A Novel Intercell Interference Control Based on Scheduling for TD-SCDMA HSUPA
-
摘要: 该文提出了系统RoT的概念，以及利用系统RoT进行资源调度的策略，从而控制TD-SCDMA HSUPA(High-Speed Uplink Packet Access)技术中小区间干扰水平。在该策略中，系统RoT充分考虑了用户位置信息，因此在TD-SCDMA HSUPA这种分散调度模式下也能很好地控制小区间的干扰。由系统仿真表明，该策略显著改善了系统性能。Abstract: In this paper, system RoT and a novel intercell interference control scheme for TD-SCDMA HSUPA(High-Speed Uplink Packet Access) based on system RoT is presented. The scheme controls the user admission and the resource distribution according to the information of users geometry. System simulation results proves that this scheme improves the system performance.
