Abstract: Wireless communications systems and methods related to uplink buffer management are provided. In some aspects, a user equipment receives a synchronization acknowledgment message destined for a device tethered to the user equipment and transmitted by an application server at a network to which the user equipment is connected. In some aspects, the synchronization acknowledgment message includes an application server receiver window size indicating available buffer space in a receive buffer of the application server. The user equipment can modify the application server receiver window size in the received synchronization acknowledgment message prior to transmitting the received synchronization acknowledgment to the tethered device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. For example, when a modem of a user equipment (UE) receives a burst of reset (RST) packets from an application processor, the modem may send only one RST packet and prune the remaining RST packets in the RST packet burst, or may send only one RST packet in a time period in cases where the RST packet burst is associated with a closed TCP connection and/or a TCP connection for which an RST packet has already been sent to a network node. Additionally or alternatively, the modem may inform the application processor to prune RST packets associated with the closed TCP connections and/or the TCP connections for which an RST packet has already been sent. Furthermore, similar techniques may be applied at the network node to avoid sending downlink traffic that is likely to result in uplink RST traffic.

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: 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.

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: Methods executed by a processor element for providing data packets from a modem to an application processor in a computing device are disclosed. Exemplary implementations may reorder packets received by the modem from a plurality of parallel flows so as to provide to the application processor batches of packets from individual flows within the plurality of parallel flows.
