Abstract: A RL agent performs a RL process to configure at least one Discontinuous Reception, DRX, cycle for a User Equipment, UE. An action is selected by the RL agent in an action space. Each action in the action space corresponds to a DRX cycle configuration. The RL agent sends to the UE indication to use the DRX cycle configuration corresponding to the selected action. The RL agent receives state information computed over at least one DRX cycle configured based on a DRX cycle configuration indicated by the RL agent. The RL agent computes a reward on the basis of the state information.

Abstract: A method comprises receiving from a user equipment supporting Carrier Aggregation, CA, Channel State Information, CSI, reports for a Primary Component Carrier, PCC, for one or more previous time slots and for a current time slot. CSI reports for a Secondary Component Carrier, SCC are received from the user equipment. The CSI reports include a CSI report for a previous time slot. Each CSI report includes a value of a channel state indicator. The method further comprises predicting a value of the channel state indicator for the SCC for the current time slot; the value is predicted based upon one or more values of the channel state indicator reported for the PCC for the one or more previous time slots and for the current time slot, and at least one value of the channel state indicator reported for the SCC for the previous time slot.

Abstract: In some embodiments, a computing system maintains, in a memory, information on one or more terminal devices, a dictionary of beams and information on a spatial grid. The computing system maps each terminal device to the spatial grid based on up-to-date results of radio measurements and calculates, for each spatial element, a load caused by the one or more terminal devices based on the mapping. The computing system evaluates, for each combination of a beam and a terminal device, a reference signal received power, RSRP, based on results of the radio measurements. The computing system calculates a first map of expected spatial distribution of traffic based on the calculated loads and beam-specific second maps of expected RSRP based on the values of the RSRP. Finally, the computing system causes performing beamforming optimization based on the first map and second maps.
