本申请中，SL可以是指侧链路，即SL可以是指终端设备与终端设备之间通过PC5接口 实现直接通信的通信链路，或者发送终端设备与接收终端设备之间通过PC5接口实现直接通信的通信链路。例如，发送终端设备可以为图1a至图1d所示的终端设备112，接收终端设备可以为图1a至图1d所示的终端设备113，即终端设备112与终端设备113之间的通信链路可以为SL。
本申请中，SL的传输状态信息用于指示SL上的通信数据传输情况。一个可选的实施方式中，SL的传输状态信息可以包括但不限于SL的信号质量信息、接收终端设备的反馈信息、丢包率、包传输时延中的一项或多项。
其中，SL的信号质量信息用于指示SL的通信链路信号质量(或简称为SL上的信号质量)。其中，SL的信号质量信息可以包括但不限于参考信号接收质量(Reference Signal Receiving Quality，RSRQ)和参考信号接收功率(Reference Signal Receiving Power，RSRP)中的一项或多项。
其中，接收终端设备的反馈信息用于指示接收终端设备的数据包接收情况。其中，该反馈信息包括确定应答(Acknowlegde，ACK)和/或否定应答(Negative Acknowledge，NACK)。其中，ACK表示接收终端设备接收数据包成功，NACK表示接收终端设备接收数据包失败。也就是说，在发送终端设备发送数据包给接收终端设备后，如果接收终端设备接收数据包成功，接收终端设备的反馈信息为ACK。如果接收终端设备接收数据包失败，接收终端设备的反馈信息为NACK。可选的，该反馈信息用于指示历史数据包的接收情况信息。可选的，接收终端设备的反馈信息可以包括接收终端设备的介质访问控制(Media Access Control，MAC)层的反馈信息，即在发送终端设备发送数据包给接收终端设备后，接收终端设备可以通过MAC层的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈机制给发送终端设备反馈反馈信息。可选的，接收终端设备的反馈信息还可以包括无线链路控制(Radio Link Control，RLC)层的反馈信息，即在发送终端设备发送数据包给接收终端设备后，接收终端设备可以通过RLC层的反馈机制给发送终端设备反馈反馈信息。
其中，丢包率是指SL上一段时间内接收终端设备接收失败的数据包的个数与传输的数据包的总数之间的比率。
其中，包传输时延是指SL上数据包从发送终端设备传输到接收终端设备的时长。
可选的，上述所述的接收终端设备的反馈信息、丢包率以及包传输时延等可以反映SL上数据包的传输状态。SL的信号质量信息用于指示SL上的信号质量，SL信号质量的好坏能影响数据传输的状态，比如，信号质量好，SL的数据传输状态就好，反之，则差。因此，SL的传输状态信息用于指示SL上的通信数据传输情况，可以表述为：SL的传输状态信息可用于指示SL的信号质量和/或SL上的数据包传输状态。
本申请中，在SL网络中，资源调度有两种模式：分布式资源调度模式(可简称为“mode2”的资源调度模式)和集中式资源调度模式(可简称为“mode1”的资源调度模式)。也可以说，资源分配有两种模式：分布式资源分配模式和集中式资源分配模式。其中，分布式资源调度模式是指网络设备给终端设备配置了资源池，终端设备可以在所配置的资源池中自行选择传输资源。其中，集中式资源调度模式是指网络设备实时动态的给终端设备调度传输资源。
可选的，分布式资源调度模式可以适用于处于网络覆盖范围之内的终端设备(如图1c所示的终端设备112)或者处于网络覆盖范围之外的终端设备(如图1c所示的终端设备113)。
可选的，集中式资源调度模式可以适用于处于网络覆盖范围之内的终端设备(如图1c所示的终端设备112)。
下面结合附图对本申请实施例进行阐述。
请参见图2，图2示出了一种通信方法的流程示意图，该通信方法可以应用于图1a-图1d所示的通信系统或者与图1a-图1d所示通信系统类似的其他系统。该通信方法可基于SL的传输状态信息，激活或去激活SL的包复制功能。可选的，该通信方法可应用于发送终端设备或网络设备，如图2所示，该通信方法可以包括但不限于S201-S202：
S201：获取SL的传输状态信息。
S202：根据SL的传输状态信息，激活或去激活SL的包复制功能。
一个可选的实施方式中，S202可包括：在SL的传输状态信息满足第一条件至第四条件中的一个或多个的情况下，激活SL的包复制功能；在SL的传输状态信息满足第五条件至第八条件中的一个或多个的情况下，去激活SL的包复制功能。
可选的，该第一条件可以为SL的传输状态信息中RSRQ小于第一阈值，或SL的传输状态信息中RSRP小于第二阈值，或SL的传输状态信息中RSRQ小于第一阈值且RSRP小于第二阈值。可选的，该第二条件可以为SL的传输状态信息中包括的NACK的反馈信息的数量大于第三阈值，或SL的传输状态信息中包括的ACK的反馈信息的数量小于第四阈值，或SL的传输状态信息中包括的NACK的反馈信息的数量大于第三阈值且ACK的反馈信息的数量小于第四阈值。可选的，该第三条件可以为SL的传输状态信息中丢包率大于第五阈值。可选的，该第四条件可以为SL的传输状态信息中包传输时延大于第六阈值。
也就是说，SL的数据包传输状态较差，如上述所述的SL的传输状态信息包括的一项或多项参数表征SL上的数据包传输状态较差的情况，或者SL的信号质量较差，如上述所述的SL的信号质量信息包括的一项或多项参数表征SL的通信链路信号质量较差的情况，可激活SL的包复制功能。
可选的，该第五条件可以为SL的传输状态信息中RSRQ大于等于第一阈值，或SL的传输状态信息中RSRP大于等于第二阈值。可选的，该第六条件可以为SL的传输状态信息中包括的NACK的反馈信息的数量小于等于第三阈值，或SL的传输状态信息中包括的ACK的反馈信息的数量大于等于第四阈值。可选的，该第七条件可以为SL的传输状态信息中丢包率小于等于第五阈值。可选的，该第八条件可以为SL的传输状态信息中包传输时延小于等于第六阈值。
也就是说，SL的数据包传输状态较好，如上述所述的SL的传输状态信息包括的一项或多项参数表征SL上的数据包传输状态较好的情况，或者SL的信号质量较好，如上述所述的SL的信号质量信息包括的一项或多项参数表征SL的通信链路信号质量较好的情况，可去激活SL的包复制功能。
可选的，上述第一阈值、第二阈值、第三阈值、第四阈值、第五阈值和第六阈值中的一个或多个可以是预定义的，也可以是网络设备配置的，还可以是网络设备和终端设备协商确定或者协议规定的，本申请不作限制。
一个可选的实施方式中，SL的包复制功能处于激活状态，这样，执行步骤S202时可去激活SL的包复制功能。例如，配置了包复制功能时，可默认激活包复制功能，即配置了包复制功能时，该SL的包复制功能处于激活状态，进而，可执行步骤S202去激活SL的包复制功能。
另一个可选的实施方式中，SL的包复制功能处于去激活状态，这样，执行步骤S202时可激活SL的包复制功能。例如，配置了包复制功能时，默认未激活SL的包复制功能，这样，可执行步骤S202激活SL的包复制功能。
其中，配置了包复制功能可以是发送终端设备具有配置信息，该配置信息用于配置该发 送终端设备执行包复制功能时所需满足的条件和/或所需要用到的参数等。可选的，该配置信息可以是网络设备为终端设备配置的，或者是预配置的。
综上，图2所示的通信方法，可以根据SL的传输状态信息灵活的激活或去激活包复制功能。由于SL的传输状态信息可以指示SL上的通信数据传输情况，即可以指示SL的数据包传输状态或者SL的信号质量，根据SL的数据包传输状态或者SL的信号质量确定是否激活包复制功能，可以使得数据包的传输与SL的数据包传输状态或者SL的信号质量适配，从而提高数据传输可靠性或者提高数据传输效率。比如，在SL的数据包传输状态较差或者SL的信号质量较差时，此时可以激活包复制功能，提升数据传输的可靠性，在SL的数据包传输状态较好或者SL的信号质量较好时，此时，可以去激活包复制功能，从而提高数据传输效率，降低传输资源的浪费。
本申请中，图2所示的通信方法可以应用于发送终端设备。例如，发送终端设备可以执行图2所示的S201-S202，发送终端设备根据SL的传输状态信息，灵活的激活或去激活SL的包复制功能，即由发送终端设备决策激活或去激活SL的包复制功能。其中，该发送终端设备可以为SL中处于分布式资源调度模式的终端设备。由于处于分布式资源调度模式，故发送终端设备可在所配置的资源池中自行选择传输资源，相应的，由发送终端设备自行决策激活或去激活SL的包复制功能。
本申请中，图2所示的通信方法可应用于网络设备，即网络设备可根据SL的传输状态信息，激活或去激活SL的包复制功能，即由网络设备决策激活或去激活SL的包复制功能。其中，该发送终端设备可以为SL中处于集中式资源调度模式的终端设备。由于处于集中式资源调度模式，故需要网络设备实时动态的给发送终端设备调度传输资源，因此可由网络设备决策激活或去激活SL的包复制功能。
请参见图3，图3所示出了一种通信方法的流程示意图。图3所示的通信方法中以网络设备决策激活或去激活该SL的包复制功能为例，进行阐述。如图3所示，该通信方法可以包括但不限于S301-S303：

可选的，在指示信息用于指示发送终端设备激活SL的包复制功能的情况下，发送终端设备激活SL的包复制功能。在指示信息用于指示发送终端设备去激活SL的包复制功能的情况下，发送终端设备去激活SL的包复制功能。
可见，图3所示的通信方法中，发送终端设备可向网络设备发送，发送终端设备与接收终端设备之间SL的传输状态信息，网络设备可根据SL的传输状态信息生成指示信息，从而有利于发送终端设备根据该指示信息灵活的激活或去激活包复制功能。由于SL的传输状态信息可以指示SL上的通信数据传输情况，即可以指示SL的数据包传输状态或者SL的信号质量，网络设备可以根据SL的数据包传输状态或者SL的信号质量，确定激活或去激活包复制功能的指示信息，进而发送终端设备根据该指示信息激活或去激活包复制功能，使得数据包的传输与SL的数据包传输状态或者SL的信号质量适配，从而提高数据传输可靠性或者提高数据传输效率。比如，在SL的数据包传输状态较差或者SL的信号质量较差时，网络设备可以发送激活包复制功能的指示信息，发送终端设备可基于该指示信息激活包复制功能，从而提升数据传输的可靠性。在SL的数据包传输状态较好或者说SL的信号质量较好时，数据包的可靠性也会较高，此时，网络设备可以发送去激活包复制功能的指示信息，发送终端设备可基于该指示信息去激活包复制功能，从而提高数据传输效率，降低传输资源的浪费。
请参见图4，图4示出了另一种通信方法的流程示意图，该通信方法可以应用于图1a-图1d所示的通信系统或者与图1a-图1d所示通信系统类似的其他系统。该通信方法可基于指示信息，激活或去激活SL的包复制功能。如图4所示，该通信方法可以包括但不限于S401-S402：
S401：接收指示信息，其中，该指示信息用于指示激活或去激活SL的包复制功能。
对应的，该通信方法还可以包括发送指示信息的步骤。
例如，接收终端设备可发送指示信息，相应的，发送终端设备可执行步骤S401，接收该指示信息。可选的，接收终端设备可以通过PC5接口的RRC信令向发送终端设备发送该指示信息。可选的，该指示信息可以为PC5接口的RRC信令中的一字段。

S402：根据指示信息，激活或去激活SL的包复制功能。
一个可选的实施方式中，SL的包复制功能处于激活状态，例如，配置了包复制功能时，可默认激活包复制功能，即配置了包复制功能时，该SL的包复制功能处于激活状态，这样，指示信息若指示了去激活SL的包复制功能，执行步骤S402时可去激活SL的包复制功能。
另一个可选的实施方式中，SL的包复制功能处于去激活状态，例如，配置了包复制功能时，可默认包复制功能未激活，即配置了包复制功能时，该SL的包复制功能处于未激活状态，这样，指示信息若指示了激活SL的包复制功能，执行步骤S402时可激活SL的包复制功能。
综上，图4所示的通信方法可以根据指示信息灵活的激活或去激活包复制功能。由于SL的传输状态信息可以指示SL上的通信数据传输情况，即可以指示SL的数据包传输状态或者SL的信号质量，根据SL的数据包传输状态或者SL的信号质量确定指示信息，以指示激活或去激活包复制功能，可以使得数据包的传输与SL的数据包传输状态或者SL的信号质量适配，从而提高数据传输可靠性或者提高数据传输效率。比如，在SL的数据包传输状态较差或者SL的信号质量较差时，此时确定的指示信息可用于指示激活包复制功能，提升数据传输的可靠性，在SL的数据包传输状态较好或者SL的信号质量较好时，此时，确定的指示信息可用于指示去激活包复制功能，从而提高数据传输效率，降低传输资源的浪费。

另一种可行的实现方式中，发送终端设备可接收来自网络设备的指示信息，根据指示信息激活或去激活SL的包复制功能。该实现方式对应的实施例可参见图4所示的通信方法。可选的，发送终端设备接收来自网络设备的指示信息之前，可上报SL的传输状态信息，即对应图3所示的通信方法，此处不再详述。图3所述的通信方法中，发送终端设备可为SL中处于集中式资源调度模式的终端设备，这样，需要网络设备实时动态的给发送终端设备调度传输资源，相应的，是由网络设备自行决策激活或去激活SL的包复制功能。
本申请中，图4所示的通信方法如上述举例可知，可应用于网络设备，即网络设备可以执行图4所示的S401-S402，接收指示信息，并根据该指示信息激活或去激活SL的包复制功能。该实现方式对应的实施例可参见图6所述的通信方法。图6所述的通信方法与图3所述的通信方法的不同之处在于，网络设备是接收到发送终端设备上报的指示信息后，再指示发送终端设备激活或去激活SL的包复制功能，而不是如图3所示的网络设备接收到发送终端设备上报的SL的传输状态信息后，再指示发送终端设备激活或去激活SL的包复制功能。相应的，图6所述的通信方法中，发送终端设备可为SL中处于集中式资源调度模式的终端设备，这样，需要网络设备实时动态的给发送终端设备调度传输资源，相应的，是由网络设备自行决策激活或去激活SL的包复制功能。

请参见图6，图6示出了一种通信方法的流程示意图。图6所示的通信方法中以网络设备可接收来自发送终端设备的指示信息为例，进行阐述的。为了便于阐述，将网络设备接收来自发送终端设备的指示信息称为第一指示信息，将网络设备发送给发送终端设备的指示信息称为第二指示信息。如图6所示，该通信方法可以包括但不限于S601-S603：
S601：发送终端设备向网络设备发送第一指示信息；对应的，网络设备接收该第一指示信息。
其中，第一指示信息用于指示发送终端设备建议或推荐激活或去激活SL的包复制功能。可选的，在SL的数据包传输状态较好，如上述所述的SL的传输状态信息包括的一项或多项参数表征SL上的数据包传输状态较好的情况，或者SL的信号质量较好，如上述所述的SL的信号质量信息包括的一项或多项参数表征SL的通信链路信号质量较好的情况，发送终端设备可发送第一指示信息，以建议或推荐去激活SL的包复制功能。在SL的数据包传输状态较差，如上述所述的SL的传输状态信息包括的一项或多项参数表征SL上的数据包传输状态较差的情况，或者SL的信号质量较差，如上述所述的SL的信号质量信息包括的一项或多项参数表征SL的通信链路信号质量较差的情况，发送终端设备可发送第一指示信息，以建议或推荐激活SL的包复制功能。
可选的，发送终端设备可基于SL的传输状态信息确定第一指示信息；或者，发送终端设备可接收来自接收终端设备的指示信息(如称为第三指示信息，即基于接收终端设备指示的激活或去激活SL包复制功能)确定第一指示信息。
其中，针对基于SL的传输状态信息确定该第一指示信息的方式，在SL的传输状态信息满足第一条件至第四条件中的一个或多个的情况下，第一指示信息用于指示建议或推荐激活SL的包复制功能。在SL的传输状态信息满足第五条件至第八条件中的一个或多个的情况下，第一指示信息用于指示建议或推荐去激活SL的包复制功能。其中，第一条件至第八条件的相关阐述可参见图2所述的相关内容，此处不再详述。
其中，接收终端设备基于SL的传输状态信息确定第三指示信息的相关内容，可参见上述对应实施方式的阐述，此处不再详述。
一个可选的实施方式中，发送终端设备执行S601可以触发网络设备执行S602。
S602：网络设备向发送终端设备发送第二指示信息，对应的，发送终端设备接收第二指示信息，该第二指示信息用于指示激活或去激活SL的包复制功能。
也就是说，第二指示信息是网络设备决策的激活或去激活SL的包复制功能的指示信息。
其中，网络设备根据第一指示信息，确定第二指示信息。例如，若第一指示信息指示建议或推荐激活SL的包复制功能，若网络设备同意激活，则确定的第二指示信息用于指示激活SL的包复制功能；若第一指示信息指示建议或推荐去激活SL的包复制功能，若网络设备同意去激活，则确定的第二指示信息用于指示去激活SL的包复制功能。可选的，若网络设备不同意第一指示信息建议或推荐的状态，第二指示信息可不必与第一指示信息保持一致， 此处不再详述。
S603：发送终端设备根据第二指示信息激活或去激活SL的包复制功能。
一种可选的实施方式中，在第二指示信息用于指示发送终端设备激活SL的包复制功能的情况下，发送终端设备激活SL的包复制功能。在第二指示信息用于指示发送终端设备去激活SL的包复制功能的情况下，发送终端设备去激活SL的包复制功能。
可见，图6所示的通信方法，发送终端设备根据来自网络设备的第二指示信息，灵活的激活或去激活包复制功能。由于SL的传输状态信息可以指示SL上的通信数据传输情况，即可以指示SL的数据包传输状态或者SL的信号质量，发送终端设备根据SL的数据包传输状态或者SL的信号质量确定第一指示信息，以指示是否激活包复制功能，进而网络设备可根据第一指示信息确定第二指示信息，使得在考虑SL的数据包传输状态或者SL的信号质量同时，还可考虑网络设备自己的决策，从而有利于网络设备进行全局决策，以提高数据传输可靠性或者提高数据传输效率。比如，在SL的数据包传输状态较差或者SL的信号质量较差时，此时第一指示信息可以建议或推荐激活包复制功能，网络设备可基于第一指示信息，考虑是否通过包复制功能提升数据传输的可靠性；在SL的数据包传输状态较好或者SL的信号质量较好时，此时，第一指示信息可以建议或推荐去激活包复制功能，网络设备可基于第一指示信息，考虑是否需提高数据传输效率，降低传输资源的浪费。
