Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telecommunications systems prioritize spatial multiplexing single layer (SMSL) connections for user equipment (UEs) despite marginal throughput gains and battery life impact on mobile devices, while neglecting the power consumption and mobility of mobile devices.
Innovation Solution
Classify UEs as stationary or mobile devices and configure them to use spatial multiplexing single layer (SMSL) or single input, single output (SISO) connections accordingly, optimizing network and UE parameters to balance throughput and battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spatial multiplexing single layer (SMSL) connections are used for all user equipment, then throughput is improved, but battery life deteriorates for mobile devices
Solution Approach 1:
The patent segments user equipment into two distinct categories: stationary devices and mobile devices. This segmentation allows the network to apply different connection configurations (SMSL for stationary, SISO for mobile) based on device type, thereby optimizing throughput for stationary devices while conserving battery life for mobile devices.
Solution Approach 2:
The patent applies local quality by configuring different transmission modes for different device types. Stationary devices receive SMSL configuration for maximum throughput, while mobile devices receive SISO configuration for lower power consumption. This localized optimization ensures each device type gets the most appropriate configuration for its specific needs.
2Productivity
If spatial multiplexing single layer (SMSL) connections are used, then network capacity is improved, but device complexity increases
Solution Approach 1:
By segmenting UEs into stationary and mobile categories, the patent simplifies the configuration process. Instead of evaluating multiple factors for each individual UE, the network can apply predetermined configurations based on device type, reducing the complexity of connection management while maintaining high network capacity through appropriate SMSL deployment for stationary devices.
3Productivity
If dual-layer connections are maintained for all UEs, then throughput is maximized, but reliability deteriorates when channel conditions are poor
Solution Approach 1:
The patent implements a dynamic approach by initially attempting dual-layer connections for all UEs, then transitioning to appropriate single-layer configurations (SMSL or SISO) based on device type and performance. This dynamic adaptation allows the system to maximize throughput when conditions permit while ensuring reliability by switching to more robust single-layer configurations when needed.

AI summary
Systems and methods are provided for establishing single-layer connections between user equipment (UEs) and a telecommunications network based on the UEs' device types. UEs are classified as either stationary devices or mobile devices based on device information, such as subscriber identity module (SIM) profiles. When a multi-layer connection should not be maintained with a UE, if the UE is classified as a stationary device, the telecommunications network establishes a spatial multiplexing single layer (SMSL) connection with the UE. If the UE is classified as a mobile device, the telecommunications network establishes a single input, single output (SISO) connection with the UE.
