Claim Text:
1. A method for controlling gain in a multi-carrier wireless device, the method comprising: estimating or measuring, by the wireless device, indications of received signal quality for at least two aggregated component carriers (CCs) in a same radio frequency band, the at least two aggregated CCs comprising a primary component carrier (PCC) and one or more secondary component carriers (SCCs); determining, based on indications of received signal quality of the PCC, a primary estimate indicating a signal quality of the PCC alone; determining, based on indications of received signal quality of one or more SCCs, a secondary estimate indicating a signal quality of the one or more SCCs; when the primary estimate is greater than or approximately the same as the secondary estimate, determining a common gain for the at least two aggregated CCs using a first function; when the primary estimate is less than the secondary estimate, determining the common gain for the at least two aggregated CCs using a second function, wherein the second function comprises a linear combination of PCC received signal power and a signal power of one or more of the SCCs; and applying the common gain to received signals of the at least two aggregated CCs to obtain adjusted received signals.
