Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing repeater systems lack effective beam configuration mechanisms, hindering efficient network coverage expansion.
Innovation Solution
A network-control repeater-Support (ncr-Support) base station provides beam indication information to repeaters, including configuration periodicity, effective time offset, beam index values, and candidate beam sets, allowing repeaters to determine optimal beam indices for alignment with target user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a repeater is used to extend network coverage, then the coverage area is improved, but beam configuration capability deteriorates (no beam configuration mechanism exists)
Solution Approach 1:
The patent introduces an ncr-Support base station as an intermediary that generates and transmits beam indication information to the repeater. This mediator enables the repeater to obtain beam configuration capabilities without modifying the repeater's core architecture, resolving the contradiction between extending coverage and maintaining beam adaptability.
Solution Approach 2:
The beam configuration function is segmented into two parts: the ncr-Support base station handles beam indication information generation and management, while the repeater handles beam selection and application. This segmentation allows the repeater to extend coverage while the base station provides the necessary beam configuration intelligence.
2Measurement precision
If beam indication information is transmitted periodically, then beam alignment accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent implements dynamic beam indication where the periodicity and content of beam indication information are adapted based on channel conditions, traffic patterns, and beam stability. This dynamic approach maintains high beam alignment accuracy while reducing signaling overhead during stable conditions compared to rigid periodic transmission.
Solution Approach 2:
The system changes parameters of beam indication information including periodicity, time offset, and candidate beam set size based on operational conditions. By adjusting these parameters dynamically, the system optimizes the balance between beam alignment precision and signaling resource consumption.
3Adaptability or versatility
If multiple candidate beams are configured, then beam selection flexibility is improved, but configuration complexity increases
Solution Approach 1:
The patent configures a candidate beam set that includes the optimal beam plus several alternative beams with sufficient quality. This partial configuration approach provides beam selection flexibility for handover and failure recovery without configuring all possible beams, thereby limiting configuration complexity while maintaining adequate adaptability.
