POWER CONTROL IN EXTERNAL LOOP / OPEN LOOP WEIGHTED IN A DUPLEX COMMUNICATION SYSTEM DIVISION IN TIME.

摘要

A duplex user equipment with spread spectrum time division that uses frames with time intervals for communication, the user equipment comprising: means (82, 88) for receiving, in a first time interval, a first communication having a transmission power level and to receive the transmission power level, an interference level and target settings of a base station; means (92) for measuring a power level of said first communication; means (94) for determining an estimate of road losses based on said measured power level and on said transmission power level of said first communication: means (108, 82) for transmitting a second communication in a second time interval at a level of transmission power to the base station; the user equipment being characterized in that it comprises: means (101) for updating an objective signal to the interference ratio based on the received target settings; means (96, 98, 106) to establish the level of transmission power for the transmission of the second communication in the second time interval by adding the estimate of the losses in the path weighted by a first factor á, which has a value between zero and one, and an estimate of long-term road losses weighted by a second factor (1 ¿á) at the level of interference, at the target signal updated at the interference ratio and at a constant value, being at a quality of the estimated losses on the road determined.
