Signal Forwarding Device Selective Uplink Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional repeaters in communication systems cause signal interference by amplifying all uplink signals and fail to accurately monitor specific user equipment, leading to inaccurate traffic statistics and affected signal quality.
Innovation Solution
A signal processing method and device where the base station sends indication information to signal forwarding devices to perform signal quality measurements on target user equipment, allowing the base station to select the optimal access device for uplink signals and reduce interference by selectively forwarding signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the repeater amplifies all uplink signals, then the coverage area is extended, but signal interference increases and signal quality deteriorates
Solution Approach 1:
The patent segments the uplink signal processing by introducing a signal forwarding device that selectively forwards only specific UE signals to the base station, rather than amplifying all uplink signals. This segmentation allows the system to extend coverage while avoiding interference from unnecessary signal amplification.
Solution Approach 2:
The signal forwarding device implements local quality control by measuring signal quality metrics (RSRP, SINR) and selectively forwarding signals based on quality thresholds. This ensures that only high-quality signals are forwarded, maintaining signal quality while extending coverage to specific local areas.
2Device complexity
If the repeater performs transparent transmission, then the structure remains simple and cost-effective, but the base station cannot identify specific user equipment and accurately monitor traffic
Solution Approach 1:
The signal forwarding device acts as an intermediary between the UE and base station. It maintains the simple repeater structure while adding the capability to measure and report UE signal quality metrics to the base station, enabling UE identification and monitoring without significantly increasing device complexity.
Solution Approach 2:
The signal forwarding device implements feedback mechanisms by measuring signal quality metrics and reporting them to the base station. This feedback enables the base station to identify specific UEs and monitor traffic accurately, while the forwarding device itself remains relatively simple in structure.
3Area of stationary object
If all uplink signals are amplified by the repeater, then coverage is improved, but system performance deteriorates due to signal interference
Solution Approach 1:
The signal forwarding device applies partial action by selectively forwarding only specific UE signals that meet quality criteria, rather than amplifying all uplink signals. This partial forwarding approach maintains coverage improvement while avoiding the performance degradation caused by interference from unnecessary signal amplification.

AI summary
Embodiments of this application provide a signal processing method, a device, and a base station, and relate to the communication field. The method includes: obtaining first indication information, where the first indication information includes a measurement parameter; performing, by a signal forwarding device based on the measurement parameter, signal quality measurement on a received first uplink signal sent by a target user terminal UE; sending a signal quality measurement result to a base station; if obtaining second indication information sent by the base station, receiving a second uplink signal sent by the target UE, and forwarding the second uplink signal to the base station, where the second indication information is sent by the base station to the signal forwarding device, after the base station determines, based on the signal quality measurement result, to determine to allocate the target UE to the signal forwarding device as subordinate UE. Based on this application, the base station can selectively allocate corresponding UE to the signal forwarding device, so that signal interference is effectively reduced, thereby improving signal quality and overall performance of a system.
