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.

Facilitating quality of service flow remapping utilizing a service data adaptation protocol layer

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.

Techniques for improving reflective quality of service

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.

Transmission control protocol (TCP) and/or user datagram protocol (UDP) receive offloading

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.

Prioritizing packets in wireless communications

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.

A method for reordering data by an electronic device is described, including receiving a first set of data packets via a first radio access technology (RAT). The method also includes receiving a second set of data packets via a second RAT. The first and second sets of data packets are from a data stream. The method further includes providing at least a portion of the first set of data packets or of the second set of data packets to an application processor. The method additionally includes buffering, in application processor memory, the at least the portion of the first set of data packets or the at least the portion of the second set of data packets. The method also includes reordering the at least the portion of the first set of data packets or the at least the portion of the second set of data packets.

When sending a first set of packets is determined to be prioritized over sending a second set of packets, and when each first header of each of the first set of packets and each second header of each of the second set of packets is determined to be compressed, an apparatus may compress the first header of each of the first set of packets using a first CID associated with a connection. 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.

Techniques are described for wireless communication at a wireless communication device. One method includes receiving wireless wide area network (WWAN) packets at a WWAN processing subsystem of the wireless communication device; transferring wireless local area network (WLAN) packet information from a WLAN processing subsystem of the wireless communication device to the WWAN processing subsystem, the WLAN packet information comprising a subset of data associated with WLAN packets; performing a reordering process in the WWAN processing subsystem, the reordering process based at least in part on the received WWAN packets and the WLAN packets that correspond to the transferred WLAN packet information; and providing an indication of the reordered WWAN packets and the WLAN packets to an application processing subsystem of the wireless communication device.

A method, an apparatus, and a computer program product for transport protocol communications processing are provided. The apparatus may be an electronic device. The electronic device receives a transport protocol communications from a sender device. The electronic device generates a plurality of acknowledgments in response to the received transport protocol traffic and stores the plurality of acknowledgments at a first memory. A modem load for a modem of the electronic device is determined. The electronic device identifies the plurality of acknowledgments to identify a subset of the plurality of acknowledgments in response to the determined modem load satisfying a modem load threshold condition. The electronic device moves the subset of acknowledgments from the first memory to a second memory. The electronic device transmits the subset of acknowledgments to the sender device.

Transport protocol communications reduction

Techniques for routing data via lower layer paths through lower layers of a protocol stack are described. A lower layer path may be composed of a flow for packets, a link at a link layer, and a channel at a physical layer. A packet may be received from an application. A most preferred lower layer path for the packet may be selected from among at least one available lower layer path. The available lower layer path(s) may be arranged in an order of preference based on treatment of packets (e.g., best effort or QoS), protocols used at the link layer, channel types at the physical layer, and/or other factors. The packet may be sent via the selected lower layer path. A highest precedence lower layer path for the packet may be set up (e.g., in parallel) if this path is not among the at least one available lower layer path.

Data routing via lower layers in a communication system

Techniques for modifying packet filters in a wireless communication network are described. In one scheme, packet filters may be performed with multiple operations, if needed. The operation(s) to be performed and the order of performing the operation(s) may be dependent on the number of existing packet filters to be replaced (N) and the number of new packet filters (M). If N=M, then N packet filters in a traffic filter template may be replaced with a single operation. If N&#x3e;M, then M packet filters in the traffic filter template may be replaced first, and N&#x2212;M packet filters may be deleted from the traffic filter template next. If N&#x3c;M, then M&#x2212;N new packet filters may be added to the traffic filter template first, and N packet filters in the traffic filter template may be replaced next. In another scheme, packet filters are modified with a single operation using dummy packet filters, if needed.

Efficient modification of packet filters in a wireless communication network

In a method for managing quality of service (QoS) resources during handoff across communication systems having different grades of QoS awareness, an access terminal (AT) determines that handoff has occurred from a QoS unaware system to a QoS aware system. The AT also determines whether there are any allocated, unrequested QoS resources. If one or more allocated, unrequested QoS resources are identified, the AT requests that the QoS aware system release the one or more allocated, unrequested QoS resources. The AT also determines whether there are any requested, unallocated QoS resources. If one or more requested, unallocated QoS resources are identified, the AT requests that the QoS aware system allocate the one or more requested, unallocated QoS resources to the application.
