Relay Transmission Mode for Wireless Energy Efficiency
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, causing congestion and throughput degradation, especially with the increasing popularity of mobile internet and the need to extend device battery life.
Innovation Solution
The implementation of a relay transmission mode in multiple device coordination (MDC) systems, where a coordinating device identifies and selects a relay node from associated devices to establish a single radio resource connection with a base station, optimizing energy efficiency by reducing power consumption and improving throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple devices establish individual radio resource connections with the network, then each device can communicate independently, but transmission efficiency deteriorates and energy consumption increases due to limited radio resources and congestion
Solution Approach 1:
The patent merges multiple device connections into a single radio resource connection through relay transmission mode. Instead of each device establishing individual RRC connections with the base station, multiple devices share one connection managed by a coordinating device, reducing control channel overhead and improving transmission efficiency while lowering energy consumption
Solution Approach 2:
The relay transmission mode enables a single RRC connection to serve multiple devices simultaneously. The coordinating device acts as a universal interface for the group, allowing multiple devices to communicate through shared resources without requiring separate connection management for each device
2Reliability
If each device maintains active communication with the network, then real-time communication is possible, but battery life decreases due to continuous power consumption and control channel monitoring
Solution Approach 1:
The patent extracts the communication management function from individual devices and consolidates it at the relay node. Non-coordinating devices can remain in sleep state longer since they don't need to independently monitor control channels, while the coordinating device maintains the single RRC connection, ensuring communication availability while extending battery life
Solution Approach 2:
The coordinating device serves as an intermediary between the network and multiple devices. It maintains the RRC connection with the base station and manages data transmission for the entire group, allowing other devices to conserve energy by sleeping longer while still maintaining reliable communication through the intermediary

AI summary
Techniques for energy efficiency utilizing the relay transmission mode of multiple device coordination (MDC) in a wireless communication system are described. For example, a method includes identifying, by a coordinating device including a processor, one or more devices associated with a same entity as the coordinating device, wherein the coordinating device and the one or more devices are part of a set of devices. The method also includes coordinating, by the coordinating device, with the one or more devices to enable a single radio resource connection (RRC) between the set of devices and a base station. The coordinating can include selecting a relay node device, from among the set of devices, to relay data transmitted from the set of devices during a relay transmission mode. The data is relayed to the base station using the single RRC, which is established through the relay node device.
