Communications device, infrastructure equipment and methods for receiving downlink control information

Circuitry for an infrastructure equipment for transmitting data to or receiving data from communication devices in a mobile communications network, the circuitry configured to:

• transmit data via a wireless access interface, the data provided in a radio frame that is divided into a plurality of time divided temporal units with a downlink control channel and a downlink shared channel included in each temporal unit;
• and
• transmit downlink control channel information in one or more control channel elements of the downlink control channel included in the radio frame, wherein the one or more control channel elements in which the downlink control channel information is transmitted is one of a plurality of sets of possible control channel elements in which infrastructure equipment can transmit the downlink control information in one of the temporal units of the radio frame, wherein
• the downlink control channel information is transmitted in at least one of (i) a first sub-set of the plurality of possible sets of control channel elements in one or more of the temporal units of the radio frame according to a fixed aggregation level, and (ii) a second sub-set of possible control channel elements which is selected from the plurality of possible sets of the control channel elements in one or more temporal units according to a configurable aggregation level.

A method performed by infrastructure equipment in a mobile communications network for transmitting downlink control information to communication terminals, the method comprising:

• transmitting data via a wireless access interface, the data provided in a radio frame that is divided into a plurality of time divided temporal units with a downlink control channel and a downlink shared channel included in each temporal unit;
• and
• transmitting downlink control channel information in one or more control channel elements of the downlink control channel included in the radio frame, wherein the one or more control channel elements in which the downlink control channel information is transmitted is one of a plurality of sets of possible control channel elements in which infrastructure equipment can transmit the downlink control information in one of the temporal units of the radio frame, wherein
• the downlink control channel information is transmitted in at least one of (i) a first sub-set of the plurality of possible sets of control channel elements in one or more of the temporal units of the radio frame according to a fixed aggregation level, and (ii) a second sub-set of possible control channel elements which is selected from the plurality of possible sets of the control channel elements in one or more temporal units according to a configurable aggregation level.
