摘要： Embodiments of the present invention relate to the field of wireless communications. 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.

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： 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： 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.
