Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems face challenges in efficiently managing uplink and downlink resource configurations for services like XR, which require simultaneous validation of Semi-Persistent Scheduling (SPS) and Configured Grants (CG) due to their complex and energy-consuming blind detection processes.

Innovation Solution

A single Downlink Control Information (DCI) is used to indicate both validation and release of multiple SPSs and CGs, optimizing the resource allocation by combining SPS and CG release combinations through modified or new DCI formats, reducing the need for separate DCI transmissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by stationary object

If separate DCIs are used to validate SPS and CG, then validation accuracy is maintained, but energy consumption increases due to multiple blind detections

Engineering Contradiction:

Improveenergy consumptionVSAvoidDCI transmission complexity

Core Design Contradiction:

Use of energy by stationary objectVSDevice complexity

Solution Approach 1:

The patent combines the validation of SPS and CG into a single DCI format, allowing both scheduling types to be validated simultaneously through one blind detection process, thereby reducing energy consumption while maintaining validation accuracy

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The DCI format is designed to perform multiple functions - validating both SPS and CG - making it a universal control mechanism that replaces what would traditionally require separate specialized DCIs

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If multiple separate DCIs are transmitted for SPS and CG validation, then validation flexibility is maintained, but the number of blind detections increases

Engineering Contradiction:

Improvevalidation efficiencyVSAvoidtime for blind detections

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

By merging SPS and CG validation into a single DCI, the patent reduces the number of blind detection operations from two separate detections to one combined detection, improving validation efficiency and reducing time loss

Inventive Principle:

Principle #5Merging (Combining)

3Use of energy by stationary object

If separate validation processes are used for SPS and CG, then validation precision is maintained, but power consumption increases

Engineering Contradiction:

Improvepower consumptionVSAvoidvalidation reliability

Core Design Contradiction:

Use of energy by stationary objectVSReliability

Solution Approach 1:

The patent maintains validation reliability by incorporating both SPS and CG validation fields within the same DCI structure, ensuring both scheduling types are validated with the same precision while sharing the same power consumption cost

Inventive Principle:

Principle #5Merging (Combining)
