A method for determining an angle of arrival at a communication device is described. The method comprises performing a message exchange between the communication device and a further communication device. The message exchange comprises receiving at least one first message associated with a first frequency at the communication device by means of a first antenna and a second antenna and receiving at least one second message associated with a second frequency at the communication device by means of the first antenna and the second antenna. The method further comprises determining the angle of arrival defined by an orientation of the communication device and a transmission direction of the message exchange, wherein the angle of arrival is determined based on the received first message and the received second message. Furthermore, a corresponding communication device is described.
