Dual connectivity for reliability

A non-transitory computer-readable storage medium storing program instructions executable by one or more processors of a user equipment (UE) to configure the UE to perform operations to:

• identify a data session to be duplicated based at least in part on an importance level of the data session;
• wherein a connection structure for the data session to be duplicated includes duplication of the data session above access stratum (AS) layers;
• wherein the AS layers include at least PDCP and PHY layers;
• initiate transmission of data associated with the data session using a first transmission mode to a first transmission point, wherein the first transmission mode uses a first radio access technology (RAT);
• and
• initiate transmission of the data associated with the data session using a second transmission mode to a second transmission point, wherein the second transmission mode uses a second RAT, wherein the second RAT is different than the first RAT;
• wherein the first RAT to the first transmission point and the second RAT to the second transmission point establish dual connectivity in which the UE is configured for use of a primary radio link and a secondary radio link for transmission.

A wireless device, comprising:

• wireless communication circuitry;
• and
• at least one processor coupled to the wireless communication circuitry and configured to cause the wireless device to:
• identify a data session to be duplicated based at least in part on an importance level of the data session;
• wherein a connection structure for the data session to be duplicated includes duplication of the data session above access stratum (AS) layers;
• wherein the AS layers include at least packet data convergence protocol (PDCP) and physical (PHY) layers;
• initiate transmission of data associated with the data session using a first transmission mode to a first transmission point, wherein the first transmission mode uses a first radio access technology (RAT);
• and
• initiate transmission of the data associated with the data session using a second transmission mode to a second transmission point, wherein the second transmission mode uses a second RAT, wherein the second RAT is different than the first RAT;
• wherein the first RAT to the first transmission point and the second RAT to the second transmission point establish dual connectivity in which the UE is configured for use of a primary radio link and a secondary radio link for transmission.
