Description

功率确定方法、装置及设备 技术领域
本发明涉及通信技术领域，尤其涉及一种功率确定方法、装置及设备。
背景技术
终端设备在向网络设备发送上行数据之前，终端设备需要先确定上行的实际发送功率，并根据实际发送功率传输上行数据。
在相关技术中，通常先确定终端设备的最大发送功率和期望发送功率，并将终端设备的最大发送功率和与期望发送功率中的最小值确定为初始发送功率。其中，通常根据预设的公式计算最大发送功率，使得终端设备的最大发送功率通常为定值。由于终端设备的最大发送功率为定值，因此，在计算终端设备的实际发送功率时，需要根据终端设备是否支持满功率发送对确定得到的初始发送功率进行处理，以得到实际发送功率。例如，如果在当前传输方案和端口配置下终端设备支持满功率发送，则将初始发送功率确定为实际发送功率；如果在当前传输方案和端口配置下终端设备不支持满功率发送时，则将初始发送功率乘以预设衰减系数，得到实际发送功率。
然而，在终端设备不支持满功率传输时，初始发送功率可能没有达到终端设备在当前传输方案和端口配置下支持的最大发送功率，即，终端设备可以按照初始发送功率发送上行数据，但是，通过上述方法计算得到的实际发送功率小于初始发送功率，使得终端设备的实际发送功率较小，导致上行传输性能较差。
发明内容

所述处理模块用于，根据TRI、发送TPMI或SRI中的至少一个，确定终端设备的物理上行共享信道PUSCH的最大发送功率。
第三方面，本申请实施例提供一种功率确定装置，包括存储器和处理器，所述处理器执行所述存储器中的程序指令，用于实现第一方面所述的功率确定方法。
第四方面，本申请实施例提供一种存储介质，所述存储介质用于存储计算机程序，所述计算机程序被计算机或处理器执行时用于实现第一方面所述的功率确定方法。
第五方面，本申请实施例提供一种计算机程序产品，所述计算机程序产品包括指令，当所述指令 被执行时，使得计算机执行上述第一方面所述的功率确定方法。

本申请实施例提供的功率确定方法、装置及设备，终端设备获取TRI、TPMI或SRI中的至少一个，并根据TRI、TPMI或SRI中的至少一个确定终端设备的PUSCH的最大发送功率。在上述过程中，由于TRI、TPMI或SRI中的至少一个可以反映终端设备是否可以全功率发送，使得通过上述方法确定得到的最大发送功率与终端设备是否支持全功率发送相关，因此，根据该最大发送功率确定终端设备的PUSCH的实际发送功率时，无需进行功率缩减，提高终端设备的实际发送功率，进而提高上行传输性能。

可选的，终端设备可以根据最大发送功率确定终端设备的PUSCH的实际发送功率。实际发送功率是指终端设备的每个非零功率的PUSCH天线端口上的实际发送功率。
可以通过如下方式确定终端设备的PUSCH的实际发送功率：将终端设备PUSCH的最大发送功率与期望发送功率中的最小值确定为实际发送总功率，将实际发送总功率平均分配到每个非零功率的PUSCH天线端口上，得到每个非零功率的PUSCH天线端口上的实际发送功率。这里，实际发送总功率可以采用dBm为单位表示。非零功率的PUSCH天线端口是指实际传输上行数据的天线端口，零功率的PUSCH端口是指不传输上行数据的天线端口，非零功率的PUSCH天线端口与预编码矩阵中的非零端口对应。可以将实际发送总功率的线性值与非零功率的PUSCH天线端口的数量的比值，作为每个非零功率的PUSCH天线端口的实际发送功率。在本申请实施例中，当发送功率的单位为dBm时，发送功率的值可以称为指数值，当发送功率的单位为w(瓦)时，发送功率的值可以称为线行值。
可选的，终端设备的PUSCH的实际发送总功率P PUSCH，b，f，c(i,j,q d,l)可以通过如下公式表示：
Figure PCTCN2019100829-appb-000002
其中，终端设备的PUSCH的最大发送功率为：P CMAX,f,c(i)-k。P CMAX,f,c(i)为预设发送功率，该预设发送功率还可以称为预设的最大发送功率。k为最大发送功率调整值。期望发送功率如下：
Figure PCTCN2019100829-appb-000003
i是一次PUSCH传输的索引，c是指服务小区标识，f是指载波标识，b是指带宽部分Bandwidth Part标识，j是开环功率控制参数索引，μ是子载波间隔配置，l是闭环功率控制进程。P O_PUSCH,b,f,c(j)是指目标功率，α b,f,c(j)是指路损因子，

是在服务小区c载波f的激活BWPb上的PUSCH传输带宽。q d是用于进行路损测量的参考信号的索引，用于得到路损值PL b,f,c(q d)，也是一个开环功率控制参数；f b,f,c(i,l)是闭环功率控制调整因子。
终端设备还可以根据所述最大发送功率确定PUSCH的功率余量，并向网络设备发送功率余量。
例如，假设终端设备上报的功率余量是基于实际传输的PUSCH，则功率余量PH type1,b,f,c(i,j,q d,l)可以如下所示：
Figure PCTCN2019100829-appb-000005
其中，P M,f,c(i)为所述PUSCH的最大发送功率，根据调度所述PUSCH的DCI中的TRI、TPMI和SRI中的至少一个确定，即，P M,f,c(i)＝P CMAX,f,c(i)-k。其他参数根据所述PUSCH的功率控制参数得到，与所述期望发送功率计算方法相同，此处不再赘述。
例如，假设终端设备上报的功率余量是基于虚拟的PUSCH传输，则功率余量PH type1,b,f,c(i,j,q d,l)可以如下所示：
P M,f,c(i)-{P O_PUSCH,b,f,c(j)+α b,f,c(j)·PL b,f,c(q d)+f b,f,c(i,l)}
其中，P M,f,c(i)为根据预设的SRI、预设的TPMI和预设的TRI中的至少一个得到的最大发送功率。例如，预设的TRI可以指示单层传输或者满秩传输；预设的TPMI可以为所有端口都为非零端口的TPMI；预设的SRI指示的SRI取值为0。
例如，假设预设发送功率为23dBm，假设期望发送功率为20dBm，则在终端设备不支持满功率发送时，按照现有技术的方法，确定得到的终端设备的实际发送总功率为：20dBm乘以小于1的缩减系数，则得到的实际发送功率小于20dBm，例如，实际发送功率可能为17dBm。按照本申请的方法，假设确定得到的最大发送功率调整值为3dBm，则终端设备的最大发送功率为23-3＝20dBm，确定得到的实际发送功率20dBm(不需要进一步进行功率缩减)。由上可知，通过本申请所示的方法，可以提高终端设备的实际传输功率。
本申请所示的支持满功率传输是指，终端设备可以采用预设发送功率P CMAX,f,c(i)发送上行数据。
本申请实施例提供的功率确定方法，终端设备获取TRI、TPMI或SRI中的至少一个，并根据TRI、TPMI或SRI中的至少一个确定终端设备的PUSCH的最大发送功率。在上述过程中，由于TRI、TPMI或SRI中的至少一个可以反映终端设备是否可以全功率发送，使得通过上述方法确定得到的最大发送功率与终端设备是否支持全功率发送相关，因此，根据该最大发送功率确定终端设备的PUSCH的实际发送功率时，无需进行功率缩减，提高终端设备的实际发送功率，进而提高上行传输性能。
在上述任意一个实施例的基础上，下面，结合图3对功率确定方法进行说明。

例如，假设预设发送功率为P CMAX,f,c(i)，则最大发送功率为P CMAX,f,c(i)-k。
需要说明的是，S303-S304的执行过程可以参见S301的执行过程，此处不再进行赘述。
S305、终端设备将最大发送功率与期望发送功率中的最小值确定为实际发送总功率。

其中

在图3所示的实施例中，终端设备可以在接收到的DCI中获取TRI、TPMI或SRI中的至少一个，根据TRI、TPMI或SRI中的至少一个，确定终端设备的PUSCH的最大发送功率。在上述过程中，由于TRI、TPMI或SRI中的至少一个可以反映终端设备是否可以全功率发送，使得通过上述方法确定得到的最大发送功率与终端设备是否支持全功率发送相关，因此，根据该最大发送功率确定终端设备的PUSCH的实际发送功率时，无需进行功率缩减，提高终端设备的实际发送功率，进而提高上行传输性能。
在上述任意实施例的基础上，下面，介绍根据TRI、TPMI或SRI中的至少一个确定最大发送功率调整值的方式。
第一种方式：根据SRI，确定最大发送功率调整值。
在SRI指示的探测参考信号SRS资源包括的SRS端口的数量为1时，确定终端设备的最大发送功率调整值为0(dB)。
在该种方式中，终端设备根据SRI即可确定得到最大发送功率调整值，使得终端设备可以快速确定得到最大发送功率调整值。在最大功率调整值为0dB时，终端设备可以满功率进行上行数据的发送，不需要进行功率缩减，使得上行发送功率较高，使得上行覆盖范围较大，进而使得上行传输性能较高。
第二种方式：根据TRI，确定最大发送功率调整值。
如果所述TRI指示的秩等于为所述终端设备配置的PUSCH天线端口的数量，所述终端设备的最大发送功率调整值为0。或者，在所述TRI指示的秩等于所述SRI指示的SRS资源包括的SRS端口的数量，所述终端设备的最大发送功率调整值为0。
在一种实施方式中，如果所述TRI指示的秩小于为所述终端设备配置的PUSCH天线端口的数量，或者小于所述SRI指示的SRS资源包括的SRS端口的数量，则可以确定所述终端设备的最大发送功率调整值大于0。此时，也可以根据其他参数确定最大发送功率调整值，本发明不限于此。
第三种方式：根据TRI和TPMI，确定最大发送功率调整值。
在一种实施方式中，如果所述TRI指示的秩等于为所述终端设备配置的PUSCH天线端口的数量， 或者，TPMI或者TPMI指示的预编码矩阵属于支持满功率发送的预编码矩阵信息集合时，所述终端设备的最大发送功率调整值为0。如果所述TRI指示的秩小于为所述终端设备配置的PUSCH天线端口的数量，且TPMI或者TPMI指示的预编码矩阵不属于支持满功率发送的预编码矩阵信息集合时，则可以确定所述终端设备的最大发送功率调整值大于0。
在另一种实施方式中，如果所述TRI指示的秩等于所述SRI指示的SRS资源包括的SRS端口的数量，或者，TPMI或者TPMI指示的预编码矩阵属于支持满功率发送的预编码矩阵信息集合时，所述终端设备的最大发送功率调整值为0。如果所述TRI指示的秩小于所述SRI指示的SRS资源包括的SRS端口的数量，且TPMI或者TPMI指示的预编码矩阵不属于支持满功率发送的预编码矩阵信息集合时，则可以确定所述终端设备的最大发送功率调整值大于0。
第四种方式：根据SRI和TRI，确定最大发送功率调整值。
在SRI指示的SRS资源包括的SRS端口的数量大于1，且TRI指示的秩等于为终端设备配置的PUSCH天线端口的数量时，确定终端设备的最大发送功率调整值为0(dB)。
或者，
在SRI指示的SRS资源包括的SRS端口的数量大于1，且TRI指示的秩等于所述SRS端口的数量时，确定终端设备的最大发送功率调整值为0(dB)。
其中，TRI指示的秩等于为终端设备配置的PUSCH天线端口的数量、以及TRI指示的秩等于SRI指示的SRS资源包括的SRS端口的数量分别是指，终端设备可以满秩传输，即，终端设备可以满功率传输。
在该种方式中，终端设备在获取得到SRI和TRI之后，可以先判断SRI指示的SRS资源包括的SRS端口的数量是否为1，若否，再根据TRI指示的秩判断终端设备是否可以满功率传输，在确定终端设备可以满功率传输时，确定终端设备的最大发送功率调整值为0dB。这样，终端设备根据SRI和TRI即可确定得到最大发送功率调整值，使得终端设备可以快速确定得到最大发送功率调整值。在最大功率调整值为0dB时，终端设备可以满功率进行上行数据的发送，不需要进行功率缩减，使得上行发送功率较高，使得上行覆盖范围较大，进而使得上行传输性能较高。
第五种方式：根据SRI和TPMI，确定最大发送功率调整值。
在SRI指示的SRS资源包括的SRS端口的数量大于1，且TPMI或者TPMI指示的预编码矩阵属于支持满功率发送的预编码矩阵信息集合时，确定终端设备的最大发送功率调整值为0dB。
支持满功率发送的预编码矩阵信息集合包括至少一个支持满功率发送的TPMI，或者至少一个支持满功率发送的预编码矩阵。支持满功率发送的TPMI是指，通过该TPMI指示预编码矩阵对上行的数字信号进行预编码之后，可以对上行数字信号进行满功率传输。支持满功率发送的预编码矩阵是指，通过该预编码矩阵对上行的数字信号进行预编码之后，可以对上行数字信号进行满功率传输。
所述支持满功率发送的预编码矩阵信息集合可以为终端设备预先上报给网络设备的，例如，终端设备可以根据每个射频通道支持的最大发送功率确定支持满功率发送的TPMI或者预编码矩阵。例如，如果终端设备的所有射频通道都支持满功率发送，则终端设备可以确定预编码矩阵信息集合中包括所有支持的TPMI或者所有TPMI可能指示的预编码矩阵。终端设备可以通过UE能力信息向网络设备发送所述预编码矩阵信息集合。以下描述中的预编码矩阵信息集合均指所述支持满功率发送的预编码矩阵信息集合。
例如，终端设备可以在UE能力信息中通过位图(bitmap)的方式指示哪些TPMI可以支持满功率发送，每个比特对应一个TPMI，当TPMI支持满功率发送时，则该TPMI对应的比特为1，当TPMI 不支持满功率发送时，则该TPMI对应的比特为0。这里的TPMI可以包含DCI中可能指示的部分或全部TPMI。基于该bitmap就可以确定支持满功率发送的TPMI集合。
例如，终端设备可以在UE能力信息中通过bitmap的方式指示哪些预编码矩阵可以支持满功率发送，每个比特对应一个预编码矩阵，当预编码矩阵支持满功率发送时，则该预编码矩阵对应的比特为1，当预编码矩阵不支持满功率发送时，则该预编码矩阵对应的比特为0。这里的预编码矩阵包含TPMI可能指示的预编码矩阵中的部分或全部预编码矩阵。基于该bitmap就可以确定支持满功率发送的预编码矩阵集合。
可选的，预编码矩阵信息集合中可以包括终端设备支持的多个不同端口数(或者传输层数，或者秩)对应的预编码矩阵信息。例如，假设终端设备当前可以支持最多4个端口的PUSCH传输，则预编码矩阵信息集合中可以包括2端口对应的预编码矩阵信息(TPMI或者预编码矩阵)和4端口对应的预编码矩阵信息(TPMI或者预编码矩阵)。
在该种方式中，终端设备在获取得到SRI和TPMI之后，可以先判断SRI指示的SRS资源包括的SRS端口的数量是否为1，若否，再根据TPMI判断终端设备是否可以满功率传输，在确定终端设备支持满功率传输时，确定终端设备的最大发送功率调整值为0dB。这样，终端设备根据SRI和TPMI即可确定得到最大发送功率调整值，使得终端设备可以快速确定得到最大发送功率调整值。在最大功率调整值为0时，终端设备可以满功率进行上行数据的发送，不需要进行功率缩减，使得上行发送功率较高，使得上行覆盖范围较大，进而使得上行传输性能较高。
第六种方式：根据SRI和TPMI，确定最大发送功率调整值。
在SRI指示的SRS资源包括的SRS端口的数量大于1，TPMI或TPMI指示的预编码矩阵不属于支持满功率发送的预编码矩阵信息集合时，根据TPMI指示的预编码矩阵中的非零端口的数量和第一端口数量，确定终端设备的PUSCH的最大发送功率调整值。其中，第一端口数量为：SRI指示的SRS资源包含的SRS端口的数量，或TPMI指示的预编码矩阵的端口的数量，或终端设备支持的最大上行传输端口的数量，或终端设备在一个SRS资源内支持的最大SRS端口数量。
需要说明的是，该种方式中的预编码矩阵信息集合可以参见第五种方式中的描述，此处不再进行赘述。
可选的，可以根据如下公式确定功率调整值k：k＝10*log 2(M/N)，其中，N为TPMI指示的预编码矩阵中的非零端口的数量，M为第一端口数量。
在该种方式中，终端设备在获取得到SRI和TPMI之后，可以先判断SRI指示的SRS资源包括的SRS端口的数量是否为1，若否，再判断TPMI或TPMI指示的预编码矩阵是否属于支持满功率发送的预编码矩阵信息集合，若否，则根据TPMI指示的预编码矩阵中的非零端口的数量和第一端口数量确定功率调整值，进而实现对最大发送功率进行衰减，这样，不但可以避免计算得到的终端设备的实际发送功率超过终端设备的最大发送功率，还可以避免对终端设备的实际发送功率进行不必要的衰减，提高终端设备的实际发送功率，进而提高上行传输性能。
第七种方式：根据SRI，确定最大发送功率调整值。
在SRI指示的SRS资源包括的SRS端口的数量大于1时，根据SRS端口的数量和第一对应关系，确定终端设备的最大发送功率调整值，第一对应关系为SRS端口的数量与最大发送功率调整值之间的对应关系。
可以预先设置第一对应关系，当SRS端口的数量不同时，对应的最大发送功率调整值也不同。其中，所述最大发送功率调整值不一定是通过所述SRS端口直接确定的，而是可以在不同的SRS端口数 量下，采用不同的公式来得到所述最大发送功率调整值。
例如，第一对应关系可以为：在SRS端口的数量为2时，最大发送功率调整值为k＝10*log 2(M/N)，其中，N为TPMI指示的预编码矩阵中的非零端口的数量，M为所述SRS端口的数量。在SRS端口的数量为4时，最大发送功率调整值为
Figure PCTCN2019100829-appb-000010
在该种方式中，在SRI指示的SRS资源包括的SRS端口的数量大于1时，根据SRS端口的数量和第一对应关系可以快速确定得到确定终端设备的最大发送功率调整值。
第八种方式：根据SRI和TPMI，确定最大发送功率调整值。
在SRI指示的SRS资源包括的SRS端口的数量大于1，且TPMI或TPMI指示的预编码矩阵不属于支持满功率发送的预编码矩阵信息集合时，根据SRS端口的数量和第一对应关系，确定终端设备的最大发送功率调整值，第一对应关系为SRS端口的数量与最大发送功率调整值之间的对应关系。
例如，第一对应关系可以为：在SRS端口的数量为2时，最大发送功率调整值为3dBm。或者，第一对应关系可以为：在SRS端口的数量为4时，若TPMI指示的预编码矩阵的端口中存在一半端口为非零端口，则功率调整值为3dBm，若TPMI指示的预编码矩阵的端口中的一个端口为非零端口，则功率调整值为6dBm。
在该种方式中，终端设备在获取得到SRI和TPMI之后，可以先判断SRI指示的SRS资源包括的SRS端口的数量是否为1，若否，再判断TPMI或TPMI指示的预编码矩阵是否属于支持满功率发送的预编码矩阵信息集合，若否，则根据SRS端口的数量和第一对应关系确定终端设备的最大发送功率调整值，进而实现对最大发送功率进行衰减，这样，不但可以避免计算得到的终端设备的实际发送功率超过终端设备的最大发送功率，还可以避免对终端设备的实际发送功率进行不必要的衰减，提高终端设备的实际发送功率，进而提高上行传输性能。
第九种方式：根据TPMI，确定最大发送功率调整值。
根据TPMI和第二对应关系，确定终端设备的最大发送功率调整值，第二对应关系为TPMI与最大发送功率调整值之间的对应关系，或者，第二对应关系为TPMI指示的预编码矩阵与最大发送功率调整值之间的对应关系；其中，第二对应关系为根据支持满功率发送的预编码矩阵信息集合确定得到的。
可选的，可以是在TPMI或TPMI指示的预编码矩阵不属于支持满功率发送的预编码矩阵信息集合时，根据TPMI和第二对应关系，确定终端设备的PUSCH的最大发送功率调整值。或者，可以是在SRI指示的SRS资源包括的SRS端口的数量大于1，且TPMI或TPMI指示的预编码矩阵不属于支持满功率发送的预编码矩阵信息集合时，根据TPMI和第二对应关系，确定终端设备的PUSCH的最大发送功率调整值。
终端设备可以预先根据预编码矩阵信息集合对应的预编码矩阵中的非零端口的数量，确定第二对应关系；其中，预编码矩阵信息集合对应的预编码矩阵包括：预编码矩阵信息集合中包括的预编码矩阵，或者预编码矩阵信息集合包含的TPMI指示的预编码矩阵。根据不同的预编码矩阵信息集合确定得到的第二对应关系不同。不同的预编码矩阵信息集合是指预编码矩阵信息集合中包括的TPMI不同，或者包括的预编码矩阵不同。
下面以预编码矩阵信息集合包含至少一个预编码矩阵为例，介绍几种不同预编码矩阵信息集合对应的第二对应关系，可以包括如下情况(在以下情况中，预编码矩阵指所述TPMI可能指示的预编码矩阵)：
情况1、在所述预编码矩阵信息集合包含的任一预编码矩阵的全部端口均为非零端口，且当前TPMI指示的预编码矩阵不属于支持满功率发送的所述预编码矩阵信息集合时，第二对应关系为： k＝10*log 2(T/N)。
其中，k为最大发送功率调整值，N为当前TPMI指示的预编码矩阵中的非零端口的数量，T为当前TPMI指示的预编码矩阵的端口的数量。
例如，假设当前TPMI指示的预编码矩阵为：
Figure PCTCN2019100829-appb-000011
该预编码矩阵的非零端口的数量N＝2，端口数量T＝4，则根据当前TPMI和第二对应关系确定得到的最大发送功率调整值为：

情况2、在所述预编码矩阵信息集合包含第一预编码矩阵集合中的全部预编码矩阵，且当前TPMI指示的预编码矩阵不属于支持满功率发送的所述预编码矩阵信息集合时，第二对应关系为：k＝3dB，或者，k＝10*log 2(T/N)-3dB。
其中，所述第一预编码矩阵集合包含不同TPMI可能指示的预编码矩阵中一半端口为非零端口的预编码矩阵，例如

等。N为当前TPMI指示的预编码矩阵中的非零端口的数量，T为当前TPMI指示的预编码矩阵的端口的数量。
例如，假设当前TPMI指示的预编码矩阵为：
Figure PCTCN2019100829-appb-000017
该预编码矩阵的非零端口的数量N＝1，端口数量T＝4，则根据当前TPMI和第二对应关系确定得到的最大发送功率调整值为3dB，或者，

情况3、在所述预编码矩阵信息集合包含所述第一预编码矩阵集合中的部分预编码矩阵，且当前TPMI指示的预编码矩阵不属于支持满功率发送的所述预编码矩阵信息集合时，则对于部分TPMI，所述第二对应关系为：k＝3dB或者k＝10*log 2(T/N)-3dB；对于另一部分TPMI，所述第二对应关系为：k＝6dB或者k＝10*log 2(T/N)。
其中，N为当前TPMI指示的预编码矩阵中的非零端口的数量，T为当前TPMI指示的预编码矩阵的端口的数量。
例如，假设所述预编码矩阵信息集合包含
Figure PCTCN2019100829-appb-000019
且当前TPMI指示的预编码矩阵(不包含在所 述预编码矩阵信息集合中)为：
Figure PCTCN2019100829-appb-000020
该预编码矩阵的非零端口的数量N＝2，端口数量T＝4，则根据TPMI和第二对应关系确定得到的最大发送功率调整值为
Figure PCTCN2019100829-appb-000021
如果当前TPMI指示的预编码矩阵(不包含在所述预编码矩阵信息集合中)为：
Figure PCTCN2019100829-appb-000022
该预编码矩阵的非零端口的数量N＝1，端口数量T＝4，则根据TPMI和第二对应关系确定得到的最大发送功率调整值为
Figure PCTCN2019100829-appb-000023
情况5、所述预编码矩阵信息集合包含第二预编码矩阵集合中的一部分预编码矩阵，且当前TPMI指示的预编码矩阵不属于支持满功率发送的所述预编码矩阵信息集合时，第二对应关系为：k＝3dB，或者，k＝10*log 2(T/N)-3dB。
其中，所述第二预编码矩阵集合包含不同TPMI可能指示的预编码矩阵中只有一个端口为非零端口的预编码矩阵，例如

则该预编码矩阵的非零端口的数量N＝1，端口数量T＝4，则根据TPMI和第二对应关系确定得到的最大发送功率调整值为
Figure PCTCN2019100829-appb-000027
以上方法同样适用于所述预编码矩阵信息集合包含至少一个TPMI的情况，具体方法与上述方法类似，这里不再详述。
在该种方式中，终端设备在获取得到SRI和TPMI之后，可以先判断SRI指示的SRS资源的端口数是否为1，若否，再判断TPMI或TPMI指示的预编码矩阵是否属于支持满功率发送的预编码矩阵信息集合，若否，则根据SRS端口的数量和第二对应关系确定终端设备的最大发送功率调整值。由于预编码矩阵信息集合实际反映了终端不同的射频配置(即每个射频通道能够支持的最大发送功率)，通过上述方法可以根据预编码矩阵信息集合对应的终端每个射频通道的最大功率，确定每个TPMI对应的最大功率调整值，从而终端设备在采用相应TPMI对应的预编码矩阵进行上行传输时，能够达到每个 射频通道的最大功率。进而提高上行传输性能。
需要说明的是，上述第一种方式至第九种方式可以单独存在，也可以相互结合。
下面，结合图4，以第一种方式、第四种方式、第五种方式和第六种方式的结合为例，对确定最大发送功率调整值的过程进行说明。
图4为本申请实施例提供的一种确定最大发送功率调整值方法的流程示意图。在图4所示的实施例中，根据SRI、TRI和TPMI确定终端设备的最大发送功率调整值。请参见图4，该方法可以包括：

在图4所示的实施例中，终端设备在SRI、TRI和TPMI之后，终端设备依次判断SRI、TRI和TPMI是否满足终端设备满功率传输的条件，若其中一个满足终端设备满功率传输的条件，则确定最大发送功率调整值为0，进而终端设备可以满功率进行上行数据的发送，不需要进行功率缩减，使得上行发送功率较高，使得上行覆盖范围较大，进而使得上行传输性能较高。在SRI、TRI和TPMI均不满足终端设备满功率传输的条件时，则终端设备根据SRS端口的数量和第一对应关系，确定终端设备的最大发送功率调整值，进而实现对最大发送功率进行衰减，这样，不但可以避免终端设备的实际发送功率超过终端设备的最大发送功率，还可以避免对终端设备的实际发送功率进行不必要的衰减，提高终端设备的实际发送功率，进而提高上行传输性能。
下面，结合图5，以第一种方式、第五种方式和第九种方式的结合为例，对确定最大发送功率调整值的过程进行说明。
图5为本申请实施例提供的另一种确定最大发送功率调整值方法的流程示意图。在图4所示的实施例中，根据SRI和TPMI确定终端设备的最大发送功率调整值。请参见图5，该方法可以包括：

在实际应用过程中，终端设备在确定得到第二对应关系之后，可以在预设存储空间存储第二对应关系，相应的，当终端设备需要使用第二对应关系时，在预设存储空间获取第二对应关系即可。换句话说，无需在每次确定最大发送功率调整值之前执行S501-S503。

需要说明的是，S508的执行过程可以参见第九种方式，此处不再进行赘述。
S509、终端设备确定终端设备的最大发送功率调整值为0dB。
在图5所示的实施例中，终端设备可以先确定预编码矩阵信息集合，以及根据预编码矩阵信息集合确定第二对应关系。终端设备在SRI和TPMI之后，终端设备依次判断SRI和TPMI是否满足终端设备满功率传输的条件，若其中一个满足终端设备满功率传输的条件，则确定最大发送功率调整值为0，进而终端设备可以满功率进行上行数据的发送，不需要进行功率缩减，使得上行发送功率较高，使得上行覆盖范围较大，进而使得上行传输性能较高。在SRI和TPMI均不满足终端设备满功率传输的条件时，则终端设备根据TPMI和第二对应关系，确定终端设备的最大发送功率调整值，由于预编码矩阵信息集合实际反映了终端不同的射频配置(即每个射频通道能够支持的最大发送功率)，通过上述方法可以根据预编码矩阵信息集合对应的终端每个射频通道的最大功率，确定每个TPMI对应的最大功率调整值，从而终端设备在采用相应TPMI对应的预编码矩阵进行上行传输时，能够达到每个射频通道的最大功率，进而提高上行传输性能。
需要说明的是，图4和图5只是以示例的形式示意对上述九种方式的结合，当然，在实际应用过程中，还可以通过其它方式对上述九种方式中的任意多种方式进行结合，本申请实施例对此不作具体限定。
