1. A method of a transmitting equipment for acquiring sidelink channel state information (CSI), the method comprising:
transmitting, to a receiving equipment, information indicating to report the sidelink CSI through a sidelink control information (SCI) format;
transmitting, to the receiving equipment, sidelink CSI reference signal (RS) in association with the information indicating to report the sidelink CSI; and
acquiring the sidelink CSI based on sidelink CSI reporting from the receiving equipment,
wherein the sidelink CSI RS is transmitted within a resource assigned for a physical sidelink shared channel (PSSCH) transmission,
wherein the sidelink CSI RS is transmitted to the receiving equipment only if enabling information of the sidelink CSI reporting is received by the transmitting equipment,
wherein the SCI format includes a specific value in a field for the information indicating to report the sidelink CSI,
wherein a specific higher layer parameter is used for acquiring the sidelink CSI,
wherein the sidelink CSI RS is transmitted based on configuration information by a higher layer signaling, and
wherein the configuration information relates to a first parameter indicating a first orthogonal frequency division multiplexing (OFDM) symbol in a physical resource block (PRB used for the sidelink CSI RS and a second parameter indicating a number of antenna ports and a frequency domain allocation for the sidelink CSI RS.
