Embodiments herein disclose, e.g., an arrangement for handling radio signals, wherein the arrangement has an elongated housing. The elongated housing has at least one antenna processing unit (APU) and at least two groups of antenna elements, wherein each group of antenna elements includes antenna elements and a beamforming unit that generates one or more beams. The at least one APU is connected to both the groups of antenna elements.

Arrangement and method performed therein for handling communication

An antenna arrangement comprises a body which in turn comprises a plurality of antenna devices, the antenna arrangement being characterized in that the body has a flexible structure and an elongated shape.

Antenna arrangement for distributed massive MIMO

An antenna arrangement comprising a body comprising a plurality of antenna devices, the antenna arrangement being characterized in that the body having a flexible structure and an elongated shape and wherein the antennas are arranged in a non-orthogonal co-polarized manner.

An antenna system () comprises a Centralized Processing Unit (); at least two antenna units () connected to the CPU () by cables. Each antenna unit () comprises at least one connector; one or more antenna elements () and one or more 5 Antenna Processing Units () connected to the one or more antenna elements (). The one or more antenna processing units () are connected to a data bus connected to the at least one connector.

Antenna system for use in distributed massive MIMO networks

An antenna system () with distributed power supply is disclosed. The antenna system () comprises a CPU () comprising a central power supply (), multiple antenna units (. . . ) connected to the CPU by cables and at least one distributed power supply unit () located at someplace along a chain of antenna units. At least one antenna unit () receives power from the central power supply (). In the antenna system (), at least one antenna unit () receives power from another antenna unit (), at least one antenna unit () receives power from the at least one distributed power supply unit () such that at least two power supply domains () are set up. In each power supply domain, a number of antenna units are connected to the same power supply.

Multiple-input multiple-output communication system with scalable power supply

An antenna arrangement () comprising a body () comprising a plurality of antenna devices (), the antenna arrangement being characterized in that the body () having a flexible structure and an elongated shape and wherein the antennas are arranged in a non-orthogonal co-polarized manner.

A method for a primary user device of a spectrum license used for allowing radio communication in a wireless communication network covering a local area to which the spectrum license is limited, wherein the method comprises: providing at least one spectrum compliance probe within the local area; detecting, using the at least one spectrum compliance probe, within the local area one or both of (i) a first interference caused by a first signal originating from within the local area, wherein the first interference is not allowed by the spectrum license, and (ii) a second interference caused by a second signal originating from outside the local area, wherein the second interference is not allowed by the spectrum license; and controlling the radio communication in response to said detection.
