| 摘要 |
Embodiments of the present invention provide a method and apparatus for timing advance adjustment in multi-point cooperation transmission, wherein the method comprises receiving, at one or more reception points, an uplink reference signal from a user equipment; selecting, based on signal quality of the uplink reference signal, one of the one or more reception points as a reference point for the user equipment to adjust timing advance; and indicating a selected reference point to the user equipment. With the method and apparatus in the embodiments of the present invention, a user equipment may be provided with a suitable reception point as a reference point so that the user equipment can efficiently adjust the timing advance based on the time situation of receiving signals from the reference point so as to overcome inter- symbol-interference at the reception point, improve the receiving efficiency of the reception point, and thereby to improve the whole performance of a multi-point cooperation transmission system. |
