D2D RESOURCE ALLOCATION METHOD, AND DATA TRANSMISSION METHOD AND DEVICE

摘要

Disclosed are a D2D resource allocation method, and data transmission method and device, the D2D resource allocation method comprising: determining a D2D resource configuration corresponding to the quality of service (QoS) level of a D2D service; and transmitting to a user equipment (UE) the information of the D2D resource configuration corresponding to the service quality level of the D2D service. The D2D data transmission method comprises: according to the received information of the D2D resource configuration corresponding to the service quality level of the D2D service, selecting a transmission resource for the D2D service to be transmitted; and transmitting the data of the D2D service over the selected transmission resource. The D2D service transmission requirement is considered in allocating and selecting D2D resources, thus further improving the system D2D resource allocation efficiency without affecting the D2D service transmission requirement.
