[0006] However, all CoMP schemes described above require the UE to perform measurements in order to select the best beam / cell / transport format (user bit rate), and this leads to increased processing needs in the UE and the network and high signaling on the radio interface load

Embodiment Construction
[0033] Throughout the figures, the same reference signs are used for similar or corresponding elements.
[0034] To gain a better understanding of the proposed technology, it may be beneficial to start with a brief system overview and / or technical problem analysis.
[0035] As mentioned above, a coordination feature commonly referred to as downlink CoMP can be utilized in order to counteract severe interference scenarios. However, all CoMP schemes described above require the UE to perform measurements in order to select the best beam / cell / transmission format (user bit rate). Standard 3GPP Release 11 introduces TM10 (CSI-RS / IM) enabling tools for fast coordination, but coordination can also be based on 3GPP Release 8 RSRP measurements.
[0036] However, it is not feasible to measure the relationship between the received power of the serving cell and the power of the interfering cell (often referred to as downlink "geometry") by means of Release 8 RSRP / RSRQ measurements for all...

A method for selecting a wireless communication device for measurement configuration in a wireless communication network (1) comprising obtaining (S10) information about signal strength and / or signal quality from a wireless communication device (20) in the wireless communication network (1). at least one of the reported steps. The method also includes the step of determining (S20) whether the wireless communication device (20) is selected for measurement configuration, wherein the measurement configuration includes configuring the wireless communication device (20) to provide information about a serving cell and Measurement reports of received power of neighboring cells, and wherein the step of determining (S20) is based on said at least one obtained report on signal strength and / or signal quality.
Description
technical field [0001] In general, the proposed techniques relate to coordination in heterogeneous wireless communication networks, and more specifically, to measurement configuration of wireless communication devices in such networks. Background technique [0002] Heterogeneous Network (HeNet) deployments are an important part of future radio networks to serve increased capacity and quality requirements. HeNet deployments consist of small cells laid out in an existing macro network. [0003] Small cells generally have lower output power than macro cells and for this reason the coverage of these cells is also smaller than macro cells. A typical deployment of small cells is therefore a localized hotspot such as a train station, where although the traffic load in the small cell is high, the area is usually also covered by surrounding macro cells. [0004] Overlapping coverage also means that macro cells will cause interference to small cells if operating on the same carrier ...
