2. 2 Motivation In the current AWD, the size of miniband K MB, FPi in each FP i is determined based on FPCT and FPS, as shown in (181) and (225)  FPS is not defined in the whole text  Only FPS i is defined A more general and simpler equation is proposed to fix the problem Apply the updated equation for both DL and UL
