Abstract
A method performed by a network node for locating a User Equipment (UE) is provided. The network node, the at least one portable network node and UE operate in a wireless communication network. The network node configures () the at least one portable network node to broadcast reference signals. The broadcasted reference signals trigger the UE to subsequently measure and report the quality of the respective reference signals to the network node. The network node then receives () subsequent measurement reports from the UE. Each measurement report comprises a current quality value of the reference signals sent by the respective at least one portable network node. The network node manages the respective at least one portable network node to approach the position of the UE by: Meanwhile analyzing the subsequent measurement reports, commanding () each of the at least one portable network node to move in a direction that is decided based on the analysis of its corresponding subsequent measurement reports one by one upon receiving them. The moving direction is to be performed such that quality values of its corresponding reference signals in subsequent measurement reports are increasing.
