Abstract
A communications device transmits/receives data to/from a mobile communications network including one or more network elements forming a wireless access interface for transmitting/receiving the data. An up-link includes a shared channel for transmitting the data to the mobile communications network. A controller controls a transmitter and receiver to transmit to the mobile communications network a request to transmit data in a smaller number of frequency division multiplexed symbols than available on the shared channel, to receive from the mobile communications network an indication of a sub-set of the predetermined number of frequency division multiplexed symbols in which the communications device should transmit the data on the shared channel, and to transmit signals representing the data in the shared channel to occupy a smaller number of frequency division multiplexed symbols than the number of the predetermined number of frequency division multiplexed symbols of the time period of the shared channel.
