    Abstract: A millimeter radio wave communication system. In a method for operating a base station (BS) in an analog/digital mixed BF system, an analog BF direction is determined. A digital BE precoder is determined for the determined analog BE direction. Digital BF precoding is performed using the digital BE precoder with respect to the determined analog BF direction. A DownLink Reference Signal (DL RS) is transmitted in the analog BF direction on which the digital BF precoding has been performed.

    Abstract: An apparatus implements methods for random access in a wireless communication system using beamforming. A Subscriber Station (SS) measures a best downlink transmission beam among downlink transmission beams transmitted from a Base Station (BS), and transmits Random Access Channel (RACH) information, which includes indication information indicating the best downlink transmission beam, to the BS. The BS receives RACH information which includes indication information indicating a best downlink transmission beam among downlink transmission beams, and detects an RACH sequence and the best downlink transmission beam from the received RACH information.

    Abstract: The present invention relates not only to a fourth-generation (4G) communication system, such as long-term evolution (LTE), but also to a fifth-generation (5G) or pre-5G communication system to be provided to support a higher data transfer rate. The present invention provides a method for a first device in a communication system supporting a device-to-device (D2D) scheme, the method comprising the steps of: when existence of a second D2D device, of which the location information needs to be detected, has been detected, transmitting a discovery request message which requests activation of at least one of an urgent discovery operation and a location measurement operation; receiving a discovery response message to the discovery request message from at least one device including the second device; and transmitting, to the second device, information related to execution of the location measurement operation.

    Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data rates than a 4th generation (4G) communication system such as long term evolution (LTE). A method for positioning a user equipment (UE) in a wireless communication system includes receiving a reference signal (RS) in a first bandwidth from each of a plurality of anchor nodes scheduled for RS transmission by a network server, determining whether a path overlap has occurred between the UE and the anchor nodes based on symmetry of channel impulse responses of the received RSs, transmitting a bandwidth extension request message to the network server, upon occurrence of a path overlap, receiving an RS in a second bandwidth larger than the first bandwidth from each of the plurality of anchor nodes in response to the transmission of the bandwidth extension request message, and generating information required to position the UE, using the RSs received in the second bandwidth.
