Terminal Downlink Sharing via Short-Range Coordination for 6G
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 necessary for achieving higher quality communication in the NR successor system (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, enabling coordinated communication between the network and terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If short range communication is used to assist communication between base station and terminals, then communication quality is improved, but technical specification completeness deteriorates
Solution Approach 1:
The patent introduces a coordination terminal as an intermediary device that facilitates communication between the base station and other terminals. This coordination terminal receives downlink signals from the base station, processes them locally, and shares processed signals with other terminals through short range communication, thereby improving communication quality while maintaining manageable system complexity through a clearly defined intermediary role.
Solution Approach 2:
The coordination terminal performs self-service by autonomously receiving downlink signals, processing them through local decoding, and sharing the processed signals with other terminals. This self-service capability eliminates the need for complex centralized control mechanisms, allowing the system to improve communication quality while avoiding excessive technical specification complexity.
2Reliability
If downlink signal sharing between terminals is implemented, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The patent segments the communication function by designating a specific coordination terminal to handle signal reception and processing tasks. Instead of requiring all terminals to perform complex signal processing, the system divides the workload: the coordination terminal receives and processes downlink signals, then shares processed results with other terminals. This segmentation improves communication reliability while controlling system complexity through functional specialization.
Solution Approach 2:
The coordination terminal creates copies of the processed downlink signal and distributes these copies to other terminals through short range communication. This copying approach allows multiple terminals to access the same processed information without requiring each terminal to independently process the original signal, thereby improving communication reliability while reducing overall system complexity.

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.
