COT Remaining Duration Indication in High-Frequency Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the available duration for data communication in high-frequency communication bands are inadequate, as they cannot accurately indicate channel occupy time remaining duration and fail to specify which beam the COT remaining duration is applied to.
Innovation Solution
A method and apparatus that determine an available duration for data communication by receiving channel occupy time (COT) information, including COT remaining duration and application beam indication, and using this information to accurately determine the available duration for data reception or transmission in high-frequency communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the prior art COT remaining indication method is used, then the method is simple and compatible with existing systems, but it cannot accurately indicate COT remaining duration in high-frequency communication bands
Solution Approach 1:
The patent changes the parameters of COT remaining duration indication by introducing multiple indication values with different granularities (first indication value with first granularity, second indication value with second granularity). This allows the system to accurately represent COT remaining duration in high-frequency bands by selecting appropriate granularity levels, thereby improving measurement precision without excessive complexity.
Solution Approach 2:
The patent segments the COT remaining duration indication into multiple parts: a first indication value indicating a first COT remaining duration, and a second indication value indicating a second COT remaining duration. This segmentation allows each part to operate at different granularity levels, improving overall indication accuracy while maintaining manageable complexity through modular structure.
2Loss of information
If the COT remaining indication method is expanded to include beam information, then the specification of applicable beam is improved, but the information structure becomes more complex
Solution Approach 1:
The patent merges COT remaining duration indication with beam applicability indication into a unified information structure. The first and second indication values are combined with beam information to simultaneously convey both the remaining duration and the beam to which it applies, reducing information loss while managing complexity through integrated design.
Solution Approach 2:
The patent introduces an intermediary structure that links COT remaining duration values with beam identifiers. This intermediary mechanism allows the system to specify which beam the COT remaining duration applies to without creating excessive complexity, by establishing a clear mapping relationship between duration values and beam information.
