Solution Overview

Problem

Current uplink transmission schemes in multi-TRP systems are limited by the inability of user equipment (UE) to simultaneously transmit multiple uplink transmissions to different transmission/reception points (TRPs), leading to inefficient utilization of time-frequency resources and impaired system efficiency.

Innovation Solution

The proposed solution involves a wireless communication method where a user equipment (UE) receives multiple uplink scheduling instructions and performs simultaneous uplink transmissions using multiple transmit panels, allowing for concurrent transmission to different TRPs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the UE transmits multiple uplink transmissions sequentially using a single transmit panel, then the transmission can be performed with existing hardware limitations, but the time-frequency resources are inefficiently utilized and system capacity is impaired

Engineering Contradiction:

Improvesystem efficiencyVSAvoidtime-frequency resource utilization

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent introduces spatial dimensionality by enabling simultaneous transmissions across multiple transmit panels (first transmit panel and second transmit panel) rather than sequential transmissions. This dimensional transition from time-sequential to space-parallel execution allows concurrent uplink transmissions to different TRPs, thereby improving time-frequency resource utilization and system capacity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the uplink transmission function into multiple independent transmission paths by configuring separate transmit panels. Each panel can independently transmit to different TRPs simultaneously, dividing the transmission task into parallel segments that execute concurrently, thus resolving the resource utilization bottleneck.

Inventive Principle:

Principle #1Segmentation

2Productivity

If the UE uses multiple transmit panels for simultaneous uplink transmissions, then time-frequency resource utilization is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by configuring the UE with multiple transmit panels that can be selectively activated for different transmission scenarios. The same UE device can serve multiple TRPs simultaneously using different panels, making the transmit system universally applicable to various multi-TRP communication configurations without requiring separate dedicated hardware for each TRP connection.

AI summary

A user equipment (UE) executes a wireless communication method. A set of transmission/reception points (TRPs) transmits first uplink scheduling and a second uplink scheduling to the UE. The UE receives a first uplink scheduling and a second uplink scheduling and performs a first uplink transmission using the first uplink scheduling and a second uplink transmission using the second uplink scheduling. The first uplink transmission and the second uplink transmission are simultaneously transmitted via multiple transmit panels.
