Abstract

Embodiments of the present invention provide a method and an apparatus for allocating a device-to-device (D2D) communications resource. The method for allocating a device-to-device (D2D) communications resource in the present invention comprises: a first network device receiving device-to-device (D2D) communications capabilities sent by user equipments in coverage; the first network device sending, according to the communications capabilities, a resource identification to each of the user equipments in the coverage of the first network device in a D2D group, the D2D group comprising at least two user equipments; and the first network device sending a resource allocation message, the resource allocation message carrying D2D communication resource allocation information corresponding to the resource identification. In the embodiments of the present invention, by allocating a same resource identification to user equipments in a D2D communications group, and using a same resource allocation message to carry resource allocation information corresponding to the resource identification, signaling overheads are reduced and the allocation efficiency is improved in a process of allocating resources used in a discovery stage and resources used in a communication stage to the user equipments in the D2D group.
