Title:
パケットデータ移動通信システムにおける逆方向チャネルの送受信装置及び方法
Document Type and Number:
Japanese Patent JP4763051
Kind Code:
B2
Abstract:
An apparatus and method for transmitting and receiving a symbol through a reverse control channel in a mobile communication system for providing packet data are provided. When reverse traffic is present, the apparatus and method can effectively demodulate and decode the reverse traffic. In a method for transmitting a reverse channel in the mobile communication system capable of discontinuously transmitting packet data, a transmission is performed by setting power of a Data Rate Indicator (DRI) channel to a predefined power when packet data is transmitted. When no packet data is transmitted, a transmission is performed by decreasing the power of the DRI channel.
