A method and an apparatus for transmitting information in device-to-device D2D communication are provided, where the method includes: determining, by a first user equipment, in a communication resource for D2D communication, a target resource used to bear a reference signal RS, where the target resource is according to characteristic information used in selecting the target resource, and the characteristic information used in selecting the target resource includes at least one of the following two items: characteristic information used to uniquely identify the first user equipment, and characteristic information used to uniquely identify a second user equipment that performs D2D communication with the first user equipment; and transmitting, by the first user equipment, the RS to the second user equipment by using the target resource. A target resource used to bear a reference signal is determined according to characteristic information of a user equipment that performs device-to-device communication, which can implement dynamic configuration of a resource, so that transmission of a reference signal between each terminal pair can still be ensured even in a case in which the number of terminal pairs that perform device-to-device communication is relatively large. |
