Engineering Contradiction Analysis
1Use of energy by moving object
If semi-static configuration is used for wake up signal resources, then terminal device power consumption is reduced through secondary receiver, but wireless resource utilization rate deteriorates due to inflexibility
Solution Approach 1:
The patent implements dynamic resource configuration for wake-up signals by allowing the network device to flexibly allocate time-frequency resources based on actual traffic conditions and system load. The resource allocation is no longer fixed but adapts to changing network conditions, resolving the contradiction between power saving (which requires simple semi-static configuration) and resource utilization (which benefits from flexible dynamic allocation).
Solution Approach 2:
The patent changes the resource allocation parameters from static to dynamic by introducing mechanisms where the network device can adjust wake-up signal resources according to actual usage patterns. This includes modifying time slot assignments, frequency resource blocks, and signal transmission parameters dynamically, thereby improving overall wireless resource utilization while maintaining the power-efficient secondary receiver operation.
2Device complexity
If semi-static resource configuration is used, then configuration complexity is reduced, but resource allocation flexibility deteriorates
Solution Approach 1:
The system transitions from static configuration to dynamic resource allocation where the network device can adaptively assign wake-up signal resources based on real-time network conditions, traffic patterns, and terminal device states. This dynamic approach enhances resource allocation flexibility without significantly increasing terminal device complexity, as the terminal simply follows network-provided resource indications.
Solution Approach 2:
The network device performs the complex resource allocation decisions autonomously based on system-wide information, eliminating the need for complex configuration management at the terminal device. The terminal device benefits from simplified operation while the network device handles the adaptability requirements, effectively distributing the complexity burden.
