Solution Overview

Problem

Existing wireless communication technologies are limited to indicating transmission resources in only one subframe, restricting flexibility and efficiency in resource allocation.

Innovation Solution

A method and apparatus for determining and indicating multiple time domain resources using resource indication information, where the value of the indication is determined by the positions and intervals of the resources, allowing for more flexible and efficient resource allocation across multiple subframes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional resource indication methods are used, then resource allocation can be performed, but only in a single subframe which limits flexibility and efficiency

Engineering Contradiction:

Improveresource allocation flexibilityVSAvoidresource indication complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the resource indication into two parts: a first resource indication value indicating the first time domain resource, and a second resource indication value indicating the second time domain resource. This segmentation allows independent indication of multiple time domain resources, enabling flexible resource allocation across multiple subframes while maintaining manageable complexity through structured indication mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extends resource indication from a single time domain dimension to multiple time domain dimensions by introducing multiple resource indication values. Each resource indication value operates in the time domain but refers to different time resources, effectively adding a temporal multiplicity dimension that enables cross-subframe resource allocation without proportionally increasing overall system complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If multiple time domain resources are indicated using separate indication methods, then resource allocation flexibility improves, but signaling overhead and complexity increase

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidsignaling overhead

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent merges multiple resource indication functions into a unified indication framework where a single resource indication message contains both the first resource indication value and the second resource indication value. This combining approach enables efficient indication of multiple time domain resources in one signaling event, improving resource allocation efficiency while minimizing signaling overhead by avoiding separate indication messages.

Inventive Principle:

Principle #5Merging (Combining)
