    Abstract: The present disclosure relates to an apparatus and a method for performing transmission and reception of wireless power. The apparatus comprises: a transmission signal processing unit configured to generate a transmission data signal and perform a modulation and an amplification; a transmission antenna configured to convert the transmission data signal into an RF signal and transmit the RF signal; at least one reception antenna configured to receive at least one of the RF signal or an external signal received from the outside; a wireless power reception unit configured to harvest power from the RF signal received through the at least one reception antenna; and a reception signal processing unit configured to demodulate the external signal received through the at least one reception antenna. Since the RF signal, which is radiated by the apparatus itself, is received again and utilized for power charging, energy can be recycled.

    Abstract: A method and device for receiving downlink data in a wireless communication system are discussed. The method performed by a terminal includes receiving, from a base station, first downlink control information through a physical downlink control channel (PDCCH) or a short PDCCH (sPDCCH), wherein the first downlink control information schedules a plurality of short physical downlink shared channel (sPDSCH) regions based on a first transmission time interval (TTI)-based radio frame structure, and each of the plurality of the sPDSCH regions is included in a different plurality of short subframes based on the first TTI-based radio frame structure, respectively; and receiving, from the base station, first downlink data in the plurality of the sPDSCH regions based on the first downlink control information, wherein the first TTI-based radio frame structure has a shorter interval than a second TTI-based radio frame structure for the PDSCH region in which second downlink data is transmitted.
