1. A network node for transmission of multi-user multiple input multiple output, MU-MIMO, signals, the network node comprising processing circuitry, the processing circuitry being configured to cause the network node to:
obtain parameter values of statistics of co-scheduled user equipment served by the network node, the statistics at least pertaining to mobility of each of the user equipment;
dynamically select a multi-user transmission configuration from candidate multi-user transmission configurations, where 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 being selected according to the parameter values and a configured mapping of the parameter values to the candidate multi-user transmission configurations; and
transmit the MU-MIMO signals towards the user equipment using the selected multi-user transmission configuration.
