Dynamic UCI Payload Sizing for PUSCH Resource Allocation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current wireless communication systems face challenges in efficiently allocating resources for transmitting uplink control information (UCI) and data in the physical uplink shared channel (PUSCH), particularly in 5G networks, where UCI payload sizes can be dynamic and vary significantly, leading to suboptimal resource allocation and degraded data throughput.

Innovation Solution

A method is introduced to determine the maximum supported payload size for UCI based on the total allocated resources and the minimum resources allocated for uplink data, allowing for dynamic adjustment of resource allocation to prioritize both UCI and data transmission in the PUSCH, ensuring efficient multiplexing and prioritization of resources.
