Abstract: A method and apparatus for transmitting and receiving system information in a wireless communication system are disclosed. A method for receiving system information by a mobile station (MS) of a wireless communication system includes receiving a secondary superframe header (S-SFH) change cycle from a base station (BS), and receiving a primary superframe header information element (P-SFH IE) including a first field indicating a change count of a plurality of secondary superframe header subpacket information elements (S-SFH SP IEs) from the base station (BS). Once each of the plurality of S-SFH SP IEs is changed, each of the plurality of S-SFH SP IEs remains unchanged during one or more S-SFH change cycles.

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.
