或者，终端设备根据第一侧行配置授权中的目标侧行传输资源与第一个侧行传输资源在时域上的偏移值，确定第一侧行配置授权的时域资源，也即，在第一侧行配置授权的一个周期内包括多个侧行传输资源的情况下，可以基于偏移值确定其他侧行传输资源。

需要说明的是，在侧行通信中，根据进行通信的终端所处的网络覆盖情况，可以分为网络覆盖内侧行通信，如图1所示；部分网络覆盖侧行通信，如图2所示；及网络覆盖外侧行通信，如图3所示。
图1：在网络覆盖内侧行通信中，所有进行侧行通信的终端均处于同一基站的覆盖范围内，从而，上述终端均可以通过接收基站的配置信令，基于相同的侧行配置进行侧行通信。
图2：在部分网络覆盖侧行通信情况下，部分进行侧行通信的终端位于基站的覆盖范围内，这部分终端能够接收到基站的配置信令，而且根据基站的配置进行侧行通信。而位于网络覆盖范围外的终端，无法接收基站的配置信令，在这种情况下，网络覆盖范围外的终端将根据预配置(pre-configuration)信息及位于网络覆盖范围内的终端发送的物理侧行广播信道(Physical Sidelink Broadcast Channel，PSBCH)中携带的信息确定侧行配置，进行侧行通信。
图3：对于网络覆盖外侧行通信，所有进行侧行通信的终端均位于网络覆盖范围外，所有终端均根据预配置(pre-configuration)信息确定侧行配置进行侧行通信。
需要说明的是，设备到设备通信是基于终端到终端(Device to Device，D2D)的一种侧行链路(Sidelink，SL)传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，因此具有更高的频谱效率以及更低的传输时延。车联网系统采用终端到终端直接通信的方式，在3GPP定义了两种传输模式，分别记为：模式A和模式B。本申请实施例可以应用于模式A和/或模式B。
模式A：终端的传输资源是由基站分配的，终端根据基站分配的资源在侧行链路上进行数据的发送；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。如图1所示，终端位于网络覆盖范围内，网络为终端分配侧行传输使用的传输资源。
模式B：终端在资源池中选取一个资源进行数据的传输。如图3所示，终端位于小区覆盖范围外，终端在预配置的资源池中自主选取传输资源进行侧行传输；或者，如图1所示，终端在网络配置的资源池中自主选取传输资源进行侧行传输。
需要说明的是，在NR-V2X中，用户可能处在一个混合的模式下，即既可以使用模式A进行资源的获取，又同时可以使用模式B进行资源的获取。
在NR-V2X中，支持自动驾驶，因此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，其接收端终端只有一个终端，如图4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5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终端；对于广播传输方式，其接收端是发送端终端周围的任意一个终端，如图6所示，UE1是发送端终端，其周围的其他终端，UE2-UE6都是接收端终端。
在侧行传输系统中引入了资源池，所谓资源池即传输资源的集合，无论是网络配置的传输资源还是终端自主选取的传输资源，都是资源池中的资源。可以通过预配置或网络配置的方式配置资源池，可以配置一个或多个资源池。资源池又分为发送资源池和接收资源池。发送资源池即该资源池中的传输资源用于发送侧行数据；接收资源池即终端在该资源池中的传输资源上接收侧行数据。
在LTE-V2X中，物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)资源池中用于模式3(即上述模式A)或模式4(即上述模式B)侧行传输的子帧集合可以表示为
Figure PCTCN2020104893-appb-000001
其中，
Figure PCTCN2020104893-appb-000002
子帧索引相对于服务小区的SFN0或DFN0的无线帧的子帧#0。
该子帧集合包括除以下子帧外的所有子帧：
●配置有侧行同步信号(Sidelink Synchronization Signal，SLSS)资源的子帧；
●TDD系统中的下行子帧和特殊子帧；
●预留子帧。
终端设备确定分配给PSSCH资源池的子帧的集合如下：
终端设备根据比特位图
Figure PCTCN2020104893-appb-000003
确定PSSCH资源池的时域资源；
如果b k'＝1，子帧
Figure PCTCN2020104893-appb-000004
属于资源池。其中，k'＝k mod L bitmap，比特位图的长度L bitmap由高层配置。
在LTE-V2X中，在一个系统帧号(System Frame Number，SFN)或直接帧号(Direct Frame Number，DFN)周期内确定资源池，一个SFN周期包括10240个子帧，分别对应子帧0,1,2,…,10239(又称为物理时隙或物理子帧)；去掉同步子帧、下行子帧、特殊子帧(即TDD系统中的下行子帧和特殊子帧)、以及预留子帧(reserved subframe)，剩余的子帧编号为
Figure PCTCN2020104893-appb-000005
剩余的子帧的个数能够被L bitmap整除，比特位图
Figure PCTCN2020104893-appb-000006
在剩余的子帧中周期重复，比特为1表示该比特在该剩余子帧中对应的子帧属于该资源池，否则不属于该资源池。
如图7所示，一个SFN周期(或DFN周期)包括10240个子帧，同步信号的周期是160ms，在一个同步周期内包括2个同步子帧，因此，在一个SFN周期内共有128个同步子帧，用于指示资源池时域资源的比特位图的长度是10比特，因此需要2个预留子帧(reserved subframe)，剩余子帧个数是(10240-128-2＝10110)，可以被比特位图的长度10整除，将剩余的子帧重新编号为0,1,2,…,10109(又称为逻辑时隙或逻辑子帧)，比特位图前3位为1，其余7位为0，即，在剩余子帧中，每10个子帧中的前3个子帧属于该资源池，其余的子帧不属于该资源池。由于在剩余子帧中需要比特位图重复1011次，以指示所有的子帧是否属于资源池，而在每个比特位图周期内包括3个子帧，因此在一个SFN周期共有3033个子帧属于该资源池。
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，即上述模式B；在模式1中，网络为终端分配侧行传输资源，即上述模式A。具体地，网络设备可以通过动态调度(Dynamic Scheduling，DG)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，或称为侧行免授权传输资源。SL CG主要包括两种配置授权方式：第一类侧行配置授权(type-1 Sidelink configured grant，type-1 SL CG)和第二类配置授权(type-2 Sidelink configured grant，type-2 SL CG)。
第一类侧行配置授权：网络设备通过无线资源控制(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、解调参考信号(Demodulation Reference Signal，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。当终端设备接收到该高层参数后，可立即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。
第二类侧行配置授权：采用两步的资源配置方式，即RRC+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、MCS等在内的其他传输资源和传输参数。终端设备在接收到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激活该侧行配置授 权的下行控制信息(Downlink Control Information，DCI)后，才能进行侧行传输。此外，网络可以通过DCI去激活该侧行配置授权，当终端接收到去激活的DCI后，不能再使用该侧行配置授权传输资源进行侧行传输。
对于第一类侧行配置授权(type-1 SL CG)，通过如下公式1确定其对应的时域资源：
[(SFN×numberOfSLSlotsPerFrame)+logical slot number in the frame]＝(timeReferenceSFN×numberOfSLSlotsPerFrame+sl-TimeOffsetCGType1+S×PeriodicitySL)modulo(1024×numberOfSLSlotsPerFrame)        公式1
其中，在公式1中，
Figure PCTCN2020104893-appb-000007
N表示20ms的时间范围中可以用于侧行传输的逻辑时隙的数量，sl_periodCG表示网络配置的SL CG的周期；numberOfSLSlotsPerFrame表示一个无线帧中可以用于侧行传输的逻辑时隙的数量；logical slot number in the frame表示无线帧中逻辑时隙的数量；timeReferenceSFN表示时间参考SFN；sl-TimeOffsetCGType1表示type-1CG的时域偏移；S表示任意整数。
对于第二类侧行配置授权(type-2 SL CG)，通过如下公式2确定其对应的时域资源：
[(SFN×numberOfSLSlotsPerFrame)+logical slot number in the frame]＝[(SFN start time×numberOfSLSlotsPerFrame+slot start time)+S×PeriodicitySL]modulo(1024×numberOfSLSlotsPerFrame)     公式2
其中，在公式2中，
Figure PCTCN2020104893-appb-000008
N表示20ms的时间范围中可以用于侧行传输的逻辑时隙的数量，sl_periodCG表示网络配置的SL CG的周期；numberOfSLSlotsPerFrame表示一个无线帧中可以用于侧行传输的逻辑时隙的数量；logical slot number in the frame表示无线帧中逻辑时隙的数量；SFN start time表示CG资源中的第一个PSSCH传输机会所对应的SFN；slot start time表示CG资源中的第一个PSSCH传输机会所对应的逻辑时隙；sl-TimeOffsetCGType1表示type-1CG的时域偏移；S表示任意整数。
然而，在上述公式1和公式2中存在如下3个问题：
问题1，在公式1和公式2中，
Figure PCTCN2020104893-appb-000009
该公式得到的参数PeriodicitySL，包括所有可用于侧行传输的逻辑时隙(例如，对应图7中的第二行)，而SL CG是配置在某个资源池中的(例如，对应图7中的第三行)，而用于指示资源池时隙的比特位图(bitmap)的长度是[10,100]中的任意一个值，与20ms时间范围内包括的时隙个数可能不存在整数倍的关系，因此，按照上述公式1和公式2确定的时隙可能是不属于该SL CG所关联的资源池，因此也就不属于侧行配置授权的时域传输资源。
问题2：在上述公式1和公式2中，numberOfSLSlotsPerFrame表示一个无线帧中可以用于侧行传输的逻辑时隙的数量，但是在确定周期的公式中是以20ms为周期确定的，20ms包括2个无线帧，在每个无线帧内可用于侧行传输的逻辑时隙的个数可能是不同的，例如，20ms内包括10个可用于侧行传输的逻辑时隙，但是在前10ms(一个无线帧)内包括3个逻辑时隙，在后20ms(另一个无线帧)内包括7个逻辑时隙，此时，numberOfSLSlotsPerFrame的取值在不同的无线帧中是不同的，该如何取值，无法确定是3还是7。
问题3：对于SL CG，在每个CG周期内，网络设备可以配置最多3个传输资源，而在上述确定侧行配置授权传输资源的公式中，只考虑了每个周期内的第一个传输资源，即type-1 SL CG中的sl-TimeOffsetCGType1，以及type-2 SL CG中的SFN start time和slot start time，并没有考虑第2个或第3个传输资源所对应的时域位置。
基于上述问题，本申请提出了一种确定侧行链路配置授权资源的方案，可以解决上述技术问题。
以下通过具体实施例详述本申请的技术方案。
图8是根据本申请实施例的确定侧行链路配置授权资源的方法200的示意性流程图，如图8所示，该方法200可以包括如下内容中的至少部分内容：
S210，终端设备根据第一信息确定第一侧行配置授权的时域资源，其中，
该第一信息包括但不限于以下中的至少一种：
该第一侧行配置授权的周期在该第一侧行配置授权关联的资源池内对应的时隙数量，一个无线帧中用于侧行传输的逻辑时隙的平均数量，双SFN的时间范围内的SFN信息，双SFN的时间范围内的逻辑时隙信息，双SFN的时间范围内的时域偏移，该第一侧行配置授权中的目标侧行传输资源与第 一个侧行传输资源在时域上的偏移值。
需要说明的是，在本申请实施例中，双SFN的时间范围可以是20ms的时间范围。
可选地，该第一侧行配置授权可以是第一类侧行配置授权，其中，该第一类侧行配置授权为网络设备通过RRC信令配置的侧行配置授权。具体可以参照上述关于第一类侧行配置授权的相关描述，为了简洁，在此不再赘述。
可选地，该第一侧行配置授权也可以是第二类侧行配置授权，其中，该第二类侧行配置授权为网络设备通过RRC信令配置且通过DCI激活的侧行配置授权。具体可以参照上述关于第二类侧行配置授权的相关描述，为了简洁，在此不再赘述。
可选地，作为示例1，该第一信息包括该第一侧行配置授权的周期在该第一侧行配置授权关联的资源池内对应的时隙数量。也即，该终端设备可以根据该第一侧行配置授权的周期在该第一侧行配置授权关联的资源池内对应的时隙数量确定该第一侧行配置授权的时域资源。
可选地，在示例1中，该第一侧行配置授权的周期在该第一侧行配置授权关联的资源池内对应的时隙数量由以下信息中的至少一种确定：
用于配置资源池时域资源的比特位图的总长度，用于配置资源池时域资源的比特位图中取第一值的数量，网络设备配置的该第一侧行配置授权的周期。
可选地，该第一侧行配置授权关联的资源池在该比特位图中的取值为该第一值。
例如，该第一值为1。
可选地，在示例1中，该第一侧行配置授权的周期在该第一侧行配置授权关联的资源池内对应的时隙数量可以通过如下公式3得到。
Figure PCTCN2020104893-appb-000010
其中，N表示20ms的时间范围中可以用于侧行传输的逻辑时隙的数量，sl_periodCG表示网络配置的第一侧行配置授权的周期，k表示用于配置资源池时域资源的比特位图中取值为1的数量，L表示用于配置资源池时域资源的比特位图的总长度。
具体地，在示例1中，终端设备可以基于公式3得到PeriodicitySL。
进一步地，在该第一侧行配置授权为第一类侧行配置授权(type-1 SL CG)的情况下，该终端设备将公式3得到的PeriodicitySL代入上述公式1，以确定该第一侧行配置授权的时域资源。或者，在该第一侧行配置授权为第二类侧行配置授权(type-2 SL CG)的情况下，该终端设备将公式3得到的PeriodicitySL代入上述公式2，以确定该第一侧行配置授权的时域资源。
在示例1中，如果时隙A属于该第一侧行配置授权的一个传输机会，那么，时隙A+PeriodicitySL也是属于该第一侧行配置授权对应的资源池，并且也是一个该第一侧行配置授权的传输机会。
在示例1中，例如，网络设备配置20ms内可用于侧行传输的资源如下图9和图10所示，即在第一个10ms内包括3个可用于侧行传输的时隙，在第二个10ms内包括7个可用于侧行传输的时隙，此时，N＝10。用于配置资源池时域资源的比特位图的长度是15比特，每3比特设置一个1，即每15个可用于侧行传输的时隙中的包括5个属于该资源池的时隙，第一侧行配置授权与该资源池相关联。
例如，假设第一侧行配置授权为第一类侧行配置授权(type-1 SL CG)，且该第一侧行配置授权的周期为20ms，按照
Figure PCTCN2020104893-appb-000011
计算得到PeriodicitySL＝10，如果网络设备配置的sl-TimeOffsetCGType1＝0，按照上述公式1，逻辑时隙0,10,20,30,…是该第一侧行配置授权所对应的的时隙，但是根据资源池配置信息可知，时隙10和时隙20并不属于该第一侧行配置授权关联的资源池，如下图9中第四行所示，这两个时隙(时隙10和时隙20)并不属于该第一侧行配置授权对应的时域传输资源，也就不是该第一侧行配置授权可用的传输资源。因此，根据公式
Figure PCTCN2020104893-appb-000012
确定的该第一侧行配置授权的时域资源为时隙0、30，该第一侧行配置授权的相邻两个时域资源的间隔为30个时隙，即30ms，远远大于网络设备配置的该第一侧行配置授权的周期10ms。
又例如，假设第一侧行配置授权为第一类侧行配置授权(type-1 SL CG)，且该第一侧行配置授权的周期为20ms，L＝15，k＝5，N＝10，按照
Figure PCTCN2020104893-appb-000013
计算得到PeriodicitySL＝4，即该第一侧行配置授权的周期为4个时隙，该4个时隙是该第一侧行配置授权相 关联的资源池中的4个时隙，如果网络设备配置的sl-TimeOffsetCGType1＝0，按照上述公式1，资源池中的逻辑时隙0,4,8,12,…是该第一侧行配置授权所对应的的时隙，分别对应可用于侧行传输时隙集合中的逻辑时隙0、12、24、36，即该第一侧行配置授权的相邻两个时域资源的间隔为12个时隙，如图10所示，更接近于网络设备配置的真实周期值(10ms)。
因此，在示例1中，通过上述公式3将网络设备配置的第一侧行配置授权的周期转换为第一侧行配置授权的周期在第一侧行配置授权关联的资源池内对应的时隙数量，使得在第一侧行配置授权的传输资源确定公式中在其相关联的资源池中确定属于第一侧行配置授权的时隙，避免出现某个时隙不属于第一侧行配置授权关联的资源池的情况。
可选地，作为示例2，该第一信息包括一个无线帧中用于侧行传输的逻辑时隙的平均数量。也即，该终端设备可以根据该一个无线帧中用于侧行传输的逻辑时隙的平均数量确定该第一侧行配置授权的时域资源。
可选地，在示例2中，该一个无线帧中用于侧行传输的逻辑时隙的平均数量包括：
双SFN的时间范围内的第一个无线帧内用于侧行传输的逻辑时隙的数量和双SFN的时间范围内的第二个无线帧内用于侧行传输的逻辑时隙的数量的平均值。
在示例2中，该一个无线帧中用于侧行传输的逻辑时隙的平均数量可以通过如下公式4得到：averagenumberOfSLSlotsPerFrame＝(numberOfSLSlotsFirstFrame+numberOfSLSlotsSecondFrame)/2  公式4
其中，averagenumberOfSLSlotsPerFrame表示一个无线帧中用于侧行传输的逻辑时隙的平均数量，numberOfSLSlotsFirstFrame表示双SFN的时间范围内的第一个无线帧内用于侧行传输的逻辑时隙的数量，numberOfSLSlotsSecondFrame表示双SFN的时间范围内的第二个无线帧内用于侧行传输的逻辑时隙的数量。
需要说明的是，在示例2中，将上述公式1和公式2中的numberOfSLSlotsPerFrame替换为averagenumberOfSLSlotsPerFrame，即可确定该第一侧行配置授权的时域资源。
因此，在示例2中，以一个无线帧中用于侧行传输的逻辑时隙的平均数量确定第一侧行配置授权的时域资源，避免了numberOfSLSlotsPerFrame在每个无线帧内数量不同的问题。
可选地，作为示例3，该第一信息包括：双SFN的时间范围内的SFN信息，双SFN的时间范围内的逻辑时隙信息和双SFN的时间范围内的时域偏移。也即，在示例3中，该终端设备可以根据该双SFN的时间范围内的SFN信息，该双SFN的时间范围内的逻辑时隙信息和该双SFN的时间范围内的时域偏移，确定该第一侧行配置授权的时域资源。
可选地，在示例3中，该双SFN的时间范围内的SFN信息包括以下中的至少一种：
双SFN的时间范围内的SFN索引、双SFN的时间范围内用于确定时域偏移的参考SFN索引、该第一侧行配置授权中第一个传输机会对应的双SFN的索引。
可选地，在示例3中，该双SFN的时间范围内的逻辑时隙信息包括以下中的至少一种：
双SFN的时间范围内用于侧行传输的逻辑时隙的数量，双SFN的时间范围内用于侧行传输的逻辑时隙的索引，该第一侧行配置授权中第一个传输机会对应的双SFN的时间范围内的逻辑时隙的索引。
可选地，在示例3中，该双SFN的时间范围内的时域偏移包括以下中的一种：
相对于SFN＝0的时域偏移，相对于双SFN的时间范围内用于确定时域偏移的参考SFN索引的时域偏移。
