Abstract In relay-aided systems, the available data rate of a relay link user is determined by the minimum rate of the first hop link and the second hop link. Separate resource allocation in two-hop links may deteriorate system performance・ Therefore, based on the throughput balance, a forward allocation (FA) algorithm and a backward allocation (BA) algorithm are proposed・ In FA algorithm, resource allocation in the first hop greatly affects that of the second hop. In BA algorithm, resource allocati
