技術說明

提出一基於射線追蹤通道資訊之基地台自動佈建演算法，此算法利用欲佈建場域之射線追蹤通道資訊，迭代自動優化基地台佈建位置以反映真實佈建效能，有效降低傳統佈建上可能需實際量測訊號品質才能決定基地台位置的佈建成本，實現以上算法包含以下流程：首先，輸入用戶統計機率分佈並透過電磁模擬軟體產生場域特定射線追蹤通道資訊，下一步，產生初始候選基地台位置，並考量波束成型效應計算出每次迭代的系統效能，接下來檢驗終止條件，若未符合終止條件，於基地台可佈建位置範圍下，持續迭代更新候選基地台位置直至計算出符合一定系統效能(如覆蓋率與系統容量等)的基地台位置或符合終止條件。 An automatic ray-tracing-based cell deployment method is proposed. The method optimizes locations of base stations automatically in an iterative process with ray-tracing-based channel information of area of study to make simulations consistent with performance in a real network. It also reduces cost of time and human power sufficiently compared to the traditional method which needs to measure signal quality of each location in the area of study to deploy cells. The procedure of the method includes following steps: taking statistical user probability distribution as inputs and generating ray-tracing-based channel information from electromagnetic simulation software; generating initial candidate locations of base stations and calculating system performance with consideration of beamforming at each iteration; checking terminal criterion iteratively and update candidate solutions in the region where base stations can be deployed until achieving desired performance or satisfying the criterion; output is approximate optimal cell deployment.
