According to an aspect, a communication device includes a communicator configured to perform communication with a base station and a plurality of access points having narrower communication ranges than the base station, a first acquirer configured to acquire vehicle information from equipment mounted in a vehicle, a second acquirer configured to acquire information about communication quality for each of the plurality of access points, a third acquirer configured to acquire a communication requirement for each piece of the vehicle information acquired by the first acquirer, and a selector configured to select an access point that transmits the vehicle information acquired by the first acquirer on the basis of the information about the communication quality acquired by the second acquirer and the communication requirement acquired by the third acquirer.

The disclosed technology provides a system and method for allocating resource blocks to a mobile device based on a traffic priority of traffic between the network and the mobile device. Traffic priority can be determined based on quality of service (QOS) identifiers or network slice identifiers. The highest priority users are allocated inner resource blocks with the lowest allowed maximum power reduction (MPR), the lowest priority users are allocated edge resource blocks with the highest allowed MPR, and the intermediate priority users are allocated outer resource blocks.

Various other aspects are contemplated.

The application data is transmitted via a radio link between a radio device Q and the wireless communication network. The application data are provided by one or more applications. A node of the wireless communication network provide control information, which is provided to at least one of the applications. The control information controls providing of the application data by the at least one application to the radio link.
