UCI Multiplexing on Multi-Panel PUSCH for Overlapping Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in efficiently multiplexing uplink control information (UCI) on physical uplink shared channels (PUSCH) for multi-panel uplink transmissions, particularly when resource allocations overlap across different transmission occasions.
Innovation Solution
A method and apparatus for a user equipment (UE) to determine overlapping resource allocations for PUCCH and PUSCH transmission occasions, allowing for the multiplexing of UCI on a selected PUSCH transmission occasion, which can include either the first, second, or a combination of PUSCH transmission occasions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UCI is multiplexed on PUSCH for multi-panel uplink transmission, then resource utilization efficiency is improved, but resource allocation complexity increases due to overlapping time domain resources across multiple transmission occasions
Solution Approach 1:
The patent segments the overlapping PUSCH transmission occasions into distinct panels (first panel and second panel), where each panel is assigned specific time domain resources. This segmentation allows independent handling of each panel's resources while maintaining overall system efficiency, resolving the complexity of managing overlapping resources across multiple transmission occasions.
Solution Approach 2:
The patent introduces a panel dimension to differentiate between overlapping PUSCH transmissions. By assigning different panels to different time domain resources, the system transforms the problem from a one-dimensional time resource conflict into a multi-dimensional resource allocation problem, enabling efficient multiplexing without increasing complexity.
2Quantity of substance
If multiple PUSCH transmission occasions are allocated simultaneously, then uplink transmission capacity is improved, but interference management difficulty increases due to overlapping time domain resources
Solution Approach 1:
The patent applies local quality by assigning different time domain resource characteristics to different panels. Each panel has specific time domain resources allocated, creating localized resource quality differences that enable simultaneous transmissions while managing interference through differentiated resource allocation rather than uniform treatment.

AI summary
Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may determine that a resource allocation, for a physical uplink control channel (PUCCH) transmission occasion, indicates time domain resources that overlap time domain resources of a first resource allocation for a first physical uplink shared channel (PUSCH) transmission occasion and a second resource allocation for a second PUSCH transmission occasion; and multiplex uplink control information (UCI) associated with the PUCCH transmission occasion on a selected PUSCH transmission occasion, the selected PUSCH transmission occasion comprising at least one of the first PUSCH transmission occasion, the second PUSCH transmission occasion, or a combination thereof. Numerous other aspects are provided.
