Information relating to Orthogonal Frequency Division Multiplexing (OFDM) parameter sets supported by a Base Station (BS), from among a plurality of OFDM parameter sets, is transmitted to at least one Mobile Station (MS), from the BS, using a default OFDM parameter set. The BS selects at least one OFDM parameter set for the at least one MS, from among the OFDM parameter sets supported by the BS, based on one of a channel state and a mobility of the at least one MS. The BS performs data communication with the at least one MS through the at least one selected OFDM parameter set. Each of the plurality of OFDM parameter sets comprises parameter values representing a Cyclic Prefix (CP) length, a subcarrier spacing, and at least one of an Inverse Fast Fourier Transform (IFFT) size and Fast Fourier Transform (FFT) size. The default OFDM parameter set is determined based on subcarrier spacings of the plurality of OFDM parameter sets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication method and apparatus in a wireless communication system supporting multiple OFDM parameter sets","description":"Communication methods and apparatuses in a wireless communication system are provided.
