1. A communications device for transmitting data to or receiving data from a mobile communications network, the mobile communications network including one or more network elements which are arranged to form a wireless access interface for transmitting and receiving the data, the communications device comprising
a transmitter unit configured to transmit signals representing the data on an up-link of the wireless access interface to the mobile communications network, a receiver unit configured to receive signals representing the data transmitted on a down-link from the mobile communications network via the wireless access interface, the wireless access interface providing a plurality of communications resource elements across a frequency range for the down-link and the up-link, the communications resource elements being formed by dividing sub-carriers at different frequencies into a plurality of time periods, one or more of the sub-carriers being provided to form, in the time domain, frequency division multiplexed symbols, each of the time periods comprising a predetermined number of the frequency division multiplexed symbols, wherein the up-link includes a control channel for transmitting signalling information from the communications device to the mobile communications network in accordance with a predetermined format in which signals which representing the signalling information occupy, in the time domain, the predetermined number of frequency division multiplexed symbols of the control channel, and a controller configured to control the transmitter unit to transmit the signals and the receiver unit to receive the signals to transmit or receive the data, and to adapt the transmission of the signals representing the signalling information transmitted, by the transmitter unit, in the control channel to occupy a smaller number of the predetermined number of frequency division multiplexed symbols of the time period of the control channel. |
