The invention provides a method for reducing inter-cell interference in an upper cellular system and a base station applying the method. Firstly, a resource coordination method is executed among the base stations to divide recourse into a resource block subclass; then an interference overload indication method is determined among the base stations, and a disturbed threshold is determined for the resource; then, the base stations carry out the interference overload indication method based on the resource block subclass later; and when receiving an interference overload indication, the base station carries out control strategy to user equipment which uses the resource block subclass recently according to the nature of the interference overload indication and the resource block subclass, so as to achieve the purpose of retraining the interference. The control strategy comprises reduced power, resource usage restriction, transposition of the user equipment in the resource coordination method, refused interference overload indication, adjusted disturbed threshed, adjusted resource coordination method and the like. The invention effectively reduces the intra-cell interference, and has the advantages of less communication signaling cost among the base stations, stronger interference suppression pertinence and flexible, various control methods and the like.

A transmitter is provided having transmission methods that minimize the power needed to ensure reliable reception in a coverage area. In one aspect, data that requires re-transmission as acknowledged mode data is re-transmitted when the power level of the transmission link is higher than a pre-determined level set for reliable reception. The data rate of the re-transmitted data is set according to the difference in the actual power and the pre-determined level. In a second aspect, two transmitting antennae are used to transmit the same signals with a frequency off-set. The frequency off-set can be used to determine the phase of the signals being received at the receiver, so that a phase off-set can be introduced to optimise the effect of interference at the receiver.
