Abstract: Systems and methods are described for positioning a Low Altitude Platform Station (LAPS) based drone cells for supporting communication in a 3GPP network. The methods may include receiving at least one feedback parameter from a UE pertaining to a current network traffic flow and mobility with respect of the UE. The UE is selected for an aerial network through a drone base station (DBS) cell based on service requirement determined from the feedback parameter. Further, a position for at least one DBS-cell is determined with respect to the at least one selected UE based on the at least one parameter to serve the selected UE. An aerial-communication link is established between the selected UE and the DBS cell by deploying one or more LAPS as a drone base station (DBS) in accordance with the determined position of DBS-cell to thereby augment a network connectivity of the selected UE.

Abstract: A method for preventing a task-signal deadlock arising due to contention for a mutex in a real-time operating system (RTOS) includes detecting, by a processing unit, a signal notification sent to a task for execution of a signal handler; identifying, by the processing unit, a mutex to be acquired by the signal handler, when the signal notification is detected; determining whether the identified mutex has been acquired by the task; and utilizing, by the processing unit, an alternative stack for execution of the signal handler, in response to determining that the mutex has been acquired by the task, for preventing a task-signal deadlock during the execution.

Abstract: An apparatus is configured to collect information related to a first activity and analyze the collected information to determine decision data. The information is stored in a first list of the source processing core for scheduling execution of the activity by a destination processing core to avoid cache misses. The source processing core is configured to transmit information related to the decision data using an interrupt, to a second list associated with a scheduler of the destination processing core, if the destination processing core is currently executing a second activity having a lower priority than the first activity.

Abstract: Various example embodiments herein provide a computerized method for scheduling a plurality of tasks for an operating system on a multicore processor. The method includes identifying the plurality of tasks to be executed on the multicore processor and determining a task schedule for scheduling of the plurality of tasks by providing a higher preference to the CPU-bound task than the non CPU-bound task. Further, the method includes scheduling the plurality of tasks on the multicore processor based on the task schedule.
