| 摘 要： | 提出了一种基于半静态干扰协调的支持多业务QoS的OFDMA资源分配算法PQSIC。算法按信道质量将用户分为中心和边缘用户,综合考虑业务的QoS要求和边缘用户的信道质量,在特定的频率资源规划方案基础上确定小区中心、边缘用户的可用频率资源,然后将其可用频率资源分别在小区中心和边缘用户中进行分配。仿真结果表明:PQSIC算法能合理分配频率资源,较好地保证多业务系统中用户的QoS。

| Abstract: | In order to meet multi-service's QoS requirement of multi-service OFDMA cellular system,a resource allocation algorithm based on semi-static interference coordination (PQSIC) was proposed.Users were divided into cell-inner user and cell-edge user according to channel quality in systems.Taking services' QoS and channel quality of cell-edge user into account,the proposed algorithm figured out the available frequency resource of cell-inner and cell-edge user based on a unique frequency resource priority scheme.The simulation results show that through reasonable frequency resource allocation,PQSIC can preferably guarantee QoS in multi-service system. |
