PDCP is an abbreviation for Packet Data Convergence Protocol. It is one of the layers of the Radio Traffic Stack in UMTS/LTE and performs IP header compression and decompression, transfer of user data and maintenance of sequence numbers for Radio Bearers which are configured for lossless serving radio network subsystem (SRNS) relocation.
