具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
下面对本申请实施例涉及到的部分背景相关知识进行介绍。
随着通信技术的不断演进，物联网(Internet Of Things，IoT)技术也随之飞速发展，同时也随之出现了成本低、功耗小、覆盖场景深广的机器类型通信(Machine Type Communication，MTC)的终端设备。
现有的支持MTC的终端设备通常存在成本低、数据速率低、传输时延高的特点，为了满足部分相对较高速率的物联网场景，例如智能安防中的视频监控，传统技术通过减少新空口(New radio，NR)的终端设备中配备的射频通道数目，以降低NR的终端设备的成本，并将降低了成本的NR的终端设备做为MTC的终端设备，以适应相对较高速率的物联网场景。
NR的终端设备至少需要支持2个接收通道，某些频段上的NR终端需要支持4个接收通道。每一个接收通道均包含接收天线、滤波器、PA功率放大器、AD采样器等元器件，因此，减少NR的终端设备的射频通道数目可以显著降低终端成本。将两个射频通道缩减为一个射频通道，则该终端设备的成本可降低约1/3。虽然减少终端设备的射频通道数目虽然可以有效降低成本，但由于接收天线数目的减少，使得接收到的信号功率降低，影响接收性能，进而影响覆盖范围。例如，将终端设备的接收天线数目从2减少至1，接收的信号功率会损失3dB左右。
现阶段还存在NR-light的终端设备，例如智能可穿戴设备，受限于设备的体积，终端设备的射频天线尺寸受限，因此射频天线的增益达不到普通终端的射频天线增益的性能，由此在相同的发射功率的限制下，NR-light终端设备的覆盖范围较小。
某些场景下，如工业监测的场景，通信模块可能会置于有金属物体(如机械臂)遮挡的区域，因此，网络信号强度会有所损失，针对这类工作场景，也需要设计覆盖增强的方案弥补性能损失。
本申请提供的数据传输方法可以解决现有的终端设备的下行覆盖范围较小这一技术问题。需要说明的是，本申请的数据传输方法并不仅限于解决上述技术问题，还可以用以解决其它的技术问题，本申请中不加以限制。

下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
在一个实施例中，本实施例涉及的是通过重复发送待传输信号提高终端设备的覆盖范围的具体过程，该方法包括：采用目标重复传输次数，重复发送待传输信号。
其中，目标重复传输次数可以是预设在终端设备中的重复传输次数，例如，可以是根据终端设备的接收通道的增益，预设上述目标重复传输次数；也可以是根据指示目标重复传输次数的信息确定的重复传输次数，本申请实施例对此不做限限制。需要说明的是，用于指示目标重复传输次数的信息可以是网络设备发送给终端设备的，也可以是其他终端设备发送的，本申请实施例对此不做限制。在接收上述指示目标重复传输次数的信息时，可以通过接收无线资源控制(Radio Resource Control，RRC)信令接收，也可以通过接收控制信息接收，还可以通过接收媒质接入控制控制信元(Media Access Control Control element,MAC CE)接收，本申请实施例对此不做限制。
在需要重复发送待传输信号时，通过重复发送上述目标重复传输次数的待传输信号，增强待传输信号的增益，增大信号的覆盖范围。每多发送一次上述待传输信号，均可以将各次发送的待传输信号的增益进行合并，增强待传输信号的信号增益。例如，发送2次待传输信号，相当于将单次发送的信号的功率增大2倍，带来10log2＝3dB的信号增益；发送10次待传输信号，相当于将单次发送的信号的功率增大10倍，带来10log10＝10dB的信号增益。待传输信号的信号增益越大，终端设备的覆盖范围越广。也即是说，通过重复多次发送待传输信号，可以提高终端设备的覆盖范围。
上述信号传输方法，采用目标重复传输次数，通过重复多次传输待传输信号，使得减少射频通过数目的终端设备，可以通过多次重复传输合并待传输信号的增益，得到更大增益的待传输信号，进而使得终端设备的覆盖范围扩大。
随着终端设备位置或周围环境的变化，终端设备所需重复传输信号的次数也会随之变化，可以通过接收携带在实时发送的下行控制信息中的指示目标重复传输次数的信息，以快速的适应终端设备位置或周围环境的变化导致的重复传输次数的变化。下面通过图2来详细说明。
图2为一个实施例中信号传输方法的流程示意图，如图2所示，该方法包括以下步骤：
S101、接收携带重复传输信息的第一消息；重复传输信息用于指示终端设备上待传输信号的目标重复传输次数；第一消息包括下行控制信息(Downlink control information，DCI)。
其中，第一消息可以是下行控制信息，下行控制信息通常是在网络设备与终端设备之间进行控制信息交互时，由网络设备发送给终端设备的，终端设备根据该下行控制信息向网络设备发送上行控制信息。下行控制信息通常是通过物理层直接发送给终端设备的，与高层的信令相比，例如RRC信令，在发送下行控制信息时，不需要通过高层向低层逐层传递，也即是不需要逐层传递时对信令进行封包、拆包等处理，也即是说，下行控制信息较为简洁。另外，与高层的信令相比，下行控制信息不需要同时携带其他配置信息，可以单独携带指示目标重复传输次数的信息，也即是可以随时的调整其中携带的指示目标重复传输次数的信息，灵活性高。
在重复传输待传输信号时，存在一种可能的情况，用于重复传输待传输信号所使用的资源被配置为与待传输信号不匹配资源，例如，待传输信号为上行信号，终端设备基于时隙配置的配置信息，确定一个时隙上行信道中分配符号中包含下行传输符号，则终端设备在进行重复发送待传输信号时，只能使用该时隙中除上述下行传输符号之外的其他符号，因此存在一种可能的情况，该时隙中可用于进行重复传输的符号的数量小于重复发送待传输信号所需的符号数量，该时隙上行传输会被取消。可选地，目标重复传输次数为预设的重复传输次数加上预设数值，预设数值为根据时隙中各符号的传输属性确定的数值，传输属性用于指示待传输信号是否可以采用符号传输。其中，预设的重复传输次数可以是预先设置的固定的重复传输次数，例如，预设的重复传输次数可以是传统方法中通过RRC信令发送给终端设备的重复传输次数。传统方法中，当出现了进行重复传输的符号的数量小于重复发送所述待传输信号所需的符号数量的时隙时，该时隙不能传输待传输信号，通常仍会将该时隙计入重复传输次数中，导致实际进行重复传输的次数小于所需重复传输的次数。通过在实时性更高的下行控制信息中携带重复传输信息，其中所指示的目标重复传输次数为预设的重复传输次数加上预设数值，预设数值为根据时隙中各符号的传输属性确定的数值，传输属性用于指示待传输信号是否可以采用符号传输，这样可以有效的避免出现上述情况。例如，实际需要进行重复传输的次数为5次，将重复传输信息中指示的目标重复传输次数为8次，则即使存在个别的不能进行传输的时隙，总的重复传输次数仍能满足实际需求。
重复传输信息用于指示终端设备上待传输信号的目标重复传输次数，其可以是指示目标重复传输次数的数值，也可以是指示目标数值的标识信息，本申请实施例对此不做限制。
S102、根据重复传输信息，确定目标重复传输次数。
在从第一消息中获取了重复传输信息时，可以根据上述重复传输信息具体形式，确定该重复传输信息指示的目标重复传输次数。例如，当重复传输信息为指示重复传输次数的数值，则将该数值作为目标重复传输次数；当重复传输信息为指示目标数值的标识信息，可以根据该标识信息确定其所指示的目标数值，并将该目标数值作为目标重复传输次数。
上述信号传输方法，接收携带有指示待传输信号的目标重复传输次数的重复传输信息的第一消息，并根据重复传输信息，确定目标重复传输次数，其中，第一消息包括下行控制信息。当第一消息为下行控制信息时，与高层信令相比，通过下行控制信息携带重复传输信息，可以及时的根据终端设备位置或周围环境的变化，调整目标传输次数，使得重复传输信息中指示的目标重复传输次数，可以快速的适应由于终端设备位置或周围环境的变化导致的重复传输次数的变化，以使重复发送待传输信号中所采用的的目标重复传输次数，能够更及时的适应终端设备的位置或周围环境的变化。
在一个实施例中，上述重复传输信息包括待传输信号的目标重复传输次数，或，目标重复传输次数的标识。
当上述重复传输信息为目标重复传输次数的标识时，可选地，目标重复传输次数的标识为目标重复传输次数在重复传输次数集合中的目标序号；其中，重复传输次数集合为预设的次数集合，或者，根据预配置指令配置的次数集合。预设的次数集合可以是根据终端设备自身的性能确定的多个重复传输次数形成的集合。根据预配置指令配置的次数集合可以是根据接收到的配置指令中指示的重复传输次数确定的次数集合。可选地，上述重复传输次数集合包括至少一个候选序号，每个候选序号对应一个重复传输次数。例如，重复传输次数集合{8,10,12,18}包括4个候选序号，分别为1,2,3,4，其中候选序号1对应的重复传输次数为8，候选序号2对应的重复传输次数为10，候选序号3对应的重复传输次数为12，候选序号4对应的重复传输次数为18。
可选地，将目标序号对应的重复传输次数，确定为目标重复传输次数。
例如，重复传输信息中的目标重复传输次数的标识可以用2个比特表示，用于指示重复传输次数集合中的目标序号，如“00”表示重复传输次数集合中的候选序号1，“01”表示重复传输次数集合中的候选序号2，“10”表示重复传输次数集合中的候选序号3，“11”表示重复传输次数集合中的候选序号4。当接收到重复传输信息中目标重复传输次数的标识为01时，目标重复传输次数在重复传输次数集合中的目标序号为2，对应的目标重复传输次数为重复传输集合{8,10,12,18}的候选序号2对应的数值10。
上述实施例重点描述了如何根据接收的第一消息确定目标重复传输次数的具体过程，下面通过以下实施例来详细描述如何确定重复发送待重复信号所使用的上行资源。
在一个实施例中，每次重复发送待传输信号所使用的上行资源相同，或，每次重复发送待传输信号所使用的上行资源不同。
每次重复发送待传输信号所使用的上行资源可以是指发送待传输信号所占用的符号资源，每次重复发送待传输信号所使用的上行资源可以相同，也可以不同。可选地，待传输信号包括上行控制信号和探测参考信号(sounding reference signal，SRS)。
例如，通过5个时隙重复5次发送待传输信号，5次重复发送待传输信号所占用的符号资源相同，均为每个时隙中的前5个符号资源。当然5次重复发送待传输信号所占用的符号资源也可以不同，例如，在第一个时隙发送待传输资源可以是第一个时隙中的第0-4的符号，在第二个时隙发送待传输资源可以是第二个时隙中的第1-5的符号，在第三个时隙发送待传输资源可以是第三个时隙中的第2-6的符号，在第四个时隙发送待传输资源可以是第四个时隙中的第3-7的符号，在第五个时隙发送待传输资源可以是第五个时隙中的第4-8的符号。还存在一种情况，即重复发送待传输信号时，部分时隙所占用上行资源的相同。例如，5次重复发送待传输信号，其中在第一个时隙、第三个时隙和第五个时隙占用的符号相同，为第1-5的符号，在第二个时隙和第四个时隙占用的符号相同，为第3-7的符号。
终端设备可以根据接收到携带资源配置信息的第二消息确定待传输信号所使用的上行资源。在一个实施例中，该方法还包括：
S201、接收携带资源配置信息的第二消息；资源配置信息用于指示重复传输待传输信号时所使用的上行资源；第二消息包括无线资源控制信令、下行控制信息或MAC CE。
其中，资源配置信息用于指示重复传输待传输信号时所使用的上行资源，资源配置信息可以是直接指示重复传输待传输信号时所使用的符号；也可以是通过发送配置参数，以使终端设备根据配置参数及对应的计算方法，确定重复传输待传输信号时所使用的符号；本申请实施例对此不做限制。上述资源配置信息可以携带在第二消息中，当终端设备接收到第二消息时，可以从第二消息中获取资源配置信息，进而根据资源配置信息确定重复传输待传输信号时所使用的上行资源。第二消息可以包括无线资源控制信令、下行控制信息或MAC CE。也即是说，终端设备可以在接收RRC信令或MAC CE时接收资源配置信息，也可以在接收DCI时接收发送给终端设备的资源配置信息，本申请实施例对此不做限制。
S202、采用目标重复传输次数，在资源配置信息所指示的上行资源上，重复发送待传输信号。
上述信号传输方法，终端设备可以通过接收携带指示重复传输待传输信号时所使用的上行资源的资源配置信息的无线资源控制信令、下行控制信息或MAC CE，采用目标重复传输次数，在资源配置信息所指示的上行资源上，重复发送待传输信号，也即是说终端设备可以通过多种类型的消息接收资源配置信息，提高了获取资源配置信息的灵活性。
在一个实施例中，还可以通过携带重复传输信息的第一消息中携带资源配置信息，以使终端设备在接收到的第一消息时，可以同时获取重复传输信息和资源配置信息。如图4所示，该方法还包括以下步骤：
S301、第一消息中还携带资源配置信息，资源配置信息用于指示重复传输待传输信号时所使用的上行资源。
其中，第一消息中携带有重复传输信息和资源配置信息，且第一消息可以是实时性更高的下行控制信息。终端设备在接收到第一消息时，可以根据第一消息中携带的重复传输信息确定待传输信号的目标重复传输次数，同时根据资源配置信息确定重复传输待传输信号是所使用的上行资源。
S302、采用目标重复传输次数，在资源配置信息所指示的上行资源上，重复发送待传输信号。
上述信号传输方法，第一消息中还携带用于指示重复传输待传输信号时所使用的上行资源，终端设备可以在接收到第一消息时获取资源配置信息，其中，第一消息可以是实时性更高的下行控制信息，使得终端设备重复发送待传输信号时，所使用的上行资源可以根据终端设备的变化及时调整，提高了重复发送待传输信号的上行资源利用率。
在一个实施例中，上述资源配置信息为资源配置参数，或资源配置参数集合，其中，资源配置参数用于使终端设备确定每次重复传输待传输信息时所使用的上行资源；资源配置参数集合中包括：至少一个资源配置参数，和各资源配置参数与传输次数的对应关系。
可选地，若资源配置信息为资源配置参数，则根据资源配置参数确定每次重复传输待传输信号所使用的上行资源。终端设备可以根据资源配置参数，为每次重复传输待传输信号确定相同的上行资源。可选地，资源配置参数包括资源块的偏置量和/或上行资源索引号。资源配置参数可以是资源块的偏置量
Figure PCTCN2020075770-appb-000001
也可以是上行资源索引号r PUCCH，还可以是
Figure PCTCN2020075770-appb-000002
和r PUCCH。在一种可能的情况下，资源配置参数为第i个时隙的资源块偏置量，可以根据公式

可选地，若资源配置信息为资源配置参数集合，可以通过图5所示的方法步骤确定每次传输待传输信号所使用的上行资源。如图5所示，包括：
S401、根据资源配置参数集合确定每次重复传输待传输信号对应的资源配置参数。
S402、根据对应的资源配置参数，确定每次重复传输待传输信号所使用的上行资源。
由上述实施例的描述可知，资源配置参数集合中包括至少一个资源配置参数，和各资源配置参数与传输次数的对应关系。其可以是多次传输对应一个资源配置参数，也可以是一次传输对应一个资源配置参数，本申请实施例对此不做限制。例如，当待传输信号的目标重复传输次数为5次时，资源配置参数集合中包括3个资源配置参数，其中，第一次重复传输和第二次重复传输对应第一个资源配置参数，第三次重复传输和第四次重复传输对应第二个资源配置参数，第五次重复传输对应第三个资源配置参数。也即是说，采用第一个资源配置参数确定第一次和第二次重复传输待传输信号所使用的上行资源，采用第二个资源配置参数确定第三次和第四次重复传输待传输信号所使用的上行资源，采用第三个资源配置参数确定第五次重复传输待传输信号所使用的上行资源。
上述信号传输方法中资源配置信息只包括用于指示次传输待传输信号所使用的上行资源的资源配置参数，或，资源配置参数集合。在一种可能的情况下，资源配置信息中还包括有重传资源异同指示，重传资源异同指示表征每次重复传输待传输信号时所使用的上行资源的配置是否相同。
在一个实施例中，上述资源配置信息包括：重传资源异同指示，和/或资源配置参数；重传资源异同指示用于指示每次重复传输待传输信号时所使用的上行资源的配置是否相同；资源配置参数用于使终端设备确定每次重复传输待传输信息时所使用的上行资源。
可选地，若资源配置信息为重传资源异同指示，或者，资源配置信息为重传资源异同指示和资源配置参数，则第二消息为下行控制信息。
当资源配置信息为重传资源异同指示，或者，资源配置信息为重传资源异同指示和资源配置参数，也即是说当资源配置信息中包括有重传资源异同指示时，资源配置信息携带在下行控制信息中。在一种情况下，当资源配置信息中不包括重传资源异同指示时，例如资源配置信息为资源配置参数时，资源配置信息可以携带在RRC信令、MAC CE或下行控制信息中。
可选地，若重传资源异同指示表征每次重复传输待传输信号时所使用的上行资源的配置不同时，资源配置参数包括每次传输待传输信号时的资源配置参数。

终端设备可以通过相同目标波束发送多个重复传输的待传输信号，通过多个重复发送的待传输信号的空间分集增益，提高待传输信号的信号功率。终端设备也可以通过不同的目标发射波束发送重复传输的待传输信号。例如，终端设备可以通过一个目标波束重复发送待传输信号，也可以是在需要重复发送5次待传输信号时，通过第一个目标波束发送第一次待传输信号，通过第二个目标波束发送第二次待传输信号，通过第三个目标波束发送第三次待传输信号，通过第四个目标波束发送第四次待传输信号，通过第五个目标波束发送第五次待传输信号。在一种可能的情况下，还可以通过第一个目标波束发送第1-3次重复发送的待传输信号，通过第二个目标波束发送第4-5次重复发送的待传输信号。
