Abstract
System, methods, and computer-readable media herein dynamically assign bands to primary and secondary component carriers for inter-carrier aggregation capable devices. In embodiments, an inter-carrier aggregation capable device is identified as being within a coverage area of a cell site component that is controlled by a base station. When the device is within a predefined distance of the cell site component, throughput of the device is analyzed. When the throughput indicates that the device is impacted by noise and/or interference at the cell site, the base station assigns a band to a primary component carrier based on the sector power ratio (SPR) of a corresponding antenna.
Claims19
A method comprising:
- determining that an inter-carrier aggregation capable device is within a predefined distance of a centralized geographic location corresponding to one or more of a large-scale component or a small-scale component of a cell site, wherein the predefined distance is associated with an increased likelihood of throughput degradation;
- monitoring, by a base station associated with the cell site, throughput of the inter-carrier aggregation capable device that is within the predefined distance of the cell site;
- determining, by the base station associated with the cell site, that the throughput of the inter-carrier aggregation capable device is at or below a threshold;
- determining that a sector power ratio (SPR) of a first band is lower than an SPR of other bands at the cell site prior to assigning the first band to a primary component carrier associated with the inter-carrier aggregation capable device;
- and
- subsequent to determining that the throughput of the inter-carrier aggregation capable device is at or below the threshold, assigning the first band to the primary component carrier associated with the inter-carrier aggregation capable device based on the SPR of the first band.
One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method comprising:
- determining a quantity of inter-carrier aggregation capable devices that are within a coverage area of a cell site;
- identifying at least one of the inter-carrier aggregation capable devices within the coverage area that is within a predefined distance of a centralized geographic location corresponding to one or more of a large-scale component or a small-scale component of the cell site, wherein the predefined distance is associated with an increased likelihood of throughput degradation;
- analyzing, by a base station associated with the cell site, throughput of the at least one inter-carrier aggregation capable device within the predefined distance;
- determining, by the base station associated with the cell site, that the throughput of the at least one inter-carrier aggregation capable device is at or below a threshold;
- determining that an SPR of a first band is lower than an SPR of other available bands at the cell site prior to assigning the first band to a primary component carrier associated with the at least one inter-carrier aggregation capable device;
- and
- subsequent to determining that the throughput of the at least one inter-carrier aggregation capable device is at or below the threshold, assigning the first band to the primary component carrier associated with the at least one inter-carrier aggregation capable device based at least on determining the SPR of the first band relative to the SPR of the other available bands at the cell site.
A system comprising:
- a base station associated with a cell site having multiple antennas, the cell site capable of communicating RF transmissions in at least a first carrier band and a second carrier band, the base station including a processor that:
- monitors the cell site to identify when an inter-carrier aggregation capable device enters a coverage area of the cell site;
- and
- each time an inter-carrier aggregation capable device enters the coverage area of the cell site, the processor:
- determines that the inter-carrier aggregation capable device is within a predefined distance of a centralized geographic location corresponding to one or more of a large-scale component or a small-scale component of the cell site, wherein the predefined distance is associated with an increased likelihood of throughput degradation;
- monitors throughput of the inter-carrier aggregation capable device;
- determines that an SPR of the first carrier band is lower than an SPR of a second carrier band at the cell site prior to assignment of the first carrier hand to a primary component carrier associated with the inter-carrier aggregation capable device;
- and
- subsequent to determining the throughput is at or below a threshold, assigns the first carrier band to the primary component carrier associated with the inter-carrier aggregation capable device based on determining the SPR of the first carrier band is-being less than the SPR of the second carrier band.
