Description

通信方法及装置 技术领域
本申请涉及无线通信技术领域，尤其涉及一种通信方法及装置。
背景技术
目前的移动通信技术，例如侧行链路(sidelink，SL)通信场景，支持终端设备(terminal device)对周边其他终端设备进行感知。进行感知的终端设备能够接收附近的其他终端设备传输的侧行信息，以便根据接收的侧行信息获知附近的终端设备所采用的资源，例如监测周边终端设备发送的侧行控制信息，通过侧行控制信息获知该终端设备占用的资源，能够尽量避免在感知到有数据传输的资源上进行侧行链路(sidelink，SL)传输，以降低进行SL传输时受到的干扰。其中，感知的目的之一，是获知周边其他终端设备对于传输资源的占用情况，以便合理选择候选资源，并通过候选资源包含的传输资源进行SL数据传输。
目前，进行SL数据传输的终端设备确定传输资源的方式有待优化，以进一步提高终端设备选择的传输资源的合理性。
发明内容
本申请提供一种通信方法，以提高终端设备选择的SL传输资源的合理性。
第一方面，本申请实施例提供一种通信方法，该方法可以由终端设备或终端设备中的部件(比如处理器、通信芯片或芯片***等)执行。
下面以执行主体为终端设备为例进行描述。根据该方法，第一终端设备可接收来自于第二终端设备的，用于指示第一资源以及第一优先级的资源指示信息。其中，该第一资源为根据该第一优先级确定的。该第一终端设备根据第二优先级确定第二资源，其中，该第二优先级为该第一终端设备的待发送数据的优先级。该第一终端设备可在传输资源上发送该待发送数据，其中，该传输资源为根据该第一优先级、该第二优先级、该第一资源以及该第二资源确定的。
应理解，第二终端设备可以是接收该待发送数据的终端设备，或者接收该待发送数据的终端设备附近的一个终端设备。
采用以上方法，第一终端设备可根据第二终端设备感知的第一资源和第一资源对应的第一优先级，结合自身感知的第二资源和待发送数据的第二优先级确定传输资源，其中第一资源根据第一优先级确定，第二资源根据第二优先级确定。在本申请实施例提供的方法中第一终端设备在确定传输资源的时候同时考虑通过自身感知或监测获得的资源(第二资源)，以及其他终端设备通过资源指示信息所指示的资源(第一资源，也可以称为辅助资源)，通过其他终端设备的辅助扩大了第一终端设备监听资源的范围，使得第一终端设备选择的传输资源与周边终端设备产生干扰或碰撞的可能性更小，并且资源指示信息还包括第一资源对应的第一优先级，第一终端设备在选择传输资源时还考虑第一资源和第二资源分别对应的优先级(第一优先级和第二优先级)，能够进一步提高传输资源选择的合理性，降低通过该传输资源发送待发送数据时受到的干扰。
需要说明的是，本申请实施例中描述的第一资源对应的第一优先级以及第一资源根据 第一优先级确定，具体可以是表示第一资源是基于该第一优先级对应的参考信号接收功率(reference signal received power，RSRP)门限来进行感知(sensing)得到的。可选的，第一优先级可以是专门用于确定辅助资源的优先级，可以是基站配置或预定义的，终端设备(例如上述的第二终端设备)在作为辅助终端设备时，就根据该第一优先级对应的RSRP门限来选择资源。可选的，第一优先级也可以是第二终端设备当前的待发送数据或已经发送的数据的优先级。第一终端设备根据第二优先级确定第二资源，具体的也可以是第一终端设备基于第二优先级对应的RSRP门限进行感知得到第二资源，第一终端设备在通过感知确定用于自身待发送数据的候选资源(第二资源)时是基于待发送数据对应的优先级。第一终端设备和第二终端设备通过感知来选择资源的过程或方法可以是相同的。
在一种可能的设计中，在第一优先级的取值大于或等于第二优先级的取值的情况下，该传输资源属于第三资源和第二资源的交集。
或者，在第一优先级的取值大于或等于该第二优先级的取值，且该第三资源和第二资源的交集小于该待发送数据需要的资源的情况下，该传输资源可包括该交集以及第四资源，其中，该第四资源属于第三资源中除该交集以外的剩余资源。
或者，在该第一优先级的取值大于或等于该第二优先级的取值，且该第三资源小于该待发送数据需要的资源的情况下，该传输资源可包括该第三资源以及第五资源，其中，该第五资源属于第二资源中除该交集以外的剩余资源。
以上第三资源等于第一资源，或者，以上第三资源为根据该第一优先级和该第二优先级从该第一资源中确定的部分资源。
需要说明的是，本申请实施例中描述的资源A属于资源B表示资源A等于资源B，或者资源A为资源B中的部分资源。
采用该设计，因为在第一优先级取值大于或等于第二优先级的取值的情况下，第二资源中除上述交集以外的剩余资源存在较大可能会不符合待发送数据对资源的筛选需求，因此该设计可优先从第二资源和第三资源的交集中确定传输资源，次优将该交集和第三资源的剩余资源中的或全部资源作为传输资源，以降低根据第二资源中除该交集外的剩余资源确定传输资源的几率，提高根据选择传输资源的合理性。
在一种可能的设计中，在该第二优先级的取值大于或等于该第一优先级的取值的情况下，该传输资源属于第三资源和该第二资源的交集。
或者，在第二优先级的取值大于或等于该第一优先级的取值，且该第三资源和该第二资源的交集小于该待发送数据需要的资源的情况下，该传输资源包括该交集以及第六资源，其中，该第六资源属于该第二资源以及该第三资源的并集除该交集以外的剩余资源。
以上第三资源等于该第一资源，或者，以上第三资源为根据该第一优先级和该第二优先级从该第一资源中确定的部分资源。
采用该设计，在第二优先级的取值大于或等于第一优先级的取值的情况下，优先根据第二资源和第三资源的交集选择传输资源，提高根据选择传输资源的合理性。
在一种可能的设计中，该第一资源包括的资源单元的数量与该第三资源包括的资源单元的数量之间的差值，是根据该第一优先级的取值与该第二优先级的取值之间的差值确定的。
采用该设计可灵活确定第三资源。并且在第一优先级的取值大于第二优先级的取值时，根据第一优先级的取值与第二优先级取值之间的差值从第一资源中排除一部分资源单元， 第一优先级与第二优先级相差越远则排除的资源单元越多，以降低因为第一优先级较低导致的邻区干扰问题，提高确定传输资源时的合理性。
在一种可能的设计中，第一终端设备可接收来自至少一个第三终端设备的资源指示信息。其中，至少一个第三终端设备中的每个第三终端设备的资源指示信息所指示的优先级与第一优先级相同。则此时，传输资源为根据第一优先级、第二优先级、第一资源、第二优先级以及至少一个第三终端设备各自的资源指示信息分别指示的资源和优先级确定的。
采用该设计，在多个辅助终端设备分别的优先级相同时，第一终端设备可综合多个辅助终端设备的推荐资源确定传输资源，提高确定的传输资源的合理性。
在一种可能的设计中，在该第一优先级的取值大于或等于该第二优先级的取值的情况下，该传输资源属于第七资源和该第二资源的交集。
或者，在该第一优先级的取值大于或等于该第二优先级的取值，且该第七资源和该第二资源的交集小于该待发送数据需要的资源的情况下，该传输资源包括交集以及该第八资源，其中，该第八资源属于该第七资源中除该交集以外的剩余资源。
或者，在该第一优先级的取值大于或等于该第二优先级的取值，且该第七资源小于该待发送数据需要的资源的情况下，该传输资源包括该第七资源以及第九资源，该第就资源属于所述第二资源中除该交集以外的剩余资源。
以上第七资源为从该第一资源以及该至少一个第三终端设备各自的资源指示信息分别指示的资源中确定的。
采用该设计，因为在第一优先级取值大于或等于第二优先级的取值的情况下，该第七资源中除交集以外的剩余资源存在较大可能会不符合业务对资源的筛选需求，因此该设计可优先从第二资源和第七资源的交集中确定传输资源，次优将该交集和第七资源的剩余资源中的或全部资源作为传输资源，以降低根据第二资源中除该交集外的剩余资源确定传输资源的几率，提高根据选择传输资源的合理性。
在一种可能的设计中，在该第二优先级的取值大于或等于该第一优先级的取值的情况下，该传输资源属于第七资源和所述第二资源的交集。
或者，在该第二优先级的取值大于或等于该第一优先级的取值，且该第七资源小于该待发送数据需要的资源的情况下，该传输资源包括该交集以及第十资源，该第十资源属于该第二资源以及该第七资源的并集除该交集以外的剩余资源。
以上第七资源为从该第一资源以及该至少一个第三终端设备各自的资源指示信息分别指示的资源中确定的。
采用该设计，在第二优先级的取值大于或等于第一优先级的取值的情况下，优先根据第二资源和第七资源的交集选择传输资源，提高根据选择传输资源的合理性。
在一种可能的设计中，该第七资源为该第一资源包括的资源单元以及该至少一个第三终端设备各自的资源指示信息分别指示的资源包括的资源单元中，权值不低于第一阈值的至少一个资源单元。
可选的，第一阈值可以是预定义的，或由第一终端设备确定。
采用该设计，第一终端设备可根据每个资源单元的权值合理确定第七资源，进一步提高确定传输资源的合理性。
在一种可能的设计中，该第一优先级为该第一终端设备接收的来自一个或多个其他终端设备的资源指示信息所指示的优先级中与该第二优先级之间差值的绝对值最小的优先 级。
采用该设计，第一终端设备在接收多个优先级不同的辅助终端设备分别推荐的资源的情况下，可根据优先级与自身待发送数据的优先级最接近的辅助终端设备的推荐资源确定传输资源，而不需要根据其他辅助终端设备的辅助资源确定传输资源，以提高确定传输资源时的合理性。
第二方面，本申请实施例提供一种通信方法，该方法可以由终端设备或终端设备中的部件(比如处理器、通信芯片或芯片***等)执行。
下面以执行主体为终端设备为例进行描述。根据该方法，第二终端设备可根据第一优先级确定第一资源。第二终端设备向第一终端设备发送资源指示信息，该资源指示信息可指示该第一资源以及该第一优先级。

应理解，UE1以及UE2可被配置为支持SL通信，例如UE1与UE2之间可通过直接通信(PC5)空口进行SL通信。此外，UE1和/或UE2还能够与基站网络设备进行通信(例如，通过通用用户和网络的空口(universal user to network interface，Uu空口)进行通信)，并接受网络设备提供的网络服务。
图2中以基于移动蜂窝网的车联网通信技术(cellular based vehicle-to-everything，C-V2X/V2X)为例，示出了侧行传输通信场景的可能架构。
如图2所示，根据UE1与UE2具体形态的不同，V2X***又可分为车与车的通信(vehicle to vehicle，V2V)、车与行人的通信(vehicle to pedestrian，V2P)、车与基础设施的通信(vehicle to infrastructure，V2I)和车与网络的通信(vehicle to network，V2N)等类型。
其中，V2V***中，UE1与UE2分别作为车辆或车载设备进行SL通信。V2P***中，UE1与UE2中的一方作为车辆或车载设备，另一方作为行人手持或通过其他方式携带的通信设备进行SL通信。V2I***中，UE1与UE2中的一方作为车辆或车载设备，另一方作为路侧单元(road side unit，RSU)、智能路灯等基础设施进行SL通信。V2N***中，UE1与UE2中的一方作为车辆或车载设备，另一方作为基站等网络设备进行SL通信。
在NR V2X***中，资源分配(resource allocation，RA)是重要的技术分支。对于5G 基站(next generation node B，gNB)与UE之间的Uu接口，资源分配涉及到gNB为UE调度其在无线通信中应使用的时频资源，UE根据调度分配的时频资源可以接收来自gNB的下行链路(downlink，DL)信息，也可以向gNB发送上行链路(uplink，UL)信息。在NR***中，除Uu接口外，UE与UE之间还存在PC5通信接口。PC5接口中的传输链路被定义为侧行链路。
资源分配对于PC5接口也十分重要。根据资源分配主体的不同，PC5接口上的资源分配可以分为两种模式(mode)：Mode 1和Mode 2。在Mode 1资源分配模式中，SL传输所使用的时频资源由gNB集中调度；在Mode 2资源分配模式中，SL传输所使用的时频资源是UE通过感知(sensing)周围的时频资源占用情况，然后在网络设备配置的或者预配置的资源池(resource pool)中选择得到的。工作在Mode 1资源分配模式的UE需要在gNB的覆盖范围内，工作在Mode 2资源分配模式的UE可以不在gNB的覆盖范围内，也可以在gNB的覆盖范围内。
对于Mode 2资源分配模式，可以进一步划分为如下四个子类。其中Mode 2(a)是UE基于自身感知选择SL传输所使用的时频资源；Mode 2(b)则是UE辅助其他UE选择SL传输所使用的时频资源。而Mode 2(c)是UE根据配置的，或者预配置的资源池中的一个，或者，多个SL发送图样(pattern)选择SL传输所使用的时频资源；对应的，Mode 2(d)则是UE进行SL传输所使用的时频资源由具有资源调度能力的UE来决定选择的。
如图3所示，Mode 2(b)模式中，发送UE可在向接收UE进行SL数据传输发送之前，根据来自于辅助UE的资源指示信息(或称辅助信息)确定SL数据传输采用的传输资源。其中，发送UE位于辅助UE的覆盖范围内，接收UE作为辅助UE，或者，将接收UE附近的一个或多个UE作为辅助UE。以上发送UE、接收UE或辅助UE中的任意一个或多个，可包括图1和/或图2所示的UE1或UE2。应理解，本申请不限定于图3所示场景，实际中可以包括更多的辅助UE。
如图4所示，Mode 2(b)模式进一步可分为触发方式(trigger-based)和非触发方式(non trigger-based)。基于触发方式情况下，发送UE会在发送周期业务之前主动发送一个触发消息给辅助UE，该触发消息用来指示发送UE的待发送数据的优先级、业务周期以及待发业务数据的大小等信息。这里的辅助UE可以是接收UE或者是接收UE附近的可以用来帮助接收UE确定资源选择的UE。辅助UE接收到该触发消息后，可根据触发消息中所提供的参数来进行辅助资源的选择，例如根据发送UE的待发送数据的优先级通过资源感知来进行资源的筛选和排除，获得辅助资源。当辅助UE选好辅助资源后，将该辅助资源作为资源指示信息反馈给发送UE。在成功接收到来自辅助UE的资源指示信息后，发送UE将结合自身已感知筛选后的候选资源以及辅助UE选择的辅助资源来共同确定最终用于数据传输的传输资源。
应理解，发送UE可根据待发送数据的优先级确定候选资源。比如，根据待发送数据的优先级确定参考信号接收功率(reference signal received power，RSRP)门限，该RSRP门限与待发送数据之间存在映射关系，例如，发送UE配置有优先级与RSRP门限之间的对应关系，在确定候选资源时可查找该对应关系，以确定待发送数据的优先级所对应的RSRP门限。这里待发送数据的优先级可与该数据所属业务有关，或者与发送UE的配置等有关。此后，发送UE可进行资源感知，当感知的资源的RSRP小于(或不超过)此前确定的信号强度的门限时，发送UE将该资源确定为候选资源。此外还应理解，以上辅助 UE根据设定优先级确定辅助资源的方式，可参照发送UE根据待发送数据的优先级确定候选资源的方式。
触发方式情况下，辅助UE是根据触发消息中的发送UE的业务优先级进行资源确定，因此辅助UE所确定的辅助资源与发送UE自身感知确定的资源是满足相同RSRP门限的。如图5所示，可将发送UE根据自己的感知结果所确定的候选传输资源集合记为S T，而辅助UE根据触发消息中指示的优先级来确定的资源集合记为S R。
其中，S T表示这部分资源是在满足待发送数据的优先级的前提下对发送UE和附近周围UE干扰最小的资源集合。相对应的，S R表示这部分资源是在满足待发送数据的优先级的前提下对辅助UE和辅助UE附近周围的UE干扰最小的资源集合。换句话说，S T和S R是基于相同优先级对应的RSRP门限值来筛选确定出来的，在确定最终的传输资源时它们应具有相同的参考权值比重。此时发送UE所对应的用户设备可以优先从S T与S R的交集部分选取资源用于业务数据的传输，此交集部分资源对发送UE和接收UE都是干扰最优的资源选择。当交集部分的资源不能满足传输业务需求时，该用户设备再从S T与S R的非交集部分进行资源选择用于业务数据的传输。
而在非触发方式下，发送UE并不会将相关的业务信息通过触发消息的形式提前发送给辅助UE。辅助UE只能自己预设一些基线参数，其中包括设定优先级。辅助UE根据设定优先级通过资源感知进行辅助资源的确定。在选择出合适的辅助资源后，辅助UE将选择的辅助资源作为资源指示信息反馈给发送UE。在成功接收到来自辅助UE的资源指示信息后，发送UE将结合自身已感知筛选后的候选资源以及辅助UE选择的辅助资源来共同确定最终用于数据传输的传输资源。然而，该设定优先级与发送UE的待发送数据的优先级很可能不一致，发送UE根据该资源指示信息确定的传输资源不符合业务对资源的筛选需求，导致在通过确定的传输资源进行SL数据传输时受到较大的传输干扰。
为了优化非触发方式下辅助UE推荐的辅助资源的准确度，降低发送UE根据辅助资源确定的传输资源进行SL数据传输受到的干扰，本申请实施例提供一种通信方法。该通信方法可由第一终端设备实施。该第一终端设备可包括图1或图2所示UE1和/或UE2，或者，第一终端设备可包括图3的发送UE。
下面以图3所示的发送UE和辅助UE为例，说明本申请实施例提供的通信方法。该方法可包括图6所示的以下步骤：
S101：发送UE接收来自于辅助UE的资源指示信息，该资源指示信息用于指示第一资源以及第一优先级。
其中，第一资源为根据第一优先级确定的，例如，第一资源为辅助UE根据第一优先级确定的资源，该资源可被称为辅助UE的推荐资源，或辅助UE根据第一优先级确定的候选资源。例如，第一优先级为辅助UE的设定优先级，辅助UE根据第一优先级和资源感知结果获得第一资源。应理解，第一优先级可由辅助UE的出厂配置设定或基站配置。第一优先级也可以是辅助UE当前待发送数据的优先级，或辅助UE此前发送的数据的优先级。第一资源也可被称为第一优先级对应的资源。
示例性的，第一资源包括的资源单元由辅助UE根据第一优先级确定，比如，第一资源包括的资源单元为辅助UE确定的RSRP小于(或不超过)第一优先级对应的RSRP门限的资源单元。其中，辅助UE可通过资源感知确定资源单元分别的RSRP，以及根据第一优先级确定该RSRP门限。
如图7所示，资源指示信息可包括比特位图(bitmap)。比特位图可用于指示第一资源包括的资源单元。示例性的，比特位取值为1时，表示该比特位对应的资源单元为第一资源包括的资源单元。此外，也可将比特位取值为0的资源单元作为第一资源包括的资源单元。示例性的，图7所示的比特位图可对应于占用4个时隙且每个时隙上有4个子信道的资源窗，每个比特位对应于该资源窗中的一个子信道。
此外，资源指示信息可包括用于指示第一资源包括的资源单元的索引或时频位置等信息。
应理解，本申请中的资源单元可以是一个子信道。
以上资源指示信息也可被称为辅助信息。
S102：发送UE根据第二优先级确定第二资源。
其中，第二优先级为发送UE的待发送数据的优先级。该第二资源为发送UE根据第二优先级确定的候选资源。第二资源也可被称为第二优先级对应的资源。
示例性的，第二资源包括发送UE根据第二优先级确定的候选资源，比如，第二资源包括发送UE确定的RSRP小于(或不超过)第二优先级对应的RSRP门限的资源单元。其中，发送UE可通过资源感知确定资源单元分别的RSRP，以及根据第二优先级确定该RSRP门限。
以上S101与S102所示步骤之间的时序不做具体限定。比如，发送UE可在接收到资源指示信息后，根据第二优先级确定第二资源，或者，可在根据第二优先级确定第二资源后，接收到资源指示信息。
S103：发送UE在传输资源上发送该待发送数据。其中，传输资源为根据第一优先级、第二优先级、第一资源以及第二资源确定的。
采用以上方法，可由发送UE根据第一优先级、第二优先级、第一资源以及第二资源确定传输资源，并通过传输资源发送待发送数据，其中，第二优先级为待发送数据的优先级，第二资源为根据第二优先级确定的候选资源，第一资源由辅助UE根据第一优先级通过资源感知确定，第一优先级为辅助UE的设定优先级。相比于发送UE仅根据自身感知的候选资源和来自于辅助UE的辅助资源确定传输资源的方式，考虑了第一优先级和第二优先级的取值，因此能够优化传输资源的确定方式，降低发送UE通过确定的传输资源发送数据时受到的干扰。
下面具体说明S103中，传输资源的确定方式。
在一种可能的示例中，发送UE可根据第一资源确定第三资源，并根据第一优先级、第二优先级、第二资源以及第三资源确定传输资源。
示例性的，发送UE可在接收到资源指示信息后，将第一资源包括的全部资源作为第三资源。例如图7所示，若比特位取值为1的资源单元为第一资源包括的资源单元，则发送UE可将这些资源单元作为第三资源。
此外，第三资源为根据该第一优先级和该第二优先级从该第一资源中确定的部分资源。比如。第一资源包括的资源单元的数量与第三资源包括的资源单元的数量之间的差值，是根据第一优先级和第二优先级之间的差值确定的。
发送UE可根据第一优先级的取值(以下称为P1)与第二优先级的取值(以下称为P2)之间的差值确定X的取值，其中，X可表示第一资源包括的资源单元的数量与第三资源包括的资源单元的数量之间的差值，或者表示第一资源包括的资源单元的数量与第三资源包 括的资源单元的数量之间的差值与第一资源包括的资源单元的数量的比值。其中，X的取值是和P1与P2相关联的，或者说，X的取值是根据P1和P2确定的。X与P1和P2之间的关系具体可以表现为函数映射关系，例如X＝f(P1，P2)；或者，X的取值也可以与P1和P2满足映射关系，比如满足图表对应关系。X与P1和P2之间关系的具体表现方式在此不做限定。
示例性的，第一优先级比第二优先级低时，第一优先级的取值与第二优先级的取值之间的差值与X成正相关，也就是说，第一优先级的取值与第二优先级的取值之间相差越大，X取值越大，因此发送UE需要从第一资源包括的资源中排除的资源越多，作为第三资源的资源单元越少；反之，第一优先级的取值与第二优先级的取值之间相差越小，X取值越小，因此发送UE需要从第一资源包括的资源中排除的资源越少，作为第三资源的资源单元越多。应理解，第一优先级比第二优先级低，是指第一优先级的取值P1大于第二优先级的取值P2。
例如，第一优先级比第二优先级低时，若X表示第一资源包括的资源单元的数量与第三资源包括的资源单元的数量之间的差值，且发送UE根据P1以及P2确定X＝3，则如图8所示发送UE需要从第一资源包括的7个资源单元中排除3个资源单元，将剩余的4个资源单元作为第三资源包括的资源单元。其中，图8中通过加粗线框表示的比特位对应的资源单元为第三资源包括的资源单元。
另外，若X表示第一资源包括的资源单元的数量与第三资源包括的资源单元的数量之间的差值与第一资源包括的资源单元的数量的比值，且发送UE根据P1以及P2确定X＝57.14％，则如图8所示发送UE需要从第一资源包括的7个资源单元中排除3个资源单元，将剩余的4个资源单元作为第三资源包括的资源单元。其中，图8中通过加粗线框表示的比特位对应的资源单元为第三资源包括的资源单元。
示例性的，从第一资源包括的资源单元中排除资源单元的方式可以是随机排除，或者是按照资源单元的索引或时频位置按顺序排除，这里不予具体限定。
应理解，方式二中在第一优先级低于第二优先级时，发送UE根据第一优先级与第二优先级的差值从第一资源包括的资源单元中排除部分资源单元，能够降低因为第一优先级较低导致的干扰问题，从而提高SL传输准确性。
基于以上第三资源，这里以第一优先级的取值为P1且第二优先级的取值为P2为例，说明传输资源的确定方式。在P1大于或等于P2的情况下，该传输资源属于第三资源和第二资源的交集。在P1大于或等于P2，且第三资源和第二资源的交集小于待发送数据需要的资源(或者说，该交集包括的资源不足以发该待发送数据)的情况下，传输资源包括交集以及第四资源，该第四资源属于第三资源中除交集以外的剩余资源。在P1大于或等于P2，且第三资源小于待发送数据需要的资源(或者说，该第三资源不足以发该待发送数据)的情况下，传输资源包括第三资源以及第五资源，该第五资源属于该第二资源中除该交集以外的剩余资源。
如图9所示，当发送UE根据图9所示的第二资源和第三资源确定传输资源时，若第一优先级大于或等于第二优先级，则发送UE可优先将第三资源和第二资源的交集(即如图9所示横向阴影表示的优先选择资源)中的部分或全部资源单元作为传输资源，或者说，传输资源属于第三资源和第二资源的交集。在该交集包括的资源小于待发送数据需要的资源时，或者说，在该交集包括的资源单元不足以发送待发送数据时，发送UE将第三资源 和第二资源的交集包括的资源单元作为传输资源，额外将第四资源作为传输资源。其中，第四资源属于第三资源的资源中除该交集以外的剩余资源，例如图9所示，可从竖向阴影表示的次优选择资源中根据待发送数据需要的资源单元的数量选择第四资源作为传输资源。在第三资源小于待发送数据需要的资源时，或者说，第三资源不足以发送待发送数据时，发送UE可将第三资源作为传输资源，额外可以降低无资源作为传输资源。其中，第五资源属于第二资源中除该交集以外的剩余资源，例如图9所示，可从斜向阴影表示的剩余选择资源中根据待发送数据需要的资源单元的数量选择第五资源作为传输资源。
采用图9所示的传输资源确定方式，发送UE能够更为优先地从对应于较高优先级的辅助资源中选择传输资源，因此在第一优先级大于或等于第二优先级时，可以减少SL传输过程中的干扰，能够提高SL传输效率。
此外，在P2大于或等于P1的情况下，传输资源属于第三资源和所述第二资源的交集。在P2大于或等于P1，且第三资源和第二资源的交集小于待发送数据需要的资源的情况下，传输资源可包括该交集以及第六资源，该第六资源属于该第二资源以及该第三资源的并集除该交集以外的剩余资源。
如图10所示，当发送UE根据图10所示的第二资源和第三资源确定传输资源时，若第一优先级小于第二优先级，则发送UE可优先将第三资源和第二资源的交集(即如图10所示横向阴影表示的优先选择资源)中的部分或全部资源单元作为传输资源，或者说，传输资源属于第三资源和第二资源的交集。在该交集包括的资源小于待发送数据需要的资源时，或者说，在该交集包括的资源单元不足以发送待发送数据时，发送UE将第三资源和第二资源的交集包括的资源单元作为传输资源，额外将第六资源作为传输资源。其中，第六资源属于第二资源和第三资源的并集中除该交集以外的剩余资源，例如图10所示，可从竖向阴影表示的次优选择资源中根据待发送数据需要的资源单元的数量选择第六资源作为传输资源。
采用图10所示的传输资源确定方式，能够在第一优先级小于第二优先级时降低SL传输干扰，从而提高SL传输准确性。
再比如图11所示，若第三资源为图8所示的第三资源，该第三资源在图7所示的第一资源的基础上排除了X个(或X％)的资源单元，若第一优先级小于第二优先级，则发送UE可优先将第三资源和第二资源的交集包括的资源单元(即如图11所示横向阴影表示的优先选择资源)作为传输资源。在这部分资源单元的数量少于待发送数据需要的资源单元的数量时，或者说，第三资源和第二资源的交集包括的资源单元不足以发送待发送数据时，发送UE将第三资源和第二资源的交集包括的资源单元作为传输资源，额外可以从第六资源(即第二资源包括的资源单元以及第三资源包括的资源单元中，除第三资源和第二资源的交集包括的资源单元以外的资源单元，如图11所示竖向阴影表示的次优选择资源)中，根据待发送数据需要的资源单元的数量选择部分或全部资源单元作为传输资源。
相比于根据图11确定的传输资源，图11所示的传输资源的确定过程通过排除部分辅助资源来降低因为第一优先级较低导致的干扰问题，从而进一步提高SL传输准确性。
在另一种可能的示例中，除接收到来自于辅助UE的资源指示信息外，若发送UE还接收来自于辅助UE以外的至少一个第三终端设备的资源指示信息，其中，若每个第三终端设备的资源指示信息所指示的优先级与第一优先级相同，则此时，传输资源根据该第一 优先级、该第二优先级、该第一资源以及每个第三终端设备的资源指示信息分别指示的资源和优先级，确定传输资源。
其中，第三终端设备可以与辅助UE相同或不同。
应理解，每个第三终端设备的资源指示信息所指示的资源和优先级之间满足以下关系：该资源是该第三终端设备根据该优先级确定的，根据该优先级确定该资源的方式，可参照本申请中辅助UE根据第一优先级确定第一资源时的说明。
因此，在发送UE接收来自于多个UE(包括辅助UE和至少一个第三终端设备)分别的资源指示信息的情况下，如果多个UE分别的优先级相同，则发送UE可根据每个UE分别指示的资源指示信息、第二优先级和第二资源选择传输资源。
示例性的，发送UE可根据多个UE分别指示的资源(包括第一资源和至少一个第三终端设备各自的资源指示信息分别指示的资源)包括的资源单元中权值不低于第一阈值的至少一个资源单元作为第七资源，并根据第一优先级、第二优先级、第七资源以及第二资源确定传输资源。应理解，资源单元的权值可表征资源单元作为所述传输资源的可能性，比如资源单元的权值越高，则该资源单元作为传输资源的可能性越高。
其中，第一阈值可以是预定义的值，或者可由第一终端设备确定。
如图12所示，假设辅助资源1和辅助资源2分别表示来自于两个第三终端设备的资源指示信息，发送UE可根据第一资源、辅助资源1以及辅助资源2确定每个资源单元的权值。其中，权值的确定方式包括但不限于，根据同一个资源单元对应的比特位分别在第一资源、辅助资源1以及辅助资源2中的取值进行加权平均，比如，若资源单元对应的比特位分别在第一资源、辅助资源1以及辅助资源2中的取值均为1，则该资源单元对应的权值为1。
此外，也可根据资源单元包括在资源指示信息指示的资源的次数，和资源指示信息的总数量，确定资源单元的权重，其中，这里的资源指示信息包括来自于辅助UE和全部第三终端设备的资源指示信息。比如，发送UE接收到来自于辅助UE和两个第三终端设备的资源指示信息，即资源指示信息的总数量为3，资源单元A包括在第一资源和一个第三终端设备的资源指示信息指示的资源中，即资源单元A包括在2个资源指示信息指示的资源中，则可确定资源单元的权值为2/3(或0.667)。
应理解，第一阈值可以是发送UE设定的阈值，或者可由网络设备(如基站)配置。比如图12所示，当第一阈值不高于0.667时，发送UE可将权值不低于0.667的资源单元(即图12中加粗线框表示的资源单元)作为第七资源包括的资源单元。
本申请实施例中，根据第一优先级、第二优先级、第七资源和第二资源确定传输资源的方式，可以参照前述说明的，根据第一优先级、第二优先级、第三资源和第二资源确定传输资源的方式。
具体来说，以第一优先级的取值为P1且第二优先级的取值为P2为例，在P1大于或等于P2的情况下，该传输资源属于第七资源和第二资源的交集。在P1大于或等于P2，且第七资源和第二资源的交集小于待发送数据需要的资源(或者说，该交集包括的资源不足以发该待发送数据)的情况下，传输资源包括交集以及第八资源，该第八资源属于第七资源中除交该集以外的剩余资源。在P1大于或等于P2，且第七资源小于待发送数据需要的资源(或者说，该第七资源不足以发该待发送数据)的情况下，传输资源包括第七资源以 及第九资源，该第九资源属于该第二资源中除该交集以外的剩余资源。具体实现方式的说明可参照图9，这里不再具体展开。
在P2大于或等于P1的情况下，传输资源属于第七资源和所述第二资源的交集。在P2大于或等于P1，且第七资源和第二资源的交集小于待发送数据需要的资源的情况下，传输资源可包括该交集以及第十资源，该第十资源属于该第二资源以及该第七资源的并集除该交集以外的剩余资源。具体实现方式的说明可参照图10，这里不再具体展开。
在一种可能的示例中，若发送UE还接收来自于其他辅助UE(以下称为第四终端设备)的资源指示信息，每个资源指示信息用于指示一个第四终端设备的优先级和根据该优先级确定的资源。则发送UE可在确定第一优先级的取值与第二优先级的取值之间差值的绝对值小于或等于每个资源指示信息指示的优先级的取值与第四优先级的取值之间的差值的绝对值后，根据第一优先级、第二优先级、第一资源和第二资源确定传输资源，以提升根据辅助资源确定传输资源的准确性，降低SL数据传输过程受到的干扰。或者说，S101中涉及的第一优先级为发送UE接收的来自一个或多个其他终端设备(包括辅助UE和上述第四终端设备)的资源指示信息所指示的优先级中与该第二优先级之间差值的绝对值最小的优先级。
应理解，第四终端设备可以与辅助UE相同或不同。
如图13所示，若发送UE在接收资源指示信息的窗口内接收到资源指示信息1、资源指示信息2以及资源指示信息3，其中，资源指示信息1来自于辅助UE，资源指示信息1指示的第一优先级的取值为P1，资源指示信息2指示的优先级的取值为P3，资源指示信息3指示的优先级的取值为P4。则发送UE可在确定P1、自身待发送数据的优先级的取值P2、P3以及P4满足优先级关系时，根据P1、P2、资源指示信息1所指示的第一资源以及第二资源确定待发送数据的传输资源。其中，该优先级关系包括：
|P2-P1|≤|P3-P1|并且|P2-P1|≤|P4-P1|；
或者，该优先级关系可表述为：P1与P2之间的差值的绝对值小于或等于P1与P3之间的差值的绝对值，且P1与P2之间的差值的绝对值小于或等于P1与P4之间的差值的绝对值。
