摘要
移动通信从第一代到第四代基站规划都采用蜂窝结构,而在实际布防中,特别是密集城区的基站规划中,干扰越来越严重,优化难度也越来越高。充分利用LTE中的MIMO技术,采用联合基站的方式,减少干扰,提升基站吞吐率,并提出虚拟基站概念。与传统的蜂窝相比,基站联合覆盖对提高系统吞吐量,减少干扰,降低切换时间,改善用户体验,特别是高Qos等级用户和VIP用户,有着重要的意义。
Mobile communications from the first generation to fourth-generation base stations have adopted the honeycomb structure plan, but in the actual deployment, especially in dense urban planning base station interference and more serious, optimization difficulty getting higher. Full use of MIMO techniques in LTE, a base station by way of the joint, reduce interference and improve the throughput of the base station, and make the concept of the virtual base station. Compared with the traditional cellular base stations to improve the system throughput joint cover, reduce interference, reducing switching time, improve user experience, especially the high level of user and VIP user Qos has important significance.
