Cells re-use partition in a mobile communication system.

摘要

A re-use partition of cells in a mobile communication system has an outer cell (30) and an inner cell (20) which is provided in said outer cell (30). Interval of cells using the same channel or the same frequency in inner cells is shorter than interval in outer cells, as nature of re-use partition. Communication between a base station and a mobile station is carried out by using a channel of higher received level of an outer cell channel or an inner cell channel. A base station has a first beam tilt antenna having tilt angle ( theta out) for an outer cell (30), and a second beam tilt antenna having tilt angle ( theta in) so that theta in is larger than theta out. A speech channel and a control channel are provided for each of said first antenna and said second antenna. <IMAGE>
