Abstract
This invention provides a mobility cell measurement method and apparatus for a mobile communications system like as LTE-A. The method includes: performing inter-carrier synchronous transmission of a synchronous signal on at least two Component Carriers (CCs); sending information regarding one or more CCs among the at least two CCs that is capable of performing Carrier Aggregation (CA) with a carrier of a serving cell to a user equipment through higher-level signaling; and sending joint mobility measurement information to the user equipment of the serving cell, wherein the user equipment determines a CC for performing joint mobility measurement according to the information regarding the one or more CCs and the joint mobility measurement information and performs the joint mobility measurement on the determined CC. This increases the speed of the mobility measurement and reduces the power consumption of the user equipment.
