Abstract: Embodiments of the disclosure provide a method and device for positioning a communication device. According to embodiments of the present disclosure, the communication device may determine, without phase information of the signals, a direction of other communication device based on an association between strength levels of signals received from the other communication device and angles at which the signals are received for better accuracy. According to embodiments of the present disclosure, the communication device may determine the direction of the other communication device without phase information of the received signals based on MUSIC algorithm. According to the embodiments of the present disclosure, the method may also be implemented in a multipath scenario.
