기지국장치 및 기지국장치의 동작 방법

Base station and control method thereof

Abstract

본 발명은, 대형의 안테나장치를 채택하는 기지국장치에 있어서, 방향성 빔포밍 방식 및 다중 입출력 빔포밍 방식을 적용하여 안테나장치를 동작시킴으로써, 채널품질 측정의 오버헤드 및 복잡도를 효과적으로 개선할 수 있고, 더 나아가 인접셀과의 셀 간섭 발생 역시 감소시킬 수 있는 기지국장치 및 기지국장치의 동작 방법을 개시하고 있다.
Disclosed are a base station device and an operation method of a base station device. The base station device is applied with a large antenna device and operates the antenna device by applying a directivity beam forming method and a multiple input and output beam forming method. The present invention efficiently improves an overhead and complexity of measuring a channel quality and reduces cell interference with an adjacent cell.
