METHOD AND APPARATUS FOR REUSE OF ADAPTIVE PARTIAL FREQUENCY IN A CELLULAR MOBILE COMMUNICATION SYSTEM

摘要

A method according to an embodiment of the present invention is an adaptive partial frequency reuse method in a mobile communication system including one or more base stations using the same frequency band and a central controller for integrally controlling the one or more base stations, The method comprising the steps of: dividing the frequency band into a plurality of subbands; determining whether a UE located at a cell boundary exists using the interference feedback information; Allocating a different power to each of the plurality of subbands for each of the plurality of subbands when there is a terminal located at the cell boundary; Allocating the same power to each of the plurality of subbands; and performing a data service to the terminal with the power allocated to each of the plurality of subbands, wherein the step of determining whether or not a terminal located at the cell boundary exists, A channel quality indicator value of a serving cell transmitted from the UE is compared with a channel quality indicator value of each neighbor cell, and if the difference is less than a predetermined threshold value, the UE determines that the boundary of the corresponding cell is located.
