There is provided mechanisms for transmission of MU-MIMO signals. A method is performed by a network node. The method includes obtaining parameter values of statistics of co-scheduled user equipment served by the network node. The statistics at least pertains to mobility of each of the user equipment. The method includes dynamically selecting a multi-user transmission configuration from candidate multi-user transmission configurations. Each candidate multi-user transmission configuration specifies at least a digital precoding mode selected from candidate digital precoding modes and an analog beam steering mode selected from candidate analog beam steering modes. The multi-user transmission configuration is selected according to the parameter values and a configured mapping of the parameter values to the candidate multi-user transmission configurations. The method includes transmitting the MU-MIMO signals towards the user equipment using the selected multi-user transmission configuration.
