Abstract: A notification regarding a transition of a User Equipment (UE) from a standby operating mode to an active operating mode is exchanged between a UE and a network element in a communication network. The notification could be an uplink notification that is transmitted by the UE to the network element in response to an operating mode transition criterion for the UE being met at the UE, or a downlink notification that is transmitted by the network element to the UE in response to an operating mode transition criterion for the UE being met at the network element. The UE transitions from the standby operating mode to the active operating mode in response to the operating mode transition criterion being satisfied. The transmitter of the notification, which could be the UE or the network element, could also perform grant-free transmission of data without first receiving a response to the notification.
