Pt=Pmax*min{1,max[Rmin,(CL/CL_x-ile)^gama]}

这个是36.942中关于UE功率控制的一个公式,下面一段话是

where Pmaxis the maximum transmit power, Rminis the minimum power reduction ratio to prevent UEs with good channels totransmit at very low power level, CLis the path couplingloss defined as max{path loss-G_Tx-G_Rx, MCL}, where pathloss is propagation loss plusshadowfading, G_TX is the transmitter antenna gain in the direction of thereceiver, G_RX is the receiver antenna gain in the direction of the transmitter and CLx-ileis the x-percentile CL value. With this power controlequation, the x percent of UEs thathave the highest couplingloss will transmit at Pmax.  Finally,0<g<=1 is the balancing factor for UEswith bad channel and UEs with good channel:

我现在不确定CL和CL x-ile的单位,常理来看似乎不应该是dB,但是把dB转化为数值后再算,结果似乎不对,请了解的人,解答一下,谢谢
