Abstract: The present specification provides a method for transmitting a signal in a wireless communication system. More specifically, the method performed by a transmission terminal comprises the steps of: generating at least one bit into a complex symbol by using a modulation scheme; mapping the complex symbol to subcarriers each having an even index or subcarriers each having an odd index among subcarriers of at least one configured resource block; performing IFFT on the subcarriers to which the complex symbol is mapped, in order to generate a time-continuous signal; performing a DC bias on the time-continuous signal; and transmitting the DC biased signal.

Abstract: An improved layered decoding method for a low density parity check (LDPC) code and a device therefor are disclosed. Disclosed is the layered decoding method for an LDPC code, capable of determining whether decoding is successful by performing a syndrome check on each check node at every variable node update. In addition, the syndrome check can be performed by using reduced variable nodes, thereby reducing decoding power consumption and decoding time consumption.

Abstract: Provided are a method and a device for transmitting uplink data by using a non-orthogonal code multiple access scheme in a wireless communication system. Particularly, a terminal receives control information from a base station. The terminal selects a terminal-specific codeword or receives allocation information of the terminal-specific codeword on the basis of the control information. The terminal transmits uplink data by using the terminal-specific codeword. The terminal-specific codeword is determined as a codeword having a value with a low peak-to-average power ratio (PAPR), when the terminal is located on the outside of a cell. The terminal-specific codeword is determined as a codeword having a value with a high PAPR, when the terminal is located in the center of the cell.

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 for transmitting feedback information by a terminal may comprise the steps of: measuring a channel; multiplying a first matrix associated with the measured channel by a transformation matrix, so as to obtain a second matrix and transmitting the obtained second matrix to a base station in a bit format. In addition, the transformation matrix may be determined on the basis of an angle offset satisfying a predetermined condition.
