Abstract

Antena adaptacyjna, zawierająca co najmniej dwa moduły (H1, H2) i co najmniej jedną kolumnę promienników umieszczonych na każdym z modułów anteny, charakteryzuje się tym, że moduły (H1 i H2) są umieszczone krawędziowe obok siebie i każdy z modułów ma co najmniej 8 promienników wzdłuż osi pionowej modułu (H1, H2). Osie wynikowe azymutów anteny dzielą 120°-wy sektor kątowy na równe części. Sposób polega na tym, że modyfikuje się wiązkę i przesyła się zmodulowany sygnał LTE. Za pomocą UE określa się, wartość wskaźnika CQI, który transmituje się w kanale zwrotnym UL do wszystkich elementów anteny. Przy użyciu BBU wybiera się optymalną dla wiązki ścieżkę odpowiadającą najwyższemu CQI. Zmodulowany sygnał LTE mnoży się przez wektory sterujące K i L układu przemnażania w module RRH i dalej transmituje się do dzielnika mocy i kolejno do promienników jednej z polaryzacji.An adaptive antenna, containing at least two modules (H1, H2) and at least one column of radiators located on each of the antenna modules, is characterized in that the modules (H1 and H2) are placed side by side and each module has at least 8 radiators along the vertical axis of the module (H1, H2). The resulting azimuth antenna axes divide the 120 ° angular sector into equal parts. The method consists in modifying the beam and transmitting the modulated LTE signal. The UE uses CQI to determine the value of the CQI indicator that is transmitted on the UL return channel to all antenna elements. When using BBU, the beam path optimal for the highest CQI is selected. The modulated LTE signal is multiplied by the control vectors K and L of the multiplication system in the RRH module and further transmitted to the power divider and successively to the radiators of one of the polarities.
