Solution Overview
Problem
Existing wireless communication systems lack explicit support for simultaneous multi-panel uplink (UL) transmission, limiting throughput and reliability improvements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If time domain multiplexing is used for PUSCH transmissions, then device complexity is reduced, but productivity is limited due to sequential transmission
Solution Approach 1:
The patent transitions from time domain multiplexing (sequential transmission in one dimension) to frequency domain multiplexing (parallel transmission across multiple frequency dimensions). By allocating different frequency resources to different antenna panels, the system enables simultaneous PUSCH transmissions, effectively moving from one-dimensional time-based scheduling to multi-dimensional time-frequency resource allocation, thereby increasing throughput without proportionally increasing device complexity
Solution Approach 2:
The patent segments the frequency spectrum into different frequency resources and assigns them to different antenna panels for simultaneous PUSCH transmission. This segmentation of frequency resources allows multiple panels to operate in parallel without interference, enabling the system to achieve higher productivity by dividing the transmission task across multiple spatial and frequency segments
2Reliability
If single-panel PUSCH transmission is used, then device complexity is minimized, but reliability is limited
Solution Approach 1:
The patent merges multiple antenna panels to transmit PUSCH simultaneously using different frequency resources. By combining the transmission capabilities of multiple panels in parallel, the system achieves higher reliability through diversity gain and improved signal robustness, while the frequency domain multiplexing framework keeps the overall system architecture manageable
3Productivity
If frequency domain multiplexing is implemented for simultaneous multi-panel PUSCH transmission, then productivity is enhanced, but device complexity increases
Solution Approach 1:
The patent creates a universal resource allocation framework that can handle both single-panel and multi-panel PUSCH transmissions. The frequency domain multiplexing mechanism is designed to be flexible and adaptable, allowing the system to dynamically allocate frequency resources based on the number of active panels and transmission requirements, thereby achieving high productivity while keeping device complexity manageable through a unified multi-functional architecture

AI summary
An apparatus of a user equipment (UE), the apparatus comprising a processor, and a memory storing instructions that, when executed by the processor, configure the apparatus to: receive, from a base station, scheduling information for scheduling a first physical uplink shared channel (PUSCH) transmission and a second PUSCH transmission which are at least partially overlapped in time domain; and in response to the scheduling information, perform the first PUSCH transmission through a first antenna panel and the second PUSCH transmission through a second antenna panel by using mutually different frequency-domain resources.
