Description

HARQ-ACK的反馈方法、终端设备 技术领域
本申请涉及通信领域，尤其涉及一种HARQ-ACK的反馈方法、终端设备。
背景技术
通常，终端设备在与网络设备通信的过程中，网络设备在向终端设备发送物理下行共享信道(PDSCH，Physical Downlink Shared Channel)或释放半持续性调度(SPS，Semi-Persistent Scheduling)PDSCH的物理下行控制信道(PDCCH，Physical Downlink Control Channel)后，终端设备需要向网络设备进行混合自动重传请求确认(HARQ-ACK，Hybrid Automatic Repeat request-Acknowledgement)反馈，以便网络设备确定终端设备是否接收到PDSCH或释放SPS PDSCH的PDCCH。
随着非授权频谱在未来通信系统中的使用越来越频繁，以及终端设备与网络设备进行通信时支持的业务类型越来越复杂，网络设备越来越多的在非授权频谱中的混合业务下与终端设备进行通信。网络设备在非授权频谱中的混合业务下与终端设备进行通信时，在向终端设备发送PDSCH或释放SPS PDSCH的PDCCH后，同样需要终端设备进行HARQ-ACK反馈。然而，目前还缺少一种有效地方法可以使得终端设备可以在非授权频谱中的混合业务下进行HARQ-ACK反馈。
发明内容
本申请实施例提供一种HARQ-ACK的反馈方法、终端设备，以解决终端设备在非授权频谱中的混合业务下，无法有效地向网络设备进行HARQ-ACK反馈的问题。
为了解决上述技术问题，本申请是这样实现的：
第一方面，提供了一种HARQ-ACK的反馈方法，包括：接收来自网络设备的第一PDCCH，所述第一PDCCH用于调度第一PDSCH，所述第一PDCCH中包括指示信息，所述指示信息中包括触发域，所述触发域用于触发对已调度的其他PDSCH的HARQ-ACK反馈，所述其他PDSCH中包括与所述第一PDSCH对应相同或不同HARQ-ACK码本的PDSCH；根据所述指示信息，对所述第一PDSCH和所述其他PDSCH进行HARQ-ACK反馈。
第二方面，提供了一种终端设备，该终端设备包括：接收模块，接收来自网络设备的第一PDCCH，所述第一PDCCH用于调度第一PDSCH，所述第一PDCCH中包括指示信息，所述指示信息中包括触发域，所述触发域用于触发对已调度的其他PDSCH的HARQ-ACK反馈，所述其他PDSCH中包括与所述第一PDSCH对应相同或不同HARQ-ACK码本的PDSCH；反馈模块，根据所述指示信息，对所述第一PDSCH和所述其他PDSCH进行HARQ-ACK反馈。
第三方面，提供了一种终端设备，该终端设备包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第一方面所述的方法的步骤。
第四方面，提供了一种计算机可读存储介质，所述计算机可读存储介质上存储计 算机程序，所述计算机程序被处理器执行时实现如第一方面所述的方法的步骤。
在本申请实施例中，网络设备和终端设备在非授权频谱中的混合业务下进行通信的过程中，网络设备在向终端设备发送PDCCH时，可以在PDCCH中指示触发域，其中，该触发域用于触发对已调度的其他PDSCH的HARQ-ACK反馈，其他PDSCH中包括与当前调度的PDSCH对应相同或不同HARQ-ACK码本的PDSCH，终端设备在接收到来自网络设备的PDCCH后，可以根据网络设备的指示，对当前调度的PDSCH和已调度的其他PDSCH进行HARQ-ACK反馈。这样，由于网络设备可以通过触发域向终端设备指示是否触发对已调度的其他PDSCH的HARQ-ACK反馈，因此，终端设备可以基于网络设备的指示，有效地向网络设备进行HARQ-ACK反馈。

具体实施方式
通常，终端设备在与网络设备通信的过程中，网络设备向终端设备发送PDSCH后，终端设备需要向网络设备进行HARQ-ACK反馈，以便网络设备确认终端设备是否接收到PDSCH。
在一个典型的应用场景中，当终端设备和网络设备在非授权频谱下进行通信时，终端设备在向网络设备进行HARQ-ACK反馈时，由于网络设备只有在信道的状态为空闲时才可以向网络设备反馈HARQ-ACK，因此，为了避免由于信道状态为忙时导致的无法向网络设备反馈HARQ-ACK的问题，可以采用触发反馈的反馈机制，该机制可以在调度PDSCH的PDCCH中指示当前调度的PDSCH属于哪一个PDSCH组(即PDSCH group)，并通过PDCCH触发相应的PDSCH组反馈HARQ-ACK。
在另一个典型的应用场景中，当终端设备和网络设备在混合业务下进行通信时，考虑到不同的业务类型的需求不同，终端设备可以针对不同的业务类型同时构建多个HARQ-ACK码本(即HARQ-ACK-codebook)，多个HARQ-ACK码本相互独立，且一个HARQ-ACK码本可以对应一个业务类型，包括不同的PDSCH组，属于一个HARQ-ACK码本的PDSCH可以通过一个PUCCH进行HARQ-ACK反馈。
然而，当终端设备和网络设备在非授权频谱中的混合业务下进行通信时，即在终端设 备工作在非授权频段且同时支持多种不同的业务类型的应用场景中，终端设备目前还无法有效地向网络设备进行HARQ-ACK反馈。
有鉴于此，本申请实施例提供一种HARQ-ACK的反馈方法、终端设备，该方法包括：接收来自网络设备的第一物理下行控制信道PDCCH，所述第一PDCCH中包括指示信息，所述指示信息中包括触发域和所述第一PDCCH调度的第一PDSCH对应的PDSCH组指示域，所述触发域用于触发对已调度的其他PDSCH的HARQ-ACK反馈，所述其他PDSCH中包括与所述第一PDSCH对应相同或不同的HARQ-ACK码本下的同PDSCH组或不同PDSCH组的PDSCH；根据所述指示信息，对所述第一PDSCH和所述其他PDSCH进行HARQ-ACK反馈。
这样，由于网络设备可以向终端设备指示是否触发对已调度的其他PDSCH的HARQ-ACK反馈，因此，终端设备可以基于网络设备的指示，有效地向网络设备进行HARQ-ACK反馈。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的技术方案，可以应用于各种通信系统，例如：长期演进(LTE，Long Term Evolution)/增强长期演进(LTE-A，Long Term Evolution advanced)系统、LTE频分双工(FDD，Frequency Division Duplex)系统、LTE时分双工(TDD，Time Division Duplex)系统、通用移动通信系统(UMTS，Universal Mobile Telecommunications System)或全球互联微波接入(WiMAX，Worldwide Interoperability for Microwave Access)通信系统、5G系统，或者说新空口(NR，New Radio)系统等。
终端设备可以理解为用户设备(UE，User Equipment)，也可称之为移动终端(Mobile Terminal)、移动用户设备等，可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，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，也可以是无人机、飞行器等飞行设备，它们与无线接入网交换语言和/或数据。
网络设备可以理解为核心网，也可以理解为基站，其中，基站可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB)及5G基站(gNB)，以及后续演进通信系统中的网络侧设备，本申请并不限定，但为描述方便，下述实施例以gNB为例进行说明。
以下结合附图，详细说明本申请各实施例提供的技术方案。
图1为本申请的一个实施例HARQ-ACK的反馈方法的流程示意图，该方法可以由电子设备执行，例如终端设备。换言之，所述方法可以由安装在终端设备的软件或硬件来执行。如图所示，该方法可以包括以下步骤。。
S102：接收来自网络设备的第一PDCCH，所述第一PDCCH用于调度第一PDSCH，所述第一PDCCH中包括指示信息，所述指示信息中包括触发域，所述触发域用于触发对已调度的其他PDSCH的HARQ-ACK反馈，所述其他PDSCH中包括与所述第一PDSCH 对应相同或不同HARQ-ACK码本的PDSCH。
在S102中，在非授权频谱中的混合业务下，网络设备可以向终端设备发送物理下行控制信道(PDCCH，Physical Downlink Control Channel)，为了便于区分，这里可以由第一PDCCH表示。
本申请实施例中，第一PDCCH可以用于调度物理下行共享信道(PDSCH，Physical Downlink Shared Channel)，这里为了便于区分，可以由第一PDSCH表示。第一PDCCH中可以包括指示信息，指示信息中至少可以包括触发域，触发域可以用于触发对已调度的其他PDSCH的HARQ-ACK反馈。
需要说明的是，在本申请实施例中，终端设备可以配置同时构建多于一个HARQ-ACK码本(即HARQ-ACK-codebook)，其中，一个HARQ-ACK码本可以对应一个PDSCH组(即同一个HARQ-ACK码本下的PDSCH不区分PDSCH组)，也可以对应多个PDSCH组(即同一个HARQ-ACK码本下的PDSCH区分不同的PDSCH组)，一个PDSCH组可以对应多个PDSCH，一个HARQ-ACK码本可以对应一个业务类型，该业务类型可以是增强移动宽带(eMBB，Enhance Mobile Broadband)，也可以是超高可靠超低时延通信(URLLC，ultra-reliable and low-latency Communications)，还可以是大规模物联网(mMTC，massive Machine Type of Communication)等。
还需要说明的是，一个HARQ-ACK码本可以对应一个业务类型只是针对一种典型的情况，在实际操作中，对于一个PDSCH的HARQ-ACK所对应的HARQ-ACK码本取决于网络设备的指示，而网络设备可以不指示业务类型，在这种情况下，终端设备可以不需要关心一个HARQ-ACK码本是否对应一个业务类型。
这样，由于终端设备可以配置同时构建多个HARQ-ACK码本，因此，上述已调度的其他PDSCH中至少可以包括以下两种PDSCH：与第一PDSCH属于同一个HARQ-ACK码本的PDSCH、与第一PDSCH属于不同的HARQ-ACK码本的PDSCH。
进一步地，由于一个HARQ-ACK码本可以对应一个或多个PDSCH组，因此，上述已调度的其他PDSCH中至少可以包括以下四种PDSCH：
与第一PDSCH属于同一个HARQ-ACK码本且同一个PDSCH组的PDSCH、与第一PDSCH属于同一个HARQ-ACK码本且不同PDSCH组的PDSCH、与第一PDSCH属于不同HARQ-ACK码本且同一个PDSCH组的PDSCH、与第一PDSCH属于不同HARQ-ACK码本且不同PDSCH组的PDSCH。
需要说明的是，上述与第一PDSCH属于不同HARQ-ACK码本且同一个PDSCH组的PDSCH中的同一个PDSCH组是指对应的PDSCH的组号或者在各自HARQ-ACK码本内的PDSCH组序号相同，并不表示其属于一个PDSCH组(由于属于不同的HARQ-ACK码本)，同理与第一PDSCH属于不同HARQ-ACK码本且不同PDSCH组的PDSCH是指对应的PDSCH的组号或者在各自HARQ-ACK码本内的PDSCH组序号不同。
本实施例中，在终端设备配置同时构建多个HARQ-ACK码本的情况下，网络设备在向终端设备发送第一PDCCH时，还可以指示第一PDCCH调度的第一PDSCH的HARQ-ACK属于哪个HARQ-ACK码本。具体地，网络设备可以通过以下至少一种指示第一PDSCH的HARQ-ACK属于哪个HARQ-ACK码本：下行控制信息格式(DCI format，Downlink Control Information format)、DCI中某些比特数、无线网络临时鉴定(RNTI)、 控制资源组(CORESET，Control-Resource Set)、搜索空间(search space)。
此外，在一个HARQ-ACK码本对应多个PDSCH组的情况下，网络设备在向终端设备发送第一PDCCH时，第一PDCCH的指示信息中还可以包括第一PDSCH对应的PDSCH组指示域，其中，PDSCH组指示域可以用于指示第一PDSCH属于哪个PDSCH组。
网络设备在向终端设备发送第一PDCCH后，终端设备可以接收来自网络设备的第一PDCCH。其中，若网络设备指示了第一PDSCH所属的HARQ-ACK码本，终端设备还可以在接收到第一PDCCH时，在物理层区分第一PDSCH属于哪一个HARQ-ACK码本；若网络设备指示了第一PDSCH所属的PDSCH组，终端设备还可以在接收到第一PDCCH时，基于指示确定第一PDSCH属于哪一个PDSCH组。
为了便于理解，本申请实施例中可以以网络设备指示了第一PDSCH所属的PDSCH组为例进行说明，其中，已调度的其他PSDCH中可以包括指示了所属PDSCH组的PDSCH，也可以包括没有指示所属PDSCH组的PDSCH。
S104：根据所述指示信息，对所述第一PDSCH和所述其他PDSCH进行HARQ-ACK反馈。
在S104中，终端设备在接收到来自网络设备的第一PDCCH后，可以根据第一PDCCH中的指示信息，对第一PDCCH调度的第一PDSCH以及已调度的其他PDSCH进行HARQ-ACK反馈。
需要说明的是，在S102中网络设备下发的第一PDCCH中还可以包括k1(第一PDSCH到HARQ-ACK反馈的定时指示)，且k1为数值(当k1为数值时，说明网络设备指示终端设备在第一PDSCH对应的PUCCH(由网络设备指示)上进行定时的HARQ-ACK反馈，具体是在接收到第一PDSCH的k1个时隙或子时隙后进行第一PDSCH的HARQ-ACK反馈)，这样，终端设备在对第一PDSCH和其他PDSCH进行HARQ-ACK反馈时，可以根据k1在第一PDSCH对应的PUCCH上进行定时的HARQ-ACK反馈。
在第一种实现方式中：
指示信息中的触发域中可以包括第一指示信息，第一指示信息用于指示是否触发对第二PDSCH的HARQ-ACK反馈。其中，第二PDSCH为已调度的其他PDSCH中的一个或多个PDSCH，且第二PDSCH与第一PDSCH对应相同的HARQ-ACK码本，不同的PDSCH组。
这样，终端设备在对第一PDSCH进行HARQ-ACK反馈时，如果第一指示信息指示触发对第二PDSCH的HARQ-ACK反馈，那么，终端设备将在第一PDSCH对应的物理上行控制信道(PUCCH，Physical Uplink Control Channel)上传输第一PDSCH的HARQ-ACK和第二PDSCH的HARQ-ACK。其中，第一PDSCH对应的PUCCH可以由第一PDCCH的指示确定。
可选地，如果第一指示信息指示不触发对第二PDSCH的HARQ-ACK反馈，那么，终端设备将不会在第一PDSCH对应的PUCCH上传输第二PDSCH的HARQ-ACK。
需要说明的是，在指示信息的触发域中仅包括第一指示信息的情况下，触发域的比特数与终端设备仅构建一个HARQ-ACK码本时对应的触发域的比特数相同，例如一个HARQ-ACK码本的PDSCH分为2个PDSCH组时，触发域为1bit用于触发除当前调度的PDSCH之外的另一个PDSCH组的HARQ-ACK反馈。
为了便于理解，可以参见图2。
图2中，网络设备通过PDCCH1调度了PDSCH1，并指示终端设备在PDSCH1对应的PUCCH1上反馈PDSCH1的HARQ-ACK1，此外，网络设备还指示了PDSCH1属于HARQ-ACK码本0(即图2所示的H＝0)和PDSCH组0(即图2所示的G＝0)。之后，终端设备在传输PUCCH1时，由于检测到信道为忙，因此无法发送PUCCH1，即无法在PUCCH1上传输PDSCH1的HARQ-ACK1。需要说明的是，如前面所述，PDSCH1属于HARQ-ACK码本0而HARQ-ACK码本即H的指示可能是通过PDCCH1对应的DCI格式、DCI中某些比特数、RNTI、CORESET、search space等中的至少一项指示的。
之后，网络设备通过PDCCH2调度了PDSCH2，并指示终端设备在PDSCH2对应的PUCCH2上反馈PDSCH2的HARQ-ACK2，此外，网络设备还指示了PDSCH2属于HARQ-ACK码本0和PDSCH组1，触发域包含1bit(假设该HARQ-ACK码本有两个PDSCH组)，用于触发与当前调度的PDSCH属于相同HARQ-ACK码本的不同PDSCH组的PDSCH的HARQ-ACK反馈，且指示触发了对另一PDSCH组的PDSCH的HARQ-ACK反馈(即图2所示的T＝1)。之后，终端设备在对PDSCH2进行HARQ-ACK反馈时，将在PUCCH2上传输PDSCH组0(PDSCH1)的HARQ-ACK1和PDSCH组1(PDSCH2)的HARQ-ACK2。
可选地，若图2的PDCCH2中指示不触发对另一PDSCH组的PDSCH(即PDSCH1)的HARQ-ACK反馈，即图2所示的T＝0，则终端设备将不会在PUCCH2上传输PDSCH组0(PDSCH1)的HARQ-ACK1。
需要说明的是，图2中仅对终端设备构建的一个HARQ-ACK码本进行了说明，如果终端设备同时只构建一个HARQ-ACK码本，则上述HARQ-ACK码本指示H可以不需要指示。在终端同时构建多个HARQ-ACK码本的情况下，不同HARQ-ACK码本的PDSCH的分组以及HARQ-ACK触发传输都是在每个HARQ-ACK码本内进行的，相互之间互不影响。
在第二种实现方式中：
指示信息中的触发域中除了可以包括上述第一指示信息外，还可以包括第二指示信息，第二指示信息用于指示是否触发对第三PDSCH的HARQ-ACK反馈。其中：
第三PDSCH为已调度的其他PDSCH中的一个或多个PDSCH，且第三PDSCH与第一PDSCH对应不同的HARQ-ACK码本，相同的PDSCH组；或者，第三PDCSH与第一PDSCH对应不同的HARQ-ACK码本，且，第三PDSCH中包括多个PDSCH组中的PDSCH，多个PDSCH组可以是一个HARQ-ACK码本下的所有PDSCH组(在这种情况下，也可以视为该HARQ-ACK码本下的PDSCH没有区分不同的PDSCH组)。
这样，终端设备在对第一PDSCH进行HARQ-ACK反馈时，如果第二指示信息指示触发对第三PDSCH的HARQ-ACK反馈，那么，终端设备将在第一PDSCH对应的PUCCH上传输第一PDSCH的HARQ-ACK和第三PDSCH的HARQ-ACK。
可选地，如果第二指示信息指示不触发对第三PDSCH的HARQ-ACK反馈，那么，终端设备将不会在第一PDSCH对应的PUCCH上传输第三PDSCH的HARQ-ACK。
需要说明的是，在指示信息的触发域中包括第一指示信息和第二指示信息的情况下，第一指示信息和第二指示信息可以是不同的指示信息，例如触发域中的第一指示信息和第 二指示信息的比特数可以是2，其中，第一个比特数可以是第一指示信息的比特数，第二个比特数是第二指示信息的比特数，或者，也可以是第一个比特数为第二指示信息的比特数，第二个比特数为第一指示信息的比特数，这里不做具体限定。或者第一指示信息和第二指示信息可以是相同的指示信息。例如触发域中第一指示信息和第二指示信息共用1比特，该比特用于同时触发第二PDSCH和第三PDSCH的HARQ-ACK反馈。
为了便于理解，可以参见图3。
图3中，网络设备通过PDCCH1调度了PDSCH1，并指示终端设备在PDSCH1对应的PUCCH1上反馈PDSCH1的HARQ-ACK1，此外，网络设备还指示了PDSCH1属于HARQ-ACK码本0(即H＝0)和PDSCH组0(即G＝0)。之后，终端设备在传输PUCCH1时，检测到信道为忙，无法在PUCCH1上传输PDSCH1的HARQ-ACK1。
之后，网络设备通过PDCCH2调度了PDSCH2，并指示终端设备在PDSCH2对应的PUCCH2上反馈PDSCH2的HARQ-ACK2，此外，网络设备还指示了PDSCH2属于HARQ-ACK码本1和PDSCH组0，之后，终端设备在传输PUCCH2时，检测到信道为忙，无法在PUCCH2上传输PDSCH2的HARQ-ACK2。
之后，网络设备通过PDCCH3调度了PDSCH3，并指示终端设备在PDSCH3对应的PUCCH3上反馈PDSCH3的HARQ-ACK3，此外，网络设备还指示了PDSCH3属于HARQ-ACK码本1和PDSCH组1，之后，终端设备在传输PUCCH3时，检测到信道为忙，无法在PUCCH3上传输PDSCH3的HARQ-ACK3。
之后，网络设备通过PDCCH4调度了PDSCH4，并指示终端设备在PDSCH4对应的PUCCH4上反馈PDSCH4的HARQ-ACK4，此外，网络设备还指示了PDSCH4属于HARQ-ACK码本0和PDSCH组1，且在触发域的第一个比特(即图3所示的T的第一个“1”)指示触发对同HARQ-ACK码本下(H＝0)不同PDSCH组(G＝0)的PDSCH1的HARQ-ACK反馈，第二个比特(即图3所示的T的第二个“1”)指示触发对不同HARQ-ACK码本下(H＝1)的PDSCH组的反馈。
基于第二种实现方式，若触发域中的第二个比特指示触发对不同HARQ-ACK码本下相同PDSCH组的PDSCH的HARQ-ACK反馈，则终端设备将在PUCCH4上传输PDSCH1、PDSCH3以及PDSCH4各自的HARQ-ACK；若触发域中的第二个比特指示触发对不同HARQ-ACK码本下所有PDSCH组的PDSCH的HARQ-ACK反馈，则终端设备将在PUCCH4上传输PDSCH1、PDSCH2、PDSCH3以及PDSCH4各自的HARQ-ACK。在图3中，仅示出了在PUCCH4上传输PDSCH1、PDSCH2、PDSCH3以及PDSCH4各自的HARQ-ACK的情况。
另一种实现方式是，触发域仅有1比特，即图3中的T＝11改为T＝1，该1比特可以用于：
(1)触发当前调度的PDSCH的HARQ-ACK和与当前调度的PDSCH属于不同HARQ-ACK码本且对应相同PDSCH组号的PDSCH的HARQ-ACK反馈，此时图3中的终端设备将在PUCCH4上反馈PDSCH3以及PDSCH4各自对应的HARQ-ACK；
(2)触发第二PDSCH的HARQ-ACK和与当前调度的PDSCH属于不同HARQ-ACK码本的所有PDSCH组号的PDSCH的HARQ-ACK反馈，此时图3中的终端设备将在PUCCH4上反馈PDSCH2、PDSCH3以及PDSCH4各自对应的HARQ-ACK；
(3)触发当前调度的PDSCH的HARQ-ACK、与当前调度的PDSCH属于相同HARQ-ACK码本且对应不同PDSCH组号的PDSCH的HARQ-ACK反馈、与当前调度的PDSCH属于不同HARQ-ACK码本且对应相同PDSCH组号的PDSCH的HARQ-ACK反馈，此时图3中的终端设备将在PUCCH4上反馈PDSCH1、PDSCH3以及PDSCH4各自对应的HARQ-ACK；
(4)触发当前调度的PDSCH的HARQ-ACK、与当前调度的PDSCH属于相同HARQ-ACK码本且对应不同PDSCH组号的PDSCH的HARQ-ACK反馈、与当前调度的PDSCH属于不同HARQ-ACK码本的所有PDSCH组号的PDSCH的HARQ-ACK反馈，此时图3中的终端设备将在PUCCH4上反馈PDSCH1、PDSCH2、PDSCH3以及PDSCH4各自对应的HARQ-ACK。
在第三种实现方式中：
指示信息中的触发域中除了可以包括上述记载的第一指示信息外，还可以包括第三指示信息，第三指示信息用于指示是否触发对第四PDSCH和第五PDSCH的HARQ-ACK反馈。其中：
第四PDSCH和第五PDSCH均可以是已调度的其他PDSCH中的一个或多个PDSCH，第四PDSCH和第五PDSCH对应相同HARQ-ACK码本下的不同PDSCH组，且第四PDSCH和第五PDSCH对应的HARQ-ACK码本与第一PDSCH对应的HARQ-ACK码本不同。
这样，终端设备在对第一PDSCH进行HARQ-ACK反馈时：
如果第三指示信息指示触发对第四PDSCH和第五PDSCH的HARQ-ACK反馈，那么，终端设备将在第一PDSCH对应的PUCCH上传输第一PDSCH、第四PDSCH和第五PDSCH各自的HARQ-ACK；
如果第三指示信息指示触发对第四PDSCH的HARQ-ACK反馈，则终端设备将在第一PDSCH对应的PUCCH上传输第一PDSCH和第四PDSCH各自的HARQ-ACK，其中，由于第三指示信息没有指示触发对第五PDSCH的HARQ-ACK反馈，因此，终端设备将不会在第一PDSCH对应的PUCCH上传输第五PDSCH的HARQ-ACK；
如果第三指示信息指示触发对第五PDSCH的HARQ-ACK反馈，则终端设备将在第一PDSCH对应的PUCCH上传输第一PDSCH和第五PDSCH各自的HARQ-ACK，其中，由于第三指示信息没有指示触发对第四PDSCH的HARQ-ACK反馈，因此，终端设备将不会在第一PDSCH对应的PUCCH上传输第四PDSCH的HARQ-ACK。
需要说明的是，在指示信息的触发域中包括第一指示信息和第三指示信息的情况下，触发域的比特数可以是3，其中，第一个比特数可以是第一指示信息的比特数，第二和第三个比特数可以是第三指示信息的比特数，且，第二个比特数为组号较低的PDSCH组的比特数，第三个比特数为组号较高的PDSCH组的比特数，或者，也可以是第二个比特数为组号较高的PDSCH组的比特数，第三个比特数为组号较低的PDSCH组的比特数，这里不做具体限定，本实施例可以以第二个比特数为组号较低的PDSCH组的对应的比特，第三个比特数为组号较高的PDSCH组对应的比特为例进行说明。
为了便于理解，可以参见图4。
图4中，网络设备通过PDCCH1调度了PDSCH1，并指示终端设备在PDSCH1对应的PUCCH1上反馈PDSCH1的HARQ-ACK1，此外，网络设备还指示了PDSCH1属于 HARQ-ACK码本0(即H＝0)和PDSCH组0(即G＝0)。之后，终端设备在传输PUCCH1时，检测到信道为忙，无法在PUCCH1上传输PDSCH1的HARQ-ACK1。
之后，网络设备通过PDCCH2调度了PDSCH2，并指示终端设备在PDSCH2对应的PUCCH2上反馈PDSCH2的HARQ-ACK2，此外，网络设备还指示了PDSCH2属于HARQ-ACK码本1和PDSCH组0，之后，终端设备在传输PUCCH2时，检测到信道为忙，无法在PUCCH2上传输PDSCH2的HARQ-ACK2。
之后，网络设备通过PDCCH3调度了PDSCH3，并指示终端设备在PDSCH3对应的PUCCH3上反馈PDSCH3的HARQ-ACK3，此外，网络设备还指示了PDSCH3属于HARQ-ACK码本1和PDSCH组1，之后，终端设备在传输PUCCH3时，检测到信道为忙，无法在PUCCH3上传输PDSCH3的HARQ-ACK3。
之后，网络设备通过PDCCH4调度了PDSCH4，并指示终端设备在PDSCH4对应的PUCCH4上反馈PDSCH4的HARQ-ACK4，此外，网络设备还指示了PDSCH4属于HARQ-ACK码本0和PDSCH组1，且在触发域的第一个比特(即图4所示的T的第一个“1”)指示触发对相同HARQ-ACK码本下(H＝0)不同PDSCH组(G＝0)的PDSCH1的HARQ-ACK反馈，第二个比特(即图4所示的T的第二个“1”)指示触发对不同HARQ-ACK码本下(H＝1)的PDSCH组0的反馈，第三个比特(即图4所示的T的第三个“0”)指示不触发对不同HARQ-ACK码本下(H＝1)的PDSCH组1的反馈。这样，终端设备将在PUCCH4上传输PDSCH1、PDSCH2以及PDSCH4各自的HARQ-ACK，不传输PDSCH3的HARQ-ACK3。
需要说明的是，在上述记载的第二种实现方式和第三种实现方式中，终端设备需要在一个PUCCH上传输不同HARQ-ACK码本的不同PDSCH组的HARQ-ACK，其中PDCCH中的累积下行分配指示(C-DAI，counter-Downlink Assignment Indicator)/总共下行分配指示(T-DAI，total-Downlink Assignment indicator)的计算和指示则可以在每个HARQ-ACK码本的每个PDSCH组内进行，终端设备在构建HARQ-ACK码本时，可以将不同的HARQ-ACK码本对应的比特序列级联在一起，在每个HARQ-ACK码本内的比特序列则可以按照PDSCH组0，PDSCH组1的顺序构建。
此外，针对网络设备而言，由于网络设备可以在调度一个HARQ-ACK码本的PDSCH中触发其他HARQ-ACK码本的PDSCH的HARQ-ACK传输，因此，可以有效减少PDCCH的负载。
在第四种实现方式中，指示信息中还可以包括新反馈组指示(NFI，New Feedback group Indicator)，NFI用于指示是否对第六PDSCH进行HARQ-ACK反馈，其中，第六PDSCH可以是已调度的其他PDSCH中的一个或多个PDSCH，且，第六PDSCH和第一PDSCH对应相同的PDSCH组。
需要说明的是，在本实施例中，第六PDSCH与第一PDSCH可以是对应相同的HARQ-ACK码本，也可以是对应不同的HARQ-ACK码本，也可以是既包含与第一PDSCH属于相同HARQ-ACK码本的PDSCH又包含与第一PDSCH属于不同HARQ-ACK码本的PDSCH，这里不做具体限定。此外，NFI的指示方式为翻转指示，具体地，若当前调度PDSCH的PDCCH中的NFI相较于前一个调度PDSCH(属于同一个PDSCH组)对应的PDCCH中的NFI发生翻转，则指示不触发对第六PDSCH的HARQ-ACK反馈，若没有发生翻转， 则指示触发对第六PDSCH的HARQ-ACK反馈。
这样，终端设备在进行HARQ-ACK反馈时，若NFI指示触发对第六PDSCH的HARQ-ACK反馈(即NFI没有翻转)，则在第一PDSCH对应的PUCCH上传输第一PDSCH的HARQ-ACK和第六PDSCH的HARQ-ACK。
可选地，若NFI没有指示触发对第六PDSCH的HARQ-ACK反馈(即NFI发生了翻转)，则在第一PDSCH对应的PUCCH上将不会传输第六PDSCH的HARQ-ACK。
为了便于理解，可以参见图5。
图5中，网络设备通过PDCCH1调度了PDSCH1，并指示终端设备在PDSCH1对应的PUCCH1上反馈PDSCH1的HARQ-ACK1，此外，网络设备还指示了PDSCH1属于HARQ-ACK码本0(即H＝0)和PDSCH组0(即G＝0)，且NFI为0。之后，终端设备在传输PUCCH1时，检测到信道为忙，无法在PUCCH1上传输PDSCH1的HARQ-ACK1。
之后，网络设备通过PDCCH2调度了PDSCH2，并指示终端设备在PDSCH2对应的PUCCH2上反馈PDSCH2的HARQ-ACK2，此外，网络设备还指示了PDSCH2属于HARQ-ACK码本1和PDSCH组0，且NFI为0。之后，终端设备在传输PUCCH2时，检测到信道为忙，无法在PUCCH2上传输PDSCH2的HARQ-ACK2。
之后，网络设备通过PDCCH3调度了PDSCH3，并指示终端设备在PDSCH3对应的PUCCH3上反馈PDSCH3的HARQ-ACK3，此外，网络设备还指示了PDSCH3属于HARQ-ACK码本0和PDSCH组0，且NFI为0。这样，终端设备在传输PUCCH3时，由于NFI没有翻转(仍然为0)，因此，终端设备将在PUCCH3上传输PDSCH3的HARQ-ACK3以及与PDSCH3同PDSCH组的其他PDSCH的HARQ-ACK，具体可以是以下三种情况中的任一种(图5仅示出了以下第三种情况)：
第一种情况：终端设备将在PUCCH3上传输PDSCH3的HARQ-ACK3以及与PDSCH3属于相同HARQ-ACK码本相同PDSCH组的PDSCH1的HARQ-ACK1；
第二种情况：终端设备将在PUCCH3上传输PDSCH3的HARQ-ACK3以及与PDSCH3属于不同HARQ-ACK码本相同PDSCH组的PDSCH2的HARQ-ACK2；
第三种情况：终端设备将在PUCCH3上传输PDSCH3的HARQ-ACK3以及与PDSCH3属于相同和不同HARQ-ACK码本相同PDSCH组的PDSCH1和PDSCH2各自的HARQ-ACK。
需要说明的是，本实施例中，终端设备在进行HARQ-ACK反馈时，还可以结合非授权频谱下的同PDSCH组下的PDSCH的HARQ-ACK基于同一个PUCCH进行反馈以及定时反馈的方法。其中，在指示定时反馈时，可以在PDCCH中指示k1(PDSCH到HARQ-ACK反馈的定时指示)，若k1为非数值，则表征终端设备不需要对当前调度的PDSCH进行定时HARQ-ACK反馈，而是通过之后调度的同PDSCH组的PDSCH确定具体地反馈时间和PUCCH资源，若k1为数值，则表征终端设备需要在接收到PDSCH的k1个时隙或子时隙后进行HARQ-ACK反馈。
此外，上述记载的第四种实现方式也可以与上述记载的第一至第三种实现方式中的任一种相结合，这样，终端设备可以在不同的应用场景下，针对属于不同HARQ-ACK码本不同PDCSH组的PDSCH，有效地向网络设备进行HARQ-ACK反馈。
为了便于理解，可以参见图6、图7和图8。
在图6中，网络设备先后通过PDCCH1调度了PDSCH1，通过PDCCH2调度了PDSCH2，PDCCH3调度了PDSCH3，PDCCH4调度了PDSCH4，并指示了PDSCH1属于HARQ-ACK码本0(即H＝0)，PDSCH组0(即G＝0)，NFI＝0，4个时隙后反馈(k1＝4)，PDSCH2属于HARQ-ACK码本0，PDSCH组0，NFI＝0，k1＝3，PDSCH3属于HARQ-ACK码本0，PDSCH组1，NFI＝0，k1＝P(pending，非数值k1)，PDSCH4属于HARQ-ACK码本1，PDSCH组0，NFI＝0，k1＝1。
基于网络设备的指示，终端设备在进行HARQ-ACK反馈时，可以在PUCCH1上对属于相同HARQ-ACK码本相同PDSCH组的PDSCH1和PDSCH2进行HARQ-ACK反馈，在PUCCH2上对属于HARQ-ACK码本1的PDSCH4进行HARQ-ACK反馈，由于PDSCH3属于HARQ-ACK码本0的PDSCH组1，因此反馈时间和PUCCH资源待定。
由于终端设备在传输PUCCH1和PUCCH2前检测到信道为忙，因此，未能发送PUCCH1和PUCCH2，之后，网络设备又调度了PDSCH5，根据调度PDSCH5的PDCCH5，终端设备可以确定PDSCH5属于HARQ-ACK码本0的PDSCH组1，相对于PDSCH3的NFI，PDSCH5的NFI没有翻转，即表征终端设备需要在一个PUCCH资源(即PUCCH3)上反馈PDSCH3(与PDSCH5属于相同HARQ-ACK码本相同PDSCH组的PDSCH)和PDSCH5的HARQ-ACK，同时PDCCH5中的触发域T＝1，指示触发PDSCH5所在HARQ-ACK码本的另一个PDSCH组(即PDSCH组0)的PDSCH1和PDSCH2的HARQ-ACK反馈，因此，终端设备将在PDSCH5对应的PUCCH3上反馈PDSCH1、PDSCH2、PDSCH3和PDSCH5各自的HARQ-ACK。
之后，网络设备通过PDCCH6调度了PDSCH6，且指示PDSCH6属于HARQ-ACK码本1的PDSCH组0，NFI＝0，没有翻转(相对于相同HARQ-ACK码本相同PDSCH组的PDSCH4的NFI＝0)，如图6所示，因此终端设备将在PDSCH6对应的PUCCH4上反馈PDSCH4和PDSCH6各自的HARQ-ACK。
可选地，在图6中，网络设备在调度PDSCH5时，若PDCCH5中的触发域T＝11，即第一比特指示触发PDSCH5所在HARQ-ACK码本(HARQ-ACK码本0)的另一个PDSCH组(即PDSCH组0)的PDSCH3的HARQ-ACK反馈，以及第二比特指示触发与PDSCH5所在HARQ-ACK码本不同的另一个HARQ-ACK码本(即码本1)的PDSCH的HARQ-ACK反馈，如图7所示，则：
若触发域第二比特指示触发HARQ-ACK码本1的同PDSCH组(即PDSCH组0)的PDSCH的HARQ-ACK反馈，则终端设备将在PUCCH3上传输PDSCH1、PDSCH2、PDSCH3、PDSCH4和PDSCH5各自的HARQ-ACK。
若在触发域第二比特指示触发HARQ-ACK码本1的所有PDSCH组的PDSCH的HARQ-ACK反馈，则由于HARQ-ACK码本1的所有组只有PDSCH组0，因此，终端设备将在PUCCH3上传输PDSCH1、PDSCH2、PDSCH3、PDSCH4和PDSCH5各自的HARQ-ACK。
可选地，在图6中，网络设备在调度PDSCH5时，若PDCCH5中的触发域T＝110，即第一比特指示触发PDSCH5所在HARQ-ACK码本的另一个PDSCH组(即PDSCH组0)的PDSCH3的HARQ-ACK反馈，以及第二比特指示触发与PDSCH5所在HARQ-ACK码本不同的另一个HARQ-ACK码本(即码本1)的PDSCH的HARQ-ACK反馈，如图8所 示，则：
若触发域的第二个比特用于指示触发对HARQ-ACK码本1的PDSCH组0的PDSCH的HARQ-ACK反馈，第三个比特用于指示不触发对HARQ-ACK码本1的PDSCH组1的PDSCH的HARQ-ACK反馈，则，终端设备将在PUCCH3上传输PDSCH1、PDSCH2、PDSCH3、PDSCH4和PDSCH5各自的HARQ-ACK。
若触发域的第二个比特用于指示不触发对HARQ-ACK码本1的PDSCH组1的PDSCH的HARQ-ACK反馈，第三个比特用于指示触发对HARQ-ACK码本1的PDSCH组0的PDSCH的HARQ-ACK反馈，且T＝101，由于已调度的PDSCH中没有属于HARQ-ACK码本1的PDSCH组1的PDSCH且没有触发，因此，终端设备将在PUCCH3上传输PDSCH1、PDSCH2、PDSCH3和PDSCH5各自的HARQ-ACK(图8中并未示出)。
在本申请实施例中，网络设备和终端设备在非授权频谱中的混合业务下进行通信的过程中，网络设备在向终端设备发送PDCCH时，可以在PDCCH中指示触发域，其中，该触发域用于触发对已调度的其他PDSCH的HARQ-ACK反馈，其他PDSCH中包括与当前调度的PDSCH对应相同或不同HARQ-ACK码本的PDSCH，终端设备在接收到来自网络设备的PDCCH后，可以根据网络设备的指示，对当前调度的PDSCH和已调度的其他PDSCH进行HARQ-ACK反馈。这样，由于网络设备可以通过触发域向终端设备指示是否触发对已调度的其他PDSCH的HARQ-ACK反馈，因此，终端设备可以基于网络设备的指示，有效地向网络设备进行HARQ-ACK反馈。
