Abstract: Provided are a base station, whereby the erroneous detection of control information can be reduced, thereby preventing the degradation of the system throughput. A base station maps a downstream allocation control information unit, which is addressed to a terminal, to a first resource region, which can be used for any of a downstream control channel region and a downstream data channel region, or to a second resource region, which can be used only for the downstream control channel, so as to transmit the downstream allocation control information unit. In the base station, a control unit establishes a scale of the PDCCH region, and a transmission region establishing unit establishes, on the basis of a scale value established by the control unit, a mapping region to which the DCI is mapped within the R-PDCCH region and the PDCCH region.

Abstract: A method for use in endoscopic investigations comprises the steps of providing an endoscopic insertion member with a suction line, inserting the endoscopic insertion member with the suction line into a patient, and visually inspecting organic tissues inside the patient with the endoscopic insertion member. To collect a fluid specimen, a port cover on the suction line is moved with respect to the suction line to open a port in the line. A specimen vial is coupled to the suction line at the opened port so that the suction line communicates with the vial. A vacuum is applied to the suction line to draw a fluid specimen into the vial. Subsequently, the vial is detached from the suction line, and the port cover moved back into position to again cover the port.
