Publication number: 20110019776Abstract: A method and apparatus are described for obtaining port index information. In one scenario, downlink (DL) control information (DCI) is received that includes new data indicator (NDI). The NDI has a value indicating an antenna port for single-port transmission. In response to receiving the DCI, a single-port transmission associated with the indicated antenna port is received. The NDI may be associated with a disabled codeword and the DCI may include a second NDI. The DCI may be received over a physical downlink control channel (PDCCH). The DCI may include a resource block (RB) assignment information field (IF), a hybrid automatic repeat request (HARQ) process identity (ID) IF, a transmit power control (TPC) IF and, for each of a plurality of transport blocks, a modulation and coding scheme (MCS), an NDI and a redundancy version (RV).Type: ApplicationFiled: July 22, 2010Publication date: January 27, 2011Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Guodong Zhang, Afshin Haghighat, David S.

Patent number: 7630690Abstract: A Node-B/base station has an access burst detector. The access burst detector comprises at least one antenna for receiving signals from users and a pool of reconfigurable correlators. Each correlator correlates an inputted access burst code at an inputted code phase with an inputted antenna output. An antenna controller selectively couples any output of the at least one antenna to an input of any of the correlators. A code controller provides to an input of each correlator an access burst code. The code controller controls the inputted code phase of each controller. A sorter/post processor sorts output energy levels of the correlators.Type: GrantFiled: April 11, 2003Date of Patent: December 8, 2009Assignee: InterDigital Technology Corp.Inventors: John David Kaewell, Jr., Timothy Berghuis, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward L.

Patent number: 7092432Abstract: A Node-B/base station receiver comprises at least one antenna for receiving signals. Each finger of a pool of reconfigurable Rake fingers recovers a multipath component of a user and is assigned a code of the user, a code phase of the multipath component and an antenna of the at least one antenna. An antenna/Rake finger pool interface provides each finger of the Rake pool an output of the antenna assigned to that Rake finger. A combiner combines the recovered multipath components for a user to produce data of the user.Type: GrantFiled: May 4, 2004Date of Patent: August 15, 2006Assignee: InterDigital Technology CorporationInventors: John David Kaewell, Jr., Timothy Berghius, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward Hepler, Michael Koch, William C.

Patent number: 7082286Abstract: A Node-B/base station has a path searcher and at least one antenna for receiving signals from users. The path searcher comprises a set of correlators. Each correlator correlates an inputted user code with an inputted antenna output of the at least one antenna. An antenna controller selectively couples any output of the at least one antenna to an input of each correlator of the set of correlators. A code phase controller selects a user code for input into the set of correlators. Each delay of a series of delays delays the selected user code by a predetermined amount and each correlator of the set of correlators receives a different code phase delay of the selected user code. A sorter and path selector sorts the output energy levels of each correlator of the sets of correlators and produces a path profile for a user based on the sorted output energy levels.Type: GrantFiled: April 11, 2003Date of Patent: July 25, 2006Assignee: InterDigital Technology CorporationInventors: John David Kaewell, Jr., Timothy Berghuis, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward L.
