Multi-QoS scheduling algorithm for class fairness in high speed downlink packet access

Abstract

Since there are various packet-type services with different QoS's , a scheduling algorithm that can support multiple QoS classes is needed to efficiently provide data services in the high speed downlink packet access (HSDPA). In this paper, we investigate the capability of HSDPA to support multiple QoS classes and propose an improved scheduling algorithm to serve multiple QoS classes
