摘要 LTE系统上行链路中采用SC-FDMA技术,要求为用户分配的资源块(RU)在频域上连续分布,同时位于扇区边缘的用户因为收到较为严重的外扇区干扰性能有很大恶化。文中主要针对这两个问题,在传统算法的基础上,分别提出一种改进的PF频域分组调度算法和一种改进的部分功率控制算法。仿真结果表明,二者结合能较好地改善系统性能,特别是边缘用户的性能。 With SC-FDMAas its uplink key technology, LTE req Additionally, performance of the edge user deteriorates greatly order to tackle above two problems, this paper proposes two algo PF frequency domain packet scheduling algorithm and the improved results indicate that the combination of these two algorithms fai uires successive uplink RU allocation for users due to the interference from other sectors. In rithms based on traditional ones: the improved fractional power control algorithm. Simulation fly improves the performance of the system, and in particular, of the edge user.
