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.

Abstract: A positioning signal processing method includes receiving positioning reference signal (PRS) configuration information from a positioning device. A PRS is received as a PRS resource set. Each PRS resource set includes one or more PRSs. One access network device corresponds to one or more PRS resource sets. The positioning signal processing method further includes determining PRS time domain information based on the PRS configuration information. The time domain information includes a periodicity (P) of the PRS and a symbol length of the PRS in the P. The positioning signal processing method further includes receiving a plurality of PRSs based on the PRS time domain information.
