UE根据以下哪个公式来进行估算PRACH的初始发射功率:()
A.Preamble_Initial_Power=UL_Path_Loss+UL_interference+ConstantValue B.Preamble_Initial_Power=DL_Path_Loss+UL_interference+ConstantValue C.Preamble_Initial_Power=UL_Path_Loss+UL_interference+DefaultConstantValue D.Preamble_Initial_Power=DL_Path_Loss+UL_interference+DefaultConstantValue
