Embodiments of the present disclosure provide a floor positioning method and system, and a device, and relate to the communications field. The method includes: receiving a reference signal sent by at least one access point in an indoor environment in which UE is located; determining measurement information based on a polarization direction of the at least one received reference signal, where the measurement information includes at least one access point identifier and a proportion-related value of a vertical polarization direction relative to the polarization direction of the reference signal corresponding to the at least one access point identifier; sending the measurement information to a positioning server; and receiving location information of the UE sent by the positioning server, where the location information of the UE includes a floor location of the UE, and the floor location of the UE is determined based on the measurement information.

Floor positioning method and system, and device

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.
