Problems solved by technology

Actually, however, since the orthogonal property is not perfect due to a multi-path phenomenon, a Doppler effect, etc. existing in the wireless channel environment, interference may occur between the control channels.
In addition, it is general that the orthogonality is not satisfied between the time and code resources used between different cells, causing occurrence of interf

Abstract

A method for transmitting an uplink control channel at a terminal in a Single Carrier Frequency Division Multiple Access (SC-FDMA)-based mobile communication system is provided. The transmission method includes receiving a control channel index allocated from a base station; transmitting control information at every symbol through a subband and a Zadoff-Chue sequence offset resource, which are mapped to the control channel index according to a first grouping rule; and transmitting control information through a subband and a Zadoff-Chue sequence offset resource, which are mapped to the control channel index according to a second grouping rule, beginning from a symbol after a slot boundary.
