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.

Claim (Index 1):
An infrastructure equipment for a mobile communications network, the infrastructure equipment comprising,\n a transmitter configured to transmit signals to one or more communications devices via a wireless access interface comprising in each of a plurality of time divided units a plurality of communications resource elements, and a receiver configured to receive signals from the one or more communications devices via the wireless access interface, and a controller configured to control the transmitter and the receiver to transmit the signals to the one or more communications devices and to receive the signals from the one or more communications devices, wherein the transmitter includes a plurality of antennas, and the controller is configured to control the transmitter, in a first mode of operation, to transmit, from each of the plurality of antennas, reference signals in communications resource elements of the wireless access signals allocated by the controller to each of the plurality of antennas, the reference signals being transmitted from each of the antennas 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 plurality of antenna, from the antenna to the receiver, from the transmitted reference signals, and to transmit, from each of the plurality of antennas, signals representing data in communications resource elements allocated by the controller for transmitting the data to a first of the communications devices, the signals representing the data being transmitted contemporaneously in the same communications resource elements from each antenna with the reference signals, and, in a second mode of operation to determine a mapping for transmitting different data segments from each of a plurality of subsets of the plurality of antennas to a second communications device using communications resource elements, which, for each antenna subset, are separated in at least one of time or frequency, to transmit an indication of the mapping for transmitting the data segments from each of the subsets of antennas to the second communications device, to switch between transmitting signals representing the different data segments between the subsets of the plurality of antennas to the 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 the mapping so that to detect the data a receiver is required to generate a smaller number of channel estimates than the receiver would be required to estimate if the data was transmitted in the first mode, wherein the communications resource elements which are used to transmit the reference signals from each antenna are the same in the first mode of operation as the second mode of operation.
