GROUP ADDRESSED FRAME DELIVERY OVER MULTI-LINK SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18236731 titled 'GROUP ADDRESSED FRAME DELIVERY OVER MULTI-LINK SYSTEMS

Simplified Explanation

The patent application relates to delivering frames over multi-link systems in a wireless network. It describes a method for an access point (AP) multilink device (MLD) to transmit data to a non-AP MLD over multiple communications links while ensuring that frames with identical data have identical sequence numbers (SN).

• The AP MLD identifies a first sequence number space (SNS) to be used for transmitting data over the first and second communications links.
• The MLD in the wireless network identifies the first SN based on the first SNS.
• The AP MLD transmits a frame containing the data to the non-AP MLD based on the first SN.

Potential applications of this technology:

• Wireless networks with multiple communications links can benefit from this technology to ensure consistent sequence numbering of frames with identical data.
• It can be used in scenarios where data needs to be transmitted over multiple links simultaneously, such as load balancing or redundancy purposes.

Problems solved by this technology:

• Ensures that frames with identical data have identical sequence numbers, preventing any confusion or inconsistencies in the receiving MLD.
• Facilitates efficient delivery of frames over multi-link systems, improving overall network performance and reliability.

Benefits of this technology:

• Simplifies the management and synchronization of sequence numbers in multi-link systems.
• Enhances the reliability and accuracy of frame delivery in wireless networks.
• Enables better utilization of multiple communications links, improving network efficiency.

Original Abstract Submitted

Embodiments may relate to group addressed frame delivery over multi-link systems. Systems and methods are configured for identifying, by an access point (AP) multilink device (MLD) in a wireless network, a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD over a first communications link and a second communications link, wherein frames with identical data that are transmitted over the first and second communications links will have an identical first SN based on the first SNS; identifying, by the MLD in the wireless network, the first SN based on the first SNS; and transmitting, by the AP MLD in the wireless network, a frame that includes the data to the non-AP MLD based on the first SN.
