Abstract

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.

Description

technical field [0001] Embodiments herein relate to estimating a convergence time for interference handling in a user equipment in a radio communication network. In particular, embodiments herein relate to a network node and methods therein for estimating a convergence time for interference handling in a user equipment in a radio communication network. Background technique [0002] In a typical radio communication network, wireless terminals, also called mobile stations, terminals and / or user equipment UE, communicate via a radio access network RAN ​​with one or more core networks. A radio access network covers a geographical area divided into cell areas, where each cell area is served by a base station such as a radio base station RBS or a network node, which in some networks may also be eg called a "NodeB" or "eNodeB". A cell is a geographical area where radio coverage is provided by a radio base station at a base station site or antenna site without collocation of antenn...
