Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently managing resource pools and sidelink primary cells, leading to suboptimal power consumption and resource utilization.
Innovation Solution
A method and apparatus for wireless communication that involve transmitting a sidelink bandwidth configuration message to switch the primary resource designation from one sidelink resource to another, allowing for dynamic management of resource pools and primary cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource pools and sidelink primary cells are continuously monitored to ensure communication reliability, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic switching between first and second resource pools based on monitoring conditions. When the number of monitored sidelink transmissions exceeds a threshold, the device switches to the second resource pool, enabling adaptive resource allocation that balances reliability and power consumption.
Solution Approach 2:
The device autonomously monitors sidelink transmissions and automatically switches resource pools based on predefined criteria without continuous network control. This self-service mechanism allows the device to manage its own power consumption while maintaining communication reliability.
2Productivity
If multiple resource pools are continuously monitored to improve resource utilization, then resource utilization is improved, but device complexity increases
Solution Approach 1:
The patent divides resource management into two distinct resource pools with different monitoring requirements. The first resource pool uses standard monitoring while the second resource pool uses reduced monitoring, segmenting the overall resource management task to reduce device complexity while maintaining utilization.
Solution Approach 2:
The patent changes monitoring parameters dynamically by switching between different resource pools. When switching to the second resource pool, the monitoring threshold and intensity are adjusted, allowing the device to manage complexity through parameter modification rather than structural complexity.

AI summary
A first device may be configured to implement a procedure for resource pool and sidelink primary cell switching. In some aspects, the first device may transmit, to a second device monitoring a first sidelink resource, a sidelink bandwidth configuration message causing the second device to monitor a second sidelink resource, and switch a primary resource designation from the first sidelink resource to the second sidelink resource, the primary resource designation corresponding to communication of management information and/or acknowledgement information. Further, the first device may communicate, based on the switching, the management information and/or the acknowledgement information with the second device via the second sidelink resource.
