Terminal Device Frequency Switching for Multi-Band Transmission

Solution Overview

Problem

In wireless communication systems, terminal devices face increased hardware costs and power consumption when required to transmit data on multiple frequency points, as they need separate radio frequency transceiving units for each frequency point, leading to inefficiencies and interference issues.

Innovation Solution

A data transmission method where a terminal device receives indication information about multiple time domain resources with different frequency points, allowing it to perform data transmission on these resources without the need for multiple radio frequency transceiving units, by alternating or synchronizing data transmission based on specific frequency points, thereby reducing hardware and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the terminal device has two sets of independent radio frequency transceiving units to transmit data on two frequency points, then the capability to send and receive data on multiple frequency points is improved, but the hardware cost and power consumption increase

Engineering Contradiction:

Improvecapability to transmit data on multiple frequency pointsVSAvoidhardware cost

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the functionality of multiple radio frequency transceiving units into a single unit by implementing frequency switching in the time domain. The terminal device uses one radio frequency transceiving unit that alternates between different frequency points according to time domain resource allocations, combining what would traditionally require separate hardware units into a single multi-functional unit.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs periodic frequency switching where the terminal device alternates between different frequency points in a periodic manner based on configured time domain patterns. The network device configures periodic time domain resource allocations that dictate when the terminal should switch frequencies, creating a rhythmic switching pattern that enables multi-frequency operation with single hardware.

Inventive Principle:

Principle #19Periodic action

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent segments the data transmission in the time domain by dividing it into different time domain resources allocated to different frequency points. Instead of simultaneous transmission that causes interference, the transmission is segmented into non-overlapping time slots where each frequency point is active during its designated time period, eliminating interference while maintaining overall transmission capacity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs periodic frequency switching where the terminal device alternates between different frequency points in a periodic manner based on configured time domain patterns. The network device configures periodic time domain resource allocations that dictate when the terminal should switch frequencies, creating a rhythmic switching pattern that enables multi-frequency operation with single hardware.
