Abstract: In order to solve resource allocation problem in heterogeneous system with Delay-Constrained (DC) users and No-Delay-Constrained (NDC) users, under the power constraints for base station and relay stations to guarantee data rates for DC users and with the maximization of the sum-rate of NCD users, an adaptive allocation algorithm is proposed. In the subcarrier allocation, both subcarrier matching and non-matching of two-hop relay links are considered. In the power allocation, optimal power allocation is obtained. Simulation results show that the proposed resource allocation algorithm has better performance with lower computation complexity.

Key words: information processing, resource allocation, relay-assisted communication systems, delay constrain, non-delay constrain
