Solution Overview

Problem

Terminal devices in wireless communication systems experience interference from neighboring devices, leading to decreased communication quality, particularly in dynamic uplink and downlink configurations, which existing methods fail to adequately address.

Innovation Solution

A wireless communication method where terminal devices measure and report cross-link interference to the network device using configuration information, enabling dynamic adjustment of transmission resources to mitigate interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If terminal devices perform downlink communication in neighboring cells with uplink communication, then communication resources are utilized, but cross-link interference occurs and communication quality decreases

Engineering Contradiction:

Improvecommunication resource utilizationVSAvoidcross-link interference

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where the first terminal device measures cross-link interference and reports measurement results to the network device. The network device uses this feedback information to adjust scheduling decisions and resource allocation, thereby resolving the contradiction between utilizing communication resources and reducing harmful interference effects.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by having the terminal device measure and report interference information before the actual communication occurs. This allows the network device to prepare scheduling decisions in advance that avoid or mitigate cross-link interference, while still enabling efficient resource utilization.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If terminal devices measure and report interference measurement results, then communication quality can be improved, but measurement and reporting overhead increases

Engineering Contradiction:

Improvecommunication qualityVSAvoidmeasurement and reporting overhead

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by configuring terminal devices to measure and report only the specific cross-link interference information relevant to their local communication scenario. The measurement and reporting are targeted and selective rather than comprehensive, reducing unnecessary overhead while maintaining communication quality improvement.

Inventive Principle:

Principle #3Local quality
