Patent ID: 10624076

Abstract:
A method for transmitting and receiving downlink control information in a wireless communication system supporting device-to-device communication and a device for the same are disclosed. The method for receiving downlink control information in a wireless communication system supporting D2D (Device-to-Device) communication includes: receiving, by a UE, downlink control information for D2D communication from an eNB; transmitting, by the UE to a reception UE, D2D communication control information on a PSCCH (Physical Sidelink Control Channel) based on the downlink control information; and transmitting, by the UE to the reception UE, D2D communication data on a PSSCH (Physical Sidelink Shared Channel) based on the downlink control information, wherein the downlink control information may include: a hopping flag field indicating whether frequency hopping is applicable 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 for the PSSCH in a frequency domain; a second PSSCH RA field including scheduling information for the PSSCH in a time domain; and a TPC (Transmission Power Control) field including transmission power information for the PSCCH and PSSCH.
