支持多业务QoS的多小区OFDMA资源分配算法

In this paper 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.
