Sidelink Resource Pool Activation for Power Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sidelink communication technologies in wireless systems face challenges in power savings due to the need for continuous scanning of resources by user equipment (UEs) regardless of traffic levels, leading to inefficient use of frequency resources and increased power consumption.
Innovation Solution
Implementing a bandwidth part (BWP) configuration with multiple resource pools, allowing for the activation and deactivation of secondary resource pools based on instantaneous traffic needs, enabling dynamic bandwidth adaptation and reducing unnecessary resource monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous scanning of frequency resources is performed regardless of traffic levels, then reliable sidelink communication is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic resource pool activation and deactivation based on traffic conditions. The UE activates secondary resource pools when traffic is detected and deactivates them when traffic is absent, making the resource monitoring behavior adaptive rather than static. This resolves the contradiction by maintaining reliability during high traffic while saving power during low traffic periods.
Solution Approach 2:
The patent changes the operational parameters of resource pools dynamically. By activating or deactivating secondary resource pools based on traffic conditions, the system adjusts its resource monitoring parameters to match actual communication needs, thereby reducing unnecessary power consumption while maintaining communication reliability when required.
2Productivity
If multiple resource pools are configured for sidelink communication, then frequency resource utilization is improved, but device complexity increases
Solution Approach 1:
The patent segments the frequency resources into multiple independent resource pools (primary and secondary). Each resource pool can be independently activated or deactivated, allowing the system to utilize multiple frequency resources when needed while managing complexity through modular, independent control of each segment.
Solution Approach 2:
The patent creates a universal resource pool structure where the primary resource pool and secondary resource pools serve the same sidelink communication function but can be activated based on traffic conditions. This multi-functionality approach allows flexible resource utilization without proportionally increasing complexity, as the same management mechanisms apply to all resource pools.
3Quantity of substance
If secondary resource pools are activated for high traffic periods, then available resources increase, but power consumption increases
Solution Approach 1:
The patent implements periodic activation and deactivation of secondary resource pools based on traffic detection. During high traffic periods, secondary resource pools are activated to provide additional resources. During low traffic periods, they are deactivated to save power. This periodic on-demand approach ensures resources are available when needed while minimizing power consumption during idle periods.

AI summary
Apparatus, methods, and computer-readable media for facilitating sidelink resource pool activation and deactivation for sidelink communication are disclosed herein. An example method for wireless communication at a first sidelink device includes identifying a configuration of a bandwidth part (BWP) for sidelink communication. In some examples, the BWP may comprise at least a first resource pool including a first subset of frequency resources and a second resource pool including a second subset of frequency resources. The example method also includes receiving an activation indication activating the second subset of frequency resources of the second resource pool. Additionally, the example method includes activating the second subset of frequency resources of the second resource pool based on the activation indication.
