Abstract
A method is described performed by a network node for supporting cell selection of user equipments, UEs, in a wireless communication network. The wireless communication network comprises low power nodes, LPN (), and high power nodes, HPN (). The LPNs and the HPNs are arranged to transmit signals wirelessly to UEs (-). The method comprises identifying () cell range expansion, CRE, areas of a group of LPNs, which CRE areas experience interference from a group of HPNs. The method further comprises counting () the number of HPNs in the group of HPNs and the number of LPNs in the group of LPNs, and when the numerical relation between the number of LPNs and the number of HPNs fulfills a predefined criterion, triggering () connection of a UE situated in any of the identified CRE areas to the LPN of the identified CRE area in which the UE is situated, and when the numerical relation between the number of LPNs and the number of HPNs does not fulfill the predefined criterion, triggering () connection of a UE situated in any of the identified CRE areas to one of the HPNs of the group of HPNs.
