【発明の名称】セルラ無線電話システムにおける制御チャンネル通信システムおよび方法
Document Type and Number:
Japanese Patent JP2002507348
Kind Code:
A
Abstract:
A first control channel associated with a first cell is communicated in the first cell using a first time/frequency window. The first control channel and a traffic channel are communicated in a second cell using the first time/frequency window. The first control channel may be communicated in the second cell when the first time/frequency window is unassigned to a traffic channel in the second cell. The first time/frequency window may be assigned to a traffic channel in the second cell, and the first control channel may be communicated in the second cell when the traffic channel to which the first time/frequency window is assigned in the second cell is idle. The traffic channel to which the first time/frequency window is assigned in the second cell may be communicated over different carrier frequency bands to thereby frequency hop the traffic channel. The second cell may be served by a base station, and a traffic channel may be communicated between the base station and a radiotelephone using the first time/frequency window at a signal power level which decreases as the distance between the base station and the radiotelephone decreases.
