Description

目标小区的选择方法、配置方法、信息传输方法及设备
本公开要求于2022年08月30日提交中国专利局、申请号为202211049433.7、申请名称为“目标小区的选择方法、配置方法、信息传输方法及设备”的中国专利申请的优先权,其全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信技术领域,尤其是指一种目标小区的选择方法、配置方法、信息传输方法及设备。
背景技术
为了提高移动的鲁棒性和可靠性,当前技术中引入了条件切换(Conditional Handover,CHO)和条件主辅小区增加/改变(Conditional PSCell Addition/Change,CPAC),CPAC是指没有主节点(Master Node,MN)参与的辅节点(Secondary Node,SN)内的主辅小区(Primary Secondary Cell,PSCell)条件改变,并进一步引入了SN间的PSCell条件改变和条件PSCell添加。
当前技术中只支持网络侧单独为终端配置CHO或CPAC,即终端在配置CHO时只判断主小区(Primary Cell,PCell)切换条件是否满足从而只执行PCell切换过程,即PCell切换过程不伴随PSCell添加或改变;或者,终端在配置了CPAC时只判断是否PSCell添加或改变的执行条件是否满足,从而只执行PSCell添加或改变过程,即PSCell添加或改变过程不伴随PCell切换过程。
当前技术正在考虑引入的多个候选PSCell的条件PCell切换场景,但是在实际的评估过程中,候选PCell以及其对应的候选PSCell的执行条件很难同时得到满足,这就导致终端无法选择到合适的PCell以及对应的PSCell接入,从而导致切换失败。
