Uplink Resource Segmentation for Reliable CG PUSCH UCI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In beyond-5G and -6G communications, the reliability of uplink transmissions is compromised due to UCI multiplexing on preconfigured resources, leading to decreased performance in CG PUSCH transmissions, especially with high reliability and varying data amounts.
Innovation Solution
A method for multiplexing UCI signaling on separate resources from data transmissions by configuring distinct first and second resources based on conditions such as UCI presence, priority, and resource overlap, using techniques like transport block repetition and priority-based resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If preconfigured resources are used for periodic data transmission, then transmission efficiency is improved, but transmission reliability deteriorates due to UCI multiplexing
Solution Approach 1:
The patent segments the uplink resources into first resources for data transmission and second resources for UCI transmission. By dividing the resource allocation into separate domains (first resources and second resources), the system eliminates the conflict between data and control information, thereby maintaining both transmission efficiency and reliability.
Solution Approach 2:
The patent introduces an intermediary mechanism where the network node determines and signals resource allocation based on conditions (such as UCI presence, priority, and overlap). This intermediary control layer coordinates between data transmission and UCI transmission, resolving conflicts and ensuring reliable operation.
2Adaptability or versatility
If UCI multiplexing is performed on CG PUSCH, then resource utilization is improved, but transmission reliability decreases
Solution Approach 1:
The patent segments resource allocation into distinct first resources for data and second resources for UCI. This segmentation allows the system to maintain high resource utilization while ensuring reliability, as each resource type is allocated separately without mutual interference.
Solution Approach 2:
The patent implements dynamic resource determination based on conditions (UCI presence, priority, overlap). The network node dynamically selects between first resources and second resources according to real-time requirements, optimizing both resource utilization and reliability adaptively.
3Loss of time
If preconfigured resources are allocated for periodic transmission, then latency is reduced, but reliability is compromised due to UCI multiplexing constraints
Solution Approach 1:
By segmenting resources into first resources for data and second resources for UCI, the patent eliminates the reliability issues associated with UCI multiplexing on preconfigured resources. This allows periodic transmission to maintain both low latency and high reliability.
Solution Approach 2:
The patent uses preliminary resource configuration where the network node pre-determines resource allocation based on conditions. This preliminary action enables efficient periodic transmission while ensuring reliability is maintained through pre-planned resource separation.
Data Source
AI summary
A wireless communication method for use in a wireless terminal is disclosed. The method comprises receiving, from a wireless network node, a control signaling comprising resource configuration information associated with one or more first data transmission resources, determining first resources in the one of a plurality of the first data transmission resources and/or second resources in the one of the plurality of the first data transmission resources based on a first condition, and transmitting, to the wireless network node, at least one of: data on the first resources, an uplink control information, UCI, signaling on the second resources, or data and an uplink control information, UCI, signaling on the second resources.
