Abstract: The present invention discloses a method, an apparatus, and a system for user equipment positioning. The method includes, during positioning measurement of the UE, when the UE needs to be handed over from a source node to a target node, receiving, by the target node, user identification information of the UE; sending, by the target node, an indication of not notifying a positioning server to an MME; after the UE is handed over to the target node, performing, by the target node, positioning measurement on the UE according to the user identification information, and reporting obtained positioning measurement data and the user identification information to the positioning server.

Abstract: An interference cancellation method, data sending method, apparatus, user equipment and base station in a Long Term Evolution system are disclosed. The interference cancellation method includes: obtaining downlink cell-specific power ratio information of a specific cell; performing channel estimation based on a downlink cell-specific reference signal (CRS) of the specific cell, to obtain a channel estimation matrix of a specific physical channel, signal, or message of the specific cell; compensating the channel estimation matrix by using the downlink cell-specific power ratio information; and canceling, in an original signal that is received from a target cell and is interfered by the specific cell, interference caused by the specific cell in a received signal from a specific physical channel, signal, or message. A technical problem in the prior art that a user equipment cannot effectively cancel interference because power transmission strength of a strong interfering cell cannot be correctly estimated is solved.
