Abstract

Method and an apparatus for configuring a coordinated multi-point measurement set. An embodiment of the present invention provides a method at a neighboring base station side (26) for configuring a coordinated multi-point measurement set for a user equipment UE (22), and the method includes: a neighboring base station (26) of the UE (22) receiving (40), from a serving base station (24) of the UE (22), configuration information about an uplink signal sent by the UE (22); the neighboring base station (26) detecting (42), according to the configuration information, the uplink signal sent by the UE; and the neighboring base station reporting (44), to the serving base station (24), a transmission port TP receiving the uplink signal and strength of the TP receiving the uplink signal. The present invention is based on the latest development demands of LTE/LTE-A protocols, and is applicable to various scenes.
