摘要： The present invention provides a method and apparatus for indicating downlink channel measurement and a method and apparatus for performing channel measurement. The method for indicating downlink channel measurement comprises: receiving information on interferes of a user equipment; generating, based on downlink subframe configuration information, a downlink channel measurement indication for each of possible combinations of the interferers, wherein the channel measurement indication is adapted to indicate a subframe group to be measured by a user equipment; and sending the downlink channel measurement indication to the user equipment so as to indicate the user equipment to perform corresponding downlink channel measurement. According to embodiments of the present invention, the subframe groups that are required to be measured by the user equipment may be determined with respect to possible combinations of interferers corresponding to different levels of interference. Thus, the user equipment may perform channel measurement for respective subframe groups. Therefore, the channel quality as determined in such way will be more accurate and reliable and better match the actual channel condition. Moreover, it also provides a possibility for the serving node to perform the scheduling more accurately and effectively.
