摘要： A base station and terminal use methods of obtaining synchronization and system information in a wireless communication system. An operation of a base station includes generating a synchronization signal to be transmitted through a Synchronization Channel (SCH), generating a broadcast signal to be transmitted through a Broadcast Channel (BCH), and transmitting repetitively the SCH and the BCH by performing beamforming on the channels with different transmission beams.

摘要： Disclosed is a 5G or pre-5G communication system to be provided so as to support a data transmission rate higher than that of a 4G communication system, such as LTE. Disclosed is a communication method of a base station using a channel state information reference signal (CSI-RS) in a mobile communication system, the method comprising the steps of: receiving a sounding reference signal (SRS) from a terminal; selecting a precoding matrix by using the received SRS; transmitting a CSI-RS by using the selected precoding matrix; receiving a CSI report from the terminal, and determining a transmission parameter on the basis of the CSI report; and transmitting data to the terminal by applying the determined transmission parameter thereto, wherein the CSI-RS is aperiodically transmitted.
