Systems and methods for generating a discovery signal in a device-to-device or network communication
Patent number: 9203568Abstract: The techniques introduced here provide for device discovery of a greater number of mobile devices in a mobile network by increasing the multiplexing capacity of the system. The techniques may be applied to device-to-device communication networks and small cells using low power nodes (e.g., pico and femto eNodeB in a 3GPP LTE or LTE advanced network). Additionally, the techniques provide for mapping between a mobile device ID and an orthogonal resource of the discovery signal.Type: GrantFiled: September 27, 2013Date of Patent: December 1, 2015Assignee: Intel IP CorporationInventors: Seunghee Han, Jong-Kae Fwu, Youn Hyoung Youn Heo, Apostolos Papathanassiou, Hong He -

Patent number: 8325649Abstract: A method and apparatus are provided for determining a Transmission Power Control (TPC) command of an UpLink (UL) channel in a User Equipment (UE). The method includes storing TPC commands received through each Radio Link (RL) for preset combining periods, before entry into Discontinuous Transmission (DTX); combining the stored TPC commands; if all of the TPC commands are UP commands, determining a combined TPC command of the UL channel as a power level derived using a TPC command received in a designated previous DownLink (DL) slot among DL slots included in each RL, and controlling a transmit power of the UL channel, in a current DL slot which uplink transmission is resumed, using a power level corresponding to the determined TPC command.Type: GrantFiled: May 8, 2008Date of Patent: December 4, 2012Assignee: Samsung Electronics Co., LtdInventors: Gert-Jan Van Lieshout, Kundan Kumar Lucky, Pradeep Dwarakanath, Vinod Cherian Joseph, Youn Heo

Publication number: 20100254324Abstract: Determination of transmission power control commands in a UE by combining TPC commands received during DTX/DRX modes. The combining is done on those TPC commands which are received on different radio links after ignoring TPC commands which might be received in a DL slot overlapping with no UL transmission. The UE thus uses the combined TPC commands as derived at the time of entry into DTX for the second UL DPCCH preamble transmission which leads to increase in link reliability and subsequent conservation of power by the UE. The UE uses the same power as derived in the previous slot for resumption of transmission when all the TPC commands, received in the DL slot overlapping with no UL transmission, are UP. TPC commands for the transmission of the 2nd DPCCH preamble at transmission resumption is determined by combining stored TPC commands from each of the radio links that were received by the UE while entering into DTX gap and said TPC commands could not be applied with the newly received TPC commands.Type: ApplicationFiled: May 8, 2008Publication date: October 7, 2010Inventors: Gert-Jan Van Lieshout, Kundan Kumar Lucky, Pradeep Dwarakanath, Vinod Cherian Joseph, Youn Heo
