Abstract: According to an aspect, there is provided an apparatus for performing the following. The apparatus obtains predicted Doppler spectrum information for a propagation channel between a first terminal device and one of an access node or a second terminal device calculated using a radio-aware digital twin. The predicted Doppler spectrum information includes information on one or more Doppler frequencies of a predicted Doppler spectrum resulting from reflections from one or more terminal devices capable of movement under control of the digital twin. The apparatus causes performing of measurements of one or more reference signals by a device associated with the propagation channel to a form a channel estimate. The apparatus calculates a measured Doppler spectrum based on the channel estimate and filters out the one or more Doppler frequencies from it. The apparatus adjusts a beam refinement interval of the device based on the filtered measured Doppler spectrum.

Abstract: As solution for selection of power control parameters is presented. The solution comprises determining, from a given set of radio access network parameters, a selection of radio access network parameters which have an effect on uplink power control, and training a neural network to determine uplink power control parameters, utilising as an input the selection of radio access network parameter, and utilising the trained neural network, with as an input the selection of radio access network parameters, obtain as an output a set of initial uplink power control parameters.

Abstract: There are provided measures for data collection optimization. Such measures exemplarily comprise selecting, out of a plurality of radio equipment entities, a set of radio equipment entities, based on correlation information reflecting at least temporal and/or spatial correlation among data from said plurality of radio equipment entities, and determining a movement trajectory for a movable data collection entity configured for reading-out data from said plurality of radio equipment entities, said movement trajectory being a path with a minimum length among paths connecting all data read-out zones corresponding to all radio equipment entities of said set of radio equipment entities.

Abstract: A solution for radio jamming detection is disclosed. The solution comprises determining M subcarriers in a time-frequency resource grid to be blanked and outputting the M subcarriers in the time-frequency resource grid to be blanked by performing at least one of the following operations: first determination of a number M of subcarriers in a time-frequency resource grid to be blanked based on probability of detecting a jammer attack or on channel quality of subcarriers in the time-frequency resource grid, second determination of which M subcarriers in the time-frequency resource grid are blanked taking into account the channel quality of subcarriers in the time-frequency resource grid.

Abstract: An apparatus is provided that includes circuitry for decomposing an input signal to multiple substantially constant-envelope components and an outphasing path for each substantially constant-envelope component. The apparatus also includes a modulator for discrete phase control in each outphasing path, an amplifier in each outphasing path and a combiner for combining output signals from the outphasing paths. A system and method are also provided.
