A method for transmitting signal, at a mobile station, in a wireless communication system is provided. Inter-cell interference information may be different for each frequency partition according to using a FFR scheme. Also, a parameter for controlling interference level between base stations may be different for each frequency partition. The present invention is advantageous in that, when uplink transmission is performed, system throughput and cell edge-user throughput are improved and inter-cell interference level control is efficiently performed.

The present invention relates to a segment identifier detection method performed by a terminal if a segment being administrated by a base station in a wireless communication system has the frequency reuse factor of 3 and 2 at the same time. In particular, the method comprises: acquiring a cell identifier and a segment identifier corresponding to the cell identifier from a secondary advanced preamble (SA-preamble) that has been received from the base station; determining a frequency reuse factor of the base station; and if the frequency reuse factor is 2 and the obtained segment identifier is a third segment identifier, transforming the segment identifier corresponding to the cell identifier into a first segment identifier or a second segment identifier.

A method for transmitting signal, at a mobile station, in a wireless communication system is provided. Inter-cell interference level control parameter information may be different for each frequency partition due to use of an FFR scheme. This method is advantageous in that, when uplink transmission is performed, system throughput and cell edge-user throughput are improved and inter-cell interference level control is efficiently performed, thereby improving a Signal to Interference plus Noise Ratio (SINR) at the receiving end.

The present invention relates to a method for transmitting and receiving data in a wireless communication system. The method for transmitting data in a wireless communication system, according to one aspect of the present invention, comprises a step in which a base station transmits downlink data to a first terminal which supports a first system via a first region of a frame, and transmits downlink data to a second terminal which supports a second system via a second region which follows the first region corresponding to a frame offset on a time axis, wherein said frame offset is an offset of the start point of the frame for said first system and the start point of the frame for said second system, and said first region includes 3+6 (said frame offset-1) OFDM symbols.
