Abstract: Embodiments of a Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with logical nodes including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU 106 may determine a first precoding matrix and a second precoding matrix for a precoding of one or more data streams for transmission on a plurality of antennas coupled to the gNB-DU. The precoding may be in accordance with a split functionality between the gNB-CU and the gNB-DU that includes: precoding by the gNB-CU with the first precoding matrix, and precoding by the gNB-DU with the second precoding matrix.

Abstract: A method of processing signals in a radio processing apparatus of a base station may include obtaining a plurality of aggregated data symbols, wherein each of the plurality of aggregated data symbols corresponds to a receive terminal of a plurality of receive terminals of the base station and is composed of transmitted data symbols from a plurality of transmit terminals; applying a compression filter to the plurality of aggregated data symbols to reduce the plurality of aggregated data symbols into a plurality of isolated data symbols, the compression filter being based on channel estimates between the plurality of receive terminals and the plurality of transmit terminals; and transmitting the plurality of isolated data symbols to a baseband processing apparatus of the base station.
