The wireless access interface provides plural communications resources divided into time divided units. The method also includes transmitting the data in some or all of the predetermined pattern of communications resources to one or more of the second communications terminals in accordance with device to device communications. The predetermined pattern of communications resources is one of plural patterns of communications resources of the wireless access interface for plural of the time divided units. The plural patterns of communications resources are predetermined for a reduction in latency when transmitting the data from the first communications terminal and/or reducing in signaling overhead required to transmit the data. ## Claims ### Claim 1 A method of allocating communications resources from an infrastructure equipment forming part of a wireless communications network, to a communications terminal, the method comprising receiving a request for communications resources from the communications terminal, in response to the request, transmitting from the infrastructure equipment, to the communications terminal one or more identifying indications to communications resources of the wireless access interface, each of the identifying indications identifying a predetermined pattern of communications resources of the wireless access interface, divided in time into a time divided units, for a plurality of the time divided units. ### Claim 2 (depends on 1) A method as claimed in claim 1, wherein the one or more predetermined patterns of communications are pre-configured in the communications terminal, and the infrastructure equipment. ### Claim 3 (depends on 1) A method as claimed in claim 1, wherein the method comprises transmitting from the infrastructure equipment, an indication of the plurality of predetermined patterns of communications resources, the indication being transmitted by the infrastructure equipment for receipt by communications terminals. ### Claim 4 (depends on 3) A method as claimed in claim 3, wherein the transmitting the indication comprises transmitting the indication of the plurality of predetermined patterns of communications resources from the infrastructure equipment, a plurality of times, the infrastructure equipment changing the plurality of predetermined patterns of communications resources between one time and the next. ### Claim 5 (depends on 1) A method as claimed in claim 1, wherein the predetermined pattern of communications resources identifies different communications resources in different time divided units, ### Claim 6 A base station for use in a mobile telecommunications system, the base station being configured to communicate with one or more terminals of the system, the system comprising one or more infrastructure nodes configured to communicate with the one or more terminals, wherein the base station is further configured to receive a request for communications resources from one of the communications terminals, in response to the request, to transmit to the communications terminal one or more identifying indications to communications resources of the wireless access interface, each of the identifying indications identifying a predetermined pattern of communications resources of the wireless access interface, divided in time into a time divided units, for a plurality of the time divided units. ### Claim 7 Circuitry for a base station for use in a mobile telecommunications system, the base station configured to communicate via a wireless interface with one or more terminals of the system, the system comprising one or more infrastructure nodes configured to communicate with the one or more terminals via the wireless interface, wherein the circuitry comprises a controller element and a transceiver element configured to operate together to to receive a request for communications resources from one of the communications terminals, in response to the request, to transmit to the communications terminal one or more identifying indications to communications resources of the wireless access interface, each of the identifying indications identifying a predetermined pattern of communications resources of the wireless access interface, divided in time into a time divided units, for a plurality of the time divided units.
