Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate after 4G communication systems such as LTE. A method according to an embodiment of the present invention is a communication method in a base station which communicates via filter bank-based multicarrier signals. The method may comprise the steps of: performing communication by allocating filters having non-orthogonality with respect to a first terminal positioned within a cell; selecting a filter set from among two or more filter sets having orthogonality with respect to a second terminal positioned at the edge of the cell; and performing communication by allocating, to the second terminal, at least one filter among filters included in the selected filter set.

Abstract: This disclosure relates to a 5G or pre-5G communication system to be provided for supporting higher data transfer rate following a 4G communication system such as LTE. To accomplish the objective mentioned above, a method for transmitting and receiving a signal at a terminal in the mobile communication system according to one embodiment of the present application comprises the steps of: receiving, from a base station, a reference signal generated on the basis of a first filter; determining channel information on the basis of the received reference signal; transmitting the determined channel information to the base station; receiving, from the base station, information related to a second filter determined on the basis of the channel information; and receiving, from the base station, a data signal on the basis of the second filter. According to an embodiment of the present application, it is possible to maximize the signal-to-interference-plus-noise ratio (SINR) while minimizing spectral interference in the event of multiuser connection, by using a prototype filter application method and system structure.

Abstract: A method and apparatus for transmitting symbols for use in an FBMC wireless communication system are provided. The FBMC symbol transmission method includes determining a truncation point of a first FBMC symbol overlapping a transient transmission duration based on an energy distribution characteristic of a first filter applied to the first FBMC symbol, wherein the first FMBC symbol is to be transmitted in a non-transient transmission duration, truncating the first FBMC symbol at the truncation point in the transient transmission duration, changing an energy characteristic of a second filter, filtering the first FBMC symbol using the second filter, filtering FBMC symbols positioned within the non-transient transmission duration based on a non-transient transmission duration characteristic; and transmitting the filtered FBMC symbols at a corresponding transmission timing.

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 filter bank-based channel state report and resource allocation method and an apparatus for use in a wireless communication system are provided. The channel state report method of a receiver in a filter bank-based wireless communication system includes receiving filter bank information on at least two filter banks from a transmitter, measuring a channel state of the each of at least two filter banks based on the filter bank information, and transmitting channel state information, which is generated based on the measurement result, to the transmitter.
