RTS Frame Feedback Resource Configuration for Multi-Band Wi-Fi
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in next-generation Wi-Fi networks, the existing methods for transmitting receipt feedback information face challenges in ensuring timely and accurate feedback due to the limited time available for data frame decoding, leading to potential errors in acknowledging data frames across multiple transmission bands.
Innovation Solution
The method involves generating and sending a Request To Send (RTS) frame that includes feedback resource information, allowing the data frame receiver to indicate the transmission resource for sending receipt feedback information, which can be in a specific band or time interval, thereby providing sufficient time for decoding and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data frame transmission is performed in multiple transmission bands simultaneously, then transmission speed and throughput are improved, but the time available for decoding at the receiver is insufficient leading to feedback errors
Solution Approach 1:
The patent applies preliminary action by including feedback resource information in the RTS frame before data transmission begins. This allows the receiver to pre-configure the feedback transmission resource, ensuring that sufficient time is allocated for decoding before the feedback deadline, thus resolving the contradiction between high throughput and feedback accuracy.
2Loss of time
If feedback resource information is included in the RTS frame, then feedback transmission timing is improved, but frame structure complexity increases
Solution Approach 1:
The patent merges the feedback resource information with the existing RTS frame structure rather than creating a separate feedback configuration mechanism. This combining approach improves feedback timing while minimizing the increase in frame structure complexity, as the additional information is integrated into the already-established RTS protocol.
Data Source
AI summary
Methods, apparatuses, communication devices and storage media for configuring transmission of receipt feedback information. A Request To Send (RTS) frame is generated in a case that a data frame is transmitted in a plurality of transmission bands. The RTS frame includes feedback resource information for indicating a transmission resource through which receipt feedback information is transmitted by a data frame receiver. And, the RTS frame is sent.
