Wireless Relay UE Role Control for Dynamic Relay Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack mechanisms for a user equipment (UE) to dynamically accept or reject its role as a relay, and for efficient selection of relay nodes when multiple relays are available, addressing issues of configuration and relay node management.
Innovation Solution
A UE can accept or reject its role as a relay and request release from the relay role through mobile originated or mobile terminated signaling, with assistance information provided to the network for better relay selection and load balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE is configured as a relay node to provide connectivity for remote UEs, then network coverage and connectivity are improved, but the UE loses flexibility to reject the relay role or request release
Solution Approach 1:
The patent implements dynamic relay role management by allowing UEs to transition between relay and non-relay states. The network can configure a UE as a relay node, and the UE can subsequently request release from the relay role or reject the configuration, enabling adaptive and flexible relay deployment based on real-time conditions.
2Reliability
If relay nodes are deployed to extend network coverage, then connectivity is improved, but the complexity of relay node management increases
Solution Approach 1:
The patent introduces feedback mechanisms where relay UEs provide assistance information to the network about their relay status, capabilities, and conditions. This enables the network to make informed decisions about relay selection, configuration, and management, reducing the complexity of handling multiple relay nodes.
Solution Approach 2:
The patent enables UEs to autonomously manage their relay roles by allowing them to request release from relay configuration or reject relay assignments based on their own conditions. This self-service approach reduces network management overhead and simplifies relay node coordination.
3Adaptability or versatility
If multiple relay nodes are available, then connectivity options are improved, but the difficulty of selecting the optimal relay increases
Solution Approach 1:
The patent implements a feedback-based relay selection mechanism where relay UEs provide assistance information including their relay status, capabilities, and operational conditions. The selecting entity uses this feedback information to evaluate and compare multiple relay nodes, making the selection process more systematic and easier to manage.

AI summary
A user device, UE, for a wireless communication system, is described. The UE is to receive a configuration command, the configuration command to cause the UE to act as a relay UE so as to provide functionality to support connectivity to a destination for one or more remote UEs of the wireless communication system. Responsive to receiving the configuration command, the UE is to accept or reject the configuration command.
