    Abstract: A broadband patch antenna comprises a substrate, a ground plate attached to one surface of the substrate, a radiation plate attached to the other surface of the substrate opposite the one surface of the substrate, and a feed line attached to the other surface of the substrate and having one end connected to the radiation plate. The feed line comprises a first line and a second line. The ground plate has the shape of capital “L” having a first groove, a second groove, and a third groove, and may not comprise a portion corresponding to the radiation plate. The first groove is positioned at a first portion which corresponds to a connection portion between the first line and the radiation plate, the second groove is positioned at a second portion which corresponds to a connection portion between the second line and the radiation plate, and the third groove may be positioned so as to be spaced apart from the first groove and the second groove.

    Abstract: A method for a transmission and reception point (TRP) for controlling cross-link interference comprises the steps of: determining a timing advance (TA) value, for measuring or eliminating cross-link interference, in a set subframe if a section in which cross-link interferences occur between the TRP and one or more adjacent TRPs is configured; and transmitting the determined TA value in the set subframe to a terminal, wherein the section in which cross-link interference occurs can correspond to a section that is configured as an uplink section for the TRP, and as a downlink transmission section for the one or more adjacent TRPs.

    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 in which a terminal performs a HARQ operation in a NoMA-based system comprises a step of receiving a downlink control information (dci) format comprising a multiple access (MA) signature field for supporting NoMA transmission; a step of receiving downlink data based on a value of the MA signature indicated by the MA signature field; and a step of transmitting an ACK/NACK signal with respect to the downlink data based on a subframe offset value, a frequency offset value, or a sequence index value, which are tied with the indicated value of the MA signature according to a predefined rule, wherein the subframe offset value comprises the subframe offset value between a reception subframe of the downlink data and a downlink HARQ feedback transmission subframe with respect to the downlink data, and wherein the frequency offset value indicates a frequency band used for transmitting the ACK/NACK signal.
