Problems solved by technology

For an indoor wireless access point (access point, AP) using D-MIMO technology, if the directional beam of the current smart antenna is still used (for example, the front-to-back ratio is more than 10dB) to achieve this purpose, facing the forward direction (towards other The RRU direction) radiation is too strong, while the backward radiation is too weak, which is not conducive to improving the BBU edge customer experience, especially not conducive to the BBU edge customer experience in the case of uplink transmission where the client position is not clear

Abstract

The invention discloses a self-adaptive smart antenna, a distributed radio remote unit (RRU) and a wireless communication system, relates to the technical field of antennas, and can ensure a certain backward coverage area of the RRU while expanding an overlapping area between the RRU and improving the capacity and the data transmission rate so as to improve the edge user experience. In the invention, the RRU controls the plurality of diodes of the directional unit according to the control signal from the base band unit (BBU), so as to control the coupling state of the directional unit, flexibly switch the antenna beams of the RRU and select the optimal beam combination. A combination of an omni-directional pattern and a directional pattern satisfying a preset range is included, so a certain backward coverage area of the RRU is ensured while the overlapping area between the RRU is expanded and the capacity and the data transmission rate are improved, so that the edge user experience is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of antennas, and in particular to adaptive smart antennas, distributed RRUs and wireless communication systems. Background technique [0002] In the rapid development of today's wireless communication systems, with the increase in the number of stations and the increase in station density, the overlapping coverage between cells increases, and the problem of co-channel interference is serious. [0003] In order to solve the above problems, a distributed multiple-input multiple-output (distributed multiple-input multiple-output, D-MIMO) technology is introduced. D-MIMO technology can perform joint data transmission and reception through antennas distributed in different spatial positions through a centralized baseband processing unit (baseband unit, BBU) and a distributed remote radio unit (RRU), thereby eliminating the original interference The signal becomes a useful signal. Sin...
