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 Lognormal fading, with:
  • standard deviation = 8 dB
  • correlation distance = 50 m
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
