Solution Overview

Problem

In-vehicle communication systems face challenges with low transmission reliability of scheduling signaling due to the large amount of content and information required, leading to increased blind detection and complexity.

Innovation Solution

A two-level scheduling method is implemented, where first signaling indicates corresponding communications apparatuses with minimal information, reducing the need for additional indication in second signaling, and associating resources to simplify blind detection and improve reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the scheduling signaling includes a large amount of content and information, then the scheduling capability is comprehensive, but the transmission reliability is low

Engineering Contradiction:
Improvescheduling capabilityVSAvoidtransmission reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The scheduling signaling is divided into two separate parts: first signaling that indicates which communications apparatuses are scheduled, and second signaling that contains the detailed scheduling information. This segmentation reduces the size of each individual signaling message, thereby improving transmission reliability while maintaining comprehensive scheduling capability through the combination of both signals.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If the scheduling signaling includes a large amount of content, then more information can be transmitted, but the blind detection amount increases

Engineering Contradiction:
Improveinformation amountVSAvoidblind detection amount
Core Design Contradiction:
Quantity of substanceVSDifficulty of detecting and measuring

Solution Approach 1:

The detection process is segmented into two stages: first detecting the first signaling to identify which apparatuses are scheduled, then only detecting the second signaling for the scheduled apparatuses. This reduces the overall blind detection amount compared to detecting a single large signaling message containing all information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first signaling performs a preliminary action of identifying which communications apparatuses are scheduled before the second signaling is processed. This preliminary identification allows subsequent apparatuses to skip unnecessary detection, reducing the total blind detection amount while still transmitting all necessary scheduling information.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If conventional scheduling signaling is used, then the scheduling function is complete, but the implementation complexity is high

Engineering Contradiction:
Improvescheduling functionVSAvoidimplementation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The scheduling function is segmented into two independent parts: first signaling for identification and second signaling for detailed scheduling information. This segmentation simplifies the implementation complexity by reducing the processing burden on each individual component, while the combination of both signals maintains complete scheduling functionality.

Inventive Principle:
Principle #1Segmentation

AI summary

This application relates to a scheduling method, an apparatus, and a system. A first communications apparatus sends first signaling on a first resource, where the first signaling is used to indicate N communications apparatuses. The first communications apparatus sends second signaling on a second resource, where the second signaling is used to schedule the N communications apparatuses to send or receive first data, and the first resource has an association relationship with the second resource. In addition, the first resource has the association relationship with the second resource. In this case, a receive end of the first signaling and the second signaling may determine the second resource after determining the first resource, so that the second signaling is only detected on the second resource, and blind detection does not need to be performed on too many resources.
