    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 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.

    摘要: There are provided a method and apparatus for allocating a sounding channel in a wireless communication system. A base station transmits a first sounding channel allocation data to allocate a first sounding channel for a first system to a first zone, and transmits a second sounding channel allocation data to allocate a second sounding channel for a second system other than the first system to a second zone. The first zone and the second zone are multiplexed by an FDM (Frequency Division Multiplexing) method, and the first sounding channel and the second sounding channel are allocated to a same OFDMA (Orthogonal Frequency Division Multiple Access) symbol. A channel response can be estimated accurately when a terminal for IEEE (Institute of Electrical and Electronics Engineers) 802.16m system and a terminal for IEEE 802.16e system coexist in a legacy support mode.

    摘要: A method of transmitting data in a wireless communication system includes preparing a frame including a unicast subframe for unicast data and an MBS (Multicast and Broadcast Service) subframe for MBS data; and transmitting the unicast data and the MBS data via the frame, wherein the MBS subframe includes an idle time during which data is not carried, and the idle time is arranged to be at the temporally latest position in the MBS subframe. An MBS frame structure for using an appropriate CP with respect to MBS signals transmitted from multi-cell is provided, so an unnecessary idle time can be reduced, and thus, the efficiency of limited radio resources can be improved.
