Abstract:
A method performed by a wireless device (121, 122) for determining Channel State Information, CSI, estimates to be transmitted in a CSI report 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 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.
A network node (110) and method therein for controlling CSI estimates transmitted by one or more wireless devices (121, 122) in CSI reports to the network node (110) in a radio communications network (100) are also provided.
