下面对本申请实施例提供的同步资源配置方法、装置、用户设备及存储介质中涉及的一些概念和/或术语做一下解释说明。
1、载波聚合(CA)
载波聚合是将两个或更多的载波单元(CC)聚合在一起，以支持更大的传输带宽(例如最大为100MHz)。实际上每个载波单元对应一个独立的小区，通常可以将一个载波单元等同于一个小区。每个载波单元的最大带宽为20MHz。载波聚合支持不同载波单元之间的聚合：相同或不同带宽的载波单元、同一频带内邻接或非邻接的载波单元、不同频带内的载波单元。
2、sidelink(旁链路)
也可以称为副链路、侧链路或边链路等，用于UE之间不通过网络侧设备进行直接数据传输。
UE通过物理副链路控制信道(Physical Sidelink Control Channel，PSCCH)发送副链路控制信息(Sidelink Control Information，SCI)，调度物理副链路共享信道(Physical Sidelink Shared Channel，PSSCH)的传输以发送数据。该传输是以广播形式进行的，接收端并不向发送端反馈接收是否成功。
LTE sidelink支持两种资源分配模式，分别是调度资源分配(Scheduled resource allocation)模式与自主资源选择(autonomous resource selection)模式。前者由网络侧设备控制并为每个UE分配资源，后者由UE自主选择资源。
LTE支持sidelink载波聚合，LTE sidelink的CA与Uu接口(即downlink与uplink)不同，没有主载波(Primary component carrier，PCC)与辅载波(Secondary component carrier，SCC)之分。自主资源选择模式的UE在每个CC上独立进行资源感知(sensing)与资源预留。
LTE sidelink的设计适用于特定的公共安全事务(例如火灾或地震等灾难场所进行紧急通讯)，或车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如基本安全类通信、高级(自动)驾驶、编队、传感器扩展等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他高级V2X业务将通过NR sidelink支持。
5G NR系统可用于LTE所不支持的6GHz以上工作频段，支持更大的工作带宽，NR系统也支持终端之间直接通信的sidelink接口通信。
目前的sidelink传输主要分单播，组播，广播三种传输形式。单播是一对一(one to one)的传输，组播为一对多(one to many)的传输，广播也是一对多的传输，但是广播并没有UE属于同一个组的概念。
Sidelink上PSCCH承载SCI，SCI用于调度PSSCH。SCI中可以指示传输资源，并预留这些资源用于后续的传输。物理旁链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)用于反馈sidelink混合自动重传请求(Hybrid Automatic Repeat Request-Acknowledgment，HARQ-ACK)信息。UE确定sidelink HARQ信息后可以进一步地通过PUCCH或PUSCH将sidelink HARQ信息发送给基站。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的同步资源配置方法进行详细地说明。
本申请实施例可以应用于sidelink载波聚合场景，通过配置特定的同步参数，和/或对S-SSB进行分组处理，引入间隔参数等方式，能够在多个CC进行CA时使各个CC上同步资源对齐，避免同步资源在时域占用率较高(即资源利用率低)，以及同步信号与其他信号间传输冲突的问题，从而提升资源利用率，保障sidelink业务的可靠性。
本申请实施例提供一种同步资源配置方法，图2示出了本申请实施例提供的一种同步资源配置方法的流程图。如图2所示，本申请实施例提供的同步资源配置方法可以包括下述的步骤201和步骤202。

需要说明的是，UE仅选出一个载波作为第一载波，如果同时有多个载波满足上述第一载波的选择条件，则取决于UE实现，例如UE从该多个载波中随机选择一个载波作为第一载波。
可选地，本申请实施例中，上述目标时间的起点包括第一载波上目标时间的起点和其他载波上目标时间的起点，其他载波上目标时间的起点由第一距离获得，第一距离为其他载波上目标时间的起点与第一位置的距离，第一距离由第二距离确定，第二距离为第一载波上目标时间的起点与第一位置的距离。其中，第一位置为以下任一项：载波上直接帧号0(Direct Frame Number，DFN0)/系统帧号0(System Frame Number，SFN0)的位置、载波上同步周期的起点、载波上同步周期的终点。

Figure PCTCN2022088217-appb-000001
u 1为第一载波对应的子载波间隔因子，u i为载波i对应的子载波间隔因子。
需要说明的是，各个载波的offset在时域上的绝对长度相等，但由于各个载波的SCS可能不同，所以各offset具体的数值可能不同。
可选地，本申请实施例中，offsetstart 1等于第一载波上的第一位置与第一载波上第一时间的起点的距离。
可选地，本申请实施例中，上述目标时间的终点包括第一载波上目标时间的终点和其他载波上目标时间的终点，该其他载波上目标时间的终点由第三距离获得，该第三距离为其他载波上目标时间的终点与第一位置的距离，该第三距离由第四距离确定，该第四距离为第一载波上目标时间的终点与第一位置的距离。
可选地，本申请实施例中，针对目标时间的终点，UE可以根据网络侧设备配置、预配置、其他用户设备指示或UE自主行决定，获取第一载波上的第一位置(即第一载波上DFN0的位置/SFN0的位置/同步周期的起点/同步周期的终点)与第一载波上目标时间的终点的距离(即第四距离，可以称为offsetend 1)，并根据offsetend 1，计算得到其他载波上的第一位置(即其他载波上DFN0的位置/SFN0的位置/同步周期的起点/同步周期的终点)与该其他载波上目标时间的终点的距离(即第三距离，可以称为offsetend i)，其中，
Figure PCTCN2022088217-appb-000002
u 1为第一载波对应的子载波间隔因子，u i为载波i对应的子载波间隔因子。
需要说明的是，各个载波的offset在时域上的绝对长度相等，但由于各个载波的SCS可能不同，所以各offset具体 的数值可能不同。
可选地，本申请实施例中，offsetend 1等于第一载波上的第一位置与第一载波上第一时间的终点的距离。
可选地，本申请实施例中，上述目标时间的SCS满足以下任一项：与第一载波上第一时间的SCS相同、每个载波上目标时间的SCS分别与各自载波上第一时间的SCS相同、与所有载波中最大的SCS相同、与所有载波中最小的SCS相同、为预设SCS。
可以理解，各个载波上目标时间的SCS与第一载波上第一时间的SCS相同；或者，各个载波上目标时间的SCS与各自载波上第一时间的SCS相同，例如载波1上目标时间的SCS与载波1上第一时间的SCS相同，且载波2上目标时间的SCS与载波2上第一时间的SCS相同；或者，各个载波上目标时间的SCS与所有载波中最大的SCS相同；或者，各个载波上目标时间的SCS与所有载波中最小的SCS相同；或者，各个载波上目标时间的SCS为预设值。
可选地，本申请实施例中，上述目标间隔信息由以下至少一项确定：特定间隔信息、同步资源的分组信息、公共间隔信息、参考间隔信息、载波的SCS。
可选地，本申请实施例中，上述特定间隔信息包括以下至少一项：

传输周期内仅有一个目标时间；
目标时间的间隔不存在；
S-SSB组的间隔不存在；
S-SSB组内S-SSB的间隔不存在；
S-SSB组数为1。
需要说明的是，本申请实施例所述的间隔(即interval，例如下述实施例所述的interval1、interval2、interval3)不存在可以理解为：当一个周期内只有一个目标时间，或只有一个S-SSB/S-SSB组时，没有‘间隔’这个概念。因此也可以将间隔配置为指定值，例如间隔为0。
可以理解，UE可以通过网络侧设备配置、预配置、其他用户设备指示或UE自主决定，使传输同步信号的载波一个周期内都只传输一个S-SSB，和/或使每个同步资源内S-SSB的数量为1，和/或使得周期内只有一个目标时间，和/或使目标时间的间隔(可以称为interval1)不存在，和/或使S-SSB组的间隔(可以称为interval2)不存在，和/或使S-SSB组内S-SSB的间隔(可以称为interval3)不存在，和/或使S-SSB组数(syncgroupnum)为1。
示例性地，如图3所示，载波1、载波2和载波3进行CA，假设同步周期为160ms，载波1的SCS＝15kHz，载波2的SCS＝30kHz，载波3的SCS＝60kHz，配置每个载波的同步周期内传输的S-SSB数量均为1。UE设置目标时间的长度为各个载波上最长的第一时间，此时各个载波上的interval、interval2和interval3均不存在，各个载波每个同步周期内S-SSB的组数为1。
可选地，本申请实施例中，在第一情况下，上述目标间隔信息满足以下至少一项：
目标时间的间隔不存在；
S-SSB组的间隔不存在；
S-SSB组内S-SSB的间隔满足：一个周期内传输一个S-SSB的载波上S-SSB组内S-SSB的间隔不存在，或者一个周期内传输多个S-SSB的载波上S-SSB组内S-SSB的间隔为0(即将一个周期内的S-SSB配置在连续的slot上)。
其中，上述第一情况满足：同步资源的分组信息用于指示在存在至少两个载波在一个周期内传输多个S-SSB时，每个载波在一个周期内传输的S-SSB组数配置为1。
可以理解，在这种方式中，当存在至少两个载波在一个周期内传输多个S-SSB时，UE使每个载波在一个周期内传输的S-SSB组数为1，此时目标间隔信息满足上述至少一项。
示例性地，如图4所示，载波1、载波2和载波3进行CA，假设同步周期为160ms，载波1的SCS＝15kHz，载波2的SCS＝30kHz，载波3的SCS＝60kHz，载波1、载波2和载波3的同步周期内传输的S-SSB数量分别被配置为1、2和2。UE设置目标时间的长度为各个载波上最长的第一时间，此时各个载波上的interval1均不存在，各个载波上的interval2均不存在，载波1上的interval3不存在，载波2和载波3上的interval3＝0，各个载波每个同步周期内S-SSB的组数为1。
可选地，本申请实施例中，在第二情况下，上述目标间隔信息满足以下至少一项：
目标时间的间隔满足：若至少两个载波中存在一个周期内仅传输一个S-SSB的载波，则目标时间的间隔不存在；或者，若不存在一个周期内仅传输一个S-SSB的载波，则目标时间的间隔由网络侧设备配置、预配置、预定义、所述UE自主决定或其他UE指示；
S-SSB组的间隔满足：若至少两个载波中存在一个周期内仅传输一个S-SSB的载波，则S-SSB组的间隔不存在；或者，若不存在一个周期内仅传输一个S-SSB的载波，则S-SSB组的间隔与目标时间的间隔相同(即interval2＝interval1)；
S-SSB组内S-SSB的间隔满足：若至少两个载波中存在一个周期内仅传输一个S-SSB的载波，则一个周期内仅传输 一个S-SSB的载波上S-SSB组内S-SSB的间隔不存在，或者一个周期内传输多个S-SSB的载波上S-SSB组内S-SSB的间隔为0；若不存在一个周期内仅传输一个S-SSB的载波，则每个载波上S-SSB组内S-SSB的间隔为0(即将一个S-SSB组内的S-SSB配置在连续的slot上)；
S-SSB组内S-SSB的个数满足：任意载波(例如载波i)上每个S-SSB组包含的S-SSB个数为该任意载波在一个周期内传输的S-SSB个数与S-SSB组数的比值。
其中，上述第二情况满足：同步资源的分组信息用于指示在存在至少两个载波在一个周期内传输多个S-SSB时，每个载波在一个周期内传输的S-SSB组数配置为第一数值，该第一数值为第三载波上一个周期内传输的S-SSB的个数，该第三载波为一个周期内传输的S-SSB的个数最小的载波。
可选地，本申请实施例中，在第二情况下，目标间隔信息满足以下至少一项：
目标时间的间隔满足：若至少两个载波中的某个载波在一个周期内仅传输一个S-SSB，则目标时间的间隔不存在；或者，若至少两个载波中每个载波在一个周期内均传输多个S-SSB，则目标时间的间隔由网络侧设备配置、预配置、预定义、UE自主决定或其他UE指示；
S-SSB组的间隔满足：若至少两个载波的某个载波在一个周期内仅传输一个S-SSB，则S-SSB组的间隔不存在；或者，若至少两个载波中每个载波在一个周期内传输多个S-SSB，则S-SSB组的间隔与目标时间的间隔相同；
S-SSB组内S-SSB的间隔满足：若至少两个载波的某个载波在一个周期内仅传输一个S-SSB，则一个周期内仅传输一个S-SSB的载波上S-SSB组内S-SSB的间隔不存在，或者一个周期内传输多个S-SSB的载波上S-SSB组内S-SSB的间隔为0；若至少两个载波中每个载波在一个周期内传输多个S-SSB，则每个载波上S-SSB组内S-SSB的间隔为0；
S-SSB组内S-SSB的个数满足：任意载波上每个S-SSB组包含的S-SSB个数为任意载波在一个周期内传输的S-SSB个数与S-SSB组数的比值。
可以理解，在这种方式中，当存在至少两个载波在一个周期内传输多个S-SSB时，UE使每个载波在一个周期内传输的S-SSB组数为第一数值(可以称为min L i)，L i为载波i上的一个周期内传输的S-SSB个数，此时目标间隔信息满足上述至少一项。
示例性地，如图5所示，载波1、载波2和载波3进行CA，假设同步周期为160ms，载波1的SCS＝30kHz，载波2的SCS＝60kHz，载波3的SCS＝60kHz，载波1、载波2和载波3的同步周期内传输的S-SSB数量分别被配置为2、4和8。UE设置目标时间的长度为各个载波上最长的第一时间，此时每个载波在一个周期内传输的S-SSB组数＝＝2，各个载波上的interval1＝interval2，各个载波上的interval3均为0，载波1上每个S-SSB组内S-SSB的个数＝1，载波2上每个S-SSB组内S-SSB的个数＝2，载波3上每个S-SSB组内S-SSB的个数＝4。
本申请实施例中，UE可以通过特定的S-SSB配置或对S-SSB进行分组，保证各个载波上的同步资源对齐，此时任何载波无需丢弃S-SSB或发送虚拟S-SSB(例如对应位置为填充信息)。
可选地，本申请实施例中，上述目标间隔信息由公共间隔信息确定，包括：公共间隔信息由网络侧设备配置、预配置、预定义、其他用户设备指示或UE自主决定，至少两个载波的间隔信息与公共间隔信息相同。
可以理解，UE可以通过上述方式获取公共间隔信息，并设置至少两个载波的间隔信息与公共间隔信息相同。
可选地，本申请实施例中，UE可以将第一载波的间隔信息作为公共(common)间隔信息，该公共间隔信息包括以下至少一项：S-SSB的SCS、S-SSB个数、S-SSB组数、目标时间的间隔、S-SSB的间隔(例如S-SSB组的间隔interval2、S-SSB组内S-SSB的间隔interval3)。
示例性地，如图6所示，载波1、载波2和载波3进行CA，假设同步周期为160ms，载波1的SCS＝15kHz，载波2的SCS＝30kHz，载波3的SCS＝60kHz，载波1、载波2和载波3的同步周期内传输的S-SSB数量的原始配置分别为2、2和1。UE选择载波2为第一载波，并将载波2的间隔信息作为公共间隔信息，并设置各个载波上的间隔信息和公共间隔信息相同，因此载波1和载波3的同步周期内传输的S-SSB数量均变为2，S-SSB的SCS也变为30kHz，此时各个载波的同步资源保持对齐(此时可以无需采用目标时间保证同步资源对齐)。
本申请实施例中，UE可以通过网络侧设备配置、预配置、其它用户设备指示或UE自主决定，获取公共间隔信息(即公共S-SSB/S-SSB组配置)，应用于所有载波，此时各个载波上S-SSB的配置(例如个数和间隔等信息)相同，从而保证各个载波上的同步资源对齐。
可选地，本申请实施例中，上述目标间隔信息由参考间隔信息确定，包括以下至少一项：
在第四载波待传输的同步资源中存在第一同步资源时，第一同步资源或所有同步资源不传输；第一同步资源为不处于由参考间隔信息确定的时间内的同步资源；
在第五载波上存在第二时间、且第二时间与由参考间隔信息确定的时间对齐时，第二时间传输的信息为填充信息或特定信息；第二时间为所述第五载波上不传输同步资源的时间。
可以理解，若第四载波待传输的同步资源中存在第一同步资源，则UE不传输第一同步资源，或不传输所有同步资源；和/或，若第五载波上存在第二时间、且第二时间与由参考间隔信息确定的时间对齐，则UE在第二时间传输填充信息或特定信息。
可选地，本申请实施例中，UE可以将第一载波的间隔信息作为参考(reference)间隔信息，该参考间隔信息包括以下至少一项：S-SSB的SCS、S-SSB个数、S-SSB组数、目标时间的间隔、S-SSB的间隔(例如S-SSB组的间隔interval2、S-SSB组内S-SSB的间隔interval3)。
可以理解，一种方式，对于任意载波，若该任意载波存在需要传输的S-SSB/S-SSB组(即第一同步资源)，与由参考间隔信息确定的S-SSB/S-SSB组不处于相同时间(例如目标时间)，则UE不传输第一同步资源或不传输所有的S-SSB/S-SSB组。
示例性地，如图7所示，载波1和载波2进行CA，假设同步周期为160ms，载波1的SCS＝30kHz，载波2的SCS＝60kHz，载波1和2的同步周期内传输的S-SSB数量的原始配置分别为1和2。UE将载波1上的第一时间作为目标时间，并将载波1的间隔信息作为参考间隔信息，并设置各个载波上的间隔信息与参考间隔信息相同，因此载波2需要丢弃不属于目标时间内的S-SSB的传输(即图7中所示的S-SSB2)。
可以理解，另一种方式，对于任意载波，若该任意载波存在第二时间(即不传输S-SSB/S-SSB组的时间)，且与由参考间隔信息确定的S-SSB/S-SSB组配置对齐，则UE可以从第二时间的起点开始传输虚拟S-SSB/S-SSB组(即填充信息(例如冗余信息)或特定信息)。
示例性地，如图8所示，载波1和载波2进行CA，假设同步周期为160ms，载波1的SCS＝30kHz，载波2的SCS＝60kHz，载波1和载波2的同步周期内传输的S-SSB数量的原始配置分别为1和2。UE将载波1上的第一时间作为目标时间，将载波2的间隔信息作为参考间隔信息，并设置各个载波上的间隔信息与参考间隔信息相同，因此载波1需要从第二时间的起点开始发送一个虚拟S-SSB(即图8中所示的S-SSB2)。
需要说明的是，对于上述公共间隔信息和参考间隔信息的方案，公共间隔信息的方案是直接将公共间隔信息应用于所有载波，而参考间隔信息的方案是在各个载波原来的间隔信息的基础上，通过丢弃某些载波上的同步资源，或者在某些载波上发送虚拟同步资源，使得各个载波上的同步资源与由参考间隔信息确定的同步资源处于相同时间。
本申请实施例中，UE可以根据网络侧设备配置、预配置、其他用户设备指示或UE自主决定，确定参考间隔信息(即参考S-SSB/S-SSB组配置)，然后将各个载波上的S-SSB/S-SSB组配置与参考间隔信息对比，通过丢弃某些载波上的S-SSB，或者在某些载波上发送虚拟S-SSB，使得各个载波上的同步资源与由参考间隔信息确定的同步资源处于相同时间，从而保证各载波上的同步资源对齐。
可选地，本申请实施例中，上述目标间隔信息由载波的SCS确定，包括以下一项：由第一载波上同步资源的配置参数确定、不同载波上同步资源的数量为预设值。
需要说明的是，上述不同载波可以为不同SCS的载波，或者不同其他属性的载波，具体的可以根据使用需求确定，本申请实施例在此不作限制。
可以理解，一种方式，UE可以根据网络侧设备配置、预配置、其他用户设备指示或UE自主决定，确定第一载波，并根据第一载波上同步资源的配置确定其他载波上同步资源的配置，使得各个载波上同步资源所占的时间长度相同。
可选地，本申请实施例中，载波i上S-SSB的数量ssbnum i为：
Figure PCTCN2022088217-appb-000003
其中，u 1为第一载波对应的子载波间隔因子，u i为载波i对应的子载波间隔因子，ssbnum 1为第一载波上SSB的数量。
可以理解，另一种方式，UE可以将不同SCS的载波上同步资源的数量分别设置为固定值，使得各个载波上同步资源所占的时间长度相同。例如，配置SCS＝15kHz的载波上S-SSB的数量为1，SCS＝30kHz的载波上S-SSB的数量为2，SCS＝60kHz的载波上S-SSB的数量为4。或者，配置SCS＝15kHz的载波上S-SSB的数量为2，SCS＝30kHz的载波上S-SSB的数量为4，SCS＝60kHz的载波上S-SSB的数量为8。
示例性地，如图9所示，载波1，2和3进行CA，假设同步周期为160ms，载波1的SCS＝15kHz，载波2的SCS＝30kHz，载波3的SCS＝60kHz，配置载波1，2和3的同步周期内传输的S-SSB数量分别为1，2和4，此时任意载波上的第一时间均可以作为第二时间，各载波的同步资源保持对齐。
本申请实施例中，由于各个载波的SCS可能不同，因此可以根据载波的SCS，对对应载波的同步资源进行配置，使得各个载波上的同步资源对齐。

可以理解，对于定时同步：UE可以将第一载波对应的同步参考源(synchronization reference source)作为其他载波的同步参考(synchronization reference)。需要说明的是，上述定时同步可以理解为：基于第一载波对应的定时确定其他载波的定时。
对于传输方向同步：UE可以根据网络侧设备配置、预配置、其他用户设备指示或UE自主决定，确定第一载波上同步资源的传输方向，并设置其他载波上与第一载波同步资源对齐的同步资源的传输方向与第一载波相同。
可选地，本申请实施例中，上述定时同步包括以下至少一项：帧边界对齐、子帧边界对齐、时隙边界对齐、符号边界对齐、秒/毫秒/微秒级对齐。

可以理解，UE至少在第一载波上传输同步信号。一种方式中，当仅允许在一个载波上传输同步资源上的同步信号时，UE可以在第一载波上传输同步信号；另一种方式中，当允许在多个载波上传输同步资源上的同步信号时，UE可以根据至少两个载波上的间隔信息的值，决定是否在各自载波上传输同步信号。
示例性地，若载波1上的间隔信息的值为1，则UE在载波1上传输同步信号，若载波1上的间隔信息的值为0，则UE不在载波1上传输同步信号。
需要说明的是，当传输超出UE能力时(例如超出传输载波数上限)，UE自主决定传输同步信号的载波，例如UE在满足传输条件的载波中进行随机选择。
本申请实施例中，UE可以在确定目标配置参数之后，可以仅在第一载波上传输同步信号，或者根据UE的能力确定传输同步信号的载波，或者根据目标配置参数，在至少两个载波上的同步资源上传输同步信号。
