Abstract: The present invention provides a method for notifying Multicast Broadcast Single Frequency Network (MBSFN) subframe configuration, which comprises the following steps: a first node sends its MBSFN subframe configuration, via an X2 interface, to a second node with which the first node is connected; the first node receives the MBSFN subframe configuration of the second node as a feedback. According to the invention, a serving cell can obtain the MBSFN subframe configurations of the neighboring cells and/or RNs, so that rational utilization of resources is achieved according to the configurations. Therefore, interference between cells is reduced, and system capacity and efficiency are improved.

Abstract: Embodiments of the present disclosure provide a method and a device for identifying a synchronization priority, including: determining a synchronization priority of a node according a connection relationship between the node and a Global Navigation Satellite System (GNSS) and a relative relationship between the node and a coverage scope of an eNB; configuring a synchronization sequence and an in coverage flag of the node according to the synchronization priority of the node. Combination of the synchronization sequence and the in coverage flag of the node is used to identify the synchronization priority of the node.

Abstract: Disclosed are a method and apparatus for sending and broadcasting resource information, the method comprising: determining a resource used by a second-type node and a resource used by a first-type node, and determining the first-type node receiving a resource coordination message, wherein the first-type node is a node located within a base station signal coverage range, and the second-type node is a node located outside of the base station signal coverage range; and sending the resource coordination message to the determined first-type node, and instructing the first-type node to broadcast the contents of the resource coordination message, wherein the resource coordination message carries resource information about the first-type node and the second-type node. By means of the present application, resource continuity in the process of a node moving on a network coverage edge is guaranteed, resource collision is reduced, and the utilization rate of system resources is improved.

Abstract: The present disclosure provides a method and a device for scheduling resources in an internet of vehicles system, to centrally allocate timeslot resources in the internet of vehicles system at a network side. The method includes: receiving, by a scheduling device, information of a geographical area reported by a first node and corresponding to the first node; and determining, by the scheduling device, timeslot resources capable of being scheduled within the geographical area reported by the first node, and allocating a timeslot resource from the determined timeslot resources for the first node. Each cell is divided into geographical areas, and an identical timeslot resource can be shared by non-adjacent geographical areas in an identical cell, and/or non-adjacent geographical areas in different cells. By centralized scheduling of timeslot resources, it is able to ensure communication between nodes within a predetermined range, thereby preventing impact of timeslot resources used by the nodes.
