本申请要求在2022年01月29日提交中国专利局、申请号为202210112597.3、申请名称为“一种通信方法、装置、可读存储介质及芯片系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置、可读存储介质及芯片系统。
背景技术
在无线通信系统中，终端设备与终端设备之间可以借助网络进行数据通信，也可以不借助网络设备而直接进行终端设备与终端设备之间的通信，比如两个终端设备之间可以通过PC5接口直接通信。终端设备与终端设备之间的通信可以称为侧行链路(sidelink，SL)。侧行链路支持单播、组播、广播通信。
侧行链路通信的一个典型应用场景为车联网(vehicle to everything，V2X)技术。V2X是能够将车辆与一切事物相连接的新一代信息通信技术，比如车辆与车辆之间的通信(vehicle-to-vehicle，V2V)、车辆与人之间的通信(vehicle to pedestrian，V2P)、车辆与道路设施之间的通信(vehicle-to-infrastructure，V2I)、车辆与网络之间的通信(vehicle to network，V2N)等。
终端设备可以基于侧行链路的资源进行侧行链路的数据传输。侧行链路的资源可以由终端设备自己确定，也可以由网络设备为终端设备配置。如何更加合理的对侧行链路资源进行调度成为当前亟需解决的问题。
发明内容
本申请实施例提供一种通信方法、装置、可读存储介质及芯片系统，用以向网络设备上报两个制式的资源池的资源重叠的情况，从而使网络设备可以结合这一情况更加合理的调度资源。
第一方面，本申请提供一种通信方法，该方法可以由终端设备或终端设备内部的单元、模块或芯片执行，本申请中第一终端设备为例进行介绍。该方法包括：第一终端设备确定第一资源池的资源和第二资源池的资源重叠，第一资源池包括支持第一制式侧行链路传输的资源，第二资源池包括支持第二制式侧行链路传输的资源。第一终端设备向网络设备发送第一消息。第一消息包括第一指示信息，第一指示信息指示第一资源池的资源和第二资源池的资源重叠。
举个例子，第一制式侧行链路传输为新无线(new radio，NR)侧行链路传输，第一资源池包括NR侧行链路的传输资源。第二制式侧行链路传输为长期演进(long term evolution，LTE)侧行链路传输，第二资源池包括LTE侧行链路的传输资源。第一资源池和第二资源池存在重叠。若网络设备不知道第一资源池和第二资源池存在重叠，则网络设备会不考虑LTE侧行链路传输对第一资源池的资源的占用程度，而是根据NR侧行链路传输对第一资 源池的资源的占用程度为第一终端设备调度NR侧行链路的传输资源。若NR侧行链路传输对第一资源池中的资源占用较少，网络设备可能推断NR侧行链路传输大概率可以得到保障，继而断定第一终端设备的通信性能是很容易满足，因此网络设备在为第一终端设备配置NR侧行链路传输参数时，会配置一些高要求的参数。
但是，若LTE侧行链路传输对第一资源池的资源中的资源占用较多，LTE侧行链路的信道状态较差，或LTE侧行链路的资源情况较差。网络设备在为第一终端设备配置传输参数时若考虑了LTE侧行链路传输对第一资源池的影响，则网络设备可能断定第一终端设备的通信性能不容易满足，因此可能会为第一终端设备配置一些较低要求的参数。
可以看出，本申请中由于终端设备在确定第一资源池的资源和第二资源池的资源重叠的情况下向网络设备发送第一指示信息，从而可以使网络设备根据第一指示信息确定第一资源池的资源和第二资源池的资源重叠，从而使网络设备获知更多的资源相关信息，进而可以为网络设备更加合理的调度资源提供帮助，比如网络设备可以基于第一指示信息更加合理的为终端设备调度资源。
本申请中，第一指示信息的具体实现形式可以由多种，比如在一种可能的实施方式中，第一指示信息包括：指示第一资源池的资源和第二资源池的资源重叠的指示信息。
由于网络设备可以基于第一指示信息确定第一资源池的资源和第二资源池的资源重叠，如此，网络设备在为第一制式侧行链路传输调度资源时可以基于这一因素进行调度，进而以更加合理的为终端设备调度资源。
又一种可能的实施方式中，第一指示信息包括：指示第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰的指示信息。
比如，第一指示信息包括：指示第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰的指示信息。
如此，网络设备不仅可以基于第一指示信息确定第一资源池的资源和第二资源池的资源重叠，还可以确定第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰，如此，网络设备可以获知更多的信息，进而可以更加合理的为终端设备调度资源。
再比如，第一指示信息包括：指示第一资源池的资源受到第二制式侧行链路传输的干扰的指示信息。
如此，网络设备不仅可以基于第一指示信息确定第一资源池的资源和第二资源池的资源重叠，还可以确定第一资源池的资源受到第二制式侧行链路传输干扰，如此，网络设备可以获知更多的信息，进而可以更加合理的为终端设备调度资源。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以接收来自网络设备的第一配置信息，第一配置信息包括允许发送第一指示信息的指示信息。
如此，可以使得第一终端设备需在网络设备允许其发送第一指示信息的情况下才可以发送第一指示信息，从而可以提高网络设备可以对第一终端设备的可管控程度，增大网络设备可以对第一终端设备进行管控的范围。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以确定第一信道忙碌率；第一信道忙碌率指示第二制式侧行链路传输对第一资源池的资源的影响程度。第一终端设备向网络设备发送第一消息，还包括：第一终端设备至少根据第一信道忙碌率，向网络设备发送第一消息。
由于根据第二制式侧行链路传输对第一资源池的资源的影响程度，向网络设备发送第一消息，因此发送的第一消息也可以指示出第二制式侧行链路传输对第一资源池的资源的影响程度，进而网络设备可以基于这一信息更加合理的为终端设备调度资源。
在一种可能的实施方式中，第一信道忙碌率根据第一目标子信道在第一资源池的子信道的占比确定，第一目标子信道包括第一资源池和第二资源池的重叠资源中第二制式侧行链路传输对应的接收信号强度大于第一信号强度阈值的子信道。
本申请第一信道忙碌率可以反映出第二制式侧行链路传输对整个第一资源池的资源的影响程度。当网络设备接收到第一指示信息，则说明第二制式侧行链路传输对整个第一资源池的资源的影响程度较大或较小(满足第一触发事件组中的至少一个事件)，进而网络设备可以更加合理的对第一资源池中的资源进行调度，也可以为第一终端设备配置更加合理的第一侧行链路传输参数。又一种可能的实施方式中，当网络设备接收到该第一信道忙碌率，由于第一信道忙碌率指示第二制式侧行链路传输对整个第一资源池的资源的影响程度，因此网络设备可以根据第一信道忙碌率更加合理的对第一资源池中的资源进行调度，也可以为第一终端设备配置更加合理的第一侧行链路传输参数。
在一种可能的实施方式中，第一信道忙碌率根据第一目标子信道在第一资源池与第二资源池的重叠资源的子信道的占比确定。
本申请第一信道忙碌率可以反映出第二制式侧行链路传输对第一资源池与第二资源池的重叠资源的影响程度。当网络设备接收到第一指示信息，则说明第二制式侧行链路传输对第一资源池与第二资源池的重叠资源的影响程度较大或较小(满足第一触发事件组)，进而网络设备可以更加合理的对第一资源池与第二资源池的重叠资源中的资源进行调度，也可以为第一终端设备配置更加合理的第一侧行链路传输参数。又一种可能的实施方式中，当网络设备接收到该第一信道忙碌率，由于第一信道忙碌率指示第二制式侧行链路传输对第一资源池与第二资源池的重叠资源的影响程度，因此网络设备可以根据第一信道忙碌率更加合理的对第一资源池与第二资源池的重叠资源进行调度，也可以为第一终端设备配置更加合理的第一侧行链路传输参数。
在一种可能的实施方式中，第一信道忙碌率根据第四信道忙碌率确定，第四信道忙碌率指示第二制式侧行链路传输对第二资源池的资源的影响程度。
如此，可以多提供一种确定第一信道忙碌率的方法，从而在第一终端设备无法得到较为准确的第一信道忙碌率的情况下，也可以基于第四信道忙碌率确定第二制式侧行链路传输对第一资源池的资源的影响程度，继而可以降低对第一终端设备能力的要求，可以增加本申请的适用场景。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设 备还可以确定第一信道忙碌率大于第一忙碌率阈值；或，第一终端设备确定第一信道忙碌率小于第二忙碌率阈值。
由于第一终端设备可以在第一信道忙碌率满足一定的条件的情况下才发送第一消息，如此，可以减少网络设备接收到的信息的数量，节省信令传输所消耗的资源。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以接收来自网络设备的第二配置信息，第二配置信息包括第一忙碌率阈值和/或第二忙碌率阈值。
一种可能的实施方式中，第二配置信息可以作为第一配置信息的一种可能的实施方式，比如第二配置信息与第一配置信息可以为同一个信息，再比如第二配置信息可以包括第一配置信息。比如，当第一终端设备从网络设备接收到第二配置信息，则可以确定网络设备允许第一终端设备发送第一指示信息。如此，可以多提供一种网络设备向终端设备指示允许其上报第一指示信息的方式。
进一步，第二配置信息中包括的第一忙碌率阈值和/或第二忙碌率阈值还可以为第一指示信息上报前需要满足的条件，而由于第一终端设备可以在第一信道忙碌率满足一定的条件的情况下才发送第一消息，如此，可以减少网络设备接收到的信息的数量，节省信令传输所消耗的资源。
在一种可能的实施方式中，第一消息包括第一信道忙碌率。
如此，网络设备可以根据第一信道忙碌率确定第二制式侧行链路传输对第一资源池的资源的影响程度。比如，当第二制式侧行链路传输对第一资源池的资源的影响程度较大的情况，在为第一终端设备的第一制式侧行链路传输配置传输参数时，可以将第二制式侧行链路传输对第一资源池的影响程度这一因素的重要性提高。再比如，当第二制式侧行链路传输对第一资源池的资源的影响程度较小的情况，在为第一终端设备的第一制式侧行链路传输配置传输参数时，可以将第二制式侧行链路传输对第一资源池的影响程度这一因素的重要性降低。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以确定第二信道忙碌率，第二信道忙碌率指示第一制式侧行链路传输对第一资源池的资源的影响程度。第一终端设备向网络设备发送第一消息，还包括：第一终端设备至少根据第二信道忙碌率，向网络设备发送第一消息。
由于根据第一制式侧行链路传输对第一资源池的资源的影响程度，向网络设备发送第一消息，因此发送的第一消息也可以指示出第一制式侧行链路传输对第一资源池的资源的影响程度，进而网络设备可以基于这一信息更加合理的为终端设备调度资源。
在一种可能的实施方式中，第二信道忙碌率根据第二目标子信道在第一资源池的子信道中的占比确定。第二目标子信道包括第一资源池中第一制式侧行链路传输对应的接收信号强度大于第二信号强度阈值的子信道。
如此，第二信道忙碌率可以较为准确的反映第一制式侧行链路传输对第一资源池的资源的影响程度。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以确定第二信道忙碌率大于第三忙碌率阈值。或者，又一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以确定第二信道忙碌率小于第四忙碌率阈值。
由于第一终端设备可以在第二信道忙碌率满足一定的条件的情况下才发送第一消息，如此，可以减少网络设备接收到的信息的数量，节省信令传输所消耗的资源。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以接收来自网络设备的第三配置信息，第三配置信息包括第三忙碌率阈值和/或第四忙碌率阈值。
一种可能的实施方式中，第三配置信息可以作为第一配置信息的一种可能的实施方式，比如第三配置信息与第一配置信息可以为同一个信息，再比如第三配置信息可以包括第一配置信息。比如，当第一终端设备从网络设备接收到第三配置信息，则可以确定网络设备允许第一终端设备发送第一指示信息。如此，可以多提供一种网络设备向终端设备指示允许其上报第一指示信息的方式。
进一步，第三配置信息中包括的第三忙碌率阈值和/或第四忙碌率阈值还可以为第一指示信息上报前需要满足的条件，而由于第一终端设备可以在第一信道忙碌率满足一定的条件的情况下才发送第一消息，如此，可以减少网络设备接收到的信息的数量，节省信令传输所消耗的资源。
在一种可能的实施方式中，第一消息包括第二信道忙碌率。
如此，可以与现有标准更加兼容，比如，当现有标准中网络设备请求终端设备上报第二信道忙碌率的情况下，终端设备可以将第一指示信息等一起上报至网络设备，以便网络设备可以得知更多的信息，进而更加合理的为第一制式侧行链路传输调度资源。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以确定第三信道忙碌率，第三信道忙碌率指示第一制式侧行链路传输以及第二制式侧行链路传输对第一资源池的资源的影响程度。第一终端设备向网络设备发送第一消息，还包括：第一终端设备至少根据第三信道忙碌率，向网络设备发送第一消息。
由于根据第一制式侧行链路传输以及第二制式侧行链路传输对第一资源池的资源的影响程度，向网络设备发送第一消息，因此发送的第一消息也可以指示出第一制式侧行链路传输以及第二制式侧行链路传输对第一资源池的资源的影响程度，进而网络设备可以基于这一信息更加合理的为终端设备调度资源。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前，第一终端设备还可以确定第三信道忙碌率大于第五忙碌率阈值；或，第一终端设备确定第三信道忙碌率小于第六忙碌率阈值。
由于第一终端设备可以在第三信道忙碌率满足一定的条件的情况下才发送第一消息，如此，可以减少网络设备接收到的信息的数量，节省信令传输所消耗的资源。
在一种可能的实施方式中，第一终端设备向网络设备发送第一消息之前第一终端设备还可以接收来自网络设备的第四配置信息，第四配置信息包括第五忙碌率阈值和/或第六忙碌率阈值。
一种可能的实施方式中，第四配置信息可以作为第一配置信息的一种可能的实施方式，比如第四配置信息与第一配置信息可以为同一个信息，再比如第四配置信息可以包括第一配置信息。比如，当第一终端设备从网络设备接收到第四配置信息，则可以确定网络设备允许第一终端设备发送第一指示信息。如此，可以多提供一种网络设备向终端设备指示允许其上报第一指示信息的方式。
进一步，第四配置信息中包括的第五忙碌率阈值和/或第六忙碌率阈值还可以为第一指示信息上报前需要满足的条件，而由于第一终端设备可以在第一信道忙碌率满足一定的条件的情况下才发送第一消息，如此，可以减少网络设备接收到的信息的数量，节省信令传输所消耗的资源。
在一种可能的实施方式中，第一消息包括第三信道忙碌率。
如此，网络设备可以根据第三信道忙碌率确定第一制式侧行链路传输和第二制式侧行链路传输对第一资源池的资源的影响程度。如此，可以更加合理的为第一制式侧行链路传输调度资源。
在一种可能的实施方式中，第三信道忙碌率包括：第一信道忙碌率和第二信道忙碌率的平均值。
由于第一信道忙碌率可以反映第二制式侧行链路传输对第一资源池的资源的影响程度，第二信道忙碌率可以反映第一制式侧行链路传输对第一资源池的资源的影响程度，因此可以通过对第一信道忙碌率和第二信道忙碌率的计算得到第三信道忙碌率。比如将第一信道忙碌率和第二信道忙碌率的平均值作为第三信道忙碌率，该方案可以降低第三信道忙碌率的计算复杂度。
在一种可能的实施方式中，第三信道忙碌率包括第一信道忙碌率和第二信道忙碌率的加权平均值。
由于为第一信道忙碌率和第二信道忙碌率设置了权重，因此可以提高第三信道忙碌的准确度。
在一种可能的实施方式中，第三信道忙碌率包括第三目标子信道的数量在第一资源池的子信道中的占比。其中，第三目标子信道包括第一资源池中满足以下内容中至少一项的子信道：第一制式侧行链路传输对应的接收信号强度大于第三信号强度阈值；或，第二制式侧行链路传输对应的接收信号强度大于第四信号强度阈值。
也可以理解为，本申请实施中针对第一资源池中的一个子信道，当第一终端设备确定该子信道的第一制式侧行链路传输对应的接收信号强度大于第三信号强度阈值，和/或，该子信道的第二制式侧行链路传输对应的接收信号强度大于第四信号强度阈值，则第一终端设备确定该子信道为第三目标子信道。
由于可以通过统计第三目标子信道的数量在第一资源的子信道中的占比确定第三信 道忙碌率，因此得到的第三信道忙碌率可以更加准确的反映出第一制式侧行链路传输以及第二制式侧行链路传输对第一资源池的资源的影响程度。
在一种可能的实施方式中，当第三信道忙碌率包括第一信道忙碌率和第二信道忙碌率的加权平均值：第一信道忙碌率的权重根据第一资源池与第二资源池的重叠资源在第一资源池中的占比确定。
由于加入了第一资源池与第二资源池的重叠资源在第一资源池中的占比作为权重，因此得到的第三信道忙碌率可以更加准确的反映出第一制式侧行链路传输以及第二制式侧行链路传输对第一资源池的资源的影响程度。
在一种可能的实施方式中，第一终端设备确定第一资源池的资源和第二资源池的资源重叠，第一终端设备还可以接收第三消息，第三消息包括第二指示信息，第二指示信息指示第一资源池的资源和第二资源池的资源重叠。第一终端设备根据第二指示信息，确定第一资源池的资源和第二资源池的资源重叠。
当第一终端设备无法确定第一资源池的资源和第二资源池的资源是否重叠的情况下，可以根据其他终端设备发送的信息确定第一资源池的资源和第二资源池的资源是否重叠。如此，当第一终端设备能力有限，比如无法确定第一资源池的资源和第二资源池的资源是否重叠的情况下，也可以应用本申请提供的方案，如此可以降低对第一终端设备的要求。
进一步，在一种可能的实施方式中，第一终端设备接收第三消息之前，第一终端设备还可以发送第二消息，第二消息请求查询第一资源池的资源和第二资源池的资源是否重叠。
当第一终端设备无法确定第一资源池的资源和第二资源池的资源是否重叠的情况下，可以向其他终端设备查询第一资源池的资源和第二资源池的资源是否重叠，如此，其他终端设备反馈至第一终端设备的信息可以与第一终端设备实际需要的信息更加匹配。
在一种可能的实施方式中，第二指示信息包括：指示第一资源池的资源和第二资源池的资源重叠的指示信息。
如此，第一终端设备可以基于第二指示信息确定第一资源池的资源和第二资源池的资源重叠，进而可以向网络设备上报第一指示信息，以使网络设备更加合理的为终端设备调度资源。
在一种可能的实施方式中，第二指示信息包括指示第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰的指示信息。
如此，第一终端设备可以基于第二指示信息确定第一资源池的资源和第二资源池的资源重叠，还可以确定第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输的干扰，如此，第一终端设备也可以向网络设备上报指示第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰的指示信息，如此，网络设备可以获知更多的信息，进而可以更加合理的为终端设备调度资源。
在一种可能的实施方式中，第二指示信息包括指示第一资源池受到第二制式侧行链路传输的干扰的指示信息。

如此，在第一终端设备无法得到较为准确的第一信道忙碌率的情况下，也可以基于第四信道忙碌率确定第二制式侧行链路传输对第一资源池的资源的影响程度，继而可以降低对第一终端设备能力的要求，可以增加本申请的适用场景。
在一种可能的实施方式中，第四信道忙碌率根据第二资源池中第二制式侧行链路传输对应的接收信号强度大于第五信号强度阈值的子信道在第二资源池的子信道中的占比。
如此，第四信道忙碌率可以更准确的反映出第二制式侧行链路传输对第二资源池的资源的影响程度。

由于第一终端设备可以在第二信道忙碌率满足一定的条件的情况下才发送第二消息，如此，可以减少信令交互，节省信令传输所消耗的资源。
在一种可能的实施方式中，第一消息还包括：第一资源池与第二资源池的重叠资源的时域信息和/或频域信息。
网络设备可以确定出第一资源池和第二资源池中具体哪些资源重叠，进而在为第一终端设备调度第一资源池的资源时可以更加合理的调度。比如，第一资源池支持NR侧行链路传输，第二资源池支持LTE侧行链路传输，若LTE侧行链路对第一资源池和第二资源 池的重叠资源占用较多，则网络设备可以尽量为第一终端设备的NR侧行链路调度第一资源池中除该重叠资源之外的资源，从而可以尽量避免为第一终端设备调度的NR侧行链路的资源与LTE侧行链路所占用的资源发生冲突的问题。
在一种可能的实施方式中，第一消息还包括：第一资源池的标识指示信息。
如此，网络设备可以根据第一资源池的标识指示信息确定出第一资源池，进而可以至少确定出具体哪一个资源池的资源与其他资源池的资源重叠。在一种可能的实施方式中，第一资源池的标识指示信息包括以下内容中的至少一项：第一资源池的标识；第一资源池的载波信息；或，第一资源池的BWP信息。

本申请实施例中的网络设备，是网络中用于将终端设备接入到无线网络的设备。网络设备可以为无线接入网中的节点，又可以称为基站，还可以称为无线接入网(radio access network，RAN)节点(或设备)。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。网络设备还可协调对空口的属性管理。例如，网络设备可以包括长期演进(long term evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(5th generation，5G)新无线(new radio，NR)系统中的下一代节点B(next generation node B，gNB)，或者还可以包括传输接收点(transmission reception point，TRP)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或WiFi接入点(access point，AP)等，再或者还可以包括云接入网(cloud radio access network，CloudRAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。再例如，一种V2X技术中的网络设备为路侧单元(road side unit，RSU)，RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其它实体交换消息。图1a中以网络设备为基站为例进行展示。
进一步地，该通信系统100中还包括应用服务器。该通信系统100中包含两种通信接口：PC5接口和Uu接口。
其中，PC5接口是指终端设备与终端设备之间的直连通信接口，终端设备与终端设备之间的直连通信链路即为侧行链路，用于终端设备与终端设备之间的通信。基于侧行链路的通信可以使用如下信道中的至少一个：物理侧行链路共享信道(physical sidelink shared channel，PSSCH)，用于承载数据(data)；物理侧行链路控制信道(physical sidelink control channel，PSCCH)，用于承载侧行链路控制信息(sidelink control information，SCI)，SCI也称为调度分配(scheduling assigment，SA)。
Uu接口是终端设备与网络设备之间的通信接口，终端设备与网络设备之间的通信链路包括上行链路(uplink，UL)和下行链路(downlink，DL)。基于Uu接口的通信可以为，发送方终端设备将数据通过Uu接口发送至网络设备，通过网络设备发送至应用服务器进行处理后，再由应用服务器将处理后的数据下发至网络设备，并通过网络设备发送给接收方终端设备。
需要说明的是，在基于Uu接口的通信方式下，转发发送方终端设备至应用服务器的上行数据的网络设备和转发应用服务器下发至接收方终端设备的下行数据的网络设备可以是同一个网络设备，也可以是不同的网络设备，具体可以由应用服务器决定。
本申请实施例中涉及到的终端设备之间进行侧行链路传输的场景有多种，图1b示例性示出了本申请实施例终端设备侧行链路的又一种可能的应用场景的示意图，如图1b所示，终端设备之间的侧行链路传输还可以包括侧行链路终端设备-网络设备中继(sidelink UE-to-Network Relay)场景中远端终端设备(remote UE)和中继终端设备(relay UE)之间的传输。

本申请实施例提供的方案中涉及到的第一终端设备的第一制式侧行链路或第二制式侧行链路可以为前述图1a所示的V2X UE1与V2X UE2之间的侧行链路，也可以为图1b所示的场景中远端终端设备(remote UE)和中继终端设备(relay UE)之间的侧行链路，还可以为图1c中源端终端设备(source UE)和中继终端设备(relay UE)之间的侧行链路，还可以为图1c中继终端设备(relay UE)和目的终端设备(target UE)之间的侧行链路。
本申请实施例提供的方案中涉及到的第一终端设备和第二终端设备之间基于侧行链路进行的传输可以为前述图1a所示的V2X UE1与V2X UE2之间的侧行链路传输，也可以为图1b所示的场景中远端终端设备(remote UE)和中继终端设备(relay UE)之间的侧行链路传输，还可以为图1c中源端终端设备(source UE)和中继终端设备(relay UE)之间的侧行链路传输，还可以为图1c中继终端设备(relay UE)和目的终端设备(target UE)之间的侧行链路传输。
为了更好的理解本申请实施例的方案，下面对本申请实施例涉及到技术术语进行介绍。
1)资源配置模式。
资源配置模式，也称资源分配模式。一个终端设备可以使用一种或两种资源配置模式。
(1.1)第一种资源配置模式。
第一种资源配置模式为终端设备在侧行链路上进行数据传输的资源是由网络设备进行调度分配的。例如，LTE V2X系统中定义的资源配置模式Mode 3和NR V2X系统中定义的资源配置模式Mode 1。
网络设备可以通过下行控制信息(downlink control information，DCI)给终端设备调度SL资源，或者通过无线资源控制(radio resource control，RRC)消息给终端设备配置SL配置授权(configured grant)，终端设备可以直接使用SL配置授权进行侧行链路传输，或者终端设备在SL配置授权被下行控制信息(Downlink control information，DCI)激活后再使用该SL配置授权进行侧行链路传输。
(1.2)第二种资源配置模式。
第二种资源配置模式为终端设备在侧行链路上进行数据传输的资源是终端设备从配置的资源池中动态选择的。例如，LTE V2X系统中定义的资源配置模式Mode 4和NR V2X系统中定义的资源配置模式Mode 2。
资源池可以是网络设备通过系统广播消息或RRC消息为终端设备配置的，也可以是预配置在终端设备侧的。终端设备发送数据时，可通过随机选择资源，也可以基于侦听(sensing)预留机制或基于部分侦听(partial sensing)预留机制自主地从资源池中选择资源来发送数据。
2)终端设备的状态。
终端设备可具有RRC连接态(RRC_CONNECTED)、RRC空闲态(RRC_IDLE)和RRC非激活态(RRC_INACTIVE)三种RRC连接状态。
RRC连接态与RRC空闲态、RRC非激活态之间可以相互转换，但RRC空闲态与RRC 非激活态之间只能由RRC非激活态转换为RRC空闲态。
此外，根据终端设备是否位于网络设备覆盖范围内，还可分为覆盖范围内(in-coverage，IC)的终端设备和覆盖范围外(out-of-coverage，OOC)的终端设备。只有处于网络设备覆盖范围内的终端设备才有各种RRC连接状态，位于网络设备覆盖范围外的终端设备无法与网络设备直接交互。
可以采用上述第一种资源配置模块选择资源的终端设备为处于RRC连接态的终端设备。可以采用上述第二种资源配置模块选择资源的终端设备可以为处于RRC连接态、RRC非激活态、RRC空闲态或OOC态的终端设备。处于RRC连接态的终端设备可以使用第一种资源配置模式或第二种资源配置模式，甚至可以同时使用这两种资源配置模式，具体使用哪种资源配置模式由网络设备决定。
3)第一资源池和第二资源池。
本申请实施例涉及多个资源池，比如第一资源池、第二资源池。本申请实施例的一个资源池可以包括一个资源或多个资源的集合。资源池中的资源也可以称为时域资源、频域资源或时频域资源。时频域资源是指时域资源和频域资源。
本申请实施例中当多个资源池中的资源重叠时，终端设备可以向网络设备进行上报。该多个资源池可以为两个资源池也可以为三个资源池或更多的资源池，本申请实施例对发生资源重叠情况的资源池的数量不做限定，为了更清楚的介绍，本申请实施例中以第一资源池和第二资源池为例进行介绍。
第一资源池可以包括第一制式侧行链路传输的资源。第一制式侧行链路传输资源用于第一制式的侧行链路的数据和/或信令传输。本申请实施例中第一资源池可以包括一个资源池。又一种可能的实施方式中，第一资源池可以为一个较为上位的概念，第一资源池可以包括多个资源池，第一资源池中包括的多个资源池中的每个资源池至少可以支持第一制式侧行链路传输。又一种可能的实施方式中，第一资源池中包括的多个资源池中的每个资源池中的每个资源至少可以支持第一制式侧行链路传输。
第二资源池可以包括第二制式侧行链路传输的资源。第二制式侧行链路传输资源用于第二制式的侧行链路的数据和/或信令传输。本申请实施例中第二资源池可以包括一个资源池。又一种可能的实施方式中，第二资源池可以为一个较为上位的概念，第二资源池可以包括多个资源池，第二资源池中包括的多个资源池中的每个资源池至少可以支持第二制式侧行链路传输。又一种可能的实施方式中，第二资源池中包括的多个资源池中的每个资源池中的每个资源至少可以支持第二制式侧行链路传输。
第一制式与第二制式可以为两种不同的通信制式，比如第一制式为NR制式，第二制式为LTE制式。再比如，第一制式为LTE制式，第二制式为NR制式。本申请实施例中以第一制式为NR制式，第二制式为LTE制式为例进行介绍。
4)第一资源池和第二资源池的关系。
一种可能的实施方式中，第一资源池和第二资源池的资源可以实现隔离，也可以资源重叠。图2示例性示出了三种可能的资源池的情况示意图，下面结合图2进行介绍。
如图2中的(a)所示，第一资源池和第二资源池的资源可以实现隔离，即第一资源池的中的任一个资源与第二资源池中的任一个资源不会发生资源重叠的情况。比如，网络 设备可以通过频分或者时分的方法配置第一资源池的资源以及第二资源池的资源，且配置的第一资源池的资源和第二资源池的资源正交隔离。这种情况下，第一资源池的全部资源支持第一制式侧行链路传输，但不支持第二制式侧行链路传输；第二资源池的全部资源支持第二制式侧行链路传输，但不支持第一制式侧行链路传输。
如图2中的(b)、(c)、(d)、(e)、(f)和(g)所示，第一资源池的资源和第二资源池的资源重叠。
如图2中的(b)所示，第一资源池中的部分资源与第二资源池中的部分资源重叠。这种情况下，第一资源池中还包括与第二资源池的资源不重叠的资源，且第二资源池中也包括与第一资源池的资源不重叠的资源。举个例子，如图2中的(b)所示，第一资源池的资源可以划分为两部分，分别称为资源A 1和资源A 2，第二资源池的资源也可以划分为两部分，分别称为资源B 1和资源B 2。资源A 2中的全部资源与资源B 2中的全部资源相同。资源A 1中的任一个资源与资源B 1中的任一个资源不同。资源A 2(或者资源B 2)也可以称为第一资源池的资源与第二资源池的资源发生资源重叠的资源，或称为第一资源池的资源与第二资源池的资源的重叠资源。
其中，资源A 1和资源A 2的资源可以是支持第一制式侧行链路传输的资源，资源A 2的资源还支持第二制式侧行链路传输的资源，资源A 1的资源不支持第二制式侧行链路传输的资源。类似的，资源B 1和资源B 2的资源可以是支持第二制式侧行链路传输的资源，资源B 2的资源还支持第一制式侧行链路传输的资源，资源B 1的资源不支持第一制式侧行链路传输的资源。
也可以说，第一资源池的资源与第二资源池的资源的重叠资源为第一资源池中的部分资源。第一资源池的资源与第二资源池的资源的重叠资源为第二资源池中的部分资源。
如图2中的(c)所示，第二资源池的全部资源为第一资源池的全部资源中的部分资源。这种情况下，第二资源池的全部资源除了支持第二制式侧行链路传输的资源之外，还全部支持第一制式侧行链路传输的资源。而第一资源池的全部资源中的一部分资源既支持第一制式侧行链路传输，也支持第二制式侧行链路传输；第一资源池的全部资源中的另一部分资源支持第一制式侧行链路传输，但不支持第二制式侧行链路传输。第一资源池的资源与第二资源池的资源的重叠资源为第二资源池中的全部资源。
如图2中的(d)所示，第一资源池的全部资源为第二资源池的全部资源中的部分资源。这种情况下，第一资源池的全部资源除了支持第一制式侧行链路传输的资源之外，还全部支持第二制式侧行链路传输的资源。而第二资源池的全部资源中的一部分资源既支持第二制式侧行链路传输，也支持第一制式侧行链路传输；第二资源池的全部资源中的另一部分资源支持第二制式侧行链路传输，但不支持第一制式侧行链路传输。第一资源池的资源与第二资源池的资源的重叠资源为第一资源池中的全部资源。
如图2中的(e)所示，第一资源池的全部资源为第二资源池的全部资源。这种情况下，也可以将第一资源池和第二资源池均称为共享资源池，即共享资源池即为第一资源池，也为第二资源池，也可以称为第一资源池和第二资源池的全部资源重叠。第一资源池的全部资源除了支持第一制式侧行链路传输的资源之外，还全部支持第二制式侧行链路传输的资源。而第二资源池的全部资源除了支持第二制式侧行链路传输之外，也支持第一制式侧行链路传输。
本申请实施例中第一资源池可以包括一个资源池。又一种可能的实施方式中，第一资源池可以为一个较为上位的概念，第一资源池可以包括多个资源池，其中第一资源池中包括的多个资源池中的每个资源池中的每个资源至少可以支持第一制式侧行链路传输。一种可能的实施方式中，针对一个资源池，当该资源池的所有资源均至少支持第一制式侧行链路传输的情况下，可以将该资源池称为第一资源池。需要注意的是，当一个资源池被称为第一资源池的情况下，该资源池可能也会有其他名称，比如也有可能被称为第二资源池，比如图2中的(e)所示，共享资源池被称为第一资源池，也被称为第二资源池。
图2中的(f)给出了一种可能的示例，资源池C1、资源池C2和资源池C3中的每个资源池中的至少可以支持第一制式侧行链路传输。资源池C1、资源池C2和资源池C3中的每个资源池中均存在部分支持第二制式侧行链路传输的资源，而且资源池C1、资源池C2和资源池C3中的每个资源池中也均存在部分不支持第二制式侧行链路传输的资源。可以说，资源池C1、资源池C2和资源池C3中的每个资源池中的部分资源均与第二资源池的部分资源重叠。
如图2中的(f)所示，第一资源池可以为资源池C1、资源池C2和资源池C3中的任一个资源池。再比如，第一资源池也可以为资源池C1、资源池C2和资源池C3中的多个资源池。举个例子，当第一资源池为资源池C1、资源池C2和资源池C3，则第一资源池的资源为资源池C1、资源池C2和资源池C3的所有资源的集合。
值得说明的是，图2中的(f)是以资源池C1、资源池C2和资源池C3中的每个资源池中的部分资源均与第二资源池的部分资源重叠为例进行展示的，也有可能资源池C1、资源池C2和资源池C3中的一个或多个资源池中的全部资源与第二资源池的部分或全部资源重叠，本申请实施例不做限制。
本申请实施例中第二资源池可以包括一个资源池。又一种可能的实施方式中，第二资源池可以为一个较为上位的概念，第二资源池可以包括多个资源池，其中第二资源池中包括的多个资源池中的每个资源池中的每个资源至少可以支持第二制式侧行链路传输。一种可能的实施方式中，针对一个资源池，当该资源池的所有资源均至少支持第二制式侧行链路传输的情况下，可以将该资源池称为第二资源池。需要注意的是，当一个资源池被称为第二资源池的情况下，该资源池可能也会有其他名称，比如也有可能被称为第一资源池，比如图2中的(e)所示，共享资源池被称为第二资源池，也被称为第一资源池。
图2中的(g)给出了一种可能的示例，资源池D1、资源池D2和资源池D3中的每个资源池中的至少可以支持第二制式侧行链路传输。资源池D1、资源池D2和资源池D3中的每个资源池中均存在部分支持第一制式侧行链路传输的资源，而且资源池D1、资源池D2和资源池D3中的每个资源池中也均存在部分不支持第一制式侧行链路传输的资源。可以说，资源池D1、资源池D2和资源池D3中的每个资源池中的部分资源均与第一资源池的部分资源重叠。
如图2中的(g)所示比如，第二资源池可以为资源池D1、资源池D2和资源池D3中的任一个资源池。再比如，第二资源池也可以为资源池D1、资源池D2和资源池D3中的多个资源池。举个例子，当第二资源池为资源池D1、资源池D2和资源池D3，则第二资源池的资源为资源池D1、资源池D2和资源池D3的所有资源的集合。
值得说明的是，图2中的(g)是以资源池D1、资源池D2和资源池D3中的每个资源 池中的部分资源均与第一资源池的部分资源重叠为例进行展示的，也有可能资源池D1、资源池D2和资源池D3中的一个或多个资源池中的全部资源与第一资源池的部分或全部资源重叠，本申请实施例不做限制。
本申请实施例中提到的第一资源池的资源和第二资源池的资源重叠可以为图2中的(b)、(c)、(d)、(e)、(f)和(g)的任意一种情况。
值得说明的是，本申请实施例以第一制式和第二制式为例进行介绍，实际应用中，第一资源池的资源可能还支持第三制式侧行链路传输，第二资源池的资源可能还支持第四制式侧行链路传输，本申请实施例中不做限制。

本申请实施例中第一终端设备可以为支持第一制式侧行链路传输和第二制式侧行链路传输的终端设备，比如第一终端设备包括第一制式侧行链路传输通信模块，还包括第二制式侧行链路传输通信模块。本申请实施例中第一制式侧行链路传输通信模块用于第一制式侧行链路传输的通信。本申请实施例中第二制式侧行链路传输通信模块用于第二制式侧行链路传输的通信。
本申请实施例中第一终端设备可以为支持第一制式侧行链路传输，不支持第二制式侧行链路传输的终端设备，比如第一终端设备包括第一制式侧行链路传输通信模块，不包括第二制式侧行链路传输通信模块。
本申请实施例中网络设备比如可以为支持第一制式侧行链路传输，不支持第二制式侧行链路传输的网络设备。或者，网络设备可以为支持第一制式侧行链路传输，也支持第二制式侧行链路传输的网络设备。
如图3所示，该方法包括：
步骤301，第一终端设备确定第一资源池的资源和第二资源池的资源重叠，第一资源池包括支持第一制式侧行链路传输的资源，第二资源池包括支持第二制式侧行链路传输的资源。
步骤302，第一终端设备向网络设备发送第一消息；第一消息包括第一指示信息，第一指示信息指示第一资源池的资源和第二资源池的资源重叠。
相对应的，网络设备接收第一消息。
一种可能的实施方式中，第一消息可以为侧行链路用户设备信息(sidelink UE information，SUI)消息或用户设备辅助信息(UE assistance information，UAI)消息。
步骤303，网络设备根据第一指示信息，确定第一资源池的资源和第二资源池的资源重叠。
由于第一终端设备在确定第一资源池的资源和第二资源池的资源重叠的情况下向网络设备发送第一指示信息，从而可以使网络设备根据第一指示信息确定第一资源池的资源和第二资源池的资源重叠，从而使网络设备获知更多的资源相关信息，进而可以为网络设备更加合理的调度资源提供帮助，比如网络设备可以基于第一指示信息更加合理的为第一终端设备分配资源。
为了进一步说明本申请实施例带来的有益效果，下面介绍一个示例：
该示例中，第一制式侧行链路传输为NR侧行链路传输，第一资源池包括NR侧行链路的传输资源。第二制式侧行链路传输为LTE侧行链路传输，第二资源池包括LTE侧行链路的传输资源。
第一资源池和第二资源池存在重叠，比如可以为上述图2中的(b)所示，第一资源池中的资源A 2与第二资源池中的资源B 2为第一资源池和第二资源池的重叠资源。且NR侧行链路传输对第一资源池中的资源占用较少。LTE侧行链路传输对第一资源池的资源A 2中的资源占用较多。
若网络设备不考虑LTE侧行链路对第一资源池的资源的占用程度，而是根据NR侧行链路传输对第一资源池的资源的占用程度为第一终端设备调度NR侧行链路的传输资源，若NR侧行链路传输对第一资源池中的资源占用较少，网络设备可能推断NR侧行链路的资源情况非常好(或者，网络设备可以推断此时的NR侧行链路传输大概率可以得到保障)。而又由于网络设备可以推断此时的NR侧行链路传输大概率可以得到保障，因此网络设备断定第一终端设备的通信性能是很容易满足，因此网络设备在为第一终端设备配置NR侧行链路传输参数时，会配置一些高要求的参数。
需要说明的是，本申请实施例中出现的网络设备或第一终端设备等装置为第一制式侧行链路配置传输参数，该配置的传输参数可以为层1的传输参数。也可以理解为网络设备可以根据NR侧行链路传输对第一资源池的资源的占用程度为NR侧行链路的传调整层1传输参数。
本申请实施例中，网络设备在具体配置参数时，可能会基于“第一终端设备的通信性能是很容易满足”这一条件进行参数配置，具体参数配置情况本申请实施例不做限制。为了更详细的介绍本申请实施例，下面给出一种可能的参数配置的几种示例，比如：子信道数量(sub-channel number)可以配置的多一些。再比如，重传次数(retransmission number)可以配置的少一些(因为数据传输成功率较高，因此重传数量可以配置的少一些)。再比如，编码和调制方案(modulation and coding scheme，MCS)可以配置的高阶。再比如，信道占用率(channel occupancy ratio，CR)限制(limit)可以设置的低一些。
值得说明的是，本申请实施例中网络设备可以基于更多的信息调度资源。而关于网络设备如何基于更多的信息调度资源，关于如何调整传输参数，本申请实施例不做限制。本申请实施例中给出的参数调整的方案仅仅是几种可能的示例，在具体实施中，网络设备可以自行根据实际情况进行参数配置，具体参数配置情况也有可能与本申请实施例给出的几种示例相同，也有可能不同，本申请实施例不做限制。
但是，若LTE侧行链路传输对第一资源池的资源A 2中的资源占用较多，LTE侧行链路的信道状态较差，或LTE侧行链路的资源情况较差。网络设备在为第一终端设备配置传输参数时若考虑了LTE侧行链路对第一资源池的影响，则网络设备可能断定第一终端设备的通信性能不容易满足，因此可能会为第一终端设备配置一些较低要求的参数，比如：子信道数量(sub-channel number)可以配置的少一些。再比如，重传次数(retransmission number)可以配置的多一些(因为数据传输成功率较低，因此重传数量可以配置的多一些)。再比如，MCS可以配置低阶。再比如，信道占用率(channel occupancy ratio，CR)限制(limit)可以设置偏高。
通过上述内容可以看出，若网络设备不考虑LTE侧行链路对第一资源池的资源的占用 程度，而是根据NR侧行链路传输对第一资源池的资源的占用程度为第一终端设备调度NR侧行链路的传输资源，则为NR侧行链路配置的传输参数可能会不合理，比如配置了要求偏高的一些传输参数，从而可能会导致无法保证第一终端设备的NR侧行链路的通信性能。
而本申请实施例中由于第一终端设备向网络设备发送第一指示信息，因此网络设备可以获取到更多的信息，进而网络设备在后续为NR侧行链路调度传输资源时，可以考虑NR侧行链路的资源使用情况，也考虑第一资源池上其他制式(比如LTE)的侧行链路的资源使用情况，进而可以更加合理的为NR侧行链路调度传输资源，可以更加合理的为NR侧行链路配置传输参数，进而可以减少NR侧行链路传输性能得不到保障的情况的发生。
需要说明的是，以上内容以网络设备为第一终端设备调度资源，且配置第一侧行链路的传输参数为例进行介绍，实际应用中，第一终端设备也可以基于第一资源池的资源和第二资源池的资源重叠的相关信息，从资源池中选择资源，以及确定第一侧行链路的传输参数，具体内容可以参见前述网络设备基于第一指示信息为第一终端设备的第一侧行链路调度资源以及配置传输参数的相关内容，不再赘述。
在上述步骤302中，第一指示信息可以是指至少能够指示出第一资源池的资源和第二资源池的资源重叠的信息，第一指示信息的具体形式有多种，比如可以包括以下示例a1、示例a2或示例a3中的至少一项。
示例a1，第一指示信息包括：指示第一资源池的资源和第二资源池的资源重叠的指示信息。
比如可以在第一消息中设置一个比特位，当该比特位的值为1，则表示第一资源池的资源和第二资源池的资源重叠，若该比特位的值为0，则表示第一资源池的资源和第二资源池的资源不重叠。
示例a2：第一指示信息包括：指示第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰的指示信息。
比如，可以在第一消息中设置一个比特位，当该比特位的值为1，则表示第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰，若该比特位的值为0，则表示第一资源池的资源未受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰。
一种可能的实施方式中，示例a2中，第一指示信息还可以包括指示第一资源池存在不同制式的内部无线接入技术(inter-radio access technology，inter-RAT))干扰情况的指示信息。一种可能的实施方式中，示例a2中，第一指示信息还可以包括指示第一资源池存在设备内共存(In-Device Coexistence，IDC)干扰情况的指示信息，第一指示信息还可以称为inter-RAT SL IDC指示信息，第一资源池存在IDC干扰情况，也可以理解为第一资源池收到受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰。
在示例a2中，由于第一指示信息能够指示出第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰，因此网络设备可以根据第一指示信息确定第一资源池的资源肯定和其他资源池的资源有重叠关系。在这里需要注意的是，步骤302中提到第一指示信息指示第一资源池的资源和第二资源池的资源重叠，第二资源池可以理解为与第一资源池不同的其他资源池，为了介绍方便，将其称为第二资源池。
示例a3：第一指示信息包括：指示第一资源池的资源受到第二制式侧行链路传输的干 扰的指示信息。
在实施例a3中，由于第一指示信息可以指示第一资源池的资源受到第二制式侧行链路传输的干扰，因此网络设备可以根据第一指示信息确定第一资源池的资源和第二制式侧行链路传输的对应的资源池(第二资源池)的资源重叠。
一种可能的实施方式中，在示例a3中，第一指示信息还可以指示出第二制式侧行链路传输的相关信息，比如第二制式侧行链路的标识信息等，以使网络设备可以根据第一指示信息确定对第一资源池的资源有干扰的侧行链路传输包括第二制式侧行链路传输。
通过上述内容可以看出，第一指示信息可以指示第一资源池的资源和第二资源池的资源重叠。当第一资源池的资源受到第二制式侧行链路传输干扰的情况下，第一指示信息可以是指示出第一资源池的资源和第二资源池的资源重叠的信息，也可以是指示出第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰的信息，或者也可以是指示第一资源池的资源受到第二制式侧行链路传输的干扰的信息。当第一资源池的资源受到第二制式侧行链路传输干扰，则第一资源池的资源和第二资源池的资源重叠。也就是说，当第一资源池的资源和第二资源池的资源重叠的时候，第一终端设备可以向网络设备上报第一指示信息，这种情况下，第一资源池的资源可能受到第二制式侧行链路传输干扰，也可能第一资源池未受到第二制式侧行链路传输干扰。
在上述步骤301之后，第一终端设备还可以向网络设备发送一些其他关于第一资源池和第二资源池的信息，比如第一终端设备还可以向网络设备发送以下的信息b1、信息b2、信息b3或信息b4中的一项或多项。信息b1、信息b2、信息b3或信息b4中的一项或多项可以承载于第一消息中一起发送至网络设备，也可以通过其他一条或多条消息发送至网络设备。信息b1、信息b2、信息b3或信息b4的具体发送方式，本申请实施例不做限制。
信息b1，第一资源池与第二资源池的重叠资源的时域信息和/或频域信息。
通过信息b1，网络设备可以确定出第一资源池和第二资源池中具体哪些资源重叠，进而在为第一终端设备调度第一资源池的资源时可以更加合理的调度。比如，第一资源池支持NR侧行链路传输，第二资源池支持LTE侧行链路传输，若LTE侧行链路对第一资源池和第二资源池的重叠资源占用较多，则网络设备可以尽量为第一终端设备的NR侧行链路调度第一资源池中除该重叠资源之外的资源，从而可以尽量避免为第一终端设备调度的NR侧行链路的资源与LTE侧行链路所占用的资源发生冲突的问题。
信息b2，第一资源池与第二资源池的重叠资源在第一资源池中的占比。
通过信息b2，网络设备可以获知更多第一资源池的信息，进而可以更加合理的为第一终端设备调度第一资源池的资源。
举个例子，第一资源池支持NR侧行链路传输，第二资源池支持LTE侧行链路传输。若网络设备确定第一资源池和第二资源池的重叠资源在第一资源池中的占比较小，则网络设备在为第一终端设备配置NR侧行链路传输参数时可以更多的考虑NR侧行链路传输对第一资源池的影响程度。也可以理解为NR侧行链路传输对第一资源池的影响程度这一因素对确定NR侧行链路传输参数的重要性可以偏大，LTE侧行链路传输对第一资源池的影响程度这一因素对确定NR侧行链路传输参数的重要性可以偏小。如此可以看出，基于信息b2为第一终端设备的NR侧行链路配置传输参数，可以提高配置的传输参数的合理性。
若网络设备确定第一资源池和第二资源池的重叠资源在第一资源池中的占比较大，则 网络设备在为第一终端设备配置NR侧行链路传输参数时不仅需要多考虑NR侧行链路传输对第一资源池的影响程度，也需要多考虑LTE侧行链路传输对第一资源池的影响程度。也可以理解为NR侧行链路传输对第一资源池的影响程度这一因素对确定NR侧行链路传输参数的重要性可以偏大，LTE侧行链路传输对第一资源池的影响程度这一因素对确定NR侧行链路传输参数的重要性也偏大。如此可以看出，基于信息b2为第一终端设备的NR侧行链路配置传输参数，可以提高配置的传输参数的合理性。
信息b3，指示第一资源池与第二资源池的重叠资源在第一资源池中占比是否为百分之百的指示信息。
一种可能的实施方式中，可以在第一消息中设置一个比特位，该比特位置1时，可以指示第一资源池与第二资源池的重叠资源在第一资源池中占比为百分之百，或者说，第二资源池的部分资源或全部资源与第一资源池的全部资源重叠。当该比特位置0，则可以指示第一资源池与第二资源池的重叠资源在第一资源池中占比并非百分之百。
当第一资源池与第二资源池的重叠资源在第一资源池中占比为百分之百，网络设备在为第一终端设备配置NR侧行链路传输参数时，NR侧行链路传输对第一资源池的影响程度这一因素对确定NR侧行链路传输参数的重要性可以偏大，LTE侧行链路传输对第一资源池的影响程度这一因素对确定NR侧行链路传输参数的重要性可以也偏大。如此可以看出，基于信息b3为第一终端设备的NR侧行链路配置传输参数，可以提高配置的传输参数的合理性。
当第一资源池与第二资源池的重叠资源在第一资源池中占比并非百分之百，网络设备在为第一终端设备配置NR侧行链路传输参数时，NR侧行链路传输对第一资源池的影响程度这一因素对确定NR侧行链路传输参数的重要性可以偏大，LTE侧行链路传输对第一资源池的影响程度这一因素对确定NR侧行链路传输参数的重要性可以偏小。如此可以看出，基于信息b3为第一终端设备的NR侧行链路配置传输参数，可以提高配置的传输参数的合理性。
信息b4，第一资源池的标识指示信息。
网络设备获取信息b4，则可以根据第一资源池的标识指示信息确定出第一资源池，进而可以至少确定出具体哪一个资源池的资源与其他资源池的资源重叠。
第一资源池的标识指示信息包括以下内容中的至少一项：第一资源池的标识；第一资源池的载波信息；或，第一资源池的BWP信息。
比如，当资源池的标识具有全局唯一性，根据资源池的标识可以唯一确定出一个资源池，则第一资源池的标识信息可以包括第一资源池的标识(identifier，ID)。
再比如，当资源池的标识在一个载波内具有唯一性，即在一个载波中一个资源池的标识可以唯一确定出一个资源池，则第一资源池的标识信息可以包括第一资源池的载波信息和第一资源池的标识(identifier，ID)。第一资源池的载波信息也可以称为载波标识。
再比如，当资源池的标识在一个带宽部分(bandwidth part，BWP)内具有唯一性，即在一个BWP中一个资源池的标识可以唯一确定出一个资源池，则第一资源池的标识信息可以包括第一资源池的载波信息、第一资源池的BWP信息和第一资源池的标识(identifier，ID)。第一资源池的BWP信息也可以称为BWP标识。
基于图3所示的内容，图4示例性示出本申请实施例提供的又一种通信方法的流程示 意图，如图4所示，该方法在步骤301之前还可以包括步骤401：
步骤401，网络设备发送第五消息，第五消息包括第一配置信息，第一配置信息指示：允许发送第一指示信息的指示信息。
相对应的，第一终端设备接收第五消息。
一种可能的实施方式中，也可以理解为第一配置信息用于指示：允许第一终端设备发送用于指示多个资源池的资源重叠的信息。又一种可能的实施方式中，也可以理解为第一配置信息用于指示：允许第一终端设备发送用于指示资源池受到多种不同制式的侧行链路的传输的干扰的信息。
本申请实施例中第五消息可以是一条新定义的消息，也可以是现有标准中定义的消息。当第五消息为现有标准中定义的消息，可以复用该消息中的比特位承载第一配置信息。
通过图4的方案可以看出，网络设备可以通过是否发送第一配置信息的方式指示是否允许(或者是否需要)第一终端设备发送用于指示多个资源池的资源重叠的信息。网络设备向第一终端设备发送第一配置信息，第一终端设备可以在确定第一资源池的资源和第二资源池的资源重叠的情况下发送第一指示信息。如此，可以使得第一终端设备需在网络设备允许其发送第一指示信息的情况下才可以发送第一指示信息，从而可以提高网络设备可以对第一终端设备的可管控程度，增大网络设备可以对第一终端设备进行管控的范围。
进一步，也可以使网络设备根据自身的能力灵活选择是否需要第一终端设备上报更多的信息，比如网络设备能力较强，则可以允许第一终端设备上报用于指示多个资源池的资源重叠的信息，如此网络设备可以基于接收到的信息更加合理的为第一终端设备配置传输参数。再比如，若网络设备能力较弱，则可以不发送第一配置信息，如此网络设备在为第一终端设备配置传输参数时考虑的因素较少，从而可以减少为第一终端设备配置传输参数时的复杂度。
又一种可能的实施方式中，当网络设备发送不允许发送用于指示多个资源池的资源重叠的指示信息，则第一终端设备即使确定第一资源池的资源和第二资源池的资源重叠，也不可以向网络设备发送第一指示信息。如此，可以减少第一终端设备与网络设备之间信令交互的数量，从而减轻网络负荷。
又一种可能的实施方式中，当第一终端设备未收到第一配置信息，第一终端设备在确定第一资源池的资源和第二资源池的资源重叠的情况下，也可以不发送第一指示信息。如此，可以使得第一终端设备需在网络设备允许其发送第一指示信息的情况下才可以发送第一指示信息，从而可以提高网络设备可以对第一终端设备的可管控程度，增大网络设备可以对第一终端设备进行管控的范围。
基于上述内容，图5示例性示出本申请实施例提供的又一种通信方法的流程示意图，如图5所示，该方法包括：
步骤501，网络设备发送第六消息，第六消息包括第二配置信息，第二配置信息包括第一忙碌率阈值和/或第二忙碌率阈值。
其中，第一忙碌率阈值指示发送第一消息的触发事件包括触发事件c1。其中，触发事件c1：第一信道忙碌率大于第一忙碌率阈值。
第二忙碌率阈值指示发送第一消息的触发事件包括触发事件c2。其中，触发事件c2：第一信道忙碌率小于第二忙碌率阈值。
本申请实施例中第一忙碌率阈值与第二忙碌率阈值不同。一种可能的实施方式中，第一忙碌率阈值可以大于第二忙碌率阈值。
一种可能的实施方式中，第六消息还可以携带第一配置信息，也可以不携带第一配置信息，第一配置信息指示：允许发送第一指示信息的指示信息。当第六消息携带第一配置信息，第二配置信息和第一配置信息可以为两个不同的信息，又一种可能的实施方式中，第二配置信息可以作为第一配置信息的一种可能的实施方式，比如第二配置信息与第一配置信息可以为同一个信息，再比如第二配置信息可以包括第一配置信息。比如，当第一终端设备从网络设备接收到第二配置信息，则可以确定网络设备允许第一终端设备发送第一指示信息。
本申请实施例中第六消息可以是一条新定义的消息，也可以是现有标准中定义的消息。当第六消息为现有标准中定义的消息，可以复用该消息中的比特位承载第二配置信息。
又一种可能的实施方式中，图5所示的方案可以与图4所示的方案结合使用，在步骤504之前还可以包括步骤401，这种情况下，第六消息中不携带第一配置信息。
步骤502，第一终端设备确定第一信道忙碌率。
第一信道忙碌率指示第二制式侧行链路传输对第一资源池的资源的影响程度。
本申请实施例中的第一信道忙碌率属于信道忙碌率(channel busy ratio，CBR)中的一种可能的实施方式，为了容易区分，本申请实施例中将其称为第一信道忙碌率。本申请实施例中的第一信道忙碌率可以为一个0至100的整数，可以分别对应0-1的比例范围。
示例性的，本申请实施例中第一信道忙碌率还可以有其他的名称，比如，当第一制式侧行链路传输为NR侧行链路传输，第一信道忙碌率还可以称为NR SL CBR等名称，本申请实施例不做限制。
第一信道忙碌率的计算方式有多种，下面通过以下方式d1、方式d2和方式d3进行介绍。
方式d1：第一信道忙碌率根据第一目标子信道在第一资源池的子信道的占比确定。
本申请实施例中，第一目标子信道包括第一资源池和第二资源池的重叠资源中第二制式侧行链路传输对应的接收信号强度大于第一信号强度阈值的子信道。本申请实施例中接收信号强度可以为接收信号强度指示(received signal strength indicator，RSSI)。
比如，第一终端设备(比如处于RRC_连接态、RRC_非激活态或RRC_空闲态的第一终端设备)可以对第二侧行链路对应的接收信号强度进行测量，从而确定出第一目标子信道的数量。以上述图2中的(d)为例，第一终端设备可以将第一资源池的资源A 2中的第二制式侧行链路传输对应的接收信号强度大于第一信号强度阈值的子信道确定为第一目标子信道，并确定出第一目标子信道的数量。进而第一终端设备根据第一目标子信道的数量在第一资源池的子信道的占比确定第一信道忙碌率。
通过方式d1计算出的第一信道忙碌率可以反映出第二制式侧行链路传输对整个第一资源池的资源的影响程度，如此，当网络设备接收到第一指示信息，则说明第二制式侧行链路传输对整个第一资源池的资源的影响程度较大或较小(满足第一触发事件组中的至少一个事件)，进而网络设备可以更加合理的对第一资源池中的资源进行调度，也可以为第一终端设备配置更加合理的第一侧行链路传输参数。又一种可能的实施方式中，当网络设备接收到该第一信道忙碌率，由于第一信道忙碌率指示第二制式侧行链路传输对整个第一 资源池的资源的影响程度，因此网络设备可以根据第一信道忙碌率更加合理的对第一资源池中的资源进行调度，也可以为第一终端设备配置更加合理的第一侧行链路传输参数。
方式d2：第一信道忙碌率根据第一目标子信道在第一资源池与第二资源池的重叠资源的子信道的占比确定。
以上述图2中的(d)为例，第一终端设备可以将第一资源池的资源A 2中的第二制式侧行链路传输对应的接收信号强度大于第一信号强度阈值的子信道确定为第一目标子信道，并确定出第一目标子信道的数量。进而第一终端设备根据第一目标子信道的数量在第一资源池的资源A 2的子信道中的占比确定第一信道忙碌率。
通过方式d2计算出的第二信道忙碌率可以反映出第二制式侧行链路传输对第一资源池与第二资源池的重叠资源的影响程度，如此，网络设备可以更加合理的调度第一资源池与第二资源池的重叠资源。且在为第一终端设备调度第一资源池与第二资源池的重叠资源时，可以更加合理的配置传输参数。
通过方式d2计算出的第一信道忙碌率可以反映出第二制式侧行链路传输对第一资源池与第二资源池的重叠资源的影响程度，如此，当网络设备接收到第一指示信息，则说明第二制式侧行链路传输对第一资源池与第二资源池的重叠资源的影响程度较大或较小(满足第一触发事件组)，进而网络设备可以更加合理的对第一资源池与第二资源池的重叠资源中的资源进行调度，也可以为第一终端设备配置更加合理的第一侧行链路传输参数。又一种可能的实施方式中，当网络设备接收到该第一信道忙碌率，由于第一信道忙碌率指示第二制式侧行链路传输对第一资源池与第二资源池的重叠资源的影响程度，因此网络设备可以根据第一信道忙碌率更加合理的对第一资源池与第二资源池的重叠资源进行调度，也可以为第一终端设备配置更加合理的第一侧行链路传输参数。
方式d3：第一信道忙碌率根据第四信道忙碌率确定。
第四信道忙碌率指示第二制式侧行链路传输对第二资源池的资源的影响程度。
第四信道忙碌率根据第二资源池中第二制式侧行链路传输对应的接收信号强度大于第五信号强度阈值的子信道在第二资源池的子信道中的占比。以上述图2中的(d)为例，第一终端设备可以将第二资源池中的第二制式侧行链路传输对应的接收信号强度大于第五信号强度阈值的子信道在第二资源池的子信道中的占比确定为第四信道忙碌率。
一种可能的实施方式中，可以将第四信道忙碌率确定为第一信道忙碌率。这种情况下，可以认为第二资源池中的资源被均匀的占用，因此将第四信道忙碌率近似视为第一信道忙碌率，即将第二制式侧行链路传输对第二资源池的资源的影响程度近似视为：第二制式侧行链路传输对第一资源池的资源的影响程度。
如此，可以多提供一种确定第一信道忙碌率的方法，从而在第一终端设备无法得到较为准确的第一信道忙碌率的情况下，也可以基于第四信道忙碌率确定第二制式侧行链路传输对第一资源池的资源的影响程度，继而可以降低对第一终端设备能力的要求，可以增加本申请实施例的适用场景。
步骤503，第一终端设备确定第一信道忙碌率满足第一触发事件组中的至少一个触发事件。
其中，第一触发事件组可以包括一个或多个触发事件，比如第一触发事件组可以包括触发事件c1和/或触发事件c2。
一种可能的实施方式中，第一触发事件组中的触发事件可以是根据第二配置信息确定。比如若第二配置信息包括第一忙碌率阈值，则第一触发事件组可以包括触发事件c1。再比如若第二配置信息包括第二忙碌率阈值，则第一触发事件组可以包括触发事件c2。再比如若第二配置信息包括第一忙碌率阈值和第二忙碌率阈值，则第一触发事件组可以包括触发事件c1和触发事件c2。
又一种可能的实施方式中，第一触发事件组中的事件可以是预先设置在第一终端设备侧的，步骤501可以不执行，也可以执行。当第一终端设备侧预设第一触发事件组，而网络设备执行步骤501的情况下，第一终端设备可以将步骤501中第二配置信息指示的触发事件更新为第一触发事件组中的事件。比如，第一终端设备侧预设第一忙碌率阈值，网络设备下发了新的第一忙碌率阈值，则第一终端设备可以根据网络设备下发的新的第一忙碌率阈值执行判断第一信道忙碌率是否满足触发事件c1。
本申请实施例中步骤503为可选择的步骤，并不是必须执行的步骤。
步骤502可以为步骤301的一种可能的实施方式，步骤502和步骤503可以为步骤301的又一种可能的实施方式。比如，当第一终端设备能够计算出第一信道忙碌率(第一信道忙碌率不为0)，则说明第一资源池上可能有第二制式侧行链路传输，则说明第一资源池的资源和第二资源池的资源可能重叠。再比如，当第一终端设备确定第一信道忙碌率满足第一触发事件组中的至少一个事件，则说明第一资源池上有第二制式侧行链路传输，则说明第一资源池的资源和第二资源池的资源重叠。
步骤504，第一终端设备发送第一消息。
相对应的，网络设备接收第一消息。
第一消息中可以包括第一信道忙碌率，也可以不包括第一信道忙碌率。当第一消息中包括第一信道忙碌率的情况下，本申请实施例中第一消息中的第一信道忙碌率和第一指示信息可以为两个信息。
又一种可能的实施方式中，第一信道忙碌率可以作为第一指示信息的一种可能的实现方式，比如第一指示信息可以包括第一信道忙碌率，再比如第一指示信息可以为第一信道忙碌率，这种情况下，也可以理解为第一消息中包括第一信道忙碌率，不包括第一指示信息。网络设备基于第一信道忙碌率可以确定第一资源池的资源和第二资源池的资源重叠。
又一种可能的实施方式中，第一终端设备也可以通过多条消息分别向网络设备发送第一指示信息和第一信道忙碌率。
本申请实施例中，第一终端设备至少根据第一信道忙碌率发送第一消息。一种可能的实施方式中，第一终端设备至少根据第一信道忙碌率发送第一消息，包括：第一终端设备在第一消息中携带第一信道忙碌率，并发送第一消息。这种情况下，图5所示的方案中，步骤501和步骤503可以执行，也可以不执行。
又一种可能的实施方式中，第一终端设备至少根据第一信道忙碌率发送第一消息，包括：第一终端设备发送第一消息之前需要确定第一信道忙碌率满足第一触发事件组中的至少一个事件。又一种可能的实施方式中，当第一终端设备确定第一信道忙碌率不满足第一 触发事件组中的全部事件中的每个事件，则第一终端设备可以不发送第一消息。
通过图5所示的方案可以看出，第一终端设备至少根据第一信道忙碌率发送第一消息，比如，第一终端设备可以在第一信道忙碌率满足一定的条件的情况下才发送第一消息，如此，可以减少网络设备接收到的信息的数量，节省信令传输所消耗的资源。再比如，第一终端设备可以向网络设备发送第一信道忙碌率，如此，网络设备可以根据第一信道忙碌率确定第二制式侧行链路传输对第一资源池的资源的影响程度。比如，当第二制式侧行链路传输对第一资源池的资源的影响程度较大的情况，在为第一终端设备的第一制式侧行链路传输配置传输参数时，可以将第二制式侧行链路传输对第一资源池的影响程度这一因素的重要性提高。再比如，当第二制式侧行链路传输对第一资源池的资源的影响程度较小的情况，在为第一终端设备的第一制式侧行链路传输配置传输参数时，可以将第二制式侧行链路传输对第一资源池的影响程度这一因素的重要性降低。如此，网络设备可以为第一终端设备的第一制式侧行链路传输配置更合理的传输参数。
基于上述内容，图6示例性示出本申请实施例提供的又一种通信方法的流程示意图，如图6所示，该方法包括：
步骤601，网络设备发送第七消息。
本申请实施例中第七消息可以是一条新定义的消息，也可以是现有标准中定义的消息。
一种可能的实施方式中，第七消息可以为网络设备向第一终端设备发送的侧行链路信道忙碌率测量请求消息，第七消息用于请求第一终端设备测量第一资源池的信道忙碌率。
又一种可能的实施方式中，第七消息中还可以包括：请求第一终端设备测量第二信道忙碌率的资源池的信息，比如第七消息中可以包括第一资源池的配置信息和/或第一资源池的标识指示信息等。
又一种可能的实施方式中，第七消息包括第三配置信息，第三配置信息包括第三忙碌率阈值和/或第四忙碌率阈值。
其中，第三忙碌率阈值指示发送第一消息的触发事件包括触发事件e1。其中，触发事件e1：第二信道忙碌率大于第三忙碌率阈值。
第四忙碌率阈值指示发送第一消息的触发事件包括触发事件e2。其中，触发事件e2：第二信道忙碌率小于第四忙碌率阈值。
又一种可能的实施方式中，第七消息还可以携带第一配置信息，也可以不携带第一配置信息，第一配置信息指示：允许发送第一指示信息的指示信息。又一种可能的实施方式中，图6所示的方案可以与图4所示的方案结合使用，在步骤606之前还可以包括步骤401，这种情况下，第七消息中不携带第一配置信息。
本申请实施例中，第三忙碌率阈值与第四忙碌率阈值不同。一种可能的实施方式中，第三忙碌率阈值可以大于第四忙碌率阈值。第三忙碌率阈值可以与第一忙碌率阈值或第二忙碌率阈值相同；或者，第三忙碌率阈值与第一忙碌率阈值不同，且第三忙碌率阈值与第二忙碌率阈值不同。第四忙碌率阈值可以与第一忙碌率阈值或第二忙碌率阈值相同；或者， 第四忙碌率阈值与第一忙碌率阈值不同，第四忙碌率阈值与第二忙碌率阈值不同。
步骤602，第一终端设备确定第二信道忙碌率。
第二信道忙碌率指示第一制式侧行链路传输对第一资源池的资源的影响程度。
本申请实施例中的第二信道忙碌率可以为一个0至100的整数，可以分别对应0-1的比例范围。
一种可能的实施方式中，第二信道忙碌率根据第二目标子信道在第一资源池的子信道中的占比确定。第二目标子信道包括第一资源池中第一制式侧行链路传输对应的接收信号强度大于第二信号强度阈值的子信道。
比如，第一终端设备(比如处于RRC_连接态、RRC_非激活态或RRC_空闲态的第一终端设备)可以对第一侧行链路对应的接收信号强度进行测量，从而确定出第二目标子信道的数量。进而第一终端设备根据第二目标子信道的数量在第一资源池的子信道的占比确定第二信道忙碌率。
步骤603，第一终端设备确定第二信道忙碌率满足第二触发事件组中的至少一个触发事件。
其中，第二触发事件组可以包括一个或多个触发事件，比如第二触发事件组可以包括触发事件e1和/或触发事件e2。
一种可能的实施方式中，第二触发事件组中的触发事件可以是根据第三配置信息确定。比如若第三配置信息包括第三忙碌率阈值，则第二触发事件组可以包括触发事件e1。再比如若第三配置信息包括第四忙碌率阈值，则第二触发事件组可以包括触发事件e2。再比如若第三配置信息包括第三忙碌率阈值和第四忙碌率阈值，则第二触发事件组可以包括触发事件e1和触发事件e2。
又一种可能的实施方式中，第二触发事件组中的事件可以是预先设置在第一终端设备侧的。当第一终端设备侧预设第二触发事件组，而网络设备下发第三配置信息的情况下，第一终端设备可以将第三配置信息指示的触发事件更新为第二触发事件组中的事件。比如，第一终端设备侧预设第三忙碌率阈值，网络设备下发了新的第三忙碌率阈值，则第一终端设备可以根据网络设备下发的新的第三忙碌率阈值执行判断第二信道忙碌率是否满足触发事件e1。
本申请实施例中步骤603为可选择的步骤，并不是必须执行的步骤。
一种可能的实施方式中，在步骤606之前还可以执行步骤604。又一种可能的实施方式中，在步骤606之前还可以执行步骤604和步骤605。步骤604可以为步骤301的一种可能的实施方式。步骤604和步骤605可以为步骤301的又一种可能的实施方式。步骤605为可选的步骤。如图6所示，在步骤606之前，还包括：
步骤604，第一终端设备确定第一信道忙碌率。
步骤604的相关内容可以参见前述步骤502的相关内容，在此不再赘述。
步骤605，第一终端设备确定第一信道忙碌率满足第一触发事件组中的至少一个触发事件。
本申请实施例中步骤605为可选择的步骤，并不是必须执行的步骤。步骤605的相关内容可以参见前述步骤503的相关内容，在此不再赘述。
值得注意的是，步骤604与步骤601和步骤602中的任一项没有必然的先后关系，步骤605与步骤601和步骤602中的任一项没有必然的先后关系，图6中以步骤604和步骤605在步骤602之后执行为例进行示意。
进一步，由于图6所示的方案还执行步骤604和步骤605，因此，一种可能的实施方式中，第七消息中还可以包括第二配置信息，第二配置信息包括第一忙碌率阈值和/或第二忙碌率阈值。第二配置信息的相关内容参考前述描述，在此不再赘述。
步骤606，第一终端设备发送第一消息。
相对应的，网络设备接收第一消息。
第一消息中可以包括第二信道忙碌率。
本申请实施例中第一消息中还可以包括其他信息，比如第一消息可以包括第一指示信息。再比如第一消息可以包括信息b1、信息b2、信息b3或信息b4中的一项或多项等，相关内容可以参见前述描述，此处不再赘述。
又一种可能的实施方式中，由于在图6中可能执行步骤604和步骤605，因此，第一消息中还可以包括第一信道忙碌率。可选地，第一消息也可以不包括第一信道忙碌率。第一信道忙碌率与第一指示信息的关系参考前述图5的相关描述，在此不再赘述。
本申请实施例中，第一终端设备至少根据第二信道忙碌率发送第一消息。一种可能的实施方式中，第一终端设备至少根据第二信道忙碌率发送第一消息，包括：第一终端设备在第一消息中携带第二信道忙碌率，并发送第一消息。这种情况下，图5所示的方案中，步骤601和步骤603可以执行，也可以不执行。
又一种可能的实施方式中，第一终端设备至少根据第二信道忙碌率发送第一消息，包括：第一终端设备发送第一消息之前需要确定第二信道忙碌率满足第二触发事件组中的至少一个事件。又一种可能的实施方式中，当第一终端设备确定第二信道忙碌率不满足第二触发事件组中的全部事件中的每个事件，则第一终端设备可以不发送第一消息。
通过图6所示的方案可以看出，当网络设备请求第一终端设备测量第一资源池的信道忙碌率(称为第二信道忙碌率)的情况下，第一终端设备还可以上报能够指示出第一资源池的资源和第二资源池的资源重叠的指示信息，比如第一终端设备除了向网络设备上报第二信道忙碌率之外，还可以向网络设备上报第一信道忙碌率，以使网络设备不仅可以确定第一制式侧行链路传输对第一资源池的资源的影响程度，还可以确定出第二制式侧行链路传输对第一资源池的资源的影响程度，进而可以更好的为第一终端设备的第一制式侧行链路传输调度资源。
进一步，图6所示的方案中，步骤601可以为现有标准中的用于请求第一终端设备测量第一资源池的信道忙碌率的消息，继而第一终端设备在基于该请求消息向网络设备上报第一资源池的信道忙碌率(即第二信道忙碌率)时，也可以将指示出第一资源池的资源和第二资源池的资源重叠的指示信息(比如第一信道忙碌率等)上报至网络设备，可以看出，该流程在现有的标准流程的基础上进行了改进，从而可以更好的与现有标准兼容。
基于上述内容，图7示例性示出本申请实施例提供的又一种通信方法的流程示意图，如图7所示，该方法包括：
步骤701，网络设备发送第八消息。
本申请实施例中第八消息可以是一条新定义的消息，也可以是现有标准中定义的消息。
一种可能的实施方式中，第八消息可以为网络设备向第一终端设备发送的侧行链路信道忙碌率测量请求消息，第八消息用于请求第一终端设备测量第一资源池的信道忙碌率。
又一种可能的实施方式中，第八消息中还可以包括：请求第一终端设备测量第二信道忙碌率的资源池的信息，比如第八消息中可以包括第一资源池的配置信息和/或第一资源池的标识指示信息等。
又一种可能的实施方式中，第八消息包括第四配置信息，第四配置信息包括第五忙碌率阈值和/或第六忙碌率阈值。
其中，第五忙碌率阈值指示发送第一消息的触发事件包括触发事件f1。其中，触发事件f1：第三信道忙碌率大于第五忙碌率阈值。
第六忙碌率阈值指示发送第一消息的触发事件包括触发事件f2。其中，触发事件f2：第三信道忙碌率小于第六忙碌率阈值。
本申请实施例中，第五忙碌率阈值与第六忙碌率阈值不同。一种可能的实施方式中，第五忙碌率阈值可以大于第六忙碌率阈值。第五忙碌率阈值可以与第一忙碌率阈值、第二忙碌率阈值、第三忙碌率阈值或第四忙碌率阈值相同；或者，第一忙碌率阈值与第一忙碌率阈值、第二忙碌率阈值、第三忙碌率阈值和第四忙碌率阈值中的每一项均不同。第六忙碌率阈值可以与第一忙碌率阈值、第二忙碌率阈值、第三忙碌率阈值或第四忙碌率阈值相同；或者，第六忙碌率阈值与第一忙碌率阈值、第二忙碌率阈值、第三忙碌率阈值和第四忙碌率阈值中的每一项均不同。
本申请实施例中，第二配置信息、第三配置信息、第四配置信息或第一配置信息中的任意两个配置信息可以为同一个配置信息，也可以为不同的配置信息。或者，也可以理解为：第二配置信息、第三配置信息、第四配置信息或第一配置信息中的任意两个配置信息：可以为承载于同一个消息中的同一个配置信息中的同一个信息，也可以为承载于同一个消息中的同一个配置信息中的两个信息，也可以为承载于不同的消息中的两个不同的配置信息。
又一种可能的实施方式中，第八消息可以包括第一配置信息。第一配置信息指示：允许发送第一指示信息的指示信息。第一配置信息的相关内容可以参见前述描述，在此不再赘述。又一种可能的实施方式中，图7所示的方案可以与图4所示的方案结合使用，在步骤704之前还可以包括步骤401，这种情况下，第八消息中不携带第一配置信息。
步骤702，第一终端设备确定第三信道忙碌率。
第三信道忙碌率指示第一制式侧行链路传输以及第二制式侧行链路传输对第一资源池的资源的影响程度。
本申请实施例中的第三信道忙碌率可以为一个0至100的整数，可以分别对应0-1的比例范围。
示例性的，本申请实施例中第三信道忙碌率还可以有其他的名称，比如可以为内部无线接入技术侧行链路信道忙碌率(inter-RAT SL CBR)等名称，本申请实施例不做限制。
本申请实施例中的第三信道忙碌率可以为一个0至100的整数，可以分别对应0-1的比例范围。
一种可能的实施方式中，第三信道忙碌率根据第一资源池中第一制式侧行链路传输对应的接收信号强度，以及第一资源池和第二资源池的重叠资源的第二制式侧行链路传输对应的接收信号强度确定。第三信道忙碌率的计算方式有多种，下面通过以下方式g1、方式g2和方式g3进行介绍。
方式g1：第一信道忙碌率和第二信道忙碌率的平均值。
由于第一信道忙碌率可以反映第二制式侧行链路传输对第一资源池的资源的影响程度，第二信道忙碌率可以反映第一制式侧行链路传输对第一资源池的资源的影响程度，因此可以通过对第一信道忙碌率和第二信道忙碌率的计算得到第三信道忙碌率。比如将第一信道忙碌率和第二信道忙碌率的平均值作为第三信道忙碌率，该方案可以降低第三信道忙碌率的计算复杂度。
方式g2：第一信道忙碌率和第二信道忙碌率的加权平均值。
第一信道忙碌率的权重根据第一资源池与第二资源池的重叠资源在第一资源池中的占比确定。
一种可能的实施方式中，第三信道忙碌率＝(第二信道忙碌率+a*第一信道忙碌率)/(1+a)；其中，a为第一信道忙碌率的权重，a可以为第一资源池与第二资源池的重叠资源在第一资源池中的占比。
相比方式g1，方式g2中由于加入了第一资源池与第二资源池的重叠资源在第一资源池中的占比作为权重，因此得到的第三信道忙碌率可以更加准确的反映出第一制式侧行链路传输以及第二制式侧行链路传输对第一资源池的资源的影响程度。
方式g3：第三信道忙碌率包括第三目标子信道的数量在第一资源池的子信道中的占比。
其中，第三目标子信道包括第一资源池中满足以下内容中至少一项的子信道：
第一制式侧行链路传输对应的接收信号强度大于第三信号强度阈值；或，第二制式侧行链路传输对应的接收信号强度大于第四信号强度阈值。
比如，第一终端设备(比如处于RRC_连接态、RRC_非激活态或RRC_空闲态的第一终端设备)可以对第一资源池的子信道上的接收信号强度进行测量，针对第一资源池上的子信道，第一终端设备需要对子信道上的第一侧行链路对应的接收信号强度进行测量，也需要对该子信道上的第二侧行链路对应的接收信号强度进行测量，当该子信道的第一制式侧行链路传输对应的接收信号强度大于第三信号强度阈值；和/或，该子信道的第二制式侧行链路传输对应的接收信号强度大于第四信号强度阈值，则确定该子信道为第三目标子信道。进而第一终端设备根据第三目标子信道的数量在第一资源池的子信道的占比确定第三信道忙碌率。
本申请实施例中，第一信号强度阈值、第二信号强度阈值、第五信号强度阈值、第三信号强度阈值或第四信号强度阈值中的任意两项可以相同，也可以不同，本申请实施例不做限制。
通过方式g1计算出的第三信道忙碌率可以反映出第一制式侧行链路传输和第二制式侧行链路传输对整个第一资源池的资源的影响程度，如此，当网络设备接收到第一指示信息，则说明第一制式侧行链路传输和第二制式侧行链路传输对整个第一资源池的资源的影响程度较大或较小(满足第三触发事件组中的至少一个事件)，进而网络设备可以更加合理的对第一资源池中的资源进行调度。
相比方式g1和方式g2，方式g3中由于可以通过统计第三目标子信道的数量在第一资源的子信道中的占比确定第三信道忙碌率，因此得到的第三信道忙碌率可以更加准确的反映出第一制式侧行链路传输以及第二制式侧行链路传输对第一资源池的资源的影响程度。
步骤703，第一终端设备确定第三信道忙碌率满足第三触发事件组中的至少一个触发事件。
其中，第三触发事件组可以包括一个或多个触发事件，比如第三触发事件组可以包括触发事件f1和/或触发事件f2。
一种可能的实施方式中，第三触发事件组中的触发事件可以是根据第四配置信息确定。比如若第四配置信息包括第五忙碌率阈值，则第三触发事件组可以包括触发事件f1。再比如若第四配置信息包括第六忙碌率阈值，则第三触发事件组可以包括触发事件f2。再比如若第四配置信息包括第五忙碌率阈值和第六忙碌率阈值，则第三触发事件组可以包括触发事件f1和触发事件f2。
又一种可能的实施方式中，第三触发事件组中的事件可以是预先设置在第一终端设备侧的。当第一终端设备侧预设第三触发事件组，而网络设备下发第四配置信息的情况下，第一终端设备可以将第四配置信息指示的触发事件更新为第三触发事件组中的事件。比如，第一终端设备侧预设第五忙碌率阈值，网络设备下发了新的第五忙碌率阈值，则第一终端设备可以根据网络设备下发的新的第五忙碌率阈值执行判断第三信道忙碌率是否满足触发事件f1。
本申请实施例中步骤703为可选择的步骤，并不是必须执行的步骤。
一种可能的实施方式中，在步骤706之前还可以执行步骤704，或者执行步骤704和步骤705。如图7所示，在步骤706之前，还包括：
步骤704，第一终端设备确定第二信道忙碌率。
步骤704的相关内容可以参见前述步骤602的相关内容，在此不再赘述。
步骤705，第一终端设备确定第二信道忙碌率满足第二触发事件组中的至少一个触发事件。
本申请实施例中步骤703为可选择的步骤，并不是必须执行的步骤。步骤705的相关内容可以参见前述步骤603的相关内容，在此不再赘述。
值得注意的是，步骤704与步骤701和步骤702中的任一项没有必然的先后关系，步骤705与步骤701和步骤702中的任一项没有必然的先后关系，图7中以步骤704和步骤705在步骤702之后执行为例进行示意。
进一步，由于图7所示的方案还执行步骤704和步骤705，因此，一种可能的实施方式中，第八消息中还可以包括第二配置信息，第二配置信息包括第三忙碌率阈值和/或第四 忙碌率阈值。第二配置信息的相关内容参考前述描述，在此不再赘述。
步骤706，第一终端设备发送第一消息。
相对应的，网络设备接收第一消息。
第一消息中可以包括第三信道忙碌率，也可以不包括第三信道忙碌率。当第一消息中包括第三信道忙碌率的情况下，本申请实施例中第一消息中的第三信道忙碌率和第一指示信息可以为两个信息。又一种可能的实施方式中，第三信道忙碌率可以作为第一指示信息的一种可能的实现方式，比如第一指示信息可以包括第三信道忙碌率，再比如第一指示信息可以为第三信道忙碌率。网络设备基于第三信道忙碌率可以确定第一资源池的资源和第二资源池的资源重叠。
又一种可能的实施方式中，第一终端设备也可以通过多条消息分别向网络设备发送第一指示信息和第三信道忙碌率。
当图7的方案中执行步骤704，又一种可能的实施方式中，第一消息中可以包括第二信道忙碌率，也可以不包括第二信道忙碌率。
本申请实施例中，第一消息中还可以包括其他信息，比如第一消息可以信息b1、信息b2、信息b3或信息b4中的一项或多项等，相关内容可以参见前述描述，此处不再赘述。
本申请实施例中，第一终端设备至少根据第三信道忙碌率发送第一消息。一种可能的实施方式中，第一终端设备至少根据第三信道忙碌率发送第一消息，包括：第一终端设备在第一消息中携带第三信道忙碌率，并发送第一消息。
又一种可能的实施方式中，第一终端设备至少根据第三信道忙碌率发送第一消息，包括：第一终端设备发送第一消息之前需要确定第三信道忙碌率满足第三触发事件组中的至少一个事件。又一种可能的实施方式中，当第一终端设备确定第三信道忙碌率不满足第三触发事件组中的全部事件中的每个事件，则第一终端设备可以不发送第一消息。
又一种可能的实施方式中，图7所示的方案中在步骤706之前第一终端设备还可以执行前述步骤502和步骤503，或者还可以执行步骤502，进一步，第一消息中还可以包括第一信道忙碌率。可选地，第一消息也可以不包括第一信道忙碌率。一种可能的实施方式中，第一信道忙碌率可以作为第一指示信息的一种可能的实现方式，比如第一指示信息可以包括第一信道忙碌率和第三信道忙碌率，再比如第一指示信息可以为第一信道忙碌率和第三信道忙碌率。第一信道忙碌率的其他内容可以参见前述图5的相关描述，在此不再赘述。
通过图7所示的方案可以看出，第一终端设备可以至少根据第三信道忙碌率发送第一消息，比如，第一终端设备可以在第三信道忙碌率满足一定的条件的情况下才发送第一消息，如此，可以减少网络设备接收到的信息的数量，节省信令传输所消耗的资源。再比如，第一终端设备可以向网络设备发送第三信道忙碌率，如此，网络设备可以根据第三信道忙碌率确定第一制式侧行链路传输和第二制式侧行链路传输对第一资源池的资源的影响程度。相比仅仅根据第一制式侧行链路传输对第一资源池的资源的影响程度为第一制式侧行链路传输调度资源，图7的方案中可以更加合理的对第一制式侧行链路传输进行资源调度， 进而可以提高第一制式侧行链路传输的通信性能得以保障的可能性。
进一步，图7所示的方案中，步骤701可以为现有标准中的用于请求第一终端设备测量第一资源池的信道忙碌率的消息，第一终端设备可以基于该请求消息向网络设备上报第三信道忙碌率，而不再上报第二信道忙碌率，可以看出，该流程在现有的标准流程的基础上进行了改进，从而可以更好的与现有标准兼容。且该改动较小，可有利于该方案的推广。
另外，需要注意的是，本申请实施例中通过步骤706上报第一消息之后，网络设备可以在通过步骤706之后确定第一资源池的资源和第二资源池的资源重叠。进一步，网络设备可以根据接收到的第一消息获知更多的信息，进而可以根据该获知的更多的信息调度资源或为第一制式侧行链路配置传输参数。相关内容可以参见前述描述，在此不再赘述。
基于上述内容，图8示例性示出本申请实施例提供的又一种通信方法的流程示意图。
图8所示的方案可以由两个不同的终端设备执行，比如可以由第一终端设备和第二终端设备执行。本申请实施例中第一终端设备侧执行的方案还可以由第一终端设备内部的单元、模块或芯片执行。本申请实施例中第二终端设备侧执行的方案还可以由第二终端设备内部的单元、模块或芯片执行。该场景中，第一终端设备可以为支持第一制式侧行链路传输，不支持第二制式侧行链路传输的终端设备，比如第一终端设备包括第一制式侧行链路传输通信模块，不包括第二制式侧行链路传输通信模块。第二终端设备可以为支持第二制式侧行链路传输，不支持第一制式侧行链路传输的终端设备，比如第二终端设备包括第二制式侧行链路传输通信模块，不包括第一制式侧行链路传输通信模块。
图8所示的方案也可以由同一个终端设备的两个模块执行，比如可以由第一终端设备内部的两个模块执行，该两个模块可以分别称为第一制式侧行链路传输通信模块以及第二制式侧行链路传输通信模块。该场景下，第一终端设备可以为支持第一制式侧行链路传输，也支持第二制式侧行链路传输的终端设备。
图8中以执行主体为第一终端设备和第二终端设备为例进行展示，当执行主体为第一终端设备内部的两个模块时，该两个模块执行的方案与第一终端设备和第二终端设备执行的方案类似，第一终端设备执行的方法步骤由第一终端设备中的一个模块(比如第一制式侧行链路传输通信模块)执行，第二终端设备执行的方法步骤由第一终端设备内部的另一个模块(比如第二制式侧行链路传输通信模块)执行，不再赘述。
如图8所示，该方法包括：
步骤801，第一终端设备确定第二信道忙碌率。
步骤801的相关内容可以参见前述步骤602的相关描述，不再赘述。
步骤802，第一终端设备确定第二信道忙碌率满足第二触发事件组中的至少一个触发事件。
步骤802的相关内容可以参见前述步骤603的相关描述，不再赘述。
步骤802为可选地步骤。或者，步骤801和步骤802为可选的步骤。
步骤803，第一终端设备向第二终端设备发送第二消息，第二消息请求查询第一资源池的资源和第二资源池的资源是否重叠。
相对应的，第二终端设备接收第二消息。
一种可能的实施方式中，第二消息中可以携带第一资源池的信息，比如第一资源池的配置信息和/或第一资源池的标识信息，以便第二终端设备根据第二消息确定出第一资源池。
又一种可能的实施方式中，第二请求消息可以用于请求获取第一信道忙碌率。又一种可能的实施方式中，第二请求消息中可以包括第一忙碌率阈值和第二忙碌率阈值。
其中，第二请求消息中携带的第一忙碌率阈值指示发送第三消息的触发事件包括触发事件c1。其中，触发事件c1：第一信道忙碌率大于第一忙碌率阈值。
第二请求消息中携带的第一忙碌率阈值指示发送第三消息的触发事件包括触发事件c2。触发事件c2：第一信道忙碌率小于第二忙碌率阈值。
又一种可能的实施方式中，第二消息可以包括目的地址，该目的地址为专用的目的(destination)层2(layer 2，L2)标识，该专用的目的层2标识用于请求查询第一资源池的资源和第二资源池的资源是否重叠。比如第一终端设备通过广播向第二终端设备发送第二消息。
需要说明的是，本申请以下实施中的“专用的”或“专用”可以理解为指定的、网络配置的或协议预定义的。“专用”也可以表述为“特定”、“指定”等。比如，本申请实施例中的“专用目的层2标识”也可以表述为“特定目的层2标识”、“指定目的层2标识”等，其含义为：该目的层2标识仅限于某种特定的用途，不能用于其它用途。
步骤804，第二终端设备确定第一信道忙碌率。
第二终端设备确定第一信道忙碌率的方案可以参见前述步骤804中第一终端设备确定第一信道忙碌率的相关内容，不再赘述。
步骤805，第二终端设备确定第一信道忙碌率满足第一触发事件组中的至少一个触发事件。
本申请实施例中步骤805为可选择的步骤，并不是必须执行的步骤。第一触发事件组包括一个或多个触发事件，比如可以包括触发事件c1和/或触发事件c2。步骤805的相关内容可以参见前述步骤503的相关描述，不再赘述。
步骤806，第二终端设备向第一终端设备发送第三消息。第三消息包括第二指示信息，第二指示信息指示第一资源池的资源和第二资源池的资源重叠。
相对应的，第一终端设备接收第三消息。
一种可能的实施方式中，第二指示信息可以包括以下内容中的至少一项：指示第一资源池的资源和第二资源池的资源重叠的指示信息；指示第一资源池的资源受到除第一制式侧行链路传输之外的其它无线接入技术侧行链路传输干扰的指示信息；或，指示第一资源池受到第二制式侧行链路传输的干扰的指示信息。相关内容可以参见前述示例a1、示例a2和示例a3的相关内容，不再赘述。
本申请实施例中第三消息中可以包括第一信道忙碌率，也可以不包括第一信道忙碌率。当第三消息中包括第一信道忙碌率的情况下，本申请实施例中第三消息中的第一信道忙碌率和第二指示信息可以为两个信息。
又一种可能的实施方式中，第一信道忙碌率可以作为第二指示信息的一种可能的实现方式，比如第二指示信息可以包括第一信道忙碌率，再比如第二指示信息可以为第一信道 忙碌率。网络设备基于第一信道忙碌率可以确定第一资源池的资源和第二资源池的资源重叠。

步骤807，第一终端设备根据第二指示信息，确定第一资源池的资源和第二资源池的资源重叠。
值得说明的是，前述图5和图6的相关方案中涉及第一终端设备确定第一信道忙碌率的步骤，一种可能的实施方式中，第一终端设备可以基于前述方式d1、方式d2或方式d3的任一种方式计算出第一信道忙碌率。又一种可能的实施方式中，第二终端设备基于前述方式d1、方式d2或方式d3的任一种方式计算出第一信道忙碌率，第二终端设备向第一终端设备发送第一信道忙碌率，进而第一终端设备可以从第二终端设备接收第一信道忙碌率。
图8所示的方案中，步骤804也可以替换为第二终端设备确定第三信道忙碌率。步骤805也可以替换为第二终端设备确定第三信道忙碌率满足第三触发事件组中的至少一个触发事件。该场景中，第二消息可以包括第五忙碌率阈值和/或第六忙碌率阈值。
可以看出，图8所示的方案可以为前述步骤301的一种可能的实施方式。当第一终端设备无法确定第一资源池的资源和第二资源池的资源是否重叠的情况下，可以向其他终端设备查询第一资源池的资源和第二资源池的资源是否重叠，进而可以根据其他终端设备返回的结果确定第一资源池的资源和第二资源池的资源是否重叠。如此，当第一终端设备能力有限，比如无法确定第一资源池的资源和第二资源池的资源是否重叠的情况下，也可以应用本申请实施例提供的方案，可以看出，图8所示的方案可以降低对第一终端设备的要求。
值得说明的是，当图8所示的方案由同一个终端设备的两个模块执行，比如可以由第一终端设备内部的两个模块执行，该两个模块可以分别称为第一制式侧行链路传输通信模块以及第二制式侧行链路传输通信模块。当第一终端设备的第一制式侧行链路传输通信模块无法确定第一资源池的资源和第二资源池的资源是否重叠的情况下，可以向第二制式侧行链路传输通信模块查询第一资源池的资源和第二资源池的资源是否重叠，进而可以根据第二制式侧行链路传输通信模块返回的结果确定第一资源池的资源和第二资源池的资源是否重叠。
图9示例性示出了又一种通信方法的流程示意图，如图9所示，该方法包括：
步骤901，第二终端设备确定第四信道忙碌率；第四信道忙碌率指示第二制式侧行链路传输对第二资源池的资源的影响程度；
相对应地，第二终端设备接收第四信道忙碌率。
第四信道忙碌率指示第二制式侧行链路传输对第二资源池的资源的影响程度。
本申请实施例中的第四信道忙碌率可以为一个0至100的整数，可以分别对应0-1的 比例范围。
一种可能的实施方式中，第四信道忙碌率根据第四目标子信道在第二资源池的子信道中的占比确定。第四目标子信道包括第二资源池中第二制式侧行链路传输对应的接收信号强度大于第五信号强度阈值的子信道第四信道忙碌率。
比如，第二终端设备(比如处于RRC_连接态、RRC_非激活态或RRC_空闲态的第二终端设备)可以对第二侧行链路对应的接收信号强度进行测量，从而确定出第四目标子信道的数量。进而第二终端设备根据第四目标子信道的数量在第二资源池的子信道的占比确定第四信道忙碌率。
步骤902，第二终端设备确定第四信道忙碌率满足第四触发事件组中的至少一个触发事件。
其中，第四触发事件组可以包括一个或多个触发事件，比如第四触发事件组可以包括触发事件h1和/或触发事件h 2。
触发事件h1：第四信道忙碌率大于第七忙碌率阈值。
触发事件h2：第四信道忙碌率小于第八忙碌率阈值。
本申请实施例中，第七忙碌率阈值与第八忙碌率阈值不同。一种可能的实施方式中，第七忙碌率阈值可以大于第八忙碌率阈值。第七忙碌率阈值与第一忙碌率阈值、第二忙碌率阈值、第三忙碌阈值、第四忙碌阈值、第五忙碌阈值或第六忙碌阈值相同。或者，第七忙碌率阈值与第一忙碌率阈值、第二忙碌率阈值、第三忙碌阈值、第四忙碌阈值、第五忙碌阈值和第六忙碌阈值中的每一项都不同。第八忙碌率阈值与第一忙碌率阈值、第二忙碌率阈值、第三忙碌阈值、第四忙碌阈值、第五忙碌阈值或第六忙碌阈值相同。或者，第八忙碌率阈值与第一忙碌率阈值、第二忙碌率阈值、第三忙碌阈值、第四忙碌阈值、第五忙碌阈值和第六忙碌阈值中的每一项都不同。
步骤902为可选的步骤。
步骤903，第二终端设备向第一终端设备发送第四信道忙碌率。
相对应的，第一终端设备接收第四信道忙碌率。
又一种可能的实施方式中，第二终端设备向第一终端设备发送第四信道忙碌率所使用的消息可以为专门向第二终端设备发送的消息，比如该消息可以包括目的地址，该目的地址为专用的目的(destination)层2(layer 2，L2)标识，该专用的目的层2标识用于请求查询第一资源池的资源和第二资源池的资源是否重叠。比如第一终端设备通过广播向第二终端设备发送该消息，该消息也可以为前述图8的方案中的第三消息。
又一种可能的实施方式中，步骤903中，第二终端设备还可以发送第二资源池的信息，比如可以发送第二资源池的配置信息和/或第二资源池的标识信息，以使第一终端设备根据第二资源池的信息确定第四信道忙碌率为第二资源池的信道忙碌率。
步骤904，第一终端设备根据第四信道忙碌率确定第一信道忙碌率。
图9所示的方案中，步骤901也可以替换为第二终端设备确定第三信道忙碌率。步骤902也可以替换为第二终端设备确定第三信道忙碌率满足第三触发事件组中的至少一个触发事件。该场景中，步骤903中第二终端设备还可以向第一终端设备发送第三信道忙碌率。 步骤904中第一终端设备可以根据接收到的信息确定出第三信道忙碌率。
