Devices and methods for assigning spreading codes for reverse common channel messages in CDMA communication systems

摘要

There are provided a common channel message communicating device and method in a CDMA communication system. In a base station of the common channel message communicating device, a control message generator (612) generates a control message including information representative of a spreading code for spreading a reverse common channel message, and a forward common channel transmitter (618) transmits the control message on a forward common channel. In a mobile station, a control message analyser analyses information representative of an assigned spreading code included in the control message received on the forward common channel, a spreading code generator generates a spreading code based on the spreading code information, and a channel transmitter spreads the reverse common channel message by the spreading code and transmits the spread reverse common channel message.
