Abstract: An infrastructure equipment that transmits a radio network identifier to a communications device 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, the infrastructure equipment transmits control signals including the radio network identifier for allocating communications resources of the wireless access interface for the communications device to receive downlink data, determine whether the communications device is still within a radio coverage area of the infrastructure equipment, and if the communications device has left the coverage area, transmit an indication to the one or more other infrastructure equipment 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.

Abstract: A method of operating a terminal device to establish a radio resource control connection with network infrastructure equipment in a wireless telecommunications network, wherein the terminal device is associated with a previously-allocated temporary identifier that identifies the terminal device within the wireless telecommunications network; the method comprising: transmitting a first message to the network infrastructure equipment comprising an indication of a first portion of the temporary identifier; and transmitting a second message, which is separate from the first message, to the network infrastructure equipment comprising an indication of a second portion of the temporary identifier.

Abstract: Location of an electronic device is determined using signals received from a first set of reference radios. The first set of reference radios include at least one secondary reference radio, each secondary reference radio established as a secondary reference radio by registering a corresponding location with a server. The corresponding location of the secondary reference radio is determined as a function of signals received by the secondary reference radio from a second set of reference radios. The second set of reference radios include radios qualified as reference radios in a database of primary se reference radios and secondary reference radios, each primary reference radio being a fixed-location radio device.

Abstract: An interface of a terminal switches between at least one active state (283) and a sleep state (281) according to a schedule (200). Uplink control data is transmitted which is indicative of a temporary prolongation (209) of the at least one active state (283).

Abstract: A wireless telecommunications system including a terminal device; first infrastructure equipment operable to communicate with the terminal device using a first radio access technology (RAT) and second infrastructure equipment operable to communicate with the terminal device using a second RAT. During a handover procedure for handover from the first infrastructure equipment as a source master infrastructure equipment to a third infrastructure equipment as a target master infrastructure equipment, the second infrastructure equipment is operable to communicate with the third infrastructure equipment using an interface associated with the second RAT so as to allow information necessary for completing the handover to be exchanged between the first infrastructure equipment and the third infrastructure equipment via the second infrastructure equipment.

Abstract: A plurality of payload messages (502, 505, 508) is communicated on a radio link of a cellular network between a terminal (130) and an access node (112) of the cellular network. Each one of the plurality of payload messages (502, 505, 508) includes a data packet (501) encoded according to a given redundancy version (371-373). The number of the plurality of payload messages (502, 505, 508) may be dynamically and flexibly adjusted in some embodiments. Examples are given which may be applied for coverage enhancement in the Internet of Things or Machine Type Communication domain.

Abstract: An access point node (240) comprises a first interface configured to communicate with a radio access node (112) of a cellular network (110) via a radio link (211) and further comprises a second interface configured to communicate with a terminal (130) via a further radio link (212). The access point node (240) is configured to establish an end-to-end connection (250) with a user-plane gateway node (117, 118) of the cellular network (110) in response to receiving an attach message from the terminal (130).
