Multi-Link Communication Feedback for Flexible Acknowledgment Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing acknowledge rule in multi-link communication systems requires receiving status of data units to be fed back through the same link, which is too strict and violates scenarios where data is transmitted across multiple links, leading to inefficiencies and rule violations.
Innovation Solution
The proposed method allows receiving status information of data units to be fed back through different links based on specific conditions, such as sequence numbers and scoreboard ranges, adapting to various acknowledge policies to avoid rule violations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the acknowledge rule requires receiving status to be fed back through the same link, then link-specific tracking is simplified, but adaptability to multi-link scenarios deteriorates
Solution Approach 1:
The patent segments the scoreboard into multiple link-specific scoreboards, where each link maintains its own scoreboard for tracking data units. This allows the system to handle multi-link scenarios by dividing the tracking responsibility across separate link-specific structures, thereby improving adaptability while maintaining manageable complexity through organized segmentation.
Solution Approach 2:
The patent introduces a new dimension by allowing feedback to be sent through different links than the one used for data transmission. Instead of being constrained to a single link dimension, the system now operates in a multi-dimensional space where data can be sent on one link and acknowledged on another, greatly enhancing adaptability to various multi-link communication scenarios.
2Productivity
If the acknowledge rule is strictly enforced, then rule compliance is improved, but system efficiency deteriorates in multi-link scenarios
Solution Approach 1:
The patent implements dynamic acknowledge rule application by introducing conditions under which the strict same-link feedback requirement can be relaxed. The system dynamically adjusts the acknowledge behavior based on scoreboard state and link conditions, allowing feedback to be sent through alternative links when appropriate, thereby maintaining rule compliance while improving system efficiency in multi-link scenarios.
Solution Approach 2:
The patent changes the parameters of the acknowledge rule by introducing new variables such as link-specific scoreboards and conditional feedback paths. Instead of a fixed parameter requiring same-link feedback, the system now uses configurable parameters that allow flexible determination of feedback paths based on current system state, improving both efficiency and adaptability.

AI summary
This application provides a communication method and an apparatus, and relates to the field of communications technologies, to reduce a phenomenon that an acknowledge rule is violated in some scenarios. The method includes: After a receive device receives a first data unit from a transmit device through a first link, the receive device sends receiving status information of the first data unit to the transmit device through the first link, unless the first data unit meets any one of a first preset condition. The first preset condition includes: Correctly received information of the first data unit is fed back through another link, or an acknowledge policy corresponding to the first data unit is no acknowledge. The communication method in embodiments of this application is applied to a multi-link data transmission process.
