3GPP TR 36.873 LTE系統三維通道模型理論與實作:使用者裝置與基地台配對、天線模型和通道係數

3GPP LTE-A (long term evolution-advanced) 4G系統的標準制定已經底定，Rel-12 版本已於2014年Q2完成，全世界3GPP LTE/LTE-A網路的建設也不斷的在擴大、成長。同時，第五代(5th Generation, 5G)行動通訊系統的研發，也開始成為世界各大廠競技的焦點。若想要與世界接軌，就必須要有一個符合國際標準的模擬平台，來評估在系統研究和設計上的系統效能，有鑑於此，本研究著重在於基於技術報告3GPP TR36.873: “Study on 3D channel model for LTE”的規範下，建立出一個具有Wrapped Around和相關性大尺度參數 (Large scale parameters Correlation)特性的三維空間通道模型 (Spatial Channel Model)，使得在研究LTE-A系統的時候，可以得到具有空間特性的通道響應，進而使得在評估具有大型天線下的系統效能能夠更加準確，且本文對於模擬平台中使用到的天線模型、通道係數的產生和使用者裝置與基地台配對的實作上會有更詳細的介紹。

The formulation of the standards of 3GPP long term evolution-advanced (LTE-A) 4G systems is almost complete, with Release 12 being completed in the second quarter of 2014. Moreover, 3GPP LTE/LTE-A networks are being continually developed worldwide. Concurrently, 5G mobile communication systems have attracted considerable research attention among major communication companies worldwide. To ensure practical applicability, simulators must be developed for evaluating the design performance of such systems. Therefore, the objective of this study was to create a spatial channel model that conforms to international standards. To achieve this objective, this study applied the wrap-around method and subjected parameters to large-scale correlation analyses on the basis of 3GPP TR36.873 documentation (“Study on 3D channel model for LTE”) to generate a channel response with spatial properties. This model was integrated with an antenna on a 2D plane to ensure an accurate system performance evaluation. This paper describes the details about the antenna model implementation, channel coefficient generation, and user equipment attachment.
