Abstract: In a wireless communication network a user device, UE, and a base station, gNB, are provided. The UE monitors one or more paging occasions, POs, for a paging signal directed to the UE by the base station network and receives, ahead of an upcoming PO, a paging early indication, PEI, the PEI indicating whether the UE is to expect a paging signal in the upcoming PO. Paging early indication, PEI, enhancements, for example for improving a power saving behavior of a user device, are described.

Abstract: A radio-frequency integrated circuit includes a first radio-frequency channel and a first phase shifter in the first radio-frequency channel for setting a phase of the first radio-frequency channel based on predetermined phase values of a modulation scheme for signals of the first radio-frequency channel. A second phase shifter is provided in the first radio-frequency channel for fine-tuning the phase of the first radio-frequency channel based on fine-tuning information, the second phase shifter having a plurality of passive phase-shifting elements which are each able to be connected into the first radio-frequency channel or able to be disconnected from the first radio-frequency channel. The second phase shifter is configured to change a phase of the first radio-frequency channel by switching a selection of the plurality of passive phase-shifting elements into the first radio-frequency channel in accordance with the fine-tuning information.

Abstract: An ophthalmoscope simulator for simulation and a method for simulation of the handling of an ophthalmoscope, having a support that can be attached to a head of an observer, at least one first imaging display disposed on said support, wherein the display can be placed in front of an eye of the observer for displaying a virtual reality, an ophthalmoscope dummy that can be supported by one hand of the observer, a position recognition system for determining the spatial position and/or orientation of the support and of the ophthalmoscope dummy and a computer for displaying an image of an environment, a patient head and/or at least a portion of the ophthalmoscope dummy on the display.
