    摘要: 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 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.
