The present disclosure provides a scheduling assignment indicating method and device-to-device (D2D)-enabled wireless device. The method is used by D2D-enabled wireless devices communicating with each other via multiple SA periods, each of which including a SA pool and a data pool, wherein the SA pool is used for transmitting SA for assigning data resource of the data pools, the method comprising: selecting SA resources in SA pools of more SA periods to transmit SA to assign the same data resource for the D2D-enabled wireless device. The SA indicating method and D2D-enabled wireless device according to the present disclosure can increase the capacity of the SA pools, avoid SA and/or data transmission collisions, and increase the robustness of the SA transmission.
