Abstract: Embodiments of the present invention pertain to optical wireless architecture. More particularly, certain embodiments of the invention pertain to a novel method and apparatus to generate millimeter-wave signals with simple and/or low cost architecture. Simple millimeter-wave generation and dispersion-tolerant transmission is based on photonic mixing of two free-running lightwaves and self-mixing down-conversion. More particularly, heterodyne mixing of two free run lightwaves is achieved, wherein one lightwave is modulated by an external modulator driven by electrical data as one of the side-bands of a millimeter-wave signal. Optical to electrical conversion is performed and the millimeter-wave signal is broadcasted by a high-frequency antenna to a receiving side having a local oscillator with self-mixing architecture to down-convert the radio frequency to its baseband form.

Abstract: A method and apparatus for generating sub-carriers is disclosed. Coherent optical sub-carriers with sub-carrier spacing are generated for carrying an orthogonal frequency division multiplexed (OFDM) signal. Multiple peaks are generated by cascading multiple phase modulators driven by different radio frequency sources.

Abstract: A wireless communication system includes a plurality of communication devices. The RF transceiver includes a transmitter and a plurality of receivers, each receiving signal from an associated communication device. An Enhanced Node B (eNB) can communicate with a plurality of communication devices in a Multiple-Input Multiple-Output (MIMO) system. The eNB includes a transmitter and plurality of antenna configured to transmit control information. The Reference Signal Received Power (RSRP) is the linear average over the power contributions (in[W]) of the resource elements that carry cell-specific reference signals within the considered measurement frequency bandwidth. The invention deals with swapping between cells in Radio Resource Management (RRM) Further Enhanced Non CA-based Inter-cell Interference Coordination (ICIC) for LTE measurement RSRP accuracy test cases.
