Abstract: This invention introduces methods and mechanisms of partial integrity protection in mobile systems. A device comprising: a memory configured to store instructions; and a processor configured to execute the instructions to: generate a representation value based on protocol data unit (PDU) header data and payload data of a PDU; generate a message authentication code based on the representation value; and include the message authentication code in the PDU.

Abstract: This invention introduces methods and mechanisms of partial integrity protection in mobile systems. A user equipment (UE), comprising: a memory configured to store instructions; and a processor configured to execute the instructions to: receive, from a network device, user plane data having integrity protection; send an error indication indicating an integrity protection error relating to the user plane data; and receive retransmitted user plane data from the network device with a reduced data rate, based on the error indication.
