The disclosure relates to methods and devices for Channel State Information, CSI, reporting. More particularly, the disclosure pertains to a wireless device filtering CSI for a dynamic channel and to the wireless device reporting filtering information defining the CSI filtering to a network node and to the network node using the reported filtering information. This disclosure proposes method performed in a second wireless node (20) that is configured to transmit data to a first wireless node (10) over a dynamic wireless channel. The method comprises receiving (S11), from the first wireless node (10), filter information defining a filter that is used in the first wireless node, for filtering Channel State Information, CSI, describing the dynamic wireless channel, transmitting (S12a) data to the first wireless node over the dynamic wireless channel, and receiving (S12b), from the first wireless node, CSI corresponding to the transmission, wherein the CSI is filtered with the filter. According to the disclosure the transmission (S12a) of data to the first wireless node and/or the reception (S12b) of CSI from the first wireless node, is based on the received filter information. |
