应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在第三代移动通信标准化组织(3rd Generation Partnership Project，3GPP)协议中，车联网具有两种传输模式：第一模式和第二模式。
第一模式：终端的传输资源是由网络例如基站gNB通过下行链路分配的，如图2A所示。终端根据基站分配的资源在侧行链路SL上进行数据的发送。基站可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。在LTE-V2X中又称为模式3。
第二模式：车载终端在资源池中选取一个资源进行数据的传输。在LTE-V2X中又称为模式4。如图2B所示，终端在网络内可以自己选取传输资源。此外，终端在网络外，也可以自己选取传输资源。
在NR-V2X中，需要支持自动驾驶，对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在LTE-V2X中，支持广播传输方式。在NR-V2X中，引入了单播和组播的传输方式。对于单播传 输，其接收端终端(简称接收端)只有一个终端，如图3所示，UE1、UE2之间进行单播传输。对于组播传输，其接收端是一个通信组内的所有终端，或者是在一定传输距离内的所有终端。如图4所示，UE1、UE2、UE3和UE4构成一个通信组，其中UE1发送数据，该组内的其他终端设备都是接收端。对于广播传输方式，其接收端是任意一个终端，如图5所示，其中UE1是发送端终端(简称发送端)，其周围的其他终端都是接收端。
下面介绍侧行配置授权(Configured Grant，CG)。
在NR-V2X中，支持模式1和模式2的资源分配方式。在模式2中，终端在资源池自主选取传输资源进行侧行传输，即上述第二模式。在模式1中，网络为终端分配侧行传输资源，即上述第一模式。具体的，网络可以通过动态调度(Dynamic Scheduling)的方式为终端分配侧行传输资源；或者网络可以为终端分配侧行配置授权(SL CG)传输资源。对于CG的资源分配方式，主要包括两种配置授权方式：type-1configured grant(第一类配置授权)和type-2configured grant(第二类配置授权)。
第一类配置授权：网络通过无线资源控制(Radio Resource Control，RRC)信令为终端配置侧行传输资源，该RRC信令配置包括时域资源、频域资源、解调用参考信号(Demodulation Reference Symbol，DMRS)、调制编码方案(Modulation and Coding Scheme，MCS)等在内的全部传输资源和传输参数。当UE接收到该高层参数后，可使用所配置的传输参数在配置的时频资源上进行侧行传输。
第二类配置授权：采用两步的资源配置方式，即RRC和下行控制信息(Downlink Control Information，DCI)的方式。首先，由RRC信令配置包括时频资源的周期、冗余版本、重传次数、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程数等在内的传输资源和传输参数。然后由DCI激活第二类配置授权的传输。并同时配置包括时域资源、频域资源等在内的其他传输资源和传输参数。UE在接收到RRC信令时，不能立即使用该高层参数配置的资源和参数进行侧行传输，而必须等接收到相应的DCI激活并配置其他资源和传输参数后，才能进行侧行传输。此外，网络可以通过DCI去激活该配置传输，当终端接收到去激活的DCI后，不能再使用该传输资源进行侧行传输。
如果网络为终端分配了配置授权的传输资源，当终端有侧行数据要传输时，可以直接使用该传输资源进行传输，而不需要向网络发送SR/BSR请求传输资源，从而降低时延。
在NR-V2X中，为了提高可靠性，引入了侧行反馈信道。例如，如图6A所示，对于单播传输，发送端向接收端发送侧行数据(例如包括物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)和物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH))；接收端向发送端发送HARQ反馈信息。发送端根据接收端的反馈信息判断是否需要进行重传。其中，HARQ反馈信息承载在侧行反馈信道例如物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)中。
可以通过预配置信息或者网络配置信息激活或者去激活侧行反馈。如果侧行反馈被激活，则接收端接收发送端发送的侧行数据，并且根据检测结果向发送端反馈HARQ肯定确认(Acknowledgement,ACK)或者否定确认(Negative Acknowledgement,NACK)。发送端根据接收端的反馈信息决定发送重传数据或者新数据。如果侧行反馈被去激活，接收端不需要发送反馈信息，发送端通常采用盲重传的方式发送数据。例如，发送端对每个侧行数据重复发送K次，而不是根据接收端反馈信息决定是否需要发送重传数据。
终端向网络上报侧行反馈信息的方式包括：
在模式1中，网络为终端分配侧行传输资源，如果发送端使用该资源传输支持侧行反馈的侧行数据，接收端向发送端发送侧行反馈信息。发送端将该侧行反馈信息上报给网络。网络根据该发送端上报的侧行反馈信息决定是否需要分配重传资源。
具体的，网络可以为终端分配物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源，该PUCCH传输资源用于承载发送端向网络上报的侧行反馈信息。
如图6B所示，例如：UE1是发送端(Transmisson，TX)UE，UE2是接收端(Reception，RX)UE。gNB为UE1分配侧行传输资源，并且分配了PUCCH的传输资源。UE1在gNB分配的侧行传输资源上向UE2发送侧行数据PSCCH/PSSCH。UE2根据侧行数据的检测结果向UE1发送侧行反馈信息 (如在PSFCH上发送HARQ-ACK)，该侧行反馈信息用于指示该侧行数据是否被正确接收。UE1将该侧行反馈信息通过PUCCH上报给网络。网络根据UE1上报的侧行反馈信息决定是否为UE1分配重传资源。
而对于侧行配置授权，在一个配置的资源周期内，只有一个PUCCH资源，用于终端向网络上报侧行反馈信息。如图7所示，例如：每个侧行配置授权的周期包括4个侧行传输资源，以及4个侧行反馈传输资源，1个PUCCH资源。该PUCCH资源在最后一个侧行反馈资源之后。TX UE在一个侧行配置授权的周期内只向网络上报一次侧行反馈信息，例如，只上报1比特的HARQ-ACK信息，用于指示该周期内传输的侧行数据是否被接收端正确接收。
为了降低PUCCH资源的开销，网络在为终端分配侧行传输资源时，可以为多次侧行传输的侧行反馈信息的上报分配相同的PUCCH资源。如图8所示，例如：网络通过DCI为终端分配第一个侧行资源用于传输PSSCH1，以及对应的PUCCH；并且为终端分配第二个侧行资源用于传输PSSCH2，该PSSCH2对应的上行传输资源也是该PUCCH。以此类推，四个PSSCH的侧行反馈信息都通过相同的PUCCH上报，因此终端可以通过一个PUCCH上报多个PSSCH对应的侧行反馈信息。
图9是根据本申请一实施例侧行反馈信息处理方法200的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S210、终端设备获取时间间隔集合，该时间间隔集合中的元素用于确定侧行反馈信道与上行传输信道之间的时间间隔；其中，该上行传输信道用于承载该终端设备向网络设备上报的侧行反馈信息。
S220、该终端设备根据该上行传输信道的时隙和该时间间隔集合，获取该上行传输信道承载的该侧行反馈信息。
可选地，在本申请实施例中，该时间间隔集合中包括至少一个时间间隔。
可选地，在本申请实施例中，该时间间隔集合中可以包括一个或多个元素，每个元素可以表示一个时间间隔。
可选地，在本申请实施例中，时间间隔集合中的元素可以为时隙数。示例性地，如果元素为3，可以表示侧行反馈信道与上行传输信道之间的时间间隔为3个时隙。时间间隔集合中的元素可以为一个或多个。例如，时间间隔集合中的元素可以为3，也可以{3,5}，或者为{2,6,10}等。此外，时间间隔集合中的元素也可以表示时间长度例如毫秒数，还可以表示时域符号数或者其他时间单元的数量。
终端设备根据时间间隔集合中的元素可以确定侧行反馈信道与上行传输信道之间的时间间隔，并且根据该上行传输信道的时隙与该时间间隔集合中的各时间间隔，确定侧行反馈信道所在的时隙。进一步地，根据侧行反馈信道所在的时隙确定该时隙对应的侧行数据信道所在的时隙，每个侧行数据信道对应一个或多个侧行反馈信息，从而可以获取该上行传输信道承载的需要向网络设备上报的侧行反馈信息。由于一个侧行反馈信道所在的时隙可以包括多个侧行反馈信道，每个侧行反馈信道包括一个或多个侧行反馈信息，可以在一个上行传输信道传输多个侧行反馈信息，降低所需的上行传输信道资源。
可选地，在本申请实施例中，该上行传输信道为PUCCH或PUSCH。
可选地，在本申请实施例中，侧行反馈信道为PSFCH。
可选地，在本申请实施例中，时间间隔集合中的元素可以用于确定PSFCH与PUCCH或PUSCH之间的时间间隔。
可选地，在本申请实施例中，该终端设备根据该上行传输信道的时隙和该时间间隔集合，获取该上行传输信道承载的该侧行反馈信息，包括：
该终端设备根据该上行传输信道的时隙和该时间间隔集合中的时间间隔，确定该侧行反馈信道所在的侧行时隙；
该终端设备根据该侧行反馈信道所在的侧行时隙，获取该上行传输信道承载的该侧行反馈信息。
在侧行链路中，一个侧行传输可以对应一个侧行反馈信息。多个侧行传输对应的侧行反馈信息可以在相同的时隙进行反馈，该时隙即为侧行反馈信道所在的时隙，在该时隙中可以传输多个侧行反馈信道，一个侧行反馈信道可以承载一个或多个侧行反馈信息。根据上行链路中，上行传输信道的时隙以及时间 间隔集合中的元素，可以确定侧行反馈信道在侧行链路中所在的侧行时隙。例如，如果时间间隔集合中只包括一个元素，根据该元素可以得到一个PSFCH所在的侧行时隙。如果时间间隔集合中包括M个元素，根据该M个元素可以得到M个PSFCH所在的侧行时隙。
从侧行反馈信道所在的侧行时隙可以获取其对应的侧行传输，每个侧行传输对应一个或多个侧行反馈信息。然后，可以通过上行传输信道承载所获取的这些侧行反馈信息，将该上行传输信道上报给网络。例如，从PSFCH所在的侧行时隙可以获取该侧行时隙对应的一个或多个侧行数据传输的时隙，进一步的，可以获取该一个或多个侧行数据传输对应的侧行反馈信息。然后，可以通过PUCCH或PUSCH承载所获取的这些侧行反馈信息，将该PUCCH或PUSCH上报给网络。
可选地，在本申请实施例中，该时间间隔集合中的元素所表示的时隙个数基于上行链路(Uplink，UL)子载波和/或侧行链路(SL)子载波的大小确定。
可选地，在本申请实施例中，该终端设备根据该上行传输信道的时隙和该时间间隔集合中的时间间隔，确定该侧行反馈信道所在的侧行时隙，包括：
对于该时间间隔集合中的每个时间间隔，该终端设备将该上行传输信道的时隙的索引减去该时间间隔，确定该侧行反馈信道所在的侧行时隙。
如果UL子载波和SL子载波的大小相同，UL和SL的时隙的索引一一对应。上行传输信道的时隙的索引减去时间间隔集合中的每个时间间隔可以得到上行时隙的索引，根据上行时隙的索引和侧行时隙的索引之间的对应关系，可以确定该上行时隙的索引对应的侧行时隙的索引，该侧行时隙的索引所表示的侧行时隙可以为该侧行反馈信道所在的侧行时隙。
例如，如果时间间隔集合中包括{n1、n2}，n1和n2表示时隙数。上行传输信道的时隙的索引为n，则可以计算得到：一个上行时隙的索引为n-n1，该上行时隙对应一个侧行时隙k1；另一个上行时隙的索引为n-n2，该上行时隙对应一个侧行时隙k2。其中，n1、n2可以为大于或等于1的正整数，n可以为大于n1和n2的正整数。如果n2大于n1，n2-n1可以为侧行链路的侧行反馈信道的周期N的整数倍，即该时间间隔集合中的元素之间的差值是侧行反馈信道的周期N的整数倍。

如果UL子载波和SL子载波的大小不同，UL和SL的时隙的索引不是一一对应的，例如，多个侧行时隙对应一个上行时隙。上行传输信道的时隙的索引减去时间间隔集合中的每个时间间隔可以得到上行时隙的索引。根据该上行时隙的索引可以得到其对应的多个侧行时隙的索引。在这些侧行时隙的索引所表示的侧行时隙中，可以确定出侧行反馈信道所在的侧行时隙。
例如，时间间隔集合中包括{n1、n2}，n1和n2表示时隙数。上行传输信道的时隙的索引为n，则可以计算得到：一个上行时隙的索引为n-n1，一个上行时隙的索引为n-n2。其中，n1、n2可以为大于或等于1的正整数，n可以为大于n1和n2的正整数。如果n2大于n1，n2-n1可以为侧行链路的侧行反馈信道的周期N的整数倍。n-n1所表示的上行时隙对应m1个侧行时隙。从这m1个侧行时隙中可以确定出侧行反馈信道所在的侧行时隙。这m1个侧行时隙中可能包括一个或多个侧行反馈信道所在的侧行时隙。类似地，n-n2所表示的上行时隙对应m2个侧行时隙。从这m2个侧行时隙中可以确定出侧行反馈信道所在的侧行时隙。这m2个侧行时隙中可能包括一个或多个侧行反馈信道所在的侧行时隙。

该终端设备根据该时间间隔集合中的元素个数和一个PSFCH时隙相关联的PSSCH时隙的个数，确定该上行传输信道承载的PSFCH的HARQ信息域的总数。
例如，PSFCH的周期为N，一个PSFCH时隙相关联的PSSCH时隙的个数也是N。如果每个PSSCH时隙对应一个侧行反馈信息，则这N个PSSCH时隙对应的侧行反馈信息的个数等于N。并且每个侧行反馈信息对应上行传输信道中承载的一个HARQ信息域。

可选地，在本申请实施例中，该方法还包括：如果在该N个PSSCH时隙中的一个时隙没有发送PSSCH，在进行比特与操作时，没有发送PSSCH的时隙对应的侧行反馈信息为ACK。例如：N等于4，4个PSSCH时隙中有三个的对应的侧行反馈信息分别为ACK、ACK、ACK，一个时隙没有发送PSSCH。将这个没有发送PSSCH的时隙对应的侧行反馈信息设置为ACK。比特与操作得到的侧行反馈信息为ACK。
再如，N等于6，6个PSSCH时隙中有三个对应的侧行反馈信息为ACK、NACK、NACK，三个时隙没有发送PSSCH，则将这三个没有发送PSSCH的时隙对应的侧行反馈信息设置为ACK。比特与操作得到的侧行反馈信息为NACK。
再如，N等于4，4个PSSCH时隙中有三个时隙发送了PSSCH，这三个时隙对应的侧行反馈信息为ACK、NACK、NACK，另一个时隙没有发送PSSCH，则将这三个时隙对应的侧行反馈信息进行比特与操作，得到的侧行反馈信息为NACK。
可选地，在本申请实施例中，在该上行传输信道关联的多个PSSCH时隙中传输相同侧行数据的情况下，该多个PSSCH时隙在该上行传输信道中对应的HARQ信息域为相同的HARQ状态。

本实施例的网络设备执行方法300的具体示例可以参见上述方法200的中关于网络设备例如基站的相关描述，为了简洁，在此不再赘述。
本申请实施例可以提供一种半静态HARQ-ACK码本设计，通过网络配置信息配置或者预配置的方式，可以配置多个侧行反馈信息通过一个PUCCH(或PUSCH)上报给网络。侧行传输资源和PUCCH(或PUSCH)的传输资源之间的对应关系可以通过半静态的方式配置。
实施例1：多个侧行传输对应的侧行反馈信息在一个PUCCH上复用。该实施例包括以下特征。
特征1：网络配置或者预配置一个时间间隔集合。该集合中的元素可以表示PSFCH所在的时隙和PUCCH所在的时隙之间的时隙偏移量。例如，该时隙偏移量用K1表示，该时隙偏移量根据上行的子载波确定，或者该时隙偏移量表示上行时隙的个数。
特征2：PUCCH中包括的HARQ信息域的个数，可以根据该集合中元素的个数确定。
例如，该集合中包括4个元素值，即4个候选的K1值，则PUCCH中包括的HARQ信息域的个数M是根据元素数4确定的。例如，HARQ信息域的个数M＝4；或者M＝4*N，其中，N表示PSFCH时域资源的周期参数。
特征3：PSFCH的时域周期是N个时隙。每N个时隙中包括1个PSFCH时隙，N个时隙中的每个PSSCH对应的侧行反馈信息都在这1个PSFCH时隙中传输。该N个时隙对应的侧行反馈信息可以通过下面的方式在PUCCH中上报至网络：
方式1：每个PSSCH时隙分别对应PUCCH的一个HARQ信息域；
方式2：每个PSFCH时隙分别对应PUCCH的一个HARQ信息域。每个PSFCH时隙关联多个PSSCH 时隙，例如，一个PSFCH时隙关联N个PSSCH时隙。可选地，终端根据该N个时隙中发送的PSSCH的优先级，选取优先级最高的PSSCH对应的侧行反馈信息上报。或者，可选地，终端根据该N个时隙中发送的PSSCH的先后顺序，选取最后发送的PSSCH对应的侧行反馈信息上报。或者，可选地，终端将该N个时隙中发送的PSSCH对应的侧行反馈信息绑定上报，其中，绑定操作可以包括将该N个时隙中发送的PSSCH对应的侧行反馈信息进行比特与操作。如果一个侧行反馈信息为一个HARQ-ACK信息，则可以将N个HARQ-ACK信息进行比特与操作。
例如，如图11所示，PSFCH的周期N＝4个时隙，即每4个时隙包括一个PSFCH时隙，并且每4个时隙的PSSCH传输对应的PSFCH在相同的时隙传输。如图11中的虚线箭头所示，时隙2、3、4、5对应的PSFCH都是在时隙7传输。PSFCH和PUCCH的时隙间隔的集合为{2,6}。如果网络调度时隙4的侧行传输，并且指示PSFCH和PUCCH之间的时间间隔K1＝2。由于在侧行时隙4传输PSSCH，该PSSCH对应的PSFCH在时隙7，并且PSFCH和PUCCH的时隙间隔K1＝2，即PUCCH所在的时隙为时隙9(时隙7加上时隙间隔2)。上述集合中的元素6表示时隙间隔K1＝6，根据该时隙间隔可以确定侧行时隙3(时隙9减去时隙间隔6)的PSFCH中的侧行反馈信息也是通过该PUCCH上报给网络。
由于网络可以分别调度终端在时隙2、3、4、5上发送侧行数据，因此，在这几个侧行时隙都有可能有对应的侧行反馈信息需要上报。如果时隙2、3、4、5对应相同的侧行反馈时隙，该时隙可以传输多个PSFCH，例如传输4个PSFCH，每个PSFCH分别包括1比特，并且分别对应时隙2、3、4、5对应的PSSCH的侧行反馈信息，这4个侧行PSSCH对应的侧行反馈信息可以都通过PUCCH上报。所以，在PUCCH中可以设置4个HARQ-ACK信息域，分别用于上报这4个时隙的侧行反馈信息。对于每个侧行时隙，在PUCCH中可以有一个HARQ-ACK信息域与之对应，用于承载该侧行时隙的PSSCH对应的侧行反馈信息。
通过以下方式可以确定一个PUCCH中承载的HARQ-ACK信息域的个数：
PUCCH所在的时隙为时隙n，根据集合中元素的取值确定该时隙n对应的PSFCH所在的时隙；如上例中，PUCCH所在的时隙为n＝9,根据集合{2,6}，确定PSFCH所在的时隙包括侧行时隙3(时隙9减去时隙间隔6)和时隙7(时隙9减去时隙间隔2)；
根据PSFCH的周期N，确定一个PSFCH时隙对应的PSSCH的时隙个数。每个PSSCH时隙对应PUCCH中的一个HARQ-ACK信息域。如上例中，N＝4，则在PUCCH中包括8个(N乘以时间间隔集合中的元素个数)HARQ-ACK信息域。
进一步的，根据每个PSSCH对应的侧行反馈信息的比特数，确定PUCCH承载的侧行反馈信息的总比特数大小。例如，一个PSSCH对应1比特侧行反馈信息，则上例中PUCCH包括8比特侧行反馈信息。
进一步的，PUCCH中HARQ-ACK信息域的个数和UL子载波和SL子载波的大小有关。图11中UL和SL的子载波间隔相同。图12中UL和SL的子载波间隔不同。例如UL SCS＝15kHz，SL SCS＝60kHz，即一个UL时隙对应4个SL时隙的长度。PSFCH的周期N＝2，PSFCH和PUCCH的时间间隔集合为{1,2}。
如果网络调度侧行传输，并且该侧行传输对应的侧行反馈信息通过UL时隙3的PUCCH上报，则该PUCCH中的HARQ-ACK码本信息如下确定：
集合中包括元素{1,2}，该元素表示的时隙个数是基于UL的时隙确定的。根据集合中的元素1，得到UL时隙2(即时隙3减去时隙间隔1)。由于该UL时隙2对应的SL时隙(侧行时隙8、9、10、11)中包括两个PSFCH时隙(侧行时隙9和侧行时隙11)。其中侧行时隙9的PSFCH对应侧行时隙6、7的PSSCH的侧行反馈，侧行时隙11的PSFCH对应侧行时隙8、9的PSSCH的侧行反馈。因此在PUCCH中包括4个HARQ-ACK信息域，前2比特对应侧行时隙6、7对应的侧行反馈信息，后2比特对应侧行时隙8、9对应的侧行反馈信息。类似的，根据集合中的元素2，得到UL时隙1(即时隙3减时隙间隔2)。UL时隙1对应的SL时隙(侧行时隙4、5、6、7)中包括两个PSFCH时隙(侧行时隙5和侧行时隙7)。其中侧行时隙5的PSFCH对应侧行时隙2、3的PSSCH的侧行反馈，侧行时隙7的PSFCH对应侧行时隙4、5的PSSCH的侧行反馈。在PUCCH中有另外4个HARQ-ACK信息域，前2比特对 应侧行时隙2、3对应的侧行反馈信息，后2比特对应侧行时隙4、5对应的侧行反馈信息。因此，该PUCCH中总共包括8个HARQ-ACK信息域，分别对应侧行时隙2至侧行时隙9对应的侧行反馈信息。
特征4：对于网络调度的多个PSSCH传输相同的侧行数据，则在PUCCH中，该多个PSSCH传输对应的HARQ-ACK信息域设置为相同的HARQ状态。
例如，参见图11，网络通过DCI为TX UE调度侧行时隙2、3上的传输资源，并指示PSFCH和PUCCH的时隙间隔是2。TX UE根据时隙2、3确定其对应的PSFCH为时隙7，因此可以确定PUCCH所在的时隙为时隙9。TX UE在时隙2、3上传输侧行数据的首次传输和重传。RX UE向TX UE发送侧行反馈信息ACK(或NACK)。TX UE在PUCCH中对应于侧行时隙2、3的两个HARQ-ACK信息域都设置为ACK(或NACK)。
另外，在上述各个实施例中，终端根据网络调度的多个PSSCH资源对应的最后一个PSFCH资源确定PUCCH所在的时隙。
例如，参见图11，网络调度SL中的时隙2和时隙8的侧行传输资源，并且指示PSFCH和PUCCH的时隙间隔是2，时隙2的PSSCH对应的PSFCH的时隙为时隙7，时隙8的PSSCH对应的PSFCH的时隙为时隙11。终端根据时隙11的PSFCH确定PUCCH的传输资源所在的时隙，即PUCCH传输资源位于时隙13(最后一个PSFCH的时隙11+时隙间隔2)。
进一步的，对于动态调度的资源分配方式，在DCI中会指示侧行传输资源，并且指示PSFCH和PUCCH之间的时隙间隔。根据侧行传输资源确定其对应的最后一个PSFCH所在的时隙。并且根据该时间间隔确定PUCCH的时隙，再根据网络配置的时间间隔集合中的所有K1的取值，确定该PUCCH承载的HARQ-ACK码本。对于type-1(或type-2)侧行配置授权，根据RRC信令(或DCI)配置侧行传输资源，并且在RRC信令(或DCI)中指示PSFCH和PUCCH之间的时间间隔。终端根据每个侧行配置授权周期中侧行传输资源确定其对应的最后一个PSFCH所在的时隙，并且根据该时间间隔确定PUCCH的时隙，再根据网络配置的定时参数集合中的所有K1的取值，确定该PUCCH承载的HARQ-ACK码本。
通过半静态的HARQ-ACK码本确定方法，使得多个侧行时隙对应的侧行反馈信息可以通过一个PUCCH上报给网络，降低PUCCH的资源开销。
