Solution Overview

Problem

Current uplink transmission methods lack clear definitions for processing time requirements when multiplexing uplink control information on physical uplink control channels (PUCCHs) or physical uplink shared channels (PUSCHs with different priorities, leading to unclear behaviors in existing systems.

Innovation Solution

The proposed method involves a terminal performing specific operations based on priority and timing conditions, such as multiplexing or not multiplexing uplink control information on channels with higher priorities, to improve reliability by adhering to defined processing time requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If uplink control information is multiplexed on channels with different priorities, then transmission efficiency is improved, but processing time requirements become unclear and reliability deteriorates

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidreliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies parameter changes by introducing priority levels (first priority, second priority, third priority) for different channels and defining specific processing time requirements based on these priority parameters. When a first channel overlaps with a second channel, or a second channel overlaps with a third channel, the terminal determines whether to multiplex uplink control information based on the priority parameters and corresponding processing time thresholds, thereby resolving the contradiction between transmission efficiency and reliability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamics by making the multiplexing decision adaptive rather than static. The terminal dynamically determines whether to multiplex uplink control information on the third channel based on real-time conditions: the priority relationships between overlapping channels and whether the processing time meets the required threshold. This dynamic approach allows the system to optimize transmission efficiency while maintaining reliability under varying channel conditions

Inventive Principle:
Principle #15Dynamics

2Device complexity

If processing time requirements are not clearly defined, then system complexity is reduced, but transmission reliability deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoidtransmission reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies segmentation by dividing the channel overlap scenario into distinct segments with clear boundaries: (1) first channel overlapping second channel, (2) second channel overlapping third channel, and (3) the decision point for multiplexing on the third channel. Each segment has clearly defined priority relationships and processing time requirements, which reduces system complexity by providing structured decision rules while ensuring transmission reliability through explicit thresholds

Inventive Principle:
Principle #1Segmentation

3Productivity

If uplink control information is always multiplexed on highest priority channel, then transmission efficiency is improved, but processing time constraints may be violated

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidprocessing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by requiring the terminal to perform a preliminary check of the processing time before multiplexing uplink control information on the third channel. The terminal first determines whether the processing time meets the required threshold based on channel priorities, and only then proceeds with multiplexing if the condition is satisfied. This preliminary verification ensures that transmission efficiency is improved through multiplexing while processing time constraints are not violated

Inventive Principle:
Principle #10Preliminary action

AI summary

An uplink transmission method includes that in a case that a first channel overlaps a second channel in time, the second channel overlaps a third channel in time, and a priority corresponding to the third channel is higher than a priority corresponding to the first channel and a priority corresponding to the second channel, a terminal performs a first operation. The first operation includes: multiplexing first uplink control information on the third channel for transmission; or not multiplexing the first uplink control information on the third channel for transmission. The first uplink control information is uplink control information carried on the first channel.
