Description

[Technical Field]

[0001] The present invention relates to circuit architectures for radio units, base stations and satellite communications in wireless communication systems. [Background technology]

[0002] Wireless communication systems with multiple antennas can be divided into two types based on their antenna architecture: active antennas and passive antennas. Conventional 4th generation (4G) mobile communication base stations (BSs) primarily use passive antennas, characterized by separating the radio frequency (RF) components from the antenna. The RF components are located inside the remote radio head (RRH), and the antenna is located outside the RRH and connected to the RRH via a cable. Unlike passive antenna architectures, active antennas integrate the RF components with the antenna, avoiding or reducing cable loss and making them more suitable for wireless communication systems with a large number of antennas. Due to the advantages of active antennas and the increased number of antennas, 5th generation (5G) mobile communication base stations often use active antennas, for example, by integrating the RF components and antennas into the base station's radio unit (RU).

[0003] In active antenna systems, the prior art has used a single printed circuit board (PCB) as the mainstream architecture, integrating antennas, radio frequency components, and baseband digital circuits onto the PCB using a single multilayer PCB architecture. For example, U.S. Patent Publication Nos. US9391370B2, US10201073B2, and US10290920B2 all use similar multilayer PCB architectures, integrating antennas, radio frequency components, and baseband digital circuits onto a single PCB. However, while the use of a single multilayer PCB is the mainstream of prior art in active antenna system applications with a large number of antennas, such as wireless units, base stations, and satellite communications, it has the following drawbacks. First, the antenna, radio frequency components, and digital circuits are all integrated onto a single PCB, and the heat dissipation area is limited to the area of ​​the single PCB, resulting in low heat dissipation efficiency and difficulty in heat dissipation. Second, because the antenna, high-frequency components, and digital circuits are integrated onto a single printed circuit board, the components are closely spaced, making them susceptible to noise and interference issues such as electromagnetic interference (EMI) and electromagnetic compatibility (EMC). Furthermore, because a single printed circuit board is used, aging or damage to the printed circuit board or its internal components can easily cause the entire system to stop working, resulting in a short service life and low stability. Furthermore, the high level of integration makes it difficult to maintain, replace, or update damaged components. Furthermore, because multi-layer printed circuit boards use a three-dimensional structure to arrange components, their fabrication is complex, significantly increasing production costs. Furthermore, the complex fabrication process also results in a low yield rate in mass production.

[0004] Based on the above, the prior art still has drawbacks such as poor heat dissipation, high noise and interference, short lifespan, low stability, poor maintenance, high cost, and low yield rate in mass production, and there is still room for improvement. Summary of the Invention [Problem to be solved by the invention]

[0005] In order to solve the above-mentioned shortcomings of the conventional technology, the present disclosure uses a multiple printed circuit board architecture instead of a single printed circuit board, and allocates, for example, active antennas required for wireless units, base stations, and satellite communication systems, such as antennas and high-frequency components, digital circuits such as fronthaul interface modules, communication digital signal processing modules, beamforming modules, and baseband digital circuit modules, and power modules to multiple printed circuit boards, and by appropriately arranging each module on the multiple printed circuit boards, they can work together to achieve the required functions and optimize the overall performance.

[0007] A further aspect of the present disclosure provides a circuit architecture for a wireless unit including a plurality of printed circuit boards capable of transmitting data and / or signals between each other via any digital and / or analog interface, at least one of the printed circuit boards including an antenna module and at least another printed circuit board including a fronthaul interface module. RF Front-end modules and RF The printed circuit board including the fronthaul interface module may include a communication digital signal processing module and a beamforming module in addition to the fronthaul interface module. In addition to the printed circuit board including the antenna module and the printed circuit board including the fronthaul interface module, another printed circuit board including a power supply module may be included.

[0008] A further aspect of the present disclosure provides a circuit architecture for a wireless unit including a plurality of printed circuit boards capable of transmitting data and / or signals between each other via any digital and / or analog interface, at least one of the printed circuit boards including an antenna module and at least another printed circuit board including a power supply module. RF Front-end module, RF A communication module, a digital signal processing module, and a beamforming module may be included.

[0009] A further aspect of the present disclosure provides a circuit architecture for base stations and satellite communications, comprising a plurality of printed circuit boards capable of transmitting data and / or signals between each other via any digital interface and / or analog interface, at least one of the printed circuit boards including an antenna module and at least another printed circuit board including a baseband digital circuit module. RF The printed circuit board including the baseband digital circuit module may also include a front-end module. RF In addition to the printed circuit board including the antenna module and the printed circuit board including the baseband digital circuit module, another printed circuit board including a power supply module may be included.

[0010] A further aspect of the present disclosure provides a circuit architecture for base stations and satellite communications, comprising a plurality of printed circuit boards capable of transmitting data and / or signals between each other via any digital interface and / or analog interface, at least one of the printed circuit boards including an antenna module and at least another printed circuit board including a baseband digital circuit module.

In addition to the printed circuit board including the antenna module and the printed circuit board including the baseband digital circuit module, another printed circuit board including a power supply module may be included.

[0011] A further aspect of the present disclosure provides a circuit architecture for base station and satellite communications, comprising a plurality of printed circuit boards capable of transmitting data and / or signals between each other via any digital and / or analog interface, at least one of the printed circuit boards including an antenna module and at least another of the printed circuit boards including a power supply module. RF Front-end module, RF The module may include a beamforming module, a baseband digital circuit module, and a baseband digital circuit module. [Effects of the Invention]

[0012] Based on the above, the circuit architecture of the wireless unit, base station, and satellite communication disclosed herein employs multiple printed circuit boards and arranges each module on multiple printed circuit boards. This not only achieves the functionality required by existing systems, but also optimizes overall system performance and provides the following new advantages: First, the use of multiple printed circuit boards provides a larger heat dissipation area and better heat dissipation than a single printed circuit board. Second, circuit components can be arranged on multiple printed circuit boards, allowing components that are prone to electromagnetic interference and electromagnetic compatibility issues to be arranged on different printed circuit boards, increasing their spacing and reducing noise and interference. Furthermore, the use of a multiple printed circuit board architecture provides greater stability and lifespan than a single printed circuit board architecture. For example, in the application of a wireless unit with multiple antennas, especially when there are many antennas, damage to the printed circuit boards or their internal components of some antenna branches may result in performance defects, but the overall system may still operate normally, thereby extending its lifespan. Furthermore, damage to internal components of some printed circuit boards can be replaced simply by replacing the damaged printed circuit board and its components rather than having to replace the entire system, making maintenance easier. Furthermore, the fabrication complexity of the multi-printed circuit board architecture is relatively low, which reduces the overall circuit cost and improves the yield rate in mass production. Furthermore, the circuit architecture disclosed herein is particularly suited to wireless communication systems with a large number of antennas, such as massive multiple-input multiple-output (Massive MIMO) base stations.Under the condition of the same data transmission speed, a large-scale multi-input multi-output antenna base station can effectively reduce the transmit power of user equipment (UE) such as cell phones and base stations as the number of antennas increases. The reduced transmit power is proportional to the number of antennas, meaning that the more antennas there are, the greater the transmit power reduction. This reduces the power consumption of cell phones and base stations, achieving the green technology effects of energy saving and carbon reduction.

[0013] As a result, the circuit architecture disclosed herein can achieve the desired functionality while optimizing overall performance and providing additional benefits such as better heat dissipation efficiency, reduced noise and interference, a long service life, easy maintenance and upgrades, suitability for mass production, low circuit costs, and energy-saving and carbon-reducing effects. Among these, the good heat dissipation effect makes it more suitable for base stations and satellite communication systems with high heat dissipation requirements. The reduced noise and interference improves the stability and performance of base stations and satellite communication systems. The long service life and easy maintenance and upgrades make it more suitable for base station and satellite communication system applications. In particular, for base station applications, where communication operators typically require base stations to have a long lifespan of 10 years or more, updates to international communication standards may require modifications or upgrades to the internal circuits. Furthermore, the suitability for mass production, low circuit costs, and energy-saving and carbon-reducing effects are beneficial for the mass construction and layout of fifth-generation (5G) and even future sixth-generation (6G) mobile communication base stations.
