【摘要】：隨著移動互聯(lián)網(wǎng)及智能終端的快速發(fā)展,數(shù)據(jù)流量呈爆發(fā)性增長,用戶對移動寬帶的需求日益增加。根據(jù)移動運營數(shù)據(jù)統(tǒng)計,90%以上的數(shù)據(jù)流量產(chǎn)生于室內(nèi)。隨著移動“四網(wǎng)協(xié)同”戰(zhàn)略的提出,TD-LTE商用的大規(guī)模開展,GSM、TD-SCDMA、WLAN、TD-LTE四網(wǎng)共存的現(xiàn)象普遍存在。室內(nèi)環(huán)境下各個系統(tǒng)間必會產(chǎn)生各種干擾問題,室內(nèi)覆蓋將是未來建設(shè)的重點與難點。根據(jù)某省市移動統(tǒng)計數(shù)據(jù)分析,WLAN作為對GSM和TD-SCDMA網(wǎng)絡(luò)的有效補充,承載著大部分的室內(nèi)流量,研究與分析TD-LTE與WLAN系統(tǒng)間的干擾,提出相應(yīng)的規(guī)避措施,對未來TD-LTE的規(guī)劃與部署具有非常重要的意義。本文的主要工作和成果如下：1)介紹了TD-LTE和WLAN兩個系統(tǒng)的基本原理、技術(shù)特點等,并針對室內(nèi)多系統(tǒng)共存干擾問題,闡述了干擾產(chǎn)生的原理及危害,研究了不同干擾的分析方法。2)分析了TD-LTE和WLAN系統(tǒng)可能存在的干擾類型以及干擾模式,通過規(guī)范的確定性分析方法,明確了合路部署場景下的隔離度要求和獨立部署場景下的空間隔離距離要求。并結(jié)合移動現(xiàn)網(wǎng)和不同廠家設(shè)備,對以上兩種場景分別進行干擾測試。測試結(jié)果表明,TD-LTE與WLAN系統(tǒng)間的干擾主要是獨立部署場景下TD-LTE基站對WLAN AP的干擾。3)將理論計算和現(xiàn)場測試結(jié)果進行對比,分析其產(chǎn)生干擾的原因。在研究各種干擾規(guī)避措施的基礎(chǔ)上,提出相應(yīng)的規(guī)避措施,并再次進行測試驗證,證明提出的措施是否合理、有效、可實施。為TD-LTE與WLAN室內(nèi)覆蓋過程中產(chǎn)生的干擾問題,提供了有價值的參考依據(jù)。
[Abstract]:With the rapid development of mobile Internet and intelligent terminals, the data flow is increasing explosively, and the demand for mobile broadband is increasing day by day. According to the statistics of mobile operation data. More than 90% data traffic is generated indoors. With the development of mobile "four-network cooperation" strategy, the large-scale development of TD-LTE commercial system will lead to the development of GSM-TD-SCDMA-WLAN. The phenomenon of the coexistence of TD-LTE four nets is common. In the indoor environment, there will be a variety of interference between the systems, indoor coverage will be the focus and difficulty of the future construction. According to some provinces and cities mobile statistical data analysis. As an effective supplement to GSM and TD-SCDMA networks, WLAN is carrying most of the indoor traffic. The interference between TD-LTE and WLAN system is studied and analyzed. Put forward the corresponding circumvention measures. The main work and results of this paper are as follows: 1) the basic principles and technical characteristics of TD-LTE and WLAN are introduced. Aiming at the interference problem of indoor multi-system coexistence, the principle and harm of interference are expounded. The possible interference types and interference modes in TD-LTE and WLAN systems are analyzed, and the canonical deterministic analysis method is used. It clarifies the isolation degree requirement under the combined deployment scenario and the space isolation distance requirement under the independent deployment scenario, and combines the mobile network and the different manufacturer equipment. The interference tests are carried out on the above two scenarios, and the test results show that. The interference between TD-LTE and WLAN system is mainly the interference of TD-LTE base station to WLAN AP under the independent deployment scenario. 3) the theoretical calculation and field test results are compared. On the basis of studying various kinds of interference circumvention measures, the corresponding circumvention measures are put forward and tested again to prove whether the proposed measures are reasonable and effective. It can be implemented. It provides a valuable reference for the interference in the process of TD-LTE and WLAN indoor coverage.
