Abstract:
1. A method for open loop power control in a communication system, the method comprising: receiving pilot signals from a scheduling cell that schedules a mobile station, and neighboring cells located adjacent to the mobile station; calculating the number of neighboring cells having pathlosses that are less than a threshold; calculating a target Signal-to-Interference Ratio (SIR) of the mobile station using the number of neighboring cells having pathlosses that are less than the threshold; measuring the pathloss of the scheduling cell and calculating uplink transmission power using the measured pathloss of the scheduling cell and the calculated target SIR; and transmitting data with the calculated transmission power, wherein the calculation of the target SIR comprises setting a value acquired by lowering a reference SIR by a product of a parameter for determining the amount of lowering from the reference SIR and the number of neighboring cells having pathlosses that are less than the threshold as the target SIR.
