Abstract
Embodiments of techniques for low-cost multimode operation in wireless communications involving the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) standard and the Global System for Mobile telecommunications (GSM) standard are described. In one aspect, a method of multimode operation in a mobile telecommunication device renders wireless communications based on the TD-SCDMA standard using either or both of first and second frequency synthesizers of the mobile telecommunication device. The method also receives signals based on the GSM standard using either or both of the first and second frequency synthesizers of the mobile telecommunication device. Techniques for performing baton handover as well as signal reception for multimedia broadcast and multicast services (MBMS) using two frequency synthesizers are also provided.
