Abstract

A methodis performed by a baseband unit (BBU)for scaling beamforming weights (BFWs) to assist a Radio Unit (RU)with beamforming. The method includes obtaininga plurality of frequency-domain BFWs for beamforming of a number of downlink data streams in frequency-domain to be transmitted to at least one wireless device via a plurality of antennas. The BBU scalesthe plurality of frequency-domain BFWs based on at least one scaling factor and compressesthe plurality of scaled frequency-domain BFWs. The BBU transmits, to the RU, the scaled frequency-domain BFWs that have been compressed. The BBU also determinesat least one user plane scaling factor for frequency-domain user plane IQ data, scalesthe frequency-domain user plane IQ data based on the user plane scaling factors, and transmitsthe scaled frequency-domain user plane IQ data to the RU.
