Abstract
Method performed by a first communication device () for adapting a pre-coder used by a second communication device () to transmit radio signals using beamforming to a third communication device (). The first communication device (), the second communication device (), and the third communication device () operate in a wireless communications network (). The first communication device () adapts (), over a single time period of transmission of the radio signals, the pre-coder used by the second communication device () to transmit the radio signals to the third communication device () using beamforming. The adapting () is based on a change, over the single time period, in a state of a channel used to transmit the radio signals. The state is measured by the second communication device ().
