Abstract

The embodiment of the invention provides an active-passive integrated antenna apparatus and a base station. The active-passive integrated antenna apparatus comprises an active antenna unit and a passive antenna unit. The active antenna unit includes: a first interface, which is used for receiving an active antenna signal and an electric modulation signal, sending the active antenna signal to an active antenna oscillator and sending the electric modulation signal to the passive antenna unit; and a passive antenna oscillator, which is used for transmitting a passive antenna signal. The passive antenna unit includes: a second interface, which is used for receiving a passive antenna signal and an electric modulation signal, sending the passive antenna signal to a passive antenna oscillator, and adjusting an antenna beam downward inclination angle in the passive antenna unit according to the electric modulation signal; and the passive antenna oscillator, which is used for transmitting the passive antenna signal. According to the apparatus and the base station, the active-passive integrated antenna structure can be simplified and electric modulation signal transmission reliability can be improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to an active and passive integrated antenna device and a base station. Background technique [0002] Due to the advantages of AAS (Active Antenna System, active antenna system) with flexible beamforming capability, which is convenient for remote control and management, communication base station antennas are now evolving from traditional PAS (Passive Antenna System, passive antenna system) to AAS . However, the number of existing base stations is huge, and it is impossible to replace the PAS of all base stations with AAS in the short term. In order to ensure the good operation of the existing network, active and passive integrated antennas with integrated design of AAS and PAS are usually used for transition. [0003] In the prior art, in the integrated antenna of AAS and PAS, AAS uses CPRI (the Common Public Radio Interface, common public radio interface) to ...
