The present invention provides an unlicensed spectrum access and carrier aggregation method, device, electronic equipment and storage medium for cellular Internet of Vehicles. The method includes: detecting unlicensed channels in the current cell, receiving detection results sent by a plurality of first IoV terminals, screening and obtaining a plurality of target unlicensed channels, and determining a user group of each target unlicensed channel, and Each target unlicensed channel is aggregated to the original channel of each first IoV terminal in its corresponding user group, and each first IoV terminal in the user subgroup of each target unlicensed channel is The utility size on the time-frequency resources of each target unlicensed channel is obtained, and the time-frequency resource allocation strategy of each target unlicensed channel is obtained. Through the method provided by the invention, the unlicensed channel can be aggregated to the original channel of the cellular-controlled vehicle user, thereby increasing the number of cellular-controlled vehicle users that the network can carry and reducing the interference to VANET users.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for unlicensed spectrum access and carrier aggregation of cellular Internet of Vehicles. Background technique [0002] VANET, vehicle ad hoc network, refers to an ad hoc vehicle network formed by using unlicensed frequency bands for inter-vehicle communication. Therefore, vehicle users that originally existed on unlicensed frequency bands are called VANET users. VANET uses the IEEE802.11p protocol to build a vehicle communication network. In this way, the vehicle users exclusively occupy the unlicensed channel, that is, the same unlicensed channel can only realize the communication of one user at the same time. [0003] In related technologies, the trade-off between increasing communication capacity and fairness of VANET users has not been fully considered, and the time-frequency resource allocation scheme for cellular-controlled vehicle users ...
