在5G R17标准的IIoT(Industrial Internet of Things)/uRLLC(Ultra-reliable and low-latency communication)课题下，提出利用one-shot重传来用于取消的HARQ(Hybrid Automatic Repeat reQuest)反馈。然而，关于如何指示并确定初传HARQ与重传之间的时隙偏移并未提出有效方案。
为此，本公开提出了一种HARQ的时隙偏移的确定方法及装置、一种HARQ的时隙偏移的指示方法及装置，填补了现有技术中在采用one-shot重传进行HARQ反馈时如何指示并确定初传HARQ与重传之间的时隙偏移的技术空白，从而有助于利用one-shot(单发)重传进行HARQ反馈的实现。
下面结合附图对本申请所提供的HARQ的时隙偏移的确定方法及装置、HARQ的时隙偏移的指示方法及装置进行详细地介绍。
图2示出了根据本公开实施例的一种HARQ的时隙偏移的确定方法的流程示意图。如图2所示，该方法可由UE执行，且包括以下步骤。
S201，接收网络设备发送的下行链路控制信息(Downlink Control Information，DCI)。
该DCI中的一个或多个域被复用以携带初传HARQ与重传HARQ之间的时隙偏移信息。
在触发one-shot重传之后，DCI不再用于调度物理下行链路共享信道(Physical Downlink Shared Channel，PDSCH)数据，因此，DCI中未被使用的域可被用于指示初传HARQ与重传HARQ之间的时隙偏移。
在一些实施例中，时隙偏移信息按照预设复用优先级顺序携带在DCI中的一个或多个域中。
可以按照预设复用优先级顺序复用DCI中的一个多个域以携带该时隙偏移信息。例如，DCI中的用于携带该时隙偏移信息的一个或多个域分别具有不同的复用优先级。可以按照从高复用优先级至低复用优先级顺序来复用DCI中的一个或多个域或者可以按照从低复用优先级至高复用优先级顺序来复用DCI中的一个或多个域。例如，当按照高复用优先级至低复用优先级顺序来复用DCI中的一个或多个域时，可以先复用具有最高复用优先级的域，若该域中的可用比特数不足以携带该时隙偏移信息，则继续复用具有次复用高优先级的域，依次类推，具有最低复用优先级的域被最后复用。
在一些实施例中，一个或多个域包括第一传输块(Translation block，TB)的调制与编码策略(Modulation and coding scheme，MCS)域、第一TB的冗余版本(Redundancy Version，RV)域以及第一TB的新数据指示(New data indicator，NDI)域中的一个或多个；其中，第一TB为DCI所调度的多个TB中的第一个TB；其中，MCS域的复用优先级高于RV域的复用优先级，以及RV域的复用优先级高于NDI域的复用优先级。
在复用DCI中的一个或多个域以携带时隙偏移信息时，可用仅复用DCI所调度的多个TB中的第一个TB的MCS域、RV域以及NDI域中的一个或多个。在一些实施例中，该MCS域、RV域以及NDI域的复用优先级顺序依次从高至低。
例如，假设MCS域中的可用比特位包括M 1-M N1共N1个、RV域中的可用比特位包括R 1-R N2共N2个、以及NDI域中的可用比特位包括N 1-N N3共N3个，而时隙偏移信息需要占用的比特数为N4。在复用DCI中的一个或多个域以携带时隙偏移信息时，可以优先复用MCS域来携带时隙偏移信息，即将时隙偏移信息携带在MCS域中；如果MCS域中的比特位不够用，即N4>N1，则继续复用RV域，即将时隙偏移信息携带中MCS域以及RV域中，例如可以占用MCS域中的N1个比特位并占用RV域中的(N4-N1)个比特位；如果MCS域以及RV域中的比特位仍不够用，即N4>N1+N2，则继续复用NDI域，将时隙偏移信息携带中MCS域、RV域以及NDI域中，例如可以占用用MCS域中的N1个比特位、RV域中的N2个比特位以及NDI域中的(N4-N1-N2)个比特位。
可选地，对于所述一个或多个域中的每个被复用域，时隙偏移信息按照从低至高比特位的顺序携带在该域中。
在复用DCI中的某个域时，可以按照从低比特位至高比特位的顺序复用该域以携带时隙偏移信息。例如，基于以上示例，MCS域中的可用比特位从低至高分别为M 1、M 2……M N1，RV域中的可用比特位从低至高分别为R 1、R 2……R N2，以及NDI域中的可用比特位从低至高分别为N 1、N 2……N N3。在复用该MCS域来携带时隙偏移信息时，依次占用MCS域中的M 1、M 2……比特位直至最后占用M N1比特位；如果MCS域中的比特位不够用，则继续复用RV域，即依次占用RV域中的R 1、R 2……比特位。
在一些实施例中，一个或多个域中的每个被复用域中未被用于携带时隙偏移信息的比特位填充0。
继续参考上述示例，如果N4＝N1+2，表明需要占用MCS域中的N1个比特位并占用RV域中的2个比特位以携带时隙偏移信息，则RV域中剩余(N2-2)个比特位可被填充0。
S202，从DCI中获取占用预定比特数的时隙偏移信息，并基于时隙偏移信息确定初传HARQ与重传HARQ之间的时隙偏移。
在一些实施例中，预定比特数，即时隙偏移信息所占用比特数，可以为固定值或浮动范围值。
在一些实施例中，UE可以与网络设备预先约定时隙偏移信息所占用比特数。在另一实施例中，UE可以通过RRC配置消息确定时隙偏移信息所占用比特数。
在一些示例中，UE可以与网络设备预先约定时隙偏移信息所占用比特数为4比特，或者网络设备可以通过RRC配置消息指示时隙偏移信息所占用比特数为4比特。又例如，UE可以与网络设备预先约定时隙偏移信息所占用比特数为{2,4,6,8}中的一个值，而网络设备进一步通过RRC配置消息、MAC-CE信令或DCI来指示该具体值。
在另一些示例中，UE可以与网络设备预先约定时隙偏移信息所占用比特数为3-6比特，或者网络设备可以通过RRC配置消息指示时隙偏移信息所占用比特数为3-6比特。
UE在从网络设备接收到携带该时隙偏移信息的DCI后，可以按照预定比特数从该DCI中获取该时隙偏移信息，即UE可以预先确定该时隙偏移信息所占用比特数，并从该DCI中获取占用相应比特数的时隙偏移信息。UE可以基于该时隙偏移信息确定初传HARQ与重传HARQ之间的时隙偏移。
例如，假设UE预先确定时隙偏移信息所占用比特数为4比特，并且UE与网络设备预先约定按照从高复用优先级到低复用优先级顺序依次复用DCI中的第一个TB的MCS域、RV域以及NDI域来携带该时隙偏移信息。UE在接收到DCI后，可以依次从第一个TB的MCS域、RV域以及NDI域中的被复用域的被复用比特位获取4个比特的时隙偏移信息。
又例如，假设UE预先确定时隙偏移信息所占用比特数为3-6比特，并且UE与网络设备预先约定按照从高复用优先级到低复用优先级顺序依次复用DCI中的第一个TB的MCS域、RV域以及NDI域来携带该时隙偏移信息。UE在接收到DCI后，可以通过盲检测依次检测第一个TB的MCS域、RV域以及NDI域，以从这些域中的被复用域的被复用比特位来获取时隙偏移信息，例如，该MCS域中的所有比特位被复用，而RV域中的仅第一比特位被复用而其他比特位填充0，以及NDI域的所有比特位填充0，则从该MCS域的所有比特位以及RV域中的第一比特位获取该时隙偏移信息。
根据本公开实施例的HARQ的时隙偏移的确定方法，UE能够接收网络设备发送的DCI，该DCI中的一个或多个域被复用以携带初传HARQ与重传HARQ之间的时隙偏移信息；UE从该DCI中获取占用预定比特数的时隙偏移信息以确定初传HARQ与重传HARQ之间的时隙偏移，填补了现有技术中在采用one-shot重传进行HARQ反馈时如何确定初传HARQ与重传之间的时隙偏移的技术空白，从而有助于利用one-shot重传进行HARQ反馈的实现。
图3示出了根据本公开实施例的一种HARQ的时隙偏移的确定方法的流程示意图。如图3所示，该方法可由UE执行，且包括以下步骤。
S301，接收网络设备发送的DCI。
该DCI中的一个或多个域被复用以携带初传HARQ与重传HARQ之间的时隙偏移信息。
在一些实施例中，时隙偏移信息按照预设复用优先级顺序携带在DCI中的一个或多个域中。
在一些实施例中，一个或多个域包括第一TB的MCS域、第一TB的RV域以及第一TB的NDI域中的一个或多个；其中，第一TB为DCI所调度的多个TB中的第一个TB；其中，MCS域的复用优先级高于RV域的复用优先级，以及RV域的复用优先级高于NDI域的复用优先级。
在一些实施例中，对于所述一个或多个域中的每个被复用域，时隙偏移信息按照从低至高比特位的顺序携带在该域中。
在一些实施例中，一个或多个域中的每个被复用域中未被用于携带时隙偏移信息的比特位填充0。
关于上述步骤S301及其相关细节的详细描述，可以参考关于步骤S201及其相关细节的描述，在此不再赘诉。
S302，确定时隙偏移信息所占用比特数。
在一些实施例中，时隙偏移信息所占用比特数可以为固定值或浮动范围值。
例如，时隙偏移信息所占用比特数可以为4比特，或者时隙偏移信息所占用比特数可以为{2,4,6,8}中的一个值，或者时隙偏移信息所占用比特数可以为3-6比特。
在一些实施例中，上述步骤S302可以包括以下任意步骤：
S3021，基于预先约定信息确定时隙偏移信息所占用比特数。
在本实施例中，可以基于协议约定确定时隙偏移信息所占用比特数。例如，UE可以与网络设备预先约定时隙偏移信息所占用比特数，UE基于该预先约定确定时隙偏移信息所占用比特数。
S3022，基于网络设备发送的RRC配置消息确定时隙偏移信息所占用比特数。
在本实施例中，可以通过RRC配置消息来指示该时隙偏移信息所占用比特数。例如，网络设备可以向UE发送RRC配置消息，该RRC配置消息指示时隙偏移信息所占用比特数，从而UE可以根据该RRC配置消息确定时隙偏移信息所占用比特数。
S3023，基于预先约定信息确定时隙偏移信息所占用比特数的可选值集合，以及基于网络设备发送的RRC配置消息、MAC-CE信令或DCI从可选值集合中选择一个值作为时隙偏移信息所占用比特数。
在本实施例中，可以基于协议约定确定时隙偏移信息所占用比特数的可选值集合，然后基于网络设备发送的RRC配置消息、MAC-CE信令或DCI从该可选值集合中确定时隙偏移信息所占用比特数。
例如，UE可以与网络设备预先约定时隙偏移信息所占用比特数为{2,4,6,8}中的一个值，而网络设备进一步通过RRC配置消息、MAC-CE信令或DCI来指示该具体值。
S303，从DCI中获取相应占用比特数的时隙偏移信息，并基于时隙偏移信息确定初传HARQ与重传HARQ之间的时隙偏移。
关于上述步骤S303及其相关细节的详细描述，可以参考关于步骤S202及其相关细节的描述，在此不再赘诉。
应当注意的是，上述步骤S301-S303的执行顺序并非必须如上所述，而可以以其他顺序执行。例如，步骤S302可以与S301同时执行或在其之前执行。
根据本公开实施例的HARQ的时隙偏移的确定方法，UE能够接收网络设备发送的DCI，该DCI中的一个或多个域被复用以携带初传HARQ与重传HARQ之间的时隙偏移信息；UE从该DCI中获取占用预定比特数的时隙偏移信息以确定初传HARQ与重传HARQ之间的时隙偏移，填补了现有技术中在采用one-shot重传进行HARQ反馈时如何确定初传HARQ与重传之间的时隙偏移的技术空白，从而有助于利用one-shot重传进行HARQ反馈的实现。
图4示出了根据本公开实施例的一种HARQ的时隙偏移的指示方法的流程示意图。如图4所示，该方法可由网络设备执行，且包括以下步骤。
S401，向UE发送下行链路控制信息(Downlink Control Information，DCI)。
其中该DCI中的一个或多个域被复用以携带初传HARQ与重传HARQ之间的时隙偏移信息。
在触发one-shot重传之后，DCI不再用于调度物理下行链路共享信道(Physical Downlink Shared Channel，PDSCH)数据，因此，DCI中未被使用的域可被用于指示初传HARQ与重传HARQ之间的时隙偏移。
在一些实施例中，时隙偏移信息按照预设复用优先级顺序携带在DCI中的一个或多个域中。
可以按照预设复用优先级顺序复用DCI中的一个多个域以携带该时隙偏移信息。例如，DCI中的用于携带该时隙偏移信息的一个或多个域分别具有不同的复用优先级。可以按照从高复用优先级至低复用优先级顺序来复用DCI中的一个或多个域或者可以按照从低复用优先级至高复用优先级顺序来复用DCI中的一个或多个域。例如，当按照高复用优先级至低复用优先级顺序来复用DCI中的一个或多个域时，可以先复用具有最高复用优先级的域，若该域中的可用比特数不足以携带该时隙偏移信息，则继续复用具有次复用高优先级的域，依次类推，具有最低复用优先级的域被最后复用。
在一些实施例中，一个或多个域包括第一传输块(Translation block，TB)的调制与编码策略(Modulation and coding scheme，MCS)域、第一TB的冗余版本(Redundancy Version，RV)域以及第一TB的新数据指示(New data indicator，NDI)域中的一个或多个；其中，第一TB为DCI所调度的多个TB中的第一个TB；其中，MCS域的复用优先级高于RV域的复用优先级，以及RV域的复用优先级高于NDI域的复用优先级。
在复用DCI中的一个或多个域以携带时隙偏移信息时，可用仅复用DCI所调度的多个TB中的第一个TB的MCS域、RV域以及NDI域中的一个或多个。在一些实施例中，该MCS域、RV域以及NDI域的复用优先级顺序依次从高至低。
在一些实施例中，对于所述一个或多个域中的每个被复用域，时隙偏移信息按照从低至高比特位的顺序携带在该域中。
在复用DCI中的某个域时，可以按照从低比特位至高比特位的顺序复用该域以携带时隙偏移信息。
在一些实施例中，一个或多个域中的每个被复用域中未被用于携带时隙偏移信息的比特位填充0。
例如，假设该时隙偏移信息需要占用N4个比特位，DCI所调度的多个TB中的第一个TB的MCS域的可用比特数为N1个，RV域的可用比特数为N2个以及NDI域的可用比特数为N3个。如果N4＝N1+2，表明需要占用MCS域中的N1个比特位并占用RV域中的2个比特位以携带时隙偏移信息，则RV域中剩余(N2-2)个比特位可被填充0。
在一些实施例中，时隙偏移信息所占用比特数可以为固定值或浮动范围值。
例如，时隙偏移信息所占用比特数可以为4比特，或者时隙偏移信息所占用比特数可以为{2,4,6,8}中的一个值，或者时隙偏移信息所占用比特数可以为3-6比特。
