CONTROL INFORMATION TRANSMISSION METHOD IN D2D COMMUNICATION, APPARATUS AND COMMUNICATION SYSTEM

摘要

Embodiments of the present invention provide a control information transmission method in D2D communication, an apparatus and a communication system, wherein the transmission method comprises: configuring a control channel used for the D2D communication, wherein the control channel comprises control information used for the D2D communication and a reference signal sequence or a preamble sequence that indicates a D2D communication resource location; and sending the control information used for the D2D communication and the reference signal sequence or the preamble sequence through the control channel. Through the embodiments of the present invention, demodulation complexity of a receiver in the D2D communication can be decreased, a cache required during demodulation can be reduced, and a resource waste due to resource collision can be diminished.
