Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). According to various embodiments, an apparatus of a user equipment (UE) in a wireless environment comprises at least one transceiver; and at least one processor operably coupled to the at least one transceiver. The at least one transceiver is configured to receive a reference signal configuration comprising information for indicating whether a reference signal of a transmission and reception point (TRP) is transmitted through beam sweeping from the TRP, and receive the reference signal from the TRP based on the received reference signal configuration.

Abstract: The present disclosure relates to a pre-fifth generation (5G) or 5G communication system to be provided for supporting higher data rates beyond fourth generation (4G) communication system such as long term evolution (LTE).A synchronization signal transmission/reception method for use in a device-to-device (D2D) communication system is provided. A method of transmitting a synchronization signal for D2D communication in an asynchronous network, in which a first terminal located in a first cell controls synchronization with a second terminal located outside of the first cell, includes transmitting, at the first cell, a system information block (SIB) including resource allocation information of the first cell and at least one neighboring cell, determining whether the first terminal is in a first mode and whether the first terminal is scheduled to perform one of a D2D communication and a D2D discovery; determining, when the first terminal is in the first mode, whether the first terminal is required to transmit a D2D synchronization signal (D2DSS); and transmitting, when the first terminal is required to transmit the D2DSS, scheduling information including a transmission time point and transmission reference timing information to the first terminal.

Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). Disclosed is a method for operating a BS for supporting mixed numerology in a wireless communication system. The method includes: generating a first signal for a first group and a second signal for a second group according to different configurations; and transmitting the first signal through a first channel allocated for the first group and the second signal through a second channel allocated for the second group.

Abstract: The present invention relates to a 5G or pre-5G communication system which is to be provided to support high data throughput beyond a 4G communication system such as LTE. The communication method for a terminal in a wireless communication system supporting carrier aggregation according to the present invention comprises the steps of: confirming data transmission between different carriers is carried out on the basis of cellular and device-to-device (D2D) communication; reducing the transmission power for a D2D communication-based data transmission to a configured value; and, if no cellular communication-based data transmission occurs during a set time, then restoring the reduced transmission power for the D2D communication-based data transmission.
