Repeater Beam Configuration via Base Station Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, determining the optimal beam configuration for a repeater to transmit and receive signals to and from a terminal is challenging, especially when a repeater is placed between a base station and a terminal.
Innovation Solution
A method where a base station transmits control information to a repeater, including beam information, and the repeater receives this information to transmit signals to a terminal based on the specified beam configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a repeater is placed between base station and terminal to extend coverage, then signal coverage area is improved, but beam configuration complexity increases
Solution Approach 1:
The repeater serves as an intermediary device between the base station and terminal, receiving control information from the base station and applying beamforming to extend signal coverage to terminals that would otherwise be out of range
Solution Approach 2:
The system changes beam parameters (beam ID, reference signal resources) through control information transmitted from the base station to the repeater, allowing dynamic adjustment of beam configuration to resolve the complexity issue
2Reliability
If beamforming is implemented at the repeater to improve signal quality, then transmission quality is improved, but control overhead increases
Solution Approach 1:
The base station acts as a controller that transmits compact control information (beam ID, reference signal resources) to the repeater, minimizing control overhead while enabling the repeater to implement beamforming for improved transmission quality
3Area of stationary object
If the repeater uses omnidirectional antenna to transmit signals, then coverage area is improved, but beamforming gain is lost
Solution Approach 1:
The repeater dynamically switches between different beam configurations based on control information from the base station, allowing it to adapt between directional beamforming (for gain) and broader coverage patterns as needed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables the repeater to achieve beamforming gain by amplifying and transmitting signals under the control of the base station, improving signal coverage and quality.
Implementation Method 1
determining, by a base station, a beam that a repeater transmits and receive to and from a terminal... the repeater amplifies and transmits a signal or channel provided from the base station to the terminal
