Abstract: Certain aspects of the present disclosure provide methods and apparatus for dynamically secondary cell (SCELL) allocation and frequency planning for carrier aggregation. One example system for radio frequency (RF) signal processing, generally includes a first integrated circuit (IC) comprising two or more receive chains, each receive chain for processing one of multiple component carriers in a carrier aggregation (CA) signal, wherein the first IC is configured to downconvert a signal associated with a primary cell of the CA signal; and a second IC configured to downconvert one or more signals associated with one or more secondary cells of the CA signal. The second IC may also be configured to upconvert a signal having a frequency different than the primary cell by an offset associated with the primary cell.
