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: The present invention provides a carrier selection method for positioning measurement, which is applied to positioning measurement in a carrier aggregation scenario. The method includes: obtaining information about carriers supported by each base station participating in positioning; obtaining carriers supported by a terminal and quality information of each carrier; and selecting an optimal carrier supported by each base station from the carriers supported by the terminal, so that the terminal performs positioning measurement according to the optimal carrier. The present invention also provides a positioning measurement method, a positioning processing apparatus, and a terminal. By using the above solution, positioning measurement of terminal is implemented in a carrier aggregation scenario. Moreover, because an optimal carrier of each base station is selected for the terminal to perform positioning measurement, the accuracy of positioning measurement is improved, and thereby the accuracy of positioning is improved.
