1. A method of controlling a terminal device for use with a wireless telecommunications network as one of a group of terminal devices, the method comprising:
controlling a transceiver of the terminal device
to receive information indicative of a plurality of communication resources, each of the indicated plurality of communication resources being allocated for use by the terminal devices of the group in transmitting signals to the wireless telecommunications network on a contention basis;
to transmit a first signal to the wireless telecommunications network using a selected one of the allocated communication resources;
to 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;
to 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, controlling the transceiver to receive updated reservation information indicative of one or more of the allocated communication resources which are reserved for use by the terminal device, and to transmit a second signal to the wireless telecommunications network using one of the communication resources reserved for use by the terminal device;
determining whether the transceiver has received an acknowledgement message from the wireless telecommunications network;
if it is determined that the transceiver has received an acknowledgement message, determining that the first signal has been successfully received by the wireless telecommunications network; and
if it is determined that the transceiver has not received an acknowledgement message, controlling the transceiver to re-transmit the first signal to the wireless telecommunications network,
wherein a random selection operation is performed by randomly selecting the one of the allocated communications resources for transmitting the first signal from the plurality of communication resources allocated to the group of terminal devices.
