为方便理解本公开实施例，提供如下示例性实施例。
示例性实施例中，Sidelink CA中，各个载波的资源选择是独立的，资源池定义在载波上，终端先选载波，再选资源，所以，会存在终端在多个sidelink的载波上选择了时域重叠的资源。
而sidelink功率控制中，要求终端的所有的sidelink传输的总功率不超过功率阈值(下文又称为Pcmax)。对于1个sidelink载波上传输的信号和另一个载波上的上行(uplink，UL)信号时域重叠，且总功率超过Pcmax的情况，可以通过优先级比较，对于优先级较低的SL信号或者是上行信号进行功率降低。
在sidelink CA中，会有多个sidelink载波上传输的多个SL信号与上行载波上传输上行信号时域重叠，但在重叠的时域资源上，终端的多个SL信号和上行信号同时发送时总功率将超过Pcmax，此时终端如何进行上行功率控制，需要相关的方案。
方案一：把时域资源重叠的多个SL载波上传输的多个SL信号中的最低的优先级值作为整个SL的优先级，并使用该优先级值与UL信号的优先级值进行比较，降低功率采用如下方法：
Case1：当UL信号优先级值小于SL信号的优先级值时，降低SL信号的功率，此时采用如下方式：
方法1：在多个SL载波上首先对优先级值最高的SL载波上传输的SL信号进行功率降低或者放弃传输(drop)，如果在重叠的时域资源上的终端的发送总功率还是超过Pcmax，则对优先级值次高的SL载波上传输的SL信号功率降低或者放弃传输(drop)，重复这个过程，直至在重叠的时域资源上的终端的发送总功率不超过Pcmax。
方法2：在多个SL载波上首先对优先级值最高的SL载波上传输的SL信号进行功率降低，但功率不小于最低功率阈值，此时在重叠的时域资源上的终端的发送总功率还是超过Pcmax，则对优先级值次高的SL载波上传输的SL信号功率降低，且功率不小于最低功率阈值，重复这个过程，直至在重叠的时域资源上的终端的发送总功率不超过Pcmax。
在一些实施例中，最低功率阈值是预定义或预配置的。
在一些实施例中，Pcmax是预定义的，或预配置的。
Case2：当UL信号优先级值大于SL信号的优先级值时，降低UL信号的功率：
示例性地，如果sidelink CA使用2个载波，载波1上SL信号优先级值为2，载波2上SL信号优先级值为4，UL信号的优先级值为3，则把SL信号优先级值2作为整个SL信号的优先级值并与UL信号的优先级值进行比较，得到2＜3，则对UL信号进行功率降低，直到总功率不超过Pcmax。
方案二：对每个SL载波上传输的SL信号的优先级值和每个UL载波上传输的UL信号的优先级值进行优先级排序，降低功率采用如下方法：
方法1：对UL载波和SL载波中优先级值最高的信号降低功率或者放弃传输(即drop)，当在重叠的时域资源上的终端的发送总功率仍然超过Pcmax时，对优先级值次高的信号降低功率或者drop，按此规律，直到在重叠的时域资源上的终端的发送总功率不超过Pcmax。
方法2：对UL载波和SL载波中优先级值最高的信号降低功率，但功率不小于最低功率阈值，当在重叠的时域资源上的终端的发送总功率仍然超过Pcmax时，对优先级值次高的信号功率降低，但功率不小于最低功率阈值，按此规律，直到在重叠的时域资源上终端的发送总功率不超过Pcmax。
示例性地，如果SL使用2个载波，载波1上SL信号优先级值为2，载波2上SL信号优先级值值为4，UL信号的优先级值为3，则三个载波上传输的信号进行优先级排序，2＜3＜4，则首先对SL载波2上传输的SL信号进行功率降低或者drop，如果仍然超过最大功率，则对UL信号进行功率降低或者drop，按此规律，直至在重叠的时域资源上终端的发送总功率不超过Pcmax。。
示例性地，如果SL使用2个载波，SL载波1上SL信号优先级值为2，SL载波2上SL信号优先级值为4，UL使用2个载波，UL载波1上传输的UL信号的优先级值为3，UL载波2上传输的UL信号的优先级值为5，则4个载波上传输的信号进行优先级排序，2＜3＜4＜5，则首先对UL载波2上传输的UL信号进行功率降低或者drop，如果仍然超过最大功率，则对SL载波2上SL信号进行功率降低，按此规律，直到在重叠的时域资源上终端的发送总功率不超过Pcmax。
在一些实施例中，SL信号可以包括：PSFCH发送信号以及S-SSB发送信号。
在一些实施例中，PSFCH优先级由对应的PSSCH确定。
在一些实施例中，S-SSB的优先级由高层配置(预配置)(higher layer(pre)configure)确定。
在一些实施例中，PSSCH和PSCCH的优先级值为第一阶段SCI中优先级值字段来指示的。
在一些实施例中，UL信号可以包括1个或多个UL载波上的1个或多个UL信号。
在一些实施例中，在UL信号为PUSCH且优先级值为1，或UL信号为PUCCH且优先级值为1。
使用方案一，SL信号和UL信号的优先级比较具体采用如下方法：
Case1：如果第一参数sl-PriorityThreshold-UL-URLLC被提供了，把第一参数sl-PriorityThreshold-UL-URLLC的参数值看做UL信号的优先级值，多个SL载波上传输的多个SL信号中的最低的优先级值和第二参数sl-PriorityThreshold-UL-URLLC的参数值进行优先级比较。
功率降低方法采用上述的方案一中的方法1和2，当需要对第一参数sl-PriorityThreshold-UL-URLLC对应的UL信号降低功率时，即对UL信号进行功率降低，直到在重叠的时域资源上的终端的发送总功率不超过pcmax。
Case2：如果该第一参数sl-PriorityThreshold-UL-URLLC没有被配置，则UL信号比SL信号有更高的优先级，对SL信号进行功率降低，并使用方案一中的方法1或者2，直到在重叠的时域资源上的终端的发送总功率不超过pcmax。
Case 3：如果UL信号不为PUSCH且优先级值为1，或UL信号不为PUCCH且优先级值为1，把第二参数sl-PriorityThreshold的参数值看做UL信号的优先级值，把多个多个SL信号中的最低的优先级值和第二参数sl-PriorityThreshold进行优先级比较。
功率降低方法采用上述的方案一中的方法1或者方法2，当需要对第二参数sl-PriorityThreshold对应的信号降低功率时，即对UL信号进行功率降低，直到在重叠的时域资源上的终端的发送总功率不超过pcmax。
使用方案二，SL信号和UL信号的优先级比较具体采用如下方法：
Case1：如果第一参数sl-PriorityThreshold-UL-URLLC被提供了，把第一参数sl-PriorityThreshold-UL-URLLC的参数值看做UL信号的优先级值，对每个sidelink的载波上传输的SL信号的优先级值和第一参数sl-PriorityThreshold-UL-URLLC的参数值进行优先级排序。
功率降低方法采用上述的方案二中的方法1或者方法2，当需要对第一参数sl-PriorityThreshold-UL-URLLC对应的信号降低功率时，即对UL信号进行功率降低，直到在重叠的时域资源上的终端的发送总功率不超过pcmax。
Case2：如果该第一参数没有被配置，则UL信号比SL信号有更高的优先级。对多个SL信号进行优先级排序，并使用方案二中方法1或者2进行功率降低，直到在重叠的时域资源上终端的发送总功率不超过pcmax。
Case 3：如果UL信号不为PUSCH且优先级值为1，或UL信号不为PUCCH且优先级值为1，把第二参数sl-PriorityThreshold的参数值看做UL信号的优先级值，对每个SL信号的优先级值和第二参数sl-PriorityThreshold进行优先级排序。
功率降低方法采用上述的方案二中的方法1或者方法2，当需要对第二参数sl-PriorityThreshold对应的信号降低功率时，即对UL信号进行功率降低。
在一些实施例中，当多个SL信号均为PSSCH，且PSSCH在时域上和UL信号重叠时，可以复用已有的为PSSCH的SL信号与UL信号的优先级比较规则，但需要考虑多个载波上传输的PSSCH。采用如下方式：
方案一：执行1次UL信号和SL信号的比较过程，且使用所有SL载波中优先级最高的逻辑信道对应的优先级值与第二参数sl-PrioritizationThres进行比较，
Case1：当所有SL载波中优先级最高的逻辑信道对应的优先级值低于第二参数时，SL信号比UL信号优先级高，降低UL信号的功率，
Case 2：当UL信号比SL信号优先级高时，使用上述方案一中的方法1或2来降低SL信号的功率。
方案二：每个SL载波上传输的PSSCH都需要执行UL信号和SL信号的比较过程，即对每个载波上的逻辑信道最低的优先级值和第二参数sl-PrioritizationThres进行优先级排序，把第二参数sl-PrioritizationThres的参数值看做UL信号的优先级值，当需要对第二参数sl-PrioritizationThres对应的UL信号降低功率时，即对UL信号进行功率降低，功率降低使用方案二中方法1或2。
在一些实施例中，已有的为PSSCH的SL信号与UL信号的优先级比较规则：
如果满足以下条件，则媒体接入控制(medium access control，MAC)协议数据单元(protocol data unit，PDU)的传输优先于MAC实体或其他MAC实体的上行传输：
当满足如下条件时，SL信号比UL信号优先级高
1>如果MAC实体无法在传输时与所有上行链路传输同时执行此侧链路传输，并且
1>如果上层没有上行链路传输的优先级，并且
1>如果NR上行链路MAC PDU均不包含任何MAC控制元素(control element，CE)的优先级排列，以及
1>如果配置了UL-优先级Thres，并且所有NR上行链路传输的逻辑通道的最高优先级值不低于UL-优先级Thres，并且
1>如果配置了SL-优先级Thres，并且MAC PDU中逻辑通道或MAC CE的最高优先级值低于SL-优先级Thres。
注2：如果MAC实体在传输时无法与所有上行链路传输同时执行此侧链路传输，并且由于处理时间限制，在此侧链路传输之前无法获得与优先级相关的信息，则是否执行此侧链路传输取决于UE实施。
当不满足上述这些条件时，则UL信号比SL信号的传输优先级高。
