Abstract :
We propose a hybrid channel assignment (HCA) scheme in DS-CDMA systems for accommodating integrated voice/data traffic and the required power levels of voice and data traffic are derived. These levels can be used to maintain the required link qualities of all calls. In the proposed scheme, delay-sensitive voice traffic is accommodated in a circuit mode and delay-nonsensitive data traffic is accommodated in a packet mode. The proposed scheme can achieve a high link efficiency with the reduced control overhead by statistically multiplexing voice and data traffic
