Description

一种被用于无线通信的方法和设备 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和小区切换相关的传输方法和装置。
背景技术
面对越来越高的通信需求，3GPP(3rd GenerationPartner Project，第三代合作伙伴项目)开始研究非地面通信(Non-Terrestrial Network，NTN)，3GPPRAN#80次会议决定开展“NR支持非地面网络的解决方案”研究项目，它是对前期“NR支持非地面网络”研究项目的延续(RP-171450)，其中切换(Handover)是一个重要的研究目标。
传统的宏蜂窝切换中，UE(UserEquipment，用户设备)对目标小区的信息进行测量，并选择RSRP(Reference Signal Received Power，参考信号接收质量)或者RSRQ(Reference SignalReceived Quality，参考信号接收质量)最好的小区进行接入。为解决热点地区的流量井喷和覆盖盲区问题，LTE(LongTermEvolution，长期演进)引入了异构网(Heterogeous Network)，在宏蜂窝中增加微小区(Picocell)的部署，为使微小区接纳更多的用户设备以获取更高的小区分裂增益，3GPP为小区切换引入了偏移量(Offset)，当微小区的RSRP加上偏移量大于宏小区(Macrocell)的RSRP时，UE将优先接入微小区。使用这种方法，在宏小区中部署较多微小区时，可以获得较大的小区分裂增益，提升网络频谱效率。
发明内容
当前的3GPP标准主要针对地面网络(Terrestrial Network，TN)，在切换相关的测量报告中，定义的偏移量类型主要包括小区专用偏移量(cell specific offsets)和频率专用偏移量(frequency specific offse)，与偏移量相关的RRC(RadioResurceControl，无线资源控制)IE(Information Element，信息元素)包括OffsetFreq、cellIndividualOffset、csi-RS-IndividualOffset、a3-Offset、a6-Offset、c2-Offset、h1-ThresholdOffset、h2-ThresholdOffset等。由于NTN环境中，卫星与用户设备(User Equipment，UE)之间的传输距离远远大于地面基站与用户设备之间的距离，从而会导致卫星与用户设备之间的传输时延远远大于地面通信，小区专用偏移量和频率专用偏移量难以保证用户设备在NTN环境中切换时的服务质量。
针对上述问题，本申请提供了一种解决方案。针对上述问题描述中，采用NTN场景作为一个例子；本申请也同样适用于例如地面传输的场景，取得类似NTN场景中的技术效果。此外，不同场景采用统一解决方案还有助于降低硬件复杂度和成本。
