Title:
COMPACT TRANSCEIVER ARCHITECTURE FOR ACHIEVING DEVICE TO DEVICE (D2D) COMMUNICATION USING UPLINK AND DOWNLINK CARRIER FREQUENCIES
Document Type and Number:
WIPO Patent Application WO/2013/130986
Kind Code:
A3
Abstract:
A system and method for device-to-device (D2D) communication is disclosed. A preferred embodiment comprises a frequency synthesizer configured to provide a first carrier frequency and a second carrier frequency, an up-converter coupled to the frequency synthesizer and configured to up-convert a first baseband signal into a cellular uplink signal when receiving the first carrier frequency from the frequency synthesizer, and configured to up-convert the first baseband signal into a first device-to-device signal when receiving the second carrier frequency from the frequency synthesizer, and a down-converter coupled to the frequency synthesizer and configured to down-convert a second device-to-device signal into a second baseband signal when receiving the first carrier frequency from the frequency synthesizer, and configured to down-convert a cellular downlink signal into the second baseband signal when receiving the second carrier frequency from the frequency synthesizer.
