METHOD AND DEVICE FOR FEEDING BACK SPATIAL CHANNEL STATE

摘要

A method for feeding back spatial channel state and a device for feeding back spatial channel state are disclosed by the invention. The method for feeding back spatial channel state according to an embodiment of the present invention includes: determining the probability of being scheduled of the spatial channel; determining feedback information based on the probability of being scheduled of the spatial channel; and transmitting the determined feedback information; wherein more feedback information is used for the spatial channel having high probability of being scheduled than that of the spatial channel with low probability of being scheduled.
