Uplink Control Information Multiplexing Timeline for Multi-Slot PUSCH
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently multiplexing uplink control information (UCI) across multiple slot transmissions, leading to suboptimal resource allocation and interference management.
Innovation Solution
A method and apparatus that apply a processing timeline for multiplexing UCI in at least one slot of a multiple slot physical uplink shared channel (PUSCH) transmission, allowing for flexible resource allocation and interleaving based on the type of transmission occasion, whether contiguous or non-contiguous, to optimize UCI multiplexing with PUSCH.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UCI is multiplexed across multiple slot PUSCH transmissions, then resource utilization improves, but processing complexity and timeline management worsen
Solution Approach 1:
The patent segments the UCI multiplexing process into distinct processing stages corresponding to different slot types (first slot vs. second slot). Each slot type has its own specific processing timeline and multiplexing rules, allowing the system to handle complex multi-slot UCI transmission by breaking it down into manageable per-slot operations with different timeline requirements.
2Productivity
If flexible resource allocation is applied based on transmission occasion type, then UCI multiplexing efficiency improves, but system complexity worsens
Solution Approach 1:
The patent applies different processing timelines and multiplexing strategies tailored to specific slot types. First slots use one timeline configuration while second slots use another, allowing each slot type to be optimized for its specific characteristics. This local customization improves UCI multiplexing efficiency for each slot type while managing overall system complexity through structured differentiation.

AI summary
A method, a computer-readable medium, and an apparatus are provided for wireless communication. The apparatus applies a processing timeline for multiplexing uplink control information (UCI) in at least one slot of a multiple slot physical uplink shared channel (PUSCH) transmission. The apparatus transmits the multiple slot PUSCH transmission with multiplexed UCI based on the processing timeline being satisfied.
