Abstract: To configure a set of user devices, which comprises one or more user devices, to monitor a subset of beams, at least one past beam sequence indicating one or more beams, which served the set is determined, and inputted to a trained model which outputs a probability distribution. Then as many beams as is a number of beams determined for the set to monitor is selected from the probability distribution according to a first criteria, and the set of user devices is configured to monitor and report beams in the beam group. Past beam sequences are also used in training. From the past sequences, set-specifically, past beams that served a set within a first time interval are determined to be used as training data, and future beams that served the set within a second time interval following the first time interval are determined to be used as validation data.

Abstract: There is provided a method, computer program and apparatus for causing an apparatus to perform: determining that a first non-terrestrial apparatus coverage area provided by a non-terrestrial apparatus will at least partially overlap with a first access coverage area provided by a terrestrial access network node at and/or during a first time; determining a first Doppler shift correction value, the first Doppler shift correction value corresponding to a frequency shift resulting from a relative velocity difference between the non-terrestrial apparatus and the terrestrial access network node at and/or during the first time; determining at least one first shifted non-terrestrial apparatus frequency by correcting at least one transmission and/or reception frequency of the non-terrestrial apparatus using the first Doppler shift correction value; and causing the terrestrial access network node to abstain from transmitting and/or receiving signalling on resources corresponding to the at least one first shifted non-terrestrial apparatus frequency.

Abstract: According to an aspect, there is provided an apparatus for the performing the following. The apparatus implements, separately for at least one downlink beam, a reinforcement learning model, where a state defines which of the plurality of uplink beams belong to a priority beam set for uplink reception corresponding to a downlink beam, an action is defined as an addition of a new uplink beam to the priority beam set, a removal of an uplink beam from the priority beam set or doing nothing and a reward is calculated based on a change in uplink signal-to-noise ratio due to an action adjusted with a cost for taking the action. The apparatus calculates iteratively at least one optimal state using at least one reinforcement learning model based on uplink signal-to-noise ratio statistics and on the plurality of optimal downlink beams for transmission to said plurality of terminal devices.
