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.
