Solution Overview

Problem

Current sidelink resource selection methods in communication technologies face reliability issues due to random selection of resources, often resulting in conflicts with other resources, leading to low reliability of sidelink transmission.

Innovation Solution

A sidelink resource selection processing method and apparatus that determines a non-preferred resource set and performs resource exclusion based on a preset rule, improving the reliability of sidelink transmission by selectively excluding resources that may cause conflicts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If resources are randomly selected from the target candidate resource set, then the resource selection process is simple and fast, but the transmission reliability deteriorates due to frequent conflicts with other resources

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidresource selection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by performing resource exclusion before random selection. The terminal excludes resources that may cause conflicts (such as resources with strong interfering signals or resources reserved by other terminals) from the candidate set in advance, thereby improving transmission reliability without adding complexity to the final selection process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent extracts harmful resources from the candidate resource set. By identifying and removing resources that are likely to cause conflicts (through RSRP threshold filtering and reserved resource exclusion), the patent creates a cleaner resource set for random selection, addressing the reliability issue without affecting the simplicity of the selection mechanism

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If resource exclusion is performed based only on RSRP and non-monitored slot, then the resource selection process is simple, but the transmission reliability deteriorates due to random selection conflicts

Engineering Contradiction:
ImproveSL transmission reliabilityVSAvoidresource selection ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the parameters used for resource exclusion by introducing multiple exclusion criteria beyond just RSRP and non-monitored slot. These include excluding resources with RSRP above a threshold, excluding resources reserved by other terminals, and excluding resources in certain time windows, thereby improving reliability while maintaining operational simplicity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent segments the resource exclusion process into multiple independent steps: first excluding resources based on RSRP threshold, then excluding reserved resources, and finally selecting from the remaining resources. This segmentation allows each exclusion criterion to be applied independently, maintaining ease of operation while improving reliability

Inventive Principle:
Principle #1Segmentation
