METHOD FOR DETERMINING TRANSMISSION POWER FOR DIRECT COMMUNICATION BETWEEN TERMINALS IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS FOR SAME

摘要

Disclosed is a method for transmitting and receiving a signal by a device to device (D2D) terminal in a wireless communication system, according to an embodiment of the present invention, the method comprising the steps of: calculating a power headroom; and reporting the power headroom to a base station, wherein, if a terminal performs an uplink transmission to the base station on a first component carrier and performs a D2D transmission on a second component carrier, the terminal, when calculating the power headroom, considers transmission power related to a minimum coverage for D2D communication.

1. A method of transmitting and receiving a signal, which is transmitted and received by a D2D (device to device) UE in a wireless communication system, comprising the steps of:
calculating a power headroom; and reporting the power headroom to an eNB, wherein if the UE performs uplink transmission to the eNB on a first component carrier and performs D2D transmission on a second component carrier, the UE considers transmit power related to minimum coverage of D2D communication for calculating the power headroom.
