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系统中的传输方法和装置，尤其涉及无线通信中的测量的方案和装置。
背景技术
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同的性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口技术(NR，New Radio)(或Fifth Generation，5G)进行研究,在3GPP RAN#75次全会上通过了NR的WI(Work Item，工作项目)，开始对NR进行标准化工作。
针对迅猛发展的车联网(Vehicle-to-Everything，V2X)业务，3GPP也开始启动了在NR框架下的标准制定和研究工作。目前3GPP已经完成了面向5G V2X业务的需求制定工作，并写入标准TS22.886中。3GPP为5G V2X业务识别和定义了4大用例组(Use Case Group)，包括：自动排队驾驶(Vehicles Platnooning)，支持扩展传感(Extended Sensors)，半/全自动驾驶(Advanced Driving)和远程驾驶(Remote Driving)。在3GPP RAN#80次全会上通过了NR V2X的技术研究工作项目(SI，Study Item)。
发明内容
5G NR和现有的LTE系统相比，一个显著的特征在于可以支持更加灵活的数理结构(Numerology)，包括子载波间隔(SCS，Subcarrier Spacing)，循环前缀(CP，Cyclic Prefix)长度，以及支持更加灵活的帧结构，包括对微时隙(Mini-slot)，小时隙(Sub-slot)和多个时隙聚合(Slot Aggregation)。这种灵活的数理结构和灵活的帧结构可以更好地满足多种新的业务需求，尤其是垂直行业的非常多样性的业务需求。更加严格的负载均衡控制是车联网和传统的蜂窝网络相比的一个重要的特点，有效的负载控制可以降低业务冲突的概率，提高传输可靠性，这些对于车联网业务尤为关键。在LTE V2X系统中，设计的负载控制的测量机制是基于单一的数理结构(15kHz SCS，正常CP长度，1毫秒子帧长度)的，这无法满足5G NR V2X中对于更加灵活的数理结构的需求。
针对NR V2X中的测量的问题，本申请公开了一种解决方案。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。
