    Abstract: A method for determining an uplink (UL) channel quality by a base station (BS) includes obtaining a coverage class (CC) value of a user equipment (UE), receiving a random access (RA) signal from the UE, determining an UL channel quality of a band in which the RA signal is transmitted, based on the CC value and the RA signal, and generating UL resource allocation information based on the UL channel quality and transmitting the UL resource allocation information to the UE. The BS includes a transceiver configured to obtain a CC value of a UE and to receive a RA signal from the UE, and a controller configured to determine an UL channel quality of a band in which the RA signal is transmitted, based on the CC value and the RA signal. A UE includes determines a CC value of the UE based on a DL signal.

    Abstract: A transmitter, a receiver, and a method for measuring a radio channel based on reference signals transmitted through a predetermined number of OFDM symbols by using multiple antennas in an ultra-high frequency band, and controlling a beam width of analog beams formed by transmission multiple antennas based on the measurement result. The transmitter uniquely distributes a predetermined number of analog beams among the analog beams formed by the array antenna in correspondence to each of the predetermined number of OFDM symbols, and repeatedly allocates the predetermined number of analog beams distributed for each of the predetermined number of OFDM symbols by targeting the subcarriers within the corresponding OFDM symbol. The receiver receives a channel measurement instruction message, measures a channel state based on reference signals transmitted through the analog beams allocated for respective subcarriers, and feeds the channel state measurement result back to the transmitter.

    Abstract: One or more embodiments provide a method for controlling array antenna device in a base station (BS) in a communication system. The method includes determining whether to perform a calibration operation for BSs while operating in one of a normal mode and an interference control mode. The method also includes transiting from the one of the normal mode and the interference control mode to a calibration mode based on the determining result of whether to perform the calibration operation for the BSs. A reference antenna among antennas included in the array antenna device is used in all of the normal mode, the interference control mode, and the calibration mode.
