Method for transmitting uplink signals
First Claim
1. A method for transmitting signals including ACK/NACK signals, control signals other than the ACK/NACK signals, and data signals in a mobile communication system, the method comprising:
- mapping reference signals on predetermined time domain units corresponding to first specific symbols of a two-dimensional resource region comprising a plurality of symbols, wherein the two-dimensional resource region comprises plural time domain units in a first dimension and plural frequency domain units in a second dimension;
serially multiplexing the control signals other than the ACK/NACK signals and the data signals;
mapping the serially multiplexed signals to the two-dimensional resource region;
mapping said ACK/NACK signals to second specific symbols adjacent to said first specific symbols by overwriting a part of said multiplexed signals mapped to the second specific symbols; and
transmitting the reference signals, ACK/NACK signals, control signals other than ACK/NACK signals, and data signals mapped to the resource region.

Abstract
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.
