Abstract: Provided is a distributed scheduling method and apparatus for resource allocation for Device-to-Device (D2D) communication. The method includes sending, by a Mobile Station (MS) including data to transmit, a first resource reservation message through at least one first slot among a plurality of slots constituting a resource reservation unit in a resource reservation channel; and when a second resource reservation message sent by another MS is not sensed in a slot with a higher priority than the first slot in the resource reservation unit, transmitting the data through a transmission resource unit corresponding to the resource reservation unit in a data transmission channel. The resource reservation channel corresponds to the transmission resource unit, and the plurality of slots has mutually cyclic priorities.
