Title:
無線通信システムにおけるトラフィック・チャネルの最適化を行うシステム及び方法
Document Type and Number:
Japanese Patent JP3523884
Kind Code:
B2
Abstract:
In a wireless communications system (20), a beacon having a first radiation pattern (28) covering a portion of a subscriber service area (34) covered by a base station is transmitted. A subscriber (36) reception quality is then measured to produce a first beacon quality measurement (210). Thereafter, the first radiation pattern is changed to a second radiation pattern (32, 212), and a subscriber reception quality of the beacon transmitted with a second radiation pattern is measured to produce a second beacon quality measurement (214). In response to the first and second beacon quality measurements, a traffic channel radiation pattern (32) is selected (218), wherein such radiation pattern covers a portion of the subscriber service area. In a preferred embodiment, the beacon carrier frequency is the same as the traffic channel carrier frequency.
