A method of communicating data between a base station and a plurality of terminal devices in a wireless telecommunications system is described. The method comprises transmitting data from the base station to the plurality of terminal devices in a multicast transmission and transmitting response signals from the terminal devices to the base station to indicate whether or not the respective terminal devices have successfully received the multicast transmission. The use of a multicast transmission provides an efficient mechanism for communicating the same data to a plurality of terminal device, for example as might be desired in a machine-type communication network. In combination with this, the use of individual response signals, such as ACK/NACK signalling, from the terminal devices allows the base station, or other entity, to track which terminal devices have indicated successful receipt of the multicast transmission, and to instigate an appropriate re-transmission protocol accordingly.
A method of operating a base station for communicating data in a wireless telecommunications system, the method comprising:
A base station for communicating data with a plurality of terminal devices in a wireless telecommunications system, the base station including circuitry that is configured to transmit data to the plurality of terminal devices in a multicast transmission,
