Patent number: 9313672Abstract: A method for coordinated transmission in a plurality of cells of a wireless communication system, wherein a user equipment triggers coordinate transmission of a plurality of cells if it detects an interference condition between signals received by the plurality of cells, the user equipment detecting the interference condition based on a radio quality metric dynamically set by the network and triggering coordinate transmission by transmitting a trigger signal to at least a cell of the plurality of cells. A radio equipment and a user equipment for use in a wireless communication system can implement coordinated transmission with the method.Type: GrantFiled: December 20, 2010Date of Patent: April 12, 2016Assignee: TELECOM ITALIA S.p.A.Inventors: Marco Caretti, Valeria D'Amico, Bruno Melis, Dario Sabella

Patent number: 9001803Abstract: A system for processing an RF signal received via a plurality of antenna elements includes a connection arrangement for selecting a sub-set of a given number of RF signals received from the antenna elements as well as a processing arrangement for combining the received RF signals of the selected sub-set into a single RF signal for demodulation. The system includes an RF phasing circuit for producing selective combinations of the received RF signals by applying relative RF phase shift weights to the RF signals that are combined; each combination includes RF signals received from a number of adjacent antenna elements equal to the number of the RF signals in the sub-set to be selected. A radio performance estimator generates for each selective combination of RF signals at least one non-RF radio performance indicator representative of the quality of the RF signals in the combination.Type: GrantFiled: December 19, 2007Date of Patent: April 7, 2015Assignees: Telecom Italia S.p.A., Advanced Digital Broadcast S.A.Inventors: Loris Bollea, Valeria D'Amico, Maurizio Fodrini, Paolo Gallo, Bruno Melis, Alfredo Ruscitto

Patent number: 8345789Abstract: In a communication system, such as a Multiple Input Multiple Output system operating in a spatial multiplexing mode, for use, e.g., in a WLAN or HSPDA device, a plurality of information flows are received via a set of receive antennas by deriving from at least some, and possibly all, of the receive antennas, respective RF signals, and producing from the RF signals thus derived, a plurality of receive signals, each receive signal to be demodulated to recover one of the information flows transmitted. The receive signals are produced as combinations of the RF signals having applied thereto relative RF phase shift weights.Type: GrantFiled: December 19, 2007Date of Patent: January 1, 2013Assignees: Telecom Italia S.p.A., Pirelli & C.

Patent number: 7606334Abstract: A system for estimating the transfer function of a transmission channel such as the downlink channel in a CDMA system over which a pilot signal and a data signal are transmitted. The system includes at least one estimator for producing first and second channel estimates from the pilot signal and the data signals and a combination node for combining the first and second channel estimates to obtain final combined channel estimates. The system includes an interpolator module adapted for interpolating the second channel estimates over a basic estimation reference time to produce equal numbers of channel estimates over the basic estimation reference time derived from the data signal and the pilot signal respectively, and possibly rate adaptation modules adapted for mapping the channel estimates on the basic estimation reference time. The combination node is a summation node producing the final combined channel estimates as a sum of the first channel estimates and the interpolated second channel estimates.Type: GrantFiled: September 30, 2003Date of Patent: October 20, 2009Assignee: Telecom Italia S.p.A.Inventors: Valeria D'Amico, Maurizio Graziano, Bruno Melis, Alfredo Ruscitto
