Multiple Device Coordination in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the use of multiple devices by a single user leads to transmission and energy inefficiencies due to limited radio resources, resulting in restricted system capacity and congestion, which exacerbates battery life issues and throughput degradation.
Innovation Solution
Implementing a method for multiple device coordination (MDC) where a coordinating device identifies and manages a shared radio connection among devices associated with the same entity, enabling efficient resource sharing, reduced mobility management, and power consumption, while maintaining transparency to the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are used by a single user, then device functionality and versatility are improved, but transmission efficiency and energy consumption deteriorate due to limited radio resources
Solution Approach 1:
The patent merges multiple devices into a single coordinated entity by establishing one radio connection that serves all devices associated with the same entity. The coordinating device aggregates data from multiple non-coordinating devices and transmits through a single radio interface, combining the functionality of multiple devices while using only one radio connection, thereby reducing energy consumption and improving transmission efficiency.
2Ease of operation
If multiple devices establish individual radio connections, then device independence and ease of operation are improved, but system capacity and resource utilization deteriorate
Solution Approach 1:
The patent segments the system into coordinating devices and non-coordinating devices, where each device maintains its operational independence and functionality. However, at the radio connection level, these segmented devices are grouped under a single coordinating device that manages one shared radio connection, allowing device independence to be preserved while optimizing system capacity through resource sharing.
3Reliability
If each device maintains separate radio connections, then transmission reliability for individual devices is improved, but overall transmission efficiency and spectrum utilization deteriorate
Solution Approach 1:
The coordinating device acts as an intermediary between multiple non-coordinating devices and the network. It receives data from non-coordinating devices, manages the single radio connection, and handles transmission to the network. This intermediary approach maintains transmission reliability by providing centralized management and error handling, while simultaneously improving spectrum efficiency through consolidated resource usage.
4Ease of operation
If multiple radio connections are maintained, then individual device mobility management is simplified, but overall mobility management complexity and resource overhead increase
Solution Approach 1:
The single radio connection established by the coordinating device serves multiple functions simultaneously: it handles data transmission for all associated devices, manages mobility for the entire group, and provides resource allocation for multiple devices. This multi-functional approach simplifies mobility management by having one connection handle all tasks, reducing the overall complexity compared to managing separate connections for each device.

AI summary
Multiple device coordination (MDC) in a wireless communication system is described. For example, a method includes identifying, by a coordinating device associated with an entity, one or more non-coordinating devices of a network and associated with the same entity. The method also includes coordinating a single, shared radio connection to which the coordinating device and the one or more non-coordinating devices are communicatively coupled. In some instances, coordination is performed via initializing, management and/or transmission stages. For example, from a set of candidate devices, a coordinating device and the non-coordinating devices are determined during the initialization stage. The coordinating device can be selected based on any number of different factors including, but not limited to, proximity to base station, transceiver power, resources, screen size and/or based on a selection made by the entity.
