Patent number: 9794798Abstract: A leaky repeater access node (LRAN) includes a first directional antenna and a second directional antenna to transmit and receive signals in at least one first frequency band, and a third antenna to transmit and receive signals in a second frequency band. The LRAN also includes first analog components to split a first signal received by the first directional antenna into a first portion and a second portion. The first analog components amplify the first portion and provide the amplified first portion to the second directional antenna. The first analog components also convert the second portion to the second frequency band and provide the converted second portion to the third antenna.Type: GrantFiled: December 29, 2014Date of Patent: October 17, 2017Assignees: Alcatel Lucent, Alcatel-Lucent USA Inc.Inventors: Michael G. Zierdt, Simone Maier, Andreas Pascht, Dmitry Chizhik

Publication number: 20160285534Abstract: In certain embodiments, a frequency-division duplexing (FDD) communication system has (i) a multiple in, multiple-out (MIMO) node with multiple MIMO-node antennas and (ii) a second node (e.g., a relay or a repeater) with at least one second-node antenna. The MIMO node transmits downlink (DL) signals to the second node over multiple DL channels in a DL frequency band (FB), and the second node transmits uplink (UL) signals to the MIMO node over multiple UL channels in a UL FB different from the DL FB. The MIMO node receives pilot signals from the second node in the UL and DL FBs and generates UL and DL FB channel state information (CSI) based on the received pilot signals. The MIMO node decodes UL data signals from the second node based on the UL FB CSI and generating DL data signals to the second node based on the DL FB CSI.Type: ApplicationFiled: March 27, 2015Publication date: September 29, 2016Inventors: Li Erran Li, Michael G.

Patent number: 8843098Abstract: The present invention provides a filter that may be used as a reconstruction filter with a built-in balun. One embodiment of the filter includes first and second input nodes for receiving balanced radiofrequency signals and an inductive-capacitive (LC) circuit coupled between the first and second input nodes and first and second intermediate nodes. This embodiment of the filter also includes a coupling circuit that couples the first and second intermediate nodes to an output node. Balanced signals within a filter bandwidth are transmitted from the first and second input nodes to the output node and balanced signals outside the filter bandwidth are substantially shorted to ground.Type: GrantFiled: June 10, 2011Date of Patent: September 23, 2014Assignee: Alcatel LucentInventor: Michael G. Zierdt

Patent number: 8143746Abstract: In one embodiment, a wireless power transfer system has a wireless power transmitter and receiver. The transmitter has a transmitting resonant circuit that resonates at a first frequency and a signal generator that generates a signal at a second frequency. The transmitter also has a power detector that measures reflected power at the transmitting resonant circuit, and an auto-tuner that generates transmitter tuning parameters for adjusting the first and second frequencies to reduce reflected power. The receiver has a receiving resonant circuit that resonates at a third frequency based on a receiver tuning parameter. The receiver tuning parameter is generated by a power detector that measures power generated at the receiving resonant circuit, and an auto-tuner that generates the receiver tuning parameter to increase the load power.Type: GrantFiled: December 21, 2009Date of Patent: March 27, 2012Assignee: Alcatel LucentInventors: Thomas L.
