Abstract
The disclosure relates to a method performed in a network node for transmitting data in a wireless network. The network node is configurable for controlling a multiple input multiple output antenna system. The method comprises beamforming user specific data streams to one or more communication devices, UE1, . . . , UEK, wherein the beamforming is based on respective channel information available for each of the one or more communication devices, UE1, . . . , UEK, precoding control information streams using a transmit diversity scheme; and transmitting the beamformed user specific data streams and the precoded control information streams in a same transmission resource. The disclosure relates to a network node, method in communication device, communication device and computer programs and computer program products.
