1. A method for operating a user equipment device (UE), comprising:
establishing a first connection for a data flow, wherein the first connection utilizes a first 3rd Generation Partnership Project (3GPP) air interface;
establishing a second connection for the data flow, wherein the second connection utilizes a second 3GPP air interface;
determining whether to transmit the data flow using redundancy, wherein determining whether to transmit the data flow using redundancy is performed based on a number of active links per radio bearer and on a round trip time (RTT), wherein it is determined to not use redundancy to transmit the data flow when the RTT is greater than a threshold, wherein the redundancy comprises duplicating data packets using a multipath transmission control protocol (MPTCP) with two internet protocol (IP) interfaces, and wherein the duplication of data packets is performed above a packet data convergence protocol (PDCP) layer;
transmitting, based on the determination whether to transmit the data flow using redundancy, the data flow over at least one of the first connection and the second connection.
