Description

一种被用于无线通信的方法和装置 技术领域
本申请涉及无线通信系统中的方法和装置，尤其涉及无线通信中支持L1/L2(Layer 1/Layer 2，层1/层2)移动性增强时的调度的方法和装置。
背景技术
当UE(User Equipment，用户设备)从一个小区的覆盖范围移动到另一个小区的覆盖范围时，需要改变UE的服务小区。现有服务小区改变通常由L3(Layer 3，层3)测量触发，通过RRC(Radio Resource Control，无线资源控制)信令触发的包括同步的重配置(Reconfiguration with Synchronization)来实现。在L3实现的服务小区改变具有延时长，信令开销大和中断时间长的特性。为克服上述缺点，3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)在Rel(版本)-17中引入了双连接(Dual Connectivity，DC)，条件PSCell改变(Conditional PSCell(Primary SCG(Secondary Cell Group)Cell)change，CPC)，条件PSCell增加(CPA)，条件切换(Conditional Handover，CHO)等技术，但这些技术仍然都基于L3实现，无法完全解决上述问题。在3GPP RAN#94e次全会上决定对基于L1/L2的移动性增强技术启动WI(Work Item，工作项目)标准化工作，基于L1/L2的移动性增强技术的设计目标是实现UE的服务小区的快速改变。
传统通信中有两种传输方法，一种是动态调度(dynamic scheduling)的传输，即每次传输都是基于网络实时分配的空口资源；一种不是动态调度(without dynamic scheduling)的传输，即网络提前配置好空口资源，UE在配置好的空口资源上传输。不是动态调度包括半持续调度(Semi-Persistent Scheduling，SPS)和配置授予(Configured Grant，CG)，不是动态调度的传输适用于周期性业务。
发明内容
发明人通过研究发现，针对快速改变UE的服务小区的场景，当UE离开一个小区时，如果将半持续调度和/或配置授予类型2(type 2)清除，当UE很快又返回该小区，需要进行重新配置激活，会引入额外的信令开销，同时增加业务中断的时间。
针对上述问题，本申请公开了一种针对快速改变UE的服务小区场景中针对不是动态调度的传输，特别是半持续调度和配置授予类型2，进行维护的解决方案。在不冲突的情况下，本申请的第一节点中的实施例和实施例中的特征可以应用到第二节点中，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。进一步的，虽然本申请的初衷是针对Uu空口，但本申请也能被用于PC5口。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V2X(Vehicle-to-Everything，车联网)场景，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V2X场景和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。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TS36系列、TS38系列、TS37系列中的定义。
