    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.
