Various embodiments provide methods for Internet Protocol (IP) packet handling. Various embodiments may enable downlink (DL) data prioritization of IP packets for time-sensitive applications, for example by using differentiated services code point (DSCP) indications or type-of-service (TOS) indications in headers of the IP packets to distinguish prioritized IP packets from non-prioritized IP packets. In various embodiments, IP packets that are prioritized IP packets may be sent to another processor of a wireless device using a prioritized traffic handling configuration that has a lower latency than a default traffic handling configuration used for sending non-prioritized IP packets. Various embodiments may further enable uplink (UL) data prioritization of IP packets.
