Method and apparatuses for low-latency transmission of sensor data and wireless modem data are described herein. A method may comprise associating, by a Wireless Transmit/Receive Unit (WTRU), a first Unique Data Identifier (UDI) with the sensor data and a second UDI with the wireless modem data. The method may further comprise generating, by the WTRU, a mapping between the first UDI and a first network Quality of Service (QoS) Flow Identifiers (QFIs) and a mapping between the second UDI and a second network QFI. The method may further comprise transmitting, by the WTRU, the sensor data and the wireless modem data to a network node.
