摘要The 3rd generation WCDMA standard has been enhanced to offer significantly increased performance for packet data. But coming application like multimedia on desiring data rates will spur the UMTS can support. To support for such high data rates, high speed downlink access (HSDPA), labeled as a 3.5G wireless system , has been published in UMTS Release05. Under the HSDPA system, have to support high speed transmission and promises a peak data rate of up to 10 Mb/s. To achieve such high speed rate, system provides the channel quality indicator (CQI) information to detect the air interface condition. Then, there are many channel condition related scheduling schemes have been proposed to attend achievement of high system performance and guarantee the quality-of-service (QoS) requirements. However, there is no solution of packet scheduling algorithm can consider differences of data-types priority management under the hybrid automatic repeat (H-ARQ) scenario. In this paper, we propose the weight combination packet scheduling algorithm to target to enhance the system efficiency and balanced QoS requirements. The proposed schemes is simulated with OPNET simulator and compared with the Max CIR and PF algorithms in fast fading channel. Simulation result shows that the proposed algorithm can both effectively increase the cell throughput and meet userpsilas satisfaction base on QoS requirements.
