Abstract
Monitoring a MIMO pairing efficiency of a sector to determine whether or not to enable/disable inter-band carrier aggregation. If the pairing efficiency (whether predicted or actual) is high, inter-band carrier aggregation is disabled, and if the pairing efficiency is low, then inter-band carrier aggregation is enabled. The inter-band carrier aggregation utilizes a low-frequency carrier as a primary component carrier and a high-frequency carrier as a secondary component carrier. The MIMO mode of operation utilizes the high-frequency carrier for control transmissions.

A method for selecting between multiple-input-multiple-output (MIMO) and carrier aggregation modes of operation in a wireless network, the method comprising:
- monitoring a MIMO pairing efficiency of a sector in the wireless network;
- responsive to the MIMO pairing efficiency meeting a threshold, disabling inter-band carrier aggregation in the sector, the inter-band carrier aggregation utilizing a low-frequency carrier and a high-frequency carrier;
- and
- enabling the MIMO mode of operation in the sector, the MIMO mode of operation utilizing the high-frequency carrier.
A system for selecting between multiple-input-multiple-output (MIMO) and carrier aggregation modes of operation in a wireless network, the system comprising:
- a processing node;
- and
- a processor coupled to the processing node, the processor configured to perform operations comprising:
- determining that a predicted MIMO pairing efficiency of a sector in the wireless network meets a threshold, wherein inter-band carrier aggregation is enabled within the sector;
- responsive to determining that the predicted MIMO pairing efficiency meets the threshold, disabling inter-band carrier aggregation in the sector;
