Embodiment Construction

[0047] As mentioned above, it should be emphasized that when the term "comprises / comprises" is used in this specification, it is used to specify the presence of stated features, integers, steps or components, but does not exclude the presence or addition of one or more other A feature, integer, step, component, or grouping thereof. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise.

[0048] Embodiments of the present disclosure will be more fully described and exemplified below with reference to the accompanying drawings. However, the solutions disclosed herein may be implemented in many different forms and should not be construed as being limited to only the embodiments set forth herein below.

[0049] As mentioned above, the entire antenna array is usually phase steered so that it has maximum antenna gain in one particular direction in analog beamforming. A more flexible so...

Abstract

A method is disclosed for controlling operations of an antenna array comprising two or more controllable sections and antenna ports connected to transceiver circuitry. The method comprises determininga scenario of transmission or reception by the antenna array, and configuring the transceiver circuitry responsive to the determined scenario. The scenario is defined in terms of a requirement for anumber of users intended as receivers or transmitters, respectively, of the transmission or reception and in terms of one or more of: a path loss requirement, a peak rate requirement, and a traffic capacity requirement. The configuration comprises, for the transmission or reception, one or more of: allocating a number of sections of the two or more sections of the antenna array and determining a subdivision of the allocated sections, determining a number of information data layers for multiple-input multiple-output (MIMO) application, and allocating a bandwidth. Corresponding arrangement, network node, wireless communication device and computer program product are also disclosed.

Description

technical field [0001] The present disclosure relates generally to the field of wireless communications. More specifically, it relates to operational control of active antenna arrays (Advanced Antenna Systems, AAS) for wireless communications. Background technique [0002] One technique for improving the performance of wireless communication systems is the use of Advanced Antenna Systems (AAS). For example, this technology is considered with regard to the standardization and implementation of the fifth generation cellular communication system (5G). Properly steered advanced antenna arrays can allow beamforming for transmission and / or reception, which can be used to increase the capacity and / or coverage of a cellular communication system. [0003] An antenna array or array antenna can be controlled by controlling the phase of the signals at the different antenna elements of the antenna array. Alternatively, the antenna array can be controlled by controlling the time delays...
