Abstract: A method for managing operational temperature conditions of one or more base stations being executed at a central computing device in a communication system is provided. The method includes acquiring initial operational parameters for each local computing device of a first group of local computing devices associated with the one or more base stations. The method further includes determining one or more clusters by grouping each local computing device of the first group of local computing devices under one of the determined clusters based on the acquired operational parameters. The method further includes training, a central machine learning (ML) model for each determined cluster. The method further includes acquiring, for each local computing device of a second group of local computing devices associated with the one or more base stations, updated operational parameters. The method further includes computing an operational difference measure of the second group of local computing devices using the acquired updated operational parameters. The method further includes determining optimized operational temperature conditions to be transmitted to the second group of local computing devices by using distributed ML, in response to determining that the computed operational difference measure is less than a threshold value.

Abstract: Embodiments herein disclose, e.g., a method performed by a network node (12), in a wireless communications network (1), for charging a rechargeable power source in the network node (12). The network node (12) obtains an operational parameter to an operation of the network node (12), wherein the operational parameter is based on an output of a computational model. The computational model is based on a state of charge of the rechargeable power source, a parameter related to outage of a power grid, and a QoS parameter relating to radio communication in the wireless communications network. The network node (12) further applies, during a charging of the rechargeable power source, the operational parameter to the operation of the network node (12).

Abstract: A method is provided for determining bias of machine learning models. The method comprises: forming a training dataset comprising input data samples provided to a remote machine learning model developed using a machine learning process, and corresponding output data samples obtained from the remote machine learning model; training a local machine learning model which approximates the remote machine learning model using a machine learning process and the training dataset; and interrogating the trained local machine learning model to determine whether the remote machine learning model is biased with respect to one or more biasing data parameters.

Abstract: A method performed by a first network node (111). The method is for handling charging of a wireless device (130). The first network node (111) and the wireless device (130) operate in a wireless communications network (100). The first network node (111) modulates (307) one or more beam forming beams (121) in an antenna array (124) controlled by the first network node (111) with a pulse width modulation. The first network node (111) then charges(308), wirelessly, the wireless device (130), with the modulated one or more beam forming beams (121).

Abstract: Decision-making equipment (22) is configured for link change decision-making using reinforcement learning. The decision-making equipment (22) is configured to track rewards (30-1,…30-M) earned for, and outcomes (28-1,…28- M) of, respective link change decisions (26-1,…26-M). In some embodiments, possible outcomes of a link change decision to change a serving link of a wireless device to a target link include at least: a change of the serving link of the wireless device from the target link to another link; and a network-initiated disconnect of the wireless device from the target link. Regardless, the decision- making equipment (22) is also configured to make a link change decision (28- (M+1)) based on the tracked rewards (30-1,…30-M) and outcomes (28-1,…28-M).

Abstract: A regulator system (24) of a regulator regulates administration of subscription identifiers. The regulator system (24) is configured to receive, from either an operator system (10) of a wireless communication network operator or an enterprise system of an enterprise, a record that includes information about administration of a subscription identifier associated with the wireless communication network operator. The regulator system (24) is also configured to verify whether administration of the subscription identifier as indicated by the record conforms to one or more rules (34) governing administration of subscription identifiers. The regulator system (24) is further configured to, depending on the verification, approve or reject the record for addition to a permissioned distributed database (26) (e.g., a permissioned blockchain) that is distributed at least in part between the regulator system (24) and either the operator system (10) or the enterprise system.

Abstract: The present disclosure relates to reactive power control in a power system (28). Based on information from a controller (25, 70) scheduling data traffic in a processing arrangement (26), a super capacitor unit (29) is activated, whereby reactive power is fed to a system bus of said power system (28). The controller (25) is configured to have information at time t(n) about the data traffic workload of the processing arrangement at time t(n+1). By triggering discharge of the super capacitor unit based on super capacitor data at time t(n+1), transients on a system bus voltage are, at least in part, smoothed out at time t(n+1), which reduces the need for reactive power of the power system, where said transients are related to the data traffic workload of the processing arrangement. The power efficiency of the power system (28, 38, 48) can be improved by 3 - 4 % by the reduction of the need for reactive power from a power grid (21, 31, 41), for which reason the electrical bill of an operator is reduced.

Abstract: A first audio signal is received from a primary audio signal input. The first audio signal that is associated with a first importance designation indicator (IDI) that indicates an importance of the first audio signal with respect to one or more other audio signals in the indoor environment, wherein the first audio signal includes a primary audio signal that is to be enhanced. A second input indicative of a second audio signal is received from a secondary audio signal source. The second audio signal is associated with a second IDI indicating the importance of the second audio signal. A determination that the first audio signal includes the second audio signal is performed. A modification, based on the first IDI and the second IDI, of the first audio signal is performed to obtain a modified version of the first audio signal that enhances the primary audio signal.
