Patent number: 9451601Abstract: Method and apparatus for multiplexing data for multiple wireless transmit/receive units (WTRUs) for high speed downlink channels are disclosed. A WTRU may receive a joint high speed shared control channel (HS-SCCH) including a common part and WTRU-specific parts. The common part includes common control information for WTRUs multiplexed in one transmission time interval (TTI), and each of the WTRU-specific parts includes WTRU-specific control information for a corresponding WTRU. The WTRU receives a high speed physical downlink shared channel (HS-PDSCH) based on decoding on the joint HS-SCCH. The HS-SCCH may include a group WTRU identity shared by a group of WTRUs.Type: GrantFiled: May 2, 2011Date of Patent: September 20, 2016Assignee: InterDigital Patent Holdings, Inc.Inventors: Diana Pani, Benoit Pelletier, Sylvie Gomes, Christopher R.

Patent number: 9444531Abstract: A transmitter generates and transmits a low rate signal to its intended receiver. Upon receiving the low rate signal, the intended receiver generates and transmits a channel sounding response (CSR), said CSR being a short burst having a predefined transmit format and carrying predetermined information. The transmitter then analyzes the CSR and determines uplink channel response, estimates downlink channel response, and determines appropriate transmit parameter settings based on the analysis and downlink response estimate. Adjustment of the transmit parameters can be made in either the MAC or PHY layer or in a combination of both. After adjusting its transmit parameters and modulating sub-carriers with user-data according to the determined transmit settings, the transmitter transmits the user-data to the receiver on a preferred portion of bandwidth.Type: GrantFiled: December 7, 2015Date of Patent: September 13, 2016Assignee: InterDigital Technology CorporationInventor: Joseph S.

Patent number: 9426756Abstract: Method and apparatus are disclosed for determining a physical uplink power level for transmissions on a physical uplink channel. In one embodiment, a random access channel (RACH) uplink message is transmitted. The RACH uplink message includes a RACH message power level and/or a downlink pathloss figure. A downlink message including a power offset value is received. The physical uplink power level is set for transmissions on the physical uplink channel based on the power offset value. In another embodiment, a RACH uplink message is transmitted and a downlink message including a relative power offset value is received. The physical uplink power level for transmissions on the physical uplink channel is then set based on the relative power off set value.Type: GrantFiled: March 12, 2014Date of Patent: August 23, 2016Assignee: InterDigital Patent Holdings, Inc.Inventors: Jin Wang, Joseph S. Levy, Stephen E. Terry, Ulises Olvera-Hernandez, Shankar Somasundaram

Patent number: 9426752Abstract: A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.Type: GrantFiled: October 4, 2012Date of Patent: August 23, 2016Assignee: InterDigital Patent Holdings, Inc.Inventors: Guodong Zhang, Erdem Bala, Philip J.

Publication number: 20160219568Abstract: A method and an apparatus for transmitting pilots on multiple antennas are disclosed. A wireless transmit/receive unit (WTRU) may transmit a primary dedicated physical control channel (DPCCH) and at least one secondary DPCCH via multiple antennas using different channelization codes. When a required transmit power exceeds a maximum allowed transmit power of the WTRU, power scaling may be applied equally to the primary DPCCH and the secondary DPCCH, such that a power ratio between the primary DPCCH and the secondary DPCCH remains the same before scaling as after scaling. The secondary DPCCH may include a same number of pilot bits as the primary DPCCH both in a normal mode and in a compressed mode, respectively. The same total pilot energy ratio may be maintained between the primary DPCCH and the secondary DPCCH both in a normal mode and in a compressed mode, respectively.Type: ApplicationFiled: January 22, 2016Publication date: July 28, 2016Applicant: InterDigital Patent Holdings, Inc.Inventors: Benoit Pelletier, Lujing Cai, Hong O.

Publication number: 20150373572Abstract: Techniques may be used for interference measurement and management in directional mesh networks, including centralized and/or distributed approaches. A centralized node, such as an operations and maintenance (OAM) center, may use feedback from nodes in the mesh network to partition the nodes in the mesh network into clusters based on interference levels. Interference measurement reports may be used by the centralized node to update cluster membership. An initiating node in the mesh network may use topographical information to generate an initial interference cluster, and interference measurement frame (IMF) scheduling information may be used to schedule transmissions within the interference clusters. Techniques for opportunistic measurement campaigns, simultaneous measurement campaigns, link failure detection, and link re-acquisition in directional mesh networks may also be used.Type: ApplicationFiled: February 5, 2014Publication date: December 24, 2015Applicant: InterDigital Patent Holdings, Inc.Inventors: Onur SAHIN, Arnab ROY, Yugeswar DEENOO, Ravikumar V.
