Abstract
A method for performing Carrier Aggregation (CA) using spectrum shared between an incumbent user and a telecommunications network includes establishing a primary cell (PCell) for the secondary user in a portion of radio spectrum that is exclusively licensed to the telecommunications network, establishing a secondary cell (SCell) for the telecommunications network in a portion of the shared spectrum that is shared with the incumbent user, receiving schedule data for the incumbent user at a controller in communication with the incumbent user and a transmitter for the PCell and the SCell, scheduling transmissions for the PCell and the SCell to avoid interference to the incumbent user, and transmitting the scheduled transmissions through the PCell and the SCell using Carrier Aggregation (CA). Accordingly, one or more SCell in shared spectrum may be aggregated with a PCell in dedicated spectrum.
