Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a stream of RTP data packets over a wireless channel and applies ROHC decompression to decode the packets. Upon a failure of ROHC decompression, the apparatus identifies the RTP sequence number (SN), RTP Timestamp (TS), and PDCP receive time (RT) of a prior successfully decoded packet, and the PDCP SN and PDCP RT of the failed packets. Using the identified information, the apparatus estimates the RTP SN and RTP TS of each of the failed packets. The apparatus decodes the packets using the estimated information.

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.
