Solution Overview

Problem

In wireless communication systems, particularly NR systems, there is a challenge in determining and adhering to the maximum data rate supported by a terminal, as well as efficiently scheduling data transmission and reception to avoid exceeding this rate, especially in scenarios involving data communication between terminals.

Innovation Solution

A method and device that identify the maximum data rate supported by a terminal, determine an instant data rate based on the number of slots corresponding to one transport block, and perform data transmission or reception only if the condition that the maximum data rate is greater than or equal to the instant data rate is satisfied.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the base station schedules data transmission at high data rates to improve productivity, then the data transmission efficiency is improved, but the terminal may fail to process data exceeding its maximum data rate capability, leading to transmission failures

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoiddata transmission reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The terminal performs preliminary identification of its maximum data rate capability before data transmission begins. The base station uses this pre-identified maximum data rate information to perform preliminary scheduling decisions, ensuring that scheduled data rates do not exceed terminal capabilities, thus preventing transmission failures before they occur

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal provides feedback to the base station about its maximum data rate capability. The base station uses this feedback information to adjust scheduling decisions, ensuring that data transmission rates remain within the terminal's processing capabilities while maximizing transmission efficiency

Inventive Principle:

Principle #23Feedback

2Productivity

If the base station performs aggressive data scheduling to increase productivity, then more data is transmitted, but the terminal cannot handle data exceeding its processing capability, causing operation failures

Engineering Contradiction:

Improvedata scheduling efficiencyVSAvoidterminal data handling capability

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The scheduling decisions are based on dynamic parameter adjustment where the maximum data rate parameter is identified and used to constrain scheduling. The base station adjusts scheduling parameters (data rate, resource allocation) to match the terminal's identified maximum data rate capability, ensuring operations remain within feasible limits

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If data transmission is performed without verifying maximum data rate capability, then transmission operations can proceed freely, but data exceeding terminal capability cannot be properly received or processed

Engineering Contradiction:

Improvedata transmission flexibilityVSAvoiddata rate matching precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces trial-and-error transmission attempts with a calculated approach based on identified maximum data rate parameters. Instead of attempting transmissions and handling failures, the system uses parameter-based scheduling that substitutes mathematical calculation for mechanical trial-and-error, achieving precise data rate matching

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
