Document Type and Number:
Japanese Patent JP2000516779
Kind Code:
A
Abstract:
Method and apparatus for increasing the communication capacity of a communication system utilizing a time-division, multiple-access communication scheme. A broadcast carrier is defined which is divided into time slots which include a control channel and traffic channels. The traffic channels are used to communicate traffic signals with remote subscriber units. When the traffic channel is not used to communicate traffic signals, carrier signals, whether modulated with information or not, are instead generated, thereby to ensure that signal energy is detected by a mobile subscriber unit when tuning to the broadcast carrier. Two or more signals can be transmitted concurrently upon a single traffic channel utilizing antenna forming techniques wherein the antenna beam pattern used to transmit the two or more traffic signals together encompass an entire cell.
