Abstract
The technique of beamforming is to be adopted in 5G NR systems in both DL and UL directions to combat the effect of acute path loss in the Giga hertz frequency region. With beamforming, the measured path loss in the UL and DL directions will be different even if the same carrier frequency is used for both DL and UL, due to the fact that the antenna gains are not unity as in the case in LTE/LTE-A systems. In view of this, embodiments of the present invention provide method and apparatus to handle the mechanism of UL transmit power control.
