Abstract

Methods, apparatus and systems for motion-predictive beamforming are disclosed. A method for motion predictive beamforming includes determining a time of a predicted transmission and determining a future position of a virtual reality (VR) receiving device at the time of the predicted transmission. Beamforming parameters are forwarded wireless system that correspond to the future position of the VR receiving device, the time of the predicted transmission, and an error correction margin to cause a transmission of a beam that is formed based on the future position of the VR receiving device, the time of the predicted transmission, and the error correction margin.

Background

Beamforming technology enables the energy of a wireless transmitter to be focused in one or more specific directions to ensure a better quality of transmission in those directions. A direction in which the transmitter is focused can be programmatically changed to accommodate changes in user conditions such as movement of the receiving device. In such systems, the transmitter direction changes are based on the instructions that are provided by a programmer. The drawback of this approach is that dynamically moving receiving devices have a high likelihood of moving outside of the range specified by the programmer. Thus, the benefit of focusing the energy of the wireless transmitter in a specified direction/range is negated.
