Infrastructure equipment, communications device and methods
First Claim
1. An infrastructure equipment for a mobile communications network, the infrastructure equipment comprising:
- a transmitter configured to transmit downlink signals to one or more communications devices via a wireless access interface comprising a plurality of communications resource elements;
a receiver configured to receive uplink signals from the one or more communications devices via the wireless access interface; and
processing circuitry configured to;
control the transmitter to transmit the downlink signals to the one or more communications devices and control the receiver to receive the uplink signals from the one or more communications devices, wherein the wireless access interface comprises a communications channel in which each of a plurality of time units comprises communications resource elements in time and frequency for allocation to transmit messages to the one or more communications devices;
identify, for each of the plurality of time units, first communications resource elements of the communications channel which cannot be allocated to transmit the messages to a communication device of the one or more communications devices;
determine, with respect to a time unit of the plurality of time units as a reference time unit, a number of the communications resource elements of the communications channel for repeatedly transmitting one or more message units to the communications device a plurality of times in the reference time unit;
identify, for each time unit of the plurality of time units, a pattern of the communications resource elements for a repeated transmission of the one or more message units within each time unit and determined with respect to the reference time unit, wherein the pattern of the communications resource elements for each of the plurality of time units excludes the first communications resource elements of the communications channel which cannot be allocated to the one or more communications devices; and
control the transmitter to transmit the one or more message units to the communications device via the identified pattern of the communications resource elements in the plurality of time units of the wireless access interface.

Abstract
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.
