PDCP is located in the Radio Protocol Stack in the UMTS/LTE/5G air interface on top of the RLC layer . PDCP provides its services to the RRC and user plane upper layers, e.g. IP at the UE or to the relay at the base station.
Read moreWhat is the function of PDCP layer?
From UMTS, the main function of the PDCP layer has been the header compression of IP packets – this is the reason why it is called the Packet Data Convergence Protocol. In LTE, the PDCP layer has evolved to support a security function; that is, integrity protection and ciphering.
