示例的，可定义16种子载波间隔组合。示例的，所定义的16种子载波间隔组合，从左至右，从上至下，先行后列可以依次编号为0至15：
{15kHz，15kHz}；{15kHz，30kHz}；{15kHz，60kHz}；{15kHz，120kHz}
{30kHz，15kHz}；{30kHz，30kHz}；{30kHz，60kHz}；{30kHz，120kHz}
{60kHz，15kHz}；{60kHz，30kHz}；{60kHz，60kHz}；{60kHz，120kHz}
{120kHz，15kHz}；{120kHz，30kHz}；{120kHz，60kHz}；{120kHz，120kHz}
可选的，网络设备可通过信令通知或预定义，在不同子载波间隔组合的优先级。比如，在子载波间隔组合1，2，3，6，7，11下，第二信号的优先级高于第一信号的优先级。子载波间隔组合4，8，9，12，13，14下，第二信号的优先级低于第一信号的优先级。上述子载波间隔组合所对应的优先级还可以是别的具体示例，本申请实施例不做限制。
在实施例五中，通过预定义或信令通知至少一种子载波间隔组合与优先级的对应关系，可满足多种帧结构参数下，第一信号和第二信号优先级确定的需求，提高传输性能。
实施例六
在本申请实施例中，第一终端设备可根据一种或多种组合下的优先级规则，确定第一信号和第二信号的优先级。所述一种或多种组合下的优先级规则，可为网络设备通过信令通知的，或者，协议规定的。所述一种或多种组合可为不同或相同帧结构参数的结合，或者，所述一种或多种组合可为不同或相同子载波间隔的结合等。
比如，对于第一信号的第一帧结构参数中的第一子载波间隔和第二信号的第二帧结构参数中的第二子载波间隔可组成一组合，该组合所对应的优先级规则可为：根据第一子载波间隔和第二子载波间隔的大小关系，确定第一信号和第二信号的优先级。
相应的，在图2所示的流程中，S201的一种具体实现可为：第一终端设备根据第一帧结构参数中的第一子载波间隔与第二帧结构参数中的第二子载波间隔的大小关系，确定第一信号和第二信号的优先级。
比如，若第一子载间隔大于(或，大于等于)第二子载波间隔，则确定第一信号的优先级较高，否则，确定第二信号的优先级较高。或者，若第一子载波间隔小于(或，小于等于)第二子载波间隔，则确定第二信号的优先级高，否则，确定第一信号的优先级高。
可选的，在上述实施例中，以根据第一子载波间隔和第二子载波间隔，确定第一信号和第二信号的优先级为例，进行说明，并不作为对本申请实施例的限定。比如，在本申请实施例中，可预定义或信令通知其它规则，确定第一信号和第二信号的优先级。

实施例七
示例的，针对上述S202的具体实现过程可为：第一终端设备根据第一信号和第二信号的优先级，确定第一信号的第一发送功率和/或第二信号的第二发送功率；第一终端设备根据第一发送功率，发送第一信号，和/或，第一终端设备根据第二发送功率，发送第二信号。
示例的，针对上述S202的具体实现过程可为：第一终端设备根据第一信号和第二信号的优先级，确定仅发送第一信号，或仅发送第二信号。
示例的，第一终端设备可确定第一终端设备是否支持第一信号和第二信号的同时传输。示例的，由于在一个时刻，在一个射频(radio frequency，RF)链路上，终端设备仅能支持一种帧结构参数信号的传输，因此，若第一信号的传输和第二信号的传输共享一个RF链路，且第一信号和第二路信号的帧结构参数不同，则可确定终端设备不支持第一信号和第二信号的同时传输。若第一信号的传输和第二信号的传输各自用不同射频链路，则无论第一信号和第二信号的帧结构参数是否相同，均可确定终端设备支持第一信号和第二信号的同时传输。
如果支持第一信号和第二信号的同时传输，则根据第一信号和第二信号的优先级，确定第一信号的第一发送功率和第二信号的第二发送功率。即第一终端设备以第一发送功率发送第一信号，和/或，第一终端设备以第二发送功率发送第二信号。
比如，若第一信号的优先级高于第二信号，则可根据第一信号的第一发送功率，调整第二信号的第二发送功率，即优先保证第一信号的第一发送功率，减少第二信号的第二发送功率或放弃第二信号的发送。可以理解的是，当将第二信号的第二发送功率调整为零时，即可认为是放弃第二信号的发送或者不发送第二信号。若第二信号的优先级高于第一信号，则可根据第二信号的第二发送功率，调整第一信号的第一发送功率，即优先保证第二信号的第二发送功率，调整第一信号的第一发送功率或放弃第一信号的发送。可以理解的是，当将第一信号的第一发送功率调整为零时，即可认为是放弃第一信号的发送或不发送第一信号。可选的，在本申请实施例中，放弃信号或信息的发送，也可认称为放弃信号或信息。比如，放弃第二信号的发送，也可以称丢弃第二信号。放弃第一信号的发送，也可以称为丢弃第一信号。
在本申请实施例中，根据第一信号的发送功率调整第二信号的第二发送功率，或者根据第二信号的发送功率调整第一信号的第一发送功率，包括：使得终端设备的发送功率不超过最大发射功率。终端设备根据一个信号调整另一个信号的发送功率的方法类似LTE的协议36.213或NR协议38.213中根据PUCCH的发送功率调整PUSCH的发送功率的方法，或者根据PUSCH的发送功率调整PUCCH的发送功率的方法，或者，根据PSCCH的发送功率调整PSSCH的发送功率的方法，或者，根据PSSCH的发送功率调整PSCCH的发送功率的方法，或者其它调整方法，本申请实施例不做限制。
如果不支持第一信号和第二信号的同时传输，则根据第一信号和第二信号的优先级，确定发送第一信号或者发送第二信号。比如，若第一信号的优先级高于第二信号，则第一终端设备可仅传输第一信号，否则，第一终端设备仅传输第二信号。
示例的，如图3a和图3b所示，设定第一终端设备不支持第一信号和第二信号的同时传输。第一信号为上行信号，第一信号对应第一帧结构参数，第一帧结构参数中的子载波间隔为15kHz。在15kHz的子载波间隔下，1个时隙的时长为1ms。第二信号为旁链路信 号，第二信号对应第二帧结构参数，第二帧结构参数中的子载波间隔为60kHz。在60kHz下，1个时隙的时长近似为0.25ms。通过图3a或图3b可以看出，在15kHz的子载波间隔下1个时隙的长度，等于60kHz的子载波间隔下的4个时隙的长度。
如图3b所示，采用上述图2流程所示的方法，确定上行信号的优先级高于旁链路信号的优先级，终端设备可先采用60kHz的子载波间隔发送旁链路信号，然后进行RF切换(RF switching)，所述RF切换可指由60kHz的子载波间隔切换到15kHz的子载波间隔，随后以15kHz的子载波间隔发送上行信号。其中，所述RF切换需要3个60kHz子载波间隔下的时隙。通过图3b可以看出，上行信号的传输时延(transmission delay)为15kHz子载波间隔下的一个时隙，为1ms。
如图3a所示，如果未采用图2流程所公示的方法，固定认为上行信号的优先级高于旁链路信号的优先级，终端设备可先采用15kHz的子载波间隔发送上行信号，进行RF切换，所述RF切换指由15kHz的子载波间隔切换到60kHz的子载波间隔，随后以60kHz的子载波间隔发送旁链路信号。通过图3a可以看出，旁链路信号的传输时延近似为1.75ms。
通过图3a与图3b对比可以看出，采用本申请图2流程所公开的方法，可减小传输时延。
可选的，在图2所示的方法中，还包括：第一终端设备进行RF切换(例如从用于发送第一信号的RF切换为用于发送第二信号的RF；或者从用于发送第二信号的RF切换为用于发送第一信号的RF)，所述RF切换的取值可以等于BWP切换时延。所述BWP切换时延可指BWP切换所需要的时间，在BWP切换时延内，终端设备不能收发信号。如表3所示，在不同的帧结构参数μ下，BWP切换时延不同。
仍可参照表3所示，当帧结构参数μ取值为0时，对应15kHz的子载波间隔，一个时隙的长度为1ms，在类型1下BWP切换时延为1个时隙，在类型2下BWP切换时延为3个时隙。当帧结构参数μ取值为1时，对应30kHz的子载波间隔，一个时隙的长度为0.5ms，在类型1下BWP切换时延为2个时隙，在类型2下BWP切换时延为5个时隙。当帧结构参数μ取值为2时，对应60kHz的子载波间隔，一个时隙的长度近似为0.25ms，在类型1下BWP切换时延为3个时隙，在类型2下BWP切换时延为9个时隙。当帧结构参数μ取值为3时，对应120kHz的子载波间隔，一个时隙的长度近似为0.125ms，在类型1下BWP切换时延为6个时隙，在类型2下BWP切换时延为17个时隙。可选的，当终端设备的能力支持类型1时，所述BWP切换时延的取值为类型1所对应的BWP切换时延。当终端设备的能力支持类型2时，所述BWP切换时延的取值为类型2所对应的BWP切换时延。
示例的，终端设备从BWP1切换至BWP2，BWP1和BWP2的帧结构参数μ相同，可根据表3所示的BWP切换时延，确定BWP的切换时延。比如，如果BWP1和BWP2的帧结构参数μ的取值为0，且终端设备支持类型1的BWP切换时延时，则所述BWP的切换时延为15kHz子载波间隔下的1个时隙，对应1ms。
示例的，终端设备从BWP1切换到BWP2，BWP1和BWP2的帧结构参数μ不同。设定BWP1的帧结构参数为第一帧结构参数，第一帧结构参数对应第一子载波间隔。BWP2的帧结构参数为第二帧结构参数，第二帧结构参数对应第二子载波间隔。若第一子载波间隔大于第二子载波间隔，则根据第一帧结构参数，确定BWP切换时延。若第二子载波间隔大于第一子载波间隔，则根据第二帧结构参数，确定BWP切换时延。具体如果根据第一帧结构参数或第二帧结构参数，确定BWP切换时延，可参见上述表3的描述。
比如，如果BWP1的子载波间隔为15kHz(μ的取值为0)，BWP2的子载波间隔为60kHz(μ的取值为2)，则BWP1到BWP2的切换时延为60kHz对应的切换时延，比如类型1下BWP切换时延为60kHz的子载波间隔下的3个时隙，类型2下BWP切换时延为60kHz的子载波间隔下的9个时隙。

进一步，需要说明的是，在不同子载波间隔下，时隙的长度不同。例如，如图4所示，在15kHz的子载波间隔下的1个时隙，等于30kHz的子载波间隔下的2个时隙，等于60kHz的子载波间隔下的4个时隙，等于120kHz的子载波间隔下的8个时隙。

实施例九
本申请实施例所提供的方案，可应用于载波聚合(carrier aggregation，CA)的场景。示例的，在CA中可以包括主小区(primary cell，PCell)和辅小区(secondary cell，SCell)，当第一信号和第二信号在不同的载波中传输时，第一终端设备可根据主小区和辅小区的优先级，确定第一信号与第二信号的优先级。即在上述图2所示的流程中，S201可替换为： 第一终端设备根据主小区和辅小区的优先级，确定第一信号和第二信号的优先级。
示例性地，当主小区的优先级高于辅小区的优先级时，若主小区用于传输第一信号，辅小区用于传输第二信号，则第一信号的优先级高于第二信号的优先级。同理，若主小用于传输第二信号，辅小区用于传输第一信号，则第二信号的优先级高于第一信号的优先级。
示例性地，本申请实施例也可以结合小区标识确定优先级，比如小区标识小的优先级高于小区标识大的优先级时，如果小区标识小的小区上传输第一信号，小区标识大的小区上传输第二信号，则第一信号的优先级高于第二信号的优先级。同理，如果小区标识小的小区上传输第二信号，小区标识大的小区上传输第一信号，则第二信号的优先级高于第一信号的优先级。
示例性地，本申请实施例也可以结合小区标识确定优先级，比如小区标识大的优先级高于小区标识小的优先级时，如果小区标识大的小区上传输第一信号，小区标识小的小区上传输第二信号，则第一信号的优先级高于第二信号的优先级。同理，如果小区标识大的小区上传输第二信号，小区标识小的小区上传输第一信号，则第二信号的优先级高于第一信号的优先级。
可以理解的是，在本示例中，确定第一信号和第二信号的优先级后，如何传输第一信号和第二信号，可参见上述图2所示流程的记载，不此不再说明。
实施例十
本申请实施例所提供的方案，可应用于双链接(dual-connectivity，DC)的场景。示例的，针对DC场景，终端设备的小区可以包括主小区组(master cell group，MCG)和辅小区组(secondary cell group，SCG)。主小区组中的主小区称为主小区PCell，剩余小区为辅小区SCell。辅小区组中的主小区称为主辅小区(primary secondary cell，PSCell)，剩余小区为辅小区SCell。当第一信号和第二信号在不同的小区中传输时，即在上述图2所示的流程中，S201可替换为：第一终端设备根据主小区PCell、主辅小区PSCell和/或辅小区SCell的优先级，确定第一信号和第二信号的优先级。
比如，当主小区PCell的优先级高于主辅小区PSCell的优先级，主辅小区PSCell的优先级高于辅小区SCell的优先级时，若主小区用于传输第一信号时，主辅小区和/或辅小区用于传输第二信号时，所述第一信号的优先级高于第二信号的优先级。若主小区用于传输第二信号，主辅小区和/或辅小区用于传输第一信号，则第二信号的优先级高于第一信号的优先级。
针对上述DC的场景，可能会出现有些小区配置PUCCH，有些小区不配置PUCCH的情况，针对该情况，可根据小区是否配置PUCCH确定第一信号和第二信号的优先级。比如，第一小区配置PUCCH，第二小区未配置PUCCH，第一小区的优先级高于第二小区的优先级，若第一小区用于传输第一信号，第二小区用于传输第二信号，则第一信号的优先级高于第二信号的优先级。若第一小区用于传输第二信号，第二小区用于传输第一信号，则第二信号的优先级高于第一信号的优先级。
可以理解的是，在本示例中，确定第一信号和第二信号的优先级后，如何传输第一信号和第二信号，可参见上述图2所示流程的记载，不此不再说明。

示例的，在本申请实施例中的上述描述中，网络设备通过信令通知，也可以替换为运营商通过信令通知。比如，运营商可以通过预配置信令通知终端设备，或者运营商可以在终端的用户识别(subscriber identification module，SIM)或全球用户识别(universal subscriber identity module，USIM)中写入预配置信令，终端可以通过读取SIM或USIM，获取预配置信令等。
其中，SIM可以是用户识别卡，也称为用户身份识别卡、智能卡等。USIM可以是全球用户识别的缩写，也可以叫做升级SIM。
可选的，如果终端设备可以接收多个配置信令，比如包括预配置信令，系统信息，公共RRC信令，UE专用RRC信令，DCI信令等。所述多个配置信令中的一个或多个信令可以被其他信令覆盖，比如根据如下规则进行信令覆盖：

示例的，根据上述信令覆盖规则：比如，如果终端设备接收到DCI信令和预配置信令，且该两个信令对相同的参数进行了配置，则终端设备以DCI信令中的参数值为准；如果终端设备可以接收到UE专用RRC信令和预配置信令，且该两个信令对相同的参数进行了配置，则终端设备以UE专用RRC信令中的参数值为准；如果终端设备可以接收到系统信息和预配置信令，且该两个信令对相同的参数进行了配置，则UE以系统信息中的参数值为准等。
实施例十一
针对图2所示提供的通信方法的流程，本申请提供一应用场景，该应用场景并不作为对本申请实施例的限定。在该应用场景中，以第一信号为上行信号，对应上行传输，第二信号为旁链路信号，对应旁链路传输为例，进行说明。
针对上行传输和旁链路传输，可能会存在如下的场景：上行信号在UL BWP中传输，旁链路信号在SL BWP中传输。当两者的子载波间隔不同或传输带宽不在终端设备的射频带宽内时，在一个时刻，终端设备有可能只能发送上行信号或发送旁链路信号。而如果需要发送另一个信号，需要进行射频的切换，切换需要一定的时延，在该时延内，终端设备不能进行信号的收发。如果不考虑帧结构参数下的优先级，会导致传输时延较大，可用传输资源降低，影响信号的传输性能。而本申请实施例图2所提供的通信方法，考虑根据不同帧结构参数，确定上行信号和旁链路信号的优先级，从而可减少传输时延，提高传输资源利用率，提高信号的传输性能。
示例中，本申请上述实施例七中提供的RF切换，可包括以下RF切换中的一种或多个。
情况1：仅切换射频带宽位置
比如，射频带宽位置从包含SL BWP的带宽位置切换到包含UL BWP的带宽位置，或者从包含UL BWP的带宽位置切换到包含SL BWP的带宽位置。
如图5a所示，SL BWP为60kHz子载波间隔，UL BWP为60kHz子载波间隔，因为射频带宽内仅有一个BWP的资源。因此在同一时间单元内，终端设备不能同时传输上行 和旁链路信号。比如在时隙n，终端设备在UL BWP中传输上行信号，为了在时隙m上传输旁链路信号，射频带宽需要从时隙n的位置切换到时隙m的位置。射频带宽切换需要一定的时延，在该时延内，终端设备不能收发。
情况2：仅切换帧结构参数(比如子载波间隔)
比如，从SL BWP的帧结构参数切换到UL BWP的帧结构参数，或者从UL BWP的帧结构参数切换到SL BWP的帧结构参数。
如图5b所示，SL BWP为30kHz子载波间隔，UL BWP为60kHz子载波间隔，因为同一时间单元终端设备有可能仅支持一种帧结构参数的信号的传输。因此在同一时间单元，终端设备不能同时传输上行信号和旁链路信号。比如在时隙n，终端设备在UL BWP中传输上行信号，为了在时隙m上传输旁链路，子载波间隔需要从60kHz切换到30kHz。子载波间隔变换可能需要一定的时延，在该时延内，终端设备不能收发。
情况3：切换射频带宽位置以及帧结构参数
比如，射频带宽位置从包含SL BWP的带宽位置切换到包含UL BWP的带宽位置，从SL BWP的帧结构参数切换到UL BWP的帧结构参数；或者从包含UL BWP的带宽位置切换到包含SL BWP的带宽位置，从UL BWP的帧结构参数切换到SL BWP的帧结构参数。
如图5c所示，SL BWP为30kHz子载波间隔，UL BWP为60kHz子载波间隔，因为同一时间单元内，终端设备有可能仅支持一种帧结构参数的信号的传输，且射频带宽内仅有一个BWP的资源。因此在同一时间单元内，终端设备不能同时传输上行信号和旁链路信号。比如在时隙n，终端设备在UL BWP中传输上行信号，为了在时隙m上传输旁链路信号，子载波间隔需要从60kHz切换到30kHz，射频带宽需要从时隙n的位置切换到时隙m的位置。射频变换需要一定的时延，在该时延内，终端设备不能收发。
关于上述情况1至情况3中的切换时延，可具体参见上述实施例七中的表3所示，在此不再说明。
上述本申请提供的实施例一至实施例十一中，分别从网络设备、终端、网络设备和终端之间交互、以及终端和终端交互的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，网络设备和终端可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
