Wireless Repeater Dynamic Forwarding Control via Base Station Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing repeaters in wireless communication systems lack the ability to be controlled by the base station, limiting their flexibility in network deployment and making it difficult to determine the optimal time for uplink and downlink forwarding, especially in TDD systems.
Innovation Solution
The proposed solution involves a repeater that can receive indication information from the network, allowing it to adjust the direction of signal reception and forwarding, as well as the time of uplink and downlink forwarding. This is achieved through the use of reference signal information and time domain resource information, enabling the repeater to operate more flexibly and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If repeaters operate autonomously without base station control, then device complexity is reduced, but adaptability and deployment flexibility are limited
Solution Approach 1:
The repeater dynamically adjusts its operating parameters including uplink/downlink time slots, frequency resources, and beamforming directions based on real-time base station control signals. This enables the repeater to adapt to changing network conditions and deployment scenarios while maintaining manageable complexity through centralized control.
Solution Approach 2:
The base station receives feedback information from the repeater about its operating status, channel conditions, and performance metrics. Based on this feedback, the base station sends control signals to adjust repeater parameters, creating a closed-loop control system that optimizes repeater performance while keeping the repeater itself relatively simple.
2Device complexity
If repeaters use fixed forwarding timing, then device complexity is reduced, but communication efficiency deteriorates in TDD systems
Solution Approach 1:
The repeater implements dynamic forwarding timing adjustment where uplink and downlink forwarding time slots are flexibly configured based on TDD frame structures and traffic conditions. The base station controls the timing parameters through control signals, allowing the repeater to optimize communication efficiency for different service scenarios without complex autonomous timing management.
3Device complexity
If repeaters lack base station control capability, then device complexity is reduced, but coverage enhancement and reliability are limited
Solution Approach 1:
The base station acts as an intermediary that manages and coordinates repeater operations. It sends control signals to configure repeater parameters including reference signal resources, time domain resources, and spatial filters, thereby ensuring reliable and optimized communication without requiring complex autonomous decision-making at the repeater.
