    Abstract: A communications device is provided, which is configured to transmit or receive signals via a wireless access interface provided by the wireless communications network to or from one or more infrastructure equipment. The communications device is configured, at the time of a Radio Resource Control (RRC) connection establishment procedure, to receive a first message from one of the infrastructure equipment comprising an indication that the infrastructure equipment is capable of operating in accordance with a packet data convergence protocol (PDCP) in accordance with a first radio access technology, to establish a PDCP entity based on the received indication, and to transmit a second message to the infrastructure equipment comprising an indication that the communications device is capable of operating in accordance with one or both of the PDCP in accordance with the first radio access technology and a PDCP in accordance with a second radio access technology.
