Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multicarrier communication systems face challenges in efficiently managing power adjustment and radio resource allocation across different carriers and cells, leading to suboptimal performance in terms of data transmission and quality of service.
Innovation Solution
The implementation of advanced radio access network architecture and protocol stacks, including dynamic modulation and coding schemes, and the use of next-generation Node B (gNB) and evolved Node B (ng-eNB) nodes, which enable dynamic bandwidth part configuration and multi-connectivity scenarios to optimize power adjustment and resource allocation.

Engineering Contradiction Analysis
1Productivity
If dynamic power adjustment is implemented across multiple carriers, then data transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments power management by introducing separate power priority indicators for different carriers (first carrier and second carrier). Each carrier can be independently configured with its own power priority level, allowing the device to manage power adjustments on a per-carrier basis rather than globally, thus improving transmission efficiency while maintaining manageable complexity through modular control
Solution Approach 2:
The patent implements dynamic power adjustment mechanisms where the wireless device can adaptively modify transmit power based on real-time channel conditions and carrier priority configurations. The power adjustment is dynamically controlled through RRC signaling that configures carrier-specific power priority indicators, enabling the system to respond to changing network conditions while maintaining structured power management
2Productivity
If carrier-specific power priority configuration is implemented, then resource allocation optimization is improved, but signaling overhead increases
Solution Approach 1:
The patent applies local quality by configuring power priority indicators specifically for carriers that require differentiated power management. Rather than uniformly configuring all carriers, the system selectively applies carrier-specific power priority configurations only where needed, optimizing resource allocation for critical carriers while minimizing unnecessary signaling overhead for carriers with default power management requirements

AI summary
A wireless device receives a grant indicating radio resources for transmission of a transport block via a first cell. The radio resources overlap in time with a configured transmission of a preamble via a second cell. a transmission power of one of the preamble or the transport block is adjusted based on a power priority of the preamble. The power priority of the preamble is: higher than a power priority of the transport block based on the second cell being a primary cell; and lower than the power priority of the transport block based on the second cell being a secondary cell. The transport block is transmitted via the radio resources.
