Dependent claims

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;
and
to transmit a first signal to the wireless telecommunications network using a selected one of the allocated communication resources;
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.

A method of controlling infrastructure equipment for use with a wireless telecommunications network, the method comprising:

controlling a transceiver of the infrastructure equipment to transmit information indicative of a plurality of communication resources, each of the indicated plurality of communication resources being allocated for use by each terminal device in a group of terminal devices in transmitting signals to the wireless telecommunications network via the infrastructure equipment on a contention basis;
and
monitoring the allocated communication resources for signals received at the transceiver of the infrastructure equipment from the terminal devices of the group, the monitoring comprising performing an operation with respect to each of the allocated communication resources to determine whether a signal has been received by the transceiver via that communication resource from a single identified one of the terminal devices of the group;
and
if it is determined that a signal has been received by the transceiver of the infrastructure equipment via one of the allocated communication resources from a single identified one of the terminal devices of the group, controlling the transceiver to transmit an acknowledgement message to the identified terminal device and transmit, to each of the terminal devices in the group, reservation information indicative of one or more of the allocated communication resources which are reserved for use by the identified terminal device.
