Uplink Control Information Transmission via Dynamic PUSCH Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in transmitting wireless signals, particularly in managing uplink control information and data simultaneously, leading to latency issues and suboptimal resource allocation.
Innovation Solution
A method and apparatus for a UE to acquire and utilize periodically allocated PUSCH resources for low-latency data transmission, while also transmitting uplink control information through either the first or second PUSCH, depending on availability, to efficiently manage resource allocation and reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If uplink control information is transmitted through periodically allocated PUSCH resources, then transmission latency is reduced, but resource allocation efficiency deteriorates when aperiodic resources are available
Solution Approach 1:
The patent implements dynamic resource selection by enabling the UE to adaptively choose between periodic and aperiodic PUSCH resources based on real-time channel conditions and traffic requirements. The system dynamically adjusts the transmission path by evaluating the availability and suitability of different PUSCH types, allowing optimal resource allocation that balances latency reduction with overall system efficiency.
2Adaptability or versatility
If aperiodically allocated PUSCH is used for control information transmission, then resource allocation flexibility is improved, but transmission latency increases
Solution Approach 1:
The patent employs preliminary action by pre-configuring periodic PUSCH resources in advance for uplink control information transmission. This ensures that dedicated low-latency resources are already available when control information needs to be transmitted, eliminating the need for on-the-fly resource allocation and reducing transmission delays while maintaining the option for aperiodic resources when flexibility is required.
3Productivity
If multiple PUSCH resources are allocated for different data types, then data transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing uplink resources into distinct periodic and aperiodic PUSCH allocations, each optimized for specific data types. Periodic PUSCH is designated for time-sensitive control information requiring low latency, while aperiodic PUSCH handles other data transmissions. This clear segmentation simplifies the selection logic at the UE, reducing processing complexity while maintaining high transmission efficiency for different data categories.

AI summary
The present invention relates to a wireless communication system and, more particularly, to a method and an apparatus therefor, the method comprising: a step of acquiring a periodically allocated PUSCH resource, wherein the periodically allocated PUSCH resource is used for a transmission of a first PUSCH; a step of performing a procedure for transmitting uplink control information if transmission of the uplink control information is required at the transmission timing of the first PUSCH; and a step of transmitting the uplink control information, wherein if an aperiodically allocated second PUSCH does not exist at the transmission timing of the first PUSCH, the uplink control information is transmitted via the first PUSCH, and if the aperiodically allocated second PUSCH exists at the transmission timing of the first PUSCH, the uplink control information is transmitted via the second PUSCH.
