Network-Controlled Repeater Beam Scheduling for 5G Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of 5G systems faces challenges in enhancing cell coverage due to the use of legacy RF repeaters, which fail to dynamically adjust beam directions and widths, leading to reduced network throughput and increased interference.
Innovation Solution
A network-controlled repeater (NCR) scheme is introduced, where a network device transmits indication information to a repeater to control access, backhaul, and control link beams, enabling dynamic beam matching with terminal equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a legacy RF repeater is used to amplify and forward signals in a 5G system, then cell coverage can be enhanced, but the repeater cannot dynamically adjust beam directions and widths, causing mismatch with terminal equipment positions and reducing network throughput
Solution Approach 1:
The patent introduces a network-controlled repeater that dynamically adjusts its beam directions and widths based on real-time positioning information of terminal equipment. The repeater receives control signals from the network device that indicate beam parameters, allowing it to adapt its beamforming characteristics dynamically rather than using fixed wide beams, thus maintaining both coverage area and network throughput.
Solution Approach 2:
The system implements a feedback mechanism where the network device monitors the positions of terminal equipment and sends control signals to the repeater to adjust beam parameters accordingly. This closed-loop control ensures that the repeater's beams are continuously optimized to match the current spatial distribution of terminals, resolving the contradiction between maintaining coverage and maximizing throughput.
2Reliability
If a legacy RF repeater with wide fixed beams is used, then signal amplification can be achieved, but significant interference is caused to other devices within a larger range, increasing noise and interference levels of the system
Solution Approach 1:
The patent enables the repeater to transmit signals with localized beam characteristics by dynamically adjusting beam directions and widths. Instead of using wide fixed beams that cover large areas and cause interference to multiple devices, the repeater concentrates its amplification effort in specific directional sectors where terminal equipment is located, thereby maintaining signal amplification effectiveness while reducing interference to other devices outside these targeted sectors.
3Ease of manufacture
If a legacy RF repeater is deployed without network control, then deployment is simple, but the amplification and forwarding effect is not ideal and cannot adapt to dynamic changes in terminal positions
Solution Approach 1:
The patent introduces a network device as an intermediary that coordinates between the repeater and terminal equipment. The network device receives positioning information from terminals, determines optimal beam parameters, and sends control signals to the repeater. This intermediary layer enables the repeater to adapt to dynamic terminal positions without requiring complex autonomous decision-making capabilities in the repeater itself, thus maintaining deployment simplicity while achieving adaptability.
