Zusammenfassung:	Integrity protection is used to assist in ensuring the secure transmission of wireless data within a cellular network. Instead of performing integrity protection on each packet data unit (PDU) transmitted/received within a PDU session, integrity protection is performed on a portion of PDUs transmitted within a cellular network. For instance, partial integrity protection may be performed on at least one predetermined PDU (e.g., the first, second, fourth, . . . ) that is transmitted via a Physical Downlink Shared Channel (PDSCH)/Physical Uplink Shared Channel (PUSCH) during a communication session. By performing partial integrity protection, user data may be transmitted more quickly throughout the cellular network, compared to performing full integrity protection, while still providing integrity protection.
