Abstract
A method and an apparatus for implementing channel measurement are disclosed in the present invention. The method includes: determining an antenna port subset, which is required to be measured, for a UE according to current state information of the user equipment UE; and informing the UE to perform channel measurement for the subset of antenna ports that is required to be measured and feed back channel state information. Through the present invention, when the state information of the UE meets a certain condition, the UE measures only the reference signals of a part of antenna ports, and feeds back channel state information for this part of antenna ports. Therefore, the overhead generated by the feedback of the UE to the channel state information is reduced.
