Multi-Path Sidelink Configuration for Service-Aware UE Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing multiple paths for communication between user equipment (UEs) in wireless communications systems is challenging, particularly in determining appropriate communication parameters for multi-path operations.
Innovation Solution
A first UE establishes an end-to-end link with a second UE, transmitting a configuration for a second path based on service information, allowing traffic to be communicated via the first or second path according to the indicated configuration, which includes determining communication parameters using a multi-path rule at the ProSe or RRC layer.

Engineering Contradiction Analysis
1Reliability
If multiple paths are established for communication between UEs, then communication reliability and efficiency are improved, but path management complexity increases
Solution Approach 1:
The network entity acts as an intermediary to manage and coordinate multiple communication paths between UEs. The network entity receives path configuration requests, determines appropriate path configurations based on service requirements, and provides routing instructions to UEs, thereby simplifying path management at the UE level while maintaining multiple paths for improved reliability
Solution Approach 2:
The system dynamically adjusts communication parameters such as path configuration, resource allocation, and routing decisions based on service requirements and network conditions. By changing these parameters adaptively, the system can optimize the use of multiple paths while managing complexity through parameter-based control mechanisms
2Manufacturing precision
If communication parameters are determined for multi-path operations, then service-specific constraints are satisfied, but determination complexity increases
Solution Approach 1:
The network entity pre-determines communication parameters and path configurations based on service requirements before actual data transmission begins. By performing parameter determination in advance, the system ensures service-specific constraints are met while reducing the complexity of real-time parameter decisions during communication
Solution Approach 2:
UEs are equipped with capabilities to autonomously determine and configure communication parameters for multi-path operations based on received routing instructions and service information. This self-service approach reduces the burden on the network entity while ensuring service constraints are satisfied through UE-side parameter determination

AI summary
Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish an end-to-end link with a second UE for communicating traffic associated with a service, the end-to-end link including a first path. The first UE may transmit, via the end-to-end link, an indication of a configuration for a second path between the first UE and the second UE, where the configuration for the second path is based on service information associated with the service. The first UE may communicate, with the second UE, traffic associated with the service via the first path or the second path based on transmitting the indication of the configuration for the second path.
