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: 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: A modulation and coding scheme for a transmission to an apparatus may be selected by at least sampling a posteriori probability distribution that has been calculated using a first probability distribution and a second probability distribution. The first probability distribution is calculated using at least a newest first feedback and a plurality of older first feedbacks, a first feedback indicating channel quality. The second probability distribution is calculated using at least a newest second feedback and a plurality of older second feedbacks, a second feedback indicating a success or failure of an earlier transmission transmitted from the apparatus.

Abstract: There is provided a method for a first network element of a wireless communication network, the method comprising: obtaining blanked subcarrier index data indicating one or more blanked subcarriers in a time-frequency resource grid; initiating reception of a transmission from a second network element of the wireless communication network on said time-frequency resource grid; causing performing an interference measurement on said one or more blanked subcarriers to obtain interference measurement data on said one or more blanked subcarriers; and outputting the interference measurement data for detecting a presence of radio jamming.
