Description

一种通信方法及设备 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及设备。
背景技术
对于某些业务，其两次业务之间的间隔较长，而且其通信数据包较小。为了达到节能，减少信令开销的目的，LTE release-16决定标准化在预先定义好的资源上进行传输的机制，也就是不需要动态的下行链路控制信息(downlink control information，DCI)调度的通信，因此也叫做免调度传输。上行免调度传输的过程为：当终端设备有上行数据需要发送时，不需要网络设备对终端设备进行动态的上行调度，终端设备在预先配置的传输资源上按照预先规定的发送方式进行上行传输。
目前，终端设备在预配置的上行链路资源(preconfigured uplink resource transmission，PUR)上进行上行传输后，网络设备可以在PDCCH中反馈ACK/NACK信息，其中，ACK表示预配置资源传输成功，NACK表示预配置资源传输失败。而在网络设备反馈ACK/NACK信息后，终端设备需要在一定的时间内继续监测是否有调度下行数据的DCI，通过该DCI来接收下行数据。可见，终端设备在下行调度过程中需要盲检调度下行数据的DCI，这样增加了终端设备的功耗。
发明内容
本申请实施例提供了一种通信方法及设备，用于解决现有技术中终端设备在下行调度过程中功耗浪费的问题。
第一方面，本申请实施例提供了一种通信方法，包括：第一设备确定第一控制信息，所述第一控制信息包括第一指示信息以及第二指示信息，其中，所述第一指示信息用于指示预配置资源传输的状态，所述状态包括成功传输或未成功传输或调度重传或在预配置资源中重传；所述第二指示信息用于指示所述第一设备是否传输第一信息，所述第一信息包括高层数据和/或预配置上行链路资源的重配信息；所述第一设备向第二设备发送所述第一控制信息。本申请实施例中，第一设备在向第二设备反馈预配置资源传输的状态时，指示第二设备是否传输高层数据和/或PUR重配信息，从而第二设备在接收预配置资源传输的状态时可以确定是否接收高层数据和/或PUR重配信息。相比于现有技术中第二设备盲检调度下行数据的DCI的方式，本申请实施例中第一设备在没有传输高层数据和/或PUR重配信息时可以通过第一控制信息通知第二设备，从而第二设备可以不用监测调度高层数据的DCI，使得第二设备可以减少盲检的次数，进而可以节省第二设备的功耗。

在一种可能的设计中，所述第一控制信息的第一字段可以用于指示所述第二指示信息。上述设计中，通过复用第一控制信息中的一个字段来指示第二指示信息，可以避免增加控制信息开销，进而可以避免降低频谱效率，以及可以提升系统资源利用率，避免增加用户功耗。
在一种可能的设计中，所述第一控制信息为格式6-1A或格式6-1B的控制信息，所述第一字段可以为所述第一控制信息的资源块分配字段。上述设计中，通过资源块分配字段来指示第二指示信息，可以避免在第一控制信息中增加比特，从而可以有效的避免增加控制信息开销，进而可以避免降低频谱效率，以及可以提升系统资源利用率，避免增加用户功耗。

具体实施方式
下面将结合附图对本申请实施例作进一步地详细描述。
本申请提供的通信方法可以应用于各类通信系统中，例如，可以是物联网(internet of things，IoT)、窄带物联网(narrow band internet of things，NB-IoT)、长期演进(long term evolution，LTE)，也可以是第五代(5G)通信系统，还可以是LTE与5G混合架构、也可以是5G新无线(newradio，NR)系统、全球移动通信系统(global system for mobile communication，GSM)，移动通信系统(universal mobile telecommunications system，UMTS)，码分多址接入(code division multiple access，CDMA)系统，以及未来通信发展中出现的新的通信系统等。只要通信系统中存在一个实体可以发送用于调度传输块的控制信息，以及发送、接收传输块，另一个实体可以接收用于调度传输块的控制信息，以及接收、发送传输块，均可以采用本申请实施例提供的通信方法。
本申请实施例中涉及的终端设备，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端设备也可以是连接到无线调制解调器的其他处理设备。终端设备可以通过无线接入网(radio access network，RAN)与一个或多个核心网进行通信。终端设备也可以称为无线终端、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(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device)、或用户装备(user equipment)等等。终端设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，终端设备还可以是个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等，但本申请实施例不限于此。
本申请实施例中所涉及的网络设备，可以用于将收到的空中帧与网络协议(internet protocol，IP)分组进行相互转换，作为终端设备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以包括IP网络等。网络设备还可以协调对空中接口的属性管理。例如，网络设备可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的基站(NodeB)，还可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB)，还可以是新无线控制器(new radio controller，NR controller)，可以是5G系统中的gNode B(gNB)，可以是集中式网元(centralized unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站，可以是中继(relay)，可以是分布式网元(distributed unit)，可以是接收点(transmission reception point，TRP)或传输点(transmission point，TP)或者任何其它无线接入设备，但本申请实施例不限于此。网络设备可以覆盖1个或多个小区。
参阅图1所示，为本申请实施例提供的一种通信系统，该通信系统包括网络设备和六个终端设备，即UE1～UE6。在该通信系统中，UE1～UE6可以发送上行数据给网络设备，网络设备可以接收UE1～UE6发送的上行数据。此外，UE4～UE6也可以组成一个子通信系统。网络设备可以发送下行信息给UE1、UE2、UE3、UE5，UE5可以基于设备到设备(device-to-device，D2D)技术发送下行信息给UE4、UE6。图1仅是一种示意图，并不对通信系统的类型，以及通信系统内包括的设备的数量、类型等进行具体限定。
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。
在通信系统中，UE可能处于三种状态：空闲(idle)态、非激活态(inactive)和连接态(connected)。connected态UE可以通过基站动态调度与基站进行通信，传输数据，而对于idle态UE而言，其不能通过基站动态调度来传输数据，需要首先进行随机接入，建立RRC连接以后才能够进行数据的传输，或者是在随机接入过程中的消息3中携带少量的上行数据。Inactive态可以看做是这两种状态的一种中间状态，UE和核心网保留了connected态时无线资源控制(radio resource control，RRC)消息的上下文，因此相比于idle态可以以更快速度的进入connected态。根据目前LTE协议的规定，在UE由RRC connected 态转入idle态的时候，RRC的配置消息是不保留的，但是由connected态转为inactive态的时候是保留RRC消息的上下文的。
对于某些业务，为了降低资源开销，降低数据传输时延和节能，如图2所示，可在预先定义好的资源上传输业务，也就是不需要动态的下行控制信息(downlink control information，DCI)调度，用户在预先配置的资源上传输信号。这种传输叫做配置调度传输，也叫预配置资源传输或预配置资源免调度传输或免调度传输。特别地，预配置的资源可以是预配置的上行链路资源。上行免调度传输或预配置上行资源传输(preconfigured uplink resource transmission，PUR)的过程为：当终端设备有上行数据需要发送时，不需要网络设备对终端设备进行动态的上行调度，终端设备在预先配置的传输资源上按照预先规定的发送方式进行上行传输。
目前，终端设备在预配置的上行链路资源(preconfigured uplink resource transmission，PUR)上进行上行传输后，网络设备可以在PDCCH中反馈ACK/NACK信息，其中，ACK表示预配置资源传输成功，NACK表示预配置资源传输失败。而在网络设备反馈ACK/NACK信息后，终端设备需要在一定的时间内继续监测是否有调度下行数据的DCI，通过该DCI来接收下行数据。可见，终端设备在下行调度过程中需要盲检调度下行数据的DCI，这样增加了终端设备的功耗。
基于此本申请实施例提供一种通信方法及设备，用于解决现有技术中终端设备在下行调度过程中功耗浪费的问题。其中，方法和装置是基于同一发明构思的，由于方法及设备解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例中所涉及的多个，是指两个或两个以上。
需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
参见图3，为本申请提供的一种通信方法的流程图。该方法可以应用于图1所示通信系统中的第二设备，该方法包括：
S301，第一设备确定第一控制信息，所述第一控制信息包括第一指示信息以及第二指示信息，其中，所述第一指示信息用于指示预配置资源传输的状态，所述状态包括成功传输或未成功传输或调度重传或在预配置资源中重传；所述第二指示信息用于指示所述第一设备是否传输第一信息，所述第一信息包括高层数据和/或PUR重配信息。
其中，“高层数据”也可以称为“下行数据”，或者“数据”，或者也可以称为“下行高层数据”。可以理解，当第二设备向第一设备通过预配置传输方式成功传输信息以后，第一设备与第二设备会有相应的交互信息，例如高层ACK等。
具体实施中，第一控制信息包括第一指示信息，这种情况下，第一控制信息可以不包括第二指示信息。或者，第一控制信息包括第二指示信息，这种情况下，第一控制信息可以不包括第一指示信息。或者，第一控制信息也可以在第一指示信息指示成功传输(即ACK)时包括高层数据和/或PUR重配信息，在第一指示信息指示未成功传输或调度重传或在预配置上行链路资源中重传(即NACK)时包括PUR重配信息。
需要说明的是，预配置上行链路资源(preconfigured uplink resource,PUR)仅是一种示例性命名，其实质是网络设备通过配置该资源，第二设备可以在不需要第一设备动态调度或下行控制信息调度的情况下在该资源上进行上行信息的传输，该资源也可以命名为其他名称，如配置授权资源，应理解，若该配置授权资源也可以实现本申请实施例中的预配 置上行资源所实现的功能，也可以将配置授权资源理解为本申请实施例中的预配置上行资源。为了描述方便，本申请实施例中将该资源统一称为预配置上行链路资源。
预配置资源传输，可以指第二设备在预配置上行链路资源按照预先规定的参数进行数据传输。本申请实施例中“预配置资源传输”也可以称为“预配置传输方式”、“免调度传输”、“预配置资源传输”、“预配置资源免调度传输”等，应理解，本申请实施例中“预配置资源传输”仅是一种示例性说明，在实际应用中，也可以将“预配置资源传输”命名为其他名称，若该其他名称也可以实现本申请实施中“预配置资源传输”的功能，都可以理解为按照预配置资源传输的方式进行上行信号传输。为了描述方便，本申请实施例中将该传输方式统一称为预配置资源传输。
预配置资源重传可以指，在预配置上行链路资源中或在部分预配置上行链路资源中进行重传，即不需要动态调度信息(如DCI)调度，而是通过预配置上行链路资源进行重传，但是相应的预配置资源的配置信息可以通过动态调度信息进行重配或更新。
调度重传是指第二设备根据第一设备的动态调度信息(如DCI)的调度信息进行重传。
其中，预配置上行链路资源的重配信息可以但不限于包括下列信息的一个或多个：时间(定时)提前、功率控制信息、重复次数、调制与编码策略(modulation and coding scheme，MCS)、传输块大小(transport block size，TBS)等。
示例性的，第一控制信息可以为LTE eMTC系统中的下行控制信息，NR系统的下行控制信息等等，这里不做具体限定。为了方便描述，下面以第一控制信息为下行控制信息(downlink control information，DCI)为例。
具体实施中，所述第二指示信息可以包括：用于指示在所述第一控制信息调度的物理下行共享信道(physical downlink shared channel，PDSCH)中是否承载所述第一信息的指示信息。
需要说明的是，本申请实施例中，“所述第一控制信息调度所述第一信息”、“第一控制信息调度PDSCH”、“在所述第一控制信息调度的PDSCH中承载所述第一信息”、“有第一信息”均可以理解为第一控制信息调度的PDSCH中包括第一信息。
或者，所述第二指示信息也可以包括：用于指示所述第二设备是否检测第二控制信息的指示信息，所述第二控制信息用于调度所述第一信息。
需要说明的是，本申请实施例中，“所述第二设备检测第二控制信息”、“所述第二设备监测第一搜索空间，所述第一搜索空间为承载或传输所述第二控制信息的搜索空间”均可以理解为第二设备需要监测第二控制信息。
或者，所述第二指示信息也可以包括：用于指示所述第一控制信息中是否包括预配置上行链路资源重配信息的指示信息。
或者，所述第二指示信息也可以包括：用于指示所述第二设备在所述第一控制信息中是否包括预配置上行链路资源重配信息的指示信息，以及用于指示所述第二设备是否检测第三控制信息的指示信息，所述第三控制信息用于调度所述高层数据。
需要说明的是，本申请实施例中，“所述第二设备检测第三控制信息”、“所述第二设备监测第二搜索空间，所述第二搜索空间为承载或传输所述第三控制信息的搜索空间”均可以理解为第二设备需要监测第三控制信息。
其中，第一设备可以为网络设备，第二设备可以为终端设备。或者，第二设备可以为网络设备，第一设备可以为终端设备。或者，第一设备可以为具有发送能力的设备，第二 设备可以为具有接收能力的设备。
S302，所述第一设备向所述第二设备发送所述第一控制信息。对应的，第二设备基于第二指示信息确定是否接收第一信息。
具体实施中，第一控制信息可以为一个或多个控制信息，若第一控制信息为一个控制信息，则该控制信息中包括第一指示信息以及第二指示信息这两个指示信息。若第一控制信息为多个控制信息，则其中一个控制信息包括第一指示信息，另一个控制信息包括第二指示信息，所述多个控制信息可以一起发送，从而第二设备可以一起接收所述多个控制信息，而不需要进行额外检测。
S303，所述第二设备在确定所述第二指示信息指示所述第一设备传输所述第一信息之后，根据所述第二指示信息接收所述第一信息。
本申请实施例中，第一设备在向第二设备反馈预配置资源传输的状态时，指示第二设备是否传输高层数据和/或预配置上行链路资源重配信息，从而第二设备在接收预配置资源传输的状态时可以确定是否接收高层数据和/或预配置上行链路资源重配信息。相比于现有技术中第二设备盲检调度下行数据的DCI的方式，本申请实施例中第一设备在没有传输高层数据和/或预配置上行链路资源重配信息时可以通过第一控制信息通知第二设备，从而第二设备可以不用监测调度高层数据的DCI，使得第二设备可以减少盲检的次数，进而可以节省第二设备的功耗。
为了方便描述，本申请实施例中，将“所述第一控制信息调度的PDSCH中承载第一信息”、“第一控制信息调度PDSCH”、“第一控制信息指示检测第二控制信息”、“第一控制信息指示监测第一搜索空间”统一称为“调度第一信息”。将“所述第一控制信息调度的PDSCH中承载高层数据”、““第一控制信息指示检测第三控制信息”、“第一控制信息指示监测第二搜索空间”、“第一控制信息传输高层数据”等均称为“有高层数据”。将“所述第一控制信息调度的PDSCH中承载PUR重配信息”、“第一控制信息中包括PUR重配信息”等均称为“包括PUR重配信息”。
在具体实施中，第一设备可以但不限于通过如下两种方式在第一控制信息中指示第二指示信息：
方式一，所述第一控制信息可以通过一个字段来指示第二指示信息，如第一字段用于指示所述第二指示信息。进一步的，第一字段指示第二指示信息时可以认为预配置资源传输成功传输，也就是，第一字段可以指示预配置资源传输成功传输以及第二指示信息。
一种实例性说明中，所述第一控制信息可以为格式(format)6-1A或format6-1B的控制信息，所述第一字段可以为所述第一控制信息的资源块分配(resource block assignment)字段。例如，可以在第一字段中比特全部取值为1时，所述第二指示信息指示所述第一设备未调度PDSCH，还可以指示成功传输。所述第一字段中比特未全部取值为1，所述第二指示信息可以指示所述第一设备调度PDSCH，还可以指示成功传输(或成功接收)。以第一信息包括高层数据为例，如表1所示。本申请实施例中，“成功传输”也可称为“成功接收”。

另一种示例性说明中，所述第一控制信息为format N0的控制信息，所述第一字段可以为所述第一控制信息的子载波指示(subcarrier indication)字段或调制编码方案(modulation and coding scheme，MCS)字段。subcarrier indication字段、MCS字段的冗余状态，可以参见表2所示。例如，3.75kHz子载波间隔时，Subcarrier indication字段的取值为48-63中的某个值时表示成功接收且没有调度PDSCH。再例如：15kHz子载波间隔时，Subcarrier indication字段的取值为19-63中的某个值时表示成功接收且没有调度PDSCH。再例如：对于single tone，MCS字段的取值为11-15中的某个值时表示成功接收且没有调度PDSCH。再例如：对于multi-tone，MCS字段的取值为14或15表示成功接收且没有调度PDSCH。

方式二，所述第一控制信息可以通过两个字段来指示第二指示信息，如第二字段和第三字段用于指示所述第二指示信息。其中，当第一控制信息通过第二字段和第三字段指示第二指示信息时可以认为PUR成功传输，也就是，第二字段和第三字段指示预配置资源传输成功传输以及第二指示信息。
一种示例性说明中，所述第二字段可以为所述第一控制信息的resource block assignment字段。若所述第二字段中比特全部设置为1，所述第三字段可以用于指示所述第二指示信息。
其中，第三字段可以通过两个取值状态来指示是否传输第一信息。如，第三字段的一个状态指示调度PDSCH，还可以指示成功传输，第三字段的另一个状态指示没有调度PDSCH，还可以指示成功传输，如表5-1所示。
表5-1
第三字段 指示内容
一个状态 成功传输，没有调度PDSCH
另一个状态 成功传输，有调度PDSCH

另一种示例性说明中，第二字段可以通过状态一和状态二分别指示是否有高层数据，第三字段可以通过状态三和状态四分别指示是否包括预配置上行链路资源重配信息。例如，第二字段为状态一且第三字段为状态三，则指示没有高层数据，且没有包括预配置上行链路资源重配信息。第二字段为状态一且第三字段为状态四，则指示有高层数据，且没有包括预配置上行链路资源重配信息。第二字段为状态二且第三字段为状态三，则指示没有高层数据，且包括预配置上行链路资源重配信息。第二字段为状态二且第三字段为状态四，则指示有高层数据，且包括预配置上行链路资源重配信息。如表7-1所示。

下面以第二字段为resource block assignment，第三字段为新传指示(new data indicator，NDI)为例，若resource block assignment中比特全部设置为1则指示没有高层数据，若resource block assignment中比特未全部设置为1则指示有高层数据。若NDI为第五状态则指示包括预配置上行链路资源重配信息，若NDI为第六状态则指示未包括预配置上行链路资源重配信息，如表7-2所示，或者表8所示。

应理解，表7以及表8仅是一种示例性说明，并不对第二字段的类型、第二字段的状态、第三字段的类型、第三字段的状态、指示的内容、状态与指示内容的对应关系等进行具体限定。
作为一种可能的实现方式，第一控制信息为format N0的控制信息，所述第二字段可以为所述第一控制信息的subcarrier indication字段或MCS字段。第三字段可以为除第二字段以外的其他字段，具体不做限定。
作为另一种可能的实现方式，第一控制信息为formatN1的控制信息，且所述第一控制信息用于指示调度授权，所述第二字段可以为所述第一控制信息的MCS字段。第三字段可以为除第二字段以外的其他字段，具体不做限定。
作为又一种可能的实现方式，第一控制信息为formatN1的控制信息，且所述第一控制信息用于指示物理控制信道指令，所述第二字段可以为所述第一控制信息的物理随机接入信道重复的起始数量字段、或者物理随机接入信道的子载波指示字段、或者保留字段。第三字段可以为除第二字段以外的其他字段，具体不做限定。
在一些实施例中，第一设备可以但不限于通过如下任一方式在第一控制信息中指示第一指示信息：
方式一，可以采用第一控制信息的上下行区分标志位，如Flag format 6-0A/format 6-1A differentiation、或者Flag for format N0/format N1differentiation。由于预配置资源传输不需要动态DCI进行调度，当预配置资源传输成功传输时，一般反馈的是ACK、下行高层数据和预配置上行链路资源重配信息中一种或多种，因此可以使用调度下行数据的DCI来进行调度。当预配置资源传输传输失败后，反馈的是NACK和/或重传的调度信息，因此使用调度上行数据的DCI来进行调度。因此可以复用下行控制信息中的区分标志位来作为ACK/NACK的指示，即当标志位为0时表示NACK，标志位为1时表示ACK，这样可以节省DCI开销，增加DCI使用的灵活性。以Flag format 6-0A/format 6-1A differentiation为例，上下行区分标志位指示第一指示信息的方式可以如表9所示。
表9
Figure PCTCN2019080656-appb-000014
应理解，表9仅是一种示例性说明，并不对字段的类型、字段的状态、状态与指示内容的对应关系等进行具体限定。
进一步的，若第一指示信息指示预配置资源传输未成功传输时，第一设备还可以通过第一控制信息指示第三信息，第三信息用于指示第二设备执行以下动作中的一种或多种：发起随机接入、提前数据传输(early data transmission，EDT)、NACK、调度重传、预配置资源重传、预配置资源重传且配置更新，例如，可以如表10所示。其中，调度重传可以指通过动态DCI进行调度重传。通过这种方式可以进一步使用第一控制信息的冗余比特信息来指示第二设备回退(fallback)(即指示第二设备发起随机接入或者EDT)或预配置资源重传或预配置资源重配等，从而可以提高传输成功概率，提升DCI使用的灵活性。
表10

应理解，表10仅是一种示例性说明，并不对第一个字段的类型、第一个字段的状态、第二个字段的类型、第二个字段的状态、指示的内容、状态与指示内容的对应关系等进行具体限定。
方式二，若第一控制信息为针对覆盖增强模式A或覆盖增强等级0或覆盖增强等级1用户的控制信息(如format 6-1A、format 6-0A)，可以通过resource block assignment字段指示第一指示信息。例如，可以通过将调度下行数据的DCI(format 6-1A)的resource block assignment字段的比特全部设置为1指示成功传输，通过将调度上行数据中的DCI(format6-0A)的resource block assignment字段的比特全部设置为1指示未成功传输。
若第一控制信息为针对覆盖增强模式B或覆盖增强等级2或覆盖增强等级3用户的控 制信息(如format 6-1B、format 6-0B)，可以通过将调度下行数据的的DCI(format 6-1B)的resource block assignment字段的比特全部设置为1指示成功传输，通过将调度上行数据的DCI(format 6-0A)的MCS字段的比特全部设置为1指示未成功传输。如表11所示。
表11
Figure PCTCN2019080656-appb-000016
应理解，表11仅是一种示例性说明，并不对字段的类型、字段的状态、状态与指示内容的对应关系等进行具体限定。
上述方式二通过使用DCI中的冗余状态来指示是否正确传输，可以节省DCI开销，增加DCI使用的灵活性。
方式三，若第一控制信息为针对覆盖增强模式A或覆盖增强等级0或覆盖增强等级1用户的控制信息(如format 6-1A、format 6-0A)，可以通过resource block assignment字段指示第一指示信息。例如，调度上行数据的DCI中resource block assignment字段所有比特被设置为1表示成功接收，反之表示未成功接收。若第一控制信息为针对覆盖增强模式B或覆盖增强等级2或覆盖增强等级3用户的控制信息(如format 6-1B、format 6-0B)，可以通过MCS字段指示第一指示信息。例如，调度上行数据中的DCI中MCS字段所有比特被设置为1表示成功接收，反之表示未成功接收，如表12所示。该实现方式中，可以适用上行DCI反馈ACK/NACK。该方法使用DCI中的冗余状态表征是否正确传输，可以节省DCI开销，增加DCI使用的灵活性。
表12

Figure PCTCN2019080656-appb-000018
应理解，表12仅是一种示例性说明，并不对字段的类型、字段的状态、状态与指示内容的对应关系等进行具体限定。
方式四，可以通过第一控制信息的一个比特来指示第一指示信息，如可以用1指示成功传输，用0指示未成功传输。当然也可以用0指示成功传输，用1指示未成功传输。如表13所示。该比特可以是第一控制信息中新增的一个比特，也可以是第一控制信息中原有的一个比特。
表13

第一取值 成功接收
第二取值 未成功接收
方式五，可以通过两个字段来指示第一指示信息。示例性的，若第一控制信息为针对覆盖增强模式A或覆盖增强等级0或覆盖增强等级1用户的控制信息(如format 6-1A、format 6-0A)，第一个字段可以为resource block assignment字段(或NDI字段)，第二个字段可以为MCS域中的一个比特来指示第一指示信息。例如，调度上行数据的DCI中resource block assignment字段所有比特被设置为1且MCS域中的该比特为1，指示成功传输(ACK)。调度上行数据的DCI中resource block assignment字段中所有比特被设置为1且MCS域中的该比特为0表示未成功传输且仅为NACK，以触发第二设备进行fallback或PUR重传。Resource block assignment字段为其他状态可以表示未成功传输且调度重传。若第一控制信息为针对覆盖增强模式B或覆盖增强等级2或覆盖增强等级3用户的控制信息(如format6-1B、format 6-0B)，第一个字段可以为MCS字段(或NDI字段)，第二个字段可以为重复次数(repetition number)字段中的一个比特来指示第一指示信息。例如，调度上行数据的DCI中MCS字段所有比特被设置为1且重复次数字段中的该比特为1，指示成功传输(ACK)。调度上行数据的DCI中MCS字段中所有比特被设置为1且repetition number字段中的该比特为0表示未成功传输且仅为NACK，以触发第二设备进行fallback或PUR重传。MCS字段为其他状态可以表示未成功传输且调度重传。该实现方式中，仅适用上行DCI反馈ACK/NACK。该方法使用DCI中的冗余状态指示是否正确传输，可以节省DCI开销，增加DCI使用的灵活性。如表14所示。
表14

应理解，表14仅是一种示例性说明，并不对第一个字段的类型、第一个字段的状态、第二个字段的类型、第二个字段的状态、指示的内容、状态与指示内容的对应关系等进行具体限定。
具体实施中，第二个字段还可以扩展为多个比特，用于指示发起随机接入、EDT、ACK、预配置资源重传、预配置资源重传且配置更新中的一种或多种。例如，如表15所示。

作为一种可能的实施方式，上述几种示例性说明中，所述第一控制信息的循环冗余校 验码(cyclic redundancy check，CRC)可以由第一加扰码进行加扰，其中，第一加扰码可以为系统信息无线网络临时标识(system information radio network temporary identifier，SI-RNTI)。
在一些实施例中，本申请实施例中，第一控制信息中还可以包括HARQ-ACK(或PUCCH)的配置信息。该配置信息可以但不限于包括以下信息的一种或多种：时频资源信息(该时频资源可以是通过两级配置、高层配置等方式配置的)，反馈时间(也就是延时)，功率控制信息，重复次数等。其中，时频资源信息可以是具体的资源配置信息，也可以为资源索引等等。
