An infrastructure equipment for a mobile communications network includes a transmitter and a receiver for transmitting and receiving signals via a wireless access interface to one or more communications devices. The infrastructure equipment is configured to identify, for each of plural time units, communications resource elements of a down-link communications channel which cannot be allocated to transmit messages to one of the communications devices, to determine, with respect to one of the plural time units as a reference time unit, a number of communications resource elements of the communications channel for repeatedly transmitting one or more message units to the communications device plural times in the reference time unit, to identify, for each of the plural time units, a pattern of the communications resource elements for the repeated transmission of the one or more message units, within each time unit, determined with respect to the reference time unit.
