摘要:
The present disclosure provides a method (100) in a wireless device for initiating a handover from a source base station to a target base station. The method includes the steps of: calculating (S110) a power offset indicative of a difference between a receiving power from the target base station and a receiving power from the source base station; obtaining (S120) a Time Division Duplex (TDD) configuration difference between a TDD configuration of the target base station and a TDD configuration of the source base station; calculating (S130) a TDD offset based on the TDD configuration difference and an uplink-downlink traffic model of the wireless device; and initiating (S140) the handover when a combination of the power offset and the TDD offset exceeds a threshold. The present disclosure also provides a wireless device (600), a method (700) in a base station and a base station (800).
摘要(中):
本公开提供了一种用于发起从源基站到目标基站的切换的无线设备中的方法(100)。 该方法包括以下步骤:计算(S110)指示来自目标基站的接收功率与来自源基站的接收功率之间的差异的功率偏移; 获取(S120)目标基站的TDD配置与源基站的TDD配置之间的时分双工(TDD)配置差异; 基于所述TDD配置差和所述无线设备的上行链路 - 下行链路业务模型来计算(S130)TDD偏移; 以及当功率偏移和TDD偏移的组合超过阈值时发起(S140)切换。 本公开还提供了一种无线设备(600),基站中的方法(700)和基站(800)。
