Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a modem may receive, from an applications processor of a user equipment (UE), a registration message associated with keep alive offloading. Accordingly, the modem may filter incoming transmission control protocol (TCP) packets to determine a current sequence number and a current acknowledgement number. The modem may further receive, from the applications processor, an indication to perform a keep alive procedure. Accordingly, the modem may transmit, periodically. TCP keep alive packets based on the current sequence number and the current acknowledgement number. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wired and/or wireless communication. In some aspects, a device may receive a plurality of data packets at a modem of the device. The device may group, at the modem of the device, payloads of a first subset of the plurality of data packets into a container. The device may transfer, to a processor of the device and using the modem, the container via a first interface channel. The device may transfer, to the processor and using the modem, a second subset of the plurality of data packets via a second interface channel. Numerous other aspects are provided.

Abstract: This disclosure provides a method, apparatus, and computer-readable medium for wireless communication at a modem, comprising receiving, via an interface with a host, an internet protocol (IP) packet including a first transport protocol header and a first IP header. The IP packet has a size greater than a maximum transport unit (MTU) size allowable for each packet transmitted over a communication link. The modem segments the IP packet into a plurality of segments based on a segment size indicated by a segmentation policy. Each segment includes a respective derived segment transport protocol header and a respective derived segment IP header derived from the IP packet. Each of these derived headers includes at least one field based on the segmentation policy, and each of the segment transport protocol headers includes a checksum for the respective segment. Additionally, the modem transmits the plurality of segments over the communication link.

Abstract: A UE may include one or more application processors and a modem processor. The modem processor may include flow priority engine configured to receive, from the one or more application processors, requests for determining priority treatment of one or more packet filters of one or more uplink transmissions and transmit the one or more uplink transmissions to a base station based on prioritiers of the one or more uplink transmissions. The priorities of the uplink transmissions may be determined based on at least one of the requests for priority treatment received from the one or more application processors, mapping of uplink transmissions to radio bearers, the priorities of the radio bearers, or one or more configuration rules.
