Title: D2D COMMUNICATION METHOD, USER EQUIPMENT, AND BASE STATION
Abstract:
Disclosed are a D2D communication method, a user equipment and a base station, for use in implementing resource allocation of a D2D distributed network and implementing efficient utilization of a channel. The method in an embodiment of the present invention comprises: a UE acquires a data transmission request of a D2D distributed network; the UE acquires time-frequency resources for performing channel measurement; then the UE measures a channel where in the time-frequency resources are located to determine whether the channel is idle; and if the channel is idle, the UE establishes a D2D connection by means of the channel. The present invention provides a resource allocation process in a D2D distributed network, and resource allocation of a D2D multi-hop data transmission scenario on the basis of a D2D distributed network can be implemented.
