Abstract
A method performed by a distributed base station system of a wireless communication network. The distributed base station system comprises a base band unit (BBU) and a remote radio unit (RRU) connected to each other over a fronthaul link. The method comprises receiving uplink signals at N antennas of the RRU from a number of user equipment (UEs) connected to the RRU. The BBU determines first beamforming weights based on a first reference signal that is has received from the UEs and sends the first beamforming weights to the RRU. The RRU then determines intermediate signals from the first beamforming weights and the uplink signals and sends the intermediate signals to the BBU. The BBU then determines second beamforming weights from a second reference signal it has received from the RRU. Then, the BBU determines an output signal based on the intermediate signal and the second beamforming weights.
