A communications device transmitting/receiving data to/from a mobile communications network includes a transmitter to transmit data to the mobile communications network via a wireless access interface, a receiver to receive data from the mobile communications network via the wireless access interface, and a controller. The wireless access interface includes plural time divided temporal units and in each temporal unit a down-link control channel and a down-link shared channel. The temporal units may be sub-frames of an LTE carrier. The controller can control the receiver to receive downlink control channel information transmitted by the mobile communications network in one or more control channel elements of the downlink control channel, and to receive the downlink control channel information by searching the downlink control channel in a predetermined sub-set of plural possible sets of control channel elements in one or more of the temporal units according to a fixed aggregation level. |
