    Abstract: A client device in a wireless network accesses a queue comprising Transmission Control Protocol Acknowledgement (TCP ACK) packets. At least some packets include packet descriptors with a flow identifier indicating a corresponding TCP flow, and a TCP ACK Generation Count. The device inspects a packet descriptor of a first TCP ACK packet, and identifies a first flow identifier and a first TCP ACK Generation Count. The device accesses entries in a data structure that each includes a first field and a second field respectively storing a flow identifier and a TCP ACK Generation Count. The device determines that a condition is satisfied, comprising that an entry in the data structure includes a flow identifier and a TCP ACK Generation Count matching the first flow identifier and the first TCP ACK Generation Count, respectively. In response to the determination, the device marks the first TCP ACK packet to be dropped.

    Abstract: A base station (BS) may receive, from a network node, one or more data packets including one or more reflective quality of service (QoS) indicator (RQI) markings. The base station may then determine, based on a value of the one or more RQI markings, one or more active uplink (UL) QoS rules associated with a user equipment (UE). The base station may further determine, based on at least one of one or more timers, the one or more active UL QoS rules, and status information received from the UE, to include or refrain from including the one or more RQI markings in a transmission of the one or more data packets to the UE. Accordingly, in response to the determining that the RQI markings should be included, the base station may then transmit the one or more packets including the RQI markings to the UE.

    Abstract: Apparatuses, systems, and methods for UL traffic throughput enhancements in NSA deployments. A UE may determine that an UL data requirement is substantially greater than a DL data requirement. The UE may perform an UL enhancement procedure based on UL enhancement conditions. The UL enhancement conditions may include determining that a master cell group does or does not operate according to LTE, determining that UL data traffic is only carried via LTE bands or that UL data traffic is split between LTE bands and NR bands, determining that UL carrier aggregation is or is not available, and/or determining that blind secondary cell group addition is supported or is not support by a network. The UE may be configured to perform the at least one UL enhancement procedure thereby enhancing uplink throughput.
