Abstract: There is provided mechanisms for determining calibration of positions of EEG electrodes on a subject. A method is performed by a controller. The method comprises obtaining a set of signals representative of estimated positions for the EEG electrodes when placed on the subject. Each of the estimated positions represents a position of one of the EEG electrodes relative to the subject. The method comprises comparing the set of signals representative of estimated positions to a set of reference signals representative of reference positions. The set of reference positions represents intended positions for the EEG electrodes when placed on the subject. The method comprises determining the calibration of positions of the EEG electrodes using a difference between a property of the obtained signals and the set of reference signals.

Abstract: Embodiments include methods for scheduling processing resources for physical layer, (PHY) communications in a wireless network. Such methods include estimating processing resources needed, during a subsequent second duration, for PHY communications in one or more cells of the wireless network, based on: a first transmission timing configuration for the one or more cells, current workload of radio units, RUs, serving the one or more cells, and information about user data traffic scheduled for transmission or reception in the one or more cells during a first duration. The first duration can precede the second duration by at least a scheduling delay associated with the processing resources. Such methods include sending, to a resource management function, a request for the estimated processing resources during the second duration. Other embodiments include processing systems, wireless networks, PHY task resource schedulers (TRS), computer-readable media, and computer program products embodying such methods.

Abstract: Example methods and apparatus disclosed herein use the “processing margin” at a radio unit (RU) (24) as a control variable for modifying the allocation of virtualized processing resources used by a digital unit (DU) (16) that supports the RU (24). The DU (16) and RU (24) form a radio processing chain with a functional split, in which the DU (16) performs certain processing operations and provides corresponding processed data to the RU (24), which performs further processing for the generation and transmission of the corresponding radio signals. The “slack” between the end of processing in the RU (24) and the corresponding required transmission time represents the processing margin. The processing-margin feedback loop allows for the virtualization of all or part the DU (16), while avoiding the need for the network operator to implement or pay for over-dimensioning of the DU (16), as would be needed to ensure that a static resource allocation meets worst-case processing needs.

Abstract: Systems and methods of managing computational resources are provided. In one exemplary embodiment, a method by a controller (305, 407, 500, 600, 700, 1101) for managing computational resources may include dynamically distributing (801) computational resource shares among sequential services that are mapped to one or more processors (303, 403). Further, each sequential service corresponds to an execution step of a remote application (307, 409). Also, a service chain (313-315, 413-415) comprises at least one sequential service. The dynamical distribution is based on estimated and predetermined tail latencies and average execution times of each sequential service in the service chain as well as the service chain such that the latencies are met. In addition, the one or more service chains are executed contemporaneously.
