Claim 37:
38. A method of processing, the method comprising:
processing, via a base station (BS), by:
receiving a plurality of signals corresponding to a plurality of antennas, wherein the plurality of signals comprise data signals, demodulation reference signals (DM RS) and sounding reference signals (SRS);
grouping subsets of the plurality of signals to generate a plurality of signal groups; and
filtering each of the plurality of signal groups using one or more group specific filters to obtain one or more group specific filtered signals, wherein a group specific filter for a particular signal group is determined according to signals associated with the particular signal group and/or the SRS, wherein:
the group specific filter for the particular signal group is determined according to predetermined values obtained using one or more group specific Discrete Fourier Transform (DFT) weights, and
the group specific DFT weights include a group specific steering angle.
