Telecom Node Transmission Mode Selection for Energy Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks lack an intelligent decision-making process to optimize the use of MIMO and SIMO transmission modes, leading to inefficient energy consumption and increased costs, as they primarily rely on cell load without considering additional user information.
Innovation Solution
A method that determines transmission modes based on the evaluation of application and device awareness, using thresholds to select between SIMO and MIMO configurations, taking into account the required throughput and applying weighting factors for more accurate energy management.

1Productivity
If MIMO transmission mode is used to achieve high throughput, then user data rate is improved, but energy consumption increases
Solution Approach 1:
The system dynamically switches between MIMO and SIMO transmission modes based on real-time evaluation of application requirements and device capabilities. The transmission mode is not fixed but adapts to changing conditions, enabling the network to optimize the trade-off between throughput and energy consumption by selecting the appropriate mode for each user and application scenario
Solution Approach 2:
The invention changes the operational parameters of the transmission system by adjusting the transmission mode (MIMO/SIMO) based on evaluated conditions such as application throughput requirements, device antenna capabilities, and channel conditions. This parameter adjustment allows the system to achieve high throughput when needed while conserving energy when standard transmission suffices
2Reliability
If MIMO mode is activated for all users to ensure high performance, then user experience is improved, but operational costs increase
Solution Approach 1:
The system applies different transmission modes to different users and applications based on their specific requirements. Instead of uniformly applying MIMO to all users, the invention evaluates each user's application needs and device capabilities, applying MIMO only where it provides necessary performance benefits, thereby optimizing the balance between user experience and operational cost
3Device complexity
If basic cell load-based decisions are used for transmission mode selection, then system complexity is reduced, but optimization capability is insufficient
Solution Approach 1:
The system implements a feedback mechanism that collects information about application requirements, device capabilities, and current transmission performance. This feedback is used to continuously evaluate and adjust transmission mode decisions, enabling sophisticated optimization while maintaining manageable system complexity through structured evaluation processes

AI summary
A method of determining a transmission mode configuration for a cell of a node of a telecommunication network, the node configured to serve a plurality of user devices within the cell, wherein the determination is based on evaluation of at least one condition associated with one or more applications running at one or more user devices served by the cell, the evaluation being against a specific transmission mode configuration.
