Base station apparatus for adaptively controlling channel density, and control method

摘要

A base station apparatus is provided for adaptively controlling a maximal accommodation channel number per unit area (for example, the coverage area of a cell or sector) in accordance with a traffic quantity without relying upon detachment of a mobile base station and installation of a repeater. Upon inputting of a plurality of baseband signals of a user channel-multiplexed channel group, linear coupling is performed by a weight which is different per area that outputs it, thereby enabling control of the channel density. Additionally, a per-group available channel number is constantly monitored to control the weight while using threshold judgment for the available channel number as a trigger, thus achieving situation-sensitive prompt handleability.
