PUCCH CSI Reporting Resource Reallocation for Timely Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in channel state information reporting due to insufficient available channel state information processing units, leading to decreased data throughput and potential outdated reports.
Innovation Solution
A method for a UE to allocate additional channel state information processing units by releasing previously occupied units based on predefined rules, ensuring sufficient resources for timely reporting, particularly for low-latency communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the UE uses the available channel state information processing units for computing channel state information, then the computing capacity is limited, but the reporting timeliness deteriorates when additional processing units are needed
Solution Approach 1:
The patent implements dynamic allocation of channel state information processing units by allowing the UE to release processing units from lower priority communications and reallocate them to higher priority communications on demand. This dynamic adjustment enables the system to adapt processing unit availability to changing communication priorities, resolving the contradiction between limited processing units and timely reporting requirements.
Solution Approach 2:
The patent changes the parameter of processing unit availability by introducing a mechanism to release and reallocate processing units based on communication priority. When a high-priority communication requires channel state information reporting, the system changes the state of processing units from occupied to available by releasing them from lower priority tasks, thereby increasing the effective number of processing units without adding hardware resources.
2Productivity
If the UE allocates processing units to multiple communications concurrently, then resource utilization improves, but the ability to provide timely reports for low-latency communications deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different communications based on their priority levels. High-priority communications receive preferential access to processing units through the release and reallocation mechanism, while lower-priority communications can tolerate delays. This localized quality adjustment ensures that critical low-latency communications maintain reliable timeliness while overall resource utilization remains high.
Solution Approach 2:
The patent implements a feedback mechanism where the UE monitors communication priorities and adjusts processing unit allocation accordingly. When low-latency communication requirements are detected, the system provides feedback by releasing processing units from lower priority tasks and reallocating them to high-priority tasks, ensuring that timeliness requirements are met while maintaining efficient resource utilization.
3Quantity of substance
If the UE releases processing units from ongoing computations, then available processing units increase, but the computational work already in progress may be interrupted
Solution Approach 1:
The patent applies preliminary action by establishing priority-based processing unit allocation rules in advance. Instead of ad-hoc decisions about when and what to release, the system pre-configures priority levels and release criteria for different communications. This preliminary setup simplifies the real-time decision-making process, reducing management complexity while ensuring adequate processing units are available for high-priority low-latency communications.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. A receiving device (such as user equipment (UE)) may receive a downlink grant including an indication to report channel state information. The receiving device may identify, based on the downlink grant, a number of channel state information processing units associated with reporting the channel state information, and may determine that an available number of channel state information processing units is less than the number of channel state information processing units. In some cases, the receiving device may allocate, based on the determining, a set of channel state information processing units including the available number of channel state information processing units and one or more additional channel state information processing units. The receiving device may then transmit the channel state information report based on the set of channel state information processing units.
