Solution Overview

Problem

Existing technologies lack a method for determining a Hybrid Automatic Repeat reQuest (HARQ) process identity (ID) for Sidelink Configured Grant in New Radio (NR) systems.

Innovation Solution

A method is provided to determine a HARQ process ID for Sidelink Configured Grant by receiving configuration information, determining time domain information, and using this information to allocate HARQ process IDs based on the Sidelink Configured Grant transmission resource, including determining a period parameter and slot index.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a method for determining HARQ process ID is provided for downlink SPS transmission resource or UL CG resource, then the HARQ process ID can be determined for these resources, but no method is available for determining HARQ process ID for Sidelink Configured Grant

Engineering Contradiction:
ImproveHARQ process ID determination methodVSAvoidHARQ process ID for Sidelink Configured Grant
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent extends the HARQ process ID determination mechanism from downlink SPS and UL CG resources to Sidelink Configured Grant resources. By using a universal formula that works across different resource types (downlink, uplink, and sidelink), the system achieves multi-functionality without requiring separate determination methods for each resource type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent modifies the HARQ process ID determination by introducing specific parameters for Sidelink Configured Grant resources, including time domain information, period parameters, and resource pool indices. These parameter changes enable the determination of HARQ process IDs specifically for sidelink resources while maintaining consistency with existing downlink and uplink mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If configuration information is received and time domain information is determined, then HARQ process ID can be allocated, but the system complexity increases due to additional determination steps

Engineering Contradiction:
ImproveHARQ process ID allocationVSAvoiddetermination process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent performs preliminary determination of time domain information and period parameters during the configuration phase. By pre-calculating these values and storing them in the configuration information, the actual HARQ process ID allocation becomes a simple lookup and calculation operation, reducing the complexity of the operational phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent divides the HARQ process ID determination into distinct segments: receiving configuration information, determining time domain information, determining period parameters, and finally calculating the HARQ process ID. This segmentation allows each step to be handled independently and systematically, making the overall complex process more manageable and easier to implement.

Inventive Principle:
Principle #1Segmentation
