BEAM TRAINING TECHNIQUES IN WIFI FREQUENCY BANDS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17942006 titled 'BEAM TRAINING TECHNIQUES IN WIFI FREQUENCY BANDS

Simplified Explanation

The patent application describes methods, systems, and devices for wireless communications, specifically focusing on beam training procedures to optimize communication between wireless devices.

• A first wireless device transmits an initiating frame to a second wireless device during a service period using a transmit beam based on a beam training procedure.
• The first wireless device performs a second beam training procedure during the service period if there is no response frame from the second wireless device, based on an indication in the response frame, or if there is a change in the wireless channel.
• After the beam training procedures, the first wireless device communicates with the second wireless device using optimized beams.

Potential Applications

This technology can be applied in various wireless communication systems such as Wi-Fi networks, 5G networks, and IoT devices to improve data transmission efficiency and reliability.

Problems Solved

1. Optimizing beamforming for better wireless communication performance. 2. Addressing challenges in maintaining stable connections between wireless devices. 3. Enhancing overall network capacity and throughput.

Benefits

1. Improved data transmission speeds and reliability. 2. Enhanced network performance in crowded or dynamic environments. 3. Better utilization of wireless spectrum leading to increased efficiency.

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., station (STA), access point (AP)) may transmit to a second wireless device during a service period, an initiating frame using a transmit beam that is based on a first beam training procedure performed between the devices prior to the service period. The first wireless device may perform a second beam training procedure during the service period based on an absence of a response frame from the second wireless device, based on an indication within the response frame received from the second wireless device, or based on identification of a change in a wireless channel relative to a previous beam training interval or previous service period. The first wireless device may then communicate one or more messages with the second wireless device using one or more beams that are based on the second beam training procedure.
