Sidelink Coordination Information for Autonomous Resource Selection

Solution Overview

Problem

In V2X communication systems, the autonomous resource selection mode between terminal devices lacks effective coordination, leading to resource wastage and unnecessary interference due to continuous monitoring and repeated procedures.

Innovation Solution

A communication method and apparatus that utilize coordination information to assist terminal devices in determining resource sets, including recommended, scheduled, and excluded resource sets, along with measurement results and indication information to optimize resource selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If terminal devices continuously and repeatedly perform monitoring or start related procedures in autonomous resource selection mode, then resource selection can be performed, but resource waste and unnecessary interference occur

Engineering Contradiction:

Improveresource selection efficiencyVSAvoidresource waste

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by having terminal devices perform resource selection and coordination procedures in advance before actual data transmission. The sending terminal device determines a first resource set for sending information and coordinates with the coordinating terminal device to determine a second resource set for receiving information before the actual communication occurs. This pre-planning of resource allocation eliminates the need for continuous monitoring and repeated procedures during actual transmission, thereby improving resource selection efficiency while reducing resource waste.

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary action by having terminal devices perform resource selection and coordination procedures in advance before actual data transmission. The sending terminal device determines a first resource set for sending information and coordinates with the coordinating terminal device to determine a second resource set for receiving information before the actual communication occurs. This pre-planning of resource allocation eliminates the need for continuous monitoring and repeated procedures during actual transmission, thereby improving resource selection efficiency while reducing resource waste.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces coordination information as an intermediary mechanism between the sending terminal device and the coordinating terminal device. This coordination information carries resource selection results and enables the coordinating terminal device to determine its receiving resources based on the sending terminal's selection. By using this intermediary coordination mechanism, the system reduces direct continuous monitoring between devices and minimizes unnecessary interference while maintaining efficient resource selection.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A communication method includes receiving coordination information. The coordination information is used by a first sidelink device to determine a first resource set. The first resource set is used by the first sidelink device to send information. The communication method also includes determining that the coordination information includes one or more of information about a second resource set recommended to the first sidelink device, information about a third resource set scheduled to the first sidelink device, information about a fourth resource set expected to be excluded by the first sidelink device, a coordination parameter or a measurement result, where the coordination parameter or the measurement result is used by the first sidelink device to determine the first resource set, or indication information, where the indication information instructs the first sidelink device to determine the first resource set.
