원격 장치의 속도를 결정하고(405), 결정된 속도에 기초하여 목표 임계치를 전력 제어 임계치로서 할당함으로써(410), 스프레드 스펙트럼 통신 시스템에서의 전력 제어가 행해진다. 프레임 품질 정보와 목표 임계치에 기초하여 순간 임계치가 생성된다(415). 원격 장치로부터 전송된 전력 제어군의 에너지가 순간 임계치와 비교되고, 전력 조정 명령이 결정된다. 전력 조정 명령은 원격 장치에 전송되어 원격 장치가 그에 따라 그 전력을 조정하도록 지시한다. Power control in a spread spectrum communication system takes place by determining a speed of a remote unit (405) and assigning as a power-control threshold a target threshold based on the determined speed (410). An instantaneous threshold value is created (415) based on frame-quality information and the target threshold. An energy of a power-control group transmitted (430) from a remote unit is compared to the instantaneous threshold value and a power-adjustment command is determined. The power-adjustment command is transmitted to the remote unit instructing the remote unit to adjust its power accordingly.
