可选地，在一些实施例中，网络设备可以通过第一高层信令为所述终端设备预配置多个SRI信息对应的开环功率控制参数或下行参考信号的索引，其中，所述多个SRI信息包括所述第一SRI信息。从而，所述终端设备可以根据所述第一SRI信息的取值确定对应的开环功率控制参数，然后基于这些参数得到对应的发送功率。所述终端设备还可以根据所述第一SRI信息的取值确定对应的目标下行参考信号的索引，然后基于该索引指示的目标下行参考信号进行下行路损测量，从而得到用于功率控制的路损值。也就是说，所述网络设备可以给终端设备预配置多个SRI信息和开环功率控制参数或者下行参考信号的索引的对应关系，从而终端设备可以根据当前的SRI信息的取值，结合该对应关系，确定该SRI信息对应的开环功率控制参数或者下行参考信号的索引。
例如，所述SRI指示域可以为2比特指示域，作为示例而非限定，该2比特指示域取值为00对应开环功率控制参数1和下行参考信号索引1，取值为01对应开环功率控制参数2和下行参考信号索引2，取值为10对应开环功率控制参数2和下行参考信号索引1，取值为11对应开环功率控制参数1和下行参考信号索引2。从而，所述终端设备可以根据第一SRI信息的取值即可获知对应的开环功率控制参数或者下行参考信号的索引，例如，若所述第一SRI信息的取值为10，则所述终端设备可以确定对应开环功率控制参数2和下行参考信号索引1，进一步地，可以根据开环功率控制参数2和下行参考信号索引1进行功率控制。
可选地，在一些实施例中，网络设备可以直接配置与所述第一SRI信息关联的开环功率控制参数或者下行参考信号的索引，此情况下，第一开环功率控制参数发生重配置，可以是终端设备检测到网络设备通过第一高层信令重新配置与所述第一SRI信息关联的开环功率控制参数，例如，第一SRI信息原来关联开环功率控制参数1，网络设备重新 配置第一SRI消息关联开环功率控制参数2，此时，所述终端设备可以将所述第一SRI信息关联的第一闭环调整因子置零，进一步地，所述终端设备可以根据置零的所述第一闭环调整因子，确定PUSCH的发送功率，从而能够提升功率控制的准确度。
可选地，在一些实施例中，网络设备可以预先配置开环功率控制参数(例如，P O_PUSCH,f,c(j)或α f,c(j))对应的索引(例如，公式中的j)，即开环功率控制参数与索引的对应关系(记为第一对应关系)，例如，网络设备可以配置不同的j的取值对应的P O_PUSCH,f,c(j)或α f,c(j)，进一步地，所述网络设备还可以配置开环功率控制参数的索引和SRI信息的对应关系(记为第二对应关系)，这样，所述终端设备可以根据所述第一SRI信息，以及所述第二对应关系，确定开环功率控制参数的索引，进一步地，可以根据该开环功率控制参数的索引和第一对应关系，确定该开环功率控制参数的索引对应的开环功率控制参数。此情况下，第一SRI信息关联的第一开环功率控制参数发生重配置，可以是所述终端设备检测到网络设备通过第一高层信令重新配置所述第一SRI对应的开环功率控制参数的索引(即重新配置所述第二对应关系)，或者，重新配置开环功率控制参数索引对应的开环功率控制参数(即重新配置所述第一对应关系)。
类似地，网络设备也可以通过第一高层信令给所述终端设备预先配置多个下行参考信号和对应的下行参考信号的索引(例如，q d)的对应关系(记为第三对应关系)，进一步地，所述网络设备可以配置所述第一SRI信息关联的目标下行参考信号的索引(记为第四对应关系)，从而，终端设备可以根据所述第一SRI信息，以及所述第四对应关系，确定目标下行参考信号的索引；再结合所述目标下行信号的索引，以及该第三对应关系，确定与所述第一SRI信息关联的目标下行参考信号。此情况下，所述第一SRI信息关联的第一下行参考信号发生重配置，可以是网络设备通过第一高层信令重新配置与所述第一SRI信息关联的下行参考信号的索引(即重新配置第四对应关系)，或者，网络设备重新配置所述下行参考信号索引所对应的下行参考信号(可以理解为所述第三对应关系发生变化)。例如，网络设备原来配置第一SRI信息与下行参考信号索引0相关联，网络设备重新配置第一SRI信息与下行参考信号索引1关联；或者，网络设备原来配置下行参考信号索引0与CSI-RS0关联，网络设备重新配置下行参考信号索引0与CSI-RS1关联。
可选地，在一些实施例中，所述方法200还可以包括：
所述终端设备接收网络设备发送的第二高层信令，所述第二高层信令用于配置所述终端设备的每个带宽部分BWP上多个SRI信息对应的开环功率控制参数或下行参考信号的索引；

即所述网络设备可以通过第二高层信令配置每个带宽部分(Bandwidth Part，BWP)上多个SRI信息对应的开环功率控制参数或下行参考信号的索引(记为第五对应关系)，也就是说，每个BWP上可以有一个第五对应关系，从而，所述终端设备可以传输PUSCH的BWP上的该第五对应关系，确定第一信息关联的第一开环功率控制参数或者与第一SRI信息关联的第一下行参考信号。
可选地，所述第一高层信令和所述第二高层信令可以为同一高层信令，或不同的高层信令，本申请实施例对此不作限定。
应理解，在本申请实施例中，在第一SRI信息对应的第一开环功率控制参数或第一下行参考信号发生重配置时，若所述终端设备依然基于重配置前获得的第一闭环调整因子对重配置后的发送功率进行调整，可能会降低功率控制的准确度，此情况下，所述终端设备可以将所述第一SRI信息对应的第一闭环调整因子置零，重新进行发送功率的闭环累加调整，从而可以根据置零的所述第一闭环调整因子进行功率控制，从而能够提高功率控制的准确度。
需要说明的是，在本申请实施例中，所述第一SRI信息对应的第一闭环调整因子可以对应于f c(i,l)，将与所述第一SRI信息关联的第一闭环调整因子置零，可以包括将所述第一闭环调整因子的历史值置零，例如，将f f,c(i-1,l)置零，或者将所述第一闭环调整因子的当前值置零，例如，将f f,c(i,l)置零。
应理解，在本申请实施例中，在第一SRI信息关联的功率控制控制参数或下行参考信号时发生重配置，所述终端设备只重配置所述第一SRI信息关联的第一闭环调整因子，即只将所述第一SRI信息关联的第一闭环调整因子置零，而不需要调整其他SRI信息关联的闭环调整因子，例如，不需要置零第二SRI信息关联的第二闭环调整因子。
可选地，在本申请实施例中，所述方法200还可以包括：
所述终端设备根据与所述第一SRI信息关联的闭环功率控制进程，确定所述闭环控制进程中的所述第一闭环调整因子。
具体地，网络设备还可以预先配置与所述第一SRI信息关联的闭环功率控制进程的索引(例如，公式中的l)的取值，从而，所述终端设备可以根据该闭环功率控制进程的索引，确定对应的闭环调整因子(例如，公式中的f f,c(i,l))的值，进一步地，可以将其作为与所述第一SRI指示关联的第一闭环调整因子。当第一SRI信息关联的开环功率控制参数或下行参考信号发生重配置时，所述终端设备可以对第一闭环调整因子进行重置， 例如，可以将与所述第一SRI信息关联的第一闭环调整因子的历史值(例如，f f,c(i-1,l))或当前值(例如f f,c(i,l))置零。
特别地，在本申请实施例中，S210可以具体包括：
所述终端设备在所述PUSCH的闭环功率控制开启了累加模式时，将所述第一闭环调整因子置零。
应理解，在本申请实施例中，累加模式可以是针对所有的闭环功率控制进程的，此情况下，所述终端设备可以在与所述第一SRI信息关联的开环功率控制参数或下行参考信号发生重配置，并且闭环功率控制开启了累加模式时，将所述第一SRI信息对应的第一闭环调整因子置零；或者，所述网络设备也可以为每个闭环功率控制进程分别配置对应的累加模式，此情况下，所述终端设备可以在与所述第一SRI信息关联的开环功率控制参数或下行参考信号发生重配置，并且与所述第一SRI信息对应的闭环功率控制进程开启了累加模式时，将所述第一SRI信息对应的第一闭环调整因子置零。
还应理解，具体实现时，所述终端设备还可以在传输所述PUSCH的BWP上开启了闭环功率控制的累加模式时，将所述第一闭环调整因子置零。
可选地，在一些实施例中，所述终端设备可以根据置零后的所述第一功率调整因子，结合前文所述的公式计算PUSCH的发送功率，具体的，可以将所述第一闭环调整因子加到根据开环功率控制参数获得的发送功率上，从而获得所述PUSCH的发送功率，这里不再赘述。
可选地，在一些实施例中，S220可以具体包括：
所述终端设备根据置零的所述第一闭环调整因子，以及最近接收到的发送功率控制TPC命令，确定更新的所述第一闭环调整因子；
所述终端设备根据更新的所述第一闭环调整因子，确定所述PUSCH的发送功率。
具体的，终端设备根据置零后的所述第一闭环调整因子，以及最近接收到的发送功率控制(Transmit Power Control，TPC)命令，确定更新的第一闭环调整因子，进一步地，所述终端设备可以根据更新的所述第一闭环调整因子，确定所述PUSCH的发送功率。此时，开启累加方式的闭环功率控制的第一闭环调整因子f f,c(i,l)可以表示为f f,c(i,l)＝δ PUSCH,f,c(i-K PUSCH,l)，其中，δ PUSCH,f,c(i-K PUSCH,l)为TPC所指示的调整值，即终端设备直接将之前的第一闭环调整因子置零，即f f,c(i-1,l)＝0。
应理解，在本申请实施例中，所述TPC命令可以通过下行DCI指示给终端设备，例如，可以通过调度所述PUSCH的DCI中的TPC指示域指示给所述终端设备，也就是说，所述终端设备可以通过DCI中的TPC指示域获知网络设备配置的闭环功率的调整值，即 δ PUSCH,f,c(i-K PUSCH,l)。
可选地，在一些实施例中，所述方法200还可以包括：
所述终端设备根据所述确定的所述发送功率发送所述PUSCH。
即所述终端设备确定的所述发送功率可以用于发送所述PUSCH，可选地，所述发送功率也可以不用于发送PUSCH，例如，所述终端设备可以根据确定的所述发送功率计算当前PUSCH的功率余量上报(Power Headroom Report，PHR)，然后将PHR上报给网络设备，或者也可以根据确定的所述发送功率计算其他上行信号的发送功率。例如，设备终端可以将确定的所述发送功率加上一定的偏移值得到的功率值确定为SRS的发送功率等，本申请实施例并不限定所述发送功率的应用场景。
