摘要：
In this letter we investigated the packet transmission control in downlink CDMA cellular systems. The downlink packet transmission control scheme based on the soft handoff status was proposed to enhance the system performance. The proposed scheme controls the downlink packet transmissions by employing a transmission window which is individually resolved to each mobile station according to its propagation condition and soft handoff status. Computer simulation shows that compared with the conventional scheme the proposed scheme improved the delay performance and fairness of service in packet reception.
