Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a transmission control protocol (TCP) packet loss based at least in part on a packet data convergence protocol (PDCP) payload of a packet. The UE may transmit a plurality of retransmission requests of the packet based at least in part on the detection of the TCP packet loss for the packet. Numerous other aspects are described.

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 wireless communication. In some aspects, a radio bearer may detect, at a packet data convergence protocol (PDCP) layer, expiry of a timer associated with a packet for transmission. The radio bearer may be configured to discard the packet upon expiry of the timer. Accordingly, the radio bearer may re-enqueue, at a modem of the radio bearer or at an application layer of the radio bearer and based at least in part on detecting expiry of the timer, the packet as a new packet for transmission before discarding the packet. Additionally, or alternatively, the radio bearer may retransmit the packet based at least in part on instructions from an application, executed on one or more processors of the radio bearer, that received the packet from the PDCP layer before the packet was discarded. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify radio access technology (RAT) state information associated with the UE, the RAT state information including an indication of whether the UE is operating in a steady state or is operating in a transition state. The UE may adapt a codec rate associated with an application of the UE based at least in part on whether the UE is operating in the steady state or is operating in the transition state. Numerous other aspects are provided.
