Abstract
In a multiple-input multiple-output (MIMO) multicarrier communication system, a mobile station sends a quantized time-domain representation of the channel transfer function to a base station for use by the base station in generating beamforming coefficients for use in subsequent transmissions to the mobile station. In some embodiments, the quantized time-domain representation of the channel transfer function may be generated from selected most significant rays of an initial estimated sampled channel impulse response. Other embodiments may be described and claimed.
