Abstract: A method of evaluating whether to handover a terminal device from communicating with a first network infrastructure element associated with a first communication cell to communicating with a second network infrastructure element associated with a second communication cell in a wireless telecommunications system. The method includes establishing an indication of radio conditions associated with a path between the terminal device and the first network infrastructure element; and establishing an indication of a second measurement of radio conditions associated with a communication path between the terminal device and the second network infrastructure element; and determining whether to handover the terminal device from communicating with the first network infrastructure element to the second network infrastructure element based on a comparison of the indication of the first measurement of radio conditions and the indication of the second measurement of radio conditions.

Abstract: An infrastructure equipment for a mobile communications network includes plural antennas, and is configured in a first mode of operation to transmit, from each of the plural antennas, reference signals in communications resource elements of the wireless access signals allocated to the plural antennas. The reference signals are transmitted in different communications resource elements of the wireless access interface for each antenna, so that a receiver can estimate a communications channel for each of the antennas, from the antennas to the receiver, from the transmitted reference signals. The infrastructure equipment is configured to switch between transmitting signals representing different data segments between subsets of the plural antennas to a second communications device, the signals being transmitted from each antenna subset representing different data segments for transmission to the second communications device, the transmitted signals being switched in at least one of time or frequency in accordance with a mapping.

Abstract: A communications device acting as a relay device configured to communicate with an infrastructure equipment of a mobile communications network and a receiving communications device operating with the mobile communications network. The communications device acting as the relay device comprises receives signals representing protocol data units formed from one or more service data units via a first wireless access interface from the infrastructure equipment according to a first automatic repeat request protocol for transmission to the receiving communications device, transmits signals representing the received protocol data units via a second wireless access interface to the receiving communications device according to a second automatic repeat request protocol, and stores, in a buffer, the protocol data units received from the infrastructure equipment according to the first automatic repeat request protocol.

Abstract: A terminal device comprising telecommunications transceiver circuitry configured to transmit data to and receive data from a communication node in a telecommunications network and controller circuitry configured to control the transceiver circuitry is described. The controller circuitry is configured to: determine the speed of movement of the terminal device; and control the transceiver circuitry to transmit an uplink reference signal that allows the communication node to determine the channel quality between the communication node and the terminal device, wherein the rate of transmission of the uplink reference signal is determined by the speed of movement of the terminal device.
