Abstract
A scheduling method in a wireless communication system using a dual cell. The method includes determining a scheduling metric value of a user equipment (UE) with respect to each of at least two carriers. The method also includes determining a priority of the UE based on the scheduling metric value, per carrier. The method further includes selecting a UE according to the priority of the UE per carrier. The method also includes determining whether the selected UE has the same priority per carrier, and when the selected UE has the same priority, randomly selecting at least one carrier and allocating a resource to the UE based on the selected carrier.
Claims20
A scheduling method in a wireless communication system using a dual cell, the method comprising:
- determining a scheduling metric value of a user equipment (UE) with respect to each of at least two carriers;
- determining a priority of the UE based on the scheduling metric value, per carrier;
- selecting a UE according to the priority of the UE per carrier;
- and
- determining whether the selected UE has the same priority per carrier, and when the selected UE has the same priority, randomly selecting at least one carrier and allocating a resource to the UE based on the selected carrier.
A scheduling method in a wireless communication system using a dual cell, the method comprising:
- determining a scheduling metric value of a user equipment (UE) with respect to each of at least two carriers;
- selecting a carrier corresponding to the greatest scheduling metric value of the UE by comparing the scheduling metric per carrier of the UE;
- sorting UEs using the selected carriers based on a priority;
- and
- allocating a resource to the UE using the selected carrier according to the priority of the UE.
A scheduling method in a wireless communication system using a dual cell, the method comprising:
- determining a scheduling metric value of a user equipment (UE) with respect to each of at least two carriers;
- sorting a scheduling metric value of the UE regardless of the carriers;
- and
- allocating a resource to a corresponding UE based on a sort order according to the scheduling metric value of the UE,
- wherein the allocating of the resource to the corresponding UE based on the sort order according to the scheduling metric value of the UE comprises:
- determining whether there is an available resource in a current order based on a corresponding carrier, and allocating the resource when there is the available resource;
- and
- when there is no available resource, determining whether there is an available resource in a next order based on the corresponding carrier.
An apparatus of a base station in a wireless communication system using a dual cell, the apparatus comprising:
- a scheduler configured to determine a scheduling metric value of a user equipment (UE) with respect to each of at least two carriers, determine a priority of the UE based on the scheduling metric value per carrier, select a UE according to the priority of the UE per carrier, determine whether the selected UE has the same priority per carrier, and when the selected UE has the same priority, randomly select at least one carrier and allocate a resource to the UE based on the selected carrier.
An apparatus of a base station in a wireless communication system using a dual cell, the apparatus comprising:
- a scheduler configured to determine a scheduling metric value of a user equipment (UE) with respect to each of at least two carriers, select a carrier corresponding to the greatest scheduling metric value of the UE by comparing the scheduling metric per carrier of the UE, sort UEs using the selected carriers based on a priority, and allocate a resource to the UE using the selected carrier according to the priority of the UE.
An apparatus of a base station in a wireless communication system using a dual cell, the apparatus comprising:
- a scheduler configured to determine a scheduling metric value of a User Equipment (UE) with respect to each of at least two carriers, sort a scheduling metric value of the UE regardless of the carriers, and allocate a resource to a corresponding UE based on a sort order according to the scheduling metric value of the UE,
- wherein, to allocate the resource to the corresponding UE based on the sort order according to the scheduling metric value of the UE, the scheduler determines whether there is an available resource in a current order based on a corresponding carrier, allocates the resource when there is the available resource, and determines whether there is an available resource in a next order based on the corresponding carrier when there is no available resource.
