Terminal Relay Sharing for Higher-Quality 6G Downlink Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The technical specifications do not specify a technique for using short range communication to assist communication between a network (base station) and terminals, which is required for higher quality communication in NR successor systems like 6G.
Innovation Solution
A terminal is equipped with a reception unit to receive a downlink signal from a base station through coordination with another terminal and a communication unit to share this signal using short range communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional communication methods are used between base station and terminals, then the communication system is simple and well-defined, but the communication quality cannot meet the requirements of NR successor systems (6G) which need higher quality communication
Solution Approach 1:
The patent introduces a terminal as an intermediary device that receives downlink signals from the base station and shares them with other terminals through short-range communication. This intermediary approach enables higher communication quality by allowing terminals to assist each other in receiving and transmitting signals, thereby meeting the stringent requirements of 6G systems without requiring complete redesign of the base station architecture.
Solution Approach 2:
The patent segments the communication function by separating the downlink signal reception (performed by one terminal) from the signal sharing and distribution (performed through short-range communication between terminals). This segmentation allows the system to achieve high communication quality through coordinated terminal operations while keeping the base station relatively simple.
2Reliability
If short range communication is not used, then the system structure is simple and specifications are clear, but the communication quality and data transmission rate cannot satisfy 6G requirements
Solution Approach 1:
The patent makes terminals multi-functional by enabling them to perform both conventional cellular communication (receiving downlink signals from base station) and short-range communication (sharing signals with other terminals). This multi-functionality allows the system to adapt to varying quality requirements and provide enhanced communication performance when needed, while maintaining compatibility with existing infrastructure.
Solution Approach 2:
The patent introduces dynamic signal sharing where terminals can selectively share downlink signals with other terminals based on communication requirements. This dynamic approach allows the system to flexibly adjust communication quality and data transmission rates according to specific scenarios, enabling the system to meet 6G requirements while maintaining operational flexibility.
3Reliability
If terminal coordination for downlink signal reception is implemented, then communication quality improves, but the coordination complexity and device complexity increase
Solution Approach 1:
The patent implements self-service coordination where terminals autonomously perform signal sharing and coordination functions using their own short-range communication capabilities. Rather than requiring complex centralized control from the base station, terminals self-organize to share downlink signals, thereby improving communication quality while limiting the increase in overall system complexity to only the terminal devices involved in coordination.

AI summary
A terminal includes: a reception unit configured to receive a downlink signal from a base station or a network through coordination with another terminal; and a communication unit configured to receive, from the another terminal, a signal for sharing the downlink signal by using short range communication.
