Abstract: A transmission and reception method and apparatus for reducing a PAPR in an orthogonal frequency division multiplexing (OFDM) system are provided. A transmission method includes performing constellation rotation with respect to L input data symbols, performing L-point DFT spreading and circular extension on the constellation-rotated L data symbols to be K symbols, performing frequency domain (FD) windowing processing by multiplying the K circular-extended data symbols by a circular filter coefficient, and transmitting the processed data symbols.

Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system, which is to be provided for supporting a higher data transmission rate after the 4th-generation (4G) communication system, such as long term evolution (LTE). The present invention provides a method for receiving a signal in a multi-carrier system, the method comprising the steps of: performing, with respect to an input signal, a waveform pre-processing operation on the basis of at least one of an equalizing operation and a filtering operation; checking whether the waveform pre-processed signal is a Gaussian proximity signal; and performing soft-de-mapping with respect to the waveform pre-processed signal on the basis of a result of the checking.

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 a long term evolution (LTE). An operating method of a base station (BS) in a communication system supporting a time division multiplexing (TDD) scheme is provided. The operating method includes transmitting, to a user equipment (UE) which uses a second radio access technology (RAT) different from a first RAT used by other BS different from the BS, information related to downlink (DL) and uplink (UL) timing of the other BS and margin information for synchronizing DL and UL timing of the first RAT with DL and UL timing of the second RAT, wherein the information related to the DL and UL timing of the other BS is received from the other BS, or predicted by the BS.
