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.

Abstract: An infrastructure equipment (eNodeB) is configured to transmit a paging notification which indicates that configuration information which is broadcast in a cell to all communications devices which are configured to operate in accordance with a network controlled function has changed. Communications devices which are configured to perform the network controlled function are provided with an indication that they should receive the configuration information which is broadcast in order to reconfigure the network controlled function. A communications device which is not configured to perform the network controlled function may not recognise the paging notification or at least may detect that it does not need to receive the updated configuration information for the network controlled service. Such communications devices may therefore remain in an idle mode thereby saving power.

Abstract: A method of transmitting blocks of data in a wireless telecommunications system in which blocks of data are transmitted a plurality of times. When a first block of data becomes available for transmission an initial selection of transmission resources for a plurality of transmissions of the first block of data in a corresponding plurality of time periods is made, and transmissions of the first block of data are started. While there are still transmissions of the first block of data which remain to be made, a second block of data becomes available for transmission. In response to this, the initial selection of transmission resources for the remaining repeat transmissions of the first block of data is modified to increase the amount of resource available for transmitting the second block of data during the time periods in which repeat transmissions of the first block of data remain to be made.
