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 packet transmission method and apparatus for use in a wireless communication system and, in particular, for transmitting packets in a filter bank-based multicarrier wireless communication system. The packet transmission method for use in a wireless communication system based on Filter Bank-based Multi-Carrier (FBMC) includes generating an Offset Quadrature Amplitude Modulation (OQAM) symbol by extracting a transmission data period from data blocks obtained by repeating a transmission data as many times as an overlapping factor, performing Inverse Fast Fourier Transform (IFFT) on the OQAM symbol, shifting, when the overlapping factor is an even number, the IFFT-ed symbol cyclically, filtering the cyclically shifted symbol with a shortened compensation filter, and transmitting the filtered symbol in an overlapped OQAM signal.
