Problems solved by technology

[0005] However, the FFR scheme is suitable for a horizontal cell layout in which cells of similar size are consecutively located laterally in the layout, but it is difficult to apply the FFR scheme to a hierarchical cell structure in which a hierarchical cell structure includes one macrocell within the coverage of one macrocell or multiple picocells

Abstract

An apparatus and a method of a macro terminal for controlling interference in a wireless communication system of a hierarchical cell structure are provided. The method includes setting measurement reporting configuration for a blanking trigger per measurement identifier allocated by a macro base station, measuring a receive signal strength of a neighbor base station, comparing the measured receive signal strength value with a reference receive signal strength value of the measurement reporting configuration for the blanking trigger, and according to a comparison result, transmitting to the macro base station, a measurement report message comprising a measurement identifier corresponding to the measurement reporting configuration for the blanking trigger of a pico base station.

Description

Technical field [0001] The present invention relates to a device and method for controlling interference between base stations in a wireless communication system with a hierarchical cell structure. More specifically, the present invention relates to an apparatus and method for allocating frequency bands to minimize the interference imposed by the pico cell to the macro cell when the pico cell exists in the coverage of the macro cell. Background technique [0002] Recently, the concept of pico cells has been proposed to solve the propagation shadow area caused by the movement of the terminal between the base stations or the poor channel state between the base station and the terminal, and provide advanced technology in the cellular wireless communication system. data service. Compared with a macro cell, a pico cell covers a smaller area, and multiple pico cells may exist in the cell coverage of a macro cell. [0003] The macro cell and the pico cell can use different frequency ban...
