Description

通信方法、装置及存储介质
本申请要求于2018年11月02日提交中国专利局、申请号为201811301903.8、申请名称为“通信方法、装置及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置及存储介质。
背景技术
低延时高可靠通信(ultra low latency and reliable communication，URLLC)和车到任何设备(vehicle to everything，V2X)应用场景要求支持数据高可靠的传输，而若要支持数据高可靠的传输，需要同时支持控制信息的高可靠传输和数据的高可靠传输。因而，如何在第五代(5th-Generation，5G)通信系统中实现低时延、高可靠的信息传输是亟待解决的问题。
要实现整个传输的高可靠性，需要同时支持控制信息的高可靠传输和数据的高可靠传输。例如，V2X要实现端到端传的可靠性方面，V2X要求达到99.999％，而URLLC则要求可靠性达到99.9999％.因此，如何高可靠的传输，是5G中的关键技术。
进一步地，在实现高可靠传输过程中，还需要控制接收机的实现复杂度，包括接收机的检测复杂度以及接收机的缓存大小。从而以合理的代价和成本来实现高可靠的传输。因此，如何实现端到端的高可靠传输的条件下，合理地控制对接收设备的检测复杂度、缓存的要求是一个需要解决的问题。

在本实施例中，第一设备使用控制信息对应的传输参数配置信息包括重传指示信息，利用该重传指示信息指示对应的控制信息是否为重传信息和/或指示对应的控制信息在N次传输中的第a次重传，这样第二设备在成功解调接收到的控制信息之前能够准确地确定出该控制信息是否为重传信息，且该控制信息在N次传输中第几次进行重传，使得第二设备可以有针对性的对接收到的控制信息进缓存和检测，降低了接收设备的缓存要求，提高 了接收设备的检测性能和检测成功率。
在一个可能的设计中，所述方法还包括：根据网络设备的配置指令或预配置的信息，确定该M个控制信息中用于指示数据信息所在的时域位置起点的控制信息。
在本实施例中，可以通过网络设备发送配置信令的形式提前指示或预配置信息的方式确定多个重传的控制信息中用于指示数据信息所在的时域位置起点的是哪一个控制信息，这样第二设备可以在不需要做盲检的情况下直接合并多个重传的控制信息，提高了检测效率。
在一个可能的设计中，所述获取M个控制信息中每个控制信息所对应的传输参数配置信息，包括：根据网络设备的配置指令或预配置的信息，获取所述M个控制信息中每个控制信息所对应的传输参数配置信息。

在另一个可能的设计中，所述M个控制信息中的至少一个控制信息所在的时域位置位于所关联的被调度的数据信息所在的时域位置之前。具体的：
所述M个控制信息所在的时域位置全部位于所关联的被调度的数据信息所在的时域位置之前；或者，

另一方面，本申请实施例提供一种通信方法，适用于第二设备，该方法包括：接收控制信息，该控制信息为M个控制信息中的一个，获取该述控制信息对应的传输参数，根据该控制信息对应的传输参数，确定该控制信息对应的重传指示信息，该M个控制信息中每个控制信息所对应的传输参数配置信息不同，每个传输参数配置信息包括：重传指示信息，所述重传指示信息用于指示对应的控制信息是否为重传信息和/或用于指示对应的控制信息在N次传输中的第a次重传，其中，M为正整数，N与a为整数。
在本实施例中，第二设备可以获取接收到的控制信息对应的传输参数，并根据该控制信息对应的传输参数，确定出该控制信息对应的重传指示信息，这样第二设备可以根据该重传指示信息对重传的控制信息进行合并或联合译码，以便确定出要缓存的数据信息，减少了盲检次数，降低了对第二设备的缓存要求，提高了第二设备的检测性能和检测成功率。
在一个可能的设计中，所述方法还包括：根据网络设备的配置指令或预配置的信息，确定所述M个控制信息中用于指示数据信息所在的时域位置起点的控制信息。
在一个可能的设计中，所述获取所述控制信息对应的传输参数，包括：根据网络设备的配置指令或预配置的信息，获取所述控制信息对应的传输参数。

在上述两个方面的一种可能的设计中，所述M个控制信息中的至少一个控制信息所在的时域位置位于所关联的被调度的数据信息所在的时域位置之前。
在本实施例中，控制M个控制信息中的至少一个控制信息所在的时域位置位于所关联的被调度的数据信息所在的时域位置之前，可以减少对数据信息的缓存，降低对第二设备的缓存能力要求。
示例性的，所述M个控制信息中的至少一个控制信息所在的时域位置位于所关联的被调度的数据信息所在的时域位置之前，具体为：
所述M个控制信息所在的时域位置全部位于所关联的被调度的数据信息所在的时域位置之前；或者，

在本实施例可以提高第二设备的检测效率，提高第二设备接收数据信息的可靠性，缩短第二设备获取到数据信息的时延。
在上述两个方面的一种可能的设计中，所述M个控制信息关联到同一个被调度的数据信息。
若第一设备发送的M个控制信息均是为了指示某个数据信息，那么该M个控制信息关联到同一个被调度的数据信息，表示该M个控制信息指示同一个数据，这样第二设备对接收到M个控制信息中的任意一个成功解调时，不需要再解调其他的控制信息，提高了第二设备的检测效率和检测成功率。
在上述两个方面的一种可能的设计中，所述M个控制信息中的内容相同。
在本实施例中，该M个控制信息中的内容相同，能够使得第二设备可以对接收到的多个控制信息进行联合译码，提高了检测效率。

示例性的，所述生成所述参考信号的序列的参数至少包括如下任意一种：序列初始值、根序列号、序列的循环移位值、序列跳或序列组跳。
在本实施例中，第二设备在接收到控制信息后，在解调控制信息之前通过对参考信号的参数进行估计就可以得到控制信息对应的重传指示信息，进而确定该控制信息是否为重 传信息和/或在整个传输中的第几次重传，从而可以在控制信息进行多次重传时，减少第二设备的缓存，提高控制信息的检测速度，减少处理时延。
在上述两个方面的一种可能的设计中，所述重传指示信息由用于承载对应控制信息的资源指示，所述资源至少包括如下的任意一种：控制信息对应的搜索空间参数或控制信息对应的控制资源集合。
示例性的，所述搜索空间参数至少包括如下任意一种：搜索空间的标识、搜索空间的周期和时隙位置、持续连续符号数、时隙中的时域符号数或汇聚级别。
示例性的，所述控制资源集合至少包括如下任意一种：控制资源集合的标识、控制资源集合对应的频域资源位置或控制资源集合占用的连续的时间长度。
在本实施例中，利用控制信息对应的搜索空间参数、控制资源集合分别或组合来指示控制信息的单次传输和重复传输以及当前的重复次数，可以减少第二设备的盲检测次数，降低检测复杂度。

低延时高可靠通信(ultra low latency and reliable communication，URLLC)和车到任何设备(vehicle to everything，V2X)应用场景均要求支持数据高可靠的传输。例如，在时延性方法，V2X要实现端到端传输时延不超过3ms的要求，URLLC要实现不超过10ms的端到端的时延要求。在可靠性方面，V2X要求达到99.999％，而URLLC则要求可靠性达到99.9999％.因此，如何在5G通信系统实现低时频、高可靠的传输是本申请实施例需要解决的技术问题。
示例性的，本实施例提供的通信方法可以用于蜂窝网络通信链路，也可以用于设备间通信链路，即设备到设备(device to device，D2D)通信链路。设备间链路有的地方又称之为边链路，侧行链路，副链路，其英文亦可以表示为sidelink。在本说明书中，为了描述的方便，将设备间链路统一称之为边链路。具体的，本申请的实施例主要适用于两个设备之间的通信过程，比如，网络设备与终端设备之间的通信过程、终端设备与终端设备之间的通信过程。
示例性的，本实施例的运用场景可以是蜂窝通信链路的上行和下行传输，该蜂窝网络例如包括一个网络设备(例如基站)和第一终端设备(UE1)、第二终端设备(UE2)。因而，该蜂窝通信链路的上行传输是指UE1和/或UE2到基站的传输，该蜂窝通信链路的下行传输是指基站到UE1和/或基站到UE2的传输。其中，该网络设备还可以是蜂窝网络中中继站等或其他类型的网络设备。

本申请为了解决现有技术中存在的对接收设备的缓存要求高、且接收设备检测性能和检测成功率低的问题，提出了一种通信方法，利用控制信息对应的传输参数配置信息的某个参数作为重传指示信息，接收设备在成功解调某个控制信息之前能够准确地确定出该控制信息是否为重传信息，且为重传信息时其在整个传输过程中的第几次重传。从而接收设备可以有针对性的对接收到的控制信息进缓存和检测，以降低接收设备的缓存要求，提高接收设备的检测性能和检测成功率。
下面，通过具体实施例对本申请的技术方案进行详细说明。需要说明的是，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。
图2为本申请实施例提供的通信方法实施例一的交互示意图。本实施例以通信系统中的第一设备和第二设备之间的信息交互进行说明。如图2所示，在本实施例中，该通信方法可以包括如下步骤：
步骤21：第一设备获取M个控制信息中每个控制信息所对应的传输参数配置信息。
其中，这M个控制信息中每个控制信息对应的传输参数配置信息不同，其中，每个传输参数配置信息包括：重传指示信息，该重传指示信息用于指示对应的控制信息是否为重传信息和/或用于指示对应的控制信息在N次传输中的第a次重传，其中，M为正整数，N与a为整数。
具体的，重传指示信息可以用于指示对应的控制信息是否为重传信息，重传指示信息也可以用于指示对应的控制信息在N次传输中的第a次重传，重传指示还可以用于指示对应的控制信息为重传信息，且该控制信息在N次传输中的第a次重传。
在本实施例中，N为通过指令指示的或预配置的某个控制信息在一个传输过程中的最大传输次数，即N为大于或等于1的整数。
a为某个控制信息在总的N次传输中属于第几次重传。a可以取0,1，…，N-1中的任意值，若a＝0，该控制信息为初次传输，若a＝1，该控制信息属于第1次重传。
可以理解的是，每个控制信息所对应的传输参数不同，只要两个控制信息所对应的两个传输参数中存在一个信息不同即表示这两个控制信息所对应的传输参数不同。例如，每个传输参数配置信息中所包括的重传指示信息可以为比特数1，用于表示重传，重传指示信息也可以为比特数0，表示非重传，和/或指示对应的控制信息在N次传输中第a次进行重传。
在本实施例中，M个控制信息中每个控制信息所对应的传输参数配置信息不同可以包括以下情形：
情形1：控制信息不做重传的情况，例如，M＝1，或者M>1且M个控制信息的内容不同，此时，M个控制信息中每个控制信息所对应的传输参数配置信息中的重传指示信息指示对应的控制信息为非重传信息，且在对应的N次传输中始终为第1次传输。
情形2：控制信息做重传的情况，M>1，且M个控制信息相同，此时，M个控制信息中每个控制信息对应的传输参数配置信息中的重传指示信息指示对应的控制信息为重传信息。例如M＝2，其中，对于M个控制信息中的第一个控制信息，其对应的传输参数配置信息中的重传指示信息指示该控制信息为非重传信息(初传信息)，其在对应的N次传输中为第1次传输，属于N次传输中为第0次重传；对于M个控制信息中的第二个控制信息，其对应的传输参数配置信息中的重传指示信息指示该控制信息为重传信息，其在对应的N次传输中为第2次传输，属于N次传输中为第1次重传。
上述用于指示控制信息是否为重传信息的重传指示信息其所属的传输参数配置信息和用于指示对应的控制信息在N次传输中的第a次重传的重传指示信息其所属的传输参数配置信息是不同的，因而，M个控制信息中每个控制信息所对应的传输参数配置信息是不同的。
在本实施例中，只要两个控制信息所对应的两个传输参数中存在一个信息不同即表示这两个控制信息所对应的传输参数不同，具体可以解释如下：
例如，两个控制信息所对应的两个传输参数均包括：参考信号映射到的频率位置、生成参考信号的序列的参数、用于承载对应控制信息的资源等3个信息，当用于承载这两个控制信息中每个控制信息的参考信号映射到的频率位置、生成每个参考信号的序列的参数、用于承载对应控制信息的资源中有一个信息不同或两个信息不同或三个信息均不相同，则表示这两个控制信息所对应的传输参数不同。
在本实施例中，重传指示信息可以用于只指示对应的控制信息在N次传输中的第a次重传，具体为：
当该重传指示信息承载在用于解调对应控制信息的参考信号中时，可以利用生成该参考信号的序列的参数来指示对应的控制信息在N次传输中的第a次重传。例如，将对应的控制信息在N次传输中的第a次重传的重传次数a作为生成参考信号使用的序列初始值。例如，当利用控制信息对应的搜索空间参数指示在N次传输中的第a次重传时，可以使用一个控制信息搜索空间周期中的不同时隙或同一个时隙中的不同符号来表示重传次数a。
在一种实施方式中，M＝N，且N>1时，例如N＝2，重传指示信息可以用于指示重传，此时，该重传指示信息可以指示对应的控制信息在N次传输中属于第0次或第1次重传。
示例性的，本实施例中的M和N可以是网络设备通过配置指令指示的，也可以是通过预配置的信息获取到的，也即，M和N可以是通过信令指示的，还可以是协议规定的，对此本申请实施例不做具体限定。
示例性的，在第一设备在通信过程中，可以根据第二设备对控制信息和/或数据的接收、解调情况来确定M个控制信息。例如，第二设备可以根据第一设备的反馈信息确定对控制信息和/或数据的接收、解调情况。又例如，第二设备可以根据第一设备对信道质量的预测结果确定对控制信息和/或数据的接收、解调情况。
在另一种示例中，M>N时，例如M＝4，N＝2，重传指示信息可以用于指示重传，这样，第一设备发送的M个控制信息中至少有一个控制信息是另一个控制信息的重传信息，因而， 该重传指示信息可以指示对应的控制信息在N次传输中属于第0次或第1次重传。
可选地，当M>N时，对于第二设备而言，只需要明确接收N次传输的控制信息即可。第二设备可以接收第一设备发送的M个控制信息中的任意位置的N次传输。例如，在一种情况下，第二设备可以接收M个控制信息中的第1次、第2次传输，在另一种情况下，第二设备可以接收M个控制信息中的第2次、第3次传输，在又一种情况下，第二设备还可以接收M个控制信息中的第3次、第4次传输。
在另一种示例中，M<N时，例如M＝1，N＝4，重传指示信息可以用于指示重传，该重传指示信息可以指示对应的控制信息在N传输中属于第0次或第1次或第2次或第3次重传。又如，M＝2，N＝4，重传指示信息可以用于指示所对应的控制信息属于N次传输中的任意连续或不连续的2次中的一个控制信息。
例如，假设某个控制信息的最大传输次数N为4次，且第一设备对该控制信息一共传输了4次，假设这4个控制信息的重传的编号值分别为0，1，2，3，这4个编号值可以承载在4个控制信息中每个控制信息所对应的传输参数配置信息中的不同参数的不同位置，这时重传指示信息指示对应的控制信息可以是这4次传输中的任意一次传输的控制信息，即a可以是0、1、2、3中的任意一个。
示例性的，每个控制信息对应的传输参数配置信息可以指示第一设备和第二设备通信时占用和/或使用的时频资源和/或参考信号。例如，第一设备需要向第二设备发送至少两个控制信息之前，第一设备需要获取该至少两个控制信息对应的传输参数配置信息。
在本实施例中，步骤21中第一设备获取M个控制信息中每个控制信息所对应的传输参数配置信息可以通过方式实现：
作为一个示例，第一设备可以根据网络设备的配置指令获取M个控制信息对应的传输参数配置信息，其中，所述配置指令可以为下行控制信息(downlink control information，DCI)、系统信息块(system information block，SIB)消息或者无线资源控制(radio resource control，RRC)消息。
本实施例中，利用网络设备通过配置指令指示重传指示信息的方式，即使用于作为重传指示信息的参数发生变化，网络设备可以将相应的变化通知通信过程中的设备，提高了接收设备确定重传指示信息的准确度。
作为另一个示例，第一设备可以根据预配置的信息，获取M个控制信息对应的传输参数配置信息。
即，传输参数配置信息可以是网络设备配置给第一设备的，或者也可以是第一设备通过预配置的信息获取的。
示例性的，在本申请的实施例中，第一设备和第二设备通信之前，第一设备和第二设备可以预配置重传指示信息，通过该重传指示信息用于指示对应控制信息是否为重传信息和/或用于指示对应的控制信息在N次传输中的第a次重传，这样第一设备在发送控制信息时，可以利用预配置的重传指示信息指示对应的控制信息是否为重传信息和/或用于指示对应的控制信息在N次传输中的第a次重传，相应的，第二设备在接收到控制信息时，可以首先根据与第一设备预设规定的内容，获取用于指示对应控制信息是否为重传信息和/或用于指示对应的控制信息在N次传输中的第a次重传的重传指示信息。
值得说明的是，本申请实施例中的预配置的信息可以是第一设备和第二设备在出厂前 预定好的，也可以是协议规定的，并分别写入第一设备和第二设备中的。对于预配置的信息，第一设备和第二设备可以直接从设备本身存储的内容中获取，不需要两者交互便能得到，简化了获取流程，效率高。关于预配置的具体含义此处不再赘述。
进一步地，控制信息所调度的数据可以是下行数据，也可以是上行数据，还可以是sidelink上的数据。
进一步地，在本实施例的另一实现方式中，第一设备还可以使用不同的无线网络临时标识(radio network tempory identity，RNTI)来区分控制信息是单次传输还是属于重传的多次传输。本申请实施例并不对其进行限定。可选地，区分的方式可以是对下行控制信令或边链路控制信令的循环冗余校验(cyclic redundancy check，CRC)进行加扰的方式实现。
步骤22：第一设备根据M个控制信息中每个控制信息所对应的传输参数配置信息，发送该M个控制信息。
在本实施例中，第一设备获取到M个控制信息对应的传输参数配置信息之后，可以根据该传输参数配置信息确定出控制信息传输所需要的时频资源的配置信息和/或参考信号的配置信息，进而可以在确定的时频资源上利用对应的参考信号发送该M个控制信息。
示例性的，在本实施例中，该通信方法在步骤22之前，第一设备根据该M个控制信息中每个控制信息所对应的传输参数配置信息，确定用于承载该M个控制信息中每个控制信息的时频资源。具体的，每个控制信息对应的传输参数配置信息可以包括时频资源的配置信息，例如，时频资源标识、时隙索引和/或OFDM符号索引等，因此，根据每个控制信息对应的时频资源的配置信息可以确定出用于承载每个控制信息的时频资源。
相应的，第一设备可以在根据该M个控制信息中每个控制信息所对应的传输参数配置信息确定的用于承载该M个控制信息中每个控制信息的时频资源上，发送该M个控制信息。
步骤23：第二设备接收控制信息，该控制信息为M个控制信息中的一个。
其中，该个数M可以是第一设备和第二设备可以根据预配置信息来确定的，或者是在网络设备的配置指令中指示的，或者是第一设备和第二设备根据协议预定义好的。
在本实施例中，当第二设备确定出控制信息对应的传输参数配置信息时，第二设备可以根据该传输参数配置信息确定出第一设备会在哪个时频资源上或者利用哪个参考信号发送控制信息，因而，第二设备可以接收控制信息。
示例性的，在本实施例中，该通信方法在步骤23之前，还可以包括第二设备根据控制信息对应的传输参数配置信息，确定用于承载控制信息的时频资源。
在本实施例中，由上述步骤21、22可知，控制信息对应的传输参数配置信息是通过网络设备的配置指令或者预配置的信息指示的，因此，第二设备可以根据网络设备的配置指令或者与配置的信息确定出控制信息对应的传输参数配置信息，进而根据传输参数配置信息中的内容确定出用于承载该控制信息的时频资源。
相应的，上述步骤23具体可以通过如下方式实现：第二设备在根据该控制信息对应的传输参数确定的用于承载该控制信息的时频资源上，接收该控制信息。
步骤24：第二设备获取上述控制信息对应的传输参数。
在本实施例中，第一设备会向第二设备发送M个控制信息，但是并不能保证所有的控制信息均能发送成功，第二设备也只能一个一个的接收上述控制信息，且不能事先获知会 接收到几个，以及接收到的某个控制信息是上述第一设备发送的M个控制信息中的哪一个，所以，第一设备和第二设备在通信时，通过使每个控制信息对应一个传输参数，利用控制信息对应的传输参数来指示其属于上述M个控制信息中的哪一个。
示例性的，本实施例中，第二设备在接收到控制信息之后，通过查询自身存储的与控制信息有对应关系的相关内容，可以容易获知上述控制信息对应的传输参数。值得说明的是，第二设备自身存储的与控制信息有对应关系的相关内容是根据网络设备的配置指令或者预配置的信息中获知并存储的。
因而，在本实施例中，该步骤24可以通过如下方式实现：第二设备根据网络设备的配置指令或预配置的信息，获取该控制信息对应的传输参数。
也即，控制信息对应的传输参数可以是网络设备配置给第二设备的，或者也可以是第二设备通过预配置的信息获取的。例如，该控制信息对应的传输参数可以是第一设备和第二设备可以根据预配置信息来确定的；或者，第二设备从第一设备接收到的控制信息中获取的；或者是第一设备和第二设备通过协议预定义好的。
在本实施例中，当第二设备获取到网络设备的配置指令或者预配置信息时，第二设备可以根据该配置信息确定每个控制信息对应的传输参数配置信息，进而再根据该传输参数配置信息确定出该控制信息对应的传输参数。
关于根据网络设备的配置指令或者预配置的信息获取控制信息对应的传输参数的有益效果可以参见上述步骤21中的记载，此处不再赘述。
步骤25：第二设备根据该控制信息对应的传输参数，确定该控制信息对应的重传指示信息。
本申请实施例提供的通信方法，第一设备获取M个控制信息中每个控制信息所对应的传输参数配置信息，根据该M个控制信息中每个控制信息所对应的传输参数配置信息发送该M个控制信息，相应的，第二设备接收控制信息，该控制信息为上述M个控制信息中的一个，并获取该控制信息对应的传输参数，根据该控制信息对应的传输参数确定该控制信息对应的重传指示信息，由于该M个控制信息中每个控制信息所对应的传输参数配置信息不同，每个传输参数配置信息包括：重传指示信息，该重传指示信息用于指示对应的控制信息是否为重传信息和/或用于指示对应的控制信息在N次传输中的第a次重传，其减少了第二设备的盲检次数，降低了对第二设备的缓存要求，提高了第二设备的检测性能和检测成功率。
进一步地，本申请的实施例中，上述M个控制信息关联到同一个被调度的数据信息。
在高可靠低时延场景中，为了实现高可靠地传输的信息(包括：控制信息和数据信息)，某个控制信息可能会被重复发送，其用于调度的是同一个数据信息，所以，若第一设备发送的M个控制信息均是为了指示某个数据信息，那么该M个控制信息会关联到同一个被调度的数据信息。当第二设备接收到上述M个控制信息中的任意一个且能成功解调时，第二设备则不需要再解调其他的控制信息，提高了第二设备的检测效率和检测成功率。
值得说明的是，控制信息所调度的数据可以是下行数据，也可以是上行数据，还可以是边链路上的数据。本申请实施例并不限定控制信息所调度的数据的具体类型。
示例性的，上述M个控制信息中的内容相同。
在本实施例中，为了使第二设备可以对接收到的多个控制信息在译码前进行直接合并， 首先需要保证接收到的上述M个控制信息中的内容相同，也即，多次重复传输的控制信息的内容相同。在第二设备对多份内容相同的接收数据做合并后可以获得更高的接收信噪比，从而提高译码的成功概率。只有这样，第二设备在对接收到的控制信息译码前才能够在识别出当前传输是否有重传信息、重传信息分别是第几次重传的时候直接将确定出的各个重传信息直接合并。
例如，第1个控制信息指示其到数据信息所在的时域位置起点的时隙偏移值为3，第2个控制信息指示其到数据信息所在的时域位置起点的时隙偏移值为2。如果按实际情况来设置物理下行控制信道(physical downlink control channel，PDCCH)中的时隙偏移的指示值，即这2个控制信息中的内容就会不同，从而导致第二设备不能够直接将这两个控制信息对应的待解调数据进行直接合并接收和译码。所以，网络设备可以通过配置指令的形式指示或预定义的方式确定是以第1个还是以第2个控制信息的值为“真实”值，并使另一个控制信息中的值与之相同。
可以理解的是，本实施例中的时域位置还可以用时频位置表示，则本实施例中的时频位置包括：时域位置，或者频域位置，或者时域和频域联合确定的资源的位置。当在本发明中未做特别说明时，时频位置包括以上三种情况。
同样的，对于频域位置，与时域位置类似，为了方便控制信息的合并，多个重传的控制信息中的内容相同。这包括多个重传的控制信息中指示的频域位置相同，当实际传输中，如果每个控制信息所调度的数据位置不同时，则每个控制信息所调度的数据频域位置由其所指示的频域位置加上一个信令配置的或预定义的频域偏移值来确定。或者如果每个控制信息所调度的数据位置不同时，则每个控制信息所调度的数据频域位置由其所指示的频域位置按预定义的跳频模式来计算得到。
进一步地，具有相同内容的控制信息可以按时域和频域的指示方法来联合指示同时被调度数据的时域和频域位置。
或者，在另一个实施方式中，也可以将多个控制信息中的多个重传信息置于同一个时隙中，这样，各个控制信息中的内容也正好可以相同，其恰好可以关联到同一个被调度的数据。
可选地，多次重传的控制信息的内容来自于同一个数据包或传输块，每次重传的内容可以完全相同，也可以为同一个数据包的不同的冗余版本。
进一步地，在本申请的实施例中，该通信方法还包括如下步骤：
第一设备或第二设备根据网络设备的配置指令或预配置的信息，确定M个控制信息中用于指示数据信息所在的时域位置起点的控制信息。
例如，M个控制信息中用于指示数据信息所在的时域位置起点的控制信息可以是网络设备配置给第一设备或第二设备的，或者也可以是预配置的信息获取的。
示例性的，在本实施例中，可以通过网络设备的配置信令的形式提前指示或通过第一设备和第二设备预先规定配置信息的方式确定多个重传的控制信息中用于指示数据信息所在的时域位置起点的是哪一个控制信息。
例如：如果以第1个控制信息指示的数据信息所在时域位置起点为“真”时，则第2个控制信息指示的数据信息所在的时域位置的起点则为“假”。若通过网络设备的配置指令或第一设备和第二设备预先规定的配置信息指示出M个控制信息中用于指示数据信息所在 的时域位置起点的控制信息，且第二设备可以判断出每个控制信息时传输中的第几次重传，从而可以准确地知道指示控制信息中指示的数据信息所在时域位置起点是哪一个，也即哪一个控制信息指示的数据信息所在时域位置的开始位置是有效的。这样，第二设备可以在不需要做盲检的情况下直接合并多个重传的控制信息，提高了检测效率。
示例性的，在本申请的实施例中，上述M个控制信息中的至少一个控制信息所在的时域位置位于所关联的被调度的数据信息所在的时域位置之前。
具体的，在本实施例中，为了减少对数据信息的缓存，可以第一设备在发送控制信息时可以将发送的M个控制信息中的至少一个放在其所调度的数据信息的前面发送，即控制M个控制信息中的至少一个控制信息所在的时域位置位于所关联的被调度的数据信息所在的时域位置之前。
在本实施例中，该M个控制信息中的至少一个控制信息所在的时域位置位于所关联的被调度的数据信息所在的时域位置之前，具体可以通过如下方式实现：
作为一种示例，M个控制信息所在的时域位置全部位于所关联的被调度的数据信息所在的时域位置之前。
示例性的，M个控制信息关联到同一个被调度的数据信息，为了使得第二设备在检测到数据信息之前能够对接收到的控制信息译码，网络设备可以通过配置指令或者通过第一设备和第二设备规定的配置信息，使得M个控制信息所在的时域位置全部位于所关联的被调度的数据信息所在的时域位置之前，这样可以最大程度的提高第二设备的检测效率，提高第二设备接收数据信息的可靠性，缩短第二设备获取到数据信息的时延。
例如，在时域上，当控制信息承载在时频资源上时，假设第一资源上承载的是第一控制信息，第二资源上承载的是第二控制信息，该第一控制信息和第二控制信息用于调度同一个数据信息。
下述图3a至图3d以两个控制信息举例说明控制信息与所关联的被调度的数据信息在时域上的位置关系。示例性的，图3a至图3d为两个控制信息与所关联的被调度的数据信息的时域位置关系示意图。该图3a至图3d中的示意图中，第一个方框C表示用于承载第一个控制信息的第一时频资源，第二个方框C表示用于承载第二个控制信息的第二时频资源，方框D表示用于承载第一个控制信息和第二个控制信息调度的数据信息，第二个控制信息是第一个控制信息的重传信息。若控制信息调度两个数据信息，则通过解调控制信息的内容，可以获知第一个数据信息和第二个数据信息的位置，该第二个数据信息可以与第一个数据信息相同，也可以与第1个数据信息不同，本实施例并不对其进行限定。
具体的，图3a示例性的示出了2个在时域上连续的控制信息调度同一个数据信息，承载控制信息的时频资源位于承载数据信息的时频资源之前，且承载控制信息的时频资源与承载数据信息的时频资源在时域上是否连续，本申请并不对其进行限定。
图3b示例性的示出了两个在时域上连续的控制信息调度两个数据信息。示例性的，这两个数据信息所占用的时频位置可以通过调度它们的控制信息来指示，通过解调这两个控制信息便可以确定出承载每个数据信息的时域资源。
图3c示例性的示出了两个在时域上不连续的控制信息调度同一个数据信息。图3d示例性的示出了两个在时域上不连续的控制信息调度两个数据信息。
图3a至图3d中的示意图只示例性的给出了控制信息与数据信息在时域上的几种位置关 系，本申请实施例并不以此为限制。
值得说明的是，本实施例中，同一控制信息的发送次数可以还大于2次，如4次、6次、8次等。每个控制信息与数据信息所在的频域资源位置可以相同，也可以不同。本申请实施例并不能因为上述图形而对此有所限定。
作为另一种示例，M个控制信息中的一部分控制信息所在的时域位置位于所关联的被调度的第一部分数据信息所在的时域位置之前，该M个控制信息中的另一部分控制信息所在的时域位置位于第一部分数据信息所在的时域位置之后且位于第二部分数据信息所在的时域位置之前，且该第一部分数据信息和第二部分数据信息组成上述数据信息。
示例性的，本实施例中，网络设备可以通过配置指令或者通过预配置的信息使得M个控制信息中的某部分控制信息所在的时域位置位于所关联的被调度的数据信息之间，例如，将数据信息分成第一部分数据信息和第二部分数据信息等两个组成部分，且第一部分数据信息在时域上位于第二部分数据信息的前面，这样也可以提高第二设备的检测效率，提高第二设备接收数据信息的可靠性，缩短第二设备获取到数据信息的时延。
例如，下述图4a和图4b仍以两个控制信息举例说明控制信息与所关联的被调度的数据信息在时域上的位置关系。图4a和图4b为两个控制信息与第一部分数据信息、第二部分数据信息的时域位置关系示意图。该图4a和图4b中的示意图中，第二个控制信息仍然是第一个控制信息的重传信息。
具体的，图4a示例性的示出了2个在时域上不连续的控制信息调度被分离成两个部分的数据信息(第一部分数据信息和第二部分数据信息)，其中，控制信息和数据信息在时域上连续。图4b示例性的示出了两个在时域上不连续的控制信息调度被分离成两个部分的数据信息(第一部分数据信息和第二部分数据信息)，其中，控制信息和数据信息在时域上也不连续。
值得说明的是，在该种可能实现方式下，需要保证控制信息与所调度的数据信息的各个部分之间的时间间隔相同，或者各个控制信息所在的时隙与各个数据信息所在的时隙和/或符号的间隔相同。
示例性的，分开的多个数据可以是同一个数据信道被分成了多个部分映射到不同的时域符号上，也可以是同一个数据的不同的重传版本，还可以是同一个数据包完全相同的内容。当数据被分成多个部分时，每个部分的频率位置相同，或者按预设的规定进行一一对应。当按预设的规定进行一一对应时，控制信息指示的为其中一个(例如第一个)数据部分所在的频域位置，其它数据部分按对应关系进行确定。
上述详细说明了控制信息与所关联的被调度的数据信息的关系示意图，下述主要介绍如何通过控制信息对应的传输参数配置信息作为重传指示信息来指示对应的控制信息是否为重传信息和/或对应控制信息在N次传输中的第几次重传。
在实际应用中，控制信息可以承载于控制信道，如蜂窝网络链路的下行为PDCCH、物理广播信道(physical broadcast channel，PBCH)，蜂窝网络链路的上行可以是物理上行控制信道(physical uplink control channel，PUCCH)；边链路(sidelink)的控制信息可以承载于物理边链路共享信道(physical sidelink share channel，PSSCH)、物理边链路控制信道(physical sidelink control channel，PSCCH)、物理边链路广播信道(physical sidelink broadcast channel，PSBCH)。作为另一种实现方式，控制信息可以承载于数据信道，如蜂 窝网络链路的下行为物理下行共享信道(physical downlink share channel，PDSCH)，蜂窝链路的上行可以是物理上行共享信道(physical uplink share channel，PUSCH)；边链路的控制信息可以承载于PSSCH。本实施例对承载控制信息的信道不做限定，其可以根据实际情况进行确定和选择。
在本实施例的一种可能实现方式中，控制信息也可以承载于参考信号中。不同的参考信号序列对应控制信息的不同取值状态。例如，要指示2比特的信息，可以使用4个不同的参考信号序列来对应4种不同的状态。当使用参考信号来指示承载的控制信息重传时，在传输过程中要发送多次参考信号。
在本实施例中，对于进行多次传输的控制信息，在时域上，每个控制信息承载在特定数量(如1个符号到14个符号中的任意一种配置)的符号或时隙中，每次传输占用一个时隙或若干个符号，而且多次传输的控制信息，其所在的时域位置可以有多种形式。图5a至图5c为多个控制信息所在的频域位置的关系示意图。具体的，对于传输的多个控制信息，图5a示例性的示出了每个控制信息所在的时域位置可以是均不连续的，图5b示例性的示出了每两个控制信息所在的时域位置可以是连续的，图5c示例性的示出了所有重传的控制信息所在的时域位置可以是依次连续的。
进一步的，对于进行多次传输的控制信息，在频域上，所有传输的控制信息在各次传输时所占用的频域位置可以全部相同，可以部分相同，也可以全部不相同，本申请实施例并不对控制信息所占用的频域位置进行限定。
在本实施例中，由于传输参数配置信息包括重传指示信息，也即，该重传指示信息可以承载在传输参数配置信息中的用于解调对应控制信息的参考信号中，也可以承载在传输参数配置信息中的对应控制信息的资源中。具体分别解释如下：
作为一种示例，该重传指示信息承载在用于解调对应控制信息的参考信号中。
其中，该参考信号的信息至少包括如下的任意一种：参考信号映射到的频率位置或生成参考信号的序列。
示例性的，重传指示信息可以利用参考信号映射到的频率位置来指示。
在本实施例的一种可能实现方式中，对于上述M个控制信息中的每个控制信息，可以通过在5G NR的协议中增加一个参数a，利用该参数a的取值作为该控制信息在系统规定的N次传输中的第a次重传。具体的，利用参数a指示某一个天线端口P在频域上映射时按参数的a值做相应的移动，本实施例中以参考信号为解调参考信号(demodulation reference signal，DMRS)，控制信道为PDSCH进行解释说明。示例性的，对于某个控制信息，其对应的子载波配置参数μ，在第p个天线端口上的资源RE为(k,l)时的DMRS序列值
Figure PCTCN2019096003-appb-000001
可以表示如下：
Figure PCTCN2019096003-appb-000002
其中，
Figure PCTCN2019096003-appb-000003
k′＝0,1，
Figure PCTCN2019096003-appb-000004
n＝0,1,…。
Figure PCTCN2019096003-appb-000005
表示DMRS在传输过程中的传输功率参数，ω f(k′)通过k′＝0,1来表示配置类型1上的2个循环移位(cyclic shift，CS)复用，或者配置类型2上的频域正交覆盖码(frequency domain orthogonal cover code，FD-OCC)效果，a1和a2分别对应配置类型1的 DMRS和配置类型2的DMRS，a1和a2取不同的值，可以用于表示PDCCH上承载的控制信息对应传输过程中的第几次重传。例如，0代表第1次重传，1代表第2次重传，2代表第3次重传。
值得说明的是，在上述公式中，k表示生成参考信号时，在一个RB内的频域位置的中间变量；l表示数据或参考信号所在的符号位置；f表示频域方向，t表示时域方向，n为计算频域位置偏移值的中间变量，ω t(l′)表示时域的OCC序列，ω f(k′)表示频域的OCC序列，Δ表示频域偏移值，r(2n+k′)表示在频域上的参考信号。
示例性的，图6a至图6d为参考信号映射到的频率位置的分布示意图。具体的，对于配置类型不同的参考信号，参考信号映射到的频率位置可以不同，本实施例中以参考信号为DMRS进行举例说明。图6a示例性的示出了天线最大可支持4端口时，配置类型为1的DMRS映射到的频率位置，图6b示例性的示出了天线最大可支持8端口时，配置类型为1的DMRS映射到的频率位置，图6c示例性的示出了天线最大可支持6端口时，配置类型为2的DMRS映射到的频率位置，图6d示例性的示出了天线最大可支持12端口时，配置类型为2的DMRS映射到的频率位置。参照图6a至图6d，根据DMRS的配置类型可以获知DMRS映射到的频率位置。
在本实施例的另一种可能实现方式中，本实施例将重传指示信息承载在NR-PDCCH中，具体的，NR-PDCCH的一种修改结构如下：
Figure PCTCN2019096003-appb-000006
其中，
Figure PCTCN2019096003-appb-000007
由参数Δ来生成，对应不同的重传指示信息的值。r l(3n+k′)表示频域上的第l个符号位置上的参考信号。对于该公式中未说明的参数的含义与上述公式中的类似，此处不再赘述。
示例性的，生成序列的序列跳v或序列组跳f gh的公式，可以由重传指示信息Δ确定。
一种序列组跳f gh和序列跳v生成方式如下：
Figure PCTCN2019096003-appb-000008
v＝0
另一种序列跳v的生成方式如下：
Figure PCTCN2019096003-appb-000009
c()为一随机序列，
Figure PCTCN2019096003-appb-000010
表示一个时隙中的符号数，
Figure PCTCN2019096003-appb-000011
表示一个时隙中的第几个时隙，l表示符号数，M ZC表示序列的长度，m为中间变量。
进一步地，当通信系统中同时存在有控制信息重传和控制信息不做重传的混合场景。此时，可以使用参考信号映射到的频率位置或生成参考信号的序列的组合方式来指示对应控制信息的重传指示信息。或者可以使用生成参考信号的序列的不同的参数的取值组合的方式来指示对应控制信息的重传指示信息。
例如，对于基于随机序列的场景，可以使用DMRS映射到的不同频域位置来指示对应的控制信息是否做重传。比如，DMRS映射到的第一种频率位置表示对应的控制信息不是重传信息(资源偏移等于0)；DMRS映射到的第二种频率位置表示对应的控制信息是重传信息(资源偏移等于1或2)。
示例性的，在本实施例中，也可以使用生成DMRS序列的不同参数作为对应控制信息的重传指示信息。
例如，可以使用DMRS序列的不同参数(生成序列的初始值)指示是否做重传，使用生成DMRS的序列在频域中的不同位置来指示对应的控制信息在整个传输中的第几次重传。
示例性的，对于使用ZC序列的场景，可以使用ZC序列的不同参数组合作为重传指示信息。
例如：使用不同的根序列号的偏移值来指示是否做重传，使用同一个根序列下的不同的循环移位值来指示对应的控制信息在整个传输中的第几次重传。
再比如：使用不同的循环移位值来指示是否做重传，使用同一个循环移位值下的不同的根序列号的偏移值来指示重传的次数(即对应的控制信息在N次传输中的第几次重传)。
在本实施例中，通过将重传指示信息承载在用于解调对应控制信息的参考信号中，该参考信号的信息至少包括如下的任意一种：参考信号映射到的频率位置或生成该参考信号的序列，这样可以接收控制信息的第二设备在解调控制信息之前通过对参考信号的参数进行估计就可以得到控制信息对应的重传指示信息，进而确定该控制信息是否为重传信息和/或在整个传输中的第几次重传，从而可以在控制信息进行多次重传时，减少第二设备的缓存，提高控制信息的检测速度，减少处理时延。
作为另一种示例，该重传指示信息由用于承载对应控制信息的资源指示。
其中，该资源至少包括如下的任意一种：控制信息对应的搜索空间参数或控制信息对应的控制资源集合。
示例性的，该重传指示信息可以由控制信息对应的搜索空间参数来指示。
其中，该搜索空间参数至少包括如下任意一种：搜索空间的标识、搜索空间的周期和时隙位置、持续连续符号数、时隙中的时域符号数或汇聚级别。
具体的，可以使用不同的传输资源来指示对应的控制信息是否为重传信息和/或对应的控制为整个传输中的第几次重传。
例如，对于PDCCH的重传，可以使用以下方式来指示是否有重传。
在第一种可能的实施方式中：可以为非重复传输的PDCCH和重复传输的PDCCH的配置不同的搜索空间。例如，可以通过网络设备发送的广播信令或RRC消息为非重复传输的PDCCH配置专用的第一搜索空间，为重复传输的PDCCH配置专用的第二搜索空间。
其中，第一搜索空间和第二搜索空间以下参数中的至少一种不同：搜索空间的标识、搜索空间的周期和时隙位置、持续连续符号数、时隙中的时域符号数、汇聚级别。
在第二种可能的实施方式中，可以为重复传输的PDCCH对应的不同传输次数配置不同的搜索空间。
可以理解的是，该种可能实施方式可以独立于上述第一种可能的实施方式执行，也可以与第一种可能的实施方式结合实施，本实施例并不对其进行限定。
对于重复传输的PDCCH，若利用不同的搜索空间表示对应的PDCCH的重传次数，则为重复传输的PDCCH配置的不同搜索空间的参数至少有一种不同。
例如：当需要指示不同的PDCCH对应的重传次数时，不同的重传次数可以占用同一个PDCCH搜索空间周期中的不同时隙，或同一个时隙中的不同符号。同样的，在指示不同的PDCCH对应的重传次数时，还可以使用一个或多个时隙中的不同符号位置来表示。
图7a和图7b为不同控制信息对应的重传指示信息占用的不同传输时隙的分布示意图。图7a示例性的示出了PDCCH对应的不同重传次数占用PDCCH监测周期内的不同时隙位置，如图7a所示，PDCCH的不同重传次数可以占用同一个PDCCH监测周期内的不同时隙偏移量。图7b示例性的示出了PDCCH对应的不同传输次数占用同一个时隙中的不同符号位置，如图7b所示，假设每一个PDCCH重传占用2个OFDM符号，则不同的PDCCH重传可以占用多个连续或不连续的OFDM符号，图7b中以每个PDCCH重传占用2个连续的OFDM符号为例进行说明。
示例性的，该重传指示信息可以由控制信息对应的控制资源集合来指示。
其中，该控制资源集合至少包括如下任意一种：控制资源集合的标识、控制资源集合对应的频域资源位置或控制资源集合占用的连续的时间长度。
具体的，可以使用控制资源集合(control resource set，CORESET)来指示对应的控制信息是否为重传信息和/或对应的控制信息在整个传输中的第几次重传。示例性的，可以使用以下参数中的至少一种来指示上述信息：CORESET标识、频域资源位置、CORESET占用的连续的时间长度。该参数中的任意一种的不同取值可以用来指示是否进行非重传或重传，也可以用来指示在整个传输中的第几次重传，还可以使用一种来指示是否为重传信息，其余的一个或多个参数来指示在整个传输中的第几次重传。
例如，可以使用CORESET标识1来指示对应的PDCCH不是重传信息，使用CORESET标识2来指示对应的PDCCH是重传信息，此时，可以使用CORSET占用的连续的时间长度的取值指示对应的PDCCH的第几次重传。比如，CORSET占用2个符号表示第1次重传，CORSET占用3个符号表示第2次重传，CORSET占用4个符号表示第3次重传，CORSET占用5个符号表示第4次传输等。
同样地，在使用CORESET标识1来指示对应的PDCCH不是重传信息，使用CORESET标识2来指示对应的PDCCH是重传信息时，也可以使用CORSET占用的频域资源位置来指示对应的PDCCH的第几次重传。比如，CORSET占用第1频域子集表示第1次重传；CORSET占第2频域子集表示第1次重传；CORSET占用第3频域子集表示第3次重传；CORSET占第4频域子集表示第4次重传。
在本实施例的另一可能实现方式中，可以使用CORESET以及搜索空间参数来联合指示对应的控制信息是否为重传信息和/或对应的控制信息的第几次重传。
例如，可以使用CORSET中的任意一种参数指示对应的控制信息是否为重传信息，使用搜索空间中的任意一种参数来指示对应的控制信息的第几次重传。
对于本实施例中的第二设备，第二设备可以根据网络设备的配置指令或预配置的信息，获取每个控制信息对应的传输参数配置信息，该传输参数配置信息中的包括用于指示对应的控制是否为重传信息和/或对应的控制信息的第几次重传的重传指示信息，例如，CORESET和搜索空间参数的配置信息，然后根据这些配置信息在相应的资源上检测PDCCH的单次传输和重复传输。
在本实施例中，利用CORESET和搜索空间参数的配置信息分别或组合来指示PDCCH的单次传输和重复传输以及当前的重复次数，可以减少第二设备的盲检测次数，降低检测复杂度。
