Master UE Device Coordinating D2D Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In traditional mobile networks, there is a lack of coordination between UE devices in device-to-device (D2D) communications, leading to interference and inefficiencies as the number of devices increases, particularly in managing wireless channel access and facilitating communication with the network.
Innovation Solution
A master UE device is established to coordinate D2D communications among multiple UE devices, using a D2D coordinator to organize and control D2D communications, including determining helper and target devices to assist with wireless communication and managing wireless channel access to mitigate interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If D2D communication is introduced to allow direct communication between UE devices, then communication efficiency and speed are improved, but interference and coordination difficulties increase as the number of devices increases
Solution Approach 1:
The patent introduces a coordinating entity (base station or master UE device) that acts as an intermediary to manage D2D communications. This coordinator assigns communication resources, manages device pairing, and coordinates transmission timing to enable direct D2D communication while preventing interference through centralized control of the wireless medium
2Device complexity
If all communication goes through base station in traditional mobile network, then coordination and interference management are simplified, but communication overhead and latency increase
Solution Approach 1:
The patent segments communication into two types: traditional network communication through base stations and direct D2D communication between devices. By dividing the communication path, the system maintains centralized coordination for network management while enabling direct peer-to-peer data transfer for time-sensitive applications, thus reducing latency without completely eliminating coordination complexity
3Quantity of substance
If the number of UE devices in mobile network increases, then network capacity and coverage are improved, but D2D communication coordination becomes more difficult
Solution Approach 1:
The coordinating entity serves as a mediator that manages device discovery, pairing, and resource allocation. It maintains a registry of available devices and their capabilities, automatically matching devices for D2D communication based on proximity and service requirements, thereby simplifying coordination even as the network scales to accommodate more devices

AI summary
A master user equipment (UE) device may coordinate device-to-device (D2D) communications amongst a plurality of UE devices. For example, a UE device, which has been designated as a master UE device, may coordinate a D2D communication between a first UE device and a second UE device. The master UE device may be a UE device that obtains an indication that it is a master UE device that is to coordinate D2D communications amongst the plurality of UE devices. In some embodiments, the coordinating the D2D communication may be on behalf of a network and/or to facilitate wireless communication between the network and at least one of the plurality of UE devices.
