Abstract
A network device may be configured to adapt beamforming parameters for a communication region of a powerline cycle in response to variations in communication channel conditions. A first network device can estimate initial beamforming parameters for each communication region based on sounding messages received from a second network device. The first network device can determine coarse beamforming parameters for each communication region based on data packets received from the second network device using the initial beamforming parameters. The first network device can determine a difference parameter for the first communication region based, at least in part, on a first initial beamforming parameter associated with the first communication region and a first coarse beamforming parameter associated with the first communication region. The first network device can compare the difference parameter with a difference threshold to determine whether to estimate a first modified beamforming parameter for a first communication region.
