Solution Overview

Problem

In new radio (NR) systems, determining the appropriate transmission parameters for different channels and information is challenging, as existing methods do not effectively manage the selection of uplink control information and channels based on varying transmission parameters, leading to inefficient resource allocation and potential delays.

Innovation Solution

A method where terminal devices determine the channel and information to be transmitted in a time unit based on the transmission parameters of uplink control information and uplink channels, allowing for the selection of a reasonable channel and information for transmission, and potentially multiplexing uplink channels to save resources, by comparing transmission time intervals and subcarrier spaces.

If the same transmission parameters are used for different channels and information, then device complexity is reduced, but resource allocation efficiency deteriorates

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent segments transmission parameters into different categories (time domain parameters, frequency domain parameters, power parameters) and assigns different parameter sets to different channel types (PUCCH, PUSCH, random access channels). This segmentation allows efficient resource allocation while maintaining manageable complexity through structured parameter groups.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent dynamically changes transmission parameters based on channel type, traffic conditions, and resource availability. Different parameters are selected from predefined sets depending on the specific transmission scenario, enabling optimal resource allocation without requiring complex real-time calculations.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If different transmission parameters are used for different channels and information, then resource allocation efficiency is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent creates a universal transmission parameter framework that can be applied across multiple channel types and information types. The same parameter selection mechanisms and resource allocation procedures work for control channels, data channels, and random access channels, reducing the need for channel-specific complex logic.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If transmission parameters are not optimized, then device complexity is reduced, but transmission delays increase

Engineering Contradiction:

Solution Approach 1:

The patent pre-configures transmission parameter sets and resource allocations before actual data transmission is needed. Parameter sets are prepared in advance based on channel characteristics and traffic patterns, enabling immediate transmission without complex real-time optimization calculations, thus reducing delays while maintaining efficiency.
