Multi-UE Aggregation Signaling for Assisted Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-user equipment (UE) aggregation transmission systems face challenges in selecting and configuring other UEs to assist in data transmission, particularly when a UE has a large amount of data to transmit, as current methods do not allow for random selection of assisting UEs by the network device.
Innovation Solution
A method for determining UE identification information of a second UE to assist a first UE in data transmission, involving selection from multiple UEs based on pre-configured associations, operation administration and maintenance (OAM) configurations, or UE-to-UE associations, with support for IDLE or INACTIVE state UEs entering a connected state, and configuring end-to-end bearers and mapping relationships through RRC or MAC signaling.

Engineering Contradiction Analysis
1Productivity
If other UEs are used to assist in data transmission, then data transmission capability is improved, but configuration complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing association relationships between UEs before the actual data transmission occurs. The network device pre-configures which UEs can assist each other, and UEs pre-exchange capability information, so that when data transmission is needed, the assisting UEs are already identified and ready for configuration, reducing real-time configuration complexity.
Solution Approach 2:
The patent implements feedback mechanisms where UEs report their capabilities and association relationships to the network device, and the network device provides feedback configuration instructions to selected assisting UEs. This feedback loop enables dynamic adaptation while maintaining manageable configuration complexity through structured information exchange.
2Reliability
If specific other UEs are used for assisting transmission, then transmission reliability is improved, but system flexibility deteriorates
Solution Approach 1:
The patent applies dynamics by making the association relationships between UEs configurable and changeable. The network device can dynamically select which pre-associated UEs to activate for a given transmission task based on current network conditions, allowing the system to adapt between reliable fixed associations and flexible dynamic reconfiguration as needed.
Solution Approach 2:
The patent segments the UE assistance function into separate association relationships that can be independently configured. Instead of a monolithic fixed pairing, the system divides potential assisting relationships into discrete, manageable associations that can be selectively activated, allowing both reliability through specific pairings and flexibility through selective activation.
3Productivity
If multiple second UEs exist, then transmission capacity is improved, but selection difficulty increases
Solution Approach 1:
The patent applies preliminary action by having UEs pre-exchange and store association relationship information and capability data before transmission needs arise. When multiple UEs are available for assistance, the network device can quickly reference pre-configured associations rather than performing complex real-time evaluation, significantly reducing selection difficulty while maintaining the ability to utilize multiple UEs for high capacity transmission.
