Abstract: A radio communication system includes: a plurality of cells having different scrambling sequences, respectively, wherein at least two cells communicate with at lease two user terminals connected to different serving cells; and a controller which controls the plurality of cells and provides a single scrambling sequence to said at least two cells and said at least two user terminals for control signal transmission and reception.

Abstract: A base station includes a transmitter configured to transmit a downlink control information to a user equipment, the downlink control information being generated based on one of (1) a first uplink allocation information indicating a first frequency block corresponding to a first plurality of subcarriers which are contiguous in frequency and (2) a second uplink allocation information indicating a second frequency block corresponding to a second plurality of subcarriers which are contiguous in frequency and a third frequency block corresponding to a third plurality of subcarriers which are contiguous in frequency, the second frequency block and the third frequency block being separated in frequency.

Abstract: In one embodiment, an apparatus, a system or a network (1) sets a discovery period for a node (2B). The discovery period is a time period in which the node (2B) sends a signal (e.g., PSS, SSS, and CRS) necessary for cell detection and radio measurement performed by a user equipment (3A) before a cell (20B), controlled by the node (2B), is to be turned on in order to send a signal (e.g., data signal) for either or both of user data reception and transmission. It is achieved, for example, that the user equipment (3A) is able to detect the signal (e.g., PSS, SSS, and CRS) for cell detection and radio measurement in the discovery period by using legacy behavior of radio measurement.
