Solution Overview

Problem

The flexibility of channel transmission in current New Radio (NR) systems is limited due to terminal device transmission power constraints, necessitating more flexible channel transmission methods.

Innovation Solution

The method involves dynamically selecting time units for channel transmission, allowing transmission across multiple time units to enhance flexibility, especially when power is limited, by using time unit aggregation and ensuring constraints on available resources and priorities are met.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If terminal device uses fixed time unit for channel transmission, then transmission process is simple, but channel transmission flexibility is poor

Engineering Contradiction:
Improvechannel transmission flexibilityVSAvoidtransmission process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by enabling the terminal device to dynamically select time units for channel transmission based on constraint conditions. Instead of using fixed time units, the system allows flexible determination of time units (singular or multiple) according to available physical resources and channel priorities, thereby improving adaptability while managing complexity through structured selection criteria.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of time unit selection from fixed to variable. The terminal device determines whether to use one or multiple time units based on constraint conditions such as available physical resources and channel priorities. This parameter change enables flexible adaptation to different transmission scenarios while maintaining systematic control through defined selection rules.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If terminal device transmits channel on multiple time units, then channel transmission flexibility is improved, but transmission power requirement increases

Engineering Contradiction:
Improvechannel transmission flexibilityVSAvoidtransmission power
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent changes the transmission approach from single time unit to multiple time units based on constraint conditions. When physical resources are limited or channel priority is low, the system selects multiple time units with smaller resource allocations per unit, distributing the transmission power requirement across multiple instances rather than concentrating it in one high-power transmission.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent segments the channel transmission across multiple time units when constraint conditions are met. Instead of transmitting the entire channel in one time unit with high power, the transmission is divided into multiple segments across different time units, each with lower individual power requirements, thereby reducing peak power demands while maintaining overall transmission flexibility.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If terminal device dynamically selects time units, then channel transmission flexibility is enhanced, but resource allocation complexity increases

Engineering Contradiction:
Improvechannel transmission flexibilityVSAvoidresource allocation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent changes resource allocation from fixed to dynamic based on constraint conditions. The terminal device evaluates available physical resources and channel priorities to determine the number and type of time units for transmission. This dynamic parameter adjustment enhances flexibility while managing complexity through systematic evaluation criteria and structured decision-making processes.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality by allowing different time units to have different resource allocations and characteristics based on local constraint conditions. Each time unit can be selected or rejected independently based on whether it meets the constraint conditions, enabling localized optimization of resource allocation without requiring complex global coordination.

Inventive Principle:
Principle #3Local quality
