数据传输方法、装置、设备和存储介质 技术领域

蜂窝网络架构通过频率复用和小区分裂技术，提高频谱资源的利用率和系统容量，支撑移动通信快速发展。为了满足持续增加的流量需求，从第一代移动通信技术(the 1st Generation mobile communication technology，1G)到5G整个移动通信的演进都是以蜂窝网为基础，即采用宏蜂窝小区分裂和纵向微蜂窝网络分层的方式。
随着各种微小区、小小区、家庭基站以及中继节点在内的各种低功率节点(Low Power Node，LPN)在传统蜂窝网络的部署，蜂窝网络呈现越来越密集化的趋势，由于每个小小区(微小区)都是一个独立的小区，用户终端(User Equipment，UE)每进入一个小小区，就要重新进行下行同步，获取该小小区的系统消息，UE在空闲态移动过程中会频繁进行小区切换，浪费大量UE功耗，如果网络要寻呼UE，需要在很多小小区进行寻呼，而UE仅位于一个小小区内，这导致大量的下行资源浪费；网络侧基于固定的小区部署发送同步和寻呼空闲UE，这也限制了下行数据传输的灵活性，导致传输效率下降，也增加了网络侧的功耗。

UE接入网络后(或进入连接态后)，基站通过UE专有RRC信令还配置专用于UE检测寻呼PDCCH的同步信号(也可以用于上行接入时下行同步)；所述接入资源在所述寻呼资源之后，UE利用寻呼同步信号进行下行同步，发送上行接入信号；也可以不配置专用于UE检测寻呼PDCCH的同步信号，利用空闲态下行同步信号实现同步以及辅助寻呼检测。
在UE进入空闲态后在上述指定的寻呼搜索空间上检测寻呼RNTI加扰的寻呼PDCCH；如果收到寻呼消息或有上行数据传输时，检测同步信号块(Synchronization Signal Block，SSB)和SI，如果检测到SSB和SI则按照常规流程接入，如果没有检测到SSB和SI，在上述配置的接入资源位置上发起接入信号，在配置的接入响应搜索空间上检测接入响应，接入网络；UE在空闲态检测寻呼PDCCH前，可以使用上述专有同步信号进行下行同步。
当UE检测到的寻呼下行同步信号与所配置的同步信号不同时，发起接入，更新寻呼配置(寻呼区域更新)；或者，当UE检测到的空闲态下行同步信号与所配置的同步信号不同时，发起接入，更新寻呼配置；或者，当UE检测到的空闲态下行同步信号的强度小于阈值时，发起接入，更新寻呼配置；或者，当UE检测到的寻呼下行同步信号的强度小于阈值时，发起接入，更新寻呼配置。
