Example Embodiment

[0026] Briefly, an exemplary embodiment of a network node and a method therein is provided for controlling uplink power control in an area including at least one macro radio base station RBS and at least one low power RBS. In short, a cluster of low-power RBS and macro RBS is created based on the measurement reports collected from the UE; the level of path loss is identified, and the interference level in the low-power RBS is determined. Based on this, the uplink power control setting is selected for low power RBS.

[0027] Will now refer to figure 2 To describe an exemplary embodiment of a method for controlling uplink power control in an area including at least one macro RBS and at least one low-power RBS in a network node in a wireless communication network, figure 2 It is a flowchart of a method for controlling uplink power control in a network node in a wireless communication network according to an exemplary embodiment.

[0028] figure 2 The illustrated method includes col...

Abstract

A Network Node and a method therein for controlling uplink power control are provided. The method comprises collecting (210) measurement reports from UEs. The method comprises creating(220) clusters of low power RBS(s) and macro RBS(s), wherein each cluster comprises one low power RBS and at least one macro RBS; and identifying (230) the macro RBS with the lowest pathloss for those UEs connected to the low power RBS and the level of the pathloss. The method comprises determining (240) an interference level in the low power RBS caused by UEs connected to the macro RBS for those UEs connected to the macro RBS. Further, the method comprises selecting (250) uplink power control setting for the low power RBS based on the size of the pathloss associated with the identified macro RBS and the interference level in the low power RBS caused by UEs being connected to the macro RBS.

Description

technical field [0001] The present disclosure relates to radio resource control, and in particular to controlling uplink power control for user equipment served by a low power radio base station. Background technique [0002] A radio access network of a wireless or cellular communication network comprises a plurality of radio base stations RBS distributed in an area. The area can be a district, a city, a country or several countries. Typically, each RBS is associated with a coverage area commonly referred to as a cell. [0003] In a wireless or cellular communication network, users with user equipment UE may move around, causing the traffic load in each cell or RBS to vary over time. As a result, some RBSs may experience very heavy traffic load at certain times. [0004] The geographic area of ​​a wireless or cellular communication network may vary from cell to cell and may also be within a cell. For example, in a city, there may be buildings of different heights and siz...
