Beam Alignment Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 17966506 titled 'Beam Alignment Method and Apparatus
Simplified Explanation
The abstract describes a network device that receives a signal from a terminal device and calculates a conjugate phase to determine a narrow beam in the opposite direction of the signal. The network device then communicates with the terminal device using this narrow beam.
- The network device receives an uplink signal from a terminal device.
- It calculates a conjugate phase corresponding to the received signal.
- Based on the conjugate phase, the network device determines a narrow beam with an opposite direction of arrival to the signal.
- This narrow beam is used as a target transmit beam for communication between the network device and the terminal device.
Potential Applications
- Wireless communication systems
- Cellular networks
- Satellite communication
- Internet of Things (IoT) devices
Problems Solved
- Interference reduction: By using a narrow beam in the opposite direction of the signal, the network device can minimize interference from other signals or noise.
- Improved signal quality: The use of a target transmit beam can enhance the signal quality between the network device and the terminal device.
Benefits
- Enhanced communication performance: By aligning the transmit beam with the terminal device, the network device can establish a more reliable and efficient communication link.
- Reduced interference: The use of a narrow beam helps to minimize interference from other devices or signals, leading to improved overall network performance.
Original Abstract Submitted
A network device receives a first uplink signal from a terminal device; the network device calculates a conjugate phase corresponding to the first uplink signal, and determines, based on the conjugate phase, a narrow beam whose direction of arrival is opposite to a direction of arrival of the first uplink signal as a target transmit beam aligned between the network device and the terminal device; and the network device communicates with the terminal device by using the target transmit beam.
