    Abstract: Embodiments of the present invention disclose a method and an apparatus for positioning a user equipment. The method includes receiving positioning measurement information sent by a base station. The positioning configuration information includes a sum of a difference between receiving time and sending time on the UE and a difference between receiving time and sending time on the base station. A round trip time between the intermediate node that sends the CRS and the UE is calculated according to the positing in formation. A position of the UE is determined using position coordinates of the intermediate node that sends the CRS and the round trip time.

    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.
