    摘要： A method performed by a wireless device (121, 122) 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 (121, 122) to a network node (110) in a radio communications network (100) is provided. The wireless device (121, 122) receives a message comprising an indication to discard existing CSI estimates and/or an indication to use CSI estimates corresponding to a determined period of time. In response to said message, the wireless device (121, 122) determines CSI estimates to be used in the CSI report to the network node (110) according to the received indication. A wireless device (121, 122) is also described.
    Furthermore, a network node (110) and method therein for controlling CSI estimates transmitted by one or more wireless devices (121, 122) in CSI reports of at least one CSI process configured for the one or more wireless devices (121, 122) to the network node (110) in a radio communications network (100) are also provided.
