ABSTRACT:
The invention relates to a method, a base station and a computer program for selecting a spatial transmission method for a next downlink transmission in a base station. The base station can be a WiMAX, a UMTS or a 3 GPP LTE base station. According to the invention the base station makes a selection between beamforming (BF), space-time coding (STC) or MIMO for a next downlink frame. The selection is based on uplink measurements and feedback information from a particular mobile station whereto the next downlink frame is to be transmitted.
