[Continued on next page] (54) Title: METHODS AND ARRANGEMENTS FOR CSI REPORTING o\ i-H 0\ (57) Abstract: Some embodiments provide method in a a wireless device for reporting channel state information, CSI, for CSI process. a The CSI process corresponds to a reference signal resource and an interference measurement resource. According to the method, the wireless device obtains (810) an ad­ justment value associated with the CSI process. The wireless device estim­ ates (820) an effective channel based on one or more reference signals re­ ceived in the reference signal resource, and applies (830) the adjustment value to the estimated effective channel, thereby obtaining an adjusted effect­ ive channel. Furthermore, the wireless device determines (840) channel state information based on the adjusted effective channel, and on interference es - timated based on the interference measurement resource. Finally, the channel state information transmitted is (850) to a network node.
