A method of adjusting a signal quality target at a transceiver of a CDMA radio communication network. The adjustment of the signal quality target ensures that a predefined frame quality target is reached in power control procedure. According to the invention, the method consists in computing for a received frame, a frame quality indicator depending on signal quality indicators measured at slot level in the received frame. The method further comprises a step of adjusting the signal quality target according to the difference between the frame quality indicator and the predefined frame quality target.

The present invention concerns a downlink power control method for adjusting, in a cellular radiocommunication network, the power transmitted by base stations (BS), received with at least a preset minimal power level by a given mobile terminal (MT), towards said mobile terminal (MT), consisting in adjusting, preferably repeatedly, the downlink power level of each of said base stations (BS) according to a specific power distribution criterion, while ensuring a desired communication quality level at said mobile terminal (MT).

This invention relates to a method of modifying a current transmitted power distribution used by at least two base stations transmitting a signal to a mobile station on the macro-diversity principle. A mobile station using this method is also disclosed. According to the invention, the method consists substituting the current transmitted power distribution by a new transmitted power distribution, selected among several hypothetical transmitted power distributions, under the condition that this new transmitted power distribution provides a better quality of service at the mobile station than the current one.

The invention relates to a method of controlling the transmission power of terminals in a CDMA type cellular network. According to the invention, when the transmission power of a number n,of terminals is authorized to be increased by a total amount P dB, a number n,of terminals benefitting from better quality of transmission in the up direction are requested to decrease their total transmission power by P dB. This makes it possible to conserve interference at a constant level in the transmission network, either within a single cell, or within a group of cells.
