    Abstract: Embodiments of the present invention disclose a timing value adjustment method and apparatus, which relate to the communications field and reduce a probability that power of a terminal exceeds a limit. A specific solution is that: an absolute timing difference of a timing advance group TAG pair is obtained according to an absolute value of a difference between transmit timing values or receive timing values of the two TAGs in the TAG pair, where the TAG pair is formed by any two TAGs in a TAG set; and it is determined that the absolute timing difference of the TAG pair meets a predetermined condition, and first signaling is sent to a network device, where the first signaling includes identifiers of the two TAGs in the TAG pair. The present invention is used in a timing value adjustment process.

    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.

    Abstract: Embodiments of the present invention provide a method and a device for positioning a user equipment in a handover process. The method mainly includes: receiving, by a target base station of the user equipment in the handover process, positioning measurement related information of the user equipment transmitted from a source base station of the user equipment; and performing, by the target base station, a positioning measurement for the user equipment according to the positioning measurement related information after the user equipment has accessed the target base station successfully. Embodiments of the present invention enables the target base station to perform positioning measurement for the user equipment immediately after the UE has successfully accesses the target base station, and eliminates the need for a positioning server to retrigger a user equipment positioning process, thus reduces the signaling cost caused by retriggering the user equipment positioning process.
