A preamble selected from a specific preamble group is transmitted. A random access response message having a Transmission Time Interval (TTI) bundling indicator is awaited in response to the preamble. A combined message generated by applying a TTI bundling based on the TTI bundling indicator with a number of TTIs is transmitted, when the random access response message is received.Type: GrantFiled: April 29, 2010Date of Patent: January 13, 2015Assignee: Samsung Electronics Co., LtdInventor: Kyeong In Jeong

Patent number: 8934377Abstract: Systems and methods described herein are directed to solutions for Network on Chip (NoC) interconnects that supports reconfigurability to support a variety of different traffic profiles each having different sets of traffic flows after the NoC is designed and deployed in a SoC. Reconfiguration of the NoC to map and load a new traffic profile or change the currently mapped traffic profile is performed by an external optimization module which maps various transactions of a given traffic profile to the NoC and reconfigure the NoC hardware by loading the computed mapping information. As part of the mapping process, load balancing between NoC layers may be performed by automatically assigning the transactions in the traffic profile to be routed over certain NoC layers and channels, automatically determining the routes based on the bandwidth requirements of the transaction. The deadlock avoidance and isolation properties of various transactions are maintained during the mapping.Type: GrantFiled: March 11, 2013Date of Patent: January 13, 2015Assignee: NetSpeed SystemsInventors: Sailesh Kumar, Eric Norige

Patent number: 8934457Abstract: A method and apparatus for interference suppression in wireless communication systems, especially Orthogonal Frequency Division Multiplexed (OFDM) systems, is presented. The array apparatus includes a two-tier adaptive array system, which provides for both spatial diversity and beamforming at the uplink and includes sub-arrays spaced at a distance sufficient to provide spatial diversity and support beamforming or scanning. A Direction of Arrival (DOA) of signals impinging upon the array can be calculated by comparing signals from sub-array elements. Each sub-array can be filtered or beamformed to provide high gain to desired signals received from the DOA (which may be a multipath signal) while simultaneously dampening-out undesired signals, such as co-channel interference (CCI) in the frequency band of operation. The DOA is also used for allocating frequency bins for data signals, such as in an OFDM system, to provide weighted guidelines for bin allocation to maximize received signal power.Type: GrantFiled: October 7, 2011Date of Patent: January 13, 2015Assignee: Tellabs Operations, Inc.Inventors: Samir Kapoor, Daniel J.

Patent number: 8934423Abstract: A central resource manager is communicatively coupled to a broadcast/multicast service (BMS) capable system. The BMS capable system has a radio access network that includes at least one BMS service area and a total number of BMS bearers for transporting media streams. Each BMS service area has associated therewith a portion of the total number of BMS bearers. The central resource manager allocates, to a first local call controller of a plurality of local call controllers, a first portion of the total number of BMS bearers to be managed locally by the first local call controller, and identifies the first portion of the total number of BMS bearer to the first local call controller. The central resource manager also manages a second portion of the total number of BMS bearers for a subsequent allocation to at least one local call controller of the plurality of local call controllers.Type: GrantFiled: September 13, 2011Date of Patent: January 13, 2015Assignee: Motorola Solutions, Inc.Inventors: Donald G. Newberg, Peter M. Drozt, Michael F. Korus

Patent number: 8934374Abstract: Some embodiments provide a capacity management agent that modifies content requests to adjust bandwidth consumption when streaming requested content from a content provider to a requesting user. The modifications include modifying a URL or header information of the request. The agent performs a process that receives a request for content of a content provider. The process identifies a parameter of the carrier network and modifies the request when the parameter satisfies a threshold. The process passes the request to the content provider and the content provider provides content that consumes a first set of resources in response to an unmodified request and a second set of resources in response to a modified request. When the parameter identifies congestion, the first set of resources is greater than the second set of resources. When the condition parameter identifies underutilization, the first set of resources is less than the second set of resources.Type: GrantFiled: May 15, 2013Date of Patent: January 13, 2015Assignee: Edgecast Networks, Inc.Inventors: Andrew Lientz, Jayson G.

Patent number: 8929255Abstract: A network switch includes a first network port, a second network port, and a port virtualization module associated with the first network port. The port virtualization module determines that a device coupled to the first network port includes a first virtual network interface and provides a second virtual network interface on the first network port. The second virtual network interface is associated with the first virtual network interface. The network switch provides an aggregation zone including the second network port, the first virtual network interface, and the second virtual network interface.Type: GrantFiled: December 20, 2011Date of Patent: January 6, 2015Assignee: Dell Products, LPInventors: Hendrich M. Hernandez, Gaurav Chawla, Robert L. Winter

Patent number: 8929397Abstract: A transmitter device includes a controller configured to generate a first field and a second field. The first field is at least one of a packet synchronization information field or a frame boundary indication field, the second field is a channel estimation field starting after the first field ends. The controller is configured to generate the second field at least in part by generating a first channel estimation sequence (CES) symbol and a second CES symbol. At least one of i) a sequence in the first field serves as a cyclic prefix of the first CES symbol, ii) a beginning portion of the second CES symbol serves as a cyclic postfix of the first CES symbol, or iii) an ending portion of the first CES symbol serves as a cyclic prefix of the second CES symbol.Type: GrantFiled: May 7, 2012Date of Patent: January 6, 2015Assignee: Marvell World Trade Ltd.Inventors: Hongyuan Zhang, Rohit U.

Patent number: 8929390Abstract: In a method for estimating a channel at a receiver in a wireless communications network, the receiver obtains channel model parameters for a received signal based on raw channel estimates for the received signal, where each raw channel estimate corresponds to an antenna at the receiver. The receiver combines, for each of a plurality of contiguous subcarriers in the wireless communications network, the channel model parameters to generate a first plurality of combined channel model parameters. The receiver then chooses a first set of indices corresponding to combined channel model parameters from among the first plurality of combined channel model parameters having magnitudes passing a combined channel model parameter threshold. The receiver then estimates the channel in a sparse domain based on the first set of indices.Type: GrantFiled: September 24, 2012Date of Patent: January 6, 2015Assignee: Alcatel LucentInventors: Jonathan Ling, Dmitry Chizhik
