Embodiment Construction

[0029] In the following description, different embodiments of the invention will be described in more detail with reference to the accompanying drawings. For purposes of explanation and not limitation, specific details are set forth, such as specific examples and techniques, in order to provide a thorough understanding.

[0030] Embodiments of the present invention propose a method to identify and group remote radios to form logical cells. The method can be performed in a network node, eg an operation & maintenance (O&M) node, a base station, a radio network controller, a radio equipment controller.

[0031] The overall procedure on how to define a logical cell will be described below.

[0032] image 3 A cell plan with a plurality of cells 32, 34, 36 and 38 is schematically presented. Each cell is formed by individual remote radios. The remote radio equipment for each cell typically includes antenna elements and radio frequency generators.

[0033] According to some embo...

Abstract

It is disclosed a method and a network node (502, 70, 90) for selecting a candidate cell (14, 44, 06) to be combined with a target cell (12, 42, 502) having a radio equipment (76) connected to a radio equipment controller (74). The method comprises identifying (612, 82) at least two candidate cells where a time delay in communication between any two of: said at least two candidate cells and the target cell, is below a pre-determined time threshold, selecting (614, 84) the one (44) having the highest connection activity with the target cell; and combining (616, 86) the selected candidate cell (14, 44) and said target cell (12, 42) into a logical cell. Embodiments of the present invention have the advantage that the logical cells being defined provides have a high overall mobile network connectivity improvement.

Description

technical field [0001] The present disclosure relates to logical cells. More particularly, it relates to a method and network node for defining logical cells. Background technique [0002] Deploying heterogeneous networks, where macro networks are supplemented with small cells, is one way to improve the capacity and coverage of mobile networks. [0003] figure 1 A heterogeneous network is illustrated that includes a macro cell 12 , a small cell 14 , a base station 16 of the macro cell 12 , and a base station 18 of the small cell 14 . Small cells are deployed where the coverage and capacity of the macro network need to be improved. [0004] One way to deploy a heterogeneous network is to use a base station architecture based on remote radios and radio controllers. The remote radio includes radio frequency generating means and antenna elements, while the radio controller typically includes baseband signal processing means. Remote radios and radio controllers are usually i...
