Patent ID: 8811266

Claim:
A method for performing uplink scheduling for a first user equipment by a first base station, the method comprising: receiving, by the first base station from the first user equipment, a sounding reference signal (SRS) on a frequency band having an uplink interference occurring therein with respect to a second base station, the SRS being transmitted by the first user equipment at a transmission power set to a power level lower than those of other frequency bands, or at a transmission power set to ‘0’; and allocating, by the first base station, an uplink resource for the first user equipment based upon the frequency band, wherein the frequency band is decided by the first base station based upon uplink scheduling information on a second user equipment of the second base station, wherein the transmission power of the SRS is decided considering the uplink scheduling information and a path loss from the first user equipment to the second base station, and wherein the uplink scheduling information is acquired by the first user equipment and transmitted to the first base station.
