Abstract
Technologies for scheduling carrier aggregation (CA) for a user equipment (UE) of a cellular network are described. One method of operating a scheduler of a radio access network includes determining a payload size of user data to be exchanged with the UE over a channel. The method further includes analyzing a plurality of parameters associated with a quality-of-service (QOS) requirement of the UE, a quality of the channel, and a plurality of component carriers available at a plurality of bandwidths. The method further includes determining whether and when to activate carrier aggregation (CA) for the UE using at least one additional component carrier of the plurality of component carriers based on the payload size and values of the plurality of parameters.
Claims19
A computing system to facilitate a cellular network, the computing system comprising:
- one or more processing devices;
- and
- memory communicatively coupled with and readable by the one or more processing devices and having stored therein processor-readable instructions which, when executed by the one or more processing devices, cause the one or more processing devices to perform operations comprising:
- determining a payload size of user data to be exchanged with a user equipment (UE) over a channel;
- analyzing a plurality of parameters associated with a quality-of-service (QoS) requirement of the UE, a quality of the channel, and a plurality of component carriers available at a plurality of bandwidths;
- determining whether and when to activate carrier aggregation (CA) for the UE using at least one additional component carrier of the plurality of component carriers based on the payload size and values of the plurality of parameters;
- and
- determining a maximum value of the payload size before activating the CA based on a physical resource block (PRB) utilization level, a maximum number of UEs supportable by a connected cell, data volume, and data throughput of a plurality of channels of the connected cell.
