Methods for transmitting and receiving data in 5G NR device based on data/service tagging from application processor

A user equipment device (UE), comprising:

• an antenna;
• a radio operably coupled to the antenna;
• and
• a processor operably coupled to the radio;
• wherein the antenna, radio, and processor are configured to:
• establish a first connection for a data flow, wherein the first connection utilizes a first 3rd Generation Partnership Project (3GPP) air interface;
• establish a second connection for the data flow, wherein the second connection utilizes a second 3GPP air interface;
• and
• determine 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;
• transmit, 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.

A computer-readable non-transitory memory medium comprising program instructions that, when executed by a processor of a user equipment device (UE), cause the UE to:

• initiate redundancy for a data flow, wherein in initiating the redundancy the program instructions are executable to cause the UE to:
• establish a first subflow in a first connection for the data flow, wherein the first connection utilizes a first 3rd Generation Partnership Project (3GPP) air interface;
• establish a second subflow in a second connection for the data flow, wherein the second connection utilizes a second 3GPP air interface;
• determine whether to transmit the data flow using the 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, and wherein the duplication of data packets is performed above a packet data convergence protocol (PDCP) layer;
• and
• transmit, 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.
