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: Embodiments of the present application are for use in solving the problem of high probability of collisions occurring among existing node devices. Disclosed are a method and device for information submission and resource allocation in the V2X system. The resource allocation method comprises: a network side device assigns a subframe resource to a node device just accessing a cell and notifies the node device just accessing the cell of the assigned subframe resource; for node devices already accessing the cell, the network side device determines colliding node devices, reassigns subframe resources to the colliding node devices, and respectively notifies the colliding node devices of the reassigned subframe resources. Because employed is a solution in which resources are scheduled collectively by a network side device for node devices accessing a cell, in addition to ensuring time-division multiplexing of resources among a node device and other node devices having needs for communication in the surrounding, thus increasing system capacity, timely and effective solution of resource collisions among colliding node devices is also allowed, thus increasing the performance of communication among system node devices.
