Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In communication systems with multiple groups sharing the same carrier, mutual interference occurs between communication groups.

Innovation Solution

Determine and indicate different transmission resource sets for each communication group to facilitate resource coordination among groups, using pre-configuration, semi-static, or dynamic modes.

1Productivity

If multiple communication groups use the same carrier for communication, then communication efficiency is improved, but mutual interference occurs between communication groups

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidmutual interference

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the communication resource space into separate transmission resource sets for different communication groups. Each group is assigned a dedicated resource set (time, frequency, or spatial resources) to eliminate mutual interference while maintaining overall system productivity through coordinated resource management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces additional resource dimensions (time domain, frequency domain, spatial domain) to resolve the interference problem. By allocating resources across multiple dimensions rather than a single carrier, the system can maintain high communication efficiency while preventing interference between groups.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If different transmission resource sets are allocated to different communication groups, then mutual interference is avoided, but resource coordination complexity increases

Engineering Contradiction:

Improvemutual interferenceVSAvoidresource coordination

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent introduces a network device as an intermediary to manage and coordinate transmission resources across multiple communication groups. This centralised controller allocates and adjusts resource sets, simplifying the coordination complexity while ensuring interference-free communication through systematic resource management.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic resource allocation where transmission resource sets can be adjusted based on communication conditions. The network device monitors and reconfigures resources in real-time, allowing the system to adapt to changing requirements while maintaining low interference levels.

Inventive Principle:

Principle #15Dynamics
