A floor positioning method, applied to a user equipment, UE, comprising: receiving a reference signal sent by at least one access point in an indoor environment in which the UE is located; determining measurement information based on a polarization direction of the at least one received reference signal, wherein the measurement information comprises 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, wherein the location information of the UE comprises a floor location of the UE, and the floor location of the UE is determined based on the measurement information, wherein the determining of the floor location of the UE based on the measurement information includes: determining a target access point identifier from the at least one access point identifier based on the proportion-related value of the vertical polarization direction relative to the polarization direction of the reference signal corresponding to the at least one access point identifier; querying a preset correspondence between an access point identifier and a floor based on the target access point identifier; and determining a floor corresponding to the target access point identifier as the floor location of the UE. receiving a reference signal sent by at least one access point in an indoor environment in which the UE is located; determining measurement information based on a polarization direction of the at least one received reference signal, wherein the measurement information comprises 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, wherein the location information of the UE comprises a floor location of the UE, and the floor location of the UE is determined based on the measurement information, wherein the determining of the floor location of the UE based on the measurement information includes: determining a target access point identifier from the at least one access point identifier based on the proportion-related value of the vertical polarization direction relative to the polarization direction of the reference signal corresponding to the at least one access point identifier; querying a preset correspondence between an access point identifier and a floor based on the target access point identifier; and determining a floor corresponding to the target access point identifier as the floor location of the UE. determining a target access point identifier from the at least one access point identifier based on the proportion-related value of the vertical polarization direction relative to the polarization direction of the reference signal corresponding to the at least one access point identifier; querying a preset correspondence between an access point identifier and a floor based on the target access point identifier; and determining a floor corresponding to the target access point identifier as the floor location of the UE.
