1. A cellular base station, comprising:
an antenna;
a radio coupled to the antenna; and
a processor coupled to the radio and configured to cause the cellular base station to:
establish a radio resource control (RRC) connection with a wireless device according to a first radio access technology (RAT);
transmit a first downlink control information (DCI) message scheduling a first physical downlink shared channel (PDSCH) transmission to the wireless device, wherein a time gap between the first DCI message and the first PDSCH transmission is given by a first K0, wherein the first K0 is indicated in the first DCI message and selected from a first set of possible K0 values that includes K0=0;
configure the wireless device with a K0 minimum value (K0_min) to be greater than zero to enable power savings at the wireless device; and
transmit, after the configuration of the wireless device with K0_min, a second DCI message for scheduling a second PDSCH transmission to the wireless device, wherein the second DCI message includes a second K0 for scheduling the second PDSCH transmission, the second K0 selected from a second set of possible K0 values that does not include K0=0.
