Techniques for low-latency, low-loss, scalable throughput capability at user equipment

A method for wireless communications by a user equipment (UE), comprising:

• receiving, at a first modem of the UE and from a first device, one or more data packets;
• routing the one or more data packets from the first modem to two or more queues associated with a second modem of the UE based at least in part on an explicit congestion notification (ECN)-capable transport (ECT) codepoint indication in respective header portions of the one or more data packets;
• receiving buffer and link state information associated with the second modem;
• performing, based at least in part on the buffer and link state information, a congestion indication procedure, wherein the congestion indication procedure is associated with congestion of a communication link for the UE;
• and
• transmitting, to a second device and based at least in part on a respective priority associated with the two or more queues, packet data from the two or more queues associated with the second modem of the UE.

A non-transitory computer-readable medium storing code for wireless communications, the code comprising instructions executable by one or more processors of a user equipment (UE) to:

• receive, at a first modem of the UE and from a first device, one or more data packets;
• route the one or more data packets from the first modem to two or more queues associated with a second modem of the UE based at least in part on an explicit congestion notification (ECN)-capable transport (ECT) codepoint indication in respective header portions of the one or more data packets;
• receive buffer and link state information associated with the second modem;
• perform, based at least in part on the buffer and link state information, a congestion indication procedure, wherein the congestion indication procedure is associated with congestion of a communication link for the UE;
• and
• transmit, to a second device and based at least in part on a respective priority associated with the two or more queues, packet data from the two or more queues associated with the second modem of the UE.
