Abstract

A technique for providing task priority related information intended for task scheduling in a system (100) is provided. A method implementation of this technique comprises the steps of obtaining, by a first obtaining unit (110), at least one status relating to the system, obtaining, by a second obtaining unit (120), priority information relating to priorities of a plurality of tasks depending on the obtained status, and providing the obtained information for the task scheduling to a task scheduling unit (130).

Claims

1-12. -12. (canceled)

13. A method for providing task priority related information intended for task scheduling in a system, comprising:

obtaining at least one status relating to the system;

selecting, from a plurality of task priority tables, one task priority table depending on the obtained status, wherein the task priority tables comprise, for each task, a sequential or non-sequential order of priority values;

providing the selected task priority table for task scheduling.

14. The method of claim 13 further comprising obtaining an initial priority value for at least one of the plurality of tasks.

15. The method of claim 13 wherein the obtaining the at least one status comprises:

obtaining information regarding at least two statuses relating to the system; and

determining, based on the information, a condition for selecting the task priority table.

16. The method of claim 13 wherein the system is a Layer 1 processing system.

17. The method of claim 13 wherein a first task relates to a reading of broadcast system information on a first frequency and a second task relates to cell search measurements on one or more second frequencies different from the first frequency.

18. A computer program product stored in a non-transitory computer readable medium for providing task priority related information intended for task scheduling in a system, the computer program product comprising software instructions which, when run on a computing device of the system, causes the computing device to:

obtain at least one status relating to the system;

select, from a plurality of task priority tables, one task priority table depending on the obtained status, wherein the task priority tables comprise, for each task, a sequential or non-sequential order of priority values;

provide the selected task priority table for task scheduling.

19. An electronic device adapted to provide task priority related information intended for task scheduling in the device, the device comprising:

a first obtaining unit configured to obtain at least one status relating to the device;

a second obtaining unit configured to select, from a plurality of task priority tables, one task priority table depending on the obtained status, wherein the task priority tables comprise, for each task, a sequential or non-sequential order of priority values;

wherein the selected task priority table is provided for task scheduling.

20. The electronic device of claim 19 wherein the second obtaining unit is configured to obtain an initial priority value for at least one of the plurality of tasks.

21. The electronic device of claim 19 wherein the second obtaining unit is configured to:

obtain information regarding at least two statuses relating to the device;

determine, from the information, a condition for selecting the task priority table.

22. The electronic device of claim 19 wherein the device is configured to provide Layer 1 processing.

23. The electronic device of claim 19 wherein a first task relates to a reading of broadcast system information on a first frequency and a second task relates to cell search measurements on one or more second frequencies different from the first frequency.
