【摘要】：如今伴随着移动通信技术的快速发展,移动通信中对频率资源的需求不断提升。针对于频率资源有限的问题,TD-LTE技术具有其他技术无法比拟的优势。TD-LTE技术具有非常高的频率利用率,相比HSPA等3G技术的3倍以上。TD-LTE技术在频率利用效率、速率、时延等方面具有独特的优势,可以给人们提供丰富多样的服务,在一定程度之上推动了移动产业的发展。由于TD-LTE无线网络规划与2G、3G网络的规划具有一定的相似性,但同时也有很多不同点。本文首先对TD-LTE的系统模型和物理层等相关技术进行基本分析,相关技术包括包括TD-LTE物理层技术、MIMO技术、OFDM技术。在模型之上结合无线网络的规划原则分析TD-LTE系统的无线网络覆盖和容量。从链路预算和容量指标等方面分析了TD-LTE网络规划方面的特点和评估标准,重点分析了无线接入网络的参数,如范围、容量和地址。同时本文从无线网络站地选择方面分析了TD-LTE系统的站选原则和规划模型。针对TD-LTE系统无线网络的覆盖存在的问题,本文提出了RF优化流程,以哈尔滨市城区为例进行实地采样与分析,结果表明,加入RF优化大大提高了市区TD-LTE网络的连续覆盖效果。针对RF优化流程无法解决的覆盖不足问题,本文再次提出了无线站点规划方案,基于U-Net软件仿真结果表明,合理新增站点有效的提升了原弱覆盖区域的覆盖效果。
[Abstract]:With the rapid development of mobile communication technology, the demand for frequency resources in mobile communication is increasing. To solve the problem of limited frequency resources, TD-LTE technology has more advantages than other technologies. TD-LTE technology has a very high frequency utilization ratio. Compared with 3G technology such as HSPA, TD-LTE technology has more than three times the efficiency and rate of frequency utilization. Delay and other aspects have unique advantages, can provide people with a variety of services, to a certain extent, promote the development of the mobile industry. Because of the similarity between TD-LTE wireless network planning and 2GN 3G network planning, there are many differences at the same time. In this paper, the system model and physical layer of TD-LTE are analyzed. The related technologies include TD-LTE physical layer and TD-LTE. The wireless network coverage and capacity of TD-LTE system are analyzed based on the wireless network planning principle. The characteristics and evaluation criteria of TD-LTE network planning are analyzed from the aspects of link budget and capacity index, and the parameters of wireless access network, such as range, capacity and address, are emphatically analyzed. At the same time, this paper analyzes the TD-LTE system station selection principles and planning model from the wireless network site selection. Aiming at the problem of wireless network coverage in TD-LTE system, this paper puts forward the RF optimization flow, taking Harbin urban area as an example to sample and analyze on the spot. The results show that the continuous coverage effect of urban TD-LTE network is greatly improved by adding RF optimization. Aiming at the insufficient coverage problem which can not be solved by RF optimization process, this paper proposes a wireless site planning scheme again. The simulation results based on U-Net software show that the new site can effectively improve the coverage effect of the original weak coverage area.
