针对TD-SCDMA系统帧结构的特点,提出了一种可移动边界动态信道分配(MBDCA)改进方案——混合数据速率、小分组借用的MB DCA方案,解决了在混合数据业务速率情况下系统信道借用率较低的问题。通过小分组借用,增加了可移动边界(MB)策略的灵活性,使系统性能得到进一步提高。仿真结果表明,此方案在不影响语音业务性能的情况下,提高了数据业务性能和系统的信道利用率。
In view of the characteristics of TD-SCDMA system frame structure, this paper proposes a MBDC scheme for mobile border dynamic channel allocation (MBDCA), which is a hybrid data rate and small packet borrowing scheme to solve the problem that the system channel Low borrowing rate problem. Borrowing through small packets increases the flexibility of a moveable boundary (MB) policy to further improve system performance. Simulation results show that this scheme can improve data service performance and system channel utilization without affecting the performance of voice services.
