    Abstract: A method in which a base station transmits pilot signals in a multiple-antenna communication system is provided. The base station includes some of the plurality of pilot signals distinguished by at least one of time domain symbols, subcarriers, and orthogonal codes in a first set to which a first random number is applied. The base station includes the remaining pilot signals, excluding the pilot signals that are included in the first set, in a second set that uses the same resources as used by the first set and to which a second random number different from the first random number is applied. The base station transmits at least one of the pilot signals that belong to the first set and the second set.

    Abstract: A method and apparatus for scheduling a beam in a mobile communication system are provided. A terminal receives signals through a plurality of switching beam directions, and receives a plurality of beams that are transmitted while performing beam switching in a transmission time interval (TTI) unit by a base station. The terminal selects a signal having largest intensity among received signals, and transmits an uplink scheduling request signal in a beam direction corresponding to the selected signal.

    Abstract: Disclosed are a method for generating a random access signal of a machine type communication (MTC) device using a narrow bandwidth, and an MTC device. The method generates a random access signal by allocating a position in a frequency domain of a random access signal dedicated to the MTC device, that is, a position of a frequency for transmission of a random access preamble, to a center position of a base station system bandwidth, or by shifting a center frequency of the MTC device to a position of a random access frequency allocated for a legacy LTE terminal by a base station.
