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.
