如图1所示，本公开的一个实施例提供一种SRS功率控制方法100，该方法可以由终端设备执行，包括如下步骤：
S102：接收功率控制参数，该功率控制参数用于确定额外SRS的发送功率。
确定额外SRS的发送功率时需要功率控制参数，因此，该步骤中终端设备可以首先接收来自于网络设备的功率控制参数。
上述功率控制参数可以包括下述至少一种：
额外SRS的目标接收功率(P 0)；
额外SRS的路损计算补偿因子(alpha)；
额外SRS的路损计算参考参考信号(Pathloss reference RS)；
额外SRS的闭环功率控制进程标识(Close loop power control process index)；以及
额外SRS的闭环功率控制调整量。
可选地，上述功率控制参数可以通过下述中的至少一种来配置或指示：
无线资源控制(Radio Resource Control，RRC)信令；
媒体访问控制控制单元(Media Access Control Control Element，MAC CE)信令；以及

S104：根据接收到的功率控制参数，确定额外SRS的发送功率。
终端设备在接收到上述的功率控制参数后，即可根据该功率控制参数确定额外SRS的发送功率。
在本公开实施例中，终端设备接收用于确定额外SRS发送功率的功率控制参数，并根据该功率控制参数确定额外SRS的发送功率，实现了对额外SRS的功率控制。
本公开实施例可以尽量避免因额外SRS功率控制不精确造成的额外SRS信号质量差或额外SRS对通信系统中其他用户造成干扰的问题，提高通信有 效性和可靠性。
对于上述实施例中提到的功率控制参数，可选地，在一个实施例中，该功率控制参数包括第一功率控制参数和第二功率控制参数；其中，第一功率控制参数通过RRC信令配置；第二功率控制参数通过DCI指示。
具体例如，网络设备可以通过RRC信令为终端设备配置额外SRS的下述参数中的至少之一：目标接收功率；路损计算补偿因子；路损计算参考参考信号；以及闭环功率控制进程标识。网络设备还可以通过DCI为终端设备指示额外SRS的闭环功率控制调整量。
对于上述各个实施例中提到的额外SRS，额外SRS可以和遗留(Legacy)SRS在一个TTI内传输，为了精确地实现对额外SRS和遗留SRS进行功率控制，可选地，网络设备可以分别为额外SRS和遗留SRS指示和/或配置功率控制参数，也即，额外SRS的功率控制参数和遗留SRS的功率控制参数是相互独立配置的和/或相互独立指示的；其中，遗留SRS的功率控制参数可以与额外SRS的功率控制参数的种类(或称参数名称)相同，但具体的参数值可以相等也可能不等。
上述提到额外SRS的功率控制参数包括第一功率控制参数和第二功率控制参数，第二功率控制参数通过DCI指示，可选地，第二功率控制参数包括传输功率控制TPC命令，以下将分三个实施方式，对该TPC命令的用途进行说明：
1)该TPC命令用于指示额外SRS的闭环功率控制调整量；或
2)该TPC命令用于指示遗留SRS的闭环功率控制调整量；或
3)该TPC命令用于同时指示额外SRS的闭环功率控制调整量和遗留SRS的闭环功率控制调整量。
针对上述实施方式一和实施方式二，可选地，上述第二功率控制参数除了包括有TPC命令之外，还可以包括有闭环功率控制调整状态指示；其中，该闭环功率控制调整状态指示用于指示该TPC命令应用于：额外SRS闭环功率控制调整；或遗留SRS闭环功率控制调整。
针对上述实施方式一和实施方式二，在一个具体的实施例中，终端设备接收到的DCI的TPC域中新增有1比特(bit)的指示域(即闭环功率控制调 整状态指示)，用于指示TPC命令应用于额外SRS闭环功率控制调整；或应用于遗留SRS闭环功率控制调整。如：0-TPC用于遗留SRS闭环功率控制调整，1-TPC用于额外SRS闭环功率控制调整。
此处，闭环功率控制调整状态指示是用来指示TPC命令的用途(即具体用于额外SRS或遗留SRS闭环功率控制调整)。因此，还可以使用其它类似的术语来表示闭环功率控制调整状态指示。例如，TPC命令类型指示、TPC命令状态指示等。
为详细说明，以下将结合一个具体的实施例进行说明。如图2所示，网络设备可以通过RRC信令，分别为额外SRS和遗留SRS配置功率控制参数。额外SRS功率控制参数和遗留SRS功率控制参数的种类如图2所示，均包括目标接收功率；路损计算补偿因子；路损计算参考RS；以及闭环功率控制进程标识(例如，遗留SRS闭环功率控制进程为0，额外SRS闭环功率控制进程为1)。可选地，额外SRS和遗留SRS的闭环功率控制进程标识不同。
该实施例中，网络设备还通过DCI，分别为额外SRS和遗留SRS指示闭环功率控制调整量。具体如图2所示，终端设备接收到的DCI的TPC域中增加1bit，共3bit。增加的1bit用于指示2bit的TPC命令应用于额外SRS闭环功率控制调整；或应用于遗留SRS闭环功率控制调整。图2中1-TPC表示该TPC命令应用于额外SRS闭环功率控制调整。
该实施例中，终端设备可以基于网络设备RRC信令配置和DCI指示，实现额外SRS与遗留SRS的独立功率控制，从而能够实现更精准的功率控制。
该实施例通过为额外SRS独立配置功率控制参数，可实现额外SRS精确功率控制，避免额外SRS的覆盖问题或干扰问题。
针对上述实施方式三，在一个具体的实施例中，终端设备接收到的DCI的TPC域中增加2bit，共4bit。高2bit用于指示遗留SRS的闭环功率控制调整量；低2bit用于指示额外SRS的闭环功率控制调整量。
为详细说明，以下将结合一个具体的实施例进行说明，参见图3。
如图3所示，网络设备可以通过RRC信令，分别为额外SRS和遗留SRS配置功率控制参数。
额外SRS功率控制参数和遗留SRS功率控制参数的种类如图3所示，均 包括目标接收功率；路损计算补偿因子；路损计算参考RS；以及闭环功率控制进程标识(例如，遗留SRS闭环功率控制进程为0，额外SRS闭环功率控制进程为1)。可选地，额外SRS和遗留SRS的闭环功率控制进程标识不同。
该实施例中，网络设备还通过DCI，分别为额外SRS和遗留SRS指示闭环功率控制调整量。具体如图3所示，终端设备接收到的DCI的TPC域中增加2bit，共4bit。高2bit用于指示遗留SRS的闭环功率控制调整量；低2bit用于指示额外SRS的闭环功率控制调整量。
该实施例中，终端设备可以基于网络设备RRC信令配置和DCI指示，实现额外SRS与遗留SRS的独立功率控制，从而能够实现更精准的功率控制。
该实施例通过为额外SRS独立配置功率控制参数，可实现额外SRS精确功率控制，避免额外SRS的覆盖问题或干扰问题。
在上述多个实施例中，如果额外SRS和遗留SRS在一个TTI内传输，且终端设备在该TTI内需要计算或上报功率余量，终端设备基于如下一项计算所述功率余量：
1)额外SRS的发送功率和遗留SRS的发送功率中的最大者；
2)额外SRS的发送功率；或
3)遗留SRS的发送功率。
具体例如，额外SRS的发送功率大于遗留SRS的发送功率，功率余量可以基于终端设备的最大发送功率和额外SRS的发送功率之差计算得到；又例如，功率余量直接基于终端设备的最大发送功率和额外SRS的发送功率之差计算；或功率余量直接基于终端设备的最大发送功率和遗留SRS的发送功率之差计算。
以上结合图1至图3详细描述了根据本公开实施例的SRS功率控制方法。下面将结合图4描述根据本公开另一实施例的SRS功率控制方法。可以理解的是，从网络设备侧描述的网络设备与终端设备的交互与图1所示的方法中的终端设备侧的描述相同，为避免重复，适当省略相关描述。
