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.
