Abstract: Communication methods and apparatuses in a wireless communication system are provided. 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

Abstract: A method for distributed scheduling in a transmission node of a wireless communication system is provided. The method includes transmitting a power signal through a first tone in a Transmission (Tx) block including tones mapped with a plurality of link identifiers, receiving a power signal from a reception node through a second tone indicating that data transmission is possible in a first Reception (Rx) block including tones mapped with a plurality of link identifiers, and receiving a power signal from the reception node through a third tone including information about a link identifier that is permissible to the reception node, in a second Rx block including tones mapped with a plurality of link identifiers.

Abstract: A method for operating a Base Station (BS) in a wireless communication system is provided. The method comprises of receiving at least one request set for at least one neighboring cell, from at least one Mobile Station (MS), updating the at least one request set based at least in part on a serving band of each MS, and transmitting the updated at least one request set to the at least one neighboring cell, wherein the request set comprises a band and a Precoding Matrix Index (PMI) for making a use restriction or recommendation request to a neighboring cell.
