Modem Clock Frequency Adaptation for Dynamic Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems face challenges in optimizing modem clock frequencies due to semi-static and dynamic configuration parameters, leading to inefficient power consumption and performance, as updating frequencies for dynamic changes is impractical and storing all combinations is prohibitive.
Innovation Solution
Implement techniques for predicting dynamic configurations and operating the modem clock at a frequency that supports the predicted configuration, rather than the worst-case scenario, allowing for power savings by using a minimum frequency required for the actual dynamic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the modem clock frequency is updated for every dynamic configuration change, then the system performance is improved, but the complexity and power consumption increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-determining the relationship between semi-static configuration parameters and modem clock frequencies. The network entity configures the UE with a semi-static configuration that includes parameters indicating which clock frequency to use for specific dynamic configuration scenarios, eliminating the need for real-time frequency updates during dynamic changes.
Solution Approach 2:
The patent implements dynamics by allowing the modem clock frequency to adapt based on the combination of semi-static and dynamic configuration parameters. The system dynamically selects from a set of pre-configured frequency options rather than continuously updating, balancing adaptability with system stability.
2Adaptability or versatility
If all combinations of semi-static and dynamic configuration parameters are stored, then complete coverage is achieved, but the memory requirements become prohibitive
Solution Approach 1:
The patent applies segmentation by dividing the configuration space into semi-static parameters (configured by the network) and dynamic parameters (changing during operation). The semi-static configuration contains parameters that map specific dynamic scenarios to appropriate clock frequencies, avoiding the need to store all possible combinations.
Solution Approach 2:
The patent uses parameter changes by introducing semi-static configuration parameters that define the relationship between dynamic configurations and clock frequencies. Instead of storing complete configuration combinations, the system stores parameter mappings that enable derivation of the appropriate frequency based on current dynamic conditions.
3Reliability
If the modem operates at a higher clock frequency to support worst-case scenarios, then reliability is improved, but power consumption increases unnecessarily
Solution Approach 1:
The patent applies parameter changes by configuring the modem to operate at different clock frequencies based on the actual dynamic configuration parameters. The semi-static configuration provides guidance on which frequency is appropriate for given dynamic scenarios, allowing the system to use lower frequencies when high performance is not required, thus reducing power consumption while maintaining reliability.
