This document discloses a solution for detecting interference in a radio access network. According to an aspect, a method includes as performed by a network node of the radio access network: acquiring a first equalized signal representing a signal received by a first radio head serving a terminal device, the first equalized signal including a signal received by the first radio head from the terminal device; acquiring a second equalized signal representing a signal received by a second radio head not serving the terminal device, wherein the second radio head is spatially distant from the first radio head; cross-correlating the first equalized signal with the second equalized signal and determining, on the basis of said cross-correlating, whether or not the second equalized signal also includes a signal received from the terminal device; and as a result of the second equalized signal being determined to include the signal received from the terminal device, causing execution of an interference management action.

Co-occurrence data representing e.g. preferences and facts observed in a plurality of situations may be stored in a matrix as combinations of high-dimensional sparse vectors. The matrix may be called e.g. as an experience matrix. The data stored in the experience matrix may be subsequently utilized e.g. for predicting a preference of a user in a new situation. Co-occurrence data may be stored in the experience matrix may be updated by a method comprising determining a first word based on a state of a system and/or based on a physical quantity detected by a sensor, forming a first word group comprising the first word and a second word, associating the first word and the second word with a common sparse vector, associating the first word words with a first vector of a matrix, associating the second word with a second vector of the matrix, modifying the first vector of the matrix by adding contribution of the common sparse vector to the first vector of the matrix, and modifying the second vector of the matrix by adding contribution of the common sparse vector to the second vector of the matrix.

According to an aspect, there is provided a network node comprising means for performing the following. Initially, a trained machine learning algorithm for predicting a probability of failed delivery of data packets based on measurements is maintained in a database. The network node performs, for each of its wireless communication links, the following. The network node causes performing measurements relating to a first wireless communication link to form a measurement data set and predicts, using the trained machine learning algorithm and the measurement data set, a probability of failed delivery of a data packet over the first wireless communication link. The network node determines whether the probability of failed delivery of the data packet exceeds a threshold. If it does, the network node transmits to a first receiver the data packet over the first wireless communication link and one of a copy of the data packet and redundancy data.

The invention relates to determining a context of a system so that the system can be controlled or the context information be used in the system. The context of a system is described with tags or words that characterize e.g. the state of the system, the surroundings of the system and the state of the user. These tags are determined at multiple time instances. The tags are collected over a first time span and a second time span, and the two (or more) sets of tags are used to determine the context of the system. If the determination using the two sets gives a different result, that is, there is a large distance between the two derived contexts, it is determined that a change in context has occurred. Detecting the change in context can be used to control the system, e.g. by changing the applications presented to the user on the user interface, or by changing the state and/or priority of applications.

A method, apparatus and computer program product are provided to permit audio signals to provide additional information to a user regarding the distance to the source of the audio signals, thereby increasing a user's situational awareness. In the context of a method, a distance and a direction from a user to an object are determined. The method also scales the distance to the object to create a modified distance within a predefined sound field region about the user. The method also causes an audio cue relating to the object to be audibly provided to the user. The audio cue is such that the object appears to be located within the predefined sound field region in the direction and at the modified distance from the user from the user.

Systems and techniques for providing data to a user in the form of perceived light signals caused by transcutaneous stimulation of the user's optic nerve. User output data, suitably representing data collected, generated, or processed by a data processing device, is used to generate user output data. The user output data is converted to representations corresponding to light signals, and control functions are performed to cause generation of electrical impulses which, when applied to the skin of a user, stimulate the optic nerve of the user so as to cause the user to perceive the light signals.

In an embodiment an apparatus includes a graphical display panel and a loudspeaker. The panel has a display layer for displaying images and defines a plurality of apertures penetrating through at least the display layer. The loudspeaker includes a diaphragm arranged substantially parallel to the display layer. Sound from the loudspeaker diaphragm is directed outside a host device through the apertures. The speaker may be an electret or a piezo-electric speaker for thinness. There may be apertures on an opposed side of the host device housing to achieve a dipole pattern which is directed and gives acoustic privacy to the user, or a rear acoustic cavity for a monopole pattern which more broadly disperses the sound. One illustrated embodiment is selectable between monopole and dipole. Size and total area of the holes determines acoustic resistance and so a method is described to determine those from physical parameters of the display panel.
