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: Some aspects of the present disclosure disclose methods and systems for managing transmission control protocol (TCP) acknowledgements (ACK) transmissions from a host or application processor to a modem of a user equipment. The UE may detect availability of buffer space in a memory buffer of a modem of the UE. Further, the UE may also detect that a host processor of the UE lacks credit sufficient for transmitting data from the host processor to the modem. The UE may then generate and transmit to the host processor a data flow control (DFC) command including credit sufficient for the host processor to transmit at least a portion of the data to the modem. In some instances, in response to the transmission of the DFC command, the at least the portion of the data may be received at the modem from the host processor.

Abstract: A user equipment (UE) may be configured with one or more queues at which packets are accumulated before being transferred between at least one higher layer and at least one lower layer. The UE may release packets from the one or more queues based on at least one set of parameters. The UE may determine one or more radio conditions associated with at least one traffic flow between the UE and a network. The UE may configure a set of parameters associated with transfer of packets for the at least one traffic flow between a lower layer of the UE and a higher layer of the UE based on the one or more radio conditions. The UE may communicate a first set of packets with the network for the at least one traffic flow based on the set of parameters.

Abstract: In a wireless network, a user equipment (UE) may support reflective quality of service (QoS), where QoS applied to uplink packets is implicitly derived from downlink packets. For example, when the UE receives a downlink packet that includes a reflective QoS (RQoS) indicator and a QoS flow identifier (QFI), the UE may apply the same QoS associated with the downlink packet to an uplink packet with one or more attributes that match the downlink packet. However, for a received downlink encapsulating security payload (ESP) packet that includes an RQoS indicator and a QFI, a modem cannot determine an uplink security parameters index (SPI) and downlink SPI pairing needed to enable RQoS because the uplink/downlink SPI pairing is known only by the upper layer. Accordingly, some aspects described herein enable the modem to learn uplink/downlink SPI pairings for ESP packets and thereby enable RQoS for ESP packets.

Abstract: Certain aspects of the present disclosure provide techniques for implementing reflective quality of service (RQoS) in wireless communication systems. A method for implementing RQoS that may be performed by a user equipment (UE) generally includes receiving a plurality of downlink user data packets from a first base station (BS), determining at least one reflective quality of service (RQoS) mapping rule for one or more uplink packet transmissions based on a subset of the plurality of downlink user data packets, filtering the plurality of downlink user data packets based on the at least one RQoS mapping rule, and forwarding the plurality of downlink user data packets to a corresponding application entity of the UE based on the filtering.

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: Certain aspects of the present disclosure provide techniques for avoiding out of order uplink data reception upon data radio bearer (DRB) release or quality of service (QoS) flow addition. An exemplary method that may be performed by a user equipment (UE), includes obtaining an indication that a first data radio bearer (DRB) is released or handed over to a second DRB, wherein a first mapping maps a first quality of service (QoS) flow to the first DRB; obtaining a second mapping that maps the first QoS flow to a second DRB; editing service data adaptation protocol (SDAP) headers of uplink protocol data units (PDUs) in an uplink transmission buffer associated with the first DRB, based on a difference between a first configuration of the first DRB and a second configuration of the second DRB; and transmitting the uplink PDUs via the second DRB.

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.
