具体实施方式
下文中将结合附图对本申请的实施例进行说明。以下结合实施例附图对本申请进行描述，所举实例仅用于解释本申请。
图1是相关技术提供的一种NR系统中两个终端的侧链路通信示意图。示例性地，终端可以为无人机。如图1所示，两个无人机可以通过物理侧链路广播信道(Physical Sidelink Broadcast Channel，PSBCH)、物理侧链路共享信道(Physical Sidelink Shared Channel，PSSCH)、物理侧链路控制信道(Physical Sidelink Control Channel，PSCCH)和物理侧链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)进行通信。在NR系统中，侧链路的发射功率可以采用功控方式进行确定。示例性地，发射功率的确定方式分为下述几种情况：
其一，在采用侧链路同步信号(Sidelink Synchronization Signals，SSS)/PSBCH块(S-SS/PBSCH Block，S-SSB)的情况下，发射功率的计算公式如下：

其二，在采用PSSCH的情况下，发射功率的计算公式如下：

其中，P CMAX为最大发射功率；P MAX,CBR为PSSCH的接收端功率目标值，其中，P MAX,CBR的取值可以由基站配置提供，否则等于最大发射功率；如果高层参数dl-P0-PSSCH-PSCCH被提供，下行的PSSCH的接收端功率目标值
Figure PCTCN2022115532-appb-000003
如果高层参数sl-P0-PSSCH-PSCCH被提供，侧链路的PSSCH的接收端功率目标值P PSSCH，D(i)＝min(P CMAX,P MAX,CBR,P PSSCH,SL(i))；否则，P PSSCH，D(i)＝min(P CMAX,P MAX,CBR)。
如果高层参数sl-P0-PSSCH-PSCCH被提供，下行的PSSCH的接收端功率目标值
Figure PCTCN2022115532-appb-000004
否则，P PSSCH，SL(i)＝min(P CMAX,P MAX,CBR)。

其四，在采用PSFCH的情况下，发射功率的计算公式如下：
如果高层参数dl-P0-PSFCH被提供，P PSFCH，one(i)＝P O,PSFCH+10log 10(2 μ)+α PSFCH·PL。
其中，P O,PSFCH指的是PSFCH的接收端功率目标值，其中，P O,PSFCH可以由高层参数dl-P0-PSFCH被提供；α PSFCH指的是PSFCH的部分路径损耗补偿因子，可以由高层参数dl-Alpha-PSFCH提供，否则为1；PL为估计的下行路径损耗。
如上，终端在不同状态下采用单一的最大发射功率作为最大发射功率上限值，造成发射功率偏高，导致干扰增加。为了有效克服终端组之间的干扰以及降低终端的功耗，本申请实施例提供一种功率确定方法，实现对侧链路的发射功率进行修正。
在一实施例中，图2是本申请实施例提供的一种功率确定方法的流程图。本实施例可以由功率确定设备执行。其中，功率确定设备可以为第一通信节点。 示例性地，第一通信节点可以为终端组中的第一终端，也可以为终端组中的第二终端。如图2所示，本实施例包括：
S210、接收配置信息，配置信息用于指示发射功率的N组功率缩减参数集合。
其中，N的取值与终端组中所包含的终端数量有关。可以理解为，N的取值等于一个终端组中所包含的终端数量。在一实施例中，终端指的是无人机，即终端组是由无人机组成的无人机群。可以理解为，N为大于或等于2的正整数。在实际通信过程中，每个终端对应一组功率缩减参数集合。在实施例中，功率缩减参数集合中包括一个或多个功率缩减参数，功率缩减参数指的是可以实现功率缩减的参数。在实施例中，第二通信节点对配置信息进行预配置，并将配置信息发送至第一通信节点。
S220、根据功率缩减参数集合中的至少一个功率缩减参数确定对应第一通信节点的发射功率。
在实施例中，第一通信节点根据对应的至少一个功率缩减参数确定对应的发射功率，实现了对发射功率的缩减，从而达到了降低系统干扰和节省第一通信节点功耗的目的。
在一实施例中，功率缩减参数集合包括以下参数中的至少之一：
与接收信号质量相关联的第一功率缩减因子、第二功率缩减因子和功率缩减量；与第一终端和终端组的相对位置相关联的第一功率缩减因子偏移量、第二功率缩减因子偏移量和功率缩减量偏移值。

在一实施例中，在第一通信节点根据自身能力等级对应的最大发射功率上限值和至少一个功率缩减参数确定对应的发射功率的情况下，第一通信节点可以不接收第二通信节点预先配置的最大发射功率上限值，也可以理解为，第二通信节点无需配置最大发射功率上限值。
