DRX BWP Switching Timing for Data-Loss-Free NR Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the new radio (NR) system, the inconsistent definition of BWP switching start times between terminal-side and network-side devices leads to potential data loss due to the terminal-side device being unable to receive data during the switching process, especially when both wake-up signal and dormancy indication information are sent using DCI.
Innovation Solution
A method to determine a synchronized start time for BWP switching by configuring a first time period during which the terminal-side device performs BWP switching, based on monitoring occasions of DCI format 2_6, ensuring the device is aligned with the network-side device's timing to avoid data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional detection methods using multiple electrodes and complex signal processing are used, then detection coverage can be achieved, but device complexity and processing time increase significantly
Solution Approach 1:
The patent extracts and removes the counter electrode from the traditional three-electrode configuration, reducing the system to just a reference electrode and working electrode. This simplification eliminates the complexity associated with multiple electrodes while maintaining detection capability through the use of a pseudocapacitive reference electrode that provides stable potential without requiring a counter electrode.
Solution Approach 2:
The reference electrode is designed to serve multiple functions simultaneously: it provides a stable reference potential for voltage control and acts as the sole electrode for both oxidation and reduction reactions. This multi-functionality eliminates the need for separate counter and reference electrodes, thereby reducing device complexity while maintaining comprehensive detection coverage.
2Reliability
If conventional detection methods with multiple electrodes are used, then comprehensive electrochemical detection can be performed, but the number of components and system complexity increase
Solution Approach 1:
The reference electrode performs multiple roles: it provides a stable reference potential for electrochemical measurements and serves as the active electrode for both anodic and cathodic reactions. This eliminates the need for separate counter and reference electrodes, reducing the quantity of electrodes from three to two while maintaining detection accuracy through the pseudocapacitive properties of the reference electrode.
Solution Approach 2:
The patent merges the functions of the counter electrode and reference electrode into a single reference electrode structure. By combining these functions, the system reduces the number of discrete components while maintaining the electrochemical detection capabilities through the unique pseudocapacitive behavior of the reference electrode material.
3Reliability
If traditional three-electrode systems are used, then electrochemical control can be maintained, but device simplicity and ease of manufacture are reduced
Solution Approach 1:
The counter electrode is extracted and removed from the system, simplifying the manufacturing process by reducing the number of components that need to be assembled and positioned. The reference electrode alone handles both reference potential provision and current-carrying functions, eliminating the need for precise positioning and electrical connections of a separate counter electrode.
Solution Approach 2:
The reference electrode is designed to perform multiple functions including providing reference potential and carrying reaction current, which simplifies the manufacturing process by reducing the number of specialized components needed. This multi-functional design allows for simpler assembly and manufacturing while maintaining reliable electrochemical control through the pseudocapacitive properties of the reference electrode.
