1. A method implemented by a user equipment (UE) in a serving cell of the wireless communication network, the method comprising the UE:
receiving configuration information from a base station or network node for configuring discontinuous reception (DRX) by the UE;
receiving downlink control information from the base station via Layer1 signaling scheduling a data transmission, the downlink control information including an indication to the UE to:
go to sleep at the end of the scheduled transmission;
change the IAT at the end of the scheduled data transmission; or
change the power saving settings at the end of the scheduled data transmission; and
controlling or adapting DRX by the UE responsive to the downlink control information from the base station.
