Abstract: Disclosed is a method for detecting an acoustic event of interest in a space. In the method acoustic signal data is obtained from sensors and at least some candidate impulses are determined. The candidate impulses are mapped to a representation on a basis of an origin of the candidate impulse in question and it is determined, from the generated representation, at least one indication quantity representing a likelihood of an acoustic event of interest taking place in the specified positions in space and time. Finally, the at least one indication quantity is compared to a predetermined threshold and an indication is generated if the at least indication quantity meets the predetermined threshold. Also disclosed is a computing unit and a computer program product.

Abstract: The present disclosure relates to a user device, an access node device and a central network controller. The user device comprises a transceiver configured to synchronise with a radio communication network; said transceiver further being configured to broadcast a beacon signal comprising at least one reference signal to one or more access node devices of said radio communication network. The access node device comprises a transceiver configured to receive a broadcast beacon signal from a user device synchronised with said radio communication network; and further a processor configured to derive information from said received broadcast beacon signal and to use said derived information in a network procedure of said radio communication network. Furthermore, the present disclosure also relates to corresponding methods, a computer program, and a computer program product.

Abstract: The present invention relates to a method and equipment for adaptively tracking a mobile terminal with millimeter wave radio link by establishing and/or maintaining a link between an access point or base station and a moving terminal where the method comprises changing the arrangement of the transmission directional beams of an access point or base station and the reception directional beams of a mobile terminal in a channel estimation process responsive to motion characteristics of the access point or base station transmitter or the mobile terminal receiver or both the access point or base station transmitter and the mobile terminal receiver. The invention further relates to a corresponding system and an access point or base station and a movable terminal provided with means for implementing the above method.

Abstract: An apparatus for assigning a plurality of access nodes of a wireless communication network to control areas includes a processing apparatus. The processing apparatus is configured to assign each access node in the plurality of access nodes to a control area of a plurality of control areas and to determine a first control phase. The first control phase is a period of time during which the assignment of access nodes to control areas remains constant. The processing apparatus is configured to, when changing from the first control phase to a following second control phase, reassign at least a subset of access nodes which were assigned during the first control phase to a first control area to a second control area and reassign at least a subset of access nodes which were assigned during the first control phase to a third control area to the first control area.

Abstract: An embodiment of an apparatus for determining clusters of access nodes includes a processing apparatus configured to determine a first cluster based on a first metric, wherein the first cluster comprises one or more access nodes for serving at least a first user node, assign further user nodes to be served by the one or more access nodes of the first cluster based on a spatial separation of the further user nodes and a second metric, and determine at least a further cluster by repeating the determining and assigning steps for further access nodes and user nodes.
