摘要

國際5G系統規格制定已正式啟動，ITU-R WP-5D(working party 5D)已確定5G IMT 2020之系統需求並準備接收相關標準建立組織的規格提案。依照ITU-R的規劃，5G將包含三大應用場景，其中Enhanced Mobile Broadband(eMBB)應用須具備數百MHz頻寬或其他新興技術才能達到之系統需求，Ultra-reliable and Low Latency Communications(uRLLC)要求高可靠和低延遲時間，及Massive Machine Type Communications(mMTC)強調大量裝置間通訊與低能源耗損。為了瞭解未來5G之發展技術效能及能否達到系統要求，多個應用於不同場景之模擬平台是需要的。METIS為歐盟成立之研究5G系統的大型計畫，其對5G可能的應用也提出自己規劃的5個應用場景和12個應用於不同場景中的應用環境(Test cases, TC)。本論文針對其所提出的兩個應用環境進行模擬平台之建構與校準。
第一個應用環境是室內大型體育場(TC4)，該應用環境特點在於服務大量人群的行動通訊挑戰。第二個應用環境則是密集都會區中的智能電網(TC5)，該應用環境的挑戰是短暫的延遲時間和低錯誤率，以避免意外發生時某一電站崩壞不及警告周遭電站而導致整體電能網路崩解之情況。本論文已將此二模擬平台完成建構，TC4之模擬平台可準確模擬體育場觀眾席上訊雜干擾比之分佈並以4G系統評估相關效能指標。而本論文所建構的TC5模擬平台可達到METIS要求之99.999%的高可靠度，並於改良各鏈路層的延遲後可達到低於8ms的延遲時間要求。

The specifications of 5G communication systems were about to be developed. According to the planning of ITU-R, the usage scenarios of 5G systems should include three parts: Enhanced Mobile Broadband (eMBB), Massive Machine Type Communications (mMTC) and Ultra-reliable and Low Latency Communications (URLLC). To achieve the requirements of eMBB, hundreds of MHz bandwidth and other emerging technologies are needed. The requirements of URLL care high reliability and low latency mMTCs is characterized by a very large number of connected devices and devices are required to be low cost.
To make sure whether the technologies can achieve the requirements of 5G systems, the development of simulation platform is required, and our purpose in this thesis is to construct the application scenarios that can be run on the platform. METIS is a worldwide project that studies the 5G communication systems and funded by EU. It proposes 5 application scenarios for the 5G usage and 12 test cases based on the 5 application scenarios. In this thesis, we implement and calibrate two of test cases proposed by METIS.
The first scenario is an indoor stadium (TC4) which aims to serve a large number of users. The second is the teleprotection in smart grid network (TC5) whose requirements are very low latency and ultra-reliability. In TC4, the SINR distribution of the tribune in stadium is calibrated and system-level performance is evaluated with 4G LTE-A system. In TC5, we can achieve the 99.999% reliability and latency of less than 8ms, as required by METIS.
