Solution Overview

Problem

Existing wireless communication technologies, such as NR R15, do not support the simultaneous transmission of two or more uplink physical channels or signals on a single carrier, leading to conflicts that exceed maximum transmission power or layer capabilities.

Innovation Solution

A method to resolve conflicts by determining priorities among overlapping uplink physical channels and signals, adjusting transmission powers or discarding lower-priority information to ensure simultaneous transmission on a single carrier, using a user terminal with a determining, acquiring, processing, and sending unit to manage conflicts based on characteristics like content type, time domain behavior, and number of ports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple uplink physical channels or signals are transmitted simultaneously on a single carrier, then transmission efficiency is improved, but transmission power exceeds maximum limits

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidtransmission power
Core Design Contradiction:
ProductivityVSPower

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting transmission power levels based on priority criteria. When multiple channels overlap in time domain, the system modifies power parameters to ensure total transmission power does not exceed maximum limits while still enabling simultaneous transmission of multiple channels.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamics by making transmission power adjustable rather than fixed. The system dynamically determines transmission power for each channel based on priority rules and real-time conditions, allowing flexible power allocation that adapts to different transmission scenarios.

Inventive Principle:
Principle #15Dynamics

2Productivity

If multiple uplink physical channels or signals are transmitted simultaneously on a single carrier, then transmission efficiency is improved, but transmission layers exceed maximum capabilities

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidtransmission layers
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by modifying transmission layer configurations based on priority criteria. When multiple channels overlap, the system changes layer parameters to ensure total layers do not exceed maximum capabilities while maintaining simultaneous transmission capability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamics by making transmission layer allocation flexible rather than fixed. The system dynamically determines which channels transmit on which layers based on priority rules, allowing adaptive layer allocation that prevents exceeding maximum layer limits.

Inventive Principle:
Principle #15Dynamics

3Power

If transmission power is reduced for lower priority channels, then power limits are respected, but communication reliability deteriorates

Engineering Contradiction:
Improvetransmission power complianceVSAvoidcommunication reliability
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-establishing priority criteria and power adjustment rules before transmission occurs. The system determines which channels should have reduced power based on predetermined priority rules, allowing proactive power management that balances compliance with reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by continuously monitoring transmission conditions and adjusting power levels accordingly. The system uses feedback mechanisms to ensure power reduction decisions maintain reliability by considering actual channel conditions and transmission requirements.

Inventive Principle:
Principle #23Feedback

AI summary

An information sending method, a user terminal and a computer-readable storage medium. The information sending method comprises: when an instruction for sending target information is detected, determining whether information in the target information has a conflict, wherein the target information comprises N physical channels and M physical signals, and M+N≥2; when the information in the target information has a conflict, acquiring the priority corresponding to the information in the target information; and according to the priority of the information in the target information, processing the target information and then sending same, wherein processing the target information comprises: adjusting the transmitted power of the information with low priority in the target information; or, discarding some or all of the pieces of information with low priority. The solution can realize the simultaneous sending of two or more uplink physical channels or signals on a single carrier.
