Multi-Panel UCI Multiplexing on Overlapping PUSCH Transmissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks do not support mechanisms for multiplexing uplink control information (UCI) on physical uplink shared channel (PUSCH) transmissions when they overlap with physical uplink control channel (PUCCH) transmissions, leading to potential communication failures.
Innovation Solution
A method and system for a user equipment (UE) with multiple antenna panels to multiplex UCI on PUSCH transmissions directed towards multiple transmission/reception points (TRPs), using schemes like FDM and SDM, to avoid resource collisions and improve communication reliability and efficiency.

Engineering Contradiction Analysis
1Productivity
If simultaneous PUSCH and PUCCH transmissions are performed toward multiple TRPs, then communication efficiency and productivity are improved, but resource collisions and communication failures occur due to lack of UCI multiplexing support
Solution Approach 1:
The patent merges UCI transmission with PUSCH transmission by multiplexing UCI on the PUSCH resource elements. This combines two previously separate transmission functions (PUCCH and PUSCH) into a unified transmission mechanism, allowing simultaneous operation without resource collisions when transmissions overlap in time toward multiple TRPs.
Solution Approach 2:
The PUSCH transmission is enhanced to serve multiple functions: it carries both data and UCI information. By making PUSCH universal (able to carry both data and control information), the system eliminates the need for separate PUCCH transmissions, thereby avoiding resource collisions while maintaining communication reliability and efficiency.
2Reliability
If UCI multiplexing is implemented on PUSCH transmission, then resource collisions are avoided and communication reliability is improved, but device complexity increases due to additional multiplexing processing requirements
Solution Approach 1:
The patent segments the PUSCH resource elements into different portions: some resource elements are allocated for data transmission while others are allocated for UCI multiplexing. This segmentation allows the system to handle UCI and data transmission separately within the same PUSCH resource, reducing processing complexity by providing clear separation of functions rather than requiring complete redesign of the transmission mechanism.

AI summary
Disclosed is a method is performed by a user equipment (UE). The method includes configuring a physical uplink shared channel (PUSCH) transmission that comprises a first resource associated with a first antenna panel and a second resource associated with a second antenna panel, wherein the first antenna panel is directed toward a first transmission/reception point (TRP) and the second antenna panel is directed toward a second TRP. The method also includes determining that the PUSCH transmission overlaps in time with a physical uplink control channel (PUCCH) transmission toward at least one of the first TRP or the second TRP. The method also includes multiplexing uplink control information (UCI) associated with the PUCCH transmission on the PUSCH transmission.
