Abstract
본 발명은 이동통신 시스템중 CDMA방식의 이동국의 송신출력을 제어하는 장치 및 방법에 관한 것으로, 기지국으로부터 수신한 수신신호레벨에서 기지국과 이동국간의 경로손실을 예측하는 경로손실산출수단과 상기 경로손실산출수단이 예측한 경로손실과 현재 송신출력을 비교하여 제어신호를 발생하는 제어신호 발생수단과 상기 제어신호발생수단이 제공하는 제어신호에 따라 이동국의 송신 출력을 적절한 레벨로 증폭하는 출력증폭수단으로 구성되었다.The present invention relates to an apparatus and method for controlling a transmission output of a CDMA mobile station in a mobile communication system, comprising: path loss calculating means for predicting a path loss between a base station and a mobile station at a received signal level received from a base station; A control signal generating means for generating a control signal by comparing the path loss predicted by the means with a current transmission output, and an output amplifying means for amplifying the transmission output of the mobile station to an appropriate level according to the control signal provided by the control signal generating means. It became.
본 발명의 효과는 전력레벨을 디지탈 값으로 환산하여 처리하므로 기지국에서 수신전력레벨이 일정하도록 이동국에서 다이나믹 레인지를 자유롭게 조절할수있고, 전력제어 스텝도 임의로 설정할 수 있다. 또한 전력 제어를 이동국에서 하므로 다른 이동국들의 신호에 간섭을 일으키지 않아 동일 주파수로 운용되는 대역확산 CDMA방식을 구현할 수 있다.The effect of the present invention is to convert the power level into a digital value so that the dynamic range can be freely adjusted in the mobile station so that the reception power level is constant at the base station, and the power control step can be arbitrarily set. In addition, since the power control is performed by the mobile station, a spread spectrum CDMA method operating at the same frequency without causing interference with signals of other mobile stations can be implemented.
