    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.
