Abstract
A method for performing a scheduling algorithm with minimum resource scheduling in a mobile communication system, comprising the steps of scheduling (10) allocation units for a user or service in a scheduling frame, checking whether (20) the allocation units scheduled for a user or service in a particular scheduling frame meet a resource constraint, and releasing the allocation units (40) scheduled for a user or service for that particular scheduling frame for based on the result of the checking step for resource constraint. The invention also concerns a scheduler in a mobile communication system, a base station and mobile terminal comprising such a scheduler and a mobile communication system.
Claims19
A method for performing a scheduling algorithm with minimum resource scheduling in a mobile communication system, comprising:
- scheduling allocation units for a user or service on a per-scheduling frame basis, wherein each scheduling frame comprises a plurality of allocation units,
- checking whether the allocation units that are scheduled for the user or service in a current scheduling frame meet at least one resource constraint,
- releasing the allocation units that are scheduled for the user or service for said current scheduling frame in response to a result of checking whether the allocation units that are scheduled for the user or service in said current scheduling frame meet the at least one resource constraint, and
- re-scheduling the released allocation units in the current scheduling frame to at least one other user or service,
- wherein the method further comprises:
- checking whether at least one other resource constraint is not violated by the releasing of the allocation units, and
- performing the releasing of the allocation units that are scheduled for the user or service only if the at least one other resource constraint is not violated by the releasing of the allocation units.
A scheduling apparatus for use in a mobile communication system and for performing a scheduling algorithm with minimum resource scheduling, comprising:
- a scheduling unit comprising a processor for scheduling allocation units for a user or service on a per-scheduling frame basis, wherein each scheduling frame comprises a plurality of allocation units,
- a checking unit for checking whether the allocation units that are scheduled for the user or service in a current scheduling frame meet at least one resource constraint and for providing a result of the checking, and
- a releasing unit for releasing the allocation units that are scheduled for the user or service for the current scheduling frame in response to the result provided by the checking unit,
- wherein the scheduling unit is configured to re-schedule the released allocation units in the current scheduling frame to at least one other user or service, and
- wherein the scheduling apparatus further comprises a determining unit for determining whether at least one other resource constraint is not violated by the releasing of the allocation units and for allowing the releasing of the allocation units that are scheduled for the user or service only if the at least one other resource constraint is not violated by the releasing of the allocation units.
