Patent ID: 8176340

Claim:
A method for managing communications between sub-systems of a communication device, the sub-systems of the communication device including a Baseband Integrated Circuit (BBIC) and a Radio Frequency Integrated Circuit (RFIC), the BBIC including a processing engine, a state machine module and an interface module, each of the BBIC and the RFIC including one or more Phase Locked Loops (PLLs), the method comprising: initializing a Digital Radio Frequency Third Generation (DigRF 3 G) interface between the RFIC and the BBIC, wherein the processing engine is functionally inactive during the initialization; exchanging one or more data packets between the RFIC and the BBIC based on the initialization of the DigRF3G interface; waking-up the processing engine after said initializing; and transferring the one or more data packets between the BBIC interface module and the processing engine.
