1. An apparatus for wireless communication at a receiver, comprising:
at least one memory; and
at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to:
receive a first message comprising a first packet data convergence protocol (PDCP) sequence number (SN);
receive a second message comprising a second PDCP SN, wherein the second message is associated with a second real-time transport protocol (RTP) SN, wherein the second message is not transmitted with a robust header compression (ROHC) header having a RTP SN field; and
derive the second RTP SN based on at least one of:
a first RTP SN of the first message,
the first PDCP SN,
the second PDCP SN, or
a second RTP SN field of a second PDCP header, wherein the second message comprises the second PDCP header.
