Abstract

Embodiments of the present invention provide a resource scheduling method, device and system. The embodiments of the present invention relate to the technical field of communication, and are used to solve the problem of resource scheduling in D2D communication. The method includes the first node sending first control signaling to the second node, where the first control signaling includes second control signaling transmission resource information and data transmission resource information. The second node receives the first control signaling sent by the first node, and uses the second control signaling transmission resource to send the second control signaling to the third node, and uses the data transmission resource to send data to the third node. The resource scheduling method, device, and system provided by the embodiments of the present invention can be applied to data transmission equipment that requires high delay performance.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a resource scheduling method, device, and system. Background technique [0002] With the development of wireless communication technologies, services with super-high transmission rates (for example, high-definition video) are produced, and the load of wireless communication networks is getting heavier and heavier. Device to Device (hereinafter referred to as: D2D) communication is direct communication between terminals and does not require the base station to forward the transmission data. It can not only share the data transmission load of the base station, but also increase the data transmission rate. [0003] In order to improve spectrum utilization and maximize the use of radio frequency capabilities of existing terminals, in mobile communication systems such as Long Term Evolution (LTE for short), D2D communication links usually reuse spec...
