UE Power Class Signaling for Region-Specific Transmission Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment operating in multiple power classes faces inefficiencies due to networks configuring transmission power based on a higher power class, even when the equipment is capable of a lower power class, leading to suboptimal operation and transmission inefficiencies.
Innovation Solution
User equipment indicates support for multiple power classes to the network, allowing the network to accurately configure transmission power characteristics based on the actual power class in use, optimizing power usage according to regional regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user equipment indicates only one power class (higher power class) to the network, then the network can configure transmission power characteristics, but the network may configure based on higher power class even when lower power class is required by regional regulations, leading to transmission inefficiencies
Solution Approach 1:
The patent segments the power class indication into multiple separate indications - one for higher power class capability and another for lower power class capability. This allows the network to receive distinct information about what power classes the UE can actually operate in, enabling more precise configuration that matches regional regulatory requirements while avoiding the inefficiency of always assuming highest power class operation
Solution Approach 2:
The patent introduces dynamic power class indication where the UE can indicate different power classes based on current operating conditions and regional regulations. The network can then dynamically configure transmission power characteristics appropriate to the specific scenario, rather than using a static configuration based on maximum capability alone
2Power
If user equipment operates in higher power class with higher maximum transmission power, then transmission range and coverage are improved, but energy consumption increases and regulatory compliance may be violated in regions with lower emission limits
Solution Approach 1:
The patent enables parameter changes by allowing the network to configure different transmission power characteristics based on the indicated power class. When lower power class is indicated, the network configures appropriate power parameters that reduce energy consumption while still meeting communication requirements. This dynamic parameter adjustment ensures compliance with regional emission limits without unnecessarily consuming energy

AI summary
Embodiments herein provide various apparatuses and techniques that indicate multiple power classes that user equipment may support to a network. The user equipment may support at least a lower power class (e.g., having a lower maximum transmission power) and a higher power class (e.g., having a higher maximum transmission power) to the network. The user equipment may send indications to the network that it supports both the lower power class and the higher power class. If the network/user equipment are in a geographical region associated with regulations limiting transmission power to the lower maximum transmission power, then the network may configure a transmission power characteristic based on the lower power class. If the network/user equipment are in a geographical region associated with regulations limiting transmission power to the higher maximum transmission power, then the network may configure the transmission power characteristic based on the higher power class.
