1. A communications device for operating with a wireless communications network, the communications device comprising:
circuitry configured to receive a downlink signal transmitted via a wireless access interface formed by the wireless communications network, the wireless access interface comprising in a frequency dimension resource elements, each of the resource elements for carrying a sub-carrier of an Orthogonal Frequency Division Multiplexed (OFDM) symbol, the resource elements being formed in the frequency dimension into blocks of resource elements, and in a time dimension the wireless access interface is divided into time units, each of the time units for carrying a number of OFDM symbols, the downlink signal comprising a plurality of component-signals selected from a set of component-signals, each of the component-signals from the set of component-signals being formed from a sequence of signal samples transmitted in one of the blocks of resource elements and in one of the time units by the number of OFDM symbols, each of the component-signals being detectable by a narrower bandwidth receiver, and each of the plurality of component-signals is transmitted in one of the blocks of resource elements and one of the time units, the plurality of selected component signals being received in the selected blocks of resource elements as a wider bandwidth signal.
