具体实施方式
为了更好地理解本申请的实施例的上述目的、方案和优势，下文提供了详细描述。该详细描述通过使用框图、流程图等附图和/或示例，阐明了装置和/或方法的各种实施方式。在这些框图、流程图和/或示例中，包含一个或多个功能和/或操作。本领域技术人员将理解到：这些框图、流程图或示例内的各个功能和/或操作，能够通过各种各样的硬件、软件、固件单独或共同实施，或者通过硬件、软件和固件的任意组合实施。
首先，为了便于对本申请的实施例的理解，首先介绍一下目前SC-PTM技术的实现。
首先，基站会针对进行多播业务数据传输的每一个小区分配组-无线网络临时标识(Group-Radio Network Temporary Identifier，G-RNTI)，并预先通知终端设备多播业务和G-RNTI的对应关系。
在进行多播业务的传输时，基站在调度信息中包括传输的多播业务对应的G-RNTI，终端设备根据收到的调度信息中的G-RNTI，确定该多播业务被调度，并根据调度信息接收该多播业务的数据包。
图1示出了基站同时进行两个多播业务传输时的情形。基站为多播业务1分配G-RNTI 1，为多播业务2分配G-RNTI 2。终端设备在收到的调度信息中包括G-RNTI 1时，确定多播业务1被调度，根据收到的调度信息接收多播业务1的数据包。终端设备在收到的调度信息中包括G-RNTI 2时，确定多播业务2被调度，根据收到的调度信息接收多播业务2的数据包。
其中，基站在物理下行共享信道(Physical Downlink Share Channel， PDSCH)上发送多播业务的数据包。区别于承载单播业务的数据的PDSCH，承载多播业务的PDSCH称为多播PDSCH。
此外，基站在物理下行控制信道(Physical Downlink Control Channel，PDCCH)上发送多播业务的调度信息，即下行控制信息(Downlink Control Information，DCI)。UE根据该DCI包括的调度信息接收多播PDSCH。
对于采用SC-PTM技术的多播业务的数据传输，基站可以配置DCI的格式为DCI格式(Format)1A，DCI Format 1A用于连续资源块(Resource Block，RB)的分配。
SC-PTM技术中引入了两个逻辑信道，如图2所示，分别为：单小区-多媒体广播多播业务控制信道(Single Cell-Multimedia Broadcast Multicast Service Control CHannel，SC-MCCH)和单小区-广播多播业务业务信道(Single Cell-Multimedia Broadcast Multicast Service Service CHannel，SC-MTCH)。
其中，SC-MCCH用于发送控制信息，包含SC-MTCH的配置信息，比如：SC-MTCH对应的G-RNTI以及非连续接收(Discontinuous Reception，DRX)参数。SC-MCCH周期性发送控制信息。
SC-MTCH用于传输多播业务的数据包，每个多播业务对应一个SC-MTCH信道。SC-MTCH可以被配置为连续传输，比如：图2中的多播业务3；也可以被配置为非连续传输，比如：图2中的多播业务1和多播业务2。图2中，对于MTCH，高位表示有多播业务的数据在发送，低位表示没有多播业务的数据包发送；对于MCCH，高位表示有多播业务的控制信息在发送，低位表示没有多播业务的控制信息在发送。
本申请的实施例可以基于目前的SC-PTM技术进行改进，也可以应用于其他传输多播业务的无线通信系统。
下面，介绍本申请的实施例可应用的无线通信系统。
如图3所示，该无线通信系统可包括：终端设备301、接入网设备302和多播业务配置设备303。
终端设备301位于接入网设备302的覆盖下，可接收来自接入网设备302 的多播业务的数据包。
接入网设备302下有至少一个小区，其中包括第一小区，还可包括其他小区。或者，第一小区也可不是接入网设备302下的小区。接入网设备302可控制第一小区所属的基站等设备发送多播业务在第一小区发送时使用的配置的信息，以及在第二小区发送时使用的配置的信息。
终端设备301位于第一小区内。第一小区周围还存在至少一个第二小区，这些第二小区组成第二小区集合，第二小区可属于接入网设备302，也可属于其他接入网设备。
其中，第二小区可以被配置为第一小区的邻小区，比如：通过诸如接入网设备302等网络设备进行数据配置，将第二小区配置为第一小区的邻小区。第二小区也可以不被配置为第一小区的邻小区。无论是否被配置为第二小区的邻小区，只要终端设备301接收到的来自第二小区的多播业务的信号质量足够好，终端设备301就有可能从该第二小区进行多播业务的数据包的合接收。
多播业务配置设备303用于下发多播业务的一些配置信息。多播业务配置设备303可连接一个或多个接入网设备，分别向这些接入网设备下发多播业务的配置信息，用于接入网设备按照配置信息在其下的小区内进行多播业务的传输。比如：多播业务配置设备303可为多小区/多播协调实体(Multi-cell/multicast Coordination Entity，MCE)。
当然，无线通信系统中还可包括其他终端设备，这里为了示意简单，图中并未画出。
该无线通信系统可采用的通信制式可包但不限于：全球移动通信系统(Global System of Mobile communication，GSM)、码分多址(Code Division Multiple Access，CDMA)IS-95、码分多址(Code Division Multiple Access，CDMA)2000、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)、时分双工-长期演进(Time Division Duplexing-Long Term  Evolution，TDD LTE)、频分双工-长期演进(Frequency Division Duplexing-Long Term Evolution，FDD LTE)、长期演进-增强(Long Term Evolution-Advanced，LTE-advanced)、个人手持电话系统(Personal Handy-phone System，PHS)、全球微波互联接入(Worldwide Interoperability for Microwave Access，WiMAX)，以及未来演进的各种无线通信制式。
该无线通信系统还可以为未来演进的第五代(the 5th Generation，5G)无线通信系统。
其中，终端设备301可以是无线终端，无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。例如，个人通信业务(PCS，Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(PDA，Personal Digital Assistant)等设备。无线终端也可以称为订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户设备(User Equipment)。
接入网设备302可包括基站，或用于控制基站的无线资源管理设备，或包括基站和用于控制基站的无线资源管理设备；其中基站可为宏站或小站，比如：小小区(small cell)、微小区(pico cell)等，基站也可为家庭基站，比如：家庭节点B(Home NodeB，HNB)、家庭演进节点B(Home eNodeB，HeNB)等，基站也可包括中继节点(relay)等。
比如：对于TDD LTE、FDD LTE或LTE-A等LTE系统，本申请提供的无线通信系统中的接入网设备302可为演进节点B(evolved NodeB，eNodeB)，终端设备301可为UE；对于TD-SCDMA系统或WCDMA系统，本申请提供 的无线通信系统中的接入网设备302可包括：节点B(NodeB)和/或无线网络控制器(Radio Network Controller，RNC)，终端设备301可为UE；对于GSM系统，本申请提供的中的接入网设备302可包括基站收发台(Base Transceiver Station，BTS)和/或基站控制器(Base Station Controller，BSC)，终端设备301为移动台(Mobile Station，MS)；对于WiFi系统，接入网设备302可包括：接入点(Access Point，AP)和/或接入控制器(Access Controller，AC)，终端设备301可为站点(STAtion，STA)。再比如：对于未来演进的5G系统，接入网设备302可以为接入网中的节点。
图4示出了多播业务配置设备303、接入网设备302和终端设备301交互的流程图。
该流程中，以多播业务A为例加以说明。
终端设备301当前所在的小区为第一小区，第一小区属于接入网设备302。
第一小区周围有至少一个第二小区，组成第二小区集合。其中，第二小区可以为第一小区的邻小区，比如：由接入网设备302配置为第一小区的邻小区。
该流程中，接入网设备302不仅向终端设备301发送多播业务A在第一小区发送时使用的配置的信息(称为“第一配置信息”)，还向终端设备301发送多播业务A在每一个第二小区发送时使用的配置的信息(称为“第二配置信息”)。其中，一个第二配置信息对应一个第二小区。
这样，终端设备301不仅能够获知自身所在的小区的多播业务A的配置，还能够知道其他小区的多播业务A的配置。按照获知的各个小区的多播业务A的配置，可进行多播业务A的合并接收，有效提高了多播业务A的接收质量。
下面，详细介绍该流程。该流程包括如下步骤：
S401：多播业务配置设备303向接入网设备302发送多播业务A的配置信息，用于接入网设备302在其下的小区内，按照该配置信息发送多播业务的数据包。
该步骤中，多播业务配置设备303还可向其他接入网设备发送多播业务A的配置信息，收到该配置信息的各接入网设备都按照该配置信息进行多播业务A的发送，使得这些接入网设备覆盖下的终端设备可实现多播业务A的合并接收。
可选地，该配置信息可包括：块长信息，用于描述多播业务A在空口发送时使用的传输块的长度。收到该配置信息的接入网设备在其下的各个小区内进行多播业务A的传输时，发送的传输块的长度均为该块长信息所描述的传输块的长度。
S402：接入网设备302确定第一配置信息。
S403：接入网设备302在第一小区内发送第一配置信息。
S404：接入网设备302针对第二小区集合中的每一个第二小区，分别确定该第二小区对应的第二配置信息。
具体的，可选，如果第二小区不属于接入网设备302，则接入网设备302可以通过MCE获取第二小区对应的第二配置信息，或者通过和第二小区所属的接入网设备之间的接口从第二小区所属的接入网设备获取第二小区对应的第二配置信息。
S405：接入网设备302在第一小区内发送每一个第二小区对应的第二配置信息。
无论是第一小区还是第二小区，接入网设备302确定的多播业务A的配置信息均可包括下列信息中的一项或多项：
信息一、多播业务A在小区内的调度标识
该调度标识置于多播业务A的调度信息中发送，用于终端设备301获知多播业务A在该小区内被调度。
比如：当基于SC-PTM技术实现时，该调度标识可为G-RNTI，调度信息可为DCI。这里，将第一小区所使用的调度标识称为“第一调度标识”，将第二小区所使用的调度标识称为“第二调度标识”。
信息二、小区的DRX参数
该DRX参数用于描述多播业务A在小区内是如何非连续发送的。终端设备301根据该DRX参数进行非连续接收。
需要说明的是，并不是第一小区和第二小区集合中的所有小区都进行多播业务A的非连续发送，因此，该DRX参数并不是对于每一个小区都必选。只有进行非连续发送的小区，才会有DRX参数。
信息三、多播业务A的偏置信息
用于描述多播业务A在第二小区发送时与在第一小区发送时所具有的时间偏差。
一种可能的情况是，无线通信系统中的多个接入网设备之间进行了时间同步，若多播业务A在多个接入网设备中的小区内是同步发送的，此时，接入网设备302不需要向终端设备301通知该信息。
另一种可能的情况是，各个小区以约定的时间偏差发送多播业务A，且终端设备301预先知道了各小区发送多播业务A时的时间偏差关系，此时，接入网设备302也不需要向终端设备301通知该信息。
若各个小区之间，多播业务A是非同步发送的，且终端设备301无法获知各小区之间发送多播业务A时的时间偏差关系，则接入网设备302需要向终端设备301发送该信息。
信息四、多播业务A的接收门限的信息
该接收门限的信息用于终端设备301从第二小区集合中选择合并接收多播业务A的第二小区。
接入网设备302在第一小区内发送的配置信息并不仅限于上述信息。只要是用于终端设备301接收多播业务A的信息，都可以作为配置信息发送给终端设备301。比如，配置信息还可包括：多播业务A的业务标识信息，第二小区的小区标识信息等。
上述配置信息可在MCCH中发送给终端设备301。上述配置信息可通过一条或多条消息发送给终端设备301。
上述步骤S401、S402和S404之间没有绝对的先后关系，比如：可先执 行步骤S402和步骤S403，再执行步骤S401，S404和S405；也可先执行步骤S404、S405，再执行S402、S403，最后执行S401。
S406：终端设备301从第二小区集合中选择进行合并接收的第二小区。
其中，终端设备301可针对第二小区集合中的部分或全部第二小区，对收到的来自该第二小区的信号进行测量，该信号可为参考信号，比如：小区特定参考信号(Cell-Specific Reference Signal，CRS)。
终端设备301按照测量结果，从第二小区集合中选择合并接收多播业务的第二小区。终端设备301选择第二小区的方式可包括但不限于如下方式：
方式一、选择测量结果最好的N个小区
方式一种，终端设备301支持同时接收多播业务A的邻小区的个数为N，N为正整数，则终端设备301可从第二小区集合中，选择N个小区作为合并接收多播业务A的小区。
如果第二小区集合中包括M个小区，终端设备301针对M个小区中的P个小区进行测量，得到了P个测量结果，P为正整数，不大于M且大于N，则终端设备301可从P个第二小区中，选择测量结果最好的前N个第二小区，作为合并接收多播业务A的小区。
方式二、按照门限选择第二小区
同样地，终端设备301针对M个小区中的P个小区进行测量，得到了P个测量结果，终端设备301选择测量结果大于门限的第二小区，作为合并接收多播业务A的第二小区。
其中，该门限可以是预先设置在终端设备301中，也可以是终端设备301根据步骤S402中收到的多播业务A的接收门限的信息确定的。
S407：终端设备301针对多播业务A的同一数据内容，按照第一配置信息从第一小区，以及按照第二配置信息从对应的选择的合并接收多播业务A的第二小区，合并接收多播业务A的数据包。
其中，如前所述，若第一小区和第二小区集合中的小区是同步发送多播业务A的数据包的，则终端设备301可确定第一小区和第二小区集合中的小 区在同一时刻发送的数据包为针对同一数据内容发送的数据包。
或者，若各个小区以约定的时间偏差发送多播业务A，且终端设备301预先知道各小区发送多播业务A的时间偏差关系，则终端设备301可确定满足该时间偏差关系的数据包为针对同一数据内容发送的数据包。
再或者，各个小区之间，多播业务A是非同步发送的，终端设备301从接入网设备接收了前述的偏置信息，该偏置信息用于描述多播业务A在第二小区发送时与在第一小区发送时所具有的时间偏差，终端设备301根据该偏置信息确定该偏置信息对应的与第一小区发送多播业务A的同一数据内容的数据包时具有的时间偏差，并根据该偏置信息，确定第一小区和偏置信息对应的第二小区中发送的多播业务A的数据包中，哪些数据包是同一数据内容的数据包。
终端设备301在从第一小区接收多播业务A的数据包时，可接收来自第一小区的调度信息，并在来自第一小区发送的调度信息中包括第一调度标识时，获知多播业务A在第一小区内被调度；终端设备301按照来自第一小区的调度信息接收来自第一小区的多播业务A的数据包。
类似地，终端设备301在从一个第二小区接收多播业务A的数据包时，可接收来自该第二小区的调度信息，并在来自该第二小区的调度信息中包括第二调度标识时，获知多播业务A在该第二小区内被调度，终端设备301按照来自该第二小区的调度信息接收来自该第二小区的多播业务A的数据包。
若第一配置信息包括多播业务A在第一小区发送时所使用的非连续接收DRX参数，则终端设备301在从第一小区接收多播业务A的数据包时，可按照多播业务A在第一小区发送时所使用的DRX参数，对来自第一小区的多播业务A的数据包进行非连续接收。
若第二小区的第二配置信息包括多播业务A在该第二小区发送时所使用的DRX参数，则终端设备301在从该第二小区接收多播业务A的数据包时，可按照多播业务A在该第二小区发送时所使用的DRX参数，对来自该第二小区发送的多播业务A的数据包进行非连续接收。
终端设备301在针对多播业务A的同一数据内容，合并接收多播业务A的数据包时，可仅按照第一配置信息从第一小区接收多播业务A的数据包；或者仅按照一个或多个第二小区的第二配置信息，分别从对应的选择的合并接收多播业务A的第二小区接收多播业务A的数据包；再或者，终端设备301既从第一小区，也从选择的合并接收多播业务A的第二小区接收多播业务A的数据包。
下面，给出终端设备301合并接收同一数据内容的多播业务A的数据包的几种可选方式：
方式一
终端设备301针对多播业务A的同一数据内容，按照第一配置信息从第一小区接收多播业务A的数据包；
终端设备301对从第一小区接收的多播业务A的数据包进行解码，若解码正确，则停止从对应的选择的合并接收多播业务A的第二小区接收多播业务A的数据包。可选地，若终端设备301对从第一小区接收的多播业务A的数据包进行解码错误，则终端设备301从对应的选择的合并接收多播业务A的第二小区接收多播业务A的数据包。
比如：终端设备301在从第一小区接收数据包和尝试解码的过程中，即开始从第二小区接收数据包，那么，当终端设备301对从第一小区接收的数据包解码正确时，则终止从第二小区接收数据包的操作，已接收到的数据包可以丢弃；当终端设备301对从第一小区接收的数据包解码错误时，终端设备301继续从第二小区接收数据包。
再比如：终端设备301对从第一小区接收的数据包完成解码之后，才根据解码的结果，决定是否从第二小区接收数据包。若解码正确，则不会从第二小区接收数据包；若解码错误，则才从第二小区接收数据包。
方式二
终端设备301针对多播业务A的同一数据内容，从第三小区接收多播业务A的数据包；
其中，第三小区为第一小区和终端设备301选择的合并接收多播业务A的第二小区中最先发送同一数据内容的数据包的小区；
终端设备301对从第三小区接收的多播业务A的数据包进行解码，若解码正确，则停止从其他小区接收多播业务A的数据包；其他小区为：包括第一小区和第二小区集合中的小区在内的多个小区中、除了第三小区之外的至少一个小区。可选地，若终端设备301对从第三小区接收的多播业务A的数据包进行解码错误，则终端设备301从其他小区接收多播业务A的数据包。
比如：终端设备301在从第三小区接收数据包和尝试解码的过程中，即开始从其他小区接收数据包，那么，当终端设备301对从第三小区接收的数据包解码正确时，则终止从其他小区接收数据包的操作，已接收到的数据包可以丢弃；当终端设备301对从第三小区接收的数据包解码错误时，终端设备301继续从其他小区接收数据包。
再比如：终端设备301对从第三小区接收的数据包完成解码之后，才根据解码的结果，决定是否从其他小区接收数据包。若解码正确，则不会从其他小区接收数据包；若解码错误，则才从其他小区接收数据包。
方式三
终端设备301针对多播业务A的同一数据内容，按照第一配置信息从第一小区接收多播业务A的数据包；并且
终端设备301从对应的选择的合并接收多播业务A的第二小区接收多播业务A的数据包。
S408：终端设备301将合并接收的多播业务A的同一数据内容的数据包进行合并。
可选地，终端设备301可将合并接收的多播业务A的同一数据内容的数据包进行HARQ合并。
下面列举HARQ合并技术的两种实现方式：
一、软合并(Chase Combine，CC)
在通信过程中，终端设备可能会接收到错误的数据包时，虽然这些错误 数据包不能够独立地正确译码，但是它们依然包含有一定的信息。软合并就是利用这部分信息，即是将接收到的错误的数据包保存在存储器中，与重传的数据包合并在一起进行译码，提高了传输效率。
二、增量冗余(Incremental Redundancy，IR)
增量冗余(Incremental Redundantcy，IR)技术是通过在第一次传输时发送信息比特(bit)和一部分冗余bit，而通过重传(Retransmission)发送额外的冗余bit。如果第一次传输没有成功解码，则可以通过重传更多冗余bit降低信道编码率，从而提高解码成功率。如果加上重传的冗余bit仍然无法正常解码，则进行再次重传。随着重传次数的增加，冗余bit不断积累，信道编码率不断降低，从而可以获得更好的解码效果。
或者，终端设备301从合并接收的多播业务A的同一数据内容的数据包中选择一个正确解码的数据包。
下面，以图5和图6所示的场景为例，对图4所示的流程进一步举例说明。
图5示出了图3所示的无线通信系统的一个例子。图5所示的系统包括：
广播多播服务中心(Broadcast Multicast Service Center，BMSC)，用于启动多播业务，并将需要启动多播业务的小区的小区标识发送给移动性管理实体(Mobility Management Entity，MME)，并通过MME发送给MCE(前述的多播业务配置设备303的一个例子)。
MCE，在决定启动多播业务的传输后发送通知给基站(前述的接入网设备302的一个例子)，通知基站启动多播业务的传输。
多媒体广播多播业务-网关(Multimedia Broadcast Multicast Service，MBMS-GW)，接收来自BMSC的多播业务的数据，并将收到的多播业务的数据发送给基站。
基站，将多播业务的数据承载在PDSCH上发送给UE。本申请的实施例中主要涉及启动多播业务的传输后如何将多播业务的配置信息发送给UE(终端设备301的一个例子)。
图7为该例子的流程图。如图7所示，该流程包括如下步骤：
S701：MCE向基站发送多播业务1(前述的多播业务A的一个例子)的配置信息。
其中，该配置信息包括进行多播业务1播放的小区的小区标识信息，还可包括前述的块长信息。
S702：基站通过第一小区向UE发送多播业务1的配置信息(包括前述的第一配置信息和第二配置信息)。
基站将配置信息承载于SC-MCCH中发送给UE。
配置信息中包括多播业务1在第一小区内发送时所使用的配置的信息，包括如下信息中的一个或多个：
多播业务1的业务标识信息，比如：临时移动组标识(Temporary Mobile Group Identity，TMGI)；
基站在第一小区内调度多播业务1时使用的RNTI，称为“第一G-RNTI”(前述的第一调度标识的一个例子)；
多播业务1在第一小区内传输时使用的DRX参数。
配置信息中还包括多播业务1在邻小区(即前述的第二小区)传输时所使用的配置的信息，包括如下信息中的一个或多个：
邻小区的小区标识信息；
多播业务1在邻小区被调度时所使用的RNTI，称为“第二G-RNTI”(前述的第二调度标识的一个例子)；
邻小区的偏置信息；
多播业务1在邻小区传输时使用的DRX参数。
S703：UE选择选择合并接收多播业务1的小区(即从前述的第二小区集合中选择小区)。
其中，UE确定支持当前的多播业务1传输的邻区的配置信息，并对这些邻区进行测量，当测量结果高于一定门限(比如：前述的多播业务1的接收门限)时，选择该邻区作为合并接收多播业务1的小区。
参考图6，UE位于小区1、小区2和小区3的交界处，即共同覆盖的区域内，当前的服务小区为小区2。多播业务1在小区2中使用G-RNTI 1进行调度，在小区1中使用G-RNTI 2进行调度，在小区3中使用G-RNTI 3进行调度。
UE根据基站发送的多播业务1的配置信息(包括前述的第一配置信息和第二配置信息)知道多播业务1也在小区1和小区3内发送。
UE对小区1和小区3进行测量，如果小区1和小区3的测量结果高于一定门限(比如：前述的多播业务1的接收门限)，则将小区1、小区2和小区3作为合并接收多播业务的小区。
S704：基站向UE发送多播业务的数据包。
基站在MCE发送的小区标识所指定的小区内，向UE发送多播业务的数据包，以便UE对多播业务的数据包进行合并接收。
可选的，如果MCE发送了前述的块长信息，则基站按照该块长信息所指定的传输块的长度，发送多播业务的数据包，以保证同一多播业务在不同小区发送时使用相同长度的传输块进行多播业务的传输。
S705：UE通过步骤S703中确定的合并接收多播业务的小区，对在各小区发送的多播业务1同一数据内容的数据包进行接收，并将接收到的数据包进行合并。
具体地，首先，UE根据小区2的配置信息(前述的第一配置信息的一个例子)接收小区2内发送的多播业务1的该同一数据内容的数据包；然后，UE分别根据小区1和小区3的配置信息(前述的第二配置信息的一个例子)接收小区1和小区3内发送的多播业务1的该同一数据内容的数据包。
可选的，如果UE在小区内接收的数据包读取正确，则停止接收小区1和小区3内发送的数据包。
可选地，UE可根据步骤S702中基站发送的小区1和小区3的偏置信息，确定同一数据内容的数据包，并将同一内容的数据包进行合并。
