METHOD FOR TRANSMITTING/RECEIVING DOWNLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM SUPPORTING DEVICE-TO-DEVICE COMMUNICATION AND APPARATUS THEREFOR

摘要

Disclosed are a method for transmitting/receiving downlink control information in a wireless communication system supporting a device-to-device (D2D) communication and an apparatus for the same. More particularly, a method for receiving downlink control information in a wireless communication system supporting a device-to-device (D2D) communication may include the steps of: receiving downlink control information for a D2D communication from a base station by a terminal; transmitting D2D communication control information to a receiving terminal through a physical sidelink control channel (PSCCH) on the basis of the downlink control information by the terminal; and transmitting D2D communication data to the receiving terminal through a physical sidelink shared channel (PSSCH) on the basis of the downlink control information by the terminal, wherein the downlink control information may include: a hopping flag field indicating whether a frequency hopping is applied or not when transmitting the D2D communication control information and the D2D communication data; a PSCCH resource allocation (RA) field including scheduling information for the PSCCH; a first PSSCH RA field including scheduling information in a frequency domain for the PSSCH; a second PSSCH RA field including scheduling information in a time domain for the PSSCH; and a transmission power control (TPC) field having transmission power information of the PSCCH and the PSSCH.
