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: This application relates to network management technologies, and disclosed are a method and device for scheduling slot resources. The method is: upon reception of each new data packet delivered by a high level, a first node maintaining corresponding sending remaining time according to a delay requirement of the new data packet; performing slot resource determination on each extracted data packet, starting from the new data packet, in ascending order of the sending remaining time; when it is determined that the number of data packets to be sent in the sending remaining time corresponding to any data packet is greater than the number of slots currently used by the first node, applying for new slot resources. Therefore, when learning that the slot resources cannot meet the delay requirement of the data packet to be sent, the first node can apply for new slot resources in time, so as to solve the slot resource scheduling problem under the time division resource allocation mechanism based on FI interaction, meet the low-delay requirement on message exchange in telematics, and ensure timely message transmission, thereby effectively ensuring the performance of the telematics.

Abstract: A method and device for resource reservation are provided. The resource reservation method includes: receiving scheduling assignment information transmitted by first UE, where the scheduling assignment information includes information about time-frequency resource that the first UE needs to reserve; determining the quantity of reservations for the time-frequency resource by the first UE according to the scheduling assignment information; if new scheduling assignment information about the time-frequency resource transmitted by the first UE has been received before the quantity of reservations becomes invalid, re-determining reservation information for the time-frequency resource according to the new scheduling assignment information; and if no new scheduling assignment information about the time-frequency resource transmitted by the first UE has been received before the quantity of reservations becomes invalid, taking the time-frequency resource as an idle resource.

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.
