Abstract:
1. A method performed in a wireless node which communicates with a network node, for reporting channel state information, CSI, for at least two CSI processes, each of the at least two CSI processes corresponding to a reference signal resource and an interference measurement resource, wherein the reference signal resource includes a first set of resource elements in which one or more reference signals corresponding to a desired signal are received, and wherein the interference measurement resource includes a second set of resource elements in which one or more signals assumed to be interfering with the desired signal are received, the method comprising for each of the at least two CSI processes: obtaining an adjustment value associated with the CSI process; determining an adjusted effective channel based on the adjustment value and the one or more reference signals received in the reference signal resource; determining channel state information for the CSI process based on the adjusted effective channel, and on interference estimated based on the interference measurement resource; and transmitting the channel state information to the network node.
