ACCESS TO RANDOM RESOURCE UNITS BY A PLURALITY OF BSSs - A simplified explanation of the abstract

This abstract first appeared for US patent application 18482771 titled 'ACCESS TO RANDOM RESOURCE UNITS BY A PLURALITY OF BSSs

Simplified Explanation

The abstract describes a patent application for a physical access point (AP) that manages multiple base station systems (BSSs) through virtual access points (VAPs). The AP sends a trigger frame to reserve a transmission opportunity (TXOP) and allocates resource units for nodes to transmit data during the reserved TXOP. The trigger frame identifies multiple groups of nodes that are allowed to access the resource units during the TXOP. This allows the AP to receive data from different nodes in different groups during the reserved TXOP, reducing the need for multiple access attempts and minimizing channel occupation by control frames.

  • The patent application proposes a method for a physical AP to manage multiple BSSs through VAPs.
  • The AP sends a trigger frame to reserve a TXOP and allocate resource units for data transmission.
  • The trigger frame identifies multiple groups of nodes allowed to access the resource units during the TXOP.
  • The AP can receive data from different nodes in different groups during the reserved TXOP.
  • This reduces the need for multiple access attempts and minimizes channel occupation by control frames.
  • The number of trigger frames can be significantly reduced while offering resource units to several BSSs.

Potential Applications:

  • Wireless communication networks
  • Internet of Things (IoT) systems
  • Wi-Fi access points and routers

Problems Solved:

  • Channel congestion due to control frames
  • Inefficient utilization of channel resources
  • Complex management of multiple BSSs

Benefits:

  • Improved channel utilization
  • Reduced channel occupation by control frames
  • Simplified management of multiple BSSs
  • Increased efficiency in data transmission


Original Abstract Submitted

A physical AP manages a plurality of BSSs through VAPs. The AP sends a trigger frame to reserve a TXOP including resource units the nodes access to transmit data during the reserved TXOP. To improve channel utilization, the trigger frame identifies a plurality of groups, nodes of which are allowed to access the resources units to transmit data during the reserved TXOP. Thus, the AP receives, during the reserved TXOP, data from one node of a first group identified in the trigger frame and data from one node (separate from the first one) of a second and separate group identified in the trigger frame. A single access by the AP to the medium is thus required, reducing the channel occupation due to control frames. In some embodiments, the number of trigger frames can be drastically reduce, while offering resource units to several BSSs.
