Solution Overview

Problem

In wireless communication systems, there is a need for a flexible resource scheduling method to manage diverse types of service data and system control information efficiently, as different data transmissions or information transmissions often occupy the same or different time-frequency resources, leading to inefficiencies and conflicts.

Innovation Solution

A resource scheduling method involving the exchange of configuration information through messages to allocate non-overlapping resources for system control information and data, with additional indications to avoid conflicts and optimize resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If system control information and service data share the same time-frequency resources, then resource utilization improves, but resource conflicts and transmission reliability deteriorate

Engineering Contradiction:

Improveresource utilizationVSAvoidtransmission reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments time-frequency resources into distinct types: first resources for system control information/signals and second resources for service data. This segmentation prevents resource conflicts while maintaining efficient utilization by clearly defining separate allocation zones for different traffic types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic resource scheduling where the network device flexibly allocates first and second resources based on actual service requirements and channel conditions. This dynamic adjustment allows the system to optimize resource utilization while ensuring reliable transmission by adapting resource distribution to changing conditions.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If flexible resource scheduling is implemented, then adaptability improves, but resource scheduling overhead increases

Engineering Contradiction:

Improveresource scheduling flexibilityVSAvoidresource scheduling overhead

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs preliminary resource indication where the network device pre-configures resource allocation information for both system control and service data before actual transmission. This preliminary action reduces scheduling overhead by establishing resource frameworks in advance, allowing flexible adaptation without excessive real-time signaling.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a universal resource scheduling framework that handles multiple types of traffic (system control information, signals, and service data) through a unified allocation mechanism. This multi-functional approach reduces overhead by using consistent scheduling procedures across different resource types rather than separate specialized mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

This application provides a resource scheduling method, a communication apparatus, and a terminal device, and may be applied to the field of short-range communication. According to the method, a second node sends a first message to a first node, where the first message includes a first indication, the first indication indicates configuration information of a first resource, and the first resource is for communication of system control information and/or a system control signal. The second node communicates first data with the first node by using a second resource, where the second resource does not overlap the first resource.
