Techniques for tunneling for a multi-subscription user equipment

A method of wireless communication performed by a user equipment (UE), comprising:

• communicating using a first radio access technology (RAT) for a first subscription of the UE, wherein the first RAT is selected from a group that includes a first cellular RAT associated with the first subscription, a second cellular RAT associated with a second subscription of the UE, and a wireless local area network (WLAN) RAT;
• communicating using a second RAT for the second subscription of the UE, wherein the second RAT is selected from the group that includes the first cellular RAT associated with the first subscription, the second cellular RAT associated with the second subscription of the UE, and the WLAN RAT;
• and
• transitioning, based at least in part on a condition associated with a user activity of the UE or a condition associated with a device configuration of the UE, a communication link carrying a protocol data unit (PDU) session from the second subscription to the first subscription.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• communicate using a first radio access technology (RAT) for a first subscription of the UE, wherein the first RAT is a cellular RAT associated with the first subscription, where the UE is associated with a second subscription that can communicate using a communication link carrying a protocol data unit (PDU) session on the first RAT of the first subscription;
• and
• establish, with a gateway, the communication link carrying the PDU session on the first RAT of the first subscription.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• communicate using a first radio access technology (RAT) for a first subscription of the UE, wherein the first RAT is selected from a group that includes a first cellular RAT associated with the first subscription, a second cellular RAT associated with a second subscription of the UE, and a wireless local area network (WLAN) RAT;
• communicate using a second RAT for the second subscription of the UE, wherein the second RAT is selected from the group that includes the first cellular RAT associated with the first subscription, the second cellular RAT associated with the second subscription of the UE, and the WLAN RAT;
• and
• transition, based at least in part on a condition associated with a user activity of the UE or a condition associated with a device configuration of the UE, a communication link carrying a protocol data unit (PDU) session from the second subscription to the first subscription.
