Dual-Carrier User Equipment Power Sharing Verification With Output Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing standards for dual carrier dynamic power sharing in user equipment do not adequately verify if a device supports dynamic power sharing, leading to conservative power usage that limits available power for secondary cell groups, and current verification methods do not ensure that unused power by the master cell group is made available to the secondary cell group.
Innovation Solution
A method and apparatus for verifying dynamic power sharing by assigning resource block allocations and modulations to both carriers, providing power up and down commands to measure output powers, and determining if the secondary carrier's power increases as the primary carrier's power decreases, ensuring power is dynamically shared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conservative power management is used in dual carrier operations, then reliability of communication connections is improved, but power availability for secondary cell group is reduced
Solution Approach 1:
The patent implements dynamic power sharing between master and secondary cell groups by continuously monitoring power requirements and adjusting power allocation in real-time. The system transitions from static conservative power management to dynamic adjustment, allowing the secondary cell group to receive additional power when the master cell group's power requirements decrease, thereby resolving the contradiction between reliability and power availability.
Solution Approach 2:
The verification method employs feedback mechanisms by measuring output powers of both carriers and determining whether power sharing is properly implemented. The system monitors the relationship between master cell group power reduction and secondary cell group power increase, using this feedback to ensure reliable operation while optimizing power distribution to the secondary cell group.
2Adaptability or versatility
If existing verification methods are used, then device compatibility is improved, but verification accuracy of dynamic power sharing is reduced
Solution Approach 1:
The patent applies preliminary action by assigning specific resource block allocations and modulation schemes to both carriers before verification. This preparation ensures that the verification process can accurately measure power dynamics without disrupting existing device compatibility, as the test configuration is established in advance according to standard protocols.
Solution Approach 2:
The patent replaces existing verification methods with an improved verification approach that uses power measurement and comparison logic. Instead of relying on conventional verification mechanisms, the system substitutes a new method that measures output powers, compares power changes between carriers, and determines verification results based on whether the secondary carrier's power increases when the primary carrier's power decreases, thereby achieving higher verification accuracy while maintaining compatibility.

AI summary
Verification of dynamic power sharing in a user equipment (UE) between a first and second carrier transmission is provided. Resource block allocations and modulations for both first (502) and second (504) carriers transmitted from the UE are assigned. The UE provides (506) a series of power up commands for both the first carrier and the second carrier until the measured output powers for the first carrier and the second carrier no longer increase. Power down commands are then provided (508) for the first carrier while providing power up commands to the second carrier. The output power for the first carrier and the second carrier is then measured (510) and a determination is made as to whether the output power for the second carrier increases as the output power for the first carrier decreases.
