This paper presents two real-time scheduling algorithms to establish data sessions for quality-of-service (QoS) provisioning at next generation Wideband Code Division Multiple Access (WCDMA) network. The real-time bandwidth scheduling (RTBS) implements the early-deadline-first (EDF) scheme to make the schedulable analysis. Based on the channelization code assignment, the RTBS schedules the real-time packets to reduce power consumption. The power resource is consumed only if the packets are not a feasible schedule by the scheduler. The real-time imprecise scheduling (RTIS) is greedy in that the real-time packets yet to be completed at the time can be feasibly scheduled to complete by their deadlines. This scheme tries to schedule as much non real-time packets as possible after setting aside enough radio resource for all the arrived real-time packets to complete on time. Experimental results show that the proposed algorithms perform best in terms of power consumption and session dropped rate.
