Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to measure link quality between a terminal and a sidelink relay in a wireless communication system to support mobility and report information on sidelink discovery messages and data transmission/reception through a sidelink relay.
Innovation Solution
A method and apparatus for a terminal to identify interest in transmitting or receiving sidelink discovery messages or requesting transmission resources, and to report sidelink UE information to a base station, including information on sidelink discovery message transmission and U2N relay communication, with the terminal obtaining measurement configuration information for link quality and reporting to the base station.

Engineering Contradiction Analysis
1Area of stationary object
If a terminal connects to the network through a sidelink relay, then service coverage is extended, but link quality measurement and mobility support become more complex
Solution Approach 1:
The base station acts as an intermediary that receives measurement reports from the terminal via the sidelink relay and processes mobility decisions. The relay UE facilitates measurement reporting by forwarding messages between the terminal and base station, enabling the network to manage connectivity without requiring direct complex measurements between terminal and base station.
Solution Approach 2:
The terminal measures link quality (RSRP, SINR) and reports these values to the base station through the sidelink relay. The base station uses this feedback information to determine whether to switch the terminal from sidelink relay connection to direct connection, enabling dynamic mobility management based on actual link conditions.
2Adaptability or versatility
If the terminal measures link quality through sidelink relay, then mobility support is improved, but power consumption increases
Solution Approach 1:
The terminal performs link quality measurements periodically rather than continuously, reporting measurements to the base station at scheduled intervals. This periodic measurement approach enables mobility support while significantly reducing power consumption compared to continuous monitoring and processing.
3Reliability
If the base station processes sidelink measurement information, then path switch decision is improved, but processing complexity increases
Solution Approach 1:
The base station processes measurement information separately for different terminals and connection types (sidelink relay vs. direct connection). By segmenting the processing tasks and using standardized measurement report formats, the base station can make accurate path switch decisions without requiring complex unified processing algorithms.
