An apparatus, method and system for measuring interference for direct device-to-device communications in a communication system. In one embodiment, an apparatus includes a processor and memory including computer program code. The memory and the computer program code are configured, with the processor, to cause the apparatus to monitor an interference transmission from device-to-device (D2D) user equipment participating in cellular communications employing a communication resource; and format a message for reporting the interference levels observed during the interference transmission. In another embodiment, a memory and the computer program code are configured, with the processor, to cause the apparatus to monitor a precoded RS interference transmission from a node B station participating in cellular communications including D2D devices employing a communication resource; and format a message for reporting the RS levels observed during the interference transmission.
