Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately and efficiently performing wireless signal transmission/reception procedures, particularly in supporting multiple wireless communication paths and handling configuration failures in indirect paths.
Innovation Solution
A method for configuring multiple wireless communication paths by a first user equipment (UE) in a wireless communication system, involving procedures for configuring a direct path, receiving configuration information for an indirect path, and performing bearer suspension based on failure information included in sidelink messages from a relay UE.

Engineering Contradiction Analysis
1Reliability
If multiple wireless communication paths (direct and indirect) are configured to improve communication reliability, then the system complexity increases due to path management and failure handling
Solution Approach 1:
The communication path is segmented into direct path and indirect path components, allowing independent configuration and management of each path type. The indirect path is further segmented into relay UE selection, relay connection establishment, and bearer configuration stages, simplifying the overall management complexity.
Solution Approach 2:
A relay UE acts as an intermediary node between the remote UE and the network, enabling indirect communication when direct paths are unavailable. The relay UE manages the complexity of path switching by handling bearer suspension and resumption procedures locally, reducing the management burden on the remote UE and network.
2Adaptability or versatility
If configuration information for indirect paths is received and managed, then communication flexibility improves, but the time required for configuration and failure handling increases
Solution Approach 1:
Configuration information for indirect paths is received and prepared in advance through RRC signaling before actual communication needs arise. The relay UE pre-configures bearers and establishes connectivity options, so that when direct paths fail, the switch to indirect paths can occur rapidly without extensive real-time configuration delays.
Solution Approach 2:
The system implements feedback mechanisms where the relay UE monitors the status of indirect path configurations and reports back to the remote UE and network. This feedback enables dynamic adjustment of configuration parameters and rapid detection of configuration failures, reducing the time required for reconfiguration and improving overall adaptability.
3Use of energy by moving object
If bearer suspension is performed based on failure information to maintain resource efficiency, then energy consumption decreases, but communication latency may increase due to suspension and resumption procedures
Solution Approach 1:
The bearer configuration is made dynamic, allowing the system to suspend bearers when indirect paths are not actively needed and resume them quickly when required. The relay UE dynamically adjusts bearer states based on real-time communication demands and path availability, optimizing the balance between energy consumption and latency by keeping critical bearers active while suspending non-critical ones.

AI summary
In the present disclosure, as device may perform a procedure for configuring a direct path connected to a network, receive, in a radio resource control (RRC) connected state in which the direct path is configured, configuration information regarding an indirect path between the device and the network, and receive a sidelink message from another device configured as a relay device for the indirect path, wherein, based on failure information being included in the sidelink message from the another device, the device may perform bearer suspension for a first bearer related to the indirect path.
