    摘要： An apparatus is disclosed having a receiver configured to receive correction information; and a transmitter configured to transmit data based on the correction information through one or more antennas to one or more nodes. A method for wireless communications is also disclosed. The method includes sending correction information to a plurality of wireless nodes; receiving corrected data generated by at least one station of the plurality of wireless nodes based on the correction information; and spatially processing the corrected data.

    摘要： Beamforming may be used in MIMO communication systems to further enhance spectral efficiency. Beamforming refers to beamed transmissions to a single destination (e.g., a station) at a time, to enhance the rate and/or range of transmission. To perform beamforming from a source to one or more destinations, a channel and/or beamforming matrices corresponding to the channel needs to be known at the source, which may be obtained as feedback from the destination. However, the beamforming matrices may not be smooth over frequency as it is fed back from the destination. Therefore, certain aspects of the present disclosure provide beamforming feedback options, resulting in the smoothness of a beamforming matrix.
