Abstract: A method for managing allocation of radio resources to users in a cell of a communication network during an allocation episode is disclosed. The method comprises generating a representation of a scheduling state of the cell for the allocation episode and generating a radio resource allocation decision for the allocation episode by performing a series of steps sequentially for each radio resource or for each user in the representation. The steps comprise selecting a radio resource or a user and using a trained neural network to update a partial radio resource allocation decision for the allocation episode on the basis of a current version of the scheduling state representation and updating the scheduling state representation to include the updated partial radio resource allocation decision. The method further comprises initiating allocation of cell radio resources to users during the allocation episode in accordance with the generated radio resource allocation decision.

Abstract: Methods and apparatuses for realizing and enabling a requested computational main task by operation of a task manager and a service node. The task manager defines a set of sub-tasks that accomplish the main task, and sends a source code to the service node including a device instruction for a device connected to the service node, to fetch and execute a sub-task from the task manager. The service node then sends the source code to the device which accordingly fetches and executes the sub-task according to the instruction. When the task manager has received enough sub-task results such that the main task has been completed, it returns an aggregated total result of the main task in response to the main task request.
