Description

HARQ-ACK传输方法及装置、通信设备及存储介质 技术领域
本申请实施例涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及一种混合自动重传请求应答(Hybrid Automatic Repeat request acknowledgement，HARQ-ACK)传输方法及装置、通信设备及计算机存储介质。
背景技术
在相关技术中，基站在动态调度物理下行共享信道(Physical Downlink Shared Channel，PDSCH)资源时，需要为该PDSCH资源所传输下行数据指示对应的HARQ-ACK的反馈资源。调度该PDSCH资源中的下行控制信息(Down Control Information，DCI)中包含一个时域偏移量(K1)信息域和物理上行控制信道资源指示(Physical Uplink Control Channel resource indicator,PRI)信息域。
该K1信息域指示了传输HARQ-ACK的PUCCH资源所在的时隙(slot)与被调度PDSCH资源所在的时隙之间的间隔。
该PRI信息域指示了承载该HARQ-ACK的PUCCH资源ID。根据该DCI中的K1指示可以确定承载HARQ-ACK的PUCCH资源所在的时隙。
根据需要反馈HARQ-ACK比特数可以确定PUCCH资源集合的索引，即PUCCH资源集合ID。且由于HARQ-ACK比特数的多少是基站和UE都已经知道的共同信息，因而不需要在DCI中指示。
根据DCI中的PRI信息域可以确定在PUCCH资源集合中使用的PUCCH资源的索引，也即知道了承载HARQ-ACK的PUCCH资源ID。
在有一些情况下，联合承载该DCI的物理下行控制信道(Physical  Downlink Control Channel，PDCCH)资源来一起判断承载HARQ-ACK的PUCCH资源ID。
在相关技术中提出了一种半静态PDSCH调度方式，也叫半持续调度方式(Semi-Persistent Scheduling，SPS)。在该种方式下，基站使用无线资源控制(Radio Resource Control，RRC)层信令为该SPS周期配置一个K1信息域的K1值和PDSCH资源的SPS周期(以毫秒为单位)。
在激活SPS的PDSCH传输的DCI中包含PRI信息域以及PDSCH资源的时频域位置。在使用半持续调度的情况下，基站在发送激活SPS的PDSCH传输的DCI之后，即可在指定的PDSCH资源上周期的发送SPS PDSCH资源传输的下行数据，而不用发送调度该PDSCH资源的DCI。UE在收到激活SPS的PDSCH传输的DCI之后，就可以在按照该DCI指示，周期的接收基站在PDSCH信道上的下行数据，而不用尝试接收调度该PDSCH资源的DCI。

如图2所示，本实施例提供一种HARQ-ACK传输方法，其中，应用于UE中，包括：
S110：在配置使用一次性HARQ-ACK反馈机制且SPS的PDSCH传输被激活的情况下，在当前SPS周期的PDSCH资源所传输下行数据对应的HARQ进程号，是本轮HARQ进程号使用中HARQ进程号集合内最后一个未被使用的HARQ进程号时，触发所述一次性HARQ-ACK反馈；

在PDSCH资源的调度信息中可预先配置有半持续调度用于HARQ-ACK传输的配置信息，例如，该配置信息指定了HARQ进程号集合，在一个HARQ进程号集合中包括了多个可用于SPS PDSCH所传输数据的HARQ进程号。
例如，基站可以通过高层信令，例如，无线资源控制(Radio Resource Control，RRC)信令配置PDSCH资源。具体如，通过RRC信令配置了半持续调度的周期、半持续调度的HARQ进程数及半持续调度的HARQ进程号集合的其中之一；所述PDSCH资源所在的时隙的信息。

所述HARQ processes ID为前述HARQ进程号。所述CURRENT_slot为PDSCH资源所在时隙的编号；所述periodicity为以毫秒为单位的SPS周期，也即在半持续调度的传输中两个相邻的SPS次PDSCH传输之间的间隔；一个所述SPS周期包括一次SPS PDSCH传输。
所述numberOfSlotsPerFrame是一个无线帧中所包含的时隙数。SFN是无线帧的索引。nrofHARQ-Processes是可用于半持续调度的HARQ进程号集合中HARQ进程号的总个数。所述slot number in the frame是当前时隙在其所属的无线帧中的相对时隙索引。
PDSCH资源一旦完成配置，可以通过物理层信令进行激活，例如， 通过下行控制信息(Downlink Control Information，DCI)下发激活指示，则此时SPS的PDSCH传输被激活，会根据PDSCH资源进行下行数据传输。例如，所述激活DCI是以一种特殊的无线网络临时标识(Radio Network Temporary Identity，RNTI)，也即CS-RNTI，进行CRC加扰的。在另一些实施例中，该DCI还可携带有偏移值(offset)，该偏移值可为符号偏移值，该符号偏移值为在半持续调度的调度信令默认的起始符号的基础上，间隔等于所述符号偏移值之后的起始位置进行SPS的PDSCH传输。在本申请实施例中，若当前基站已经为终端配置了使用一次性HARQ-ACK反馈机制，且半持续调度SPS的PDSCH传输也被激活，即基于PDSCH资源在进行半持续调度传输，则会判断当前SPS周期的PDSCH资源所传输下行数据所对应的HARQ进程号是否是HARQ进程号集合中HARQ进程号在一轮HARQ进程号使用中最后一个未被使用的HARQ进程号，如果是，触发基于所述一次性HARQ-ACK反馈机制的HARQ-ACK传输。。在等于所述HARQ进程号集合内所包含的HARQ进程号的个数的SPS周期后，UE能够自动触发反馈HARQ-ACK信息，不需要额外的基站触发信令。
例如，在HARQ进程号集合中包含N个HARQ进程号，则可供连续的N个SPS周期的PDSCH传输的使用。在使用HARQ进程号集合内的HARQ进程号时，可以采用依次遍历的方式，若当前SPS周期的PDSCH传输使用的HARQ进程号已经是本轮使用中最后一个未被使用的HARQ进程号号时，则说明基站需要接收HARQ-ACK了。例如，N等于8的时候，则HARQ进程号集合中的HARQ进程号可为0到7；若按次序使用HARQ进程号，则若当前SPS周期的PDSCH传输所对应HARQ进程的HARQ进程号为7，则说明该HARQ进程号为本轮使用中最后一个未被使用的HARQ进程号。
在一轮HARQ进程号使用中HARQ进程号集合中的一个HARQ进程号仅能够被使用一次。若N等于16时，则HARQ进程号集合中包括的HARQ进程号可为0到15；每一个HARQ进程号仅允许对应SPS周期的PDSCH传输。
在一轮HARQ进程号使用中UE会遍历所述HARQ进程号集合中所有的HARQ进程号。
所述HARQ进程号中所有的HARQ进程号都可以被多轮循环使用。例如，在HARQ进程号集合中包括8个HARQ进程号，且分别是0到7时，则第1至第8个SPS周期的PDSCH传输所使用的HARQ进程号分别是0、1、2、3、4、5、6及7。第9至第16个SPS周期的PDSCH传输所使用的HARQ进程号也分别是0、1、2、3、4、5、6及7。
基于一次性HARQ-ACK反馈机制的HARQ-ACK上报UE会将HARQ进程号集合内所有HARQ进程号所对应的HARQ进程的HARQ-ACK一次性上报给基站。
这样，第一方面，实现了UE自动对一次性HARQ-ACK反馈机制的触发；第二方面，在基站无需下发专门的触发信令或触发比特的情况下，UE会自动实现HARQ-ACK反馈的触发，减少了触发信令的开销。
在一些实施例中，如图3所示，所述方法还包括：
S130：在所述当前SPS周期的PDSCH资源所传输下行数据对应的HARQ进程号，不是本轮HARQ进程号使用中HARQ进程号集合内最后一个未被使用的HARQ进程号时，不触发所述一次性HARQ-ACK机制的使用。
如果在HARQ进程号集合中对应于当前SPS周期的HARQ进程号并非是最后一个未使用的HARQ进程号，则本轮HARQ进程号使用中并没有使得所有的HARQ进程号都被使用了一次，就暂时不触发所述一次性 HARQ-ACK反馈机制，如此，会使得HARQ进程号集合中每一个HARQ进程号都被使用到，减少了有的HARQ进程号未被使用到导致的HARQ进程号的浪费。
在一些实施例中，如图4所示，所述方法还包括：
S101：接收激活所述SPS PDSCH传输的DCI；
S102：根据所述DCI激活所述SPS PDSCH传输；其中，所述DCI还包括：PRI信息域和时域偏移信息域；
S121：根据所述PRI信息域，确定传输所述HARQ-ACK的PUCCH资源；
S122：根据所述时域偏移信息域，确定所述当前SPS周期PDSCH资源与传输所述HARQ-ACK的PUCCH资源之间的时隙偏移量。
所述PRI信息域可包含PUCCH资源的索引。所述时域偏移(K1)信息域，K1信息域指示了PDSCH资源与发送HARQ-ACK的PUCCH资源之间的时隙偏移量；该时隙偏移量可为：间隔的时隙个数。
在一个时隙上可能配置有多个PUCCH资源集合，而每一个资源集合包含一个或多个PUCCH资源。根据所述HARQ-ACK所占用的比特数，确定所述PUCCH资源集合。如此，首先根据K1信息域确定出发送HARQ-ACK的时隙，然后根据一次性发送的多个HARQ-ACK所占用的比特数，确定选择该时隙上哪一个PUCCH资源集合，然后根据PRI信息域从选择的PUCCH资源集合中选择出发送所述HARQ-ACK的PUCCH资源。
在一些实施例中，所述方法还包括：
在所述当前SPS周期的PDSCH资源所传输下行数据对应的HARQ进程号为所述HARQ进程号集合内本轮使用最后一个未被使用的HAQR ID时，确定在下一SPS周期的PDSCH资源所传输下行数据对应的 HARQ进程号为所述HARQ进程号集合中第1个HARQ进程号。
即在本轮SPS PDSCH的HARQ-ACK尚未上报时，便下一轮的SPS周期就开始了，此时由于一轮HARQ进程号使用所对应的所有HARQ进程的HARQ-ACK使用同一个PUCCH资源上报，如此，基站可以根据传输HARQ-ACK的PUCCH资源确定各个HARQ-ACK所对应的一轮SPS PDSCH传输。
在HARQ进程号集合中的HARQ进程号是排序的，在一轮HARQ进程号使用中，可以按照HARQ进程号在HARQ进程号集合中的排序进行使用的。
在HARQ进程号集中的排序，可以是按照HARQ进程号所对应数值从小到大排序或从大到小排序，还可以是不按照HARQ进程号所对应数值的其他排序。
如图5所示，本实施例提供一种HARQ-ACK传输方法，其中，应用于基站中，包括：
S210：在配置使用一次性HARQ-ACK反馈机制且SPS的PDSCH传输被激活的情况下，在当前SPS周期的PDSCH资源上传输下行数据；
S220：在所述当前SPS周期的PDSCH资源所传输下行数据对应的HARQ进程号，是本轮HARQ进程号使用中HARQ进程号集合内最后一个未被使用的HARQ进程号时，接收基于所述一次性HARQ-ACK反馈机制一次性上报的HARQ进程号集合中所有HARQ进程号所对应HARQ进程的HARQ-ACK。
在本实施例中，基站通过高层信令为UE配置一次性HARQ-ACK反馈机制。在该一次性HARQ-ACK反馈机制被触发了之后，基站会到对应的PUCCH资源上接收HARQ进程号所对应HARQ进程的HARQ-ACK；如此，实现基站在不下发一次性HARQ-ACK反馈机制的触发比特的情况 下，实现了UE对一次性HARQ-ACK反馈机制的触发，具有信令开销小的特点。
S220：在所述当前SPS周期的PDSCH资源所传输下行数据对应的HARQ进程号，不是本轮HARQ进程号使用中HARQ进程号集合内最后一个未被使用的HARQ进程号时，暂缓基于一次性HARQ-ACK反馈机制所对应的HARQ-ACK的接收工作或接收预备工作。
所述当前SPS周期的PDSCH资源所传输下行数据对应的HARQ进程号，不是本轮HARQ进程号使用中HARQ进程号集合内最后一个未被使用的HARQ进程号HARQ进程，即在本轮HARQ进程号使用中，该HARQ进程号集合内还有其他未被使用的HARQ进程号。
在一些实施例中，如图6所示，所述方法还包括：
S200：下发激活所述SPS的PDSCH传输的DCI；其中，所述DCI还包括：PRI信息域和K1信息域；
S201：根据所述PRI信息域，确定传输所述HARQ-ACK的PUCCH资源；
S202：根据所述K1信息域，确定所述当前SPS周期的PDSCH资源与传输所述HARQ-ACK的PUCCH资源之间的时隙偏移量。
该DCI的下发可在所述步骤S210之前。通过DCI的下发触发了SPS的PDSCH传输。
该DCI内携带有K1信息域和PRI信息域，基于这两个信息域和HARQ进程号集合中所包含的HARQ进程号个数，可以确定出一旦一次性HARQ-ACK反馈机制被触发之后，传输HARQ-ACK的PUCCH资源。
在一些实施例中，所述方法还包括：
根据传输所述HARQ-ACK的PUCCH资源，确定具有相同HARQ 进程号的HARQ-ACK所对应的SPS周期。
由于一次性HARQ-ACK反馈机制，会一次性将所有HARQ进程的HARQ-ACK采用同一个PUCCH资源传输。不同PUCCH资源传输的HARQ-ACK是重复使用了相同的HARQ进程号，但是基站根据PUCCH资源和传输下行数据的PDSCH资源之间的时域偏移量，就能够区分使用相同HARQ进程号的不同SPS周期的HARQ-ACK，从而能够避免混淆。
如图7所示，本实施例提供一种HARQ-ACK传输的装置，其中，应用于中，包括：

在另一些实施例中，所述第一触发模块110及所述第一发送模块120可均为软硬结合模块；所述软硬结合模块可包括可编程阵列；所述可编程阵列包括但不限于：复杂可编程阵列和现场可编程阵列。
在还有一些实施例中，所述第一触发模块110及所述第一发送模块120可均为纯硬件模块，所述纯硬件模块至少包括专用集成电路。
在一些实施例中，所述第一触发模块110，还配置为在所述当前SPS周期的PDSCH资源所传输下行数据对应的HARQ进程号，不是本轮HARQ进程号使用中HARQ进程号集合内最后一个未被使用的HARQ进程号时，不触发所述一次性HARQ-ACK机制的使用。
在一些实施例中，所述装置还包括：
第一接收模块，被配置为接收激活所述SPS的PDSCH传输的下行控制信息DCI；
激活模块，被配置为根据所述DCI激活所述SPS PDSCH传输；其中，所述DCI还包括：物理上行控制信道PUCCH资源指示PRI信息域和时域偏移信息域；
第一确定模块，被配置为根据所述PRI信息域，确定传输所述HARQ-ACK的PUCCH资源；

第二发送模块210，被配置为在配置使用一次性HARQ-ACK反馈机制且半持续调度SPS的物理下行共享信道PDSCH传输被激活的情况下，在当前SPS周期的PDSCH资源上传输下行数据；
第二接收模块220，被配置为在所述当前SPS周期的PDSCH资源所传输下行数据对应的HARQ进程号，是本轮HARQ进程号使用中HARQ进程号集合内最后一个未被使用的HARQ进程号时，接收基于所述一次性HARQ-ACK反馈机制一次性上报的HARQ进程号集合中所有HARQ进程号所对应HARQ进程的HARQ-ACK。
在一些实施例中，所述第二发送模块210及所述第二接收发送模块可均为程序模块，这些程序模块被处理器执行后能够实现是下行数据的传输及HARQ-ACK的接收。
在另一些实施例中，所述第二发送模块210及所述第二接收发送模块可均为软硬结合模块；所述软硬结合模块可包括可编程阵列；所述可编程阵列包括但不限于：复杂可编程阵列和现场可编程阵列。
在还有一些实施例中，所述第二发送模块210及所述第二接收发送模块可均为纯硬件模块，所述纯硬件模块至少包括专用集成电路。
在一些实施例中，所述第二发送模块210，还被配置为下发激活所述SPS的PDSCH传输的下行控制信息DCI；其中，所述DCI用于激活所述SPS PDSCH传输；其中，所述DCI还包括：物理上行控制信道PUCCH资源指示PRI信息域和时域偏移信息域；
第三确定模块，被配置为根据所述PRI信息域，确定传输所述HARQ-ACK的PUCCH资源；
第四确定模块，被配置为根据所述时域偏移信息域，确定所述当前SPS周期的PDSCH资源与传输所述HARQ-ACK的PUCCH资源之间的时隙偏移量。
以下结合上述任意实施例提供两个具体示例：
示例1：
本发明提出了一种在非授权信道上，UE在被配置了一次性HARQ-ACK反馈的情况下，在基站进行PDSCH资源的半持续调度的情况下，基站触发UE进行一次性HARQ-ACK反馈的方法。
当UE被配置为使用一次性HARQ-ACK反馈机制传输HARQ-ACK，且UE被激活了SPS PDSCH传输的情况下，每当当前SPS周期的PDSCH资源对应的HARQ进程号已经单次的用尽为SPS PDSCH配置的HARQ进 程号的集合时，则UE触发一次性HARQ-ACK反馈机制。
在一次性HARQ-ACK反馈机制被触发之后，UE反馈所有下行HARQ进程的HARQ-ACK反馈信息。如果当前SPS周期PDSCH周期对应的HARQ进程号还没有单次的用尽为SPS PDSCH配置的HARQ进程号的集合，则不会触发UE的一次性HARQ-ACK反馈。
示例2：
基站为UE配一次性HARQ-ACK传输且UE被配置了SPS的PDSCH传输。SPS的PDSCH传输的HARQ进程号配置为0至4。
基站向UE发送第1、2及3个SPS周期的PDSCH资源所传输的下行数据。第1、2及3个SPS周期的HARQ进程号为0、1及2。
当基站给UE发送第4个SPS周期的PDSCH资源传输的下行数据时，第4个SPS周期对应的HARQ进程号为3，此时，已经单次用尽HARQ进程号集合中的所有HARQ进程号。
UE在接收到该SPS PDSCH资源传输的下行数据后，将触发一次性HARQ-ACK反馈机制。该一次性HARQ-ACK反馈机制所适用的PUCCH资源的确定方式如下：
根据携带SPS配置信息的DCI中K1信息域，可以确定承载HARQ-ACK的PUCCH资源所在的时隙；
根据需要反馈HARQ-ACK信息比特数的多少可以确定PUCCH资源集合的索引；即PUCCH资源集合索引。由于HARQ-ACK比特数是基站和UE都已经知道的共同信息，因而不需要在DCI中指示。该比特数可等于HARQ进程数。
根据携带SPS配置信息的DCI中的PRI信息域，可以确定在PUCCH资源集合中使用的PUCCH资源的索引，也即PUCCH资源ID。
当UE还没有发出HARQ-ACK时，第5个SPS周期的传输时刻已经到 了，这时基站可以继续在SPS的PDSCH资源上发送数据，对应的HARQ进程号为ID 0。这种行为并不会引起HARQ进程号的混淆，因为基站确定的知晓传输在某个PUCCH资源上的一次性HARQ-ACK反馈对应于哪些PDSCH资源传输的下行数据。
