Abstract

Recently, many channel-dependent scheduling schemes for high speed downlink packet access (HSDPA) system have been introduced to provide high system throughput and quality-of-service (QoS) guarantee. However, no work has considered hybrid automatic repeat request (HARQ), one of special features of Universal Mobile Telecommunications System (UMTS) Release 5 network. In this paper, a new packet scheduling algorithm which suspends HARQ process is proposed. The performance of the proposed scheme is compared with normal HARQ mode with max CIR and PF algorithms in fast fading channels. Results from system-level simulation show that with the proposed algorithm average cell throughput can be increased with no degradation of QoS.
