Summary:This paper presents the design of VoIP optimized packet scheduler and performance simulations for supporting voice services over downlink evolved UTRA. An efficient packet scheduler taking into account the traffic characteristics and adopting optimal resource allocation is proposed. Results are given for different control channel number settings and packet bundling options. Simulation results show that downlink EUTRA VoIP capacity is mainly limited by control channel number with full dynamic scheduling and packet bundling can help to increase capacity within the control channel limitation. In summary, with packet bundling technique, around 378 and 488 users per sector can be supported in 5 MHz bandwidth with 6 and 8 control channels respectively.
