Abstract
A method for transmitting information that supports a legacy system and a multi-carrier system is disclosed. The method for transmitting information supporting a legacy system includes constructing a frame structure for supporting the legacy system, and transmitting a frame header including allocation information of the frame structure to a mobile station.
Claims11
A method for transmitting information supporting a legacy system, the method comprising:
- constructing, by a base station, a frame structure for supporting the legacy system;
- and
- transmitting, from the base station to a mobile terminal, allocation information of the frame structure via a broadcast channel (BCH) of a frame header,
- wherein the allocation information includes a first indicator for indicating whether a base station supports the legacy system, first information for indicating a ratio of first sub-frames supporting the legacy system among downlink and uplink sub-frames, bandwidth information of the first sub-frames, a second indicator for indicating multiplexing information of uplink sub-frames from among the first sub-frames, and second information about a center frequency of the first sub-frames.

A method for receiving information supporting a legacy system, the method comprising:
- receiving, by a mobile station, a frame header including allocation information of a frame supporting the legacy system from a base station;
- and
- receiving, by the mobile station, a control message through a region supporting the legacy system indicated by the frame header,
- wherein the allocation information is transmitted through a secondary broadcast channel (SBCH) contained in the frame header, and
- wherein the allocation information includes a first indicator for indicating whether a base station supports the legacy system, first information for indicating a ratio of first sub-frames supporting the legacy system among downlink and uplink sub-frames, bandwidth information of the first sub-frames, a second indicator for indicating multiplexing information of uplink sub-frames from among the first sub-frames, and second information about a center frequency of the first sub-frames.
