Title
(EN) UPLINK POWER CONTROL METHOD AND APPARATUS THEREOF CAPABLE OF REDUCING POWER CONSUMPTION IN BATTERIES BY USING DISTRIBUTION ANTENNAS
(KO) 분산 안테나를 사용하는 이동 통신 시스템에서 상향 링크 전력 제어 방법 및 장치
Abstract
(EN)
PURPOSE: An uplink power control method and apparatus thereof are provided to reduce reception errors and to effectively transmit information by reducing data quantity through distribution antennas. CONSTITUTION: In case a terminal transmits and receives information with a base station by using a distribution antenna, the terminal establishes default values(610,620). The terminal establishes other parameters. The terminal calculates uplink power. The terminal transmits a PUSCH(Physical Uplink Shared Channel)(630). In case the terminal transmits and receives information with the base station by using center antennas, the terminal establishes the uplink power by using the established default values(621).

일반적으로 셀룰러 무선 이동 통신 시스템은 한정된 지역에 복수개의 셀을 구축함으로서 이루어진다. 각 셀에는 해당 셀 내에서의 이동통신을 전담하는 기지국 장비가 셀 영역의 가운데에 위치하게 된다. 상기 기지국 장비로는 무선신호를 전송하는 안테나 및 신호처리 부분이 있으며 셀의 중앙에서 셀 내의 단말들에게 이동통신 서비스를 제공한다. 이와 같이 안테나가 셀의 중앙에 설치되는 시스템은 중앙 집중형 안테나 시스템 (Central Antenna System: CAS)이라고 하며 일반적인 이동통신 시스템이 이 형태이다. 이와 대비되는 시스템으로는 분산 안테나 시스템 (Distributed Antenna System: DAS)이 있으며 DAS의 경우 안테나들을 셀의 서비스영역에 골고루 분산함으로써 CAS와 대비하여 향상된 이동통신 서비스를 제공할 수 있다. 본 발명은 각 기지국의 서비스 영역에 분산되어 배치되어 있는 분산 안테나 시스템 (Distributed Antenna System: DAS)에서 효율적인 상향 링크 전력 제어 방법을 제안한다.
