Abstract
A communications device transmits/receives data from/to a mobile communications network including one or more network elements arranged to form a wireless access interface for transmitting/receiving data. An 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. A controller is configured to control a transmitter unit to transmit the signals and a receiver unit to receive the signals to transmit or receive the data. The controller is configured 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.
