Abstract: A wireless transmit/receive unit (WTRU) may receive an indication of EDT configuration information. The device may determine (e.g., based on application information, for example application layer information) that a first uplink EDT transmission is triggered for first uplink data. The application layer information may indicate an early data complete response is not required for the first uplink EDT transmission. The device may determine, based on the trigger, an EDT completion response mode to apply based on the received indication. The device may send the first uplink EDT transmission (e.g., including first uplink data) to a network to indicate that no response is expected for the first uplink EDT transmission, and a completion response mode. The device may determine that a completion indication from the network has not been detected before a time threshold. The device may, based on the lack of detection, continue operation in accordance with an idle condition and monitor for a paging message.
