Wireless Relay Carrier Aggregation Threshold Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for controlling Carrier Aggregation (CA) between wireless relays and User Equipment (UE) based on CA thresholds are neither effective nor efficient, leading to limited resource availability for wireless access points serving additional relays and UEs.
Innovation Solution
A donor base station determines a modified R2UE CA threshold based on its utilization amount and wirelessly transfers this threshold to the wireless relay, allowing the relay to adjust CA configurations for optimal resource allocation, including activation or deactivation of carriers, to manage resource blocks effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If CA is provided to both relays and UEs based on initial CA thresholds, then throughput rate is improved, but resource availability for wireless access points deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of CA thresholds by the donor base station based on real-time resource utilization conditions. The initial CA thresholds configured in the relay are modified dynamically according to current network state, allowing the system to adapt resource allocation between relays and UEs rather than using static threshold values.
Solution Approach 2:
The donor base station monitors its resource utilization and provides feedback by determining modified CA thresholds based on current conditions. This feedback mechanism allows the system to adjust CA configurations in response to changing resource availability, preventing resource exhaustion while maintaining throughput optimization.
2Ease of operation
If CA thresholds are used to control CA between relay and UE, then resource allocation is simplified, but effectiveness and efficiency deteriorate
Solution Approach 1:
The donor base station acts as an intermediary that receives resource utilization information and translates it into modified CA thresholds. This intermediary function bridges the gap between simple threshold-based control and complex resource management needs, maintaining ease of operation while improving control effectiveness through centralized intelligence.
3Area of stationary object
If multiple relays and UEs are served by donor base station, then network coverage is expanded, but resource constraints worsen
Solution Approach 1:
As more relays and UEs are added to expand coverage, the system dynamically adjusts CA thresholds based on real-time resource utilization. This dynamic adaptation allows the network to accommodate additional nodes while automatically managing resource allocation to prevent overload, enabling coverage expansion without proportional resource consumption.

AI summary
A wireless communication network controls Carrier Aggregation (CA), a donor base station wirelessly serves a wireless relay and the donor base station and the wireless relay wirelessly serve User Equipment (UE). The wireless relay wirelessly exchanges user data with a UE using CA based on an initial relay to UE (R2UE) CA threshold. The donor base station determines a donor base station utilization amount and processes the donor base station utilization amount to determine a modified R2UE CA threshold. The donor base station wirelessly transfers an instruction to the wireless relay indicating the modified R2UE CA threshold. The wireless relay wirelessly receives the modified R2UE CA threshold and exchanges additional user data with the UE using CA based on the modified R2UE CA threshold.
