Title:
METHOD AND APPARATUS FOR CONCURRENT COMMUNICATION WITH MULTIPLE WIRELESS COMMUNICATION SYSTEMS OF DIFFERENT RADIO ACCESS TECHNOLOGIES
Document Type and Number:
WIPO Patent Application WO/2014/204706
Kind Code:
A3
Abstract:
A wireless device supporting concurrent communication with multiple wireless systems of different radio access technologies (RATs) are disclosed. In an exemplary design, an apparatus includes first and second receivers supporting concurrent signal reception from wireless systems of different RATs. The first receiver receives a first downlink signal from a first wireless system of a first RAT. The second receiver receives a second downlink signal from a second wireless system of a second RAT, which is different from the first RAT. The first and second receivers may operate concurrently. The second receiver may be broadband and/or may support carrier aggregation. The apparatus may further include first and second local oscillator (LO) generators to generate LO signals for the first and second receivers, respectively, based on different divider ratios in order to mitigate voltage controlled oscillator (VCO) pulling.
