Abstract
Performing inter-band carrier aggregation based on device capability includes monitoring a dominant type of wireless devices in a wireless sector based on whether or not they are capable of inter-band carrier aggregation, and enabling or disabling inter-band carrier aggregation in the sector based on the dominant type. Enabling/disabling inter-band carrier aggregation can include allowing or preventing usage of usage of a low-frequency carrier as a primary component carrier aggregated with a high-frequency carrier as a secondary component carrier. Carriers using FDD and TDD duplexing modes are included.
Claims20
A method for performing inter-band carrier aggregation based on device capability, the method comprising:
- determining a number of wireless devices capable of inter-band carrier aggregation in a wireless sector is greater than a number of wireless devices incapable of inter-band carrier aggregation in the wireless sector;
- and
- when the number of wireless devices capable of inter-band carrier aggregation is greater than the number of wireless devices incapable of inter-band carrier aggregation, enabling usage of a low-frequency carrier as a primary component carrier for a carrier aggregation mode of operation.
A system for performing inter-band carrier aggregation based on device capability, the system comprising
- an access node configured to deploy at least a first carrier utilizing a first frequency band and a second carrier utilizing a second frequency band, the second frequency band comprising higher frequencies than the first frequency band;
- and
- a processing node communicably coupled to the access node, the processing node being configured to perform operations comprising:
- determining that a majority of throughput usage in a wireless sector is associated with devices capable of performing inter-band carrier aggregation;
- and
- when the majority of throughput usage in the wireless sector is associated with devices capable of performing inter-band-carrier aggregation, enabling the first carrier as a primary component carrier for a carrier aggregation mode of operation.
A processing node for performing inter-band carrier aggregation based on device capability, the processing node being configured to perform operations comprising:
- determining a number of wireless devices capable of inter-band carrier aggregation in a wireless sector is greater than a number of wireless devices incapable of inter-band carrier aggregation in the wireless sector;
- and
- when the number of wireless devices capable of inter-band carrier aggregation is greater than the number of wireless devices incapable of inter-band carrier aggregation, enabling usage of a low-frequency carrier as a primary component carrier for a carrier aggregation mode of operation.
