Dynamic PUCCH Format Selection for Uplink Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current base station technologies employ static PUCCH formats for all UEs, leading to inefficient uplink and downlink performance due to inappropriate resource allocation, resulting in increased error rates during varying traffic conditions and wastage of computing and networking resources.
Innovation Solution
Implementing a dynamic selection mechanism for PUCCH formats based on uplink performance indicators and quality of service requirements, using a machine learning model to determine a total score that switches between short and long duration PUCCH formats, optimizing resource allocation and improving uplink performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static PUCCH formats are used for all UEs, then device complexity is reduced and ease of operation is improved, but uplink performance deteriorates and error rates increase under varying traffic conditions
Solution Approach 1:
The patent implements dynamic PUCCH format selection where the base station determines appropriate formats based on real-time uplink performance indicators and quality of service requirements. This allows the system to adapt to varying traffic conditions, resolving the contradiction between operational simplicity and uplink performance reliability.
Solution Approach 2:
The system changes the PUCCH format parameters dynamically based on traffic conditions and UE characteristics. By adjusting format parameters (such as duration and resource allocation) according to current network state, the system maintains ease of operation while improving uplink performance and reducing error rates.
2Reliability
If dynamic PUCCH format selection is implemented, then uplink performance is improved and error rates are reduced, but device complexity increases
Solution Approach 1:
The base station performs automatic PUCCH format selection based on uplink performance indicators and quality of service requirements without requiring complex UE-side decision-making. This self-service approach at the base station reduces overall system complexity while maintaining improved uplink performance through dynamic format adaptation.
3Use of energy by moving object
If static PUCCH formats are used, then computing resources are conserved, but resource allocation efficiency deteriorates and networking resources are wasted
Solution Approach 1:
The system dynamically changes PUCCH format parameters based on actual traffic conditions and quality of service requirements. This enables efficient resource allocation by matching resource consumption to actual needs, improving productivity while avoiding waste of computing and networking resources through inappropriate static allocations.

AI summary
A base station may receive uplink data identifying uplink performance indicators associated with user equipment connected to the base station, and may receive tuning factors associated with shared channel traffic received by the user equipment and quality of service requirements of the user equipment. The base station may determine a total score associated with utilizing a long duration physical uplink control channel (PUCCH) format for uplink control information based on the uplink data and the tuning factors. The base station may determine that the total score satisfies a threshold score and may switch to the long duration PUCCH format for the uplink control information based on the total score satisfying the threshold score. The base station may perform one or more actions based on switching to the long duration PUCCH format for the uplink control information.
