BASE STATION APPARATUS AND SECTOR CONTROL METHOD

摘要

The direction of arrival detection section 116 detects the direction of arrival of signals transmitted from various mobile stations based on information output from the reception processing section 113. The traffic detection section 115 detects traffic of the respective mobile stations based on information output from the direction of arrival detection section 116. The sector control section 117 controls the switching sections 102 and 108, spreading section 111 and despreading section 104 so that sectors are rotatedbasedon information output from the traffic detection section 115. This makes it possible to reduce communication load in a handover area between sectors and increase the channel capacity of the system.
