    摘要: Disclosed is a communication method in a multi-carrier system, including: allocating radio resources for transmitting signals to a middle guard band; and transmitting the signals through the radio resources; wherein the middle guard band is a frequency band positioned between used bands of a plurality of carriers, respectively, within an aggregated carrier formed by aggregating the plurality of carriers and a unit allocating the radio resources of the middle guard band is different from a unit allocating the radio resources of the used bands. A multi-carrier system uses the guard bands between the carriers to improve channel estimation performance or increase efficiency of radio resources.

    摘要: The present invention relates to a method for a terminal for transmitting an uplink control signal, i.e., an ACK/NACK (Acknowledgement/Negative-ACK) signal, in a wireless communication system. In particular, the method comprises: mapping part of the ACK/NACK signals to selection information, which is composed of a combination of message areas and reference signal areas; independently selecting one message area and one reference signal from a plurality of control channel resources that are located in the same resource block, based on the mapped selection information; allocating the selected message area to the other ACK/NACK signals; and transmitting the ACK/NACK signal to a base station by using the selected message area and the selected reference signal area.

A terminal receives a plurality of transmission blocks through a plurality of downlink component carrier waves, and determines a plurality of ACK/NACK resources for the plurality of transmission blocks. If the plurality of ACK/NACK resources overlaps, the terminal uses the overlapping ACK/NACK resources to transmit one bundled ACK/NACK signal for the plurality of transmission blocks through an uplink component carrier wave.
