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.
