WIRELESS DEVICE, NETWORK NODE AND METHODS FOR REPORTING CHANNEL STATE INFORMATION (CSI) IN RADIO COMMUNICATIONS NETWORK Russian patent published in 2018 - IPC H04W72/12 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to means for providing information on the status of a CSI channel in a radio data transmission network. Method performed by the wireless device for determining Channel State Information, CSI, estimates to be transmitted in a CSI report for at least one CSI process configured for the wireless device to a network node in a radio communications network, method comprises an order of actions: receiving a message comprising an indication to discard existing CSI estimates corresponding to a determined period of time and determining CSI estimates, which should be used in the CSI report to the network node, in accordance with the accepted indicator, in which the network node causes the wireless device to transmit CSI estimates corresponding to the CSI measurement results obtained from a single point in time.

EFFECT: technical result is to improve the reporting of information on the state of the CSI channel in the radio data transmission network.
