User Equipment Grouping for Cooperative Wireless Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing density of user equipment and the use of high spectrum frequencies like mmW and THz lead to limited communication range and coverage in wireless networks, with communication occurring primarily through point-to-point connections without cooperation among nearby devices.
Innovation Solution
User equipment forms groups to facilitate cooperative communication, with active devices connected to the network and passive devices communicating indirectly through device-to-device links, utilizing a primary user equipment to manage group membership, data transfer, and control channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If point-to-point connections are used between user equipment and base station, then device complexity is reduced, but communication range and reliability deteriorate due to limited coverage at high frequencies
Solution Approach 1:
The patent introduces intermediate user equipment devices that act as relays between disconnected user equipment and the base station. These intermediary devices receive configuration messages from the base station and forward them to disconnected devices, enabling indirect communication paths that extend coverage range while maintaining system reliability without significantly increasing device complexity.
2Quantity of substance
If user equipment density increases, then network capacity improves, but communication reliability deteriorates due to signal loss at high frequencies
Solution Approach 1:
The patent merges multiple user equipment devices into cooperative groups where connected devices work together to support disconnected devices. By combining the resources and capabilities of multiple devices within a group, the system maintains communication reliability even as overall density increases and signal loss becomes more prevalent at high frequencies.
3Reliability
If cooperative communication is implemented among user equipment groups, then communication range and reliability improve, but device complexity increases due to group management requirements
Solution Approach 1:
The patent segments the network into discrete user equipment groups with clearly defined roles (connected and disconnected members). Each group is managed independently with a primary connected device handling coordination tasks. This segmentation approach allows cooperative communication to improve reliability while containing complexity within manageable group boundaries rather than requiring system-wide complexity.
Data Source
AI summary
User equipment in close proximity may transfer data and control information. For example, the user equipment may exchange data or data sets between each other. Each user equipment can receive and transmit data using radio access technologies. A group of user equipments may include active user equipment and passive user equipment. Active user equipment connects with one or more base stations and transfers data on a wireless communication network via the base station. The active user equipment may communicate with other active user equipment and passive user equipment. Passive user equipment may not connect to any base station and/or the wireless communication network and may communicate with other passive user equipment and active user equipment (e.g., via a sidelink, peer-to-peer, or device-to-device channel).
