Publication number: 20240235740Abstract: Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.Type: ApplicationFiled: March 26, 2024Publication date: July 11, 2024Applicant: InterDigital Patent Holdings, Inc.Inventors: Marian Rudolf, Paul Marinier, Diana Pani, Ghyslain Pelletier, Christopher R.

Patent number: 12035195Abstract: A method and base station are disclosed. The base station comprises a transceiver and a processor. The base station transmits a system information block (SIB) to a wireless transmit/receive unit (WTRU), wherein the SIB indicates random access transmission uplink resources. After transmitting the SIB, the base station receives a random access preamble from the WTRU. After receiving the random access preamble, the base station receives, using one or more of the uplink resources indicated by the SIB, a first message from the WTRU, wherein the first message includes a first radio network temporary identifier (RNTI) of the WTRU. After receiving the first message, the base station transmits a second message to the WTRU, wherein the second message is derived from a second RNTI, the second RNTI being different than the first RNTI. The base station may be configured to communicate with the WTRU on a plurality of cells.Type: GrantFiled: November 16, 2020Date of Patent: July 9, 2024Assignee: Pantech Wireless, LLCInventors: Diana Pani, Rocco DiGirolamo, Christopher R.

Publication number: 20240171489Abstract: Systems and methods are contemplated for reconfiguration of one or more MAC instances while the WTRU is operating using dual- or multi-MAC instance connectivity. For example, upon reception of RRC reconfiguration information that modifies one or more secondary MAC instances, the WTRU may transmit a reconfiguration complete message to a Macro eNB (MeNB) and may synchronize to small-cell or secondary eNB (SeNB), for example if triggered by one or more of an RRC flag, a physical downlink control channel (PDCCH) order (MeNB/SeNB), MAC activation information, etc. For example, the WTRU may synchronize to the SeNB for specific type(s) of RRC reconfigurations, but not other type(s) of RRC reconfigurations. Although examples may be described in terms of dual connectivity, the WTRU may establish connectivity and perform mobility procedures with more than two radio access network (RAN) nodes (e.g., eNBs), and the embodiments described may be equally applicable to those scenarios.Type: ApplicationFiled: January 29, 2024Publication date: May 23, 2024Applicant: InterDigital Patent Holdings, Inc.Inventors: Ghyslain Pelletier, Paul Marinier, Diana Pani

Publication number: 20240129841Abstract: Cell detection information, such as cell identity, frequency, dormant/active mode, etc. may be determined. This cell detection information may be reported based on properties of a received Auxiliary Synchronization Signal (AuSS) or discovery signal. The received signal may be processed as a function of its timing, for example, with respect to timing of a serving cell. A WTRU may obtain cell detection information for a neighbor cell. A cell may also be detected by surrounding WTRUs. A WTRU may determine timing of cell reactivation from a detected property of the AuSS or discovery signal. A WTRU may trigger an RRC procedure upon selecting a dormant but temporarily reactivated cell. An eNB may transmit AuSS for a dormant cell based on detection of signals received from neighbor cells. Quasi-colocation (QCL) demodulation may be performed based on the detected signal. The on/off state of a cell may be indicated.Type: ApplicationFiled: December 5, 2023Publication date: April 18, 2024Applicant: InterDigital Patent Holdings, Inc.Inventors: Paul Marinier, Ghyslain Pelletier, J.
