Wireless Communication System, Wireless Communication Method, Wireless LAN Access Point, And Wireless LAN Station - A simplified explanation of the abstract

This abstract first appeared for US patent application 18542416 titled 'Wireless Communication System, Wireless Communication Method, Wireless LAN Access Point, And Wireless LAN Station

Simplified Explanation

The patent application describes a system for enabling simultaneous transmission from multiple stations to an access point in a wireless network.

• Station information collection unit gathers information from each station and other stations for selecting which stations can perform simultaneous transmission.
• Simultaneous-transmission request unit detects the need for simultaneous transmission based on the collected information and sends a request to the access point.
• Access point includes a station information collection unit, a simultaneous-transmission determination unit, and a trigger transmission unit to coordinate simultaneous transmission from the selected stations.

Potential Applications

This technology could be applied in:

• High-density wireless networks where multiple stations need to transmit data simultaneously.
• IoT networks with numerous devices requiring synchronized communication.

Problems Solved

This technology solves issues related to:

• Efficient utilization of network resources by enabling simultaneous transmission.
• Coordinating multiple stations to transmit data without interference.

Benefits

The benefits of this technology include:

• Improved network throughput and reduced latency.
• Enhanced reliability of data transmission in crowded network environments.

Potential Commercial Applications

Potential commercial applications for this technology include:

• Smart home systems with multiple connected devices.
• Industrial IoT networks with sensors and actuators requiring synchronized communication.

Possible Prior Art

One possible prior art for this technology could be the use of MU-MIMO (Multi-User Multiple Input Multiple Output) technology in wireless communication systems to enable simultaneous transmission from multiple users to a base station.

How does this technology handle interference between simultaneous transmissions from different stations?

The system likely employs advanced algorithms to coordinate the transmissions and mitigate interference, but the exact methods are not detailed in the abstract.

What impact does simultaneous transmission have on the overall network performance and latency?

While the technology aims to improve network throughput, the specific effects on latency and overall performance under different network conditions are not explicitly discussed in the abstract.

Original Abstract Submitted

A predetermined STA includes a station information collection unit collecting from the STA itself and other STAs station information used for selection of STAs performing simultaneous transmission and for control of the simultaneous transmission, and a simultaneous-transmission request unit knowing occurrence of a QoS data frame based on the station information and transmitting a request frame requesting the simultaneous transmission to an AP. The AP includes a station information collection unit; a simultaneous-transmission determination unit selecting a combination of the STAs performing the simultaneous transmission based on the station information by reception of the request frame; and a trigger transmission unit transmitting to each of the STAs performing the simultaneous transmission a trigger frame instructing to performs the simultaneous transmission and including information necessary for controlling the simultaneous transmission. Each of the STAs designated by the trigger frame is configured to simultaneously transmit the wireless frames to the AP.
