1. An uplink frequency selection scheduling method comprising:receiving, by a base station, sounding reference signals (SRS) from a user equipment (UE);
determining, by the base station, a physical resource block (PRB) interference intensity;
determining, by the base station, PRB scheduling priority (SP) based on SRS channel quality (SINR), the determined said PRB interference intensity (Pi) and average noise power, wherein SP=SINR/(1+Pi/PN) where PN is average noise power; and
performing uplink frequency selection scheduling, by the base station, based on the determined PRB scheduling priority.
