具体实施方式
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地说明本申请实施例的技术方案，并不构成对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。
请参考图1，其示出了本申请实施例提供的一种无线通信***的结构示意图。如图1所示，无线通信***是基于蜂窝移动通信技术的通信***，该无线通信***可以包括：若干个终端110以及若干个基站120。
其中，终端110可以是指向用户提供语音和/或数据连通性的设备。终端110可以经无线接入网(Radio Access Network，RAN)与一个或多个核 心网进行通信，终端110可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、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、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端110也可以是无人飞行器的设备。或者，终端110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信***中的网络侧设备。其中，该无线通信***可以是***移动通信技术(the 4th generation mobile communication，4G)***，又称长期演进(Long Term Evolution，LTE)***；或者，该无线通信***也可以是5G***，又称新空口(new radio，NR)***或5G NR***。或者，该无线通信***也可以是5G***的再下一代***。其中，5G***中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站120可以是4G***中采用的演进型基站(eNB)。或者，基站120也可以是5G***中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本申请实 施例对基站120的具体实现方式不加以限定。
基站120和终端110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于***移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信***还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信***中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本申请实施例不做限定。
如图2所示，本实施例提供一种信息指示方法，包括：
根据TB的重复传输次数，与MCS之间的映射关系，下发联合指示信息，其中，联合指示信息，用于通过指示映射关系，指示所调度的TB的重复传输次数并同时指示MCS。
本实施例提供的信息指示方法可应用于基站中。这里的TB是一种内 容块；不同的TB包含的数据内容不同。此处的TB可为MTC技术中所提出的传输块。MTC终端利用TB进行数据传输之前，可利用MTC物理下行控制信道(MTC Physical Downlink Control Channel，MPDCCH)进行TB传输的调度，例如，利用MPDCCH下发的下行控制信息(Downlink Control Information，DCI)指示TB、TB数量及一个TB的重复传输次数等信息。
在本实施例中，重复传输次数可任意正整数，通过重复传输次数的配置，则一个TB被重复传输次数就确定了，通过重复传输可以确保了传输的可靠性。如此，在一次传输未成功的时候，可以通过重复传输的TB接收成功；再例如，在一次传输未完全成功接收对应的TB时，可以通过重复传输的多次接收，联合解码，从而确保TB的传输成功率。
基站预先配置好TB的重复传输次数，与MCS之间的映射关系；或者，在通信协议中预先规定好TB的重复传输次数，与MCS之间的映射关系。
这种映射关系，还可以由基站实现发送给终端。
在一些实施例中，TB的重复传输次数和MCS是利用不同的信息域进行指示，而每一种的信息域所占用的比特数又与TB的重复传输次数的备选个数和MCS的备选个数相关。例如，利用M1比特指示重复传输次数，利用M2比特指示MCS，如此一共至少得消耗M1+M2比特。而在本实施例中，联合指示信息指示的是TB的重复传输次数与MCS之间的映射关系，例如，可以用N(N小于M1+M2)个比特就指示完所有的映射关系，而终端接收到该N比特的联合指示信息之后，同时能够确定出基站指示的重复传输次数和MCS，从而减少了信令开销。
表1为一种联合指示信息、重复传输次数重复传输次数及MCS之间的映射关系表：

11100 14 R3
11101 14 R4
11110 15 R3
11111 15 R4
表1
表1中重复传输次数R1、R2、R3及R4可以为任意正整数。
在一些实施例中，R1、R2、R3及R4依次增大。
若采用表1中重复传输次数与MCS之间的映射关系，如此，仅需要5个比特就能够同时完成重复传输次数重复传输次数和MCS等级的指示。
本实施例中TB可为分配给MTC终端的TB。在本实施例中，考虑由于MTC终端大多数处在室内等网络覆盖条件不太好的地方，同时由于MTC终端相比于非MTC终端(例如，手机终端等)，为处理能力相对较弱的设备。因此需要对MTC终端进行覆盖增强，例如，在多个传输时间单元中重复传输相同的内容，接收端(例如，MTC终端)联合所重复传输的内容进行信息的恢复。重复传输次数一般根据信道条件进行设置。信道条件越差，则重复传输次数越大。
具体来说，MTC有两种覆盖增强模式，覆盖增强模式A和覆盖增强模式B。
覆盖增强模式A应用于信道条件较好的情况下，因此在覆盖增强模式A下可支持的重复传输次数相对较小。
覆盖增强模式B通常应用于信道条件较差的情况，因此可支持的重复传输次数较大。
在两种覆盖增加模式下，基站首先会通过高层信令(例如，RRC信 令)为终端配置多个可选的重复传输次数，比如配置4个可选的重复传输次数。基站会根据用户当前的信道情况和MCS选择在多个备选的重复传输次数中设置一个合适的重复传输次数，并在DCI中进行指示。此处的高层信令可为物理层以上的信令，例如，例如，通过媒体访问控制(MAC)层信令或者无线资源控制(RRC)信令层信令。
MTC终端支持不同调制解调方案以应对不同的信道场景。比如在MTC覆盖增强模式A下，就支持16中MCS。16种MCS在不同的资源分配中可以承载不同数量的比特。
在表2中，I MCS为MCS等级的编号，I TBS为对应的TBS的编号。N PRB为分配给用户的物理资源的数量。表2中的数字表示在不同的调制编码方式和不同的资源配置下传输的数据块所承载的信息bit。比如当I MCS为9，N PRB为6，对应的数据块的大小为936。
Figure PCTCN2019096441-appb-000001
表2
表2中传输块集合(Transmission Block Set，TBS)指的是PRB分配和MCS等级的组合。
MTC终端的一个MPDCCH消息可用于调度一个MTC终端物理下行共享信道(MPDSCH)或者物理上行共享信道(PUSCH)。MTC终端在接收或者发送数据前都需去接收和盲检MPDCCH。当MTC终端发送或者一个数据量较大的数据包，需要经过几轮调度才能完成。
而在大多数情况下，由于信道状况相似，几次MPDCCH的调度内容都类似。即使在这种情况下，终端仍然需要解调每次调度的MPDCCH，消耗功率。为了减少的功率消耗，本申请实施例中MTC终端的图3所示的MPDCCH调度方法。
在图3中，一个时刻的MPDCCH消息调度了4个时刻的MPDSCH的传输。图3中4个MPDSCH分别是MPDSCH1、MPDSCH2、MPDSCH3及MPDSCH4。
本实施例中联合指示信息可为携带在MPDCCH消息中的信息。MPDCCH消息为利用MPDCCH发送的消息。在MTC覆盖增强模式A下，MPDCCH一个下发的DCI最多可以调度8个下行接收的TB。在覆盖增强模式B下，一个MPDCCH下发的DCI最多可以调度4个下行接收的TB。本实施例提供基站下发的联合指示信息可为在MTC终端处于增强覆盖模式A或者增强覆盖模式B下时发送的DCI。
在一些实施例中，TB的重复传输次数，与MCS之间的映射关系，包括：
TB的重复传输次数，与不同的MCS等级之间的映射关系。
如表1可知，重复传输次数R1、R2、R3及R4都对应了不同的MCS等级；而不同的映射关系所对应的5个比特的比特值不同，如此，终端接收到基站下发的5个比特的联合指示信息，就能够明确的知道当前基 站指示的重复传输次数和MCS等级。
不同的MCS等级的增强覆盖效果不同，如此，在本实施例中，在建立MCS等级与重复传输次数的映射关系时，将平衡考虑增强覆盖效果和重复传输次数，确保MTC终端等接收端的接收成功率。
在一些实施例中，TB的重复传输次数，与不同的MCS等级之间的映射关系，包括：
第一次数集合，与高于第一门限的MCS等级之间的映射关系，其中，第一次数集合包括：一个或多个重复传输次数；
和/或，
第二次数集合，与等于或低于第一门限的MCS等级之间的映射关系，其中，第二次数集合包括：一个或多个重复传输次数；
其中，第二次数集合与第一次数集合所包含重复传输次数的个数不同，和/或，所包含重复传输次数至少一个不同。
例如，MTC终端支持的MCS等级共16种，分别是0到15。此处的第一门限为MCS等级的等级门限。
在本实施例中，第一次数集合和第二次数集合包含至少一个重复传输次数。第一次数集合和第二次数集合包含的重复传输次数的个数不同，或者，个数相同但是重复传输次数的取值不同。
在本实施例中，将终端支持的MCS等级基于第一门限至少范围为两个子范围，分别为这两个子范围设置了第一次数集合和第二次数集合。如此，联合指示信息通过指示映射关系，可以简便的告诉终端当前基站指示的TB的重复传输次数和允许终端使用的MCS等级。
在一些实施例中，根据传输块TB的重复传输次数，与调制编码策略MCS之间的映射关系，下发联合指示信息，包括：
根据TB的重复传输次数，与MCS及TB数量之间的映射关系，下 发联合指示信息，其中，联合指示信息，还用于通过指示映射关系，指示TB数量。
在本实施例中，映射关系进一步的是重复传输次数、MCS及TB数量三者之间的映射关系。
TB数量为不同TB的数量，即传输不同内容的TB的数量。TB的数量与终端所需传输的数据量相关。
表3为本申请实施例提供的一种TB的重复传输次数、MCS及TB数量之间的映射关系。
Figure PCTCN2019096441-appb-000002
Figure PCTCN2019096441-appb-000003
表3
在本实施例中可以由一个信息域完全承载的联合指示信息，同时指示的重复传输次数、TB数量及MCS等级，再次节省了信令开销。
例如，按照表3限定了重复传输次数、MCS及TB数量之间的映射关系，可以仅使用6个比特就完成指示。
在一些实施例中，如图4所示，本申请实施例提供的方法具体可为：
根据TB的重复传输次数，与MCS及TB数量之间的映射关，下发联合指示信息。
TB的重复传输次数，与MCS及TB数量之间的映射关系，包括：
第三次数集合，与第一TB数量及第一MCS集合之间的映射关系，其中，第三次数集合包含至少一个重复传输次数；第一MCS集合包含至少一个MCS等级；
和/或，
第四次数集合，与第二TB数量及第二MCS集合之间的映射关系，
其中，第四次数集合包含至少一个重复传输次数；第二MCS集合包含至少一个MCS等级。
参见表3可知，若第一TB数量为1，MCS等级可为0至15，即第一MCS集合可包括编号为0至15的MCS等级。与此同时，对应的重复传输次数可以在R1至R4中，基于第一TB数量及MCS等级进行变动。
再例如，若第二数量为2，则MCS等级可为9至15，即第二MCS集合可包括编号为9至15的MCS等级。与此同时，对应的重复传输次数可以在R3至R4中，基于第二TB数量及MCS等级进行变动。
再例如，第一TB数量为3，MCS等级可为11和13，即第一MCS集合可包括编号为0和13的MCS等级。与此同时，对应的重复传输次数可以在R3至R4中，基于第一TB数量及MCS等级进行变动。
在一些实施例中，第二TB数量大于第一TB数量；
第二MCS集合包含的MCS等级数量，多于第一MCS集合包含的数据；
第三次数集合所包含重复传输次数的数量，多于第四次数集合所包含重复传输次数的数量；和/或，第三次数集合所包含重复传输次数的均值，小于第四次数集合所包含重复传输次数的均值。
采用这种设置方式，可以很好平衡重复传输次数、允许终端使用的MCS等级及TB数量对终端的接收效果，同时利用联合指示信息通过映射关系的指示，一次性告知终端重复传输次数，与MCS等级和TB数量中的一个或两个。
在一些实施例中，映射关系可为：预先写入到通信协议中的映射关系，如此，终端出厂或者基站建立时，就写入了映射关系。
在一些实施例中，映射关系可为预先协商的映射关系，例如，基站在广播消息或者组播消息中下发的映射关系。总之，基站和终端都预先知道前述任意一种映射关系，基站在下发联合指示信息时，根据重复传输次数的需求，查询映射关系，下发联合指示信息。
如图5所示，本实施例提供一种信息确定方法，其中，包括：
步骤S210：接收联合指示信息；
步骤S220：根据联合指示信息所指示的映射关系，确定TB的重复传输次数，并确定MCS。
本实施例中该信息确定方法应用于终端中，例如，前述MTC终端中。终端接收的是联合指示信息，而非单独指示一个信息内容的单独指示信 息。
接收到联合指示信息之后，需要根据联合指示信息所对应的映射关系，在知道重复传输次数的同时，还会知道MCS。
如此，终端通过一个联合指示信息的接收，同时知道了重复传输次数和MCS，减少了接收的信令开销。
在一些实施例中，方法还包括：
根据联合指示信息所指示的映射关系，确定TB数量。
本实施例中，映射关系可能为重复传输次数和MCS两者之间的映射关系，还可能为重复传输次数、MCS及TB数量三者之间的映射关系。若映射关系为三者之间的映射关系，则终端还会根据联合指示信息，确定TB数量。
在本实施例中，不管是重复传输次数与MCS两者之间的映射关系，还是重复传输次数、MCS及TB数量三者之间的映射关系，都可以参见前述实施例，此处就不再重复了。
如图6所示，本实施例提供一种信息指示装置，包括：
下发模块，被配置为根据传输块TB的重复传输次数，与调制编码策略MCS之间的映射关系，下发联合指示信息，其中，联合指示信息，用于通过指示映射关系，指示所调度的TB的重复传输次数并同时指示MCS。
本实施例提供的下发模块可为程序模块，该程序模块被处理器执行后，能够实现联合指示信息的下发。
在一些实施例中，装置还可包括：存储模块；存储模块可以用于存储映射关系和/或联合指示信息。

以下结合上述任意实施例提供几个示例：
示例1：
利用多TB调度的特点和各个信息域之间的关系对信息域进行压缩，同时进行联合编码以达到降低信令开销的目的。
利用不同信息域之间的关系，对信息域进行压缩，同时进行联合编码。MCS选择和重复传输次数的设置都是基于信道条件进行设置的。
在相同的信道条件下，可以设置较高等级的MCS，那么此时重复传输次数就会增多。
另外一种情况是设置较低等级的MCS，那么此时重复传输次数相对就会变少。
利用这种效益，可以对MCS和重复传输次数进行联合编码，得到前述联合编码信息。
在多TB调度的情况下，通常数据包的数据量比较大。为了减少传输的次数，在调度的TB数比较大的情况下，限制传输数据块的数据量，比如只允许传输大的数据块。那么此时就需要选择较大的MCS，利用这个效益，可以对调度的TB数和MCS进行联合编码。同时还可以对MCS，重复传输次数和调度的TB数三者进行联合编码。
示例2：
假设基站给用户配置的可选重复传输次数为{R1，R2，R3，R4}。在选择特定等级的MCS时，限制可选的重复传输次数，比如当MCS等级小于门限X1，则可选的重复传输次数只有{R1，R2}，当MCS等级大于门限时，则可选的重复传输次数为{R3，R4}。
将MCS与其对应的可选的重复传输次数进行联合编码，生成了如表1所示的联合指示信息、MCS及重复传输次数之间的映射关系。
示例3：
调度TB数与MCS间的压缩和联合编码，得到前述联合指示信息。 当所调度的TB数目小于门限Y1，可以使用更多的MCS等级，当所调度的TB数目大于此门限时，则限制使用MCS等级的数量。
上述决定的TB数门限可以有一个，也可以有多个。上述门限可以是协议固定，也可以有高层信令进行配置。
例如，当所调度的TB数为1时，此时可以使用所有的MCS等级，当所调度的TB数为2时，此时只可以使用其中的四种MCS等级，当所调度的TB数大于2时，此时使用其中的两种MCS等级。
表4为本示例提供的一种联合指示信息、TB数量及MCS等级之间的映射关系。

示例4：
调度TB，MCS和重复传输次数之间的压缩和联合编码
此方法为方法一和方法二的合并，即在不同的TB数下限制MCS等级，在特定的MCS下限制重复传输次数，并对TB数，MCS等级和重复传输次数进行联合编码。总之在本申请实施例中，在不同的MCS下对可选的重复传输次数进行限制，并进行联合编码得到联合指示信息。在不同的调度TB数下对MCS选择进行限制，并进行联合编码。本示例提供的映射关系可如前述表3所示。
