Abstract
A method and system for assigning subcarrier frequency resource for a relay enhanced cellular communication system including a base station, one or more mobile stations and one or more relay stations, is provided. Subcarrier assignment involves allocating subcarriers to one or more relay communication links between the base station and relay stations, to accommodate minimum data rate requirements of the access communication links; and allocating subcarriers to one or more access communication links between relay stations and mobile stations to approximate the data rates achieved on the corresponding relay communication links, wherein allocating subcarriers to one or more access communication links includes reusing subcarriers among access communication links in different relay cells.
