Abstract
In CDMA-based packet data systems such as HDR and HSDPA which are designed to support high rate services, BSs transmit data packets with a maximum power based on time multiplexing mode such that only one user can be serviced at a time. In this paper, we propose a power-allocation-combined scheduling algorithm for HDR-like systems in which we adopt a code division multiplexing (CDM) transmission method in the downlink common channel in order to utilize channel orthogonality such that we can serve more than one user at a time slot specially when there exist remaining resources after serving the firstly selected user by the scheduler. Simulation results show that the proposed scheme outperforms the conventional scheme as the traffic load increases.
