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 assignment, 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 according to information designated by the second signal.
L'invention concerne un procédé d'affectation de canaux communs de paquets dans un système de communication AMRC (accès multiple par répartition de code). Le procédé consiste à émettre un signal de préambule d'accès ayant des informations de canal qui permettent d'accéder à une station de base; à recevoir un signal indicateur d'acquisition de préambule d'accès reçu de la station de base en réponse au signal de préambule d'accès; à émettre un préambule de détection de collision en réponse au signal indicateur d'acquisition de préambule d'accès; à recevoir un premier signal indiquant l'acquisition du préambule de détection de collision et un second signal indiquant l'affection du canal, que la station de base a émis en réponse au signal d'acquisition de collision; et, dès réception du premier signal, à attribuer un canal commun de paquets en fonction des informations données par le second signal.
