  • Patent number: 9838845
    Abstract: Provided is a method for positioning a user equipment (UE). In the method, a positioning server determines that a UE is in a coordinated multi-point transmission (CoMP) state; requests a plurality of serving base stations in a CoMP set of the UE and the UE to measure a parameter related to positioning of the UE; receives the parameter related to the positioning of the UE from the plurality of serving base stations and the UE; and determines a location of the UE according to the received parameter.

  • Patent number: 9451534
    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.
