1. Integrated circuitry for infrastructure equipment for use with a wireless telecommunications network, the integrated circuitry comprising:
a transceiver configured to
receive, from a first terminal device of the wireless telecommunications network, the first terminal device being configured to exchange signals with each of a plurality of second terminal devices of the wireless telecommunications network, when the first terminal device provides a local cell for providing wireless connectivity for the plurality of second terminal devices, and
exchange signals with the infrastructure equipment, suitability information indicative of the suitability of one or more other terminal devices or infrastructure equipment of the wireless telecommunications network to exchange signals with each of the plurality of second terminal devices to provide for that second terminal device another local cell, the infrastructure equipment providing a cell including the first terminal device, at least a portion of the local cell being provided within the cell of the infrastructure equipment; and
a control circuit configured to
determine, on the basis of the suitability information, whether one of the one or more other terminal devices or infrastructure equipment of the wireless telecommunications network is more suitable for serving one or more of the second terminal devices served by the first terminal device; and
in the case that one of the one or more other terminal devices or infrastructure equipment of the wireless telecommunications network is determined to be more suitable for serving one or more of the second terminal devices served by the first terminal device, control the transceiver to
transmit information indicative of the identified one or more other terminal devices or infrastructure equipment to the first terminal device;
receive reservation information indicative of one or more of the allocated communication resources which are reserved for use by another one of the other terminal devices in the group;
randomly select the one of the allocated communication resources from the allocated communication resources which are not reserved for use by another one of the terminal devices in the group; and
if it is determined that the transceiver has received an acknowledgement message, receive updated reservation information indicative of one or more of the allocated communication resources which are reserved for use by the terminal device, and transmit a second signal to the wireless telecommunications network using one of the communication resources reserved for use by the terminal device within a predetermined period of time.
