上述表2、表3、表4可以为UE预配置的,当然在实际应用中,上述表2、表3、表4也可以通过NR基站通过广播消息为UE配置。
可选的,上述方法在步骤S303之后还可以包括:
UE确定依据所述调整的功率值的累计值调整上行链路的发射功率时,所述用户设备采用功控方式并依据所述累计值实现所述用户设备上行链路的发射功率调整。上述调整的功率值的累计值可以通过多种方式获取,一种可选的实施方案中,可以通过多条消息携带的调整的功率值之和即为累计值。
下面以一个实际的例子来说明如图3A所示实施例的优点,参阅如图3A所示,如步骤S301A中的调整的功率值为20dB,如采用功控方式并依据表1所示的功率值调整列表实现将发射功率上调20dB,则UE至少需要调整3次,具体的,可以为UE第一次上调8dB,第二次上调8dB,第三次上调4dB,需要进行三次的调整,而依据表2的调整方式,即加大每级功率的调整量,即需要调整2次,第一次上调12dB,第二次上调9dB,如依据表3的调整方式,即采用每级功率不等的调整量,也需要调整3次,第一次上调11dB、第二次上调7dB、第三次上调2dB,依据表4的调整方式,其需要调整2次,即第一次上调16dB,第二次上调4dB。所以对于大部分的功率调整值来说,采用功控方式来调整发射功率 能够有效的减少功率调整的次数,所以其具有发射功率调整次数少,效率高的优点。
参阅图3B,图3B提供了一种链路的功率控制方法,该方法由UE执行,该方法在如图2所示的5G NR的网络结构实现,该方法如图3B所示,包括如下步骤:

上述UE的波束对应性成立或不成立的确认方式具体可以为,UE接收的下行数据的方向(波束)包含在UE发送上行数据的方向(波束)内,则确定UE的波束对应性成立,否则确定UE的波束对应性不成立。例如,UE接收数据的波束为波束1,UE发送数据的波束为波束1、波束2,则确定此时的UE的波束对应性成立,如UE接收数据的波束为波束1,UE发送数据的波束为波束2,则确定此时的UE的波束对应性不成立。

P(i)=min{PCMAX,g(P0,α*PL,f(i))}
其中,PCMAX是UE的最大发射功率,g是一个含有多个变量的函数具体的,g=P0+α*PL+f(i),其中,P0可以为初始接收功率值,α为α1或α2中的一个,PL是估计的路损,f(i)是根据TPC命令确定的调整值。

步骤S303D、UE依据路损信息确定计算发射功率值的选定路损调整值调整值,依据该选定路损调整值计算发射功率值。
P(i)=min{PCMAX,g(P0,α*PL,f(i))}
其中,PCMAX是UE的最大发射功率,g是一个含有多个变量的函数具体的,g=P0+α*(PL+Δ)+f(i),其中,P0可以为初始接收功率值,α为路损系数,PL是估计的路损,Δ为选定路损调整值,f(i)是根据TPC命令确定的调整值。
上述估计路损信息具体可以为具体的路损值,例如10dB,如该路损信息为固定值时,该选定路损调整值即为固定值。上述估计路损信息具体可以为:路损调整值列表,UE可以在路损调整值列表中任意选择一个值作为选定路损调整值,当然还可以为,UE根据自身的类型在路损调整值列表中选择一个值作为选定路损调整值。上述估计路损信息还可以为路损值范围,其范围的确定方式可以有多种,例如可以在消息内携带该范围的具体值,当然还可以是在消息中携带该范围中的一个值,由UE依据该一个值确定该范围,例如,如该范围中的一个值为20dB,则可以确定该范围为【0,20dB】,如该范围中的一个值为-20dB,则可以确定该范围为【-20dB,0】。其选定的方式可以参见路损调整值列表的选定路损调整值的确定方式,这里不在赘述。
