Minimum Scheduling Offset Switching for Terminal Power and Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication technology, when switching from cross-slot scheduling to same-slot scheduling, terminal equipment fails to detect the switching indication, leading to continued caching of PDSCH, resulting in increased power consumption and affected throughput performance due to misdetection of the minimum scheduling offset.
Innovation Solution
Implementing a method where the minimum scheduling offset switches back to a third minimum value in another switch back period after receiving the switching indication, ensuring timely scheduling and improved throughput by preventing misdetection and enabling caching of PDSCH.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal equipment switches the minimum scheduling offset from a first minimum value to a second minimum value upon receiving the switching indication, then the scheduling flexibility is improved, but the reliability deteriorates due to potential misdetection of the switching indication
Solution Approach 1:
The patent implements periodic switching between first and second minimum values at predetermined switch back periods. This periodic action ensures that even if a switching indication is missed during one period, the system automatically returns to the original state in the next period, thereby maintaining reliability while preserving scheduling flexibility.
Solution Approach 2:
The patent introduces a feedback mechanism where the terminal equipment monitors whether it correctly received and executed the switching indication by checking if the actual scheduling offset matches the expected value. This feedback allows the system to detect and correct misdetections, improving reliability without sacrificing scheduling adaptability.
2Reliability
If the terminal equipment continuously caches the PDSCH to ensure timely scheduling, then the scheduling reliability is improved, but the power consumption increases
Solution Approach 1:
The patent dynamically adjusts the minimum scheduling offset between first and second minimum values based on switching indications and time conditions. This dynamic adjustment allows the terminal equipment to optimize between caching PDSCH (when offset is zero) and not caching (when offset is non-zero), thereby balancing scheduling reliability with power consumption efficiency.
Solution Approach 2:
The patent changes the parameter of minimum scheduling offset between different values (first minimum value and second minimum value) based on switching indications and switch back periods. This parameter change enables the system to adapt the caching behavior dynamically, reducing power consumption while maintaining necessary scheduling reliability.
3Device complexity
If the terminal equipment uses a fixed minimum scheduling offset value, then the system complexity is reduced, but the scheduling efficiency deteriorates
Solution Approach 1:
The patent employs periodic switching between fixed minimum values at predetermined switch back periods. This approach maintains relative simplicity by using fixed values rather than continuous variable adjustment, while still improving scheduling efficiency through periodic optimization opportunities.

AI summary
This disclosure relates to a method, a device, and a storage medium for instructing a minimum scheduling offset. The method for instructing the minimum scheduling offset is applied in terminal equipment and includes: in a switch back period, receiving a minimum scheduling offset switching indication, the minimum scheduling offset switching indication to instruct switching the minimum scheduling offset from a first minimum value to a second minimum value; and causing the minimum scheduling offset to switch back to a third minimum value in another switch back period after the switch back period.
