    Abstract: A method for managing neighbor cell interference comprises: a step of measuring inter-cell interference control information by subframe units; and a step of transmitting the inter-cell interference control information measured by subframe units, to at least one neighbor cell for each of the subframes. The interference management method of the present invention dynamically performs neighbor cell interference management under the condition where neighbor cell interference changes in terms of time, thus improving performance of a system. Further, the interference management method of the present invention maps a wireless resource property pattern to a cell ID. Consequently, the system adopting the method of the present invention exhibits excellent performance in any environment.

    Abstract: Disclosed is a method for directly transmitting and receiving data between terminals in a frequency division duplexing (FDD)-type and time division duplexing (TDD)-type mobile communication system. For FDD-type systems, provided are methods for performing direct data transmission and reception between terminals on the basis of a downlink subframe time interval and methods for performing direct data transmission and reception between terminals on the basis of an uplink subframe time interval. For TDD-type systems, provided are methods for performing direct data transmission and reception between terminals in a downlink subframe and methods for performing direct data transmission and reception between terminals in an uplink subframe. Additionally, for each method, provided are systems for performing only reception or transmission in one subframe and systems for performing both reception and transmission in one subframe. Accordingly, when a method for directly transmitting and receiving data between terminals according to the present invention is used, direct data transmission and reception is possible between adjacent terminals without passing through a base station, such that the waste and delivery delays of a radio resource for communication between a base station and a terminal may be reduced.

    Abstract: The present invention relates to a cooperative communication method, in which a plurality of cells performs multiple antenna transmission and receiving cooperatively with each other in a cellular wireless system, and a terminal transmits channel state information (CSI) wirelessly to a serving cell and to at least one cooperative cell such that the serving cell and the cooperative cell use the CSI to perform multipoint communication. Although the serving cell and the cooperative cell may be of different base stations from each other, the transmission delay and traffic increase in a backhaul network can be prevented by minimizing information exchange between these cells.

    Abstract: The present invention relates to a transmitter in a frequency division multiple access communication system. The transmitter generates a plurality of pilot symbols, and groups the plurality of pilot symbols into a plurality of groups according to a location of a subcarrier. In addition, the transmitter inverse fast Fourier transforms the pilot symbol in each group, and sequentially outputs a first pilot symbol sequence corresponding to each group. The transmitter generates a plurality of pilot blocks respectively corresponding to the plurality of groups, and converts the first pilot symbol sequence of each group into a second pilot symbol sequence of a corresponding pilot block among the plurality of pilot blocks.
