Solution Overview

Problem

Future wireless communications systems face challenges in managing overheating in user equipment (UE) due to increased processing requirements, which can lead to heat dissipation issues caused by packaging limitations.

Innovation Solution

The UE detects overheating conditions and dynamically updates its capability by reducing operating capabilities, such as data rate or number of carriers, and transfers this information to the network. The UE then applies the reduced capabilities to the connection, which helps in reducing heat dissipation requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If UE operates with higher capabilities (higher data rate, more carriers, more antennas), then communication performance is improved, but heat generation increases due to higher processing requirements

Engineering Contradiction:
Improvecommunication performanceVSAvoidheat generation
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

The UE dynamically adjusts its operating capabilities based on thermal conditions. The system transitions from static capability configuration to dynamic capability modification, where the UE can switch between different capability sets (first and second sets) depending on whether overheating is detected, allowing real-time adaptation between performance and thermal management

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes operational parameters such as data rate, number of carriers, and antenna configuration based on thermal state. By modifying these parameters dynamically, the system resolves the contradiction between achieving high communication performance and managing heat generation through parameter adaptation

Inventive Principle:
Principle #35Parameter changes

2Temperature

If UE reduces operating capabilities to manage heat, then heat dissipation is improved, but communication performance deteriorates

Engineering Contradiction:
Improveheat dissipationVSAvoidcommunication performance
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The system implements feedback mechanisms where the UE monitors its thermal state and provides information to the network about its capability status. This feedback loop allows the network to adjust resource allocation and configuration in response to UE thermal conditions, enabling performance recovery when temperature is managed

Inventive Principle:
Principle #23Feedback

3Temperature

If UE disconnects from network to manage overheating, then heat dissipation is improved, but service continuity is worsened

Engineering Contradiction:
Improveheat dissipationVSAvoidservice continuity
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The network acts as an intermediary that facilitates capability negotiation between UE and core network. Through this intermediary, the UE can reduce capabilities locally without disconnecting, as the network coordinates the capability change and maintains the connection, thus preserving service continuity while enabling thermal management

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for operating a user equipment (UE) includes detecting an occurrence of an overheating condition in the UE, and based thereon, determining a first set of operating capabilities of the UE from a second set of operating capabilities of the UE, where the first and second set of operating capabilities are associated with a connection between the UE and a network entity, and where the first set of operating capabilities is a reduction in operating capability of the UE when compared to the second set of operating capabilities, triggering a transfer of UE capability information associated with the first set of operating capabilities, and applying, by the UE, the first set of operating capabilities to the connection.
