1. A network node, comprising processing circuitry configured to:
cause transmission of a Discontinuous Reception, DRX, configuration to a wireless device using communication layer 3 signaling;
cause transmission of an indication to the wireless device to trigger activation at one of communication layer 1 and communication layer 2 of the DRX configuration; and
determine whether the wireless device has activated the DRX configuration based on whether a hybrid automatic repeat request acknowledgement, HARQ ACK, is received in response to transmission of the indication.
