Abstract:
In a time division multiple access based cellular radio telecommunications system, a downlink power control method comprising the steps of:transmitting a first downlink signal, from a base station to a first mobile station, wherein the first downlink signal is transmitted over a first frequency carrier and transmitted at a constant power level during a corresponding timeslot; transmitting a second downlink signal to a second mobile station, wherein the second downlink signal is transmitted at an initial power level during the corresponding timeslot; and attenuating the power level associated with the second downlink signal, wherein the attenuation of the power level associated with the second downlink signal reduces the likelihood that the second downlink signal will interfere with the first downlink signal, and wherein a signal quality associated with the second downlink signal is less likely to become unacceptable as compared to a signal quality associated with the first downlink signal, due to an attenuation in power level.
