附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本申请的一个示例性实施例提供的通信系统的示意图；
图2是根据本申请的一示例性实施例示出的控制信息的传输方法的流程图；
图3是根据本申请的一示例性实施例示出的控制信息的传输方法的流程图；
图4是根据本申请的一示例性实施例示出的控制信息的映射表；

图8是根据本申请的一示例性实施例示出的接入网设备(基站)的框图。
具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的通信系统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，随着通信系统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。
图1是本公开一示例性实施例示出的通信系统的系统结构图。如图1所示，该通信系统可以包括：接入网12和终端13。
接入网12中包括若干个接入网设备120。接入网设备120与核心网设备110之间通过某种接口技术互相通信，例如长期演进(Long-Term Evolution，LTE)系统中的S1接口，新空口(New Radio，NR)系统中的NG接口。接入网设备120可以是基站，所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称的描述可能会变化。虽然本公开实施例中采用“基站”来进行举例说明，但该基站可以理解为各个通信系统中用于提供用户接入功能的接入网设备。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端(英文：terminal device)等等。为方便描述，上面提到的设备统称为终端。接入网设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
可选地，上述通信系统对传输时延的要求较高，比如上行通信系统支持eURLLC业务。在某些实施例中，该eURLLC业务要求端到端的时延要求达到0.5ms。
下行控制信道(PDCCH)承载基站发送给UE的下行控制信息(DCI，Downlink Control information)。目前DCI含有八种DCI格式(format)：DCI格 式0_0、DCI格式0_1、DCI格式1_0、DCI格式1_1、DCI格式2_0、DCI格式2_1、DCI格式2_2、DCI格式2_3。
PDCCH承载的DCI的作用有：调度PUSCH，调度PDSCH，指示SFI(Slot Format Indicator)，指示PI(Pre-emption Indicator)，功控命令，具体的DCI格式以及携带的信息见下述：
在详细介绍下行控制信道前，需要对下行信道的一些基本概念进行定义，具体包括控制信道单元(CCE，Control-channel Element)/搜索空间(Search Space)/资源单元组(REG，Resource-Element Group)/资源单元组束(REG bundle)和控制资源集合(CORESET，control-resource Set)等。CCE是构成PDCCH的基本单位，占用频域资源上6个REG。一个给定的PDCCH可由一个，2个，4个，8个，和16个CCE构成，其具体取值由DCI载荷大小(DCI payload size)和所需的编码速率决定。构成PDCCH的CCE数量被称为聚合等级。基站可根据实际传输的无线信道状态对PDCCH的聚合等级进行调整，实现链路自适应传输。
基站实际发送的PDCCH的聚合等级随时间可变，而且由于没有相关信令告知UE，UE需要在不同聚合等级下盲检PDCCH，其中，待盲检的PDCCH称为候选PDCCH。UE会在搜索空间内对所有候选的PDCCH进行译码，如果CRC校验通过，则认为所译码的PDCCH的内容对所述UE有效，并利用译码所获得的信息(如掉调度指示，时隙格式指示/功率控制命令等)进行后续操作。为了降低UE盲检的复杂度，需要限制盲检测CCE的集合。候选PDCCH的起始CCE序号需要能够被候选PDCCH的CCE数整除。
UE在有限的CCE位置上检测PDCCH，从而避免了盲检测复杂度的增加，然而这样做并不足够，在NR中为了更好地控制盲检测的复杂度，控制信息格式/聚合等级，聚合等级对应的候选控制信道的数量，以及搜索空间在时域上的检测周期都可通过高层参数进行配置，基于这些配置信息可以灵活控制盲检测的复杂度。简单的概括为，在候选的CCE集合内，并不是每个DCI格式都需要盲检。
图2示出了本申请一个示意性实施例提供的控制信息的传输方法的流程图。该反馈方法可以由图1所示的通信系统来执行，该方法包括：
步骤201，终端在PUSCH的时隙n上向基站发送上行数据；
步骤202，基站在PUSCH的时隙n上接收终端发送的上行数据；
步骤203，基站生成上行数据的反馈信息，该反馈信息包括ACK或NACK；
当上行数据接收成功时，基站生成ACK；当未能接收到上行数据，或，接收到上行数据且该上行数据的CRC失败时，基站生成NACK。
步骤204，基站在PDSCH的时隙n+k的指定频域位置上向终端发送控制信息；
可选地，该控制信息包括：ACK或NACK。在其他实施例中，该控制信息也可以用于携带其他信息，比如，PUSCH的信道质量信息、终端的功率控制信息等。
可选地，k小于阈值。
步骤205，终端在PDSCH的时隙n+k上的指定频域位置接收基站发送的控制信息；
可选地，当控制信息包括上行数据的NACK时，终端重传上行数据。
综上所述，本实施例提供的方法，通过在PDSCH的时隙n+k上向终端发送上行数据的反馈信息(ACK或NACK)，可以使得终端能够在尽可能短的时间内获知上行数据的反馈信息，并且在反馈信息是NACK时对该上行数据进行重传，从而保证了该重传过程的及时性，能够满足eURLLC业务的时延要求。
上述步骤201和步骤205可以单独实现成为终端侧的控制信息的传输方法，上述步骤202、步骤203和步骤204可以单独实现成为基站侧的控制信息的传输方法。
图3示出了本申请一个示意性实施例提供的控制信息的传输方法的流程图。该反馈方法可以由图1所示的通信系统来执行，该方法包括：
步骤301，基站向终端配置k；
基站向终端配置k的方式，包括但不限于如下两种方式中的任意一种：
1、基站采用目标PDCCH格式向终端配置K；
目标PDCCH格式是用于向终端配置PUSCH的资源的PDCCH格式。目标PDCCH格式可以是PDCCH格式0_0或PDCCH格式0_1。目标PDCCH格式可理解为采用了目标PDCCH格式的下行控制信息(Downlink Control Information,简称：DCI)。
示意性的，在DCI格式0_0和DCI格式0_1中添加N个比特，用于指示K值。一般K的取值为0或者1，因此N的取值为1，即用1个比特表征即可， 但本申请不排除N的取值为大于1的整数。
2、基站采用RRC信令向终端配置K。
步骤302，终端接收基站配置的k；
需要说明的是，上述步骤301和步骤302是可选步骤。在一些实施例中，K的取值可以采用默认配置，比如默认取值为0，也即必须在指定时隙内的PDSCH进行ACK/NACK反馈，该指定时隙是用于发送上行数据的PUSCH的最后一个符号所在的时隙。
步骤303，终端在PUSCH的时隙n上向基站发送上行数据；
终端根据目标PDCCH上确定PUSCH上的时隙n中的时频资源，采用时隙n中的时频资源向基站发送上行数据。
步骤304，基站在PUSCH的时隙n上接收终端发送的上行数据；
步骤305，基站生成上行数据的反馈信息，该反馈信息包括ACK或NACK；
当上行数据接收成功时，基站生成ACK；当未能接收到上行数据，或，接收到上行数据且该上行数据的CRC失败时，基站生成NACK。
步骤306，基站在PDSCH的时隙n+k的指定频域位置上向终端发送控制信息；
可选地，该控制信息包括：ACK或NACK。在其他实施例中，该控制信息也可以用于携带其他信息，比如，PUSCH的信道质量信息、终端的功率控制信息等。本实施例以控制信息包括ACK或NACK来表示，但不限定控制信息的具体携带内容。
步骤307，终端在PDSCH的时隙n+k的指定频域位置上接收基站发送的控制信息；
步骤308，当控制信息包括ACK时，终端在指定资源位置上发送下一上行数据；
其中，指定资源位置是基站采用PDCCH配置的资源位置，该资源位置可以由；或，指定资源位置是预配置的用于非授权传输的资源位置。
步骤309，基站接收终端在指定资源位置上发送的下一上行数据；
步骤310，当控制信息包括NACK时，终端在指定资源位置上重传上行数据；
步骤311，基站接收终端在指定资源位置上重传的上行数据。
综上所述，本实施例提供的方法，通过在PDSCH的时隙n+k上向终端发送 上行数据的反馈信息(ACK或NACK)，可以使得终端能够在尽可能短的时间内获知上行数据的反馈信息，并且在反馈信息是NACK时对该上行数据进行重传，从而保证了该重传过程的及时性，能够满足eURLLC业务的时延要求。
本实施例提供的方法，通过将k默认配置为0，既能保证上行数据的ACK和NACK能及时传输至终端，从而指示终端在尽量短的时间内启动上行数据的重传，还能够节省基站和终端之间的控制信令的消耗。
需要说明的一点是，上述实施例中由终端执行的步骤可以单独实现成为终端侧的上行数据的重传方法，由基站执行的步骤可以单独实现成为基站侧的上行数据的反馈方法。
需要说明的另一点是，上述各个实施例还可以由本领域技术人员自由拆分和/或组合成为新的实施例，对此不加以限定。
在基于图3的可选实施例中，上述指定频域位置位于导频信号所占据的频域资源位置的两侧。如图4所示，PDSCH在做资源映射时，不必考虑ACK/NACK可能占用的比特；在ACK/NACK映射时，直接占据原本由PDSCH所占的比特。
