FRONT END CONFIGURATIONS SUPPORTING INTER-BAND CARRIER AGGREGATION

摘要

A method and apparatus support carrier aggregation. The apparatus includes a first antenna configured to transmit or receive signals in both a first high frequency band and a first low frequency band and a second antenna configured to transmit or receive signals in both a second high frequency band and a second low frequency band. At least one of the first high frequency band and the second high frequency band or the first low frequency band and the second low frequency band are different frequency bands for carrier aggregation. The apparatus may also include a third antenna and a multiband filter. The third antenna may be configured to receive signals in both the first and second high frequency bands or both the first and second low frequency bands. The multiband filter may be configured to filter the signals received by the third antenna.
