Abstract: Embodiments of the present disclosure provide a method and apparatus for transmitting a D2D discovery signal and a communication system. The method for transmitting includes: a UE selects a part of resources from a resource pool for transmitting a D2D discovery signal; the part of resources are selected in a manner of limiting number of times of transmission, or in a manner of limiting time interval, or in a manner of calculating a resource position; and transmits the D2D discovery signal by using the selected part of resources. With the embodiments of the present disclosure, malignant competitions may be avoided, resource utilization may be improved, and probabilities of undiscovery between UEs may be lowered; or detection may performed accurately, and complexity of a UE may be lowered.
