Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless technologies fail to efficiently manage the power consumption of the power consumption of the wireless resources of the wireless resources of the wireless resources of the wireless resources of the primary and secondary receivers of the primary and secondary receivers of the primary and secondary receivers of the terminal device, limiting the utilization rate of wireless resources due to semi-static resource configuration.
Innovation Solution
The terminal device determines a first resource based on a received first signal to receive a second signal that wakes up the primary receiver, allowing the network device to dynamically adjust resource allocation according to actual usage, thereby improving resource flexibility and utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If semi-static resource configuration is used for wake up signal, then terminal device power consumption is reduced, but wireless resource utilization rate deteriorates
Solution Approach 1:
The patent transforms the static resource configuration into a dynamic one by introducing a two-stage approach: semi-static configuration for basic resource allocation and dynamic indication via downlink control information (DCI) for real-time adjustments. This allows the resource allocation to adapt to actual traffic conditions and network state, resolving the contradiction between maintaining low power consumption (through continued use of secondary receiver) and improving resource utilization (through dynamic reconfiguration without full primary receiver activation).
Solution Approach 2:
The patent changes the resource allocation parameters from fixed semi-static values to dynamically adjustable parameters indicated through DCI. The network device can modify resource parameters (such as resource blocks, time slots, or frequency positions) based on actual network conditions, allowing the same wake-up signal mechanism to achieve both low power consumption and high resource utilization by varying these parameters adaptively.
2Device complexity
If semi-static resource configuration is used for wake up signal, then resource configuration complexity is reduced, but resource flexibility deteriorates
Solution Approach 1:
The patent segments the resource configuration into two independent parts: a semi-static baseline configuration that provides structural framework and reduces complexity, and a dynamic indication layer through DCI that provides flexibility. This segmentation allows the system to maintain simple overall structure while achieving fine-grained adaptive control, as the dynamic adjustments build upon rather than replace the entire configuration.
Solution Approach 2:
The patent performs preliminary resource configuration semi-statically before actual wake-up operations, establishing a pre-agreed framework between network and terminal. This preliminary action reduces the complexity of real-time decisions by having most parameters pre-determined, while still allowing flexibility through subsequent dynamic indications that refine the pre-configured resources based on immediate needs.
