相关申请的交叉引用
本申请基于申请号为201610962289.4、申请日为2016年11月04日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及一种多播业务的传输方法及装置、计算机存储介质。
背景技术
在第三代合作伙伴计划的长期演进(3GPP LTE，3rd Generation Partnership Project Long Term Evolution)系统中，引入了单小区点到多点(SC-PTM，Single Cell Point-To-Multipoint)传输技术，SC-PTM技术用于实现在单小区(Single Cell)中传输点到多点的下行多媒体广播多播(MBMS，Multimedia Broadcast Multicast Service)业务。SC-PTM引入了两种逻辑信道，即单小区多播控制信道(SC-MCCH，Single Cell-Multicast Control Channel)和单小区多播传输信道(SC-MTCH，SC-MCCH，Single Cell-Multicast Traffic Channel)。在LTE中，SC-MCCH与SC-MTCH都通过物理下行共享信道(PDSCH，Physical Downlink Shared Channel)承载。
如图1所示，窄带物联网(NB-IoT，Narrow Band Internet of Thing)和LTE增强的机器类型通讯(eMTC，enhanced Machine Type Communication)中为了增强覆盖的UE的接收，同一个PDCCH信令和PDSCH信道数据都需要重复发送多次。如图1所示，在调度PDSCH的PDCCH信令中，除了指示PDSCH信道所使用的时域频域资源以及调制编码格式MCS之外，还 指示了PDSCH的重复发送次数(Repetition number)，以及调度发送PDSCH的时间起点，即调度定时scheduling delay，在现有技术中，这个调度定时是指最后一个PDCCH子帧之后的第几个无线子帧开始调度相应的PDSCH。
在NB-IoT或eMTC中，如何支持SC-PTM，存在以下的问题。
NB-IoT和eMTC引入SC-PTM的主要目的在于提供一种高效的点对多点的传输技术，主要用于海量的UE更新其软件或固件，避免海量的UE通过专用信道(dedicated channel)获取所述业务数据。这种业务显然需要100％正确可靠的接收业务数据，否则所接收到的部分业务数据没有实际的意义。而目前的业务传输方式并不能保证数据完全准确的接收。
另一方面，广播业务面对的多个接收业务的用户终端UE，不同的UE的覆盖信号质量不同，因此需要接收PDSCH的重复个数也不同，如何让覆盖信号质量好的UE尽快的接收到业务数据，从而减少电池消耗，又能满足覆盖信号不好的UE能接收到足够多的PDSCH重复发送以成功解码数据，也是需要解决的问题。

为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
实施例1
在本实施例中，提供了一种多个数据块进行交织传输的方法。
如图2所示，接入网网元将N个数据块进行联合调度传输，其中，对一个数据块的一次重复发送形成一次级别一的重复发送，对所述N个数据块分别连续重复发送M1次级别一的重复发送形成一次级别二的重复发送；M2次级别二的重复发送形成N个数据块的一次联合调度传输； N、M1、M2为正整数。
这里，将对一个数据块的一次重复发送称为一次级别一的重复发送，将对N个数据块分别连续重复发送M1次级别一的重复发送，并组成一次级别二的重复发送。M2个级别二的重复发送组成一次完整的联合调度传输。
具体的，一个数据块的一次重复发送(也即一次级别一的重复发送)为：占用一个无线子帧的PDSCH发送，则N个数据块分别连续重复M1个无线子帧的重复发送组成了一个级别二的重复发送，M2个连续的级别二的重复发送组成了这N个数据块的一次完整调度传输。
接入网网元通过动态调度方式调度此N个数据块的联合调度传输时，接入网网元通过下列方式之一指示调度信息：
1、接入网网元通过动态调度信令DCI指示进行联合调度的数据块的个数N，并通过DCI或者半静态信令指示上述级别二的重复发送的次数M2，或一次调度传输一共占用的无线子帧的数量信息。
2、接入网网元通过半静态调度信令指示进行联合调度的数据块的个数N，并通过DCI或半静态信令指示上述级别二的重复发送的次数M2，或一次调度传输一共占用的无线子帧的数量信息。
接入网网元通过半静态调度方式调度此N个数据块的联合调度传输时，接入网网元在半静态信令中指示进行联合调度的数据块的个数N，以及上述的级别二重复次数M2或一次调度传输一共占用的无线子帧的数量信息。
在一实施方式中，接入网网元还通过动态调度信令DCI或半静态信令指示上述级别一的重复次数M1。缺省的，M1的值为1，即对所述N个数据块分别发送一次级别一的重复形成一次级别二的重复发送。
在上述的方法中，如果指示了级别二的重复发送的次数M2，则一次完 整的调度传输中PDSCH所占用的无线子帧的个数＝M2×N×M1，如果指示了一次调度传输一共占用的无线子帧的个数T，则所述的M2＝T/(N×M1)。这里假设级别一的一次重复发送占用一个无线子帧，如果级别一的一次重复发送占用多个无线子帧，则相应的将此因素加入到上述的公式中即可。
上述的半静态信令包括SC-MCCH消息，此时接入网网元在SC-MCCH消息中某个特定业务的调度信息中指示上述信息。
在不同的需求中，可以选择不同的信令指示方式，并达到不同的有益效果。
例如通过动态调度信令DCI指示上述的N，具有完全的动态调度性能，接入网网元可以根据调度数据时等待调度的和数据块的个数决定N的个数，但获得了灵活性的同时带来DCI的开销的增加。
接入网网元通过动态调度信令DCI指示上述的M2或一次调度所占的子帧的个数，同样具有最大的灵活性，但同样也带来DCI开销的增加。
对一次需要调度发送的数据块的个数已经确定且在一段时间不发生变化的场景，使用半静态信令指示上述信息更合适。例如，SC-PTM中的SC-MCCH消息在RLC层分片后，分为N个RLC PDU，即N个数据块，且SC-MCCH消息大小在一定时间内不会发生变化，则可以使用半静态的信令SIB20指示调度SC-MCCH消息的数据块时所使用的上述N和M2等信息。
而通过半静态信令指示上述的N时，如果需要调度的数据块的个数少于N，则需要下列的方法进行解决：
接入网网元在调度时，如果需要调度发送的数据块的个数少于通过信令指示的信令N，则接入网网元通过制造不包含数据的伪数据块与需要发送的数据块共同组成N个数据块。且这些不包含数据块的伪数据块排列在需要发送的数据块之后发送。这些伪数据块为数据部分只包含pading的 RLC PDU或MAC PDU。
在本实施例中所述的数据块，其形式包括RLC PDU，MAC PDU，或MAC层传输块(TB)。
通过本实施例的方法，接入网网元实现了对多个数据块进行调度时的交织传输。并通过信令的指示，实现动态的调整进行联合调度的数据块的个数。在这种传输方式下，信号覆盖好的UE可以尽快的接收到N个数据块，而信号不好的UE也有足够多的接收机会将上述N个数据块的多次重复进行合并(combining)来实现成功的解码。
实施例2
本实施例提供了一种对N个数据块进行多次重复调度传输的方法。
接入网网元调度传输业务或信令无线承载(SRB，Signaling Radio Bearer)时，为其配置多次传输周期(MTP，Multiple Transmission Period)，并在所述的MTP中联合调度传输所述N个数据块一次或多次，其中，对一个数据块的一次重复发送形成一次级别一的重复发送，对所述N个数据块分别连续重复发送M1次级别一的重复发送形成一次级别二的重复发送；M2次级别二的重复发送形成N个数据块的一次联合调度传输；
N、M1、M2为正整数。
所述接入网网元配置多次传输周期MTP，至少包括：所述MTP的长度信息L。在一实施方式中，还包括所述MTP的起始位置的偏移信息Offset。
所述一个MTP的起始位置通过下述公式计算：

其中：H-SFN为系统超帧号，SFN为系统帧号，mod为取模运算符号，L为MTP的长度，offset为MTP起始位置的偏移。所述MTP的起始位置为满足上述公式的H-SFN以及SFN；所述offset的缺省值为0。
在一实施方式中，接入网网元在所述的MTP中发送用于调度所述业务 或SRB的数据块的动态调度信令。如果所述业务或SRB有调度周期或重复周期，或更进一步，所述业务或SRB配置用于调度的时间窗口，则接入网网元在所述MTP中上述业务或SRB的调度周期或重复周期，以及其配置的调度时间窗口内发送所述业务或SRB的动态调度信令。
接入网网元以MTP重复模式调度所述多个数据块，所述MTP重复模式用于将N个数据块在多个MTP中重复调度传输，所述MTP重复模式的信息至少包括：用于调度传输所述N个数据块的MTP的个数M、以及用于调度传输所述N个数据块的多个MTP中相邻两个MTP之间的间隔长度P，其中M的取值范围为大于等于1的正整数，P的取值为大于等于1的正整数，所述的相邻MTP的间隔为相邻两个MTP的起始位置之间的间隔长度，或相邻两个MTP中前一个MTP的结束位置与后一个MTP起始位置的间隔长度。
在一实施方式中，所述的相邻两个MTP的间隔长度P的单位为MTP的个数，此时所述多个MTP中相邻两个MTP间的间隔为P个MTP的长度。
所述的N个数据块在上述的多个MTP中被重复的调度传输，即，在每个MTP中，所述的N个数据块被调度传输一次或多次。在一个MTP内，接入网网元调度所述的N个数据块一次或多次，具体的调度方式包括但不限于：
1、分别独立的调度每个数据块，即承载一个数据块的PDSCH信道一次或多次重复通过独立的PDCCH信令DCI进行调度。
2、一个PDCCH信令DCI调度N个数据块的PDSCH信道。
3、使用本发明中实施例1提供的N个数据块的联合调度方法进行调度传输。
在一实施方式中，在一个MTP中，每个数据块可以被调度传输N2次，N2大于等于1。
接入网一个MTP中调度N个数据块的N2次传输时，其调度的顺序包括：
1、每个数据块被调度传输N2次后调度下一个数据块；即按照(数据块1，数据块1…)，(数据块2，数据块2…)…(数据块N，数据块N…)
2、N个数据块被依次调度一次作为一个重复，即接入网按照(数据块1，数据块2…数据块n)，(数据1，数据2…数据n)…的方式调度传输N2次；
在一实施方式中，在动态调度所述N个数据块的动态调度信令DCI中，指示当前的调度所在MTP为调度所述N个数据块的M个MTP中的顺序号，或在当前MTP之后(包括或不包括当前的MTP)用于调度传输所述的N个数据块的MTP的个数。
当在每个MTP中一个数据块只被调度传输一次时，所述的MTP的顺序号等同于所述数据块被调度的顺序号，所述的MTP的个数等用于所述数据块被调度传输的次数。
在一实施方式中，如果所述的在一个MTP中调度传输的数据块的个数N大于1，则接入网网元还在调度数据块的DCI中的指示数据块的标识Data-ID，同一个数据块在不同MTP中传输时有相同的标识Data-ID。
在一实施方式中，所述的数据块的标识Data-ID为一个数据块在所述N个数据块中的顺序号，即所述N个数据块中的第一个数据块的标识为0，第二个数据块的标识为1，以此类推。

所述接入网网元至少包括3GPP协议定义的增强基站eNB。
如图3所示，在图3中，接入网网元配置MTP的长度L以及起始位的偏移O。并指示MTP的重复模式为：MTP的重复个数M为3，每个MTP中调度的不同的数据块的个数为2，即数据块1和2，并指示调度数据1和2的相邻两个MTP间的间隔为2个MTP，或者说调度数据1和2的MTP重复周期为2个MTP。
接入网网元在任意一个MTP，在图3中，标识为MTP n的MTP开始调度传输数据块1和2，并在随后的MTP n+2，以及MTP N+4中重复调度数据块1和2。
UE根据解码的需要决定接收数据块1和2在上述MTP的调度传输。
接入网网元在MTP n中，通过DCI指示当前MTP的顺序号为调度数据块1和2的第一个MTP，用0或者1表示，并以此类推，则MTP n+1和MTP n+2中，通过DCI指示当前MTP的顺序号为第二和第三个MTP。
在任意时刻开始接收该业务的UE根据上述指示的MTP的顺序号知道当前的MTP的顺序号，以及根据调度数据块1和2的MTP的个数M，知道在此MTP之后还有哪些MTP调度传输数据块1和2，例如UE在MTP n+2开始接收数据，UE根据MTP n+2中所述调度数据块1或2的DCI指示的当前MTP顺序号2，以及调度数据块1和2的MTP的个数M为3，以及调度数据块1和2的MTP的间隔为2个MTP，可以知道后续的MTP n+4中调度的是数据块1和2。从而UE并不会因为没有接收到第一个调度数据块1和2的MTP而不能和接入网的发送保持对齐，接入网网元也得以在任何MTP开始调度数据块1和2，而不需要额外的机制让UE知道调度数据块1和2的开始MTP位置。
如果UE在MTP n+2中已经成功解码数据块1和2，则UE可以忽略在 MTP n+4中传输的数据，如果UE在MTP n+2中没有解码数据块1或2，则UE可以继续在MTP n+4中读取数据块1和2的调度传输，并通过调度数据块的DCI中指示的数据块的标识来识别调度传输的是哪一个数据块，从而可以将MTP n+4中接收到的数据块1或数据块2的PDSCH信道信号，和在MTP n+2中接收到的相应的数据块1或数据块2的PDSCH信道信号进行合并解码。
本实施例以数据块1和2的调度发送为例，在其它的MTP中，接入网网元还可以调度同一个业务或SRB的其它数据块。
图4为本实施例另一个优选的具体实施方式，在这个例子中，一个MTP只调度一个数据块，在图中标记为1，在一个MTP中，数据块1被调度传输2次。在每个MTP中，接入网网元通过调度数据块1的DCI指示当前MTP为用于调度数据块1的MTP中的顺序号。在图中MTP n中发送的用于调度该业务或SRB的DCI指示当前MTP的顺序号为第一个MTP，或指示当前MTP之后还有2个MTP用于传输和当前MTP相同的数据块。以此类推，在MTP n+2和MTP n+4中，所述的DCI分别指示当前MTP为第二个和第三个MTP。
图5为本实施例的第三个优选的具体实施方式，在这个例子中，一个MTP中调度传输2个数据块，每个数据块被调度传输2次。在图5中，MTPn和MTP n+2用于调度传输数据块1和数据块2。在一个MTP中，数据块1和数据块2分别被连续调度2次。即N＝2，N2＝2。接入网网元在调度数据块1和数据块2的DCI中分别指示其数据块标识为0和1，用于区别二者。

调度单元60，配置为将N个数据块进行联合调度传输，其中，对一个 数据块的一次重复发送形成一次级别一的重复发送，对所述N个数据块分别连续重复发送M1次级别一的重复发送形成一次级别二的重复发送；M2次级别二的重复发送形成N个数据块的一次联合调度传输；N、M1、M2为正整数。
