Abstract:
1. A method for improving reception by a carrier aggregation capable wireless communication device comprising a first radio frequency (RF) chain and a second RF chain configurable to support aggregation of multiple component carriers on a carrier aggregation capable network, the method comprising the wireless communication device: using the first RF chain to support a connection to the carrier aggregation capable network via a first frequency band; determining that a signal quality of a signal received by the first RF chain has degraded below a threshold signal quality; tuning the second RF chain to a second frequency band, the second RF chain not being actively used for carrier aggregation; measuring, via the second RF chain, a signal characteristic of the second frequency band while the second RF chain is not being actively used for carrier aggregation in response to the signal quality of the signal received by the first RF chain degrading below the threshold signal quality; and adjusting a configuration of the first RF chain based at least in part on the measured signal characteristic.
