11. The method according to claim 7 , wherein a continuous time period which defines the communications resources of the reference region is the same as a continuous time period between periodic uplink pre-emption indicator monitoring occasions of the wireless access interface within which the communications device monitors for an uplink pre-emption indicator from the infrastructure equipment.

12. The method according to claim 11 , wherein each of the uplink pre-emption indicator monitoring occasions are located at the start of the reference region associated with the uplink pre-emption indicator that the communications device monitors for in that uplink pre-emption indicator monitoring occasion.

13. The method according to claim 11 , wherein each of the uplink pre-emption indicator monitoring occasions are located before the start of the reference region associated with the uplink pre-emption indicator that the communications device monitors for in that uplink pre-emption indicator monitoring occasion.

14. The method according to claim 7 , wherein a continuous time period which defines the communications resources of the reference region is the same as a continuous time period which defines the uplink communications resources.

15. The method according to claim 7 , comprising:

receiving the uplink pre-emption indicator in downlink control information received from the infrastructure equipment, the downlink control information comprising one or more other uplink pre-emption indicators.

16. The method according to claim 15 , wherein the downlink control information is transmitted to one or more other communications devices in addition to the communications device, and each of the other uplink pre-emption indicators are for receipt by one of the other communications devices.

17. The method according to claim 15 , wherein one or more of the other uplink pre-emption indicators are for receipt by the communications device and each of the one or more of the other uplink pre-emption indicators indicate that at least a portion of the uplink communications resources are allocated for the transmission of a signal by one of one or more other communications devices, the at least the portion of the uplink communications resources being located within communications resources of a reference region associated with each of the one or more of the other uplink pre-emption indicators.

18. The method according to claim 1 , wherein the manner in which the uplink communications resources are allocated to the communications device comprises receiving an uplink grant comprising an allocation of the uplink communications resources from the infrastructure equipment.

19. A communications device for transmitting data to or receiving data from an infrastructure equipment forming part of a wireless communications network, the communications device comprising:

transmitter circuitry configured to transmit signals to the infrastructure equipment via a wireless access interface provided by the wireless communications network,

receiver circuitry configured to receive signals from the infrastructure equipment via the wireless access interface, and

controller circuitry configured in combination with the receiver circuitry and the transmitter circuitry
