Problems solved by technology

[0010] While dynamic elevation beamforming is a powerful tool for directing transmitted energy towards UEs of interest, and may potentially increase the signal-to-noise ratio for one or more UEs in a cell, due to the interference caused by the beams, The cost of doing this may be to reduce the signal-to-noise ratio in other UEs in neighboring cells

Embodiment Construction

[0035] On reading the following description, it should be kept in mind that the embodiments listed and illustrated below are by way of example only, and should not be considered as limiting the technology to these embodiments. Indeed, wireless systems including LTE, WCDMA, WiMax, UMB and GSM could also benefit from exploiting the ideas covered within this technique.

[0036] Note also that terms such as network node and user equipment (UE) should not be taken as implying some hierarchical relationship between the two devices. In general, a network node can be considered device 1 and a "UE" can be considered device 2, whereby the two devices communicate with each other over a certain radio channel.

[0037] As mentioned earlier, while it may be beneficial in increasing data throughput in a cell, beamforming may have a negative impact on data throughput in neighboring cells due to interference. Therefore, to maximize system performance (not just that of a cell), the impact of i...

Abstract

A method in a network node (800) for selecting a beam candidate (A, B, C) in a wireless communication network, comprising: obtaining (900) information including information indicating signal quality for a plurality of beam candidates information; assigning (910) a factor to each of the plurality of beam candidates, the factor indicating signal interference generated by the corresponding beam candidate; and taking into account at least the associated signal quality and the factor assigned to the selected beam candidate A beam candidate is internally selected (920). The technology also relates to a method in a UE (700), a network node (800) and a UE (700).

Description

technical field [0001] The present technique generally relates to interference mitigation, and in particular it relates to methods and apparatus for selecting beam candidates in a wireless communication network, on the part of network nodes and user equipment. Background technique [0002] Radio propagation is the behavior of radio waves as they travel, or travel, from one point to another. Depending on the environment between two points, a radio wave will be affected by several factors during its propagation, such as reflection, diffraction, absorption and scattering. Furthermore, when transmitted from the network node 110 to the UE 130, the propagation may be along the Figure 1a The straight line-of-sight path shown, where beam 120 is at an elevation angle transmitted from the network node 110 to the UE 130 . Propagation may also follow non-line-of-sight paths, eg, formed by reflections from different scatterers. Non-line-of-sight is critical in any communication syst...
