Abstract
A computing unit includes a processing module, a baseband processing module, and a RF section. In a femtocell AP mode, the processing module performs at least a portion of a MAC function to facilitate signal conversion between radio interface (RI) signals and PHY AP signals. The baseband processing module converts signals between the PHY AP signals and AP symbol stream. The RF section converts signals between the AP symbol streams and RF AP signals. In a cellular (CELL) mode, the processing module facilitates conversions between data and PHY CELL signals. The baseband processing module converts signals between PHY CELL signals and CELL symbol streams. The RF section converts signals between CELL symbol streams and RF CELL signals.
