1. A method, comprising:
- acquiring, by a system comprising a processor, information associated with a pilot channel resource used to send at least one directional pilot signal associated with a directional device to device (D2D) communication, wherein the directional D2D communication refers to D2D communication using directional transmission over a D2D communication link, the directional transmission refers to transmission of a radio frequency signal in a first specific direction, and the at least one directional pilot signal refers to at least one pilot signal transmitting in a second specific direction; and
transmitting a data signal associated with the directional D2D communication at least according to a received state of the at least one directional pilot signal on the pilot channel resource,wherein a direction associated with the directional D2D communication is determined by one party of both parties of communication according to a position of the other party, or determined from two or more candidate directions according to communication performances and interference conditions of the two or more candidate directions.

Abstract
Device to device (D2D) communication is provided. A method comprises: acquiring information associated with a pilot channel resource used to send at least one directional pilot signal associated with directional D2D communication; and transmitting a data signal associated with the directional D2D communication at least according to a received state of the pilot signal on the pilot channel resource. Accordingly, a data signal associated with directional D2D communication can be transmitted more effectively according to a directional pilot signal related to the directional D2D communication.
