Abstract: A communications device configured to detect one or more beams of signals transmitted by each of a plurality of infrastructure equipment forming a plurality of cells of the wireless communications network, each of the beams being separately identifiable and forming a directional bias with respect to a location of the infrastructure equipment. The communications device is configured to perform measurements for evaluating a quality of the plurality of cells including one or more beams on signals received from each of the detected beams, to determine from the evaluation of each of the cells, and if one or more of the cells satisfies predetermined conditions to perform a process for identifying one or more of the cells which should be used by the communications device for transmitting data.

Abstract: A communications device acting as a rely device is configured to transmit a buffer status report message indicating that the buffer is storing data received from the infrastructure equipment for transmission to a remote communications device, when predetermined conditions are satisfied or a trigger event occurs so that the transmission of the data to the remote communications device can make more efficient use of communications resources to transmit the data or the remote communications device receives the data when the remote communications device is in a state in which it should receive the data, for example when not in a reduced power state.

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.
