Abstract
Methods are provided for determining that a traffic condition at a Primary Cell (PCell) used in New Radio Carrier Aggregation (NR CA) exceeds a congestion threshold. The method further includes determining that a user equipment (UE) attached to the PCell is disposed in a downlink coverage area of at least one Secondary Cell (SCell) used in the NR CA and based on the traffic condition at the PCell exceeding the congestion threshold and the UE being disposed in the downlink coverage area of the at least one SCell, reassigning at least a portion of downlink traffic between the PCell and the UE to a first SCell of the at least one SCell.
Claims18
A computer-implemented method for offloading one or more user equipment (UE) in a carrier aggregation communications system, the method comprising:
- determining that a traffic condition at a Primary Cell (PCell) used in New Radio Carrier Aggregation (NR CA) exceeds a congestion threshold;
- identifying the one or more UE that are attached to the PCell and disposed in a downlink coverage area of at least one Secondary Cell (SCell) used in the NR CA;
- and
- based on the traffic condition at the PCell exceeding the congestion threshold and the one or more UE being disposed in the downlink coverage area of the at least one SCell, reassigning at least a portion of the one or more UE to a first SCell of the at least one SCell.
One or more non-transitory computer-readable media having a plurality of executable instructions embodied thereon, which, when executed by one or more processors, cause the one or more processors to perform a method for transmitting additional data through a communication stream, the method comprising:
- determining that a traffic condition at a Primary Cell (PCell) used in New Radio Carrier Aggregation (NR CA) exceeds a congestion threshold;
- determining that one or more user equipment (UE) attached to the PCell is disposed in a downlink coverage area of at least one Secondary Cell (SCell) used in the NR CA;
- and
- based on the traffic condition at the PCell exceeding the congestion threshold and the UE being disposed in the downlink coverage area of the at least one SCell, reassigning at least a portion of the one or more UE to a first SCell of the at least one SCell.
A computer system comprising:
- one or more processors;
- and
- one or more non-transitory computer-readable storage media, coupled with the one or more processors, having instructions stored thereon, which, when executed by the one or more processors, cause the computing system to provide:
- means for determining that a traffic condition at a Primary Cell (PCell) used in New Radio Carrier Aggregation (NR CA) exceeds a congestion threshold;
- means for determining that one or more a user equipment (UE) attached to the PCell is disposed in a downlink coverage area of at least one Secondary Cell (SCell) used in the NR CA;
- and
- means for reassigning at least a portion of the one or more UE to a first SCell of the at least one SCell based on the traffic condition at the PCell exceeding the congestion threshold and the at least the portion of the one or more UE being disposed in the downlink coverage area of the at least one SCell.
