摘要： 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.

摘要： 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.

摘要： A method and an apparatus for detecting inter-cell interference in a mobile communication system are provided. A base station receives a reference signal (RS) from a terminal, generate one or more interference candidate RSs, calculate a cross correlation of the one or more interference candidate RSs and the received RS, estimate at least one of a size of a Resource Block (RB) an offset of the RB, a group index (U), and a cyclic shift (CS) by using a preset number of interference candidate RSs in an order of the large cross correlation. The base station further removes an interference signal or performs a direct reduction by using at least one of the estimated RB size, the RB offset, the timing offset, and the group index (U). According to the present disclosure, it is beneficial to mitigate or cancel inter-cell interference problem on an uplink transmission without any assistance of neighbor base stations and/or adjacent cells in a wireless communication system.
