    • The present invention relates to a method in an RBS of a wireless network, for supporting HO of a UE in a served cell. The method comprises pre-allocating resources for HO of the UE to a target cell candidate. The pre-allocated resources comprise a dedicated preamble for the target cell candidate. The method also comprises receiving a measurement report from the UE triggering a HO and comprising a list of neighbor cells, determining if a cell in the list of neighbor cells corresponds to one of the at least one target cell candidates, and when they correspond transmitting a HO command to the UE comprising the dedicated preamble for the target. The present invention also relates to a corresponding method in the target RBS and to the serving and target RBS themselves.
    • 本发明涉及无线网络的RBS中的方法,用于支持服务小区中的UE的HO。 该方法包括将UE的HO的资源预分配给目标小区候选。 预先分配的资源包括用于目标小区候选的专用前导码。 该方法还包括接收来自UE的测量报告触发HO并且包括相邻小区的列表,确定相邻小区列表中的小区是否对应于至少一个目标小区候选中的一个,并且当它们对应于发送 HO命令,包括用于目标的专用前置码。 本发明还涉及目标RBS和服务和目标RBS本身中的相应​​方法。
