摘　　要：接力切换是TD-SCDMA移动通信系统的核心技术之一。本文提出可提高新RL的发射功率、保证UE在切换区域接收到目标小区发送的用户数据、同时可避免对其他UE造成干扰的接力切换中目标小区用户数据发送点的优化选择方法。Baton Handover is one of the core technologies of TD-SCDMA mobile communication system. This article proposes an optimized method for selecting user data transmission points in target cell during Baton Handover, which can enhance the transmission power of new RL, guarantee the user data transmitted by target cell can be received by UE in handover area, and avoid interference on other UE.

关 键 词：接力切换 TD-SCDMA 数据发送点
