    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 includes configuring a first sounding channel to be an uplink sounding slot. The uplink sounding slot has at least one OFDM symbol in an uplink sub-frame in order to carry UL-SRSs corresponding to at least one transmit beam of a first set of transmit beams in a first sounding channel set of sub-bands. The first sounding channel set of sub-bands includes sub-bands that cover a first data bandwidth. The method includes transmitting, to an MS, a first UL sounding configuration message that sets a sounding sub-band bitmap value to a maximum specifiable value and indicates UL-SRS placement in the first sounding channel set of sub-bands. The method includes, receiving through the first sounding channel set of sub-bands from the MS, the UL-SRSs corresponding to at least the one transmit beam of the first set of transmit beams for channel estimation over the first data bandwidth.
