Description

一种被用于无线通信的节点中的方法和装置 技术领域
本申请涉及无线通信***中的传输方法和装置，尤其涉及无线通信中的用于小区切换的无线信号的传输方案和装置。
背景技术
在LTE***中，小区间切换(Handover)是基站基于UE的(User Equipment，用户设备)测量来控制的。3GPP(3rd Generation Partner Project，第三代合作伙伴项目)R(Release，版本)15中的小区间切换基本沿用了LTE中的机制。在NR(New Radio，新无线电)***中，更多应用场景需要被支持，一些应用场景，比如URLLC(Ultra-Reliable and Low Latency Communications，超高可靠性和低延迟通信)，对时延提出了很高的要求，同时也对小区间切换提出了新的挑战。
在NR***中，大尺度(Massive)MIMO(Multiple Input Multiple Output，多输入多输出)是一个重要的技术特征。大尺度MIMO中，多个天线通过波束赋型，形成较窄的波束指向一个特定方向来提高通信质量。多天线波束赋型形成的波束一般比较窄，通信双方的波束需要对准才能进行有效的通信。
发明内容
发明人通过研究发现，基于波束的通信会给小区间切换带来负面的影响，比如额外的延时和乒乓效应。如何降低这些负面影响，且提高终端切换的速度，并且进一步提高小区边界用户的性能来满足各类应用场景的需求，是需要解决的问题。
针对上述问题，本申请公开了一种解决方案。需要说明的是，虽然上述描述采用大尺度MIMO和基于波束的通信场景作为例子，本申请也适用于其他场景比如LTE多天线***，并取得类似在大尺度MIMO和基于波束的通信场景中的技术效果。此外，不同场景(包括但不限于大尺度MIMO，基于波束的通信和LTE多天线***)采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下，本申请的任一节点中的实施例和实施例中的特征可以应用到其他任一节点中，反之亦然。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
针对上述问题，本申请公开了一种层1/2的小区间切换和移动性管理的方法和装置。需要说明的是，在不冲突的情况下，本申请的用户设备中的实施例和实施例中的特征可以应用到基站中，反之亦然。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。进一步的，虽然本申请的初衷是针对蜂窝网，但本申请也能被用于物联网以及车联网。进一步的，虽然本申请的初衷是针对多载波通信，但本申请也能被用于单载波通信。进一步的，虽然本申请的初衷是针对多天线通信，但本申请也能被用于单天线通信。进一步的，虽然本申请的初衷是针对终端与基站场景，但本申请也同样适用于终端与终端，终端与中继，以及中继与基站之间的通信场景，取得类似的终端与基站场景中的技术效果。此外，不同场景(包括但不限于终端与基站的通信场景)采用统一的解决方案还有助于降低硬件复杂度和成本。
进一步的，在不冲突的情况下，本申请的第一节点设备中的实施例和实施例中的特征可以应用到第二节点设备中，反之亦然。特别的，对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS(Technical Specification)36系列、TS38系列、TS37系列中的定义。
