Abstract: A transmitter device may be configured to perform to robust header compression optimization to improve channel throughput. In some aspects, the transmitter device may establish a first base context between the transmitter device and a receiver device, wherein a first context identifier is assigned to the first base context, establish a replication context between the devices, wherein the replication context is derivable from the first base context and a second context identifier is assigned to the replication context, and identify a new context. Further, the transmitter device may reassign the first context identifier to the new context, disassociate the second context identifier from the first context identifier, establish a second base context between the devices, wherein a third context identifier is assigned to the second base context, and associate, based on the replication context being derivable from the second base context, the second context identifier to the third context identifier.

Abstract: A wireless communication utilizes robust header compression efficiently with improved improvements in packet data convergence protocol configuration for increasing channel throughput. A user equipment (UE) receives a configuration indicating a first listing of header generic options that are supported between the UE and a first base station. The UE obtains a first packet including a first uncompressed header that indicates header parameters. The UE determines whether the header parameters in the first uncompressed header corresponds to at least one header generic option in the first listing of header generic options. The UE communicates the first packet that may have a first compressed header based on a first header compression profile or an uncompressed header depending on whether the header parameters in the first uncompressed header corresponds to at least one header generic option in the first listing of header generic options.

Abstract: Various aspects include methods for Transmission Control Protocol (TCP)/Internet Protocol (IP) (TCP/IP) packet transmission and compression of headers for TCP/IP packet transmission. Various embodiments may include a packet data convergence protocol (PDCP) layer of a processing device applying least significant bit (LSB) encoding to a TCP Timestamp (TS) option of a TCP/IP packet using an offset parameter of zero to generate a compressed header in response to determining that a TCP TS field of the TCP/IP packet and a TCP TS field of a last TCP/IP packet transmitted have a same value. In some embodiments, a Timestamp Value (TSVal) field or a Timestamp Echo Reply (TSEcho) field of the TCP TS option of the compressed header may have a size of one byte.

Abstract: Systems, methods, and computing platforms for context identifier allocation for data packet header compression are provided. Exemplary implementations may: obtain a first packet of a stream to be sent using a header compression protocol; determine a context identifier (CID) to associate with the stream based, at least in part, on a packet type of the first packet; generate a compressed header for the first packet according to the header compression protocol and based on the determined CID; and transmit the first packet with the compressed header.
