Problems solved by technology

[0012] The existing ALOHA mechanism does not provide an effective solution to the above problems, but simply considers that the multi-slot resources of a node operate independently, and the operation of each time slot is processed as a single time slot. However, this method is not flexible , Effectively process and coordinate multi-slot resources, often there will be some application errors

Embodiment Construction

[0046] Under the MS-ALOHA mechanism in the vehicular communication system, when a node (hereinafter referred to as the first node) occupies multiple time slots at the same time, in order to facilitate resource management, in the embodiment of the present invention, no matter how many timeslots the first node simultaneously occupies For time slots, the first node maintains only one time slot state vector (table) to process receiving and sending messages. This scheme is also called a single-table scheme. For the convenience of description, assuming that there are N time slots in one frame in the system, a possible time slot state vector (table) is as follows Figure 1A shown.

[0047] In the time slot state vector (table), the time slot state information corresponding to each time slot is stored as a time slot information unit, denoted as Unit, which stores various types of information required in the receiving and sending process.

[0048] On the other hand, in the embodiment o...

Abstract

The invention relates to the field of communication, and discloses a single table processing method and device for multi-time slot resources. The method is as follows: for each time slot included in the frame period, the first node uniformly maintains the time slot state vector that stores the time slot state information of each time slot, and sends information to other time slots used by itself in each frame period The node sends FI, and receives FI sent by other nodes on the time slot not used by itself in each frame period, and according to the received FI, the corresponding time slot state of each time slot in the time slot state vector maintained locally In this way, it meets the needs of multi-slot resource operation of various business types of the Internet of Vehicles, can effectively process and coordinate multi-slot resources, and uses a slot state vector (table) to process node multi-slot resources. The storage capacity is small, and the processing load is uniform, which will not cause excessive operating load to the system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for single-table processing of multi-slot resources. Background technique [0002] With the development of in-vehicle communication systems and the gradual maturity of mobile ad hoc network technology, in order to realize real-time, dynamic and intelligent management of vehicles, DSRC (Dedicated Short Range Communications, Dedicated Short Range Communications) protocol for Internet of Vehicles has been specially developed in the world. . DSRC organically connects vehicles with vehicles, vehicles and roadside information collection equipment through two-way transmission of information, and supports point-to-point and point-to-multipoint communication. [0003] The mobile slotted ALOHA (Mobile Slotted Aloha, MS-ALOHA) mechanism is a DSRC MAC (Medium Access Control; Media Access Control) layer access and resource allocation mechanism based on time-sharing. Resource all...
