UE Relay Selection Using Frequency Lists and QoS Criteria
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in next-generation wireless communications is the efficient selection of relay devices by user equipment (UE) to facilitate high data rate and proximity services, particularly in scenarios where cellular network coverage is limited or unavailable.
Innovation Solution
A system and method for UE to select a relay device based on various criteria, including relay types, frequency lists, quality of service (QoS) parameters, and reference signal received power (RSRP) measurements, with assistance from a wireless communication node, to optimize relay connections.

1Area of stationary object
If UE selects relay devices in limited network coverage scenarios, then network coverage and data rate are improved, but device complexity and selection difficulty increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring frequency lists and relay device information before actual relay selection is needed. The network node provides frequency lists indicating frequencies configured for relay devices, and UEs prepare measurement configurations in advance, so that when relay selection is required, the decision can be made quickly based on pre-gathered information rather than complex real-time analysis.
Solution Approach 2:
The network node acts as an intermediary that facilitates relay device selection by providing frequency lists and relay device information to UEs. This intermediary role simplifies the selection process by filtering and organizing potential relay devices based on network knowledge, reducing the complexity burden on individual UEs while still enabling comprehensive coverage.
2Measurement precision
If multiple frequency lists are configured for relay devices, then relay selection precision is improved, but information processing overhead increases
Solution Approach 1:
The frequency information is segmented into multiple frequency lists, where each list corresponds to different relay devices or relay scenarios. This segmentation allows precise identification of the appropriate relay device by matching the current frequency to the correct list, improving selection precision while organizing information in a structured, manageable way that reduces processing overhead compared to a single large unstructured list.
