Solution Overview

Problem

Existing mobile communication technologies face challenges in managing the transmission of diverse services like eMBB and URLLC, where time domain resources overlap, leading to conflicts in uplink channel characteristics and differing reliability requirements.

Innovation Solution

A method and apparatus for information transmission that utilize target power control parameters to manage overlapping physical uplink channels, such as PUCCH and PUSCH, by configuring proper transmit power for multiplexed uplink information, ensuring reliability for high-reliability services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple physical uplink channels are transmitted simultaneously with overlapping time domain resources, then the transmission capacity and service diversity are improved, but the reliability of high-reliability services deteriorates due to power conflicts and channel characteristic conflicts

Engineering Contradiction:
Improvetransmission capacityVSAvoidreliability of high-reliability services
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent changes the power control parameter from a single unified value to multiple service-specific values. Different power control parameters are assigned to different services (e.g., eMBB and URLLC) based on their reliability requirements. This parameter differentiation allows the system to maintain high transmission capacity while ensuring that high-reliability services receive appropriate power allocation, thus resolving the contradiction between productivity and reliability.

2Productivity

If different services share the same uplink channel resources, then the resource utilization efficiency is improved, but the channel characteristic conflicts and interference between services increase

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidchannel characteristic conflicts
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by assigning different power control parameters to different services within the same uplink channel resources. Instead of using a uniform transmission approach, the system tailors the power control characteristics locally to each service's requirements. This allows eMBB and URLLC services to coexist on the same resources while maintaining their respective channel characteristics and minimizing interference, thus resolving the contradiction between resource utilization efficiency and channel characteristic conflicts.

Inventive Principle:
Principle #3Local quality
