因應目前4G網路需求增加,佈建基站需要比原本3G更為密集,由於部分區域新增基站點不易,所以業者轉以強波器來提升客戶信號,但是強波器可控性與穩定性不如基地台,造成特定基站產生嚴重干擾。
本文利用實驗環境比較上行通道已知調度與現行Comp差異,明確訂定適合的條件與限制,藉由實際干擾已知基站驗證推得結論,並實際投入干擾未知基站,將理論推廣至實務應用,降低干擾造成的影響並提升用戶體驗。
With the increasing demand of 4G network, higher density of base station installation becomes indispensable. Given the difficulty of new deployment in some area, operators use amplifiers(boosters) to improve signal reception as substitute; however, amplifiers(boosters) are less controllable and stable than base stations, thus creates sever interference in some cases.
This article(thesis) compares the difference between the known allocations of uplink channels and present Comp in the Laboratory with well-defined criteria and restrictions. Derives the corresponding data via interfering specific base stations, and then apply these results to un-interfered base stations in the fields. Summarizing all theoretic work to practical implementation; decreases the impact caused by interference and then improves user experiences.
