Beamforming precoding matrix using non-uniform angles quantization. Adaptively generated feedback information is provided between communication devices that communicate using more than one communication path, link, connection, etc. With respect to feeding back different types of information having different respective characteristics (e.g., different respective probability density functions), different and respective quantization may be employed for the different types of information. For example, uniform, Gaussian, or per bit loop optimized quantization may be individually selected and employed for each of the different types of feedback information used in a wired communication system (e.g., one which is implemented or compliant in accordance with PLC/HP (Powerline/HomePlug), and/or at least one version of the IEEE 1901-2010—IEEE Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications), signaling may be effectuated between communication devices using more than one communication pathway (e.g., more than one communication link between respective communication devices).
