Solution Overview

Problem

In TDD communication systems, cross-link interference (CLI) occurs when uplink and downlink transmissions in neighboring cells overlap, causing interference. This interference needs to be minimized to ensure effective communication.

Innovation Solution

A method for configuring CLI measurement is introduced, where a first network device receives a message from a second network device indicating CLI measurement information. This information includes the quantity or configuration of resources for CLI measurement, allowing the network devices to negotiate and optimize the CLI measurement configuration for a terminal device, ensuring it does not exceed the device's capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple network devices configure CLI measurement for a terminal device independently, then each network device can optimize its own CLI measurement, but the terminal device may exceed its CLI measurement capabilities and无法正常 perform measurements

Engineering Contradiction:
ImproveCLI measurement capabilityVSAvoidmeasurement configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary message exchange mechanism between network devices. The first network device receives CLI measurement configuration information from the second network device, and they coordinate through standardized messages to determine the final measurement configuration. This intermediary coordination prevents the terminal device from being overwhelmed by excessive measurement requirements while maintaining the ability of each network device to optimize its own CLI measurement needs.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary action by having network devices exchange CLI measurement configuration information before the terminal device actually performs measurements. The first network device receives configuration information from the second network device in advance, and based on this preliminary exchange, determines an appropriate configuration that the terminal device can handle. This prevents the terminal device from being assigned impossible measurement tasks.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the terminal device performs CLI measurement for multiple network devices simultaneously, then comprehensive CLI monitoring is achieved, but the device's measurement resources are exceeded

Engineering Contradiction:
ImproveCLI measurement coverageVSAvoidmeasurement resources
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting the CLI measurement configuration parameters based on the terminal device's capabilities and the network conditions. The first network device receives configuration information from the second network device and modifies the measurement parameters (such as measurement bandwidth, reporting frequency, or resource allocation) to ensure the total measurement load does not exceed the terminal device's resources while still achieving comprehensive CLI monitoring coverage.

Inventive Principle:
Principle #35Parameter changes

AI summary

Example cross-link interference (CLI) measurement configuration methods and apparatus are described. In one example method, a first network device receives, from a second network device, a first message that indicates information about a CLI measurement. The first network device configures the CLI measurement for a terminal device based on the first message.
