Multi-Link Device and Method for Supporting Block Acknowledgement Mechanism
Summary
TP-Link Systems Inc. filed patent application US20260113165A1 for a Multi-Link Device (MLD) Block Acknowledgement mechanism that manages data frame transmission across multiple wireless links. The invention covers a recipient MLD configured to receive and deliver data frames according to a diversity MLD BA scheme, where duplicated sets of data are transmitted simultaneously across established links. The application was filed on 2024-10-21 under application number 18921792.
About this source
USPTO classification H04L covers transmission of digital information: network protocols, modulation schemes, wireless signal processing, coding, encryption in transit, and multiplexing. With 5G, 6G, and satellite internet driving new filings, H04L is one of the largest active patent classes. Every newly published application in H04L lands in this feed, around 215 a month. Applications publish 18 months after filing, so this feed reveals what MediaTek, Qualcomm, Ericsson, Samsung, Huawei, and dozens of smaller companies were working on in the prior year and a half. Watch this if you compete in networking hardware, advise telecoms on IP strategy, or scout acquisition targets in wireless infrastructure.
What changed
TP-Link Systems Inc. filed USPTO patent application US20260113165A1 covering a Multi-Link Device Block Acknowledgement (BA) scheme for managing data frame transmission across multiple wireless links between MLDs. The invention describes a recipient MLD with processors and memory configured to receive BA scheme indications from an originator MLD and deliver received data frames across multiple established links according to a diversity MLD BA protocol. CPC classifications include H04L 5/0055 and H04W 76/15, indicating relevance to wireless communication standards.
Technology companies developing Wi-Fi 7 or multi-link operation compliant devices should monitor this intellectual property filing for potential licensing implications or freedom-to-operate considerations.

Abstract
A recipient Multi-Link Device (MLD) including one or more processors; a memory coupled to at least one of the processors; and a set of computer program instructions stored in the memory, which, when executed by at least one of the processors, perform actions of: receiving, from an originator MLD, an indication for indicating a MLD Block Acknowledgment (BA) scheme; and delivering, in response to the HOL support indication indicating a diversity MLD BA scheme of transmitting duplicated sets of data frames on multiple links established between the recipient and originator MLDs, received data frames of a plurality of data frames from a first layer to a second layer of the recipient MLD according to the diversity MLD BA scheme, wherein the second layer is higher than the first layer.
