Title:
SELF-ADAPTIVE INTELLIGENT ANTENNA, AND DISTRIBUTED RRU AND WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/012672
Kind Code:
A1
Abstract:
Disclosed are a self-adaptive intelligent antenna, a distributed remote radio unit (RRU), and a wireless communication system, which relate to the technical field of antennas, and can expand an overlapping area between the RRUs and improve the capacity and data transmission rate, while also ensuring a certain backward coverage area of the RRU, so as to improve the edge user experience. In the present application, the RRU controls a plurality of diodes of a directional unit according to a control signal from a baseband unit (BBU), so as to control the coupling state of the directional unit, flexibly switch an RRU antenna beam, and select an optimal beam combination. A combination of an omnidirectional pattern and a directional pattern that meets a preset range is comprised, thereby making it possible to expand an overlapping area between the RRUs and improve the capacity and data transmission rate, while also ensuring a certain backward coverage area of the RRU, so as to improve the edge user experience.
