Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices, particularly C-V2X devices, face issues with high temperatures and power consumption due to continuous operation, leading to thermal issues and inefficient power expenditure.
Innovation Solution
Adaptive operational mode setting for circuits by adjusting parameters such as voltage levels and clock frequencies based on predictions or determinations of blind decodes and receive traffic to reduce unnecessary power consumption and temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous operation mode is used to ensure communication availability, then system reliability is improved, but temperature and power consumption increase
Solution Approach 1:
The patent implements dynamic operational mode adjustment by transitioning the circuit between first operational mode (high performance, higher power) and second operational mode (low power) based on detected traffic conditions. This dynamic switching resolves the contradiction by adapting the operating state to actual needs rather than maintaining continuous high-power operation.
Solution Approach 2:
The patent changes operational parameters (power state, operational mode) based on traffic condition detection. By monitoring traffic patterns and adjusting parameters accordingly, the system maintains reliability when needed while reducing temperature and power consumption during low-activity periods.
2Reliability
If continuous operation mode is used to ensure communication availability, then system reliability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts power consumption by switching between operational modes based on real-time traffic condition detection, ensuring reliability is maintained only when actually needed rather than consuming power continuously.
Solution Approach 2:
The patent employs periodic monitoring of traffic conditions and periodic switching between operational modes. This periodic action allows the system to maintain reliability during active periods while reducing power consumption during inactive periods, resolving the contradiction between continuous availability and power usage.
3Productivity
If high operational mode is maintained to handle peak traffic, then communication performance is improved, but unnecessary power expenditure increases during low traffic
Solution Approach 1:
The patent changes operational parameters based on detected traffic conditions, transitioning between high-performance mode and low-power mode. This parameter adaptation ensures high communication performance during peak traffic while avoiding unnecessary power expenditure during low-traffic periods.
Solution Approach 2:
The system dynamically adapts its operational characteristics to match actual traffic demands, being highly productive when needed and energy-efficient when not needed, thus resolving the contradiction between performance and energy loss.

AI summary
Methods, systems, and devices for wireless communications are described. Generally, the user equipment (UE) may adjust an operational mode of a circuit of the UE by selecting one or more parameters (e.g., power level or clock frequency or both). Adjusting parameter values may result in avoiding increased temperature. The UE may set an operational mode of a circuit based on a determination or a prediction of a number of blind decodes to be performed, a number of pending receive packets, or a number of transmitting UEs from which the UE will receive traffic. The UE may efficiently reduce unnecessary power expenditures and decrease temperature.
