Abstract: The present specification provides a reception method of a machine type communication (MTC) device. The reception method can comprise the steps of: receiving a control channel through the entire system bandwidth on first and second orthogonal frequency division multiplexing (OFDM) symbols of a subframe; and determining whether to receive a data channel only in a reduced bandwidth compared with the system bandwidth from the third symbol of the subframe. At this point, when the control channel does not continue up until a third symbol of the subframe, the data channel can be received in a reduced bandwidth compared with the system bandwidth from the third symbol of the subframe.

Abstract: A User Equipment (UE) is described. The UE decodes an uplink/downlink (UL/DL) reconfiguration downlink control information (DCI) with an enhanced interference mitigation with traffic adaptation (eIMTA)-radio network temporary identifier (RNTI) on a physical downlink control channel (PDCCH).

Abstract: In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.

Abstract: A sensor node among sensor nodes that synchronously switch between a first state and a second state transmits an abnormality notification signal to a collecting apparatus when in the first state and an abnormality occurs at the sensor node. The sensor node, when in the second state, transmits to the communications apparatus, a data signal that differs from the abnormality notification signal. During each interval of the first state, the sensor node enters a third state during a first partial interval of the interval of the first state, and receives and transfers an abnormality notification signal transmitted by another sensor node among the sensor nodes. During each interval of the first state, the sensor node further enters a fourth state during a second partial interval of the interval of the first state and different from the first partial interval, and refrains from receiving the abnormality notification signal.
