Relay Node Resource Reporting via Donor Base Station Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, relay nodes face challenges in accurately reporting their resource status due to limited knowledge about their backhaul link resources, which affects mobility load balancing and resource management across neighboring base stations.
Innovation Solution
A method where a donor base station intercepts and modifies resource status reports from relay nodes by incorporating information not available at the relay node, such as backhaul link details, to provide a more accurate and complete resource status update to target base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If relay nodes generate resource status reports independently, then reporting simplicity is improved, but reporting accuracy deteriorates due to limited knowledge about backhaul link resources
Solution Approach 1:
The donor base station acts as an intermediary that receives resource status reports from relay nodes, enriches them with backhaul link resource information, and forwards the enhanced reports to target base stations. This mediator approach allows relay nodes to maintain simple independent reporting while achieving accurate comprehensive resource status through the donor base station's supplementation of backhaul link details.
2Quantity of substance
If relay nodes include all parameters in reports, then completeness is improved, but device complexity increases due to need for backhaul link information
Solution Approach 1:
The donor base station serves as an intermediary that receives incomplete resource status reports from relay nodes, adds the missing backhaul link resource parameters, and forwards the complete enhanced reports to target base stations. This approach achieves full report completeness without increasing the relay node's processing complexity, as the donor base station performs the parameter supplementation.
Solution Approach 2:
The resource status reporting function is segmented into two parts: the relay node generates the access link resource status portion, while the donor base station generates and adds the backhaul link resource status portion. This segmentation allows each entity to handle only the parameters it can observe, avoiding the need for relay nodes to process information beyond their knowledge scope.
3Reliability
If relay nodes report with full information, then resource management quality is improved, but information availability at relay node is insufficient
Solution Approach 1:
The donor base station acts as an intermediary that has access to both the relay node's report and the backhaul link resource information. It combines these information sources to create a complete resource status report, thereby recovering the lost backhaul link information and enabling high-quality resource management at target base stations.

AI summary
Certain aspects of the present disclosure provide techniques and apparatuses for wireless communications. The techniques generally include intercepting a report message from a relay node destined for a target base station, modifying the report message based on information not available at the relay node, and sending the modified report message to the target base station.
