wherein the one or more grant-free transmissions are performed after the transmitting the request message requesting to the transition to the active operating mode, or
wherein the one or more grant-free transmissions include the request message and a subsequent grant-free transmission;
receiving, by the apparatus from the network element, downlink data before receiving the response from the network element;
receiving, by the apparatus that is in the first operating mode from the network element, the response approving the transition; and
