Method for supporting D2D communication to which MIMO technology is applied and device therefor
Disclosed is a method for supporting device-to-device (D2D) communication to which multiple-input and multiple-output (MIMO) technology is applied in a wireless communication system. The method for supporting D2D communication includes receiving, from a transmission end, a resource configuration associated with transmission and reception of a first reference signal and D2D data of a D2D resource pool in an uplink resource; transmitting, to the transmission end, the first reference signal related to at least one first antenna port of the D2D terminal through an uplink resource according to the resource configuration; receiving, through the uplink resource, D2D data and a second reference signal from at least one second antenna port among a plurality of second antenna ports of the transmission end determined based on the first reference signal; and decoding the received D2D data based on a precoding applied to the second reference signal.
