Abstract: This disclosure describes methods, systems, and devices for uplink data integrity protection in a communication system including a radio access network (RAN) serving a user equipment (UE) operating in an Early Data Transmission (EDT) configuration. In one example, a method involves generating a hash marker based on a packet data convergence protocol (PDCP) control protocol data unit (PDU) or service data unit (SDU). The method also involves transmitting a message including the hash marker to the RAN.
