Relay UE Multicast Grouping for Transmission Resource Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In UE-to-network relay systems, relay UE is unaware of the information transmitted between the network device and remote UE, leading to inefficient use of transmission resources and increased time and signaling for data transmission.
Innovation Solution
Implementing a communication method where a first terminal device, aware of the information, establishes multicast paths and sends data to multiple second terminal devices using a single transmission resource, reducing the need for unicast transmissions and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If unicast mode is used for data transmission between network device and remote UE through relay UE, then each terminal device can receive dedicated data, but transmission resources are wasted and transmission time increases
Solution Approach 1:
The patent merges multiple unicast transmission paths into a single multicast path. The network device sends data to multiple remote UEs simultaneously through a single multicast transmission instead of separate unicast transmissions, thereby reducing transmission resources and improving efficiency
Solution Approach 2:
The relay UE is enhanced to perform multiple functions: it not only forwards data but also identifies services, allocates group identifiers, and manages multicast paths. This multi-functionality enables the relay UE to optimize resource usage by coordinating multicast transmissions
2Device complexity
If relay UE forwards data without awareness of transmitted information, then implementation is simple, but transmission resources cannot be optimized
Solution Approach 1:
The relay UE performs self-service by autonomously identifying services, allocating group identifiers, and establishing multicast paths without requiring complex network device intervention. This enables the relay UE to optimize resource usage independently while maintaining implementation feasibility
3Quantity of substance
If multicast mode is implemented without service identification capability at relay UE, then resource savings are achieved, but the relay UE cannot manage multiple services effectively
Solution Approach 1:
The patent segments service management by introducing service identification at the relay UE. Each service is identified and managed separately through service-specific group identifiers, enabling the relay UE to handle multiple services effectively while maintaining resource efficiency through multicast transmission
