Publication number: 20160150573Abstract: Method and apparatus are disclosed for optimizing Random Access Channel (RACH) transmissions from wireless transmit/receive units (WTRUs) for multiple transmissions. A WTRU may initiate uplink transmission for a random access procedure using a configured time resource such that the uplink resources may be time shared by a plurality of WTRUs. The transmission time may be calculated on an absolute or relative basis. A backoff time may be applied before starting the uplink transmission. The backoff time may be WTRU-specific, WTRU group-specific, specified per access class and may be determined based on a priority basis. A scaling factor may be applied to the backoff time. A contention free allocation method may be used to determine the appropriate resource. The data may be transmitted with and without a preamble. The WTRUs may include machine type communication devices and may be grouped in accordance with a number of factors or characteristics.Type: ApplicationFiled: February 1, 2016Publication date: May 26, 2016Applicant: InterDigital Patent Holdings, Inc.Inventors: Diana Pani, Sylvie Gomes, Bhaskar M.

Patent number: 9301225Abstract: A wireless transmit/receive unit (WTRU) in communication with a wireless network that may include a base station (or base node) and a cell that may be in a dormant mode is contemplated. The WTRU may determine that the WTRU may be within a vicinity of the cell and may generate a report that includes one or more measurements related to a location of the WTRU. The WTRU may transmit the report to the network and may receive an indication to perform one or more measurements related to the cell. The one or more measurements related to the cell may be based on a Common Pilot Channel (CPICH), a Synchronization Channel (SCH), and/or a Broadcast Channel (Primary Common Control Physical Channel) (BCH P-CCPCH) that may be transmitted by the cell upon a command from a base node.Type: GrantFiled: January 7, 2011Date of Patent: March 29, 2016Assignee: InterDigital Patent Holdings, Inc.Inventors: Virgil Comsa, Diana Pani, Joseph S.

Publication number: 20150163690Abstract: Methods and apparatus are disclosed for a wireless transmit/receive unit (WTRU) to detect and perform measurements with respect to Home Node-Bs (HNB) and Home evolved Node-Bs (H(e)NB) (collectively “HNB”). The methods may include generating and transmitting a request for a measurement configuration that may include gap allocations to detect and measure a primary scrambling code or a physical cell identity of a target HNB for at least one frequency or radio access technology (RAT). The request may be in response to the WTRU entering a HNB cell for which the WTRU has stored fingerprint information and whose closed subscriber group ID is in the WTRU's whitelist. The network may configure the WTRU to measure the requested frequency or RAT in response to the proximity report/request. Methods are described for releasing the measurement configuration.Type: ApplicationFiled: February 19, 2015Publication date: June 11, 2015Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Diana Pani, Paul Marinier, Sylvie Gomes

Publication number: 20130188503Abstract: Mobility states are defined in order to prevent excess signaling overhead and to conserve power on a wireless transmit/receive unit (WTRU) in a wireless network. The WTRU may determine that is operating in a low mobility state based on triggers related to the frequency of movement of the WTRU between network cells. The WTRU may change cells less frequently in a low or no mobility state than in a normal mobility state. Upon determining that the WTRU is in the low or no mobility state, the WTRU may configure mobility procedures associated with the low or no mobility state in order to conserve power and other network resources. The WTRU may coordinate its mobility state with the network.Type: ApplicationFiled: April 1, 2011Publication date: July 25, 2013Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Bhaskar Anepu, Diana Pani, Christopher Cave, Sylvie Gomes
