SYNCHRONIZED CHANNEL ACCESS COEXISTENCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18064833 titled 'SYNCHRONIZED CHANNEL ACCESS COEXISTENCE

Abstract

This patent application describes methods, devices, and systems for synchronized channel access in wireless communication devices. It focuses on facilitating coexistence between devices that support synchronized channel access and those that do not. The implementation involves a group of access points scheduling recurring quiet periods using quiet elements, during which legacy devices are not allowed to transmit. Additionally, an access point may transmit quiet override elements to indicate to other access points that they can contend for access during the quiet period. If an access point wins contention for multiple consecutive synchronized channel access periods, it may be entitled to an extended TXOP.

Explanation

• The patent application introduces methods, devices, and systems for synchronized channel access in wireless communication devices.
• It addresses the challenge of coexistence between devices that support synchronized channel access and those that do not.
• Access points in a group can schedule recurring quiet periods using quiet elements, preventing legacy devices from transmitting during these periods.
• An access point can transmit quiet override elements to allow other access points supporting synchronized channel access to contend for access during the quiet period.
• If an access point wins contention for multiple consecutive synchronized channel access periods, it may receive an extended TXOP (transmission opportunity).

Potential Applications

This technology has potential applications in various fields, including:

• Wireless communication networks
• Internet of Things (IoT) devices
• Smart home systems
• Industrial automation
• Public Wi-Fi networks

Problems Solved

The synchronized channel access technology solves several problems, such as:

• Coexistence between devices that support synchronized channel access and those that do not, ensuring fair access to the channel.
• Efficient utilization of the wireless channel by scheduling recurring quiet periods.
• Providing extended transmission opportunities to access points that consistently win contention, improving overall network performance.

Benefits

The benefits of this technology include:

• Improved coexistence among wireless communication devices with different channel access capabilities.
• Enhanced efficiency in channel utilization by establishing recurring quiet periods.
• Fair access to the channel for all devices, ensuring equal opportunities for transmission.
• Extended transmission opportunities for access points that consistently win contention, leading to improved network performance.

Original Abstract Submitted

This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period. In some other implementations of synchronized channel access, an access point supporting synchronized channel access that wins contention after one or more consecutive synchronized channel access periods during which no other synchronized access points won contention, may be entitled to an extended TXOP.
