The present invention relates to the transmission and the reception of filter bank multi-carrier (FBMC) symbols in a wireless communication system, a method for operating a transmitting end comprises the step of: generating a first symbol in which sample values of a front end are shifted to a rear end; generating a second symbol in which sample values of a rear end are shifted to a front end; and transmitting a plurality of symbols comprising the first symbol and the second symbol on a time axis in an overlapping manner. ## Claims ### Claim 1 A method for operating of a transmitting end in a wireless communication system, the method comprising: generating a first symbol in which sample values of a front end are shifted to a rear end; generating a second symbol in which sample values of a rear end are shifted to a front end; and transmitting a plurality of symbols comprising the first symbol and the second symbol on a time axis in an overlapping manner. ### Claim 2 (depends on 1) The method of claim 1, wherein generating the first symbol comprises generating an FBMC symbol using a frequency domain filter to which a phase shift value corresponding to a number of the sample values is applied or a time domain filter which is circularly shifted as much as the number of the sample values. ### Claim 3 (depends on 1) The method of claim 1, further comprising transmitting, to a receiving end, information for determining a shift pattern of the sample values, wherein the information comprises at least one of an amount of data to be transmitted, information on whether an adjacent channel is used or not, and a degree of interference by the adjacent channel. ### Claim 4 (depends on 3) The method of claim 3, further comprising receiving information indicating the shift pattern of the sample values from the receiving end, wherein the shift pattern is defined through at least one of a cyclic shift value and an offset value. ### Claim 5 (depends on 4) The method of claim 4, wherein the cyclic shift value decreases as the degree of interference by the adjacent channel increases, and the offset value decreases as the amount of data to be transmitted increases. ### Claim 6 (depends on 1) The method of claim 1, wherein the number of the sample values shifted in the first symbol is less than half of a total number of symbols of the first symbol. ### Claim 7 An apparatus for a transmitting end in a wireless communication system, the apparatus comprising: a transceiver; at least one processor operatively coupled with the transceiver, wherein the at least one processor is configured to control to: generate a first symbol in which sample values of a front end are shifted to a rear end, and generate a second symbol in which sample values of a rear end are shifted to a front end; and transmit a plurality of symbols comprising the first symbol and the second symbol on a time axis in an overlapping manner. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the at least one processor is configured to control to generate an FBMC symbol using a frequency domain filter to which a phase shift value corresponding to a number of the sample values is applied or a time domain filter which is circularly shifted as much as the number of the sample values. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein the at least one processor is configured to transmit, to a receiving end, information for determining a shift pattern of the sample values, wherein the information comprises at least one of an amount of data to be transmitted, information on whether an adjacent channel is used or not, and a degree of interference by the adjacent channel. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the at least one processor is further configured to control to receive information indicating the shift pattern of the sample values from the receiving end, wherein the shift pattern is defined through at least one of a cyclic shift value and an offset value. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the cyclic shift value decreases as the degree of interference by the adjacent channel increases, and the offset value decreases as the amount of data to be transmitted increases. ### Claim 12 (depends on 7) The apparatus of claim 7, wherein the number of the sample values shifted in the first symbol is less than half of a total number of symbols of the first symbol. ### Claim 13 An apparatus for a receiving end in a wireless communication system, the apparatus comprising: a transceiver; and at least one processor operatively coupled with the transceiver, wherein the at least one processor is configured to control to: receive a signal in which a plurality of symbols overlap one another on a time axis; detect a first symbol in which sample values of a front end are shifted to a rear end from among the plurality of symbols; and detect a second symbol in which sample values of a rear end are shifted to a front end from among the plurality of symbols. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the at least one processor is configured to control to detect an FBMC symbol using a frequency domain filter to which a phase shift value corresponding to a number of the sample values is applied or a time domain filter which is circularly shifted as much as the number of the sample values. ### Claim 15 (depends on 13) The apparatus of claim 13, wherein the at least one processor is configured to receive, to a transmitting end, information for determining a shift pattern of the sample values, wherein the information comprises at least one of an amount of data to be transmitted, information on whether an adjacent channel is used or not, and a degree of interference by the adjacent channel. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the at least one processor is further configured to control to transmit information indicating the shift pattern of the sample values from the receiving end, wherein the shift pattern is defined through at least one of a cyclic shift value and an offset value. ### Claim 17 (depends on 16) The apparatus of claim 16, wherein the cyclic shift value decreases as the degree of interference by the adjacent channel increases, and the offset value decreases as the amount of data to be transmitted increases. ### Claim 18 (depends on 13) The apparatus of claim 13, wherein the number of the sample values shifted in the first symbol is less than half of a total number of symbols of the first symbol.
