Description

反馈信息的发送方法、接收方法、装置、终端和介质 技术领域
本申请涉及移动通信领域，特别涉及一种反馈信息的发送方法、接收方法、装置、终端和介质。
背景技术
为了保障通信传输的可靠性，需要对传输的情况进行反馈。在移动通信中，基站以混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)方式将下行数据传输至终端。终端在接收到通过某个HARQ进程传输的下行数据后，需要向基站返回HARQ反馈信息，该HARQ反馈信息例如是ACK(表示正确接收)、NACK(表示未正确接收)。
HARQ进程在传输完一个数据块TB a后，又被调度传输新的数据块TB b。此时，终端只接收到数据块TB a而没有接收到数据块TB b。当进行该HARQ进程的HARQ反馈时，基站以为终端发送的是TB b对应的ACK/NACK反馈信息，而终端发送的其实是TBa对应的ACK/NACK反馈信息。相关技术中，通过下行控制信令DCI中的新数据指示(New Data Indicator,NDI)来避免上述理解歧义。NDI信息域相比前一次翻转，表示反馈的是新数据，如前一次是0，该次是1；NDI信息域与前一次相同，表示反馈的是重传数据，如前一次是0，该次是0。可选的，基站在触发进程反馈时进一步指示各HARQ进程对应的NDI信息，或者，终端在上报ACK/NACK信息时将每个进程的NDI信息一起上报给基站。
上述依靠NDI避免反馈信息理解歧义的方式中，每个HARQ进程都需要对应的NDI信息，传输的开销较大。

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。

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。
首先，对本申请实施例中涉及的名词进行简单介绍：
混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)：是一种将前向纠错编码(FEC)和自动重传请求(ARQ)相结合而形成的技术。在接收端使用FEC技术纠正所有错误中能够纠正的那一部分。通过错误检测判断不能纠正错误的数据包。丢弃不能纠错的数据包，向发射端请求重新发送相同的数据包。
全进程反馈方式：在基于HARQ进程的反馈方式中，终端支持最大N个HARQ进程。当接入网设备(例如，基站)触发终端进行全进程反馈时，不论终端实际收到多个HARQ进程，总是向接入网设备反馈N个进程对应的ACK/NACK反馈信息。ACK/NACK信息可以按 照HARQ进程的标识(或编号)顺序映射到反馈信息码本(codebook)中。未接收到的HARQ进程对应的ACK/NACK信息设置为占位信息(如NACK)。
以图1为例，假设终端最大支持8个HARQ进程，一个HARQ进程每次通过一个物理信道传输，每个HARQ进程对应独立的ACK/NACK反馈信息。终端接收到HARQ进程3、HARQ7、HARQ4。当接入网设备触发终端进行全进程反馈时，终端在PUCCH内传输反馈{NACK,NACK,NACK,bHARQ3,bHARQ4,NACK,NACK,bHARQ7}，其中bHARQi表示HARQ进程i对应的ACK/NACK反馈信息。终端未接收到的HARQ进程0、HARQ进程1、HARQ进程2、HARQ进程5和HARQ进程6对应的ACK/NACK信息设置为占位信息NACK。
基于指定反馈组的反馈方式：在基于HARQ进程的反馈方式中，HARQ进程通过反馈组内的物理信道传输反馈信息。当接入网设备(例如，基站)触发终端进行基于反馈组的进程反馈时，指示需要进行反馈的指定反馈组，终端向接入网设备上报指定反馈组内的HARQ进程对应的ACK/NACK反馈信息。
图2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13。
接入网12调度HARQ进程传输数据，终端13对HARQ进程进行信息反馈。
接入网12中包括若干个接入网设备120。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。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13提供无线通信功能的装置统称为接入网设备。
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，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13之间通过某种空口技术互相通信，例如Uu接口。
图3示出了本申请一个示例性实施例提供的反馈信息的传输方法的流程图，应用于如图2所示的终端和接入网设备中，该方法包括：
步骤301，接入网设备发送第一信令，第一信令中携带有N个新反馈指示信息，N个新反馈指与N个组一一对应，N为正整数；
第一信令是触发多个HARQ进程(全部或一组HARQ)同时反馈，且携带新反馈指示信息的信令。
可选的，接入网设备通过发送第一信令，触发终端进行多个HARQ进程的同时反馈。多个HARQ进程的同时反馈包括两种形式：全进程反馈，或，基于反馈组的HARQ进程反馈。
N个新反馈指示信息对应的N个组为反馈组，反馈组对物理信道进行划分。物理信道上承载HARQ进程。
可选的，一个反馈组中包括至少一个物理信道，当终端接收接入网设备发送的第一信令触发某一个反馈组时，将该反馈组内包括的物理信道上承载的HARQ进程的ACK/NACK反馈信息发送给接入网设备。
可选的，每个反馈组中包括的物理信道的数量是相同的或者不同的。
新反馈指示信息(New feedback information，NFI)的翻转用于指示该第一信令调度的物理信道所对应的反馈组内的ACK/NACK反馈信息被清除。
如图4所示，反馈组0对应NFI＝0的ACK/NACK通过PUCCH成功反馈之后，接入网设备可以在后续调度反馈组0的HARQ反馈时将NFI设置成1，NFI发生了翻转，表示反馈组0重新开始组织，即将之前NFI＝0对应的ACK/NACK反馈信息释放掉。
步骤302，终端接收第一信令；
终端接收第一信令后，对多个HARQ进程进行同时反馈。多个HARQ进程的同时反馈包括：全进程反馈，或者，对HARQ进程进行基于反馈组的进程反馈。
步骤303，终端生成反馈码本，反馈码本包括第一反馈信息，第一反馈信息对应第一HARQ进程，第一HARQ进程通过N个组中NFI的取值为第一取值的第一组内的物理信道传输，第一取值为N个NFI中与第一组对应的NFI的取值；
反馈码本是包含多个HARQ进程对应的反馈信息的码本。多个进程可以是终端支持的全部HARQ进程，也可以是对应指定反馈组的HARQ进程。
可选的，第一反馈信息包括：ACK和NACK中的一种。第一反馈信息是NACK时，意味着终端没有正确接收数据，接入网设备需要再次使用该反馈信息对应的第一HARQ进程重传数据；第一反馈信息是ACK时，意味着终端正确接收数据，接入网设备使用该反馈信息对应的第一HARQ进程传输新的数据。
第一取值是第一信令携带的N个NFI中与第一HARQ进程所属的第一组对应的NFI的取值。
需要说明的是，第一HARQ进程对应的第一组是N个组中的任意一组。
示意性的，第一HARQ进程通过N个组中的第一组内的物理信道传输。第一组对应的新反馈指示信息的取值为1，第一信令中指示的第一组的新反馈指示信息的取值也为1，则将第一HARQ的反馈信息包含在反馈码本中发送至接入网设备。
步骤304，终端将反馈码本发送至接入网设备；
步骤305，接入网设备接收反馈码本；
接入网设备通过接收到的反馈码本，得知每个HARQ进程的数据的反馈情况，确定是要重传数据还是传输新的数据。
综上所述，本实施例提供的方法，通过基于反馈组(简称组)的NFI信息，避免终端与接入网设备之间对反馈信息的理解歧义。终端支持的反馈组的数量小于支持的HARQ进程数，指示组的NFI信息的开销很小。另一方面，终端只需要传输ACK/NACK信息即可避免终端 与基站之间的理解歧义，上行控制信令开销也很小，提高了传输资源的利用效率。
在基于图3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反馈信息的发送的流程图，在本实施例中，图3中的步骤301之前还包括步骤306和步骤307：
步骤306，接入网设备发送第二信令，第二信令用于调度一个HARQ进程通过N个组中的一个组内的物理信道传输，且第二信令中携带组对应的NFI；
第二信令用于调度物理信道进行HARQ进程传输。
可选的，第二信令是下行控制信息(Downlink Control Information，DCI),DCI是物理下行控制信道(Physical Downlink Control Channel,PDCCH)上传输的与物理下行共享信道(Physical Downlink Share Channel,PDSCH)相关的控制信息。
可选的，第二信令的发送时间不晚于第一信令的发送时间。发送时间包括：发送的开始时间、发送的结束时间中的至少一种。
步骤307，终端接收第二信令；
终端通过接收第二信令，确定物理信道所属的反馈组，以及该反馈组对应的新反馈指示信息的取值。
在步骤302后，终端通过接收第一信令，确定第一HARQ进程的第一取值。只有第一HARQ进程的第二信令中携带的组对应的新反馈指示信息的取值与第一取值相同时，将该HARQ进程对应的反馈信息生成反馈码本。
在一个示例中，第一HARQ进程是通过P 1个组中的多个物理信道传输的HARQ进程，多个物理信道用于传输同一个HARQ进程；第一反馈信息是多个物理信道中时间在最后的物理信道中传输的第一HARQ进程对应的反馈信息，
其中，P 1个组的NFI的取值均为第一取值，P 1为不大于N的正整数。
第一HARQ进程是任意一个HARQ进程。或者说，第一HARQ进程是根据第一信令确定的需要上报反馈信息的多个HARQ进程中的一个。
可选的，多个物理信道中时间在最后的物理信道，包括：多个物理信道中结束时间在最后的物理信道；或，多个物理信道中起始时间在最后的物理信道。
示意性的，终端通过P 1个组中的2个物理信道传输的HARQ进程0，其中，P 1个组的NFI与HARQ进程0的所在的反馈组的第一取值相同，则第一反馈信息是2个物理信道中时间在后的物理信道中传输的HARQ进程0对应的反馈信息。
在一个示例中，反馈码本中还包括有第二反馈信息；第二反馈信息为第二HARQ进程对应的预设反馈信息，第二HARQ进程为终端在NFI的取值均为第二取值的P 2个组中未接收到的HARQ进程，第二取值为N个NFI中与P 2个组对应的NFI的取值；其中，第一取值和第二取值相同或不同,P 2为不大于N的正整数。
可选的，预设反馈信息为NACK。
在一个示例中，反馈码本中包括M个HARQ进程对应的反馈信息，M个HARQ进程包括所述第一HARQ进程；其中，M是配置给终端的最大HARQ进程数量，M为不小于N 的正整数。
M不小于N，即新反馈指示信息对应的组的数量小于或等于最大HARQ进程数量。
可选的，M个HARQ进程对应的反馈信息按照预设规则生成反馈码本。
可选的，预设规则包括但不限于：按照HARQ进程编号升序映射对应的反馈信息；未接收到的HARQ进程对应的反馈信息为NACK；第一反馈信息是多个物理信道中时间在最后的物理信道中传输的第一HARQ进程对应的反馈信息。
在一个示例中，第一信令包括：使用专用的无线网络临时标识(Radio Network Temporary Identity，RNTI)进行加扰的第一DCI；或，指定格式的第二DCI；或，使用指定的控制资源集合传输的第三DCI；或，使用指定的搜索空间传输的第四DCI；或，使用至少一个指定序列传输的信令，不同的指定序列得到的N个组对应的N个新反馈指示信息的取值不同；或，使用指定的物理资源传输的信令。
如表一所示，使用至少一个指定序列传输的信令时，接入网设备配置预先配置多个可用序列分别对应各组不同的NFI的取值。接入网设备根据本次实际的需求，选择多个序列中的一个发送给终端。如表1所示，假设终端最大支持2个组，每个反馈组对应的NFI有两种取值状态，则接入网设备需要预先配置4个序列。
表一
序列号 (组0的NFI，组1的NFI)
序列1 (0,0)
序列2 (0,1)
序列3 (1,0)
序列4 (1,1)
示意性的，如图6所示，配置给终端的最大HARQ进程数量为6，即终端最大支持6个HARQ进程。假设终端支持2个反馈组，即新反馈指示信息对应的组的数量为2：组0和组1。HARQ进程3和HARQ进程2通过组0内的物理信道传输。接着，HARQ进程1和HARQ进程0通过组1内的物理信道传输。接着，HARQ进程4和HARQ进程5通过组0内的物理信道传输。
根据第一信令指示组0的第二取值为1，组1的第二取值为0。根据第二信令，调度HARQ进程通过2个组中的一个组内的物理信道传输，且第二信令中携带组对应的新反馈指示信息的取值。在图6的前两次传输中组0的对应的新反馈指示信息的取值的是0，与第一信令指示组0对应的第二取值1不同；在图6的中间两次传输中组1的对应的新反馈指示信息的取值是0，与第一信令指示组1对应的第二取值0相同；在图6的后两次传输中组0的对应的新反馈指示信息的取值是1，与第一信令指示组0对应的第二取值1相同。只有HARQ进程的所在的组对应的新反馈指示信息的取值与第一信令指示的各个组的第二取值相同时，将该HARQ进程对应的反馈信息生成反馈码本。
按照HARQ进程编号升序映射对应的反馈信息，终端生成的反馈码本为{bHARQ0,bHARQ1,NACK,NACK,bHARQ4,bHARQ5}。其中bHARQ0为组1(NFI＝0)内的HARQ进程0的ACK/NACK反馈信息，bHARQ1为组1(NFI＝0)内的HARQ进程1的ACK/NACK反馈信息，bHARQ4为组0(NFI＝1)内的HARQ进程4的ACK/NACK反馈信息，bHARQ5为组0(NFI＝1)内的HARQ进程5的ACK/NACK反馈信息。
由于HARQ进程2和HARQ进程3所在的组0(NFI＝0)与第一信令指示的组0的第二取值的取值不同，终端在NFI的取值为第二取值的组(NFI＝1的组0以及NFI＝0的组1)中未接收到HARQ进程2和HARQ进程3，将这两个进程的反馈信息定义为NACK。
示意性的，如图7所示，配置给终端的最大HARQ进程数量为6，即终端最大支持6个HARQ进程。假设终端支持2个反馈组，即新反馈指示信息对应的组的数量为2：组0和组1。HARQ进程3和HARQ进程2通过组0内的物理信道传输。接着，HARQ进程1和HARQ进程0通过组1内的物理信道传输。接着，HARQ进程4和HARQ进程0通过组0内的物理信道传输。
根据第一信令指示组0的第二取值为1，组1的第二取值为0。根据第二信令，调度HARQ进程通过2个组中的一个组内的物理信道传输，且第二信令中携带组对应的新反馈指示信息的取值。在图7中的前2次传输中组0的对应的新反馈指示信息的取值是0，与第一信令指示组0对应的第二取值1不同；在图7中的中间2次传输时组1的对应的新反馈指示信息的取值是0，与第一信令指示组1对应的第二取值0相同；在图7中的候2次传输时组0的对应的新反馈指示信息的取值是1，与第一信令指示组0对应的第二取值1相同。只有HARQ进程的所在的组对应的新反馈指示信息的取值与第一信令指示的各个组的第二取值相同时，将该HARQ进程对应的反馈信息生成反馈码本。
按照HARQ进程编号升序映射对应的反馈信息，终端生成的反馈码本为{bHARQ0,bHARQ1,NACK,NACK,bHARQ4,NACK}。其中，bHARQ0为组0(NFI＝1)内的HARQ进程0的ACK/NACK反馈信息(相比与组1中的HARQ进程0，其传输时间在后)，bHARQ1为组1(NFI＝0)内的HARQ进程1的ACK/NACK反馈信息，bHARQ4为组0(NFI＝1)内的HARQ进程4的ACK/NACK反馈信息。
由于HARQ进程4和HARQ进程3所在的组0(NFI＝0)与第一信令指示的组0的第二取值不同，终端在NFI的取值为第二取值的组中未接收到HARQ进程4和HARQ进程3，将这两个进程的反馈信息定义为NACK。同时，终端未接收到的到HARQ进程5的反馈信息也被定义为NACK。
综上所述，本实施例提供的方法，通过基于反馈组(简称组)的NFI信息，避免终端与接入网设备之间对反馈信息的理解歧义。终端支持的反馈组的数量小于支持的HARQ进程数，指示组的NFI信息的开销很小。另一方面，终端只需要传输ACK/NACK信息即可避免终端与接入网设备之间的理解歧义，上行控制信令开销也很小，提高了传输资源的利用效率。
上述HARQ反馈支持两种形式：
第一：全进程反馈方式；
第二：基于指定反馈组的反馈方式。
针对上述第一种形式的HARQ进程反馈：
上述实施例中的反馈方式是全进程反馈，即终端接收到第一信令后，基于所有的HARQ进程的NF1，判断各个反馈组中需要反馈的HARQ反馈信息，反馈码本包括终端上支持的所有下行的HARQ进程的反馈信息。
如图6所示，配置给终端的最大的下行HARQ进程数量为6，即终端最大支持6个HARQ进程。终端支持两个反馈组：组0和组1。HARQ进程3和HARQ进程2通过组0内的物理信道传输。接着，HARQ进程1和HARQ进程0通过组1内的物理信道传输。接着，HARQ进程4和HARQ进程5通过组0内的物理信道传输。
根据第一信令指示组0的第二取值为1，组1的第二取值为0。终端生成的反馈码本为{bHARQ0,bHARQ1,NACK,NACK,bHARQ4,bHARQ5}。其中bHARQ0为组1(NFI＝0)内的HARQ进程0的ACK/NACK反馈信息，bHARQ1为组1(NFI＝0)内的HARQ进程1的ACK/NACK反馈信息，bHARQ4为组0(NFI＝1)内的HARQ进程4的ACK/NACK反馈信息，bHARQ5为组0(NFI＝1)内的HARQ进程5的ACK/NACK反馈信息。其中，由于HARQ进程2和HARQ进程3中的NFI与第一信令指示的NFI不同，则采用占位信息NACK填充。
针对上述第二种形式的HARQ进程反馈：
用于触发多个HARQ进程同时反馈的第一信令中，进一步还包括如下信息：
用于指示N个组中的P 3个组的指示信息；
其中，P 3个组是需要上报反馈信息的组，P 3不大于N。。也即，该P 3个组是指定的反馈组，需要终端向基站上报HARQ反馈信息的反馈组。
在一个示例中，反馈码本中包括第三HARQ进程对应的反馈信息；第三HARQ进程通过P 3个组中NFI的取值为第三取值的第二组内的物理信道传输，第三取值为N个NFI中与第二组对应的NFI的取值。以图7为例，假设第一信令包括用于指示组0和组1的指示信息，即组0和组1是需要上报反馈信息的组。其中，组0对应的第三取值为1，组1对应的第三取值为0。
由于组0和组1都被第一信令指示，则终端进行全HARQ进程反馈。终端生成的反馈码本为{bHARQ0,bHARQ1,NACK,NACK,bHARQ4,NACK}。其中，bHARQ0为组0(NFI＝1)内的HARQ进程0的ACK/NACK反馈信息，bHARQ1为组1(NFI＝0)内的HARQ进程1的ACK/NACK反馈信息，bHARQ4为组0(NFI＝1)内的HARQ进程4的ACK/NACK反馈信息，NACK为其他进程对应的占位信息。
而在另一种实现方式，假设第一信令包括用于指示组0的指示信息，即组0是需要上报反馈信息的组。其中，组0对应的第三取值为1。
由于只有组0被第一信令指示，则终端进行基于反馈组的反馈。终端生成的反馈码本为 {bHARQ4,bHARQ0}。其中，bHARQ0为组0(NFI＝1)内的HARQ进程0的ACK/NACK反馈信息，bHARQ4为组0(NFI＝1)内的HARQ进程4的ACK/NACK反馈信息。
综上所述，本实施例提供的方法，触发进程反馈的第一信令中包括组的指示信息，用于确定传输N个组中的哪些组对应的HARQ进程的反馈信息，将不符合条件的组内的HARQ进程不进行反馈，进一步节约了传输资源。
