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 for signal transmission includes determining whether to perform repeated transmissions for a time length of a multiplication of L and M or more, wherein L indicates the overlapping factor of the system and M indicates a number of quadrature amplitude modulation (QAM) filter bank multi-carrier (FBMC) symbols, determining information on a type of the repeated transmissions to be performed, and transmitting FBMC symbols using a transmit power determined based on the type of the repeated transmissions. A base station includes a transceiver unit to send and receive signals, a control unit configured to determine whether to perform repeated transmissions for a time length of a multiplication of L and M or more, determine information on a type of the repeated transmissions to be performed, and transmit FBMC symbols using a transmit power determined based on the type of the repeated transmissions.

Abstract: An apparatus and method is proved that transmits and receives Reference Signals (RSs) in a wireless communication system using Multiple-Input and Multiple-Output (MIMO). A system adapted to the method is provided. The method includes: determining the number of RS transmission to two or more antennas, respectively, as the number of antennas included in respective ports, wherein each port include one or more antennas; creating transmit patterns so that they cyclically differ from each other every the number of RS transmission to transmit the created transmit patterns the number of RS transmission times; and mapping the RSs to one or more antennas according to the created, respective patterns, and transmitting the RSs in order.
