Solution Overview

Problem

Current wireless communication systems face inefficiencies in processing protocol data units (PDUs) across multiple transmission time intervals (TTIs), particularly in aggregating descriptors for serial numbers (SNs) of PDUs, which affects processing efficiency and resource utilization.

Innovation Solution

A method and apparatus for wireless communication devices that receive PDUs in multiple TTIs, generate descriptors for each TTI identifying SNs, aggregate these descriptors into a single aggregated descriptor across multiple TTIs, and process PDUs based on this aggregated information, optimizing resource usage and processing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If descriptors are generated for each TTI separately, then processing accuracy for individual TTIs is maintained, but processing complexity and resource consumption increase

Engineering Contradiction:

Improveprocessing accuracyVSAvoidprocessing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines descriptors from multiple TTIs into a single aggregated descriptor that covers a range of serial numbers across TTIs. This merging approach maintains the necessary tracking accuracy while reducing the total number of descriptors that need to be processed, thereby lowering processing complexity and resource consumption.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If descriptors are aggregated across multiple TTIs, then processing efficiency improves, but memory requirements increase

Engineering Contradiction:

Improveprocessing efficiencyVSAvoidmemory requirements

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent segments the aggregated descriptor into manageable components, organizing serial number ranges in a structured format. This segmentation allows efficient storage and processing of the aggregated information without requiring excessive memory resources, as the data is organized in a compact and accessible manner.

Inventive Principle:

Principle #1Segmentation

3Use of energy by moving object

If individual descriptors are processed for each TTI, then resource utilization is higher, but processing speed decreases

Engineering Contradiction:

Improveresource utilizationVSAvoidprocessing speed

Core Design Contradiction:

Use of energy by moving objectVSSpeed

Solution Approach 1:

The patent performs preliminary aggregation of descriptors from multiple TTIs into a single descriptor before processing. This preliminary action consolidates the data structure, enabling faster subsequent processing operations while maintaining efficient resource utilization, as the system processes fewer, more compact data structures.

Inventive Principle:

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive protocol data units (PDUs) in multiple TTIs (e.g., slots). The wireless communication device may generate, for each TTI of the multiple TTIs, a descriptor that identifies serial numbers (SNs) of PDUs that are received in the TTI. The wireless communication device may aggregate the descriptors for the multiple TTIs into an aggregated descriptor that identifies the SNs of the PDUs across the multiple TTIs. The wireless communication device may process the PDUs received in the multiple TTIs based at least in part on the aggregated descriptor. Numerous other aspects are described.
