Consider a network where the 3GPP-specifed basic open-loop pUscH power control is used, with parameters alpha=0.8 and p0-=-70dBm. Downlink Reference Signal transmit power in the network is increased from 17dBm to 19dBm. How will uplink power control react to the change? It can be assumed that the change in average uplink PRB allocation is negligible.

A.Transmit power of all UEs increases by 2dB.

B.Transmit power of all UEs decreases by 2dB.

C.As the path loss does not change there is no change in open-loop PUSCH transmit power.

D.Transmit power of all UEs decreases by 0.8*2dB=1.6dB.
