LO RX DYNAMIC LOCAL OSCILLATOR LO SCHEME AND SWITCHABLE RECEIVE RX CHAIN FOR CARRIER AGGREGATION

摘要

Certain aspects of the disclosure may dynamically adjust the voltage-controlled oscillator (VCO) frequency, local oscillator (LO) split ratio, and / or receive path when adding or interrupting the reception of a component carrier in a carrier aggregation The present invention provides methods and apparatus for modulating an input signal. Dynamic adjustment is utilized to avoid (or at least reduce) the VCO, LO, and to transmit signal coupling issues across multiple component carriers with minimal (or at least reduced) current consumption by the VCO and LO divider.;
