Abstract
Embodiments of the present disclosure provide a method of processing received signal using a massive MIMO base station (BS). The BS includes at least a radio unit (RU), a distributed unit (DU) and an interface. The method includes at least receiving a plurality of signals corresponding to the plurality of antennas, said signals include at least one of data signals, demodulation reference signals (DMRS) and sounding reference signals (SRS). The RU or DU performs a grouping operation on a subset of the plurality of signals corresponding to a subset of antennas to generate signal groups. The RU performs a first stage filtering on the signals associated with each group using group specific filters to obtain group specific filtered signals. The DU performs a second stage filtering on the group specific filtered signals to obtain second stage filtered signals.
