Abstract :
The W-CDMA system proposed by 3GPP (3rd Generation Partnership Project) offers a new common packet channel (CPCH) to carry small and medium sized packets such as SMS (short message service) data and Web data. Currently, three schemes - the basic scheme, channel monitoring scheme, and channel assignment scheme - have been proposed for the access scheme of CPCH. We propose a new access scheme for CPCH in W-CDMA systems. The proposed scheme is based on the channel assignment scheme and uses an access control method based on the offered load. To show the efficiency of the proposed scheme, we compare the proposed scheme with the channel assignment scheme in view of the throughput performance considering the uplink interference
