Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine a decompression failure associated with a header of a received packet and a first real-time transport protocol (RTP) sequence number (SN) interpretation window. In some aspects, the wireless communication device may perform a decompression of the header of the received packet using a second RTP SN interpretation window. The second RTP SN interpretation window may be selected based on at least one of one or more values for the first RTP SN interpretation window or a size of the first RTP SN interpretation window.

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.
