Patent number: 8638771Abstract: Techniques for transmitting data in a manner to support multi-user scheduling, multiple-input multiple-output (MIMO) transmission, and interference cancellation are described. A base station assigns multiple time segments of a transmission time interval (TTI) to at least one terminal, maps data for each terminal to at least one time segment assigned to the terminal, and spreads the data in each time segment with at least one channelization code used in the TTI. A terminal receives an assignment of at least one time segment from among multiple time segments of the TTI, obtains input samples for the at least one time segment, and despreads the input samples with the at least one channelization code used in the TTI.Type: GrantFiled: August 10, 2006Date of Patent: January 28, 2014Assignee: QUALCOMM IncorporatedInventors: Ivan Jesus Fernandez-Corbaton, Josef J.

Patent number: 8503517Abstract: A system is provided for transmitting information through a speech codec (in-band) such as found in a wireless communication network. A modulator transforms the data into a spectrally noise-like signal based on the mapping of a shaped pulse to predetermined positions within a modulation frame, and the signal is efficiently encoded by a speech codec. A synchronization sequence provides modulation frame timing at the receiver and is detected based on analysis of a correlation peak pattern. A request/response protocol provides reliable transfer of data using message redundancy, retransmission, and/or robust modulation modes dependent on the communication channel conditions.Type: GrantFiled: June 3, 2009Date of Patent: August 6, 2013Assignee: QUALCOMM IncorporatedInventors: Pengjun Huang, Christian Pietsch, Christian Sgraja, Georg Frank, Christoph A.

Patent number: 8155078Abstract: A method for using Internet mobility protocols with non Internet mobility protocols is described. A first gateway node communicates with a second gateway node using a first protocol. The first protocol is a non Internet mobility protocol. A home address (HoA) for a mobile node is managed by the second gateway node. Updates regarding the location of the mobile node within a domain are received using a second protocol. The second protocol is an Internet mobility protocol. Intra-domain mobility for the mobile node is managed by the second gateway node using the second protocol.Type: GrantFiled: October 10, 2007Date of Patent: April 10, 2012Assignee: QUALCOMM IncorporatedInventors: Kalle I. Ahmavaara, Vidya Narayanan, Wolfgang Granzow

Publication number: 20110274038Abstract: Methods and apparatuses are provided that facilitate avoiding establishment of unnecessary radio bearers in circuit switched fallback (CSFB). A CSFB procedure related to a device can be detected from receiving an extended service request or a forward relocation request, or from determining that an evolved packet system (EPS) is insufficient to handle a circuit switched voice call, and/or the like. Based at least in part on detecting the CSFB, establishment of radio bearers for inactive EPS bearers can be avoided. Where the device is in idle mode before CSFB, avoiding establishment of radio bearers can include avoiding establishment of all data radio bearers for the device.Type: ApplicationFiled: November 8, 2010Publication date: November 10, 2011Applicant: QUALCOMM INCORPORATEDInventors: Xipeng Zhu, Wolfgang Granzow

Patent number: 8014782Abstract: The present invention relates to improvements for a fast setup of physical communication channels in a CDMA-based communication system. A Node B of a telecommunication network is permitted to manage and assign a certain share of the downlink transmission resources of a radio network controller without inquiry of said radio network controller. On reception of a resource request message from a user equipment, the node B derives and specifies a certain amount of said resources that can be allocated to the user equipment. In a preferred embodiment of the present invention said resources are only assigned temporarily until the ordinary RL setup procedure, which involves the RNC, has been successfully finished.Type: GrantFiled: May 11, 2004Date of Patent: September 6, 2011Assignee: Telefonaktiebolaget L M Ericsson (PUBL)Inventors: Wolfgang Granzow, Georg Frank

Publication number: 20100322171Abstract: Methods, apparatus and computer program products are provided to improve the efficiency of resource allocation in wireless communication networks. In one provided embodiment, a wireless communication device determines a received signal strength of each of a number of signals received from a number of transmission sectors, provides first channel information for first signals including a signal having a highest received signal strength and signals having a received signal strength above a specified level relative to the highest received signal strength, provides second channel information for second signals including signals having a received signal strength below the specified level, and receives an allocation of one or more resource blocks from assigned transmission sectors based on a ranking of the first channel information, whereby the one or more resource blocks are reallocated to another wireless communication device, from another transmission sector, based on the second channel information.Type: ApplicationFiled: June 16, 2010Publication date: December 23, 2010Applicant: QUALCOMM IncorporatedInventors: Armin Dekorsy, Wolfgang Granzow, Lu Zhao, Stefan Brueck

Publication number: 20090016300Abstract: Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.Type: ApplicationFiled: June 17, 2008Publication date: January 15, 2009Applicant: QUALCOMM IncorporatedInventors: Kalle I.

Patent number: 7212823Abstract: In a synchronization scheme, for example for establishing a channel in a UMTS radio communication system, when a user device (or user equipment, UE) such as a mobile terminal is establishing a channel with a network, the user device transmits signals on the uplink DPCCH, and the power of these signals is ramped up from a calculated initial power level until the transmission is detected by the receiver, i.e. until the receiver has obtained synchronization to the uplink signal.Type: GrantFiled: November 13, 2002Date of Patent: May 1, 2007Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Wolfgang Granzow, Georg Frank, Dirk Gerstenberger
