Path-loss

PL = -57.92 + 20 log(fc) + 37.6 log(d) dB, where:

 

• fc denotes the carrier frequency in Hz, and

 

• d is the propagation distance in km

Shadowing

UL power control

Fractional power control for UE transmit power:

 

Ptx = min (Pmax, P0 + 10 log(N ) + α * PL), where:

 

• Pmax denotes the max UE transmit power

 

• PL denotes the path-loss defined above

 

• N denotes the number of assigned PRBs

 

• α = 0.6, while P0 values are specified in Table 2
