The present application relates to devices and components including apparatus, systems, and methods for user equipments and network components performing or assisting in packet filtering operations.

Technologies for packet filtering for protocol data unit sessions

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.

Systems and methods for managing transmission control protocol (TCP) acknowledgements

Apparatuses, systems, and methods for Reflective Quality of Service (RQoS) enhancements. Methods may include enhancements for both UE behavior and network function behavior. Network function behaviors may include enhancements to UPF behavior and SPF behavior. Enhancements to RQoS may include methods for resetting an RQoS indicator (RQI) bit for downlink packets of a flow destined for a UE, methods for generating a flow ID to include in a SDAP header destined for a UE, methods for using the flow ID to limit L3 and L4 header parsing, methods for sending/receiving feedback regarding processing of the RQI bit, methods for maintaining a QFI mapping table, methods for skipping parsing of SDAP header fields, methods for specifying and signaling a QoS Flow Identifier (QFI) range to a UE, methods for limiting downlink header parsing, methods for updating a QFI, and methods for performing high efficiency RQoS processing.

Reflective QoS enhancements

This disclosure relates to techniques for performing wireless communications including filtering packets for transmission between a user equipment (UE) and a base station. Techniques for filtering packets, at a lower layer and/or baseband processor, using higher layer information, such as a flow identifier, are disclosed. A device may generate various tables and may use the tables to filter packets efficiently.

Enhanced packet filtering

Embodiments may relate to identifying, by a baseband processor, an amount of data in a data radio bearer (DRB) buffer of the baseband processor. Embodiments further relate to determining, by the baseband processor based on an indication from an application processor of the electronic device, an amount of data in at least one buffer of the application processor. Embodiments further relate to generating, by the baseband processor based at least in part on the amount of data in the DRB buffer and the amount of data in the at least one buffer of the application processor, a buffer status report (BSR). Other embodiments may be described or claimed.

Buffer status report (BSR) data reporting based on application processor (AP) assistance

A client device in a wireless network accesses a queue comprising Transmission Control Protocol Acknowledgement (TCP ACK) packets, at least some of which include packet descriptors, each with a flow identifier indicating a TCP flow associated with the packet, 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 first 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.

Coordinated internet protocol packet filtering

A communication device is described comprising a media output unit, a receiver configured to receive a packet of a sequence of packets, the packet comprising a compressed header and media payload and a processor configured to detect whether decompression of the compressed header is prevented, and, if decompression of the compressed header is prevented, to determine a sequence number of the media payload, extract the media payload from the packet and forward the media payload and an indication of the sequence number to the media output unit.

Apparatus adapted for maintaining receiving data quality and method for receiving data

A user equipment device (UE) may create efficient Packet Data Convergence Protocol (PDCP) status reports. The UE may receive PDCP packets from multiple radio access technologies (RATs) using the same bearer or same RAT using split bearers. The UE may identify packets that the UE should have received but did not, and may create a status report based on the sequence numbers (SNs) of the packets that the UE failed to receive or based on the SNs of the successful packets. The report may include the SNs of the packets, in addition to a bit-length of the SNs and/or a starting point of the SNs in the status report. Alternatively, the report may include the SN of a first packet that the UE failed to receive and offset values (relative to the SN of the first packet) for the other packets that the UE failed/succeed to receive.

PDCP status reports using sequence numbers or sequence number offsets

In various embodiments, a method for compressed transmission of data packet header fields in a packet-oriented data stream may comprise: estimating in advance a data packet header field in a packet-oriented data stream from at least one preceding data packet header field; forming a piece of comparison information which indicates the difference between the data packet header field and the data packet header field estimated in advance using the transmitter neural network; transmitting the comparison information as a compressed data packet header field from the transmitter to a receiver; estimating in advance the data packet header field from at least one already transmitted data packet header field in the packet-oriented data stream using the receiver neural network; and generating the data packet header field from the data packet header field estimated in advance using the neural network of the receiver and from the transmitted piece of comparison information.

Method for the compressed transmission of data packet header fields in a packet-oriented data stream, method for compressing data packet header fields in a packet-oriented data stream, method for decompressing data packet header fields in a packet-oriented data stream, compression/decompression system, compression apparatus and decompression apparatus
