Network node and a method therein for estimating a convergence time of interference processing in a user equipment in a radio communications network

摘要

A method performed by a network node (110) for estimating a convergence time of interference processing in a user equipment, UE (121), served by the network node (110) in a radio communications network (100) is provided. The network node has at least one Channel State Information, CSI, process configured for the UE. The network node receives, from the UE, at least one first CSI report based on signals transmitted on interference measurement resources of a first CSI process of the UE, wherein the first CSI process is in a first interference state. The network node then switches the first CSI process from the first interference state to a second interference state. After the switch, the network node receives, from the UE, at least one second CSI report based on signals transmitted on the interference measurement resources of the first CSI process of the UE, wherein the first CSI process is in the second interference state. Then, the network node estimates the convergence time of the interference processing in the UE using the received at least one first CSI report and the received at least one second CSI report. A network node (110) for estimating a convergence time of interference processing in a user equipment, a computer program and carrier are also provided.
