Wireless communication system, associated methods and data structures

A wireless communication device comprising:

• a beamformer to control beamforming according to capabilities information received with a feedback response from a beamformee, wherein the feedback response is selected from an immediate feedback and a delayed feedback, and the capabilities information is to be provided by a data unit which includes a beamforming capabilities field including an explicit Beam Form (BF) channel state information (CSI) feedback field to indicate whether said beamformee is capable of returning CSI explicit feedback, an explicit non compressed steering matrix feedback field to indicate whether said beamformee is capable of returning noncompressed beamforming feedback matrix explicit feedback, an explicit compressed steering matrix feedback field, and a minimal grouping field to indicate grouping of subcarriers to be used for an explicit feedback report.
