具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统，全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统，未来的第五代(5th Generation，5G)系统，如新一代无线接入技术(new radio access technology，NR)，及未来的通信系统，如6G系统等。
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
另外，在本申请实施例中，“示例的”一词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
本申请实施例中，信息(information)，信号(signal)，消息(message)，信道(channel)有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或传输接收点(Transmission and Reception Point,TRP)，并与一个集中控制器(controller)相连。当UE在Hyper cell内移动时，网络侧设备时时为UE选择新的sub-cluster(子簇)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。或者是，在以UE为中心的网络中，多个网络侧设备，如小站，可以有独立的控制器，如分布式控制器，各小站能够独立调度用户，小站之间在长期上存在交互信息，使得在为UE提供协作服务时，也能够有一定的灵活性。
为便于理解本申请实施例，首先以图1中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1示出了适用于本申请实施例的通信方法的通信系统的示意图。如图1所示，该通信系统100包括网络设备102和终端设备106，网络设备102可配置有多个天线，终端设备也可配置有多个天线。可选地，该通信系统还可包括网络设备104，网络设备104也可配置有多个天线。
应理解，网络设备102或网络设备104还可包括与信号发送和接收相关的多个部件(例如，处理器、调制器、复用器、解调器或解复用器等)。
其中，网络设备为具有无线收发功能的设备或可设置于该设备的芯片，该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭 基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(DU，distributed unit)等。
终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。本申请中将具有无线收发功能的终端设备及可设置于前述终端设备的芯片统称为终端设备。
在该通信系统100中，网络设备102和网络设备104均可以与多个终端设备(例如图中示出的终端设备106)通信。网络设备102和网络设备104可以与类似于终端设备106的一个或多个终端设备通信。但应理解，与网络设备102通信的终端设备和与网络设备104通信的终端设备可以是相同的，也可以是不同的。图1中示出的终端设备106可同时与网络设备102和网络设备104通信，但这仅示出了一种可能的场景，在某些场景中，终端设备可能仅与网络设备102或网络设备104通信，本申请对此不做限定。
应理解，图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备或者还可以包括其他终端设备，图1中未予以画出。
下面结合附图详细说明本申请实施例。
应理解，本申请的技术方案可以应用于无线通信系统中，例如，图1中所示的通信系统100，该通信系统可以包括至少一个网络设备和至少一个终端设备，网络设备和终端设备可以通过无线空口通信。例如，该通信系统中的网络设备可以对应于图1中所示的网络设备102和网络设备106，终端设备可以对应于图1中所示的终端设备104。

图2为本申请实施例的一种通信方法的流程示意图，如图2所示，该方法可以包括以下步骤：
步骤201：网络侧设备向终端发送广播多播服务的标识与用于所述广播多播服务的传输带宽的对应关系。
本实施例为网络侧对应的通信方法，这里的广播多播服务的传输带宽可以为传输MBMS数据的一个特定的子频段，为便于理解，后文中部分地方采用MBMS subband(MBMS子带)指代广播多播服务的传输带宽。以下给出本申请中MBMS subband的一种详细解释：多个连续的公共资源块(common resource block，CRB)组成的集合。该集合由MBMS subband起始位置和MBMS subband带宽确定。其中MBMS Subband起始位置即为相对point A(5G中定义的一个频域上的参考点)的距离，用CRB个数表示。MBMS subband的大小用资源块(resource block，RB)的个数表示。
本申请中网络侧设备向终端发送对应关系，其目的可以是指示终端MBMS服务所使用的MBMS Subband，进而终端可以根据该信息在确定的MBMS Subband上进行广播多播服务的数据传输。这里的对应关系可以是以任一形式来表示，例如可以用列表的形式来表示。
在一个实施例中，所述广播多播服务的标识至少包括TMGI(Temporary Mobile Group Identity，临时移动组标识)，或，所述广播多播服务的标识至少包括TMGI和SESSION ID(Session Identity，会话身份标识)。这里TMGI可以用于唯一的标识广播多播服务，SESSION ID可以用于唯一的标识创建的会话。
在一个实施例中，所述广播多播服务的传输带宽包括部分带宽。
需要说明的是，部分带宽(Bandwidth part，BWP)为5G中引入的概念，5G NR技术中引入了带宽自适应技术(BA)，带宽自适应技术通过将整个频段划分成多个子调度带宽分段(BWP)，根据需要为终端分配不同的BWP，BWP可以高效利用5G NR的大带宽频率资源。对于不同终端，对于同一终端的不同业务需要，网络侧可以根据需要灵活的为其分配不同的频率资源。终端无需始终监听整个频段。例如，可以是初始部分带宽initial BWP(用于传输系统信息和寻呼的传输子带宽)，也可以是初始部分带宽以外的部分带宽，即initial BWP其他的BWP。以上述情况为例，网络侧设备如5G基站可以向终端设备例如手机发送initial BWP与TMGI/SESSION ID的对应关系。本实施例是基于5G应用场景下，针对5G的数据传输带宽BWP进行举例，实际应用场景可以不限于5G场景下，这里部分带宽也可以是新定义的部分带宽。
在一个实施例中，所述对应关系可以承载于系统消息或所述多播广播服务的控制消息中。
步骤202：所述网络侧设备在所述对应关系所包括的传输带宽上发送广播多播服务的数据。
例如，网络侧设备向终端通知了initial BWP与TMGI/SESSION ID的对应关系，则网络侧设备在initial BWP上发送MBMS数据。
在一个实施例中，所述方法还包括：所述网络侧设备发送寻呼消息或系统信息对应的调度信息，所述调度信息用于指示所述终端由所述传输带宽切换至初始部分带宽上接收所述寻呼信息或系统信息；其中，所述调度信息承载于所述广播多播服务的传输带宽对应的PDCCH(Physical Downlink Control Channel，下行物理控制信道)上。例如，当终端在MBMS subband上传输 MBMS数据时，网络侧向终端发送系统消息的调度信息，指示终端由当前的MBMS subband切换到initial BWP上面接收该系统消息。
在一个实施例中，所述方法还包括：获取终端发送的广播多播服务的标识以及所述终端的部分带宽的能力信息；基于所述部分带宽的能力信息，确定为所述终端配置的第一部分带宽，所述标识对应的广播多播服务的传输带宽位于所述第一部分带宽的频域范围之内；向所述终端发送配置信息，所述配置信息用于指示所述第一部分带宽。这里，MBMS数据需要在MBMS subband上进行传输。而对于目前5G场景下，终端通过BWP来进行数据的接收。因此，可以根据终端的部分带宽能力为终端配置一个部分带宽(第一部分带宽)，以使得该部分带宽在频域上覆盖MBMS subband，从而可以使得终端能够获取到网络侧设备的MBMS数据。
本实施例中，部分带宽的能力信息可以是BWP能力限制指示，用于指示终端可同时支持多少个BWP。例如现有5G标准下终端可同时使用一个BWP，那么针对现有的终端该部分带宽的能力信息指示终端支持1个BWP。若终端可同时使用3个BWP，那么针对该终端，部分带宽的能力信息指示终端支持3个BWP或者可以指示终端支持多个BWP(不明确指示支持的BWP的数量)。
在一个实施例中，在所述基于所述部分带宽的能力信息，确定为所述终端配置的第一部分带宽之前，所述方法还包括：确定所述终端的广播多播服务的优先级大于预设优先级阈值。这里网络侧设备可以根据MBMS的标识例如TMGI确定对应的服务种类，判断该服务的优先级。若优先级高，则可以继续为终端配置第一部分带宽。例如，针对公共安全类的MBMS服务，判断优先级大于设置的优先级阈值，则继续为终端配置第一部分带宽。
在一个实施例中，所述基于所述部分带宽的能力信息，确定为所述终端配置的第一部分带宽，包括：获取所述终端的单播服务当前占用的第二部分带宽；若所述传输带宽位于所述第二部分带宽的频域范围内，确定所述第二部分带宽为所述第一部分带宽；若所述传输带宽的全部或部分频域范围位于所述第二部分带宽的频域范围外，从所述终端支持的部分带宽中确定第三部 分带宽为所述第一部分带宽，所述第三部分带宽与所述第二部分带宽不同。
本实施例中，通过判断当前终端进行单播服务占用的部分带宽的频域范围是否在MBMS subband之内(包括重叠的情况)。若是，则网络侧设备可以不用为终端重新配置新的BWP，只需要对该单播服务占用的部分带宽进行保持；若否，则网络侧设备可以为终端重新配置新的BWP，从终端支持的其他BWP中确定出第三部分带宽(频域范围覆盖了MBMS subband)，并将第三部分带宽的配置信息下发至终端。
在一个实施例中，所述获取终端的广播多播服务的标识以及所述终端的部分带宽的能力信息，包括：接收所述终端发送的第一消息，所述第一消息包括所述终端的广播多播服务的标识以及所述部分带宽的能力信息；或者，接收所述终端的源小区的网络设备发送的第二消息，所述第二消息包括所述终端的广播多播服务的标识以及所述部分带宽的能力信息。
本实施例对应的应用场景可以是，当终端与网络侧设备建立RRC连接时，接收终端向网络侧设备发送的RRC连接建立请求消息(第一消息)或接收终端在与网络侧设备建立了RRC连接后发送的RRC消息(第一消息)；另外，也可以是当终端发生小区切换时，由终端所在的源小区的网络设备发送的第二消息。
可选的，第一消息承载于无线链路控制RRC信令中。
可选的，所述第二消息承载于多个网络侧设备之间的接口消息中，例如Xn接口消息中。
在一个实施例中，所述方法包括：向所述终端发送第一切换指示信息，所述第一切换指示信息用于指示所述终端切换至所述传输带宽上进行所述广播多播服务的数据传输；其中，所述第一切换指示信息承载在所述终端当前单播服务占用的部分带宽对应的物理下行控制信道PDCCH上。
本实施例中，终端传输单播服务的数据所占用的传输带宽与传输MBMS数据占用的传输带宽不同，网络侧在当前单播服务占用的BWP对应的PDCCH上发送第一切换指示信息。例如发送对应PDCCH上的下行控制信息(downlink  control information，DCI)。终端在接收到该DCI后，可以由从单播服务的传输带宽切换至MBMS的传输带宽上接收MBMS数据。具体地，可以在PDCCH上传输的DCI信息中，增加一个比特用于MBMS subband/BWP切换指示。
在一个实施例中，所述方法还包括：向所述终端发送第二切换指示信息，所述第二切换指示信息用于指示所述终端切换至第一部分带宽进行单播服务的数据传输，所述第二切换指示信息承载在所述终端当前广播多播服务占用的传输带宽对应的物理下行控制信道PDCCH上。
本实施例中，终端传输单播服务的数据所占用的传输带宽与传输MBMS数据占用的传输带宽不同，网络侧在当前MBMS占用的传输带宽对应的PDCCH上发送第二切换指示信息。例如对应PDCCH上的下行控制信息(downlink control information，DCI)，终端在接收到该DCI后，可以由从MBMS的传输带宽切换至单播服务的传输带宽上接收单播服务的数据。
需要说明的是，第一切换指示信息和第二切换指示信息可以由网络侧根据终端具体使用的MBMS选择通过时分复用的方式，在不同时刻下发至终端，用于分别将终端调度到MBMS subband以及单播业务的BWP上，并且可以用于指示终端进行MBMS服务和单播业务的切换。
在一个实施例中，所述方法还包括：当接收到终端发送的退出广播多播服务的指示信息后，禁止使用第一模式为所述终端配置部分带宽。所述第一模式为根据所述终端选择的广播多播服务的标识对应的传输带宽为所述终端配置部分带宽的模式。
本实施例中，终端单方面结束MBMS的数据接收后，终端可以通知网络侧设备，当网络侧设备接收到终端发送的退出广播多播服务的指示信息后，不再限制根据终端选择的广播多播服务的标识对应的传输带宽为终端配置BWP，网络侧设备可以恢复正常的BWP配置流程。
