Abstract: The present invention provides a signal determining method and an apparatus, so as to resolve a problem, in a conventional positioning method, that a signal receiving device cannot accurately determine whether a received signal is an aggregated reference signal, and consequently, positioning fails due to a relatively large error of location information obtained by means of positioning. The method is as follows: A signal receiving device may estimate, according to a TAE between at least two subcarriers used by a signal sending device to transmit a reference signal and a reference signal sent by the signal sending device on each subcarrier, an aggregated reference signal that is sent by the signal sending device and that is obtained after carrier aggregation. After receiving a signal, the signal receiving device determines whether the signal is an aggregated reference signal sent by the signal sending device.

Abstract: Embodiments of the present disclosure provide a positioning method based on a time difference of arrival, user equipment, and a network device. The method includes: calculating, by user equipment, a first time difference of arrival RSTD1 based on positioning signals sent by a first base station and a second base station at a same moment; calculating a second time difference of arrival RSTD2 based on known location information of the user equipment; calculating a time alignment error TAE based on the RSTD1 and the RSTD2; and performing, based on the TAE, positioning based on a time difference of arrival TDOA. According to this method, the TAE caused by the base stations is subtracted during positioning calculation. In other words, the time alignment error caused by the base stations is eliminated. Therefore, accuracy of TDOA-based positioning can be ensured.
