如图2所示，为本申请一示例性实施例提供的多播业务的传输方法200的流程示意图，该方法可以但不限于由终端执行，具体可由安装于终端中的硬件和/或软件执行。本实施例中，所述方法200至少可以包括如下步骤。
S210，终端在感兴趣多播业务或进行多播业务接收的情况下，向与单播业务对应的网络侧设备发送所述多播业务的相关信息。
其中，所述终端可以处于连接态、且能进行单接收模式(Receive Only Mode，ROM)，或者，所述终端处于连接态、且所述终端进行单播业务的网络侧设备(也可称作服务基站或单播服务基站)与所述终端进行多播业务的网络侧设备(也可称作服务基站或多播服务基站)不同，或者，所述终端处于连接态、且所述终端进行单播业务的公共陆地移动网络(Public Land Mobile Network，PLMN)与所述终端进行多播业务的PLMN不同，那么，单播业务对应的网络侧设备可能不清楚或无法获取多播业务(如终端所感兴趣的多播业务或正在进行接收的多播业务等)的相关信息，那么，必然会使得所述单播业务对应的网络侧设备无法实现对单播业务的精准调度，基于此，本申请在所述终端感兴趣多播业务或进行多播业务接收的情况下，及时向与单播业 务对应的网络侧设备发送所述多播业务的相关信息，如所述终端的能力信息(也可理解为所述终端更新后的能力信息)、所述多播业务的载波特征信息、所述多播业务的时域周期信息中的至少一项，使得所述网络侧设备可以根据所述终端的能力信息、所述多播业务的载波特征信息(如频点信息、带宽信息、载波配置信息等)、所述多播业务的时域周期信息等进行单播业务的调度，既保障了终端接收多播业务的接收性能，还确保了单播业务的传输和系统效率。
也就是说，所述终端通过所述能力信息和所述载波特征信息的上报，能够使得所述单播业务对应的单播服务基站能够对所述终端的能力进行更好的评估，进而更有针对性的进行单播调度。
此外，由于所述多播业务的时域周期信息用于指示所述能力信息和/或所述多播业务的载波特征信息的生效时域，那么，所述网络侧设备可以利用所述时域周期信息，进行更精准的能力和/或载波分配，使得终端在不接收多播业务的间隙，能够提升单播业务调度能力，避免系统资源浪费。
当然，在本实施例中，所述终端可以通过以下(11)-(13)任一项进行所述多播业务的相关信息的传输。
(11)多播业务感兴趣指示(MBS Interest Indication)。
(12)终端辅助信息(UE assistance information)。
可以理解，对于前述(11)-(12)可以理解为：所述终端可以复用所述多播业务感兴趣指示或所述终端辅助信息进行所述多播业务的相关信息的传输。
(13)第一信令，所述第一信令由协议约定、且专用于所述多播业务的相关信息的上报。其中，所述第一信令可以是能力更新信令(Capability update)等，在此不做限制。
一种实现方式中，对于所述多播业务的相关信息的上报时机(也可以理解为触发时机)，所述终端在开始所述多播业务时上报、也可以是在结束所述 多播业务时上报、还可以是在接收所述多播业务的载波特征、能力信息等发生变化/变更时上报等，在此不做限制。
本实施例中，所述终端通过在感兴趣多播业务或进行多播业务接收的情况下，向与单播业务对应的网络侧设备发送所述多播业务的相关信息，如能力信息、所述多播业务的载波特征信息、所述多播业务的时域周期信息中的至少一项，由此，使得所述网络侧设备可根据能力信息、所述多播业务的载波特征信息、所述多播业务的时域周期信息中的至少一项对所述终端的能力进行精准的评估，进而实现对所述单播业务的精准调度。同时，还能够在所述终端不进行多播业务的间隙，大幅提升了单播业务的调度能力，改善了用户体验，避免了系统资源浪费。
如图3所示，为本申请一示例性实施例提供的多播业务的传输方法300的流程示意图，该方法可以但不限于由终端执行，具体可由安装于终端中的硬件和/或软件执行。本实施例中，所述方法300至少可以包括如下步骤。
S310，终端在感兴趣多播业务或进行多播业务接收的情况下，向与单播业务对应的网络侧设备发送所述多播业务的相关信息。
其中，所述多播业务的相关信息至少包括所述终端的能力信息、所述多播业务的载波特征信息、所述多播业务的时域周期信息中的至少一项，所述多播业务的时域周期信息用于指示所述能力信息和/或所述多播业务的载波特征信息的生效时域(或生效时域信息)。
可以理解，S310的实现过程除了可参照方法实施例200中的相关描述之外，作为一种可能的实现方式，所述载波特征信息可以包括多播业务接收的频点信息、带宽信息、多播业务的载波配置情况(如数值(numerology)、子载波间隔(Subcarrier Spacing，SCS))等。其中，多播业务的接收的频点和带宽应该至少在终端的CA波段组合(carrier band combination)的范围之内，即在终端的基本接收带宽组合之内，而多播载波的numerology情况，决定了终端的处理能力，例如不同的子载波间隔需要的处理复杂度(例如离散傅里 叶变换(Discrete Fourier Transformation，DFT))不一样，例如：15kHz numerology 2k DFT、7.5kHz numerology:4k DFT、1.25kHz numerology:24k DFT。
也就是说，如果终端下行最大支持5DL CC with 15kHz子载波间隔，那么当它接收了一个多播业务的7.5kHz或者1.25kHz子载波间隔时，相当于不能再支持其它4个DL CC，即终端的能力限制了，因此不仅需要上报载波还需要增加特殊numerology上报，告知单播服务基站关于一个DL CC以及对应numerology更高处理能力的消耗和占用。特别的，当多播接收的numerology缺省时，可以认为对应于默认的参数，例如15kHz子载波间隔。
进一步，所述能力信息可以是多播业务载波占用的能力信息。即所述终端可以直接上报缩减之后的能力信息，因为终端已经在特定的频点和带宽上进行了多播业务的接收，因此，终端此时可以认为CA band combination已经发生了变化，即终端不再支持原有CA band combination里不包括多播载波频点/带宽的组合，只能支持包含其他的组合，因此CA band combination需要更新，相应的，终端需要将更新后的CA band combination上报给所述网络侧设备。对于该上报方式，可以理解为终端在维持基本能力信息不变的基础上上报备多播业务载波占用的部分，从而使得网络侧设备具有更多的控制余量。
或者，所述能力信息也可以包括终端除被所述多播业务载波占用的能力之外的剩余能力信息。即所述终端自行计算排除所述多播业务之外的其余剩余能力信息，将更新之后的能力再次上报给网络侧，使得终端可以自行进行能力分配，进而可以兼容更多的其它情况，例如多卡终端在不同运营商网络中的能力动态分配问题等。例如，从numerology角度来说，由于多播业务载波的子载波间隔可能是通常的15kHz，也可能是其它的非常用间隔，因此终端以根据已经占用的处理能力，计算剩下的处理能力，并将剩下的处理能力上报给网络侧，作为能力信息。
需要注意的是，一旦终端进行了前述的载波特征信息或者能力信息的上 报，则意味着单播服务基站需要一直使用缩减或者变更的能力信息进行单播业务调度的限制。但是考虑到在实际的多播业务的传输中，大多数的多播业务都是具有一定的周期特征，即多播业务只在一定的时域周期位置进行传输，其它位置不用进行多播接收。对此，本申请中考虑将这些时域周期信息也同时上报给单播服务基站，使其可以仅在多播业务传输的期间(或激活时间(active time))进行能力或者单播调度限制操作，而在不需要多播业务接收的非激活时间(inactive time)期间，可以使用全能力进行单播业务调度，从而最大限度的使用终端能力，为终端的多播业务和单播业务提供了更好的接收效果以及确保了系统资源效率。
基于此，作为一种实现方式，所述终端上报给所述单播服务基站的所述时域周期信息至少可以包括以下(21)-(26)中的至少一项。
(21)所述多播业务的非连续接收(Discontinuous Reception，DRX)配置。
(22)所述多播业务的周期长度。
(23)所述多播业务的周期的起始位置。
其中，所述起始位置可以是绝对位置或相对位置等，在此不做限制。
(24)所述多播业务的持续时间(onDuration，或者称作持续时间定时器)的长度。
本实施例中，如果将前述(21)-(24)组合、且所述多播业务可以以40ms为周期(即周期长度)，那么，多播业务的接收可在0-40ms、40ms-80ms等周期进行重复，on Duration定时器的长度为5ms，即所述终端在每个周期的前5ms需要进行所述多播业务的接收，后35ms不需要进多播业务的接收。
(25)所述多播业务的激活时间(active time)的周期信息。
(26)所述多播业务的active time在每个周期中的图案(pattern)信息(即active time pattern)。
本实施例中，如果将前述(25)-(26)组合，那么，单播服务基站可以 采取更灵活的active time pattern配置，例如所述多播业务以10ms为周期，在5ms-15ms、15ms-25ms等周期进行重复，每个周期内部的active time可以采取位图(bitmap)或者其它方式进行配置或者指示，例如“0011100110”规定一个周期内部具体的active/inactive的pattern，其中“1”代表该时域位置为active/on(即接收多播业务)，“0”代表该时域位置为inactive/off(即不接收多播业务)，每个比特(bit)代表1ms。
对此，如果所述终端在进行不止一个多播业务接收时，或者所述终端感兴趣的不止一个所述多播业务时，所述终端上报的所述多播业务的载波特征信息/能力变更信息与周期时域信息之间可以存在对应关系(或映射关系)，以实现灵活的信息上报。
例如，在一种实现方式中，在所述多播业务的相关信息包括多个所述多播业务的载波特征信息的情况下，所述多播业务的载波特征信息与所述周期时域信息之间可以满足第一映射关系。其中，所述第一映射关系包括以下(31)-(33)中的任一项。
(31)所述载波特征信息与所述周期时域信息一一对应。
例如，假设所述周期时域信息为激活时间配置(active time configuration)，那么，载波特征信息1对应active time configuration 1、载波特征信息2对应active time configuration 2，……，依次类推。其中，所述终端在每个载波上接收一个或多个多播业务。
(32)多个所述载波特征信息对应于同一个所述周期时域信息。
例如，假设所述周期时域信息为active time configuration，那么，载波特征信息1和载波特征信息2等均对应active time configuration 1，如可以all-to-1对应。其中在每个载波上接收一个或者多个多播业务。
(33)在所述多个载波特征信息被划分为多个组下，属于同一组中的载波特征信息对应于相同的所述周期时域信息，或者，属于不同组中的载波特征信息对应于相同的所述周期时域信息，或者，属于不同组中的载波特征信 息对应不同的所述周期时域信息。
例如，假设所述周期时域信息为active time configuration、且所述多个载波特征信息来自于载波特征信息组1和载波特征信息组2，那么，属于同一载波特征信息组中的一个或多个不同的载波特征信息对应同一个周期时域信息，如active time configuration 1等；或者，载波接收信息组1、载波特征信息组2，……均对应同一个周期时域信息，如active time configuration 1等；或者，载波特征信息组1对应active time configuration 1，载波特征信息组2对应active time configuration 2，……，依次类推。其中，每个载波特征信息组包含一个或者多个载波特征信息，在每个载波上接收一个或者多个多播业务。
相似的，在另一种实现方式中，在所述多播业务的相关信息包括多个所述能力信息的情况下，所述能力信息与所述周期时域信息之间满足第二映射关系。其中，所述第二映射关系包括以下(41)-(43)中的任一项。
(41)所述能力信息与所述周期时域信息一一对应。
例如，假设所述周期时域信息为active time configuration，那么，能力信息1对应active time configuration 1、能力信息2对应active time configuration2，……，依次类推，可以一一对应。其中，每个能力信息是由于一个或者多个多播业务接收所引起的，这些多播业务可以位于同一个载波，也可位于不同载波。
(42)多个所述能力信息对应于同一个所述周期时域信息。
例如，假设所述周期时域信息为active time configuration，那么，能力信息1、能力信息2、……、均对应active time configuration 1，即all-to-1对应。其中，能力信息是由于所有多播业务接收所引起的。
(43)在多个所述能力信息被划分为多个组情况下，属于同一组中的能力信息对应于相同的所述周期时域信息，或者，属于不同组中的能力信息对应相同的所述周期时域信息，或者，属于不同组中的能力信息对应不同的所 述周期时域信息。
例如，假设所述周期时域信息为active time configuration、且所述多个能力信息来自于能力信息组1和能力信息组2，那么，属于同一能力信息组中的一个或多个不同的能力信息对应同一个周期时域信息，如active time configuration 1等；或者，能力信息组1、能力信息组2，……均对应同一个周期时域信息，如active time configuration 1等，或者，能力信息组1对应active time configuration 1，能力信息组2对应active time configuration 2，……，依次类推。其中，每个能力信息组包含一个或者多个能力信息。
当然，当网络侧设备接收到所述终端的载波特征信息或者能力信息以及对应的周期时域信息上报之后，会在对应的生效时域范围之内，考虑终端的剩余能力进行单播业务的调度，以避免对多播业务接收的影响，同时最大限度的确保单播业务和多播业务一起正常接收。
进一步，考虑到所述周期时域信息是通过上行(Uplink，UL)无线资源控制(Radio Resource Control，RRC)信令进行上报的，因此只能上报相对半静态的时域信息，例如DRX onDuration或者半静态的周期pattern。但是通常来说，所述多播业务除了周期业务，还会有一些非周期业务，或者周期业务中也会存在一些额外信息或者每个周期业务的业务量存在一定的波动，由此可能会造成多播业务的传输并不能完全限制在一定的静态时间之内，如存在延伸的active time。
例如，除了DRX onDuration的配置之外，依然需要非激活定时器(Inactivity timer)的配置，当网络侧设备配置了Inactivity timer为非零的数值，则意味着终端在接收到网络侧设备发送的关于多播业务的新调度信令时会启动或重启inactivity timer。在inactivity timer运行期间，终端的多播业务接收仍旧处于active time范围，即终端仍旧是需要进行多播业务的接收准备。也就是说终端在多播载波上的接收时间范围将会进行动态的调整，不再是满足以静态信令通知的周期时域信息。
对此情况，作为一种实现方式，所述终端可以向所述网络侧设备发送第一指示信息，以用于向所述网络侧指示所述active time的扩展信息，即动态时域信息，使得网络侧设备更好的调度单播业务。可选的，所述扩展信息至少可以包括相对时间、绝对时间、结束时间、开始时间中的至少一项。
其中，所述绝对时间是指所述终端动态的上报当前的active time被扩展到哪个时刻、哪个系统帧号(System frame number，SFN)、哪个时隙(slot)等。
所述相对时间是指active time以当前的上报时间点为上报时间参考点向后再扩展多少个毫秒或者slot等。可以理解，相对于所述绝对时间，所述相对时间的上报具有更小的开销，但是需要所述终端和网络侧设备对于上报时间参考点理解一致且完全同步。
所述active time的起始时间：由于active time的起始时间通常是比较清楚的，在onDuration的起始位置开始或者pattern里静态指示“on”的位置开始，因此起始时间的指示不是必须的，或者，所述起始时间的指示可用于部分情况，如当单播服务基站对active time的再次(重新)开始时间不清晰的时候可进行所述active time的起始时间的指示。
所述active time的结束时间：由于active time可能变成动态的扩展，因此active time在每个周期的结束位置是不固定的。例如，受多播业务到达的随机性影响，所述终端可以根据实际多播业务的到达情况，在每次多播业务的接收active time的结束位置，给单播服务基站发送一个active time结束(off)的指示。相应的，单播服务基站接收到该active time off之后，就知道本周期的多播业务接收结束，后面的单播调度可以不用在顾虑多播业务接收引起的能力缩减问题。
需要理解的是，所述active time的扩展信息对应至少一个多播业务。或者，当所述终端在多个载波上接收多播业务时，所述终端上报的载波特征信息或者能力信息可以是多个，那么动态active time的变更指示或者结束指示 (即第一指示信息)也可以根据所述多播业务、所述载波特征信息、能力信息的上报需要进行指示，如多次指示等。此外，在所述第一指示信息为active time的结束时间指示时，第一指示信息可以为每个不同的载波特征信息配置不同的资源，由此使得终端可在不同资源上指示的就是对应载波的active time结束位置或者共享资源，但所述终端需要在第一指示信息中区分载波特征信息。
此外，由于所述终端利用所述第一指示信息实现的是动态指示，因此在本申请中，所述第一指示信息可以采用时延较低的传输方式，例如，所述第一指示信息可以为L1信令(signaling)、媒体接入控制(Medium Access Control，MAC)信令等。以L1 signaling为例，网络侧设备可以为所述终端配置一些周期性的上行L1信令资源，用于快速传输上行active time扩展信息指示，即第一指示信息。
可以理解，当网络侧设备接收到所述终端上报的载波特征信息/能力变更信息、时域周期信息以及动态时域指示信息后，网络侧设备便可以动态的在对应的时域范围之内，评估终端的剩余能力以进行单播业务的调度，从而既能避免对多播业务接收的影响，还能最大限度的确保单播和多播一起正常接收。
进一步，对于前述的终端能力变更，由于终端在进行能力调整时也需要一定的时间，例如终端需要在时刻T1开始进行MBS业务接收，那终端可能需要在T1-t1时刻开始调整自己的接收机和/或处理器分配；又例如，终端在时刻T2结束多播业务接收，则终端可能在时刻T2+t1时刻才能完成全部的接收机调整和/或处理器调整，具备全能力处理单播业务接收的状态。也就是说，终端的能力分割的改变，可能需要一定的调整时长。而这个调整时长，受终端具体能力(如硬件能力等)的限制，即每个终端的能力调整时间可能不一样，如，有的终端可能微秒级别可以完成能力调整，有的终端需要毫秒级别才能完成能力调整，那么，对于具有不同调整能力的终端，网络侧设备在调 度时需要的缓冲或者生效时长就不一样，因此网络侧设备需要知道每个终端的调整能力的大小。对此，本申请提供如下两种方式，以使得网络侧设备获知每个终端的调整能力(即调整能力信息)，内容如下。
方式1：终端可通过多播业务的相关信息向所述网络侧设备上报所述终端的调整能力的大小(调整能力信息)，即所述多播业务的相关信息除了包括能力信息、所述多播业务的载波特征信息、所述多播业务的时域周期信息之外，还可还包括所述终端的业务调整能力信息。其中，所述业务调整能力信息用于指示所述终端从第一模式调整为第二模式所需的时间，和/或，所述终端从第二模式调整为第一模式所需的时间，所述第一模式为所述终端同时进行多播业务接收和单播业务接收，所述第二模式为所述终端进行单播业务接收、且不进行多播业务接收。
示例性，终端在上报能力信息、所述多播业务的载波特征信息、所述多播业务的时域周期信息时，可同时上报自己的调整能力信息。例如终端1上报自己在x1毫秒之内完成由兼顾多播业务接收和单播接收的第一模式快速调整为仅单播接收的第二模式，和/或，在y1毫秒之内完成由仅单播接收的第二模式调整为多播业务和单播共同接收的第一模式。其中，x1和y1可以相同，也可以不同。终端2也可以进行自己的上报，由此，网络侧设备便可根据不同终端的能力，对每个终端进行相应的调度。
方式2：协议约定或预配置一个最小能力要求，例如协议约定所有的终端都在x毫秒之内完成由兼顾多播业务接收和单播业务接收的第一模式快速调整为仅单播业务接收的第二模式，或者协议约定所有终端都在y毫秒之内完成由仅单播接收的第二模式调整为多播业务和单播业务共同接收的第一模式。其中，x和y可以相同，也可以不同，由此使得网络侧便可根据这个最小能力要求，进行相应的调度。而对终端来说，只要完成最小能力要求即可，如果有更快的调整能力，也是允许的。
基于前述各信息的描述，考虑到在通信网络中，一般是由网络侧设备负 责进行所有功能的控制，因此网络侧设备可以根据自身的算法和需求，对终端的上报状态或上报信息等进行配置，例如，所述网络侧设备是否支持载波特征信息上报、是否支持变更能力信息上报、是否支持时域周期信息上报(包括静态指示或动态指示信息)、是否支持用于时域周期信息的动态指示的资源配置等。相对应的，对于终端来说，需要在网络侧设备的配置和许可之下进行相应信息的上报。
对此，作为一种实现方式，所述网络侧设备可根据自身的算法和需求，向终端发送目标配置信息，而该目标配置信息用于向所述终端指示所述网络侧设备支持或不支持所述终端上报所述多播业务的相关信息，和/或，所述网络侧设备支持或不支持所述终端上报所述第一指示信息。那么，所述终端在接收到所述网络侧设备发送的目标配置信息后，根据所述目标配置信息执行对应的上报操作。
也就是说，所述终端上报所述多播业务的相关信息、所述第一指示信息是基于所述网络侧设备的“功能开关”实现，而对于“功能开关”的开关状态，可通过所述目标配置信息通知所述终端，以确保所述终端与所述网络侧设备对所述“功能开关”的开关状态的理解一致，进而使得所述终端可以按需上报，如当所述“功能开关”的开关状态为关闭时，所述终端不进行对应上报。
示例性的，在所述目标配置信息用于向所述终端指示所述网络侧设备支持或不支持所述终端上报所述多播业务的相关信息的情况下，所述目标配置信息可以包括以下(51)-(52)中的任一项。
(51)所述网络侧设备不支持多播业务的载波特征信息、变更能力信息、时域周期信息以及业务调整能力信息的上报。对应的，所述终端可不向所述网络侧设备发送所述多播业务的相关信息，以及根据所述单播业务以及所述多播业务的优先级信息确定接收所述单播业务还是所述多播业务。
例如，所述多播业务的优先级高于所述单播业务，那么所述终端接收所 述多播业务，反之亦然。
(52)所述网络侧设备支持多播业务的载波特征信息、变更能力信息、时域周期信息、业务调整能力信息中的至少一项的上报。相应的，所述可以终端向所述网络侧设备发送所述多播业务的相关信息，其中，所述多播业务的相关信息包括根据所述网络侧设备所支持的多播业务的载波特征信息、变更能力信息、时域周期信息、业务调整能力信息中的至少一项确定。
例如，如果所述网络侧设备支持多播业务的载波特征信息、能力信息，但不支持时域周期信息(相当于静态时域信息)的上报，那么，终端在需要接收或者感兴趣接收多播业务时，上报网络侧设备支持的多播业务的载波特征信息或者能力信息，但不能携带任何时域信息(即周期时域信息)。此时网络侧设备的调度行为可以在所有的时域范围之内考虑多播业务接收引起的能力缩减，从而一直以缩减的能力来进行单播业务调度。
又例如，如果所述网络侧设备支持多播业务的载波特征信息、能力信息，且支持时域周期信息(相当于静态时域信息)的上报，那么，终端可以在需要接收或者感兴趣接收多播业务时，上报网络侧设备支持的多播业务的载波特征信息或者能力信息，并携带对应的静态时域信息(即周期时域信息)，此时网络侧设备的调度行为可以在与所述静态时域信息对应的时域范围内考虑多播业务接收所引起的能力缩减，从而减少了以缩减的能力来进行单播调度的时间范围，扩大了单播调度的能力。
需要注意的是，在网络侧设备支持周期时域信息静态指示的情况下，有可能对于终端侧无法获得多播业务的DRX信息，即多播业务没有配置DRX，那么，多播业务对应的服务基站可默认在全时域范围之内都可以调度多播业务，在这种情况下，终端也无法上报对应的静态时域信息，则对单播调度的影响，同网络侧设备不支持时域信息静态指示的情况相同。
又例如，如果所述网络侧设备支持多播业务的载波特征信息、能力信息，且支持时域周期信息(相当于静态时域信息)和第一指示信息(相当于动态 时域信息)的上报，那么，终端可以在需要接收或者感兴趣接收多播业务时，上报网络侧设备支持的多播业务的载波特征信息或者能力信息，并携带对应的静态时域信息(即第一指示信息)，之后还可以根据多播业务的动态调度情况动态的向网络侧设备指示active time的扩展信息等。
此时网络侧设备的调度行为可以在终端通过第一指示信息指示的时域范围之内考虑多播业务接收引起的能力缩减，从而减少了以缩减的能力来进行单播调度的时间范围，扩大了单播调度的能力。
特别的，虽然网络侧设备同时支持动态时域信息和静态时域信息，但由于多播业务没有动态扩展active time的需求或者终端侧的一些策略(例如单播优先)，终端也可以选择仅上报静态的时域信息，因此网络侧设备调度单播业务时仅考虑静态的时域pattern即可，终端会在即便出现了active time扩展的情况下，也优先处理网络侧设备的单播调度数据。
此外，与前述多播业务的相关信息类似，对于所述第一指示信息，如果目标配置信息指示所述网络侧设备支持或不支持所述终端上报所述第一指示信息，那么，所述终端可以根据所述目标配置信息进行所述第一指示信息的上报，例如，如果所述网络侧设备不支持所述终端上报所述第一指示信息，那么，所述终端不进行所述第一指示信息的上报，又例如，如果所述网络侧设备支持所述终端上报所述第一指示信息，那么，所述终端可根据自身需求向所述网络侧设备上报所述第一指示信息。
本实施例中，终端通过上报多播业务的相关信息，使得网络侧设备可以根据多播业务的接收情况灵活的调整单播业务的调度传输，确保了两类业务的协同工作，使得在兼顾资源效率的基础上提升了UE接收性能，避免了二者接收之间的相互影响引起的接收体验变差。
如图4所示，为本申请一示例性实施例提供的多播业务的传输方法400的流程示意图，该方法可以但不限于由网络侧设备执行，具体可由安装于网络侧设备中的硬件和/或软件执行。本实施例中，所述方法400至少可以包括 如下步骤。
