METHOD OF DYNAMIC FEEDBACK BY CSI Russian patent published in 2018 - IPC H04L5/00 H04W16/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to communication. Described are systems and methods for providing of a feedback in the form of information (CSI) on the channel state in a cellular communication network. In some embodiments, the cellular communication base station disables channel interpolation and/or filtering between subframes for CSI-RS estimates by subframes in a wireless communication device and receives one or more CSI reports from a wireless communication device, which are generated by a wireless communication device with disconnected channel interpolation and/or filtering between subframes for CSI-RS estimates by subframes in response to the fact that the base station disables channel interpolation and/or filtering between the subframes in the wireless communication device for CSI-RS estimates by subframes.

EFFECT: thus, improving the feedback by CSI, especially in embodiments of the invention in which the base station transmits the beam-forming resource(s) of CSI-RS and reuses the same CSI-RS resource(s) for different beams over time.
