摘要：
This paper proposes a handover scheme using uplink and downlink channel quality information in order to improve the uplink channel performance during a handover process. The proposed scheme has two main features. First, the proposed scheme adopts the scanning process without an association process in order to obtain an uplink channel quality. Second, it designs the handover triggering and decision criteria using an uplink and downlink channel quality in order to reduce the call outage probability of an uplink channel. Simulation results show that the proposed scheme can reduce the call outage probability by 33%. In addition, it also promotes the percentage of users who satisfy the Quality of Service(QoS) requirement for a handover from 83% to 89%.
