Abstract: Certain aspects of the present disclosure provide multi-way diversity receivers with multiple synthesizers. Such a multi-way diversity receiver may be implemented in a carrier aggregation (CA) transceiver. One example wireless reception diversity circuit generally includes three or more receive paths for processing received signals and two or more frequency synthesizing circuits configured to generate local oscillating signals to downconvert the received signals. Each of the frequency synthesizing circuits is shared by at most two of the receive paths, and each pair of the frequency synthesizing circuits may generate a pair of local oscillating signals having the same frequency.

Abstract: Aspects of a wireless apparatus for configuring a plurality of VCOs are provided. The apparatus may be a UE. The UE receives a configuration for a plurality of carriers. Each carrier corresponds to a different LO frequency. In addition, the UE determines a VCO frequency for generating each LO frequency. Further, the UE assigns each determined VCO frequency to each of a plurality of VCO modules based on a distance between the VCO modules and each of the determined VCO frequencies. The plurality of VCO modules are of a set of VCO modules including at least three VCO modules.
