Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing power utilization in user equipment (UE) during high efficiency transmission operating modes, leading to suboptimal power amplifier performance and potential interference issues.
Innovation Solution
The implementation of a method in user equipment (UE) to selectively operate in either a high efficiency transmission operating mode or a lower efficiency mode based on communication parameters, such as scheduled uplink bandwidth, modulation and coding schemes, and frequency resource allocation, to optimize power amplifier efficiency and minimize undesired emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the UE operates in the first transmission efficiency operating mode (higher efficiency mode), then power amplifier efficiency is improved, but undesired emission level increases
Solution Approach 1:
The patent implements dynamic mode selection where the UE can switch between first and second transmission efficiency operating modes based on real-time communication parameters. The UE determines whether to operate in the higher efficiency mode (first mode) or lower efficiency mode (second mode) by evaluating parameters such as scheduled uplink bandwidth, modulation and coding schemes, and frequency resource allocation, thereby dynamically balancing power amplifier efficiency against undesired emission levels
Solution Approach 2:
The patent changes operational parameters to resolve the contradiction. By modifying transmission parameters (bandwidth, modulation scheme, frequency allocation) and corresponding power amplifier settings, the system can adjust the operating mode to achieve acceptable power efficiency while maintaining emission levels within regulatory limits
2Use of energy by moving object
If the UE selects the first transmission efficiency operating mode, then power efficiency is improved, but communication parameter constraints increase
Solution Approach 1:
The system dynamically adapts communication parameters based on the selected operating mode. When operating in the first transmission efficiency mode, the UE adjusts parameters such as scheduled uplink bandwidth, modulation and coding schemes, and frequency resource allocation to satisfy the mode's specific requirements, thereby maintaining power efficiency while adapting to different communication scenarios
3Object-generated harmful factors
If the UE operates in the second transmission efficiency operating mode (lower efficiency mode), then undesired emission level is reduced, but power amplifier efficiency decreases
Solution Approach 1:
The patent extracts and separates the power amplifier operation into distinct operating modes. By isolating the higher efficiency mode (first mode) with its associated higher emission characteristics from the lower efficiency mode (second mode) with lower emissions, the system can selectively apply the appropriate mode based on communication conditions, thereby managing the trade-off between power efficiency and emission levels

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be capable of operating according to a first transmission efficiency operating mode and a second transmission efficiency operating mode that is less power efficient than the first transmission efficiency operating mode. The first transmission efficiency operating mode may be associated with a first undesired emission level that is greater than a second undesired emission level associated with the second transmission efficiency operating mode. The UE may select to operate in one of the two transmission efficiency operating modes based on one or more communication parameters (e.g., indicated by control signaling received from a base station). For example, the UE may select to operate in the first transmission efficiency operating mode based on determining that one or more of the communication parameters satisfies at least one parameter criterion for operating in the first transmission efficiency operating mode.
