Abstract
A method of operating a communication system includes communicating data between an access node and a wireless device using carrier aggregation. This carrier aggregation includes communicating using at least a primary carrier and a secondary carrier. The communication system determines that conditions for the secondary carrier meet a beamforming requirement criteria. The communication system determines an angle of arrival of the primary carrier. Based on the angle of arrival determined for the primary carrier, beamforming is applied to the secondary carrier.
