Solution Overview

Problem

Existing technologies fail to effectively determine the transmission location for sub-slot-based PUCCH resources in wireless communication systems, leading to inefficiencies.

Innovation Solution

A method and system for determining the sub-slot in which first information such as SR or CSI is located, based on starting symbol information and the number of symbols of the corresponding PUCCH resource, allowing for precise configuration of PUCCH resources within sub-slots.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If slot-based PUCCH resource configuration is used, then the transmission location can be determined, but the flexibility and precision for sub-slot based transmission is lost

Engineering Contradiction:

Improvetransmission location precisionVSAvoidsub-slot based configuration flexibility

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent divides the slot into multiple sub-slots and configures PUCCH resources at the sub-slot level rather than at the slot level. This segmentation enables more precise control over transmission locations within a slot, allowing the terminal to determine exact transmission positions for sub-slot based PUCCH resources while maintaining flexibility in resource configuration.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If sub-slot based PUCCH resource is configured, then transmission flexibility is improved, but the transmission location determination becomes unclear

Engineering Contradiction:

Improveresource configuration flexibilityVSAvoidtransmission location determination

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces preliminary determination of the sub-slot containing the first information (SR or CSI) before finalizing the transmission location. By first identifying which sub-slot contains the information and then determining the PUCCH resource location within that sub-slot based on starting symbol and number of symbols, the transmission location is clearly determined while maintaining configuration flexibility.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If periodicity and offset based determination is used, then the transmission schedule is simplified, but the precision for sub-slot level transmission is reduced

Engineering Contradiction:

Improvetransmission scheduling complexityVSAvoidsub-slot transmission precision

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent combines periodicity-based scheduling with dynamic sub-slot level adjustments. The terminal determines the sub-slot based on periodicity and offset, then further精确定位 the transmission location within that sub-slot using starting symbol and number of symbols parameters. This dynamic approach maintains scheduling simplicity while achieving sub-slot level precision.
