CHANNEL ASSIGNMENT APPARATUS AND METHOD FOR COMMON PACKET CHANNEL IN A WCDMA MOBILE COMMUNICATION SYSTEM

摘要

A common packet channel assignment method in a CDMA (Code Division Multiple Access) communication system is disclosed. The method comprises transmitting an access preamble signal having channel information which is used to access a base station; receiving an access preamble acquisition indicator signal received from the base station in response to the access preamble signal; transmitting a collision detection preamble for detecting a collision in response to the received access preamble acquisition indicator signal; receiving a first signal indicating acquisition of the collision detection preamble and a second signal indicating channel assignement, that the base station has transmitted in response to the collision acquisition signal; and upon receipt of the first signal, allocating a common packet channel accordi ng to information designated by the second signal.
