本申请涉及无线通信技术领域，例如涉及一种上行元素发送功率确定方法、装置、设备和存储介质。
背景技术
在波束通信中，为了提高通信链路的鲁棒性，常采用多个发送波束重复发送同一份数据，此时让第一信道探测参考信号(Sounding Reference Signal，SRS)资源的空间关系参考信息包括多个SRS资源，第一SRS资源的空间发送滤波器通过多个SRS资源确定，每个上行解调参考信息(Demodulation Reference Signal，DMRS)端口对应于一个第一SRS资源，上行DMRS端口的参数通过第一SRS资源得到，在上行物理共享信道(Physical Uplink Shared Channel，PUSCH)的DMRS之前发送第一SRS作为中间过渡，这样会增加SRS的发送负载。在另一种方法中，让不同的发送波束对应不同的DMRS端口，但是增加了DMRS负载，如何在保障通信链路鲁棒性的基础上，节省DMRS负载以及终端的发送负载成为业界研究的重点。类似地，对于下行，为了采用多个发送波束重复发送一份数据，采用多个DMRS端口，不同DMRS端口对应不同的传输配置指示状态(Transmission Configuration Indication state，TCI state)，但是此时会增加DMRS负载，也让一个DMRS端口对应多个TCI state，此时层到DMRS端口的映射关系，准共址(Quasi Co-Location，QCL)关系如何成为研究的重点。

乘以功率以后映射到PRB资源上，在天线端口[p 0，p 0，...，p v-1]上发送PUSCH给基站，其中，x j(i)可以是PUSCH的第j层数据。
或者，PUSCH DMRS1的发送功率，基于{SRS资源1和SRS资源4}对应的两套功率参数分别一个发送功率，总共得到两个发送功率，然后在SRS资源1和SRS资源4上分别采用的对应的功率发送DMRS端口1。因为此时是在相同RE上在SRS资源1和SRS资源4对应的发送波束上发送DMRS1，根据SRS资源1和SRS资源4分别得到的发送功率总和会超过终端的最大发送功率，当两个发送功率和大于预定值的情况下，需要对于两个发送功率中的每个发送功率或者对其中的一个发送功率施加一个功率缩放因子。此时一个DMRS在相同的RE上对应两个发送功率。此时层到发送天线端口的映射公式如公式(1-1)所示：

所述Y个天线端口中的各天线端口对应的解调参考信号和所述天线端口对应的PDSCH之间的功率差。
在本申请实施例中，可以通过比较各天线端口对应的DMRS与PDSCH之间功率确定功率差，可以将该功率差作为天线端口与PDSCH之间的功率差。
例如，在上述申请实施例的基础上，还包括以下特征：下行解调参考信号端口对应Y个天线端口，所述Y个天线端口对应所述下行解调参考信号端口的相同资源；根据下行解调参考信号端口在相同资源上对应的TCI状态的个数确定层到端口的映射关系。
例如，下行解调参考信号端口对应多个天线端口，各天线端口对应的资源相同。通过下行解调参考信号端口在相同资源上对应的TCI状态的个数确定出传输数据的层到端口的映射关系。

其中，p i，TCIstateij，
Figure PCTCN2021111389-appb-000006
是PDSCH的第i个DMRS端口对应的2个TCI状态中的第j个TCI状态对应的信道部分或者天线端口。其中，t是资源RE索引，x (i)(t)是第i层的数据。公式(2)中的w为下三角矩阵，第i列中的第个

元素到第
Figure PCTCN2021111389-appb-000008
个元素的元素值为1，其余元素的元素值为0，其中，T i可以是第i个DMRS端口对应的TCI状态的个数。例如，当V＝2时，每个DMRS端口对应2个TCI状态，则公式(3)如下所示：
Figure PCTCN2021111389-appb-000009
其中，天线端口p i，TCIstatei1和天线端口p i，TCIstatei2占用的资源相同，即为DMRS端口p i，
Figure PCTCN2021111389-appb-000010
占有的资源，其中，资源包括天线端口对应的参考信号所占用的时频资源、码域资源和序列资源。区别是天线端口p i，TCIstatei1和DMRS端口p i的TCI statei1中的参考信号满足准共址关系，天线端口p i，TCIstatei2和DMRS端口p i的TCI statei2中的参考信号满足准共址关系。

在一个实施例中，每个DMRS端口分别对应不同的2个TCI状态，或者，多个DMRS端口都对应相同的2个TCI状态，即，TCIstatei1＝TCIstatej1，TCIstatei2＝TCIstatej2，公式(2)也改写为如下公式(4)：
Figure PCTCN2021111389-appb-000011
此时天线端口索引根据DMRS端口号和DMRS端口号对应的TCI状态相对索引得到，比如先TCI状态相对索引递增，然后再DMRS端口索引递增.或者先DMRS端口索引递增，然后再TCI状态相对索引递增，此时W中第i列中的第i个元素和第v+i个元素的元素值为1，其余元素的元素值都为0。其中TCI状态的相对索引是TCI状态在同一个DMRS端口对应的多个TCI状态中的相对索引。例如，比如v＝2时，每个DMRS端口对应2个TCI状态，相应的，则公式(5)如下：
Figure PCTCN2021111389-appb-000012
其中，天线端口p i，TCIstatei1和天线端口p i，TCIstatei2占有的资源相同，即为DMRS端口p i，
Figure PCTCN2021111389-appb-000013
占有的资源，其中，资源包括天线端口对应的参考信号所占用的时频资源、码域资源和序列资源。区别是天线端口p i，TCIstatei1和DMRS端口p i的TCI statei1中的参考信号满足准共址关系，天线端口p i，TCIstatei2和DMRS端口p i的TCI statei2中的参考信号满足准共址关系。在一个实施例中，一个DMRS端口对应Y个TCI状态的时候，层到天线端口映射的时候，天线端口的获取中是否引入TCI状态信息，根据所述Y个TCI状态是否对应一个DMRS端口的相同时频资源，如果Y个TCI状态对应所述一个DMRS的相同资源RE上，即DMRS在资源RE上根据Y个TCI状态获取准共址参考信号资源，则层到天线端口的映射采用公式(2)～(5)中的一个，如果Y个TCI状态分别对应一个DMRS的不同资源，即在不同的资源上根据Y个TCI状态中与资源对应的TCI状态获取所述DMRS的准共址参考信号资源，则层到天线端口的映射采用公式(6)：
Figure PCTCN2021111389-appb-000014
其中，[p 0，p 0，...，p v-1]是下行PDSCH的DMRS的端口号，此时天线端口号[p 0，p 0，...，p v-1]的获取参数中不包括DMRS端口对应的TCI状态信息。
