Description

一种反馈信息的传输方法和通信设备
相关申请的交叉引用
本申请要求在2020年09月30日提交中国专利局、申请号为202011064466.X、申请名称为“一种反馈信息的传输方法和通信设备”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
本申请涉及无线通信技术领域，尤其涉及一种反馈信息的传输方法和通信设备。
背景技术
5G新无线(new radio，NR)通信系统相比于前几代移动通信系统在传输速率、时延及功耗等方面都提出了更高的要求。国际电信联盟(international telecommunication union，ITU)将增强型移动宽带(enhanced mobile broadband，EMBB)、海量机器类型通信(massive machine type communication，MMTC)和超可靠低延迟通信(ultra-reliable and low-latency communication，URLLC)定义为未来5G的三大典型业务。
URLLC作为三大典型业务之一，主要可以应用于无人驾驶、远程医疗等。这些应用场景在可靠性及延时方面提出了严格的要求。因此，如何能够保证URLLC的可靠性和时延要求，成为倍受关注的问题。
例如，执行URLLC和EMBB业务时，终端设备在接收到相应的数据时可以分别发送数据所对应的反馈信息，在URLLC业务有反馈信息需要发送时，不需要等到EMBB业务的反馈信息一起发送，从而能够避免在一个物理上行控制信道(physical uplink control channel，PUCCH)资源上承载过多的比特数，从而保证URLLC的反馈信息的可靠性。
目前，终端设备支持多个反馈信息采用时分复用的方式传输。即，终端设备可以将多个反馈信息在同一时隙上进行复用传输。然而，一个时隙能够复用传输的反馈信息数量是有限制的，如果终端设备在一个时隙上待复用传输的反馈信息的数量超过上述数量限制时，会按照接收数据的时间顺序复用传输对应的多个反馈信息。这样，可能导致一些业务对应的反馈信息得不到及时反馈给发送端，影响业务的性能。
发明内容
本申请提供一种反馈信息的传输方法和通信设备，用以提高超可靠低延迟通信业务的反馈信息的反馈效率，提高超可靠低延迟通信业务的性能。
第一方面，提供了一种反馈信息的传输方法。该方法可以由本申请实施例提供的通信设备执行。该通信设备可以是终端设备或网络设备，或者也可以是类似于终端设备或网络设备的功能的芯片。该方法中，通信设备可以接收至少一个数据信息。其中，至少一个数据信息可以具有相应的至少一个覆盖增强等级。通信设备可以基于至少一个数据信息的覆盖增强等级，将对应的至少一个数据信息的反馈信息复用于控制信息。通信设备可以在第一控制信道或者第一数据信道发送该控制信息。
基于上述方案，可以根据数据信息的覆盖增强等级将数据信息的反馈信息复用于控制信息传输，可以根据覆盖增强等级确定反馈信息的发送顺序，可以有效处理反馈信息的冲突，保障一些高时延要求的业务的性能。
在一种可能的实现方式中，控制信息中包含的反馈信息的数量不超过通信设备能够复用的反馈信息的阈值。
基于上述方案，可以根据通信设备能够复用的反馈信息的阈值，限制复用的反馈信息的数量。
在一种可能的实现方式中，通信设备可以上报能够复用的反馈信息的数量。
基于该方案，通信设备可以上报能够复用的反馈信息的数量，因此可以根据上报的能够复用的反馈信息的数量，限制通信设备在一个控制信息内复用的反馈信息的数量。
在一种可能的实现方式中，前述通信设备能够复用的反馈信息的阈值为基于通信设备上报的能够复用的反馈信息的数量确定的。
基于该方案，可以根据通信设备上报的阈值确定通信设备能够复用的反馈信息的数量，从而限制通信设备在一个控制信息上复用的反馈信息的数量。
在一种可能的实现方式中，通信设备可以按照至少一个数据信息的覆盖增强等级从高到底的顺序，将对应的至少一个数据信息的反馈信息复用于控制信息。
基于上述方案，通信设备在将数据信息的反馈信息复用于控制信息时，可以按照数据信息的覆盖增强等级从高到低的顺序，将反馈信息复用于控制信息，可以优先的保障高时延的业务的性能。
在一种可能的实现方式中，通信设备可以将覆盖增强等级相同的至少一个数据信息对应的至少一个反馈信息复用于所述控制信息。
基于该方案，通信设备可以在控制信息中将覆盖增强等级相同的至少一个数据信息对应的至少一个反馈信息进行复用，而保障一些业务的性能。
在一种可能的实现方式中，通信设备可以将具有第一覆盖增强等级的至少一个数据信息对应的至少一个反馈信息和具有至少一个第二覆盖增强等级的至少一个数据信息对应的至少一个反馈信息，复用于控制信息。这里的至少一个第二覆盖增强等级低于第一覆盖增强等级。
基于该方案，通信设备可以在控制信息上复用覆盖增强等级不相同的数据信息的反馈信息，可以在保障业务的性能的同时节省传输资源。
在一种可能的实现方式中，通信设备可以确定至少一个数据信息的覆盖增强等级均小于或等于预设门限。
基于该方案，覆盖增强等级均小于或等于预设门限时，表示覆盖增强等级不是很高，因此可以高低级别分别对待。通信设备可以优先反馈覆盖增强等级较高的数据信息的反馈信息，再反馈覆盖增强等级较低的数据信息的反馈信息，可以在保障高时延要求的业务的性能的同时，不影响其他业务的性能。
在一种可能的实现方式中，在至少一个数据信息的覆盖增强等级均大于或等于预设门限时，通信设备按照至少一个数据信息的接收顺序，将至少一个数据信息的反馈信息复用于控制信息。
基于该方案，覆盖增强等级大于或等于预设门限时，表示覆盖增强等级都比较高，因此可以直接按照数据信息的接收顺序反馈数据信息的反馈信息。通信设备可以通过数据信 息的接收顺序先后将反馈信息复用于控制信息，减少复杂度，保证高优先级的数据信息的反馈信息可以依次得到反馈。
在一种可能的实现方式中，通信设备可以在第一时隙中的所述第一控制信道或第一数据信道发送控制信息；或者，通信设备可以在第一时隙以及第一时隙之后的至少一个时隙中的第一控制信道或第一数据信道发送该控制信息。
基于该方案，通信设备可以将至少一个数据信息的反馈信息复用于控制信息后，在第一时隙以及第一时隙之后的至少一个时隙中的第一控制信道或第一数据信道发送控制信息。
在一种可能的实现方式中，通信设备可以将至少一个数据信息的反馈信息复用于第一时隙中的控制信息；或者，通信设备可以将至少一个数据信息的反馈信息复用于第一时隙以及所述第一时隙后的至少一个时隙中的控制信息。
基于该方案，通信设备可以将至少一个数据信息的反馈信息复用于第一时隙以及第一时隙之后的至少一个时隙中的控制信息中进行传输，可以提高高时延要求的业务的性能。
第二方面，提供了一种反馈信息的传输方法。该方法可以由本申请实施例提供的通信设备执行。该通信设备可以是终端设备或网络设备，或者也可以是类似于终端设备或网络设备的功能的芯片。该方法中，通信设备可以接收至少一个数据信息。这里的至少一个数据信息包括具有相应的至少一个覆盖增强等级的数据信息和没有覆盖增强等级的数据信息。其中，没有覆盖增强等级的数据信息可以认为是覆盖增强等级为零的数据信息，或者覆盖增强等级最低的数据信息。通信设备可以基于至少一个数据信息的覆盖增强等级，将至少一个数据信息对应的反馈信息复用于控制信息。通信设备可以在第一控制信道或第一数据信息发送该控制信息。
在一种可能的实现方式中，控制信息中包含的反馈信息的数量不超过通信设备能够复用的反馈信息的阈值。
在一种可能的实现方式中，通信设备可以上报能够复用的反馈信息的数量。
在一种可能的实现方式中，前述通信设备能够复用的反馈信息的阈值为基于通信设备上报的能够复用的反馈信息的数量确定的。
在一种可能的实现方式中，通信设备可以按照至少一个数据信息的覆盖增强等级从高到底的顺序，将对应的至少一个数据信息的反馈信息复用于控制信息。

在一种可能的实现方式中，通信设备可以将至少一个数据信息的反馈信息复用于第一时隙中的控制信息；或者，通信设备可以将至少一个数据信息的反馈信息复用于第一时隙以及所述第一时隙后的至少一个时隙中的控制信息。

具体实施方式
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)覆盖增强等级，也可以称为覆盖等级，或者业务等级，或者业务类型等级，或者业务恢复等级，或者增强等级。其中，业务类型包括时延，功耗，速度，调制编码方案或者占用的资源量中至少一种。资源量，可以理解为物理资源块(physical resource block，PRB)数目，或正交频分复用技术(orthogonal frequency division multiplexing，OFDM)符号数，以及PRB和符号数的组合。在实际组网中，小区边缘面临着来自其他小区的较大程度的干扰，通过蜂窝通信技术可以实现覆盖增强和降低时延的目的。
2)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上， 其它量词与之类似。“和/或”描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，对于单数形式“a”，“an”和“the”出现的元素(element)，除非上下文另有明确规定，否则其不意味着“一个或仅一个”，而是意味着“一个或多于一个”。例如，“a device”意味着对一个或多个这样的device。再者，至少一个(at least one of).......”意味着后续关联对象中的一个或任意组合，例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC，或ABC。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统，全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统，未来的第五代(5th Generation，5G)系统，如新一代无线接入技术(new radio access technology，NR)，及未来的通信系统，如6G系统等。
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
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的说明本申请实施例的技术方案，并不构成对于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。
本申请实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或传输接收点(Transmission and Reception Point,TRP)，并与一个集中控制器(controller)相连。当UE在Hyper cell内移动时，网络侧设备为UE选择新的sub-cluster(子簇)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。或者是，在以UE为中心的网络中，多个网络侧设备，如小站，可以有独立的控制器，如分布式控制器，各小站能够独立调度用户，小站之间在长期上存在交互信息，使得在为UE提供协作服务时，也能够有一定的灵活性。
本申请实施例中不同基站可以为具有不同的标识的基站，也可以为具有相同的标识的被部署在不同地理位置的基站。由于在基站被部署前，基站并不会知道其是否会涉及本申请实施例所应用的场景，因而，基站，或基带芯片，都应在部署前就支持本申请实施例所提供的方法。可以理解的是，前述具有不同标识的基站可以为基站标识，也可以为小区标识或者其他标识。
本申请实施例中部分场景以无线通信网络中NR网络的场景为例进行说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
本申请中，通信设备可以是终端设备，或者网络设备。当通信设备为终端设备时，该终端设备复用的是针对物理下行共享信道(physical downlink shared channel，PDSCH)的反馈信息；当通信设备为网络设备时，该网络设备复用的是针对上行物理共享信道(physical uplink shared channel，PUSCH)的反馈信息。
另外需要说明的是，当该通信设备为终端设备时，终端设备可以向网络设备上报能够复用的反馈信息的数量。
本申请实施例提供的技术方案可以应用于通信设备间的无线通信。通信设备间的无线通信可以包括：网络设备和终端设备间的无线通信、网络设备和网络设备间的无线通信以及终端设备和终端设备间的无线通信。其中，在本申请实施例中，术语“无线通信”还可以简称为“通信”，术语“通信”还可以描述为“数据传输”、“信息传输”或“传输”。
为便于理解本申请实施例，首先以图1示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1示出了适用于本申请实施例的通信方法的通信系统的示意图。如图1所示，该通信系统100包括终端设备101和网络设备102。终端设备101和网络设备102可配置有多个天线。可选的，该通信系统还可以包括终端设备103，终端设备103也可以配置有多个天线。

作为示例而非限定，在本申请实施例中，该终端还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种终端，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端，车载终端例如也称为车载单元(on-board unit，OBU)。
本申请实施例中，用于实现终端的功能的装置可以是终端，也可以是能够支持终端实现该功能的装置，例如芯片系统，该装置可以被安装在终端中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中，以用于实现终端的功能的装置是终端为例，描述本申请实施例提供的技术方案。
本申请所涉及的网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端通信的设备，或者例如，一种车到一切(vehicle-to-everything，V2X)技术中的网络设备为路侧单元(road side unit，RSU)。基站可用于将收到的空中帧与IP分组进行相互转换，作为终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如，网络设备可以包括长期演进(long term evolution，LTE)系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括演进的分组核心网络(evolved packet core，EPC)、第五代移动通信技术(the 5th generation，5G)、新空口(new radio，NR)系统(也简称为NR系统)中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
网络设备还可以包括核心网设备，核心网设备例如包括访问和移动管理功能(access and mobility management function，AMF)等。
本申请实施例中，用于实现网络设备的功能的装置可以是网络设备，也可以是能够支持网络设备实现该功能的装置，例如芯片系统，该装置可以被安装在网络设备中。在本申请实施例提供的技术方案中，以用于实现网络设备的功能的装置是网络设备为例，描述本申请实施例提供的技术方案。
目前，通信设备在接收到业务的数据时可以分别发送数据所对应的反馈信息。通信设备支持反馈信息的复用。即，通信设备可以将多个反馈信息在同一时隙上进行传输。然而，一个时隙能够复用传输的反馈信息数量是有限制的，如果通信设备在一个时隙上待复用传输的反馈信息的数量超过上述数量限制时，会按照接收数据的时间顺序复用传输对应的多个反馈信息。这样，可能导致一些业务对应的反馈信息得不到及时反馈给发送端，影响业务的性能。
基于上述问题，本申请实施例提供了一种通信方法。本申请的通信方法可以应用于无线通信系统中，例如，图1所示出的通信系统。该通信系统可以包括至少一个网络设备和至少一个终端设备。网络设备和终端设备可以通过无线空口通信。本申请实施例中的通信设备可以是终端设备，如图1所示的终端设备101、终端设备103，或者通信设备也可以是网络设备，如图1所示的网络设备102。
如图2所示，是以设备交互角度示出的本申请实施例提供的通信方法的示例性流程图，可以包括以下步骤。
步骤201：第一通信设备接收至少一个数据信息。
其中，第一通信设备可以从第二通信设备接收多个数据。这里的第一通信设备可以是网络设备，或者也可以是终端设备。同样的，第二通信设备可以是网络设备也可以是终端设备。这里的通信设备可以接收相同的至少一个数据信息，或者不同的至少一个数据信息。
举例来说，至少一个数据信息可以具有相应的至少一个覆盖增强等级。应理解，没有覆盖增强等级的数据信息可以认为覆盖增强等级为零或者最低。具有相应的至少一个覆盖等级包括覆盖等级为0或者没有覆盖等级。具有相应的至少一个覆盖增强等级，也可以称之为，具有相应的覆盖增强等级。覆盖等级可以通过相应的dB值表示。作为一个示例， 覆盖增强等级为0，可表示需要的覆盖增强为0dB。作为一个示例，覆盖增强等级为1，可表示需要的覆盖增强为2dB。作为一个示例，覆盖增强等级为2，可表示需要的覆盖增强为3dB。作为一个示例，覆盖增强等级为3，可表示需要的覆盖增强为5dB。第二通信设备在向第一通信设备发送一个数据信息时，可以根据该数据信息的覆盖增强等级重复发送该数据信息。此时，第一通信设备接收的至少一个数据信息是相同的数据信息。
又例如，第二通信设备在向第一设备发送数据信息时，一个数据信息可以仅发送一次，不进行重复发送，或者发送一个数据信息的不同冗余版本。此时，第一通信设备接收的至少一个数据信息是不同的。
步骤202：通信设备基于至少一个数据信息的覆盖增强等级，将对应的至少一个数据信息的反馈信息复用于控制信息。
对应的至少一个数据信息的反馈信息，可以理解为至少一个数据信息对应的反馈信息。
通信设备可以将至少一个数据信息的反馈信息复用于第一时隙以及第一时隙之后的至少一个时隙中的控制信息中。其中，至少一个数据信息可以与一个反馈信息相对应。比如，第一通信设备接收到相同的多个数据信息时，第一通信设备可以生成针对该相同的多个数据信息的一个反馈信息。或者，第一通信设备可以针对接收到的不同数据信息，生成对应的各自的反馈信息。或者，第一通信设备接收到一个数据信息的不同冗余版本时，第一通信设备可以生成针对该数据信息的不同冗余版本的一个反馈信息。其中，将至少一个数据信息的反馈信息复用于控制信息可以理解为，将至少一个数据信息的反馈信息承载于控制信息，或者控制信息中包含至少一个数据信息的反馈信息。
通信设备可以维护有覆盖增强等级与数据信息的对应关系，在接收到至少一个数据信息时，可以根据至少一个数据信息的覆盖增强等级将反馈信息复用于控制信息中。网络设备也可以预先配置第一通信设备在一个时隙能够复用的反馈信息的阈值。网络设备可通过无线资源控制(radio resource control，RRC)信令消息将该阈值发送给第一通信设备。第一通信设备在一个时隙能够复用的反馈信息的阈值为第一通信设备在一个时隙能够复用的反馈信息的比特数。因此，第一通信设备在步骤203中，在控制信息中复用的反馈信息的总数量应小于或等于该阈值。可选的，该阈值可以是协议规定的。
在一示例中，上述阈值可以是根据通信设备上报的能够复用的反馈信息的数量确定的。例如，该阈值可以与通信设备上报的能够复用的反馈信息的数量相同，或者该阈值可以为以通信设备所上报的能够复用的反馈信息的数量为变量的函数。
以下，具体介绍第一通信设备根据覆盖增强等级将反馈信息复用于控制信息的方法，可以包括方法1-方法4。可选的，在本申请实施例中覆盖增强等级越高，覆盖增强等级值越低；覆盖增强等级越低，覆盖增强等级值越高。例如，覆盖增强等级值1、2和3中，覆盖增强等级值为1的覆盖增强等级最高，覆盖增强等级值为2的覆盖增强等级次高，覆盖增强等级值为3的覆盖增强等级最低。或者，覆盖增强等级越高，覆盖增强等级值越高；覆盖增强等级越低，覆盖增强等级值越低。例如，覆盖增强等级值为3的覆盖增强等级最高，覆盖增强等级值为2的覆盖增强等级次高，覆盖增强等级值为1的覆盖增强等级最低。下述以第一种情形为例，对方法1-4进行具体说明。
方法1：按照至少一个数据信息的覆盖增强等级从高到低的顺序，将对应的至少一个数据信息的反馈信息复用于所述控制信息。
举例来说，第一通信设备接收到数据信息1、数据信息2和数据信息3。其中，数据 信息1的覆盖增强等级为最高等级(如1级)，数据信息2的覆盖增强等级为最高等级(如1级)，数据信息3的覆盖增强等级为次高等级(如2级)。第一通信设备能够复用的反馈信息的阈值为2。因此，第一通信设备可以将数据信息1和数据信息2的反馈信息复用于第一控制信息中，并在第一时隙上发送该第一控制信息。第一通信设备可以将数据3的反馈信息承载于第二控制信息，并在第一时隙之后的一个时隙上发送该第二控制信息。
在一个示例中，第一通信设备可以根据接收到的同一数据信息的总数量，确定该数据信息的覆盖增强等级。举例来说，第一通信设备接收到了数据信息1的总数量为4，数据信息2的总数量为2，数据信息3的总数量为1。因此，第一通信设备可以确定数据信息1的覆盖增强等级高于数据信息2的覆盖增强等级，数据信息2的覆盖增强等级高于数据信息3的覆盖增强等级。
可选的，第一通信设备也可以根据数据信息中携带的标识信息确定覆盖增强等级。该标识信息可以表征该数据所属的业务。其中，第一通信设备可以预先存储标识信息与覆盖增强等级之间的对应关系。因此，第一通信设备在接收到数据信息时，可以根据该标识信息查找对应的覆盖增强等级。
参阅图3，第一通信设备接收到重复次数为1的数据信息1，重复次数为2的数据信息2，重复次数为2的数据信息3和重复次数为1的数据信息4。因此，第一通信设备可以确定数据信息2的覆盖增强等级与数据信息3的覆盖增强等级相同，且高于数据信息1和数据信息4的覆盖增强等级。另外，数据信息1的覆盖增强等级与数据信息4的覆盖增强等级相同。第一通信设备确定发送上述数据信息1-数据信息4的反馈信息的第一时隙发生碰撞，且第一通信设备能够复用的反馈信息的阈值为2。第一通信设备可以将覆盖增强等级最高的数据信息2和数据信息3的反馈信息复用于第一控制信息，并在第一时隙上发送该第一控制信息。第一通信设备可以将覆盖增强等级次高的数据信息3和数据信息4的反馈信息复用于第二控制信息，并在第二时隙上发送该第二控制信息。
方法2：将覆盖增强等级相同的至少一个数据信息对应的至少一个反馈信息，复用于控制信息。
第一通信设备可以将相同覆盖增强等级的一个或多个数据信息的反馈信息，复用于控制信息。如果上述一个或多个数据信息的反馈信息的数量小于前述阈值时，该控制信息的剩余资源可以被置为空闲资源。换句话说，第一通信设备仅在控制信息中复用相同覆盖增强等级的数据信息的反馈信息。
举例来说，第一通信设备接收到数据信息1、数据信息2和数据信息3。其中，数据信息1的覆盖增强等级为最高等级(如1级)，数据信息2的覆盖增强等级为最高等级(如1级)，数据信息3的覆盖增强等级为次高等级(如2级)。第一通信设备能够复用的反馈信息的阈值为2。因此，第一通信设备可以将数据信息1和数据信息2的反馈信息复用于第一控制信息中，并在第一时隙上发送该第一控制信息。第一通信设备可以将数据3的反馈信息承载于第二控制信息，并在第一时隙之后的一个时隙上发送该第二控制信息。
另外，如果第一通信设备待发送的属于同一覆盖增强等级的反馈信息的数量大于第一通信设备支持的数量阈值时，第一通信设备可以按照数据信息的接收顺序，发送对应的反馈信息。应理解，这里的至少一个数据信息的接收顺序可以是至少一个数据信息在时间域上的接收时间先后顺序。举例来说，第一通信设备按照时间的先后接收到数据信息1、数据信息2、数据信息3、数据信息4和数据信息5。其中，数据信息1的覆盖增强等级为最 高等级，数据信息2的覆盖增强等级为最高等级，数据信息3的覆盖增强等级为最高等级，数据信息4的覆盖增强等级为次高等级，数据信息5的覆盖增强等级为次高等级。第一通信设备能够复用的反馈信息的阈值为2。由于能够复用的反馈信息的阈值小于覆盖增强等级最高的数据信息的反馈信息的数量。因此，第一通信设备可以按照覆盖增强等级最高的数据信息的接收顺序，将数据信息1和数据信息2的反馈信息复用于第一控制信息，并在第一时隙上发送该第一控制信息。由于控制信息中包含的反馈信息所对应的数据信息的覆盖增强等级需相同，因此虽然在第二控制信息上可以复用两个反馈信息，但由于覆盖增强等级最高的数据信息的反馈信息仅剩一个(数据信息3的反馈信息)，所以第一通信设备仅在第二控制信息上承载数据信息2的反馈信息，并在第二时隙上发送该第二控制信息。第一通信设备可以将数据信息4和数据信息5的反馈信息复用于第三控制信息中，并在第三时隙上发送该第三控制信息。其中，第一时隙的时域位置在第二时隙的时域位置之前，第二时隙的时域位置在第三时隙的时域位置之前。
在一个示例中，第一通信设备可以根据接收到的同一数据信息的总数量，确定该数据信息的覆盖增强等级。举例来说，第一通信设备接收到了数据信息1的总数量为4，数据信息2的总数量为2，数据信息3的总数量为1。因此，第一通信设备可以确定数据信息1的覆盖增强等级高于数据信息2的覆盖增强等级，数据信息2的覆盖增强等级高于数据信息3的覆盖增强等级。
可选的，第一通信设备也可以根据数据信息中携带的标识信息确定覆盖增强等级。该标识信息可以表征该数据所属的业务。其中，第一通信设备可以预先存储标识信息与覆盖增强等级之间的对应关系。因此，第一通信设备在接收到数据信息时，可以根据该标识信息查找对应的覆盖增强等级。
参阅图4，第一通信设备接收到重复次数为2的数据信息1，重复次数为2的数据信息2，重复次数为1的数据信息3和重复次数为1的数据信息4。因此，第一通信设备可以确定数据信息1的覆盖增强等级与数据信息2的覆盖增强等级相同，且高于数据信息3和数据信息4的覆盖增强等级。另外，数据信息3的覆盖增强等级与数据信息4的覆盖增强等级相同。第一通信设备确定发送上述数据信息1-数据信息4的反馈信息的第一时隙发生碰撞，且第一通信设备能够复用的反馈信息的阈值为2。第一通信设备可以确定覆盖增强等级最高的数据信息的反馈信息的数量有2个(即数据信息1和数据信息2的反馈信息)等于上述阈值，因此可以将数据信息1和数据信息2的反馈信息复用于第一控制信息，并在第一时隙上发送该第一控制信息。第一通信设备可以确定覆盖增强等级次高的数据信息的反馈信息的数量有2个(即数据3和数据4的反馈信息)，因此可以将数据信息3和数据信息4的反馈信息复用于第二控制信息，并在第二时隙上发送该第二控制信息。
参阅图5，第一通信设备接收到重复次数为3的数据信息1，重复次数为2的数据信息2，重复次数为3的数据信息3以及重复次数为2的数据信息4。因此，第一通信设备可以确定数据信息1的覆盖增强等级与数据信息2的覆盖增强等级相同，且高于数据信息3和数据信息4的覆盖增强等级。另外，数据信息3的覆盖增强等级与数据信息4的覆盖增强等级相同。第一通信设备确定发送上述数据信息1-数据信息4的反馈信息的第一时隙发生碰撞，且第一通信设备能够复用的反馈信息的阈值为3。第一通信设备可以确定覆盖增强等级最高的数据信息的反馈信息的数量有2个(数据信息1和数据信息3的反馈信息)，因此可以将数据信息1和数据信息3的反馈信息复用于第一控制信息，并在第一时隙上进 行传输。虽然第一控制信息可以承载3个反馈信息，但由于控制信息包含的反馈信息所对应的覆盖增强等级需相同，因此第一通信设备可以将低于数据信息1和数据信息3的覆盖增强等级的数据信息2和数据信息4的反馈信息复用于第二控制信息，并在第二时隙上进行传输。
方法3：将具有第一覆盖增强等级的至少一个数据信息对应的至少一个反馈信息和具有至少一个第二覆盖增强等级的至少一个数据信息对应的至少一个反馈信息，复用于控制信息。
举例来说，第一通信设备接收到数据信息1、数据信息2和数据信息3。其中，数据信息1的覆盖增强等级为最高等级(如1级)，数据信息2的覆盖增强等级为次高等级(如2级)，数据信息3的覆盖增强等级为最低等级(如3级)。第一通信设备确定发送上述数据信息1-数据信息3的反馈信息的第一时隙发生了碰撞，且第一通信设备能够复用的反馈信息的阈值为2。第一通信设备可以确定覆盖增强等级最高的数据信息的反馈信息有1个(数据1的反馈信息)，但控制信息可以承载2个反馈信息，因此，第一通信设备可以将数据信息1的反馈信息和低于数据信息1的覆盖增强等级的数据信息2或数据信息3的反馈信息复用于控制信息。例如，第一通信设备可以将数据信息1的反馈信息和数据信息2的反馈信息复用于第一控制信息，并在第一时隙上传输。第一通信设备可以将数据信息3的反馈信息承载于第二控制信息，并在第一时隙之后的第二时隙上传输。或者，第一通信设备可以将数据信息1的反馈信息和数据信息3的反馈信息复用于第一控制信息，并在第一时隙上传输。第一通信设备可以将数据信息2的反馈信息承载于第二控制信息，并在第一时隙之后的第二时隙上传输。
本申请实施例中，覆盖增强等级x的数据信息，可以理解为具有覆盖增强等级x的数据信息。数据信息的反馈信息，可以理解为数据信息对应的反馈信息。这里的x可以是覆盖增强等级值。例如，覆盖增强等级1的数据信息，可以理解为具有覆盖增强等级1的数据信息。
在一个示例中，如果第一通信设备待发送的同一覆盖增强等级的数据信息的反馈信息的数量大于第一通信设备能够复用的反馈信息的阈值时，第一通信设备可以按照接收到数据信息的时间顺序，发送对应的反馈信息。举例来说，第一通信设备按照时间的先后接收到数据信息1、数据信息2、数据信息3、数据信息4和数据信息5。其中，数据信息1的覆盖增强等级为最高等级，数据信息2的覆盖增强等级为最高等级，数据信息3的覆盖增强等级为最高等级，数据信息4的覆盖增强等级为次高等级，数据信息5的覆盖增强等级为次高等级。第一通信设备确定发送上述数据信息1-数据信息5的反馈信息的第一时隙发生了碰撞，且第一通信设备能够复用的反馈信息的阈值为2。第一通信设备可以确定覆盖增强等级最高的数据信息的反馈信息有3个(数据信息1、数据信息2和数据信息3的反馈信息)。由于控制信息能够承载的反馈信息的阈值为2，因此第一通信设备可以按照数据信息的接收顺序，将数据信息1和数据信息2的反馈信息复用于第一控制信息，并在第一时隙上进行传输。此时覆盖增强等级最高的数据信息的反馈信息剩余1个(即数据信息3的反馈信息)，而控制信息可以承载2个反馈信息，因此第一通信设备可以将数据信息3的反馈信息和覆盖增强等级为次高等级的数据信息(即数据信息4和数据信息5)的反馈信息复用于第二控制信息，并在第二时隙上进行传输。第一通信设备可以按照数据信息的接收顺序，将数据信息3的反馈信息和数据信息4的反馈信息复用于第二控制信息，并在 第二时隙上进行传输。第一通信设备可以将数据信息5的反馈信息承载于第三控制信息，并在第三时隙上传输。
其中，第一通信设备可以根据接收到相同的数据信息的总数量，确定该数据信息的覆盖增强等级。举例来说，第一通信设备接收到了数据信息1的总数量为4，数据信息2的总数量为2，数据信息3的总数量为1。因此，第一通信设备可以确定数据信息1的覆盖增强等级高于数据信息2的覆盖增强等级，数据信息2的覆盖增强等级高于数据信息3的覆盖增强等级。第一通信设备接收到数据信息3的总数量为1，因此数据信息3可以是普通数据，即数据信息3可以不具有覆盖增强等级，或者数据信息3的覆盖增强等级是最低的。
可选的，第一通信设备也可以根据数据信息中携带的标识信息确定覆盖增强等级。该标识信息可以表征该数据所属的业务。其中，第一通信设备可以预先存储标识信息与覆盖增强等级之间的对应关系。因此，第一通信设备在接收到数据信息时，可以根据该标识信息查找对应的覆盖增强等级。
参阅图6，第一通信设备按照时间的先后顺序接收到重复次数为3的数据信息1，重复次数为2的数据信息2，重复次数为2的数据信息3以及重复次数为1的数据信息4。因此，第一通信设备可以确定数据信息1的覆盖增强等级最高，数据信息2的覆盖增强等级与数据信息3的覆盖增强等级次高，数据信息4的覆盖增强等级最低。第一通信设备确定发送上述数据信息1-数据信息4的反馈信息的第一时隙发生碰撞，且第一通信设备够复用的反馈信息的阈值为2。第一通信设备可以确定覆盖增强等级最高的数据信息的反馈信息有1个(即数据信息1的反馈信息)，但控制信息可以承载2个反馈信息。因此，第一通信设备可以将数据信息1的反馈信息以及覆盖增强等级为次高等级的数据信息(数据信息2或数据信息3)的反馈信息复用于第一控制信息。第一通信设备可以按照数据信息的接收顺序，将数据信息1的反馈信息和数据信息2的反馈信息复用于第一控制信息，并在第一时隙上进行传输。第一通信设备可以确定覆盖增强等级为次高等级的数据信息的反馈信息有1个，控制信息可以承载2个反馈信息，因此第一通信设备可以将数据信息3的反馈信息以及覆盖增强等级为最低等级的数据信息(数据信息4)的反馈信息复用于第二控制信息，并在第一时隙之后的第二时隙上进行传输。
参阅图7，第一通信设备按照时间的先后顺序接收到重复次数为3的数据信息1，重复次数为2的数据信息2，重复次数为3的数据信息3，重复次数为1的数据信息4以及重复次数为1的数据信息5。因此，第一通信设备可以确定数据信息1和数据信息3的覆盖增强等级最高，数据信息2的覆盖增强等级次高，数据信息4和数据信息5的覆盖增强等级最低。第一通信设备确定发送上述数据信息1-数据信息5的反馈信息的时域资源发生碰撞，且第一通信设备能够复用的反馈信息的阈值为2。第一通信设备可以确定覆盖增强等级最高的数据信息的反馈信息有2个(数据信息1和数据信息3的反馈信息)。由于控制信息可以承载2个反馈信息，因此，第一通信设备可以将数据信息1和数据信息3的反馈信息复用于第一控制信息，并在第一时隙上进行传输。第一通信设备可以确定覆盖增强等级次高的数据信息的反馈信息有1个(数据信息2的反馈信息)，但控制信息可以承载2个反馈信息，因此第一通信设备可以将数据信息2的反馈信息以及覆盖增强等级最低的数据信息的反馈信息(数据信息4的反馈信息或数据信息5的反馈信息)复用于第二控制信息，并在第一时隙之后的第二时隙上进行传输。第一通信设备可以按照数据信息的接收顺 序，将数据信息2和数据信息4的反馈信息复用于第二控制信息，并在第三控制信息上承载数据信息5的反馈信息，在第三时隙上进行传输。
方法4：在至少一个数据信息的覆盖增强等级均大于或等于所述预设门限时，按照至少一个数据信息的接收顺序，将至少一个数据信息的反馈信息复用于控制信息。
其中，第一通信设备在确定m个数据信息的覆盖增强等级大于或等于预设门限时，可以按照该m个数据信息的接收顺序，将m个数据信息的反馈信息复用于控制信息。这里的m可以是大于等于0的整数。第一通信设备在确定n个数据信息的覆盖增强等级小于预设门限时，可以按照前述方法1和/或方法2和/或方法3，将n个数据信息的反馈信息复用于控制信息。这里的n也可以是大于等于0的整数。应理解，前述预设门限可以是网络设备通过信令发送给第一通信设备的，或者也可以是协议预定的，本申请不做具体限定。
基于上述方案，当覆盖增强等级大于该门限时，表示覆盖增强级别都较高，因此可以按照时域顺序将反馈信息复用于控制信息。即优先级都较高的情形下，通过数据信息的接收顺序先后复用反馈信息，可以减少复杂度，保证高优先级的反馈信息依次得到反馈。
本申请实施例中，通过信令发送可以为通过无线资源控制(radio resource control，RRC)信令，介质访问控制(media access control，MAC)信令或物理层信令中的至少一种信令发送。
参阅图8，第一通信设备按照时间的先后顺序接收到了重复次数为2的数据信息1，重复次数为3的数据信息2，重复次数为3的数据信息3，重复次数为2的数据信息4、重复次数为1的数据信息5。其中，第一通信设备确定数据信息1、数据信息2和数据信息3的覆盖增强等级最高且高于预设门限，数据信息4的覆盖增强等级次高且低于预设门限，数据信息5的覆盖增强等级最低且低于预设门限。第一通信设备确定发送上述数据信息1-数据信息5的反馈信息在第一时隙发生碰撞，且第一通信设备能够复用的反馈信息的阈值为2。由于数据信息1、数据信息2和数据信息3的覆盖增强等级高于预设门限，因此第一通设备可以按照数据信息的接收顺序，将数据信息1-数据信息3的反馈信息复用于第一控制信息。由于控制信息可以承载2个反馈信息，因此第一通信设备将数据信息1和数据信息2的反馈信息复用于第一控制信息，并在第一时隙上进行传输。第一通信设备将数据信息3的反馈信息承载于第二控制信息，并在第二时隙上进行传输。由于数据信息4和数据信息5的反馈信息低于预设门限，因此第一通信设备可以按照覆盖增强等级由高到低的顺序传输数据信息4和数据信息5的反馈信息。例如，第一通信设备按照上述方法1传输数据信息4和数据信息5的反馈信息。由于数据信息4和数据信息5的覆盖增强等级不同，因此第一通信设备可以将数据信息4的反馈信息承载于第三控制信息，并在第三时隙上进行传输，将数据信息5的反馈信息承载于第四控制信息，并在第四时隙上进行传输。
本申请实施例中，在第x时隙发生碰撞，可以理解为，在该第x时隙，待传输的信息超出能够传输的信息，或者待传输的信息超出能够复用的信息。这里的待传输的信息可以包含反馈信息。举例来说，在第一时隙发生碰撞，可以理解为，在该第一时隙上待传输的信息数量超出能够传输的信息数量，或者也可以理解为在第一时隙上待传输的信息数量超出能够复用的信息数量。在第一时隙发生碰撞，还可以理解为，在该第一时隙上待传输的信息功率超出能够传输的最大功率，或者也可以理解为在第一时隙上待传输的信息功率超出能够复用的最大功率。能够服用的信息，可以理解为能够同时传输的用于HARQ反馈的比特数。
可选的，如图9所示，第一通信设备可以按照上述方法2传输数据信息4和数据信息5的反馈信息。例如，虽然数据信息4和数据信息5的覆盖增强等级不同，但控制信息可以承载2个反馈信息，因此第一通信设备可以将数据信息4和数据信息5的反馈信息复用于第三控制信息，并在第三时隙上进行传输。
可选的，第一通信设备可以按照上述方法2传输数据信息3、数据信息4和数据信息5的反馈信息。例如，虽然数据信息3和数据信息4的覆盖增强等级不同，但控制信息可以承载2个反馈信息，因此第一通信设备可以将数据信息3和数据信息4的反馈信息复用于第二控制信息，并在第二时隙上进行传输。第一通信设备可以将数据信息5的反馈信息承载于第三控制信息，并在第三时隙上进行传输。
可选的，第一通信设备按照时间的先后顺序接收到了重复次数为2的数据信息1，重复次数为3的数据信息2，和重复次数为3的数据信息3。其中，第一通信设备确定数据信息1，数据信息2和数据信息3的覆盖增强等级都高于预设门限。第一通信设备确定发送上述数据信息1-数据信息3的反馈信息在第一时隙发生碰撞，且第一通信设备能够复用的反馈信息的阈值为3。由于数据信息1，数据信息2和数据信息3的覆盖增强等级高于预设门限，因此第一通设备可以按照数据信息的接收顺序，将数据信息1-数据信息3的反馈信息复用于第一控制信息。由于控制信息可以承载3个反馈信息，因此第一通信设备将数据信息1，数据信息2和数据信息3的反馈信息复用于第一控制信息，并在第一时隙上进行传输。
基于上述方案，当覆盖增强等级小于该门限时，表示覆盖增强级别不是很高，因此可以区分覆盖增强等级的高低分别对待，所以可以优先反馈覆盖增强等级高的数据信息对应的反馈信息，再反馈覆盖增强等级低的数据信息对应的反馈信息。
本申请实施例中，数据信息可以理解为传输块。另外需要说明的是，上述方法1-方法4中任一种的反馈信息的复用方法可以是预先设置的，或者也可以是协议规定的，或者也可以是网络设备通过RRC信令发送给第一终端设备的，本申请不做限定。
步骤203：通信设备在第一控制信道或第一数据信道发送控制信息。
其中，通信设备可以在第一时隙以及第一时隙之后的至少一个时隙中的第一控制信道或者第一数据信道发送该控制信息。该控制信息可以被承载于第一控制信道或第一数据信道。
或者，通信设备可以在第一时隙中的第一控制信道或者第一数据信道发送该控制信息。该控制信息可以被承载于第一控制信道或第一数据信道。
