A telecommunications system comprises one or more transmitters operable to transmit a first carrier C1 over a first frequency bandwidth and a second carrier C2 over a second frequency bandwidth. During a first time period T1 data receivable by a first class of terminal (a machine-type communication (MTC) terminal) is transmitted on the first carrier and data receivable by a second class of terminal (a Long Term Evolution (LTE) type terminal) is transmitted on the second carrier.

During the first time period control data is transmitted on the first carrier to enable the second class of terminal to maintain synchronisation with the first carrier. In this way the invention allows the first carrier to be time multiplexed between the transmission of LTE data using carrier aggregation and the transmission of MTC data.
