Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for transmitting signal based on a filter bank multi-carrier (FBMC) modulation, a method for receiving signal based on the FBMC modulation, and a corresponding transmitting device and receiving device are provided. The method includes preprocessing determined symbols in a data block comprising at least one symbol, modulating the preprocessed data block with the FBMC modulation, truncating the modulated data block to remove a part or all of tailing data therefrom, and transmitting the truncated modulated data block, from which the part or all of tailing data has been removed, wherein the determined symbols are affected by the truncating of the modulated data block.

First claim

What is claimed is:

1 . A method for operating a transmitting device in a wireless communication system based on filter bank multi-carrier (FBMC) modulation, the method comprising:
preprocessing determined symbols in a data block comprising at least one symbol; modulating the data block with the FBMC modulation; truncating the modulated data block to remove a part or all of tailing data from the modulated data block; and transmitting the modulated data block, from which the part or all of tailing data is removed; wherein the determined symbols are affected by the truncating of the modulated data block.

2 . The method of claim 1 , wherein the preprocessing of the determined symbols comprises:
pre-coding the determined symbols.

3 . The method of claim 2 , wherein a pre-coding matrix used by the pre-coding of the determined symbols is determined according to filter parameters used in the FBMC modulating and parameters used in the truncating of the modulated data block.

4 . The method of claim 3 , wherein the parameters used in the truncating of the modulated data block comprise a determined truncation length.

5 . The method of claim 1 , wherein the preprocessing of the determined symbols comprises:
allocating reference signals required in the data block onto the determined symbols.

6 . The method of claim 1 , wherein the preprocessing of the determined symbols comprises:
allocating data included in un-determined symbols in an initial transmitting data block onto the determined symbols.

7 . The method of claim 1 , wherein the truncating of the modulated data block comprises at least one of:
setting a part or all of the tailing data into zero; and windowing a part or all of the tailing data.

8 . A method for operating a receiving device in a wireless communication system based on a filter bank multi-carrier (FBMC) modulation, the method comprising:
receiving at least one symbol in a data block according to a determined truncation length; and demodulating each of the symbols based on FBMC mode.

9 . The method of claim 8 , wherein the receiving of the at least one symbol comprises:
receiving an un-truncated part of the symbols upon transmitting if a determined symbol affected by the truncating of the modulated data block is received.

10 . The method of claim 9 , wherein the demodulating of each of the symbols comprises:
padding, for the determined symbols affected by truncating, zero to the un-truncated part of the symbols according to the determined truncation length, so as to obtain symbols with an original length of the symbols; and demodulating the symbols with original symbol length based on the FBMC.

11 . A transmitting device comprising:
a preprocessing unit configured to preprocess determined symbols in a data block comprising at least one symbol; a modulating unit configured to modulate the preprocessed data block with the filter bank multi-carrier modulation; a truncation unit configured to truncate the modulated data block to remove a part or all of tailing data from the modulated data block; and a transmitting unit configured to transmit the modulated data block, from which the part or all of tailing data is removed; wherein the determined symbols are affected by the truncating of the modulated data block.

12 . The device of claim 11 , wherein the preprocessing unit is configured to pre-code the determined signal.

13 . The device of claim 12 , wherein a pre-coding matrix used in the pre-coding of the determined symbols is determined according to filter parameters used in the FBMC modulating and parameters used in the truncating of the modulated data block.

14 . The device of claim 13 , wherein the parameters used in the truncating the modulated data block comprise a determined truncation length.

15 . The device of claim 11 , wherein the preprocessing unit is configured to allocate reference signals required in the data block onto the determined symbols.

16 . The device of claim 11 , wherein the preprocessing unit is configured to allocate data included in un-determined symbols in an initial transmitting data block onto the determined symbols.

17 . The device of claim 11 , wherein the truncation unit is configured to perform at least one operation of:
setting a part or all of the tailing data into zero; and windowing a part or all of the tailing data.

18 . A receiving device comprising:
a receiving unit configured to receive at least one symbol in a data block according to a determined truncation length; and a demodulating unit configured to demodulate each of the symbols based on filter bank multi-carrier demodulation mode.

19 . The device of claim 18 , wherein the receiving unit is configured to receive an un-truncated part of the symbols upon transmitting if a determined symbol affected by the truncating of the modulated data block is received.

20 . The device of claim 19 , wherein the demodulating unit is configured to pad, for the determined symbols affected by truncating, zero to the un-truncated part of the symbols according to the determined truncation length, so as to obtain symbols with an original length of the symbols; and demodulate the symbols with original symbol length based on the FBMC.
