Abstract

Method and arrangement in a wireless network, comprising a first node and an adjacent second node, for determining an uplink received power target value of the second node, to be used by a user equipment which is to be served by the second node, the downlink power capacity of the first node exceeds the downlink power capacity of the second node. The method comprises establishing the uplink received power target value of the first node, obtaining the downlink power capacity of the first node, obtaining the downlink power capacity of the second node, calculating the difference in downlink power capacity between the first node and the second node, and determining the uplink received power target value of the second node, based on the calculated difference in downlink power capacity between the nodes and the established uplink received power target value of the first node.

Description

technical field [0001] The present invention relates to methods and devices in wireless networks. In particular, it relates to a mechanism for determining an uplink receive power target value of a second node to be used by a user equipment to be served by the second node. Background technique [0002] In mixed heterogeneous networks with different cell sizes, usually different downlink power levels are used, which present different cell sizes. For example, there may be a 1OdB-2OdB difference between a macro site and a micro site. There are several different nodes that are expected to be deployed with different downlink power levels, such as macro base stations, micro base stations, pico base stations, femto base stations, repeaters and repeaters. [0003] A macro base station may be referred to as a regular base station that uses a dedicated backhaul and is open to public access. Typical transmit power may eg be ~43dBm and antenna gain may be ~12-15dBi. [0004] A pico b...
