Host driven modem uplink packet prioritization

A method for wireless communication at a host processor of a user equipment (UE), comprising:

• identifying, for each of a plurality of packets to be transmitted by the UE, a priority value that indicates one of two or more priority levels, the priority value of each packet for use in ordering packet transmissions at a wireless modem of the UE, wherein the host processor interacts with one or more applications at an application layer of the UE to provide the plurality of packets to be transmitted by the UE;
• formatting, for each of the plurality of packets, a multiplexing and aggregation header that includes a priority field that indicates the priority value of the corresponding packet, wherein the plurality of packets are ordered based at least in part on the priority field and an evaluation of tuple information, and wherein the tuple information comprises a source address, a destination address, a source port number, a destination port number, a protocol, or any combinations thereof;
• and
• providing the multiplexing and aggregation headers and the plurality of packets to a layered protocol stack at the wireless modem for ordering and transmission to an access network entity.

An apparatus for wireless communication, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, at a wireless modem of a user equipment (UE), a plurality of multiplexing and aggregation headers from a host processor of the UE that interacts with one or more applications at an application layer of the UE to provide a plurality of packets to be transmitted by the UE, each multiplexing and aggregation header of the plurality of multiplexing and aggregation headers associated with at least one corresponding packet of the plurality of packets to be transmitted by the UE;
• order, at one or more layers of a layered protocol stack at the wireless modem of the UE, the plurality of packets to generate an ordered plurality of packets, the ordering based at least in part on a priority value of each packet that is provided by the host processor to the layered protocol stack and is indicated in a priority field of the corresponding multiplexing and aggregation header;
• identify a set of packets of the ordered plurality of packets having a first priority level of a plurality of available priority levels;
• evaluate tuple information for each packet of the set of packets to determine a first subset of packets within the first priority level that are to be transmitted ahead of a second subset of packets within the first priority level wherein the tuple information comprises a source address, a destination address, a source port number, a destination port number, a protocol, or any combinations thereof;
• order the first subset of packets ahead of the second subset of packets based at least in part on the evaluating;
• and
• transmit the ordered plurality of packets comprising the ordered first subset of packets and the ordered second subset of packets to an access network entity.
