Solution Overview

Problem

In communications technologies, terminals equipped with multiple transceivers often experience interference at neighboring or harmonic frequencies, leading to poor communication performance.

Innovation Solution

A sending method and interference handling method are introduced, where a terminal sends first information to a network-side device indicating the type of each transmission time position in a transmission period, and the network-side device adjusts information related to the transmission time position based on this information to reduce interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a terminal is equipped with multiple transceivers supporting different RATs, then the terminal's communication capability and versatility are improved, but interference occurs at neighboring or harmonic frequencies leading to poor communication performance

Engineering Contradiction:
Improvecommunication capabilityVSAvoidinterference
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the transmission period into different transmission time positions (first, second, third positions) with different interference characteristics. Each position is handled separately with specific sending strategies, allowing the system to address interference at different frequency bands independently while maintaining overall communication capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic adjustment of sending strategies based on real-time interference conditions. The network-side device determines whether to send data at each transmission time position based on interference information, and the terminal dynamically adjusts its receiving operations. This dynamic approach allows the system to adapt to changing interference patterns while maintaining versatility.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the terminal sends detailed information about transmission time positions to the network-side device, then the network-side device can adjust to reduce interference, but the signaling overhead and processing complexity increase

Engineering Contradiction:
Improvecommunication performanceVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts only the essential interference information needed for network-side adjustment. Instead of transmitting complete transmission schedules, the terminal sends specific indication information about transmission time positions and their interference characteristics. This extraction approach reduces signaling overhead while providing sufficient information for the network-side device to make appropriate adjustments.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the parameter representation of interference information from detailed transmission schedules to condensed indication information about transmission time positions. This parameter transformation reduces the amount of data that needs to be processed and transmitted, thereby reducing complexity while maintaining the ability to improve communication performance.

Inventive Principle:
Principle #35Parameter changes
