Abstract: The present invention defines a method for controlling uplink transmission power of a terminal in a communication system which is operated by combining heterogeneous systems. Specifically, the present invention defines a method for selectively applying a power control command in order to control uplink power of a terminal in a communication system which is operated by combining an LTE/LTE-A system with a system which applies a new radio access technology, and a method for differently operating power control units depending on whether beam sweeping is applied or not.

Abstract: Provided is a method of sending and receiving signals for a user equipment (UE) in a mobile communication system. The method may include: receiving discovery signal configuration information; scanning a discovery signal resource region determined based on the discovery signal configuration information; transmitting a discovery signal at a resource of the discovery signal resource region selected based on the scanning result; and rescanning the discovery signal resource region on the basis of at least one of the discovery signal configuration information and the scanning result. There are provided a method and apparatus for sending and receiving a discovery signal for D2D communication in a wireless communication system. A UE is allocated discovery signal transmission resources via signaling from the ENB and periodically rescans the discovery signal transmission resources. Thereby, it is possible to send and receive discovery signals in a more efficient manner.
