摘要： 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.

摘要： 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.

摘要： The present disclosure provides in some embodiments a resource scheduling method and a resource scheduling device for a vehicle infrastructure cooperative communication system, and a node of the vehicle infrastructure cooperative communication system. According to the present disclosure, a movement trend between nodes is determined in accordance with node position information, so as to spatially multiplex time-frequency resources and prevent the frequent adjustment of time-frequency resources, thereby to reduce signaling overhead for allocating the time-frequency resources and improve utilization of the time-frequency resources.

摘要： 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.

摘要： Disclosed are a resource selection method and apparatus under multiple carriers, a computer device and a storage medium. The resource selection method comprises: determining at least one candidate carrier according to a resource occupancy exclusion result on each carrier; setting a resource on the candidate carrier to be available, performing exclusion according to a sensing result and obtaining a set of available resources; selecting a transmission resource from the set of available resources, and setting a semi-persistent scheduling counter for resource scheduling. The present application provides a resource selection solution reducing half-duplex influence as far as possible, and reducing the impact due to loss of receiving opportunities and the number of skip subframes, and also avoids the problem of too severe power allocation caused by simultaneous transmission with multiple service packets.

摘要： 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.

Disclosed are a time slot state update method and device, which are used to improve the time flexibility during update of the time slot state. In the present invention, a communications node determines an update period of a time slot state table, the update period comprising x continuous time slots and x being an integer not less than 1 and not greater than the total of the time slots comprised in one frame; and the communications node updating the time slot state table after the update period ends. It can be seen that, the solution can improve the time flexibility during update of the time slot state.
