摘要： 针对同时包含有时延约束(DC)用户和没有时延约束(NDC)用户的异构系统资源分配问题,在基站和中继站功率分别约束的条件下,为保证DC用户的固定数据速率,同时最大化NDC用户的总数据速率,提出了一种自适应资源分配算法。该算法在子载波分配过程中,考虑了两跳中继链路子载波配对和不配对两种情况,在功率分配过程中,实现了最优功率分配。仿真结果表明,本文提出的资源分配算法可以在较低计算复杂度下取得良好性能。

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
