Dynamic Acknowledgment Configuration in Wireless MAC Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for wireless communication face inefficiencies due to large acknowledgement messages that exceed necessary network bandwidth and require devices to consult databases for varying block acknowledgment lengths, leading to suboptimal use of network resources.
Innovation Solution
The solution involves allowing the transmitter to define acknowledgment configurations within the data message itself, enabling dynamic adjustment of acknowledgment lengths and including multi-TID acknowledgment messages to efficiently manage acknowledgments, thereby reducing the need for extensive database lookups and optimizing network bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If block acknowledgment negotiation is performed during initial setup, then acknowledgment coverage for multiple MPDUs is enabled, but acknowledgment message length exceeds necessary bandwidth when PPDU size is small
Solution Approach 1:
The patent implements dynamic acknowledgment configuration by allowing the transmitter to define the acknowledgment configuration in each data message rather than using a fixed pre-negotiated setting. This enables the acknowledgment message length to adapt to the actual PPDU size, covering multiple MPDUs when necessary while avoiding excessive length when PPDU is small, thus resolving the contradiction between reliable acknowledgment coverage and bandwidth efficiency.
2Ease of manufacture
If pre-negotiated block acknowledgment configuration is used, then initial setup is simplified, but devices must consult databases for varying acknowledgment lengths among multiple devices
Solution Approach 1:
The patent enables each data message to carry its own acknowledgment configuration definition, making the message self-describing. This eliminates the need for devices to maintain and consult external databases about acknowledgment lengths for different devices, as all necessary configuration information is embedded directly in the data message itself, thereby reducing device complexity while maintaining ease of operation.
3Ease of operation
If fixed block acknowledgment length is negotiated, then negotiation process is straightforward, but network bandwidth is not optimized when actual data size varies
Solution Approach 1:
The patent allows the acknowledgment configuration parameters to be dynamically defined in each data message based on the actual PPDU size and data requirements. This enables the system to maintain simple operation by keeping the negotiation process straightforward while simultaneously optimizing network bandwidth utilization by adjusting acknowledgment message length to match the actual data being transmitted, resolving the contradiction between operational simplicity and productivity.

AI summary
Methods, apparatus, and systems disclosed provide for the configuration of acknowledgments of data. In some aspects, a method includes generating an aggregated media access control (MAC) protocol data unit (A-MPDU) frame, comprising a media access control protocol data unit (MPDUs), the media access control protocol data unit (MPDUs) comprising a media access control (MAC) header and data, wherein the media access control (MAC) header comprises an indication of an acknowledgment type for the data of the MPDU; and transmitting the A-MPDU onto a wireless network.
