Resource Exclusion for Multi-Module Sidelink Communication

Solution Overview

Problem

In New Radio (NR) systems, there is a need for an effective resource exclusion method in Sidelink (SL) communications to avoid conflicts between transmission resources of different communication modules, such as NR and LTE modules, especially when they share the same carrier, as existing methods fail to efficiently manage resource conflicts and ensure reliable communication.

Innovation Solution

A resource exclusion method is implemented in a terminal device with two communication modules, where one module performs resource exclusion based on target resources indicated by the other module, excluding resources that overlap or have conflicting priority levels, thereby avoiding conflicts and ensuring reliable communication by determining a resource set that does not interfere with the other module's selected or scheduled resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple communication modules (NR and LTE) share the same carrier for transmission, then resource utilization efficiency is improved, but resource conflicts between modules occur leading to communication reliability deterioration

Engineering Contradiction:

Improveresource utilization efficiencyVSAvoidcommunication reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments the resource pool into multiple subsets, with each subset assigned to a specific communication module (NR or LTE). This segmentation prevents resource conflicts by ensuring that each module operates in its designated resource subset, thereby maintaining communication reliability while allowing both modules to utilize the shared carrier effectively.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary resource exclusion by identifying and removing resources that would cause conflicts between NR and LTE modules before actual transmission occurs. By pre-excluding conflicting resources from the available resource pool, the system ensures that only non-conflicting resources are selected for transmission, thus maintaining reliability while enabling efficient resource sharing.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If resource exclusion is performed to avoid conflicts between communication modules, then communication reliability is improved, but resource selection flexibility is reduced

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidresource selection flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent performs preliminary resource exclusion by identifying and removing resources that would cause conflicts between NR and LTE modules before actual transmission occurs. By pre-excluding conflicting resources from the available resource pool, the system ensures that only non-conflicting resources are selected for transmission, thus maintaining reliability while enabling efficient resource sharing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent dynamically adjusts the resource exclusion process based on the specific transmission requirements and channel conditions of each communication module. The resource selection is adapted in real-time according to the actual usage patterns and interference conditions, allowing the system to maintain flexibility while ensuring reliability through targeted resource exclusion.
