Relay User Equipment Preferential Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, relay wireless devices often lack sufficient resources or priority to effectively improve network conditions for other devices they are relaying, especially in crowded areas or at the edge of a base station's coverage.
Innovation Solution
A method where a donor access node configures a user equipment (UE) acting as a relay with preferential treatment, including carrier aggregation, beamforming, higher scheduling priority, and increased air-interface resources, to enhance network performance compared to non-relaying UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If relay wireless devices are used to improve coverage and service for devices at the edge of coverage area or in crowded areas, then network coverage and throughput for relayed devices are improved, but the relay wireless device itself does not receive enough resources or priority from the donor access node to adequately service the relayed devices
Solution Approach 1:
The patent applies local quality by providing differentiated resource allocation and scheduling priority specifically to relay wireless devices compared to non-relay devices. The donor access node identifies relay devices and grants them enhanced resources including dedicated physical downlink control channels (PDCCH), increased scheduling priority, and preferential treatment for random access preamble transmission, ensuring that the relay function receives sufficient resources to adequately service relayed devices.
Solution Approach 2:
The patent changes key network parameters including scheduling priority levels, resource allocation ratios, and control channel configurations based on the relay status of wireless devices. By dynamically adjusting these parameters according to whether a device is functioning as a relay, the system optimizes overall network performance and ensures relay devices have adequate capacity to service relayed devices effectively.
2Ease of operation
If relay wireless devices operate with standard resource allocation, then device complexity is reduced and ease of operation is maintained, but network performance and service quality for relayed devices deteriorate due to insufficient resources
Solution Approach 1:
The patent implements self-service mechanisms where relay wireless devices automatically indicate their relay status to the donor access node and receive appropriate resource allocation without manual configuration. The system autonomously identifies relay devices based on their operational behavior and grants them enhanced resources and priority, maintaining ease of operation while ensuring reliable service quality for relayed devices through automatic resource optimization.

AI summary
When a wireless device is configured to function as a relay for a donor access node, the donor access node is configured such that the relaying wireless device is given preferential treatment when compared to non-relaying wireless devices. The communication network and/or donor access node can be configured to provide improved RF conditions, higher throughput, lower latency, etc. to a relaying wireless device than is provided to non-relay wireless devices.
