Patent Searching and Data


Title:
マクロダイバーシティ無線システムにおけるダウンリンク電力制御方法及びその装置
Document Type and Number:
Japanese Patent JP4138028
Kind Code:
B2
Abstract:
A method and apparatus for controlling an amount of downlink power to be applied in each downlink transmission in a macro diversity radio system. Downlink power level is controlled in response to a quality measurement of a corresponding uplink. In accordance with exemplary embodiments, a path gain or a carrier-to-interference ratio of an uplink is measured at a base station in an active set, and subsequently used to proportionally govern a downlink transmission power level for a corresponding downlink. In such a fashion, each downlink handling a mobile station maintains a desired level of robustness, while avoiding introduction of unnecessary system interference.
