METHODS AND DEVICES FOR BEAMFORMING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18036449 titled 'METHODS AND DEVICES FOR BEAMFORMING
Simplified Explanation
Abstract
Various embodiments of the present disclosure provide a method for beamforming. The method, which may be implemented at a network node, includes obtaining channel information of a terminal device, determining a self-correlation factor of the terminal device based on the channel information, determining the main lobe width based on the relationship between the self-correlation factor and the main lobe width, determining a weight vector on at least one transmitting antenna based on the determined main lobe width, and transmitting a message to the terminal device using the weight vector on the at least one transmitting antenna.
Explanation
- The patent application describes a method for beamforming, which is a technique used in wireless communication systems to improve signal quality and coverage.
- The method involves obtaining channel information of a terminal device, which refers to the characteristics of the wireless channel between the network node and the terminal device.
- The self-correlation factor of the terminal device is determined based on the channel information. The self-correlation factor represents the correlation between the signals received by the terminal device.
- The main lobe width, which determines the directionality of the transmitted signal, is determined based on the relationship between the self-correlation factor and the main lobe width.
- A weight vector is then calculated based on the determined main lobe width. The weight vector represents the relative strength and phase of the signals transmitted from each antenna.
- Finally, the network node transmits a message to the terminal device using the calculated weight vector on the transmitting antenna(s), resulting in improved signal reception at the terminal device.
Potential Applications
- This technology can be applied in various wireless communication systems, such as cellular networks, Wi-Fi networks, and satellite communication systems.
- It can improve the signal quality and coverage in areas with high interference or weak signal strength.
- Beamforming can be particularly beneficial in crowded environments, such as stadiums, airports, and urban areas, where multiple devices are competing for limited wireless resources.
Problems Solved
- Beamforming helps mitigate the effects of interference and multipath fading, which can degrade the quality of wireless signals.
- By focusing the transmitted signal towards the intended receiver, beamforming improves the signal-to-noise ratio and reduces the likelihood of errors or dropped connections.
- This technology also enables better utilization of available spectrum, as it allows for more efficient transmission and reception of signals.
Benefits
- Improved signal quality and coverage: Beamforming enhances the received signal strength and reduces signal degradation, leading to better overall communication performance.
- Increased capacity: By directing the signal towards the intended receiver, beamforming allows for more efficient use of available resources, enabling higher data rates and accommodating more simultaneous connections.
- Enhanced user experience: With improved signal quality and coverage, users can enjoy faster and more reliable wireless connections, resulting in better voice and data communication, smoother video streaming, and faster downloads/uploads.
