Abstract: In some examples, a node for a telecommunication network includes a neural-network-based receiver for uplink communications. The node is configured to modify the neural-network-based receiver to generate a set of modified receiver frameworks defining respective different versions for the receiver, using each of the modified receiver frameworks, generate respective measures representing bits encoded by a signal received at the node, calculate a value representing a variance of the measures, and on the basis of the value, determine whether to select the signal received at the node for use as part of a training set of data for the neural-network-based receiver.

Abstract: According to an aspect, a method in the radio head comprises receiving a reference signal from a terminal device, and computing a channel estimate on the basis of the reference signal and transferring the channel estimate with a first precision level to the network node over a link between the radio head and the network node. The first precision level defines a first number of bits carrying the channel estimate, then the method determines to change the precision level and, in response to the determining, transfers the channel estimate or a further channel estimate with a second precision level to the network node. The second precision level defines a second number of bits carrying the channel estimate or the further channel estimate, the second number being different from the first number.

Abstract: 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.

An energy management module determines one or more power flows transmitted over at least one electrical power grid.

The one or more identification signals distinguish the one or more power flows from one or more other power flows transmitted over the at least one electrical power grid.
