For example, the UE can only support a small bandwidth (such as 20MHz) without supporting the entire bandwidth (such as 100MHz); it can use a larger bandwidth when there is a large number of service transmissions. When there is no service or only a small amount of service is transmitted, a smaller bandwidth is used, thereby reducing the power consumption of the UE.

Description
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多播和广播有关的传输方案和装置。
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。
NR的其中一个关键技术是支持BWP(Bandwidth Part,带宽部分)。BWP是小区整个带宽的子集;每个BWP的大小,以及使用的SCS(Subcarrier Spacing,子载波间隔)和CP(Cyclic Prefix,循环前缀)类型都可以灵活配置。BWP的作用如下:可以降低UE的能力要求,例如UE可以只支持小的带宽(如20MHz)而不用支持整个带宽(如100MHz);可以在有大量的业务传输是使用较大的带宽,而在没有业务或只有少量业务传输时使用较小的带宽,从而降低UE的电量消耗。UE可以被配置一个或多个BWP,多个配置的BWP之间通过RRC信令、DCI、inactivity timer或伴随着随机接入的发起等方式执行BWP切换(switching/switch)。
广播(Broadcast)/多播(Multicast)传输技术被广泛用在蜂窝网系统中,例如4G LTE(Long Term Evolution,长期演进)系统中的MBMS(Multimedia Broadcast Multicast Service,多媒体广播多播服务)。广播/多播传输的主要特征是,网络设备可以同时向多个终端节点发送同样的广播/多播数据,它在广播电视、灾害预警、紧急业务、工业控制、车联网等场景具有重要的价值。在LTE MBMS中,eNB通过一个PDCCH(Physical Downlink Control Channel,物理下行控制信道)来调度多个终端节点接收包含了广播/多播数据的PDSCH(Physical Downlink Shared Channel,物理下行共享信道)或PMCH(Physical Multicast Channel,物理多播信道)。广播/多播相关的标识包括SC-RNTI(Single Cell RNTI,单小区RNTI),SC-N-RNTI(Single Cell Notification RNTI,单小区通知RNTI)和G-RNTI(Group RNTI,分组RNTI)。
在3GPP RAN#86次全会上通过了NR Multicast的WI(Work Item,工作项目),开始对NR通过SC-PTM(Single Cell Point-to-MultiPoint,单小区点到多点)方式提供多播和广播业务进行标准化工作。
发明内容
发明人通过研究发现,广播/多播信号可能在单播信号的BWP上传输,当前的BWP管理只考虑单播信号传输的影响,如何进行广播/多播信号传输时的BWP管理和计时器管理是一个需要解决的问题。
针对上述问题,本申请公开了一种解决方案。需要说明的是,虽然上述描述采用网络设备和终端设备之间的通信的场景作为一个例子,本申请也适用于其他通信场景(例如终端到终端之间的通信的场景),并取得类似的技术效果。此外,不同场景(包括但不限于网络设备和终端之间通信和终端到终端之间通信的场景)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。
