Description

DAI配置方法、指示方法、发送方法、装置及介质 技术领域
本申请涉及移动通信领域,特别涉及一种DAI(Downlink Assignment Index,下行链路分配索引)配置方法、指示方法、发送方法、装置及介质。
背景技术
目前,在无线通信网络中,终端设备与网络设备进行通信,且终端设备还可以向网络设备发送HARQ-ACK(Hybrid Automatic Repeat request Acknowledgement-ACK,混合自动重传请求确认)信息,以使网络设备确定终端设备对数据是否正确接收。
相关技术中,网络设备向终端设备发送DCI(Downlink Control Information,下行控制信息)消息,且可以采用DCI中携带的DAI域对发送的DCI消息进行计数,且终端设备根据DAI域生成动态HARQ-ACK码本,以向网络设备反馈终端设备是否正确接收消息。
相关技术中的计数DAI域均采用2比特来指示,然后采用计数DAI+j*4的方式,确定HARQ-ACK在HARQ-ACK码本中的位置,但在其它设计中,提出了将DAI域采用1比特来指示的方案。当在同一HARQ-ACK反馈窗口对应的多个DCI中,可能存在不同比特位的DAI时,会使得上述位置的确定过程发生冲突,无法正常使用。

本申请提供了一种DAI指示方法,终端设备接收DCI,根据DCI中的计数DAI域确定第三计数DAI,根据第三计数DAI确定DCI调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置。由于终端设备先根据计数DAI域确定了第三计数DAI,即使不同计数DAI域的比特位不同,也可以将根据计数DAI域转换为第三计数DAI,后续再根据第三计数DAI确定DCI调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置,防止出现由于计数DAI的比特位不同导致确定的HARQ-ACK的位置错误的情况,保证了确定的HARQ-ACK的位置的准确性。
本申请提供了一种DAI发送方法,DCI中的计数DAI域的第一比特位为0比特,说明在DCI中不存在计数DAI域,此时终端设备接收到该DCI后,获取该DCI指示的资源位置,在该资源位置上传输HARQ-ACK,可以保证终端设备准确传输HARQ-ACK,保证了HARQ-ACK传输的准确性。

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。
图1示出了本申请一个示例性实施例提供的通信系统的框图,该通信系统可以包括:接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站,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。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-U系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。为方便本申请实施例中,上述为终端设备14提供无线通信功能的装置统称为接入网设备。
终端设备14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,移动台(Mobile Station,MS),终端(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与终端设备14之间通过某种空口技术互相通信,例如Uu接口。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type  Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to everything,V2X)系统等。本申请实施例也可以应用于这些通信系统。
相关技术中,对于动态HARQ-ACK码本,一个PDSCH接收或者SPS释放的HARQ-ACK在一个HARQ-ACK码本中的位置与该PDSCH接收或者SPS释放在这个HARQ-ACK码本内的传输编号对应。
可选地,PDSCH接收或者SPS释放在HARQ-ACK码本内的位置由计数DAI取值指示。
需要说明的是,由于计数DAI域的比特位有限,仅采用计数DAI,不能使计数DAI与传输编号一一对应,因此采用取模的操作,确定计数DAI对应的传输编号。
其中,计数DAI域取值=MOD(PDSCH接收或者SPS释放在一个HARQ-ACK码本内的传输编号Y,4)。
例如,当Y=1,2,3,4,5,6时,根据上述公式,可以确定计数DAI=1,2,3,0,1,2。
并且,为了能确定计数DAI对应的Y,在协议中添加计数DAI翻转次数j的累计,且Y=计数DAI+j*4。
其中,当DAI的取值小于上一次DAI的取值时,将j的数值加1。
在同一个HARQ-ACK码本窗口中,如果计数DAI域的比特位为2个比特,则采用上述方式,可以依次确定出每个计数DAI对应的Y,且确定的Y值为正确的传输编号。
但是,如果在同一个HARQ-ACK码本中的HARQ-ACK对应的PDSCH接收或者SPS释放对应的计数DAI域的比特位不同时,采用上述方式确定HARQ-ACK的位置将会出现错误。
例如,如图1所示,在一个HARQ-ACK码本窗口内包含7个PDSCH传输,分别为0,1,2,3,4,5,6。这7个PDSCH传输依次轮询采用2比特的DAI和1比特的DAI指示,且DAI取值分别为表1中的第2行和第3行。可选地,根据DAI取值确定的翻转次数j如表1中的第4行所示,则采用上述方式计算得到的HARQ-ACK比特位的位置为0,1,2,5,8,9,10,则PDSCH传输3,4,5,6对应的HARQ-ACK比特位位置被错误地计算为5,8,9,10,导致实际PDSCH传输编号和计算出的PDSCH传输编号不一致,导致网络设备无法正确解读HARQ-ACK信息域与PDSCH的对应关系。
表1
实际传输次数Y 0 1 2 3 4 5 6
计数DAI值(2bit)=Ymod4 0   2   0   2
计数DAI值(1bit)=Ymod2   1   1   1  
计数DAI翻转次数(2bit)j 0 0 0 1 2 2 2
HARQ-ACK的位置=4*j+DAI值 0 1 2 5 8 9 10
本申请给出了上述技术问题的至少三种解决方案,以下分别进行阐述(排名不分先后)。
其中,图2所示的实施例是网络设备为终端设备配置的第一DCI格式的第一计数DAI域的第一比特位和第二DCI格式的第二计数DAI域的第二比特位相同,后续终端设备在根据第一计数DAI和第二计数DAI确定第一DCI格式调度的PDSCH接收或SPS release和第二DCI格式调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置的准确性。图3-图6所示的实施例是终端设备根据DCI中的计数DAI域,确定对应的第三计数DAI,确定的第三计数DAI为一个参考计数DAI,后续再根据该第三计数DAI确定DCI调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置。图7所示的实施例是终端设备直接根据接收的DCI确定资源位置,在该资源位置上发送DCI调度的PDSCH接收或者SPS release的HARQ-ACK。
针对第一种可能的解决方案:
图2示出了本申请一个示例性实施例提供的DAI的配置方法的流程图,应用于如图1所 示的终端设备和网络设备中,该方法包括以下内容中的至少部分内容:
步骤201,网络设备确定第一DCI格式中的第一计数DAI的第一比特位。
步骤202,终端设备确定第一DCI格式中的第一计数DAI的第一比特位。
可选地,第一比特位是协议约定的。其中,第一DCI格式可以为DCI格式1_1,DCI格式0_1,DCI格式1_0,DCI格式0_0中的任一项。
可选地,该第一比特位为1个比特,或者为2个比特。
步骤203,网络设备发送配置信息。
步骤204,终端设备接收配置信息。
其中,该配置信息用于配置第二DCI格式中的第二计数DAI的第二比特位。
终端设备可以先确定第一DCI格式中的第一计数DAI的第一比特位,再接收配置信息,根据该配置信息,确定第二DCI格式中的第二计数DAI的第二比特位。
可选地,终端设备可以先确定第一DCI格式中的第一计数DAI的第一比特位,再根据配置信息确定第二DCI格式中的第二计数DAI的第二比特位。或者,终端设备可以先确定第二DCI格式中的第二计数DAI的第二比特位,再根据配置信息确定第一DCI格式中的第一计数DAI的第二比特位。或者,终端设备可以同时确定第一DCI格式中的第一计数DAI的第一比特位和根据配置信息确定第二DCI格式中的第二计数DAI的第二比特位。
可选地,该第二DCI格式可以为DCI format0_2、DCI format1_2中的任一项。可选地,该第二比特位为1个比特,或者2个比特。
其中,该第一DCI格式调度的PDSCH接收或SPS release与第二DCI格式调度的PDSCH接收或SPS release在同一个HARQ-ACK码本反馈HARQ-ACK。
可选地,该配置信息由高层信令配置。
在一种可能实现方式中,第一比特位与第二比特位相同。
网络设备在配置DCI的DAI域时,如果网络设备配置DCI的DAI域的比特位不同,则会出现相关技术中确定的HARQ-ACK位置错误的情况,因此网络设备配置的第一比特位和第二比特位相同,终端设备即可根据具有相同比特位的第一DAI和第二DAI,确定HARQ-ACK的位置。
例如,在同一个HARQ-ACK码本窗口内的PDSCH 1由DCI格式1_1调度,且DCI格式1_1中的计数DAI域的比特位为2个比特,PDSCH 2由DCI格式1_2调度,那么DCI格式1_2中的计数DAI域也需要配置为2个比特。
又例如,如果第一HARQ-ACK码本窗口内的PDSCH 1和PDSCH 2由DCI格式1_1调度,且DCI格式1_1中的计数DAI域的比特位为2个比特,而第二HARQ-ACJ码本窗口内的PDSCH 3和PDSCH 4由DCI格式1_2调度。由于第一HARQ-ACK码本和第二HARQ-ACK码本为不同的HARQ-ACK码本,则DCI格式1_1中的计数DAI域的比特位和DCI格式1_2中的计数DAI域的比特位无需相同,DCI格式1_2中的计数DAI域的比特位可以为1个比特或者2个比特。
在另一种可能实现方式中,该第一比特位的有效比特位与第二比特位的有效比特位相同。
如果第一比特位和第二比特位不同时,则网络设备可以为终端设备配置有效比特位,以使第一比特位的有效比特位和第二比特位的有效比特位相同,后续终端设备根据第一DAI域的有效比特位和第二DAI域的有效比特位确定HARQ-ACK的位置,可以保证确定的HARQ-ACK的位置的准确性。
例如,在同一个HARQ-ACK码本窗口内的PDSCH 1由DCI格式1_1调度,且DCI格式1_1中的计数DAI域的比特位为2个比特,PDSCH 2由DCI格式1_2调度,那么DCI格式1_2中的计数DAI域为1个比特时,则配置DCI格式1_1中的计数DAI域的有效比特位为1个比特,DCI格式1_2中的计数DAI域的有效比特位也为1个比特。
可选地,第一比特位的有效比特位和第二比特位的有效比特位为:第一比特位和第二比特位的最小值。
例如,在同一个HARQ-ACK码本窗内的PDSCH 1由DCI format 1_1调度,DCI格式1_1中计数DAI域的比特位为2个比特,PDSCH 2由DCI格式1_2调度,DCI格式1_2中计数DAI域的比特位为1个比特,则DCI格式1_1或者DCI格式1_2中的计数DAI域的有效比特位为1个比特。
可选地,第一计数DAI的第一比特位中除有效比特位以外的其他比特位,用于指示第一计数DAI以外的其他信息,或者第二计数DAI的第二比特位中除有效比特位以外的其他比特位用于指示第二计数DAI以外的其他信息。
其中,其他信息包括以下至少一项:优先级信息;开环功率信息。
可选地,DCI格式1_1中计数DAI域中的最低的1个比特位用DAI计数,最高1比特位不用于DAI计数。此时,该计数DAI域中的最高的1个比特位可以用于指示其它信息,比如业务优先级,或总计DAI信息等等。
又例如,如果第一HARQ-ACK码本窗口内的PDSCH 1和PDSCH 2由DCI格式1_1调度,且DCI格式1_1中的计数DAI域的比特位为2个比特,而第二HARQ-ACJ码本窗口内的PDSCH 3和PDSCH 4由DCI格式1_2调度。由于第一HARQ-ACK码本和第二HARQ-ACK码本为不同的HARQ-ACK码本,则DCI格式1_1中的计数DAI域的比特位和DCI格式1_2中的计数DAI域的比特位无需相同,DCI格式1_2中的计数DAI域的比特位也可以为1个比特或者2个比特。而DCI格式1_1中的计数DAI域的有效比特位为2个比特。
需要说明的是,本申请实施例中的HARQ-ACK码本可以为类型2的HARQ-ACK码本。或者,本申请实施例中的HARQ-ACK码本还可以为类型1的HARQ-ACK码本,或者,本申请的HARQ-ACK码本可以为类型1的HARQ-ACK码本和类型2的HARQ-ACK码本。
其中,类型2的HARQ-ACK码本为动态HARQ-ACK码本,类型1的HARQ-ACK码为半静态HARQ-ACK码本。
步骤205,终端设备根据DCI中的计数DAI,确定DCI格式调度的PDSCH接收或释放半持续调度在一个HARQ-ACK码本反馈HARQ-ACK的位置。
终端设备确定DCI中的计数DAI域后,即可根据确定DCI格式中的计数DAI域的比特位,确定在一个HARQ-ACK码本反馈HARQ-ACK的位置。
本申请实施例提供的方法,终端设备确定第一DCI格式中的第一计数DAI的第一比特位,接收配置信息后,根据该配置信息,第二DCI格式中的第二计数DAI的第二比特位,且第一比特位和第二比特位相同,可以确定在一个HARQ-ACK码本HARQ-ACK对应的PDSCH接收或者SPS释放对应的计数DAI域的比特位相同,后续终端设备在根据计数DAI域确定HARQ-ACK位置时,可以保证确定HARQ-ACK的位置的准确性。
并且,当第一比特位的有效比特位与第二比特位的有效比特位相同时,也可以保证确定HARQ-ACK的位置的准确性。
通过对相关技术的描述,可以确定产生错误的原因主要是由于第一DAI域的第一比特位和第二DAI域的第二比特位不同,进行取模时的数值也不同,导致根据计数DAI确定DAI对应的翻转次数也会出现错误,因此,在图3-6所示的实施例中,根据计数DAI域确定第三计数DAI,该第三计数DAI改变了取模的数值,因此可以抵消由于第一DAI域的第一比特位和第二DAI域的第二比特位不同而产生的错误,后续终端设备再根据第三计数DAI,可以保证确定DCI调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置的准确性。
针对第二种可能的解决方案:
图3示出了本申请一个示例性实施例提供的DAI的指示方法的流程图,应用于如图1所示的终端设备和网络设备中,该方法包括以下内容中的至少部分内容:
步骤301,网络设备发送DCI。
在同一个HARQ-ACK码本窗口内,网络设备可以向终端设备发送一个或多个DCI。比如:

2、网络设备向终端设备发送多个DCI,多个DCI均为第二DCI格式;
3、网络设备向终端设备发送多个DCI,多个DCI中同时存在第一DCI格式和第二DCI格式。
本申请实施例以多个DCI中同时存在第一DCI格式和第二DCI格式来举例说明。
步骤302,终端设备接收DCI。
其中,每个DCI中包括计数DAI域。DCI的格式包括第一DCI格式和/或第二DCI格式。当DCI的格式为第一DCI格式,计数DAI为第一计数DAI,第一计数DAI的比特位为第一比特位;当DCI的格式为第二DCI格式,计数DAI为第二计数DAI,第二计数DAI的比特位为第二比特位。
步骤303,终端设备根据计数DAI确定第三计数DAI。

例如,当该DCI中的计数DAI为0时,确定第三计数DAI为0。
其中,当该第三计数DAI可以等于DCI中的计数DAI对正整数M取模得到的数时,采用第三计数DAI=取模(计数DAI,正整数M)表示。
例如,当该计数DAI的值为1,正整数M为2,则第三计数DAI=取模(1,2)=1。
另外,该第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数,采用第三计数DAI=取模(计数DAI-y,正整数M)+y表示。

其中,第一参数由第一比特位确定,第二参数由第二比特位确定。
可选地,第一参数等于2的第一比特位幂,第二参数等于2的第二比特位幂。
例如,该第一比特位为2,则2的第一比特位幂为4,第二比特位为1,则2的第二比特位幂为2。
在另一种可能实现方式中,正整数M为第一参数和第二参数的最大公约数。
例如,第一参数为4,第二参数为2,则第一参数和第二参数的最大公约数为2,确定正整数M为2。
其中,第一参数由第一比特位确定,第二参数由第二比特位确定。
可选地,第一参数等于2的第一比特位幂,第二参数等于2的第二比特位幂。
例如,该第一比特位为2,则2的第一比特位幂为4,第二比特位为1,则2的第二比特位幂为2。
可选地,第一参数对应第一DCI格式,第二参数对应第二DCI格式。
其中,第一DCI格式,可以为DCI格式1_1,DCI格式0_1,DCI格式1_0,DCI格式0_0中的任一项,该第二DCI格式可以为DCI format0_2、DCI format1_2中的任一项。
可选地,当第三计数DAI等于DCI中的计数DAI时,可以包括以下任一项:

2、当在同一个HARQ-ACK码本反馈HARQ-ACK对应的PDSCH接收或SPS release由第一DCI格式调度和第二DCI格式调度,且第一比特位和第二比特位相同时,第三计数DAI等于计数DAI。
3、当在同一个HARQ-ACK码本反馈HARQ-ACK对应的PDSCH接收或SPS release由第一DCI格式调度和第二DCI格式调度,且计数DAI的比特位为第一比特位和第二比特位中的最小值时,第三计数DAI等于计数DAI。
4、当在同一个HARQ-ACK码本反馈HARQ-ACK对应的PDSCH接收或SPS release由第一DCI格式调度和第二DCI格式调度,且2的计数DAI比特位幂为2的第一比特位幂和2的第二比特位幂的最大公约数时,第三计数DAI等于计数DAI。
5、在仅配置第一DCI格式或者第二DCI格式的情况下,第三计数DAI等于计数DAI。
6、在配置第一DCI格式和第二DCI格式,且第一比特位和第二比特位相同的情况下,第三计数DAI等于计数DAI。
7、在配置第一DCI格式和第二DCI格式,且计数DAI的比特位为第一比特位和第二比特位中的最小值时,第三计数DAI等于计数DAI。
8、在配置第一DCI格式和第二DCI格式,且2的计数DAI比特位幂为2的第一比特位幂和2的第二比特位幂的最大公约数时,第三计数DAI等于计数DAI。
可选地,当第三计数DAI可以等于DCI中的计数DAI对正整数M取模得到的数,或者第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数时,可以包括以下任一项:
1、当在同一个HARQ-ACK码本反馈HARQ-ACK对应的PDSCH接收或SPS release由第一DCI格式调度和第二DCI格式调度,且计数DAI的比特位大于第一比特位和第二比特位中的最小值时,第三计数DAI等于计数DAI对正整数M取模得到的数,或者,第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数。
2、当在同一个HARQ-ACK码本反馈HARQ-ACK对应的PDSCH接收或SPS release由第一DCI格式调度和第二DCI格式调度,且2的计数DAI比特位幂大于2的第一比特位幂和2的第二比特位幂的最大公约数时,第三计数DAI等于计数DAI对正整数M取模得到的数,或者,第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数。
3、在配置第一DCI格式和第二DCI格式,且计数DAI的比特位大于第一比特位和第二比特位中的最小值时,第三计数DAI等于计数DAI对正整数M取模得到的数,或者,第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数。
4、在配置第一DCI格式和第二DCI格式,且2的计数DAI比特位幂大于2的第一比特位幂和2的第二比特位幂的最大公约数时,第三计数DAI等于计数DAI对正整数M取模得到的数,或者,第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数。
需要说明的是,本申请实施例仅是以在上述情况下,第三计数DAI可以等于DCI中的计数DAI对正整数M取模得到的数,或者第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数为例进行说明。在另一实施例中,无论在何种情况下,第三计数DAI均等于DCI中的计数DAI对正整数M取模得到的数,或者,第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数。或者,当采用格式为DCI format 1_2的DCI调度时,第三计数DAI均等于DCI中的计数DAI对正整数M取模得到的数,或者,第三计数DAI等于取模数加y,取模数是计数DAI减y后对正整数M取模得到的数,y为非负整数。或者,当采用格式为DCI format 1_1的DCI调度时,直接采用指示信息的方式确定第三计数DAI。
步骤304,终端设备根据第三计数DAI确定DCI调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置。
当终端设备确定DCI中的计数DAI域的有效比特位后,根据该计数DAI域的比特位,确定第三计数DAI,再根据该第三计数DAI,确定DCI格式调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置。
本申请实施例提供的方法,终端设备接收DCI,根据DCI中的计数DAI域确定第三计数DAI,根据第三计数DAI确定DCI调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置。由于终端设备先根据计数DAI域确定了第三计数DAI,即使不同计数DAI域的比特位不同,也可以将根据计数DAI域转换为第三计数DAI,后续再根据第三计数DAI确定DCI调度的PDSCH接收或SPS release在一个HARQ-ACK码本反馈HARQ-ACK的位置,防止出现由于计数DAI的比特位不同导致确定的HARQ-ACK的位置错误的情况,保证了确定的HARQ-ACK的位置的准确性。
图3中的步骤304存在至少三种不同的计算方式,分别采用图4、图5和图6介绍如下:
在基于图3的可选实施例中,图4示出了本申请一个示例性实施例提供的DAI的指示方法的流程图。在本实施例中,步骤304可被替换实现为步骤4011-4013:
步骤4011,终端设备根据第三计数DAI确定第一计数DAI对应的第一翻转累计参数j_1和第二计数DAI对应的第二翻转累计参数j_2。
终端设备确定不同DCI中的计数DAI域的第一比特位或第二比特位后,根据第一比特位或第二比特位,即可确定不同的第三计数DAI,再根据第三计数DAI确定第一计数DAI对应的第一翻转累计参数j_1和第二计数DAI对应的第二翻转累计参数j_2。
步骤4012,当DCI格式为第一DCI格式时,终端设备根据第一计数DAI和第一翻转累计参数j_1,确定DCI调度的PDSCH接收或SPS release在HARQ-ACK码本反馈HARQ-ACK的位置。
在一种可能实现方式中,第一计数DAI域的第一比特位为1个比特,设置第三计数DAI为第一比特位的取值DAI_1,当第三计数DAI的取值大于前一次的第三计数DAI的取值时,将第一计数DAI对应的第一翻转累计参数j_1的取值加1,当第三计数DAI的取值不大于前一次的第三计数DAI的取值时,保持j_1不变,计算HARQ-ACK码本中的HARQ-ACK的位置为2*j_1+DAI_1。
DAI_1表示第一计数DAI域的第一比特位为1比特时的取值。可选地,该DAI_1由网络设备根据传输次数Y确定。例如,该DAI_1=Ymod2。当Y为2时,DAI_1为0。
步骤4013,当DCI格式为第二DCI格式时,终端设备根据第二计数DAI和第二翻转累计参数j_2,确定DCI调度的PDSCH接收或SPS release在HARQ-ACK码本反馈HARQ-ACK的位置。
在一种可能实现方式中,第二计数DAI域的第二比特位为2个比特,设置第三计数DAI为MOD(DAI_2,2),DAI_2为第二计数DAI域的第二比特位的取值,当出现两次第三计数DAI的取值大于前一次的第三计数DAI的取值时,将第二计数DAI域对应的第二翻转累计参数j_2 的取值加1;当不出现两次第三计数DAI的取值不大于前一次的DAI_e的取值时,保持j_2的取值不变,计算HARQ-ACK码本中的HARQ-ACK比特位编号为4*j_2+DAI_2。
其中,DAI_2为第二计数DAI域的第二比特位的取值,可选地,该DAI_2由网络设备根据传输次数Y确定。例如,该DAI_2=Ymod4。当Y为2时,DAI_2为2。
确定本次的j_2的取值后,再计算HARQ-ACK码本中的HARQ-ACK比特位编号为4*j_2+DAI_2。例如,j_2的取值为1,且DAI_2的取值为0,则确定HARQ-ACK比特位编号为4。
可选地,以表2为例,对图4所示的步骤进一步说明。

第三计数DAI 0 1 0 1 0 1 0
第二计数DAI对应的第二翻转累计参数j_2 0 0 0 0 1 1 1
第一计数DAI域对应的第一翻转累计参数j_1 0 0 1 1 2 2 3
HARQ-ACK的位置=4*j_2+DAI_2 0   2   4   6
HARQ-ACK的位置=2*j_1+DAI_1   1   3   5  
参见表2,在一个HARQ-ACK码本窗口中,包括7次PDSCH传输,当前的传输次数为0时,终端设备接收到的第一个DCI中的计数DAI域的比特位为2个比特,则确定计数DAI域的取值DAI_2为0,计算MOD(DAI_2,2)为0,确定第三计数DAI的取值为0,另外也不存在上一个第三计数DAI,则确定的j_2也为0,确定的HRAQ-ACK的位置为0。
当前的传输次数为1时,终端设备接收到的第二个DCI中的计数DAI域的比特位为1个比特,则确定计数DAI域的取值DAI_1为1,设置第三计数DAI与DAI_1相同,得到的第三计数DAI的取值为1,可选地,本次的第三计数DAI的取值不小于上一次的第三计数DAI的取值,因此确定j_1为0,j_2为0,计算得到的HRAQ-ACK的位置为1。
当前的传输次数为2时,终端设备接收到的第三个DCI中的计数DAI域的比特位为2个比特,则确定计数DAI域的取值DAI_2为2,计算MOD(DAI_2,2)为0,确定第三计数DAI的取值为0,且本次的第三计数DAI的取值小于上一次的第三计数DAI的取值,但第三计数DAI的取值仅有一次小于上一次的第三计数DAI的取值,确定的j_2为0,j_1为1,计算得到的HRAQ-ACK的位置为2。
当前的传输次数为3时,终端设备接收到的第四个DCI中的计数DAI域的比特位为1个比特,则确定计数DAI域的取值DAI_1为1,设置第三计数DAI与DAI_1相同,得到的第三计数DAI的取值为1,可选地,本次的第三计数DAI的取值不小于上一次的第三计数DAI的取值,因此确定j_1为1,j_2为0,计算得到的HRAQ-ACK的位置为3。
当前的传输次数为4时,终端设备接收到的第五个DCI中的计数DAI域的比特位为2个比特,则确定计数DAI域的取值DAI_2为0,计算MOD(DAI_2,2)为0,确定第三计数DAI的取值为0,且本次的第三计数DAI的取值小于上一次的第三计数DAI的取值,且第三计数DAI的取值有两次小于上一次的第三计数DAI的取值,确定的j_2为1,j_1为2,计算得到的HRAQ-ACK的位置为4。
当前的传输次数为5时,终端设备接收到的第六个DCI中的计数DAI域的比特位为1个比特,则确定计数DAI域的取值DAI_1为1,设置第三计数DAI与DAI_1相同,得到的第三计数DAI的取值为1,可选地,本次的第三计数DAI的取值不小于上一次的第三计数DAI的取值,因此确定j_1为2,j_2为0,计算得到的HRAQ-ACK的位置为5。
当前的传输次数为6时,终端设备接收到的第七个DCI中的计数DAI域的比特位为2个比特,则确定计数DAI域的取值DAI_2为2,计算MOD(DAI_2,2)为0,确定第三计数DAI 的取值为0,且本次的第三计数DAI的取值小于上一次的第三计数DAI的取值,且第三计数DAI的取值有一次小于上一次的第三计数DAI的取值,确定的j_2为1,j_1为3,计算得到的HRAQ-ACK的位置为6。
在一个HARQ-ACK码本窗口内,依次确定出的HARQ-ACK的位置分别为0,1,2,3,4,5,6,与PDSCH传输的位置编号相同。
需要说明的是,本申请实施例仅是以DAI_1、DAI_2、j_1、j_2为例进行说明,在另一实施例中,并不限于DAI_1、DAI_2、j_1、j_2,还可以采用其他方式对各个取值进行表示。
在基于图4的可选实施例中,图5示出了本申请一个示例性实施例提供的DAI的指示方法的流程图。在本实施例中,步骤4011可被替换实现为步骤5011-5012:
步骤5011,终端设备根据第三计数DAI确定翻转累计参数j_e。
步骤5012,终端设备根据第三计数DAI和翻转累计参数j_e,确定第一翻转累计参数j_1和第二翻转累计参数j_2。
在一种可能实现方式中,在第三计数DAI小于第三参数时,将翻转累计参数j_e累计增加。
其中,第三参数为正整数。例如该第三参数可以为1、2、3或者其他数值。
例如,当第三参数为2,第一次确定的第三计数DAI为1,小于第三参数,将翻转累计参数j_e累计增加,j_e为2,当第二次确定的第三计数DAI为4,大于第三参数,不将翻转累计参数j_e累计增加,j_e为1。
可选地,第三参数包括历史的第三计数DAI。
在每次确定第三计数DAI后,将前一次确定的第三计数DAI作为第三参数,将本次确定的第三计数DAI与前一次确定的第三计数DAI进行对比,确定本次确定的第三计数DAI是否小于前一次确定的第三计数DAI,从而确定是否将翻转累计参数j_e累计增加。
可选地,该第三参数还可以包括第三计数DAI的多个取值中的最大值。
例如,当确定了三个第三计数DAI后,分别为1、2、4,则将第三参数确定为第三计数DAI中的最大值4,后续将确定的每个第三计数DAI与第三参数4进行比较,确定每次的第三计数DAI是否小于第三参数,将翻转累计参数j_e累计增加。
在一种可能实现方式中,当第一计数DAI域的第一比特位为1个比特时,设置第三计数DAI为第一计数DAI域的第一比特位的取值DAI_1,当第三计数DAI的取值小于前一次的第三计数DAI的取值时,将翻转累计参数j_e的取值加1,当第三计数DAI的取值不小于前一次的第三计数DAI的取值时,保持j_e不变,设置第一计数DAI域对应的第一翻转累计参数j_1与j_e相同,计算HARQ-ACK码本中的HARQ-ACK的位置为2*j_1+DAI_1。
其中,DAI_1表示第一计数DAI域的第一比特位为1比特时的取值。可选地,该DAI_1由网络设备根据传输次数Y确定。例如,该DAI_1=Ymod2。当Y为2时,DAI_1为0。
例如,本次确定的第三计数DAI为0,前一次确定的第三计数DAI的取值为1,且前一次j_e为0时,则本次确定的j_e的取值为1。而当本次确定的第三计数DAI的取值不小于前一次确定的第三计数DAI的取值时,保持j_e的取值不变,也就是本次的j_e取值与上一次的j_e取值相同。
根据第三计数DAI确定翻转累计次数j_e后,设置j_1的取值与j_e相同。在此种情况下,即可根据确定的j_1和第一计数DAI域的第一比特位,计算HARQ-ACK码本中的HARQ-ACK的位置为2*j_1+DAI_1。
例如,当本次确定的j_1为1,DAI_1为1时,则确定HARQ-ACK的位置为3。
在另一种可能实现方式中,第二计数DAI域的第二比特位为2个比特,设置第三计数DAI为MOD(DAI_2,2),当第三计数DAI的取值小于前一次的第三计数DAI的取值时,将翻转累计参数j_e的取值加1,当第三计数DAI的取值不小于前一次的第三计数DAI的取值时,保持j_e不变,当j_e由奇数变为偶数,或者j_e的取值翻转两次时,将第二计数DAI域对应 的第二翻转累计参数j_2的取值加1,计算HARQ-ACK码本中的HARQ-ACK的位置为4*j_2+DAI_2。
其中,DAI_2为第二计数DAI域的第二比特位的取值,可选地,该DAI_2由网络设备根据传输次数Y确定。例如,该DAI_2=Ymod4。当Y为2时,DAI_2为2。
例如,当本次j_e的取值为2,而上一次的j_e的取值为1,且j_2的取值为1时,则确定将j_2的取值加1,得到j_2的取值为2。
确定本次的j_2的取值后,再计算HARQ-ACK码本中的HARQ-ACK的位置为4*j_2+DAI_2。例如,j_2的取值为1,且DAI_2的取值为0,则确定HARQ-ACK比特位编号为4。
可选地,以表3为例,对图5所示的步骤进一步说明。

当前的传输次数为3时,终端设备接收到的第四个DCI中的计数DAI域的比特位为1个比特,则确定计数DAI域的取值DAI_1为1,设置第三计数DAI与DAI_1相同,得到的第三计数DAI的取值为1,可选地,本次的第三计数DAI的取值不小于上一次的第三计数DAI的取值,因此确定j_e为0,设置j_1与j_e相同,则j_1的取值也为0,j_2的取值为0,计算得到的HRAQ-ACK的位置为3。
当前的传输次数为4时,终端设备接收到的第五个DCI中的计数DAI域的比特位为2个比特,则确定计数DAI域的取值DAI_2为0,计算MOD(DAI_2,2)为0,确定第三计数DAI的取值为0,且本次的第三计数DAI的取值小于上一次的第三计数DAI的取值,确定的j_e为2,另外本次的j_e从1变为2,确定j_2为1,j_1为2,确定的HRAQ-ACK的位置为4。

在一个HARQ-ACK码本窗口内,依次确定出的HARQ-ACK的比特位编号分别为0,1,2,3,4,5,6,与PDSCH传输的位置编号相同。
需要说明的是,本申请实施例仅是以j_e、DAI_1、DAI_2、j_1、j_2为例进行说明,在另一实施例中,并不限于j_e、DAI_1、DAI_2、j_1、j_2,还可以采用其他方式对各个取值进行表示。
在基于图3的可选实施例中,图6示出了本申请一个示例性实施例提供的DAI的指示方法的流程图。在本实施例中,步骤304可被替换实现为步骤6011-6012:
步骤6011,根据第三计数DAI确定翻转累计参数j_e。

其中,步骤6011的过程与上述步骤5011的过程类似,在此不再赘述。
步骤6012,根据第三计数DAI和翻转累计参数j_e,确定DCI调度的PDSCH接收或SPS release在HARQ-ACK码本反馈HARQ-ACK的位置。
在一种可能实现方式中,第一计数DAI域的第一比特位为1个比特,设置第三计数DAI为第一计数DAI域的有效比特位的取值DAI_1,当第三计数DAI的取值小于上一次的第三计数DAI的取值时,将j_e的取值加1,当第三计数DAI的取值不小于上一次的第三计数DAI的取值时,保持j_e的取值不变,计算HARQ-ACK码本中的HARQ-ACK的位置为X_e*j_e+DAI_e。
其中,X_e为第三计数DAI取值的个数。例如,该X_e可以为2的第一比特位幂和2的第二比特位幂的最大公约数。
在另一种可能实现方式中,第二计数DAI域的第二比特位为2个比特,设置第三计数DAI为MOD(DAI_2,2),DAI_2为第二计数DAI域的第二比特位的取值,当第三计数DAI的取值小于上一次的第三计数DAI的取值时,将j_e的取值加1,当第三计数DAI的取值不小于上一次的第三计数DAI的取值时,保持j_e的取值不变,计算HARQ-ACK码本中的HARQ-ACK的位置为X_e*j_e+DAI_e,
其中,X_e为第三计数DAI取值的个数。
以表4为例,对图6所示的步骤进一步说明。

当前的传输次数为4时,终端设备接收到的第五个DCI中的计数DAI域的比特位为2个比特,则确定计数DAI域的取值DAI_2为0,计算MOD(DAI_2,2)为0,确定第三计数DAI为0,且本次的第三计数DAI为0,小于上一次的第三计数DAI的取值1,将j_e的取值加1,得到的j_e的取值为2,则确定的HRAQ-ACK的位置为4。
当前的传输次数为5时,终端设备接收到的第六个DCI中的计数DAI域的比特位为1个比特,则确定计数DAI域的取值DAI_1为1,设置第三计数DAI与DAI_1相同,得到的第三计数DAI的取值为1,可选地,本次的第三计数DAI的取值不小于上一次的第三计数DAI的取值,确定j_e为2,则确定的HRAQ-ACK的位置为5。
当前的传输次数为6时,终端设备接收到的第七个DCI中的计数DAI域的比特位为2个比特,则确定计数DAI域的取值DAI_2为2,计算MOD(DAI_2,2)为0,确定第三计数DAI为0,且本次的第三计数DAI为0,小于上一次的第三计数DAI的取值1,将j_e的取值加1,得到的j_e的取值为3,则确定的HRAQ-ACK的位置为6。
在一个HARQ-ACK码本窗口内,依次确定出的HARQ-ACK的位置分别为0,1,2,3,4,5,6,与PDSCH传输的位置编号相同。

本申请还可以根据DCI中的总计DAI确定第三总计DAI,并且将第一计数DAI域的第一比特位替换为第一总计DAI的第三比特位,将第二计数DAI域的第二比特位替换为第二总计DAI的第四比特位,后续即可根据确定第三计数DAI的步骤,确定第三总计DAI。
可选地,该第三总计DAI可以等于DCI中的总计DAI,或者,该第三总计DAI可以等于DCI中的总计DAI对正整数M取模得到的数。
在一种可能实现方式中,正整数M为第三参数和第四参数中的最小值。

步骤701,网络设备发送DCI。
步骤702,终端设备接收DCI。
其中,该DCI中的计数DAI域的比特位为第一比特位。
网络设备向终端设备发送DCI,该DCI用于调度PDSCH接收或者SPS释放,终端设备接收到该DCI后,后续即可确定该DCI中的计数DAI域的第一比特位,确定该计数DAI域的取值。
步骤703,终端设备发送DCI调度的PDSCH接收或者SPS release的HARQ-ACK。
终端设备接收到DCI后,还需要向网络设备发送该DCI调度的PDSCH接收或者SPS release的HARQ-ACK,以供网络设备确定终端设备已成功接收到该DCI。
在一种可能实现方式中,在配置类型2的HARQ-ACK码本的情况下,不期望第一比特位等于0。
其中,该DCI的计数DAI域的第一比特位可以为0个比特、1个比特、2个比特或者其他数值,当在配置类型2的HARQ-ACK码本的情况下,终端设备不期望第一比特位等于0,以防止出现不可进行HARQ-ACK复用的情况。
可选地,不期望第一比特位等于0也说明第一比特位大于0,例如该第一比特位可以为1个比特、2个比特或者其他数值。
在另一种可能实现方式中,在配置类型2的HARQ-ACK codebook且第一比特位等于0的情况下,根据DCI确定HARQ-ACK的资源位置,在资源位置上发送PDSCH接收或者SPS  release对应的HARQ-ACK。
当DCI中的计数DAI域的比特位为0比特时,则终端设备确定不可进行HARQ-ACK复用,此时终端设备可以确定DCI对应的资源位置。
其中,该资源位置用于表示在传输信道中的时域位置和频域位置。
可选地,终端设备根据DCI中的PDCCHresource indicator和PDSCH-to-HARQ_feedback timing indicator确定PUCCH资源位置。
本申请实施例提供的方法,DCI中的计数DAI域的第一比特位为0比特,说明在DCI中不存在计数DAI域,此时终端设备接收到该DCI后,获取该DCI指示的资源位置,在该资源位置上传输HARQ-ACK,可以保证终端设备准确传输HARQ-ACK,保证了HARQ-ACK传输的准确性。
