Uplink Control Information Resource Allocation in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently transmitting and receiving uplink control information between terminals and base stations, particularly when various numerologies are applied, leading to increased signaling overhead and complexity in resource allocation.
Innovation Solution
The method involves dynamically allocating PUCCH resources for uplink control information transmission, allowing for flexible configuration based on specific situations, such as combining HARQ-ACKs for multiple DL slots into a single PUCCH resource, and using implicit and explicit indications for PUCCH resource allocation to reduce overhead and improve resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate PUCCH resources are allocated for each DL slot, then HARQ-ACK feedback reliability is improved, but signaling overhead and resource allocation complexity increase
Solution Approach 1:
The patent combines multiple HARQ-ACK feedbacks from different DL slots into a single PUCCH resource. Specifically, when a UE receives downlink data in multiple slots with different numerologies, it multiplexes the HARQ-ACK information into one uplink transmission, reducing the number of separate PUCCH allocations needed while maintaining feedback reliability
Solution Approach 2:
The patent creates a universal PUCCH resource allocation mechanism that can handle multiple DL slots with different numerologies through a single resource configuration. The PUCCH resource is designed to carry aggregated HARQ-ACK information from various slot configurations, making the resource allocation system more versatile and less complex
2Adaptability or versatility
If multiple PUCCH resources are configured for different numerologies, then service adaptability is improved, but overhead increases
Solution Approach 1:
The patent merges the resource allocation for multiple numerologies into a unified PUCCH resource configuration. Instead of maintaining separate PUCCH resources for each numerology type, the system uses a single resource that can accommodate HARQ-ACK feedback from multiple numerologies, significantly reducing signaling overhead
Solution Approach 2:
The patent changes the parameters of the PUCCH resource to make it adaptable to different numerologies. By adjusting timing and frequency parameters of a single PUCCH resource, the system can serve multiple numerology configurations without creating additional resources, thus reducing overhead while maintaining adaptability
