Abstract In order to improve the system throughput when the wireless resource are shared by real and no-real services, a new type proportional fairness scheme for real time services occupying no-real time services is proposed, which first carries out union proportional fair scheduling, and then followes the procedure of real-time service occupying no-real-time service. The packet scheduling not only can guarantee the resource allocation of real time services, but also acquire better multi-user diversity gain. Theoretical analysis and simulation show that the suggested scheme can effectively improve the system throughput and spectrum efficiency in comparison with the existing approaches.
