Enhanced UE Formation for Wireless Cooperation Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in effectively managing and configuring UE cooperation, which is essential for enhancing communication features like coverage, capacity, latency, and reliability, particularly in scenarios like V2X, eMBB, and URLLC, due to complexities in coordinating multiple User Equipments (UEs) for improved communication.
Innovation Solution
The formation of an enhanced UE, where multiple UEs cooperate to assist each other, is managed as a single logical entity, allowing for enhanced capabilities such as increased antennas, transmit power, and processing power, enabling improved communication by treating the group of UEs as a single unit for scheduling and signaling, with capabilities being voluntarily shared and configured through signaling protocols.

Engineering Contradiction Analysis
1Reliability
If multiple UEs are coordinated for cooperation to enhance communication capabilities, then coverage, capacity, latency, and reliability are improved, but device complexity and management difficulty increase
Solution Approach 1:
Multiple UEs are merged into a single enhanced UE entity that is managed by the network as one logical unit. The network device obtains capability information of the enhanced UE formed by multiple UEs and communicates with it as a single entity, combining the resources and capabilities of multiple devices while simplifying network management through unified handling.
Solution Approach 2:
The enhanced UE acts as an intermediary between individual UEs and the network. It consolidates capability information from multiple UEs and presents a unified interface to the network device, mediating the complexity of multi-UE coordination while maintaining simplified network-side management.
2Productivity
If multiple UEs form an enhanced UE with combined capabilities, then communication performance is enhanced, but information management and capability distribution become more complex
Solution Approach 1:
Capability information from multiple individual UEs is merged into a single enhanced UE capability profile. The network device obtains consolidated capability information that represents the combined capabilities of all UEs in the cooperation group, enabling efficient resource allocation and scheduling without managing separate capability sets for each UE.
3Area of stationary object
If UE cooperation is implemented to improve coverage and capacity, then network performance is enhanced, but configuration and management challenges increase
Solution Approach 1:
The enhanced UE autonomously manages its own configuration and operation within the network. Once formed, the enhanced UE self-configures its capabilities and operates independently, reducing the need for manual configuration and simplifying network operations while expanding coverage area through coordinated multi-UE transmission.

AI summary
An enhanced User Equipment (UE) is formed by multiple UEs in a wireless communication network to assist one of the multiple UEs with communications, and involves UE cooperation between the multiple UEs. A capability, or at least one capability, of the enhanced UE is an enhanced capability relative to a capability of the UE that the enhanced UE is to assist. Information that is indicative of the (at least one) capability of the enhanced UE is obtained by a network device, and the network device communicates with the enhanced UE after obtaining the information. From a UE side, information indicative of a capability, or at least one capability, associated with the enhanced UE is transmitted, and the UE communicates with the network device after transmitting the information.
