Solution Overview

Problem

The existing RF system architecture in 5G mobile communication devices faces challenges in optimizing sensitivity and reducing insertion loss, particularly in the 5G NR system requiring four antenna groups, which affects data transmission performance.

Innovation Solution

The implementation of a transmitting module and receiving module with integrated channel selector-switches and signal transmit-receive processing circuits, along with a method for antenna switching, optimizes the RF system architecture by reducing insertion loss and improving channel sensitivity through higher integration and efficient antenna grouping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If devices are separated in the RF system architecture, then device functionality is maintained, but insertion loss increases and sensitivity decreases

Engineering Contradiction:
Improveinsertion lossVSAvoiddevice separation
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent merges the channel selector switch and signal processing circuit into an integrated module that is disposed adjacent to the antenna group. This integration reduces the number of separate devices and connections in the RF signal path, thereby reducing insertion loss while maintaining all necessary functionality for channel selection and signal processing.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If devices are integrated closer to antenna groups, then sensitivity improves and insertion loss reduces, but manufacturing complexity increases

Engineering Contradiction:
Improvechannel sensitivityVSAvoidintegration complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent segments the RF system into distinct functional modules, with each transmitting module or receiving module integrated adjacent to a specific antenna group. This modular segmentation allows for optimized signal paths and improved sensitivity while maintaining manageable manufacturing complexity through standardized module designs that can be independently developed and tested.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If four antenna groups are supported in 5G NR system, then communication capability is enhanced, but system complexity and power consumption increase

Engineering Contradiction:
Improveantenna group supportVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by stationary object

Solution Approach 1:

The patent implements dynamic antenna switching capability where the channel selector switch can dynamically connect different antenna groups to different transmitting or receiving modules based on communication requirements. This dynamic configuration allows the system to support four antenna groups for enhanced communication capability while consuming power only for the actively used modules, rather than continuously powering all four antenna groups.

Inventive Principle:
Principle #15Dynamics
