type control information to the resource region matrix to overwrite some of the multiplexed signals mapped to specific positions of the resource region matrix corresponding to symbols which are near symbols used for reference signals; and transmitting an output sequence of the resource region matrix to the base station. The second type control information comprises at least one of an ACK/NACK information and a rank indicator (RI), and the first type control information comprises control information other than the rank indicator (RI) and the ACK/NACK information.
