摘　　要：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。According to the frame characterristic of TD-SCDMA system, an improved boundary strategy dynamic channel allocation （MB DCA） scheme applicable for the system was proposed, which is a mixed data rate and small grouping borrowed MB DCA scheme. This scheme can solve the problem of low channel borrowed efficiency in the case of mixed data rate, make MB strategy more flexible, and improve system capability through small grouping borrowed. Simulation results show that the proposed scheme can update data service capability and increase channel utilization efficiency without affecting voice service performance.
