What is cell selection criterion?


Cell selection is based on:

  • Qmean: the average SIR of the target cell.
  • Qmin: minimum required SIR.
  • Pcompensation: a correction value for difference UE classes.

S = Qmean - Qmin - Pcompensation

  • If S>0 then the cell is a valid candidate.
  • A UE will camp on the cell with the highest S.
