图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
在NR系统中，终端可以有多个Panel用于上行传输，一个panel包含一组物理天线，每个panel可以有独立的射频通道。终端可以同时在多个panel上传输数据，但由于不同panel对应的信道条件是不同的，不同的panel需要根据各自的信道信息采用不同的传输参数，例如发送功率。为了得到这些传输参数，需要为不同的panel配置不同的SRS资源，例如一个panel可以对应一个SRS资源集合，网络侧可以通过SRI资源指示(SRS Resource Indicator)来指示一个SRS资源集合。终端可以根据SRI或SRI指示的SRS资源来得到对应上行传输的功率控制参数，从而得到对应上行数据的发送功率。
目前物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的发送功率可以通过如下公式计算：
Figure PCTCN2018071394-appb-000001
其中，i是一次PUSCH传输的索引，j是开环功率控制参数索引，k是用于路损估计的参考信号(Reference Signal，RS)资源的索引。M PUSCH,c(i)为PUSCH所占的(Resource Block，RB)数目；P CMAX,c(i)为终端设备配置的在服务小区c上子帧i的最大发送功率；P O_PUSCH,c(j)和α c(j)是开环功率控制参数， 为终端设备通过高层信令确定的值；PL c为终端设备测量得到的服务小区c到该终端设备的路径损耗值；Δ TF,c(i)为终端设备根据该PUSCH发送的上行数据比特数和该PUSCH中包括的资源单元的个数的比值确定的值；f c(i,l)是闭环功率控制调整因子，为终端设备根据对该PUSCH的功率调整命令确定的值。
图2示出了本申请实施例的功率控制的方法100的示意性框图。如图2所示，该方法100包括：
S110，终端设备接收网络设备发送的用于调度物理上行共享信道PUSCH的下行控制信息DCI，该DCI包括第一探测参考信号资源指示SRI；
S120，该终端设备根据该DCI，确定与该第一SRI对应的上行功率控制参数的值；
S130，该终端设备根据该与该第一SRI对应的上行功率控制参数的值，确定该PUSCH承载的与该第一SRI对应的第一上行数据的实际发送功率。
可选地，该下行控制信息(Downlink Control Information，DCI)还可以包括第二SRI，该第一SRI和该第二SRI分别对应独立的上行功率控制参数的值。
具体地，网络设备可以预先为终端设备配置该第一SRI和该第二SRI各自对应的上行功率控制参数的取值，例如，网络设备可以预先配置SRI与上行功率控制参数的值的对应关系，网络设备可以在用于调度PUSCH的DCI中携带该第一SRI和该第二SRI，从而使得终端设备能够根据该DCI确定与每个SRI对应的上行功率控制参数的取值，进而可以确定每个SRI对应的上行数据的实际发送功率。例如，基于上述公式，网络设备可以预先通过高层信令配置每个SRI对应的{j，k，l}的取值，不同取值可以得到不同的上行功率控制参数的取值，因此，每个SRI可以对应一组上行功率控制参数的取值。
因此，本申请实施例的功率控制的方法，有利于达到更高的频谱效率。
可选地，在该终端设备接收该DCI之前，该方法还包括：该终端设备接收该网络设备发送的第一配置信息，该第一配置信息用于指示该第一SRI的取值与上行功率控制参数的值的对应关系；该终端设备根据该DCI，确定与该第一SRI对应的上行功率控制参数的值，包括：该终端设备根据该DCI中包括的该第一SRI的取值，以及该对应关系，确定与该第一SRI对应的上行功率控制参数的值。
可选地，在该终端设备接收网络设备发送的该DCI之前，该方法还包括：该终端设备接收该网络设备发送的第二配置信息，该第二配置信息用于指示该第二SRI的取值对应的上行功率控制参数的值，其中，该第二SRI的取值对应的上行功率控制参数的值与该第一SRI的取值对应的上行功率控制参数的值由该网络设备独立配置。
也就是说，网络设备可以预先为终端设备配置SRI的取值与上行功率控制参数的值之间的对应关系，并通过高层信令如无线资源控制(Radio  Resource Control，RRC)向终端设备指示。或者也可以由协议约定该对应关系。应理解，该对应关系可以是SRI与上行功率控制参数的值之间的直接映射关系，也可以是间接映射关系，例如，该对应关系也可以是SRI所指示的SRS资源数目与上行功率控制参数的值之间的映射，本申请实施例对此不构成限定。
可选地，该第一SRI和该第二SRI也可以对应独立的上行功率控制参数候选值。例如，该第一SRI和该第二SRI都是2bits，可以分别对应四种可能的上行功率控制参数的取值。该第一SRI和该第二SRI可以是由网络侧独立配置的，可以配置成不同的值，也可以配置成相同的值。
可选地，该上行功率控制参数包括确定上行数据的发送功率所用的路损值或用于测量该路损值的下行信号的信息。
该下行信号可以是下行同步信号块(Synchronous Signal Block，SSB)，也可以是信道状态信息参考信号(Channel State Information-Reference Signals，CSI-RS)。该下行信号的信息可以是网络侧通过预先配置的多个下行参考信号中，用于测量该路损值的目标下行参考信号的索引，例如上述公式中的k。也就是说，终端设备可以根据该第一SRI的取值确定对应的一个下行信号的索引k，基于该索引k指示的下行信号进行下行路损测量，从而得到该路损值。
可选地，该上行功率控制参数包括开环功率控制参数和/或闭环功率控制参数。
具体地，该开环功率控制参数取值可以是目标功率Po的指示信息，也可以是路损因子a的指示信息，也可以是闭环功率调整函数f(i)的指示信息。例如，该开环功率控制参数取值可以是网络侧预先配置的多个目标功率Po中一个取值的索引，例如上述公式中的j，也可以是网络侧预先配置的多个路损因子a中的一个取值的索引，例如上述公式中的j，也可以是闭环功率控制的进程索引，例如上述公式中的l。
可选地，该终端设备根据该DCI，确定与该第一SRI对应的上行功率控制参数的值，包括：该终端设备根据该DCI，确定与该第一SRI对应的最大发送功率的值；该终端设备根据该上行功率控制参数的值，确定该PUSCH承载的与该第一SRI对应的第一上行数据的实际发送功率，包括：该终端设备根据该与该第一SRI对应的最大发送功率的值，确定该第一上行数据的实际发送功率。
终端设备可以根据该DCI确定与该DCI中每个SRI对应的最大发送功率的值，然后可以根据该每个SRI对应的最大发送功率的值以及上行发送功率的计算公式，确定该每个SRI对应的上行数据的实际发送功率。
可选地，该终端设备根据该DCI，确定该与该第一SRI对应的最大发送功率的值，包括：该终端设备根据该DCI包括的SRI的数目，确定该与该第一SRI对应的最大发送功率的值。例如，该DCI中包含N个SRI指示，则每个SRI指示(包含了第一SRI)对应的上行数据传输的最大发送功率为P c,max/N，其中P c,max为终端支持的总的最大发送功率。
可选地，该终端设备根据该DCI，确定该与该第一SRI对应的最大发送功率的值，包括：该终端设备根据该DCI包括的该第一SRI所指示的SRS资源的数目，确定该与该第一SRI对应的最大发送功率的值。例如，如果该SRI指示了M个SRS资源，该DCI中包含的所有SRI所指示的总的SRS资源数目为N，则该SRI对应的上行数据传输的最大发送功率为M*P c,max/N，其中P c,max为终端支持的总的最大发送功率。又例如，如果该第一SRI只指示1个SRS资源(表示对应的上行数据传输只在一个panel上传输)，则该第一SRI对应的上行数据传输的最大发送功率为P c,max/2；如果该第一SRI指示了大于1个SRS资源，则该第一SRI对应的上行数据传输的最大发送功率为P c,max。其中P c,max为终端支持的总的最大发送功率。这里假设终端最多支持两个panel，且多层传输是分别在多个panel上传输的。
可选地，该终端设备根据该与该第一SRS资源指示对应的上行功率控制参数的值，确定该PUSCH承载的与该第一资源SRS指示对应的第一上行数据的实际发送功率，包括：该终端设备根据该与该第一SRS资源指示对应的上行功率控制参数的值，确定该第一上行数据的初始发送功率；该终端设备根据该第一上行数据的初始发送功率、该PUSCH承载的上行数据的总初始发送功率以及该终端设备的上行最大发送功率，确定该第一上行数据的实际发送功率。
具体的，终端为该DCI中包含的每个SRI对应的上行数据传输分别确定初始发送功率P n，并计算该DCI调度的PUSCH上的所有上行数据传输的总的发送功率
Figure PCTCN2018071394-appb-000002
(即对所有数据传输的初始发送功率求和)。如果该总发送功率小于等于上行最大发送功率，则该初始发送功率即为实际发送功率；如果该总发送功率大于上行最大发送功率，则需要根据该总发送功率与该上行最大发送功率的比例关系，对初始发送功率进行调整后，得到实际发送功率。例如，调整后的实际发送功率可以表示为：P n,c＝P n*P c,max/P α，其中P c,max为终端支持的总的最大发送功率。
可选地，该第一上行数据为该PUSCH所承载的一部分数据。
具体的，该DCI可以调度包含N个传输层的上行数据传输，该上行数据为该N个传输层中的M个传输层的数据，这里N为大于0的整数，M为小于N且大于0的整数，典型的M＝1。如果该上行数据是该DCI调度的PUSCH所承载的一部分数据，例如是该PUSCH承载的多个数据传输层中的部分数据传输层，则终端需要为传输的每一部分数据都确定对应的SRI，以进行该数据的功率控制。例如，该PUSCH承载两层数据传输，则可以为每一层数据指示一个SRI；如果该PUSCH承载四层数据传输，则可以为每两层数据指示一个SRI。如果该上行数据是该DCI调度的PUSCH所承载的一部分数据，例如是该PUSCH承载的多个数据传输层中的部分数据传输层，则终端需要按照本申请提供的方案，为每个数据传输层都确定各自的实际发送功率。
可选地，该方法还包括：该终端设备根据该实际发送功率，向该网络设备发送该第一上行数据。
当然，终端计算出的实际发送功率不一定实际用于发送该上行数据，也可以用于计算当前PUSCH的功率余量上报(Power Headroom Report，PHR)以上报给网络侧，或者作为一个参考用于计算其他上行信号的发送功率。例如，终端可以根据计算出的上行数据的实际发送功率，加上一定的偏移值，得到SRS的发送功率，此时不一定实际存在上行数据传输。
