The disclosure relates to a method, performed in a multi-antenna radio access node comprising four logical antenna ports mapped to corresponding physical antennas, of transmitting data using three physical antennas. The method comprises determining (S51) loss of data transmission from one physical antenna of the four physical antennas. A required multi-antenna transmission scheme is determined (S52). An antenna mapping matrix prestored in the radio access node is selected (S53), the selected antenna mapping matrix adapted to the required multi-antenna transmission scheme. Data on the four logical antenna ports are re-mapped (S54) to the remaining three physical antennas by using the selected antenna mapping matrix, whereupon the data is transmitted (S55) from the remaining three physical antennas.
A method, performed in a multi-antenna radio access node comprising four logical antenna ports mapped to corresponding physical antennas, of transmitting data using three physical antennas, the method comprising:
A multi-antenna radio access node in a wireless network, the radio access node configured for enabling downlink data transmission over a reduced number of physical antennas, the radio access node comprising:
A computer program product stored in a non-transitory computer readable medium for controlling a multi-antenna radio access node comprising four logical antenna ports mapped to corresponding physical antennas so as to transmit data using three physical antennas, the computer program product comprising software instructions which, when run on a processor of the access node, causes the access node to:
