Abstract: [Problem] Provided is an interference protection mechanism for communications using a transmit beam in a sidelink.
[Solution] A terminal device capable of communication using any communication method classified as vehicle-to-x (V2X) includes: an acquisition unit that acquires first information relating to allocation of a resource pool that can be used by a plurality of terminal devices using the communication method and second information relating to transmit power which is associated with a beam ID of one or a plurality of transmit beams which the terminal devices use in communication using the communication method; a parameter determination unit that determines parameters relating to the transmit beams on the basis of the first information and the second information; and a transmission processing unit that performs packet transmission processing using the communication method on the basis of the determined parameters.

Abstract: [Overview][Problem to be Solved] To provide a communication apparatus that allows a transmitting station to accurately determine whether or not a receiving station actually has interference.[Solution] There is provided a communication apparatus including a communication control unit that controls a communication process in a cellular system. The communication control unit sets a plurality of reception beams on the basis of information of a direction, measures received power for each of the reception beams, and reports a result of the measurement to a base station. The information of the direction is set from the base station.
