Abstract: Base station (BS) and mobile station (MS) methods and apparatus are provided. The BS configures an uplink sounding channel made up of at least one OFDM symbol in an uplink slot. The BS signals to the MS use and location of different configurations of the uplink sounding channel via a system configuration broadcast message. The uplink sounding channel comprises OFDM symbols where one or more of a subcarrier spacing and a sampling frequency is different from that of OFDM symbol used for data transmission. Each OFDM symbol comprises a sounding reference symbol corresponding to at least one transmit beam and is received by at least one receive beam to form at least one transmit-receive beam pair. The at least one transmit-receive beam pair for UL-SRS in different OFDM symbols are different. The sounding channel configuration is based on information received from neighboring BSs via inter-BS coordination over a pre-defined interface.
