INFORMATION FEEDBACK METHOD AND NETWORK NODE

The present invention relates to the field of communications technologies, and in particular, to an information feedback method and a network node, which are used for resolving a technical problem in the prior art that a base station cannot acquire a separate signal. Two information feedback modes are set in embodiments of the present invention. When it is determined that a current information feedback mode is a separate feedback mode, a first type of network node may determine that a feedback object is a valid signal and/or a noise signal, so that a measurement result of the valid signal and/or a measurement result of the noise signal may be separately fed back, thereby resolving the problem that exists in the prior art.
