Network Coding and Multiplexing Configuration for Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks, particularly those using extended reality (XR), face inefficiencies in communication due to the lack of effective configurations for network coding (NC) and multiplexing.
Innovation Solution
The method involves configuring devices to receive and process multiplexing configurations for network-coded and non-network-coded logical channels, determining code block thresholds based on NC and multiplexing configurations, and implementing a hybrid automatic repeat request (HARQ) process that is aware of NC and multiplexing to optimize data transmission and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network coding and multiplexing are implemented in wireless communication networks, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the transmission process into network-coded logical channels and non-network-coded logical channels, allowing independent configuration and processing. This segmentation enables the system to handle different types of data differently, improving overall communication efficiency while managing complexity through structured organization.
Solution Approach 2:
The patent implements dynamic configuration of code block thresholds and HARQ processes based on network coding status and multiplexing requirements. The system adapts its parameters in real-time, adjusting thresholds and feedback mechanisms according to current transmission conditions, which optimizes efficiency without requiring fixed complex hardware designs.
2Reliability
If code block thresholds are determined based on NC and multiplexing configurations, then reliability is improved, but measurement precision requirements increase
Solution Approach 1:
The patent determines code block thresholds in advance based on configured network coding and multiplexing parameters, rather than measuring actual transmission conditions in real-time. This preliminary configuration approach allows the system to pre-establish reliable thresholds without requiring high-precision continuous measurement during data transmission.
Solution Approach 2:
The patent implements HARQ feedback mechanisms that provide information about transmission success or failure. This feedback loop allows the system to verify reliability through practical testing while using the feedback information to adjust future transmissions, reducing the need for extremely precise initial measurements.
3Productivity
If NC-aware and multiplexing-aware HARQ processes are configured, then communication efficiency is improved, but processing time increases
Solution Approach 1:
The patent segments the HARQ processing into separate handles for network-coded and non-network-coded logical channels. This segmentation allows parallel processing and independent optimization of each channel type, improving overall communication efficiency while minimizing the time required for processing by avoiding sequential handling of all channels.
Solution Approach 2:
The patent applies HARQ processing selectively based on the actual transmission requirements. When network coding is present, the system activates NC-aware processing only for those specific transmissions rather than processing all channels uniformly. This partial application approach optimizes efficiency for critical transmissions while reducing unnecessary processing time for channels that don't require enhanced treatment.
