摘要： The present invention provides a method for removing a self-interference in a wireless access system supporting a full duplex radio (FDR) scheme, and devices for supporting the same. A method by which a transmission end removes self-interference in a wireless access system supporting an FDR scheme, according to one embodiment of the present invention, can comprise the steps of: transmitting two transmission signals by using two transmission antennas; receiving two reception signals by using two reception antennas; estimating a self-interference channel; and removing interference signals by considering the self-interference channel estimated from the reception signals. Here, the interference signals are the transmission signals which are inputted to the two reception antennas, the transmission signals and the reception signals are simultaneously transmitted and received through a resource region comprising the same time and frequency, and the two transmission antennas and the two reception antennas can be disposed on the transmission end in a diamond shape.

摘要： Disclosed herein are a method and apparatus for transmitting/receiving an uplink signal. A user equipment receives information indicating a data transmission code rate for uplink data. The user equipment channel-codes the uplink data using a channel code corresponding to a channel code rate. The channel code rate is determined among a plurality of predefined channel code rates based on the data transmission code rate. The user equipment transmits the channel coded uplink data.

摘要： A method for removing a self-interference signal by a device supporting an FDR mode can further comprise the steps of: transmitting a signal to a counterpart node in a predetermined time interval; generating, in an RF stage of the device, a residual self-interference signal after removal of an analog self-interference signal with respect to the signal and then storing same; and receiving from the counterpart node an ACK/NACK signal with respect to the transmission of the signal; and determining whether or not the stored residual self-interference signal is to be used thereafter on the basis of the ACK/NACK signal.

摘要： Provided are a method and an apparatus for allocating, by a first OFDM system and a second OFDM system, frequency resources, which are multiplexed in a frequency region, in a wireless communication system. Specifically, the sizes of the frequency resources of the first OFDM system, which corresponds to an existing OFDM, and the second OFDM system, which corresponds to a UF-OFDM, are determined. Adjacent subcarriers are instructed to allocate any one of a guard carrier and a subcarrier to which null data is allocated, while performing frequency resource allocation between the first and second OFDM systems in accordance with the determined sizes of the frequency resources. The information regarding the frequency resource allocation, which comprises information indicative of either the guard carrier or the subcarrier, is transmitted.

摘要： Provided is a transmission device for transmitting data in a wireless communication based on DFT-spread OFDM. Specifically, provided is a transmission device which outputs a first sub-band and a second sub-band by performing DFT on an input symbol with a tail part and a head part in which at least one 0 has been inserted by a DFT block controlled by a processor, outputs a signal by performing IDFT on the first sub-band which has been mapped by a first IDFT block, allows the signal to be filtered by a first band pass filter, outputs a signal by performing IDFT on the second sub-band which has been mapped by a second IDFT block, and allows the signal to be filtered by a second band pass filter.
