Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract: Aspects of the present disclosure describe transmitting data in wireless communications. A set of packets for transmission in a defined sequence can be received where the set of packets includes two or more packets. It can be detected that a packet, of the set of packets, is a prioritized packet type. The packet can be prioritized for transmission ahead of its order in the defined sequence based on the detection of the prioritized packet type. The packet can be transmitted ahead of its order in the defined sequence to an access point.

Abstract: Methods, systems, and devices for wireless communications are described. In aspects, a wireless device such as a user equipment (UE) may identify an amount of acknowledgement (ACK) reduction associated with an applications processor. The amount of ACK reduction may be determined based on a communication from the applications processor, or an ACK frequency in a group of packets received from the applications processor. The UE may determine whether to modify an ACK management scheme (e.g., a transmission control protocol (TCP) ACK coalescing scheme) based at least in part on the amount of ACK reduction associated with the applications processor. The UE may modify the ACK management scheme. The UE may transmit ACKs in accordance with the modified ACK management scheme. Numerous other aspects are provided.

Further, the apparatus may compress the second header of each of the second set of packets using a second CID associated with the connection. The apparatus may send the first set of packets through the connection. The apparatus may send, after sending the first set of packets, the second set of packets through the connection.
