Abstract: 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.

Abstract: Embodiments of the present invention disclose a method which including: receiving a locating reference signal sent by a locating transmitter; performing time domain related processing on the locating reference signal and a synchronization reference signal sequence to obtain a related spectrum value of a multipath signal component corresponding to a delay value; detecting a channel parameter used when the locating reference signal is received, and generating, according to the channel parameter and a function that progressively decreases with the delay value, a related spectrum threshold that progressively decreases with the delay value; and traversing the delay value in ascending order of the delay value, searching for a first traversed delay value whose related spectrum value of a multipath signal component corresponding to the delay value is greater than a related spectrum threshold corresponding to the delay value, and using the found delay value as TOA for outputting.

Abstract: Embodiments of the present invention provide a positioning information processing method and apparatus. The method includes: receiving, by a test terminal, a cell-specific reference signal sent by a base station, and obtaining an original cell-specific reference signal; obtaining, by the test terminal, a multipath characteristic quantity according to the received cell-specific reference signal and the original cell-specific reference signal; and sending, by the test terminal to a server, RSRP, timing information, and a multipath characteristic quantity that are corresponding to each test site, so that the server implements a positioning service.
