The present invention relates to the transmission of a filter bank multi-carrier (FBMC) symbol in a wireless communication system, and a method for operating a transmission terminal comprises the steps of: transmitting a first FBMC symbol generated by applying filters to subcarriers according to a first pattern; and transmitting a second FBMC symbol generated by applying the filters to the subcarriers according to a second pattern. In addition, the present invention also comprises examples different from the above mentioned example. ## Claims ### Claim 1 A method for operating a transmitting node in a wireless communication system, the method comprising: receiving, from a receiving node, control information indicating a set of filter interleaving patterns including a first filter pattern and a second filter pattern; transmitting, to the receiving node, a first filter bank multi-carrier (FBMC) symbol generated by applying filters to subcarriers based on the first filter pattern; and transmitting, to the receiving node, a second FBMC symbol generated by applying the filters to the subcarriers based on the second filter pattern. ### Claim 2 (depends on 1) The method of claim 1, further comprising: wherein the control information further comprises at least one index indicating a combination of filter set and filter patterns. ### Claim 3 (depends on 1) The method of claim 1, further comprising: transmitting, to the receiving node, control information indicating whether a guard carrier is set according to filter interleaving. ### Claim 4 (depends on 1) The method of claim 1, further comprising: wherein the control information further comprises control information indicating whether a guard carrier is set according to filter interleaving performed. ### Claim 5 (depends on 1) The method of claim 1, further comprising: wherein the control information further comprises at least one of control information indicating the second filter pattern and control information indicating a set of patterns comprising the first filter pattern and the second filter pattern. ### Claim 6 (depends on 1) The method of claim 1, wherein, in the first FBMC symbol and the second FBMC symbol, a filter applied to at least one carrier is a different filter. ### Claim 7 (depends on 1) The method of claim 1, wherein the first FBMC symbol comprises an initial transmit packet, and the second FBMC symbol comprises a retransmit packet. ### Claim 8 (depends on 1) The method of claim 1, wherein the first FBMC symbol and the second FBMC symbol comprise at least one of data symbols space-time coded and the same data symbols for repetition transmission. ### Claim 9 A method for operating a receiving node in a wireless communication system, the method comprising: transmitting, to a transmitting node, control information indicating a set of filter interleaving patterns including a first filter pattern and a second filter pattern; receiving, from the transmitting node, a first filter bank multi-carrier (FBMC) symbol generated by applying filters to subcarriers based on the first filter pattern; and receiving, from the transmitting node, a second FBMC symbol generated by applying the filters to the subcarriers based on the second filter pattern. ### Claim 10 (depends on 9) The method of claim 9, further comprising: wherein the control information further comprises at least one index indicating a combination of filter set and filter patterns. ### Claim 11 (depends on 9) The method of claim 9, further comprising: receiving, from the transmitting node, control information indicating whether a guard carrier is set according to filter interleaving. ### Claim 12 (depends on 9) The method of claim 9, further comprising: wherein the control information further comprises control information indicating whether a guard carrier is set according to filter interleaving performed. ### Claim 13 (depends on 9) The method of claim 9, further comprising: wherein the control information further comprises at least one of control information indicating the second filter pattern and control information indicating a set of patterns comprising the first filter pattern and the second filter pattern. ### Claim 14 (depends on 9) The method of claim 9, wherein, in the first FBMC symbol and the second FBMC symbol, a filter applied to at least one carrier is a different filter. ### Claim 15 (depends on 9) The method of claim 9, wherein the first FBMC symbol comprises an initial transmit packet, and the second FBMC symbol comprises a retransmit packet. ### Claim 16 (depends on 9) The method of claim 9, wherein the first FBMC symbol and the second FBMC symbol comprise at least one of data symbols space-time coded and the same data symbols for repetition transmission. ### Claim 17 An apparatus for operating a transmitting node in a wireless communication system, the apparatus comprising: at least one processor;
