Patent number: 8724634Abstract: Method and apparatus for receiving high speed downlink shared channel (HS-DSCH) transmissions are disclosed. An HS-DSCH medium access control (MAC-ehs) entity receives MAC-ehs protocol data units (PDUs) via a high speed downlink shared channel (HS-DSCH) while in one of Cell_FACH, Cell_PCH, and URA_PCH states. The reordering PDUs included in the MAC-ehs PDUs may be sent to a next processing entity without performing reordering of the PDUs. A certain reordering queue may enter a suspend state upon occurrence of a triggering event and MAC-ehs PDUs distributed to the reordering queue in the suspend state may be forwarded to the next processing entity without performing reordering. MAC-ehs reset procedure may be extended for a certain transmission such that the MAC-ehs reset is performed after receiving a MAC-ehs PDU in a target cell.Type: GrantFiled: March 14, 2008Date of Patent: May 13, 2014Assignee: InterDigital Technology CorporationInventors: Paul Marinier, Diana Pani, Christopher R. Cave, Rocco DiGirolamo, Stephen E. Terry

Patent number: 8724636Abstract: Downlink PDCCH is communicated in a manner that mitigates a UE from decoding the PDCCH on multiple aggregation levels. Ambiguous payload sizes are identified and modified through zero padding with one or more bits based on the payload size. Aggregation level scrambling sequences can be generated such that a receiving UE can accurately identify the aggregation level on which to decode the PDCCH. Indicator bits that signal the aggregation level to a UE can also be included in the PDCCH.Type: GrantFiled: March 30, 2009Date of Patent: May 13, 2014Assignee: QUALCOMM IncorporatedInventors: Wanshi Chen, Tao Luo, Juan Montojo, Peter Gaal

Patent number: 8724638Abstract: Methods and systems for selectively processing VLAN traffic from different networks while allowing flexible VLAN identifier assignment are disclosed. According to one aspect, a layer 2 switch includes a virtual switch identifier data structure that associates a VLAN identifier extracted from a layer 2 frame and a port identifier corresponding to a port on which a frame is received with a virtual switch identifier. The virtual switch identifier is used to select a per-virtual-switch data structure, such as a forwarding table. The per-virtual-switch data structure is used to control processing of the layer 2 frame on a per-virtual-switch basis. The per-virtual-switch data structure may also be updated separately from the data structures assigned to other virtual switches.Type: GrantFiled: April 5, 2010Date of Patent: May 13, 2014Assignee: Extreme Networks, Inc.Inventor: Susan E.

Patent number: 8724640Abstract: A method for operating a dezentralized communication network with network nodes is provided. The method is based on protocols in conventional peer-to-peer networks. The method provides rapid searching of resources whereby each network node manages a table containing information regarding all the other network nodes, such that a network that contains the resource is immediately retrieved among the table entries. Furthermore, the table contains device names of technical components on which the network nodes are mapped, so that a technical component is directly addressed also via its device name without use of the search process.Type: GrantFiled: August 27, 2008Date of Patent: May 13, 2014Assignee: Siemens AktiengesellschaftInventors: Christoph Gerdes, Claus Kern, Christian Kleegrewe, Sebnem Rusitschka, Alan Southall
