Abstract: According to one aspect of the present invention, values which are specifically defined for each user equipment are reflected when resource allocation/mapping of downlink/uplink ACK/NACK channels is performed, so as to vary uplink/downlink ACK/NACK information transmitting resources for each user equipment allocated to the same downlink/uplink resource. According to another aspect of the present invention, nodes for transmitting uplink/downlink ACK/NACK information vary for each user equipment allocated to the same downlink/uplink resource. According to the present invention, even when downlink/uplink signals for a plurality of user equipment are transmitted from the same resource, uplink/downlink ACK/NACK signals of the plurality of user equipment are transmitted from different resources, thereby reducing interferences among ACK/NACK signals of the plurality of user equipment.

Abstract: A method of transmitting and receiving data using a superframe structure is disclosed. A method for transmitting data through a superframe including a superframe header, includes generating the superframe which includes a data region including user data and includes a dedicated control region including data region allocation information indicating resource allocation for the data region, and transmitting the superframe. The dedicated control region is arranged at at least one of locations except for a subframe of the superframe header. A user equipment which does not have to transmit and receive data decodes only data region allocation information using information of the data region indicated by a dedicated control region, thereby minimizing power loss, reducing a feedback delay, and reducing system overhead using a superframe structure.
