车联网***是基于D2D的一种侧行链路(Sidelink，SL)传输技术，与传统的LTE***中通信数据通过基站接收或者发送的方式不同，车联网***采用终端到终端直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。
在3GPP的版本14(Rel-14)中对V2X进行了标准化，定义了两种传输模式：模式3和模式4。其中，图2示出了根据本申请实施例的车联网***中两种传输模式的示意图。
如图2所示，左侧的模式3表示：车载终端的传输资源是由基站通过下行链路(downlink，DL)分配的，车载终端根据基站分配的资源在SL上进行数据的发送；基站可以为车载终端分配单次传输的资源，也可以为车载终端分配半静态传输的资源。
如图2所示，右侧的模式4表示：车载终端采用侦听(sensing)和预留(reservation)的传输方式传输SL。车载终端在资源池中通过侦听的方式获取可用的传输资源集合，车载终端从该集合中随机选取一个资源进行数据的传输。由于车联网***中的业务具有周期性特征，因此车载终端通常采用半静态传输的方式，即车载终端选取一个传输资源后，就会在多个传输周期中持续的使用该资源，从而降低资源重选以及资源冲突的概率。车载终端会在本次传输的控制信息中携带预留下次传输资源的信息，从而使得其他车载终端可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用，达到降低资源冲突的目的。
其中，对于终端自主选取传输资源的方式(例如上述LTE-V2X中模式4)，终端通过侦听从候选资源集合中选取传输资源。下面将结合图3对侦听和资源选取的过程进行简单描述。
图3示出了侦听和资源选择的示意图，对于每个侧行链路进程(sidelink process)，如图3所示，假设在时刻n有新的数据包到达，需要进行资源选取用于数据传输。终端可以先确定资源选择窗的范围为[n+T1,n+T2]，并且，终端在侦听窗[n-1000,n-1]内进行侦听，从而根据侦听窗内的侦听结果在选择窗内进行资源选取。这里假设T1≤4；20≤T2≤100。
终端在选择窗内进行资源选取的过程可以参照3GPP TS36.213中的操作步骤，此处仅以几个主要的资源选取步骤为例进行说明。假设终端将选择窗内所有可用的资源作为一个集合A，终端对集合A中的资源可以进行如下几个排除操作。
1、如果终端在侦听窗内某些子帧中没有侦听结果，例如若终端在某一子帧上发送数据，则该终端在该子帧上没有侦听结果，例如图3中侦听窗内的白色虚线块可以为没有侦听结果的子帧，那么这些子帧在K个周期后(例如图3中是一个周期以后)，在选择窗内对应的子帧上的资源需要被排除掉，即排除图3中的选择窗内的黑色方块。
2、如果终端侦听窗内检测到物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)，例如，图3中侦听窗内的黑色方块，并且其调度的PSSCH(即图3中选择窗内的白色虚线方块)的PSSCH-参考信号接收功率(Reference Signal Receiving Power，RSRP)高于门限，并且该控制信息PSCCH预留的下一个传输资源与该终端待发送的数据存在资源冲突，则在集合A中排除掉该资源，即排除图3中选择窗内的白色虚线方块。
3、如果集合A中剩余的资源个数小于选择窗内总资源个数20％，终端会提升PSSCH-RSRP的门限，例如，可以提高3dB，并且重复上述步骤1和2，直到集合A中剩余的资源个数大于或者等于选择窗内总资源数的20％。
4、终端对集合A中剩余的资源进行侧行链路接收的信号强度指示(Sidelink Received Signal Strength Indication，S-RSSI)检测，并且按照能量高低进行排序，把选择窗内没有被排除的资源中能量最低的20％资源(总资源的20％)放入集合B中。
5、终端从集合B中选取一个资源进行数据传输，例如，终端可以等概率的随机选择。
上述侦听和资源选取都是在PSCCH或者PSSCH的资源池中进行的，在LTE-V2X中，PSSCH的传输资源和PSCCH的传输资源是一一对应的，因此确定了PSSCH的传输资源也就确定了其对应的PSCCH的传输资源。
在LTE-V2X中，SLSS和PSBCH占据一个子帧，但是用于传输SLSS/PSBCH的子帧并不包括在PSSCH的资源池中。如图4所示，每一个小长方形方块在时域上表示一个子帧，其中，SLSS/PSBCH占据6物理资源模块(Physical Resource Block，PRB)以及一个子帧，该子帧不包括在PSCCH/PSSCH的资源池中。另外，在SLSS/PSBCH子帧中，SLSS/PSBCH占据带宽中间频域资源，两侧的资源空闲不用于传输侧行数据。
在NR-V2X中，需要支持自动驾驶，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NR-V2X***中，引入了多种传输模式，例如，模式1和模式2，其中，模式1是网络为终端分配传输资源(类似于LTE-V2X中的mode 3)，模式2是终端选取传输资源。在模式2中，支持终端通过侦听获取可用的传输资源。
NR-V2X中，同步信号和PSBCH一起构成一个侧行同步信号块(Sidelink Synchronization Signal Block，S-SSB)。具体地，图5示出了一个S-SSB的示意图，如图5所示，对于一个S-SSB，可以包括侧行主同步信号(Sidelink Primary Synchronization Signal，S-PSS)、侧行辅同步信号(Sidelink Secondary Synchronization Signal，S-SSS)以及PSBCH。在时域上，一个S-SSB占据相邻的4个OFDM符号，而频域占据20PRB。因此，一个S-SSB可能只占据一个子帧或时隙(slot)的一部分。
在NR-V2X***中，***的带宽可以支持到上百兆赫(MHz)，如果采用和LTE-V2X相同的方式，即在PSSCH的资源池中不包括传输SLSS的子帧(或时隙，或时域符号)，会造成资源浪费，因为SLSS的传输通常带宽比较窄。例如，如果NR-V2X的一个载波 包括100MHz带宽，其中20MHz用于传输SLSS，如果把SLSS的子帧排除在PSSCH资源池之外，则在SLSS子帧中的其余80MHz也不能用于传输PSSCH，会导致资源浪费。如果在PSSCH的资源池中包括SLSS所在的时域资源，此时如何进行侦听和资源选取是目前亟待解决的问题。
因此，本申请实施例提出了一种传输侧行信道的方法200，可以在资源池中选择用于传输侧行信道的资源，并且避免资源浪费。
图6为本申请实施例提供的一种传输侧行信道的方法200的示意性流程图。该方法200可以由终端设备执行，这里称该终端设备为第一终端设备，该第一终端设备可以指任意一个支持侧行数据传输的终端设备，例如，该终端设备可以为如图1所示的任意一个终端设备，也可以为如图2所示的任意一个终端设备。如图6所示，该方法200包括：S210，第一终端设备排除第一资源集合中的至少一个候选资源后，获得第二资源集合，该第一资源集合中包括多个候选资源，该多个候选资源中每个候选资源能够用于发送第一侧行信道；S220，该第一终端设备在该第二资源集合中，确定目标资源；S230，该第一终端设备采用该目标资源，发送该第一侧行信道。
本申请实施例中发送侧行信道可以指发送该侧行信道承载的数据，同样的，本申请实施例中的接收侧行信道可以指接收该侧行信道承载的数据。例如，以第一种终端设备发送第一侧行信道为例，其可以指第一终端设备向其他终端设备发送该第一侧行信道承载的数据。
应理解，在S210之前，该方法200还包括：该第一终端设备确定第一资源集合，具体地，图7示出了根据本申请实施例的侦听窗和选择窗的示意图，如图7所示，这里假设第一终端设备在时刻n有新的数据包到达，需要进行资源选取用于侧行信道传输。则该第一终端设备可以确定第一资源集合的时域范围为时隙(或子帧)[n+T1,n+T2]，也就是图7中的资源选择窗的范围[n+T1,n+T2]，其中T1和T2均为大于0的整数。
具体地，该T1和/或T2的值可以为终端设备自主选取的，即该方法200还可以包括：该第一终端设备根据该第一侧行信道承载的数据的业务属性，确定该第一资源集合的大小。其中，该第一侧行信道承载的数据的业务属性可以包括以下属性中的至少一种：优先级、可靠性、时延、传输速率、QoS类标识符(QoS class identifier，QCI)、QoS流标识符(QoS Flow Identifier，QFI)以及PC5接口QoS索引(PC5 QoS Index，PQI)。例如，该第一终端设备可以根据侧行信道承载的数据的业务的属性或者需求选取T2，例如根据业务的时延需求选取T2，T2小于或等于业务的时延需求，例如，图7中取T2为100个时隙。
该方法200还包括：终端设备在该第一资源集合中确定多个候选资源，其中，该多个候选资源中每个候选资源均能够用于发送第一侧行信道，该第一侧行信道为该第一终端设备与其他终端设备之间传输的任意侧行信道。具体地，对于如图7所示的第一资源集合，即图7中的选择窗，该第一终端设备可以将资源选择窗内的所有的传输资源作为可用的候选资源。该第一终端设备可以根据第一侧行信道占用资源的大小，可以在该第一资源集合中划分出多个候选资源，其中，每个候选资源均可以用于传输该第一侧行信道。例如，待传输的侧行信道对应的侧行数据需要占据1个时隙以及10个PRB，则每个候选资源都是占据1个时隙以及10个PRB的传输资源块。
在S210中，第一终端设备排除第一资源集合中的至少一个候选资源后，获得第二资源集合，即该第二资源集合为该第一资源集合的一个子集。具体地，该第一终端设备可以采用一种或者多种方式，在该第一资源集合中排除至少一个候选资源，其中，该至少一个候选资源中可以包括与其他资源重叠的资源。
例如，该至少一个候选资源中可以包括与S-SSB占用的资源重叠的资源，例如，如图7所示的选择窗内黑色方块表示S-SSB占用的资源，则该至少一个候选资源中可以包括与该黑色方块部分重叠的候选资源；另外，该至少一个候选资源中还可以包括与其他 终端设备的PSSCH或PSCCH占用资源重叠的资源，例如，如图7所示，除第一终端设备以外的UE1以及UE2在选择窗内分别对应有预留资源，即图7中选择窗内的白色虚线方块部分，则该至少一个候选资源中可以包括与该白色虚线方块部分重叠的候选资源。
下面将结合几个具体实施例，详细描述本申请实施例的在该第一资源集合中排除的至少一个候选资源的例子。
可选的，作为第一个实施例，该至少一个候选资源中可以包括第一候选资源，该第一候选资源与S-SSB占用的资源重叠，其中，与S-SSB占用的资源重叠的资源可以有一个或者多个，而该第一候选资源可以指与S-SSB占用的资源重叠的任意一个或者多个资源。具体地，如果在第一资源集合中，也就是如图7所示的资源选择窗内，存在任意一个或者多个候选传输资源和S-SSB的传输资源有重叠，则从该资源集合中排除掉该候选传输资源，即在该第一资源集合中排除第一候选资源。
本申请实施例中的S-SSB可以包括S-PSS、S-SSS以及PSBCH。例如，该S-SSB可以为如图5所示的S-SSB，为了简洁，在此不再赘述。
应理解，本申请实施例中的第一候选资源与S-SSB占用的资源重叠，可以指完全重叠，也可以指部分重叠，并且该重叠可以包括时域重叠和/或频域重叠。具体地，这里以第一候选资源与S-SSB占用的资源重叠为例进行说明。图8示出了本申请实施例的资源重叠的示意图，其中，图8中的(a)和(b)两个图中的实线框表示第一资源集合。
如图8中的左边(a)图所示，这里假设斜线方块表示S-SSB占用的资源，而该第一资源集合中的候选资源1与该S-SSB占用的资源在频域有部分重叠，在时域完全重叠，则该第一终端设备可以确定该候选资源1与S-SSB占用的资源重叠，则在第一资源集合中排除该候选资源1，即第一候选资源包括该候选资源1。
同样的，如图8中的右边(b)图所示，仍然假设斜线方块表示S-SSB占用的资源，而该第一资源集合中的候选资源2与该S-SSB占用的资源在频域有部分重叠，在时域也有部分重叠(例如，候选资源2占据一个时隙，S-SSB占据4个时域符号)，则该第一终端设备可以确定该候选资源2与S-SSB占用的资源重叠，则在第一资源集合中排除该候选资源2，即第一候选资源包括该候选资源2。
在该第一个实施例中，该S-SSB占用的资源位于第一资源集合中，导致与该第一资源集合中的候选资源存在重叠，进而排除重叠的第一候选资源。与之对应的，对于S-SSB为周期性传输的情况，还需要排除多个周期后可能出现的资源重叠的情况。
可选的，作为第二个实施例，对于该第一侧行信道以及S-SSB为周期性传输的情况，该至少一个候选资源还可以包括第二候选资源，该第二候选资源在N个传输周期中存在至少一次与S-SSB占用的资源重叠，其中，N为正整数。与第一候选资源类似，该第二候选资源也可以为一个或者多个资源，为了简洁，在此不再赘述。
具体地，如果S-SSB是周期性传输的，待传输的第一侧行信道承载的数据业务也是周期性传输的，则当终端在资源选择窗内选取传输资源时，会预留传输资源用于周期性业务传输。例如，对于第一资源集合中第二候选资源，即该第二候选资源可以为资源选择窗内的任意一个候选资源，假设采用该第二候选资源传输第一侧行信道承载的周期性的业务，终端设备会根据该业务的周期在随后的N个周期中持续使用对应该第二候选资源的资源传输周期性的业务，在这N个传输周期中，如果存在至少一次和S-SSB的传输资源有重叠，则终端设备就从第一资源集合中把该第二候选传输资源排除掉。
例如，图9示出了周期性传输的S-SSB和侧行信道的示意图。如图9所示，假设第一资源集合的范围为时隙[n+1,n+100]，即资源选择窗的范围为时隙[n+1,n+100]，对于其中的第二候选资源，假设在时刻n+k时刻的资源为第二候选资源，即选择窗内的白色虚线方块，如果该第一终端设备选取该第二候选资源进行侧行数据传输，并且该终端设备的待传输数据业务是周期性业务，业务周期为100ms，则该第一终端设备会在随后的N个周期中的n+k+m*100时刻使用该传输资源进行传输，其中m＝1,2,…,N。如果在这N个 周期内，存在至少一个资源和S-SSB的传输资源有重叠，如图中时刻n+k+100，则第一终端设备在第一资源集合中把该第二候选资源排除掉。
应理解，该数值N是正整数，该数值N可以为该第一终端设备确定的。例如，该数值N可以为预设值；或者，该数值N可以为第一终端设备在预设集合中确定的，其中，该预设集合为一个数值范围，该第一终端设备在该数值范围内选择一个数值作为数值N；或者，该数值N还可以为该第一终端设备根据网络发送的配置信息确定的，例如，该网络设备配置一个参数范围，第一终端设备从该参数范围内选取一个数值作为数值N；或者，该数值N可以为第一终端设备随机选取的。
因此，对于周期性业务的资源选取，在资源选择窗内将和当前或未来N个周期内的S-SSB存在资源冲突的资源排除掉，避免PSSCH的传输资源和S-SSB传输资源的冲突；适用于周期性业务的资源选取。
可选的，作为第三个实施例，该至少一个候选资源还包括第三候选资源，该第三候选资源与第一传输资源重叠，其中，该第一传输资源是第二终端设备预留用于传输第二侧行信道的资源，可选地，该第二侧行传输信道可以是PSCCH、PSSCH或物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)。具体地，如果第一终端在侦听窗内检测到第二终端设备在资源选择窗(即第一资源集合)内预留了第一传输资源，则该第一终端设备把和该第二终端设备的第一传输资源有重叠的候选资源从第一资源集合中排除掉，其中，该第二终端设备指除了第一终端设备以外的任意终端设备。
在本申请实施例中，该第一终端设备可以通过多种方式确定该第二终端设备的预留资源。例如，该第一终端设备可以通过在侦听窗内检测第二终端设备的侧行控制信息(Sidelink Control Information，SCI)，确定该第二终端设备的预留资源，也就是该第二终端设备的第一传输资源。
具体地，该方法200还可以包括：该第一终端设备接收该第二终端设备的SCI，该SCI承载在PSCCH信道中，该SCI包括第一指示信息，该第一指示信息用于指示该第二终端设备预留该第一传输资源。例如，如图10所示，第一终端设备确定的侦听窗的范围为[n-1,n-1000]。若第一终端设备在该侦听窗内检测到第二终端设备的SCI，该SCI中包括第一指示信息，该第一指示信息指示预留了选择窗(即第一资源集合)内的第一传输资源(即图10中选择窗内的白色虚线方块)用于传输第二终端设备的PSSCH，则第一终端设备可以排除第一资源集合中的第三候选资源，该第三候选资源为与该第二终端设备的第一传输资源重叠的资源。
或者，该第一终端设备还可以检测承载SCI的PSCCH的PSCCH-RSRP，并且将其与第一阈值进行比较，若PSCCH-RSRP大于或者等于第一阈值，则第一终端设备在第一资源集合内把和该第一传输资源有重叠的第三候选资源排除掉。
可选的，该SCI还可以包括第二指示信息，该第二指示信息指示传输第二终端设备的第三侧行信道的第二传输资源，其中，该第二传输资源在时域上不位于第一资源集合中，而位于该第一资源集合之前。
如图11所示，同样假设第一终端设备确定的侦听窗的范围为时隙[n-1,n-1000]。若第一终端设备在该侦听窗内检测到第二终端设备的SCI，该SCI包括第一指示信息和第二指示信息，其中，第二指示信息指示了第二传输资源传输第二终端设备的PSSCH，即图11中侦听窗内的白色方块；而第一指示信息指示预留了选择窗(即第一资源集合)内的第一传输资源(即图10中选择窗内的白色虚线方块)，其中，该第一传输资源可以用于传输第二终端设备的PSSCH的重传数据，或者，该第一传输资源可以用于传输周期性业务的下一个周期的PSSCH，则第一终端设备可以排除第一资源集合中的第三候选资源，该第三候选资源为与该第二终端设备预留的第一传输资源重叠的资源。
或者，第一终端设备还可以检测第二传输资源上的PSSCH的PSSCH-RSRP，并且将其与第二阈值比较，如果该PSSCH-RSRP大于或者等于第二阈值，则在第一资源集合内 把和第一传输资源有重叠的第三候选资源排除掉。另外，第一终端设备还可以检测承载SCI的PSCCH的PSCCH-RSRP，并且将其与第一阈值进行比较，若PSCCH-RSRP大于或者等于第一阈值，则第一终端设备在第一资源集合内把和该第一传输资源有重叠的第三候选资源排除掉。
应理解，上述第一阈值和/或第二阈值可以通过多种方式确定。例如，该第一阈值和/或该第二阈值可以为预配置的。又例如，该第一阈值和/或该第二阈值可以为网络设备配置的。再例如，该第一阈值和/或该第二阈值还可以为该第一终端设备根据相关参数确定的，本申请实施例并不限于此。
具体地，该第一阈值和/或该第二阈值可以为该第一终端设备根据以下方法中的至少一个确定的：该第一终端设备根据该第一侧行信道承载的数据的优先级和/或该侧行控制信息携带的优先级，确定该第一阈值和/或该第二阈值；该第一终端设备根据信道占用率(Channel Busy Ratio，CBR)，确定该第一阈值和/或该第二阈值。其中，上述优先级还可以替换为其他参数，例如：可靠性、时延、传输速率、服务质量(Quality of Service，QoS)参数、QCI、QFI以及PQI等，但本申请实施例并不限于此。
因此，在资源选择窗内将和其他终端预留的资源有重叠的资源排除掉，避免和其他终端的传输资源的冲突，可以适用于周期性业务或者非周期性业务的资源选取。
该第一终端设备通过上述三个实施例中全部或者部分实施例，在该第一资源集合中排除至少一个候选资源集合之后，获得第二资源集合；在S220中，该第一终端设备在该第二资源集合中，确定目标资源，以便于在S230中，该第一终端设备采用该目标资源，发送该第一侧行信道。具体地，该第一终端设备可以采用各种方法在该第二资源集合中确定目标资源。例如，该第一终端设备在该第二资源集合中，等概率随机确定该目标资源，但本申请实施例并不限于此。
因此，本申请实施例的传输侧行信道的方法，通过在包括多个候选资源的资源集合中，排除部分候选资源，可以避免资源重叠以及资源的浪费。例如，排除和S-SSB重叠的资源排除掉，避免PSSCH的传输资源和S-SSB传输资源的冲突；在资源选择窗内将和其他终端预留的资源有重叠的资源排除掉，避免和其他终端的传输资源的冲突；在资源选择窗内将和当前或未来N个周期内的S-SSB存在资源冲突的资源排除掉，避免PSSCH的传输资源和S-SSB传输资源的冲突，适用于周期性业务的资源选取。
本申请实施例还提出了另一种传输侧行信道的方式，终端设备在划分包括候选资源的资源池时，可以考虑划分为包括S-SSB占用的传输资源(即为S-SSB的传输资源)的资源池和不包括S-SSB的传输资源的资源池，以便于该终端设备可以在不包括S-SSB的传输资源的资源池中选择目标资源，并采用该目标资源传输侧行信道。
具体地，对于网络设备分配的候选资源池，该候选资源池中包括的候选资源可以用于终端设备选择用于传输侧行信道的目标资源，例如，图12示出了多个资源池的划分方法的示意图，如图12所示，该图12中的全部资源可以为网络设备配置的候选资源池中的候选资源。
终端设备可以根据该候选资源池中S-SSB的传输资源的位置，将该候选资源池划分为第一资源池和第二资源池，其中，第一资源池中不包括S-SSB占用的传输资源，而第二资源池中包括S-SSB占用的传输资源。这里以该第一资源池为第一PSSCH资源池，第二资源池为第二PSSCH资源池为例进行说明。
或者，该网络设备为该终端设备配置的候选资源池中包括该两个资源池，其中，第一PSSCH资源池不包括S-SSB资源，第二PSSCH资源池包括S-SSB资源。
具体地，该候选资源池中包括的第一PSSCH资源池和第二PSSCH资源池的划分方法可以如图12所示。
其中，在第一PSSCH资源池中不包括S-SSB的传输资源，因此在资源侦听和资源选取的过程中不需要考虑S-SSB传输资源的影响；而在第二PSSCH资源池中包括S-SSB 的传输资源，因此在资源选取的过程中需要考虑避免和S-SSB的传输资源冲突，具体的避免冲突的方式可以参照上述各个实施例，例如上述第一个实施例至第三个实施例中的一个或者多个，为了简洁，在此不再赘述。
可选地，除了采用上述各个实施例的排除方式以外，还可以直接把S-SSB所在的子帧(或者时隙)从第二PSSCH资源池中排除掉，即令第二PSSCH资源池不包括S-SSB所在的子帧或时隙，从而配置的PSSCH资源池和S-SSB的传输资源没有重叠，因此在资源侦听和选取的过程中不需要考虑S-SSB的传输资源。
因此，通过划分不同的PSSCH资源池，把S-SSB传输资源对资源选取的影响限定在特定的资源池中，对于没有S-SSB传输资源的资源池，则终端设备不需要考虑S-SSB传输资源的影响。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
另外，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。
上文中结合图1至图12，详细描述了根据本申请实施例的传输侧行信道的方法，下面将结合图13至图16，描述根据本申请实施例的终端设备。
