Sony patents method for devices to request specific Wi-Fi feedback formats

Patent drawing
Patent drawing from the official filing.

Sony describes a system where a main communication device asks other devices in its network for specific types of feedback data. The main device sends training signals and requests a set number of feedback vectors, then uses this returned information to calculate a steering matrix for better signal direction.

Why it mattersThis filing focuses on refining how devices in a wireless network exchange data to improve beamforming, which can lead to more stable and efficient connections in crowded environments.

In the filing’s own words

A first communication device configured to communicate with one or more third communication devices in its basic service set comprises circuitry configured to transmit fourth feedback request information to the fourth communication device, the fourth feedback request information relating to feedback to be fed back by the fourth communication device and including a requested feedback format and a requested number or number range of feedback vectors; transmit fourth training data to at least the fourth communication device; receive fourth beamforming feedback from the fourth communication device, the fourth beamforming feedback including a number of feedback vectors according to the requested feedback format; determine, based on the received fourth beamforming feedback, a steering matrix for communicating with the one or more third communication devices using beamforming; and communicate with the one or more third communication devices using the determined steering matrix.
