Three-Port PUSCH Transmission for Improved Uplink Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physical uplink shared channel (PUSCH) transmission designs do not support user equipment (UE) with three transmit ports, leading to impaired uplink transmission performance.
Innovation Solution
A method for PUSCH transmission with three transmit ports, where a UE reports its capability to support three transmit ports to a base station, and the base station configures the UE with a PUSCH transmission using these ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the current PUSCH mechanism is used with two transmit ports or four transmit ports with zero value in the last term, then the system can maintain compatibility with existing designs, but the uplink transmission performance is greatly impaired
Solution Approach 1:
The patent changes the parameter of supported transmit port configurations from {2, 4} to include 3, by modifying the PUSCH mechanism to accommodate three transmit ports with non-zero values in all terms of the precoding matrix, thereby resolving the contradiction between existing compatibility and new capability support
Solution Approach 2:
The patent extends the PUSCH mechanism to be universal by enabling it to support multiple transmit port configurations (2, 3, and 4 ports) within the same framework, allowing the system to adapt to different UE capabilities while maintaining a unified transmission mechanism

AI summary
A method of physical uplink shared channel (PUSCH) transmission with three transmit ports, by a user equipment (UE) includes reporting to a base station that the UE supports three transmit ports for one PUSCH transmission and being configured by the base station with the one PUSCH transmission with the three transmit ports.
