摘要： An infrastructure equipment forms part of a radio access network of a wireless communications network and comprises a transmitter configured to transmit signals to one or more communications devices via a wireless access interface, a receiver configured to receive signals from the one or more communications devices via the wireless access interface, an inter-connecting interface for communicating with one or more other infrastructure equipment of the radio access network of the wireless communications network, and a controller. The controller is configured with the transmitter to transmit a radio network identifier to a communications device, such as a paging identifier, or a radio network temporary identifier, RNTI, which is allocated by the infrastructure equipment for identifying the communications device when allocating communications resources of the wireless access interface for transmitting downlink data to the communications device. After the communications device has entered an inactive connected state, in which the communications device monitors for signals transmitted from the infrastructure equipment, the controller is configured with the transmitter to transmit control signals including the radio network identifier for allocating communications resources of the wireless access interface for the communications device to receive downlink data, to determine whether the communications device is still within a radio coverage area for transmitting signals to and receiving signals from the infrastructure equipment, and if the communications device has left the coverage area, to transmit an indication to the one or more other infrastructure equipment forming part of the radio access network via the inter-connecting interface to trigger a process for transmitting downlink data to the communications device from the one or more other infrastructure equipment. This is for example based on the infrastructure equipment providing, and the communications device using, one of an indication of an acknowledgement preamble, or an indication of a negative acknowledgement preamble, to indicate reception or not of the downlink data transmission.

The method comprises establishing at a radio network infrastructure element there is data available for communication between the radio network infrastructure and the terminal device and transmitting a paging message for the terminal device from the radio network infrastructure element. The paging message comprises an indication of an identifier for the terminal device and an indication of a network allocated resource for use in subsequently communicating the data between the radio network infrastructure element and the terminal device. In response to receiving the paging message the terminal device transmits to the radio network infrastructure element a paging response indicating the terminal device received the paging message, after which the data is communicated between the radio network infrastructure element and the terminal device using the network allocated resource.

摘要： An infrastructure equipment, which forms part of a mobile communications network is configured to transmit signals to and receive signals from one or more communications devices. The infrastructure equipment comprises a receiver configured to receive signals on the uplink from the one or more communications devices via a wireless access interface of the mobile communications network, a transmitter configured to transmit signals on the downlink to the one or more communications devices via the wireless access interface, and a controller configured to control the receiver to receive the signals and to control the transmitter to transmit the signals. One of the communications devices is configured to control transmissions in order to avoid frequency drift. The communications device is configured to receive from the infrastructure equipment an indication of communications resources in which the transmitter can transmit signals to the infrastructure equipment, to determine whether a period required to transmit an uplink transmission to the infrastructure equipment in the indicated communications resources exceeds a predetermined threshold, and if so, subsequently to control the transmitter not to signals to the infrastructure equipment using the indicated communications resources. The communications device may be configured to search for a second infrastructure equipment to which the uplink transmission can be transmitted, and to control the transmitter to transmit signals to the second infrastructure equipment on second communications resources indicated by the second infrastructure equipment rather than using the indicated communications resources of the first infrastructure equipment.
