Abstract: This paper proposes a new packet scheduling algorithm for multi-service scenarios on High Speed Downlink Packet Access (HSDPA). This packet scheduling algorithm consideres both the delay constraint and the fairness for each traffic class while guaranteeing different quality of service (QoS) for each traffic class. The strategy is evaluated in a scenario including steaming and interactive and background traffic. Numerical simulation results show that system performance can be more significantly improves employing this algorithm than that with PF or M-LWDF method.
