Relay communication method for an OFDMA-based cellular communication system
First Claim
1. A relay communication method in an orthogonal frequency division multiple access (OFDMA) communication system including at least one base station for providing a multiple access service to a plurality of mobile stations frame by frame, comprising the steps of:
- dividing a cell defined by transmission power of the at least one base station into a plurality of sectors;
dividing the cell into an inner area supporting a first service and an outer area supporting a second service;
arranging at least one relay station in a second service area of each sector; and
allocating a partial resource of a frame for communication between the base station and the mobile station through the relay station.

Abstract
A relay communication method in an orthogonal frequency division multiple access (OFDMA) communication system including at least one base station for providing a multiple access service to a plurality of mobile stations frame by frame. The relay communication method includes dividing a cell defined by transmission power of the base station into a plurality of sectors on the basis of the base station; dividing the cell into an inner area where a first service is supported and an outer area where a second service is supported, on the basis of the base station; arranging at least one relay station in a second service area of each sector; and allocating a partial resource of the frame for communication between the base station and the mobile station through the relay station.
