Patent number: 12388503Abstract: A WTRU may be configured to transmit to a network (e.g., in a first indication) a full power uplink transmission capability associated with the WTRU, e.g., Cap3. The WTRU may receive (e.g., in a second indication) an indication of whether the WTRU is allowed to operate with full power transmission. The WTRU may determine (e.g., from a set of TPMIs), a subset of TPMIs based on, for example, the WTRU's full power uplink transmission capability (e.g., where the subset of TPMIs includes a first TPMI). The set of TPMIs may comprise one or more subsets of TPMIs. The WTRU may transmit (e.g., in a third indication) an indication of the determined subset of TPMIs. The WTRU may receive (e.g., in a fourth indication) an indication of the first TPMI in the subset of TPMIs. The WTRU may transmit to the network uplink data precoded with the first TPMI.Type: GrantFiled: February 11, 2020Date of Patent: August 12, 2025Assignee: InterDigital Patent Holdings, Inc.Inventors: Afshin Haghighat, Virgil Comsa, Janet A.

Publication number: 20250234340Abstract: Systems, methods, and instrumentalities are described herein for adaptive waveform selection for wireless communication. In examples, the wireless transmit/receive unit (WTRU) may be configured with the orthogonal frequency-division multiplexing (OFDM) initially. If the WTRU, which may support dynamic waveform switch, receives system information blocks (SIBs) from multiple cells where at least one of them supports dynamic waveform switch, the WTRU may prioritize the initial access with the cell(s) that support dynamic waveform switch. If the WTRU supports dynamic waveform switch, the WTRU may send a physical uplink shared channel (RUSCH) in msg3 at a configured grant, which may be offset by a preconfigured number of slots with a waveform that is different from the preconfigured waveform type.Type: ApplicationFiled: April 5, 2023Publication date: July 17, 2025Applicant: InterDigital Patent Holdings, Inc.Inventors: Fumihiro Hasegawa, Virgil Comsa, Faris Alfarhan, Aata El Hamss, Paul Marinier, Moon-il Lee, Janet A.

Publication number: 20250142624Abstract: Devices, methods, and systems for coverage extension. A bundle of repeated transmissions of a preamble are transmitted responsive to a reference signal received power (RSRP) being less than a threshold and a random access (RA) procedure being initiated. A random access response (RAR) window is monitored for a random access radio network temporary identity (RA-RNTI) corresponding to the repeated transmissions of the preamble. In some implementations, each of the repeated transmissions of the preamble is transmitted based on a spatial filter that is different from others of the repeated transmissions of the preamble. In some implementations, each of the repeated transmissions of the preamble comprises a preamble index that is different from preamble indices of others of the repeated transmissions of the preamble. In some implementations, the spatial filter comprises a transmission (Tx) beam. In some implementations, the bundle of repeated transmissions of the preamble comprises retransmissions of a msg1.Type: ApplicationFiled: September 26, 2022Publication date: May 1, 2025Applicant: InterDigital Patent Holdings, Inc.Inventors: Faris Alfarhan, Paul Marinier, Fumihiro Hasegawa, Aata El Hamss, Moon IL Lee, Virgil Comsa

Publication number: 20250039728Abstract: Systems, methods, and instrumentalities are described herein for data transfer with energy harvesting (EH). EH may offer zero-energy consumption data communication. EH may impose intermittent connection drops due to battery shortage. If a certain condition is met (e.g., battery shortage), the RRC state or DRX/DTX configuration may be switched and data transfer operation may be suspended. EH may be performed to charge the battery/capacitor of the WTRU in the changed RRC state (e.g., new RRC state) or in a changed DRX/DTX operation (e.g., new DRX/DTX operation). If the state is transitioned or the DRX/DTX configuration is changed, protocol times (e.g., via all protocol timers) may be suspended and the user data maintained so that the transmitter and the receiver entities may resume data communication without any data loss or with very small loss of data.Type: ApplicationFiled: September 28, 2022Publication date: January 30, 2025Applicant: InterDigital Patent Holdings, Inc.Inventors: Brian Martin, Erdem Bala, Virgil Comsa, Keiichi Kubota, Janet A.

Publication number: 20250015947Abstract: Systems, methods, and instrumentalities are disclosed herein associated with transmission of demodulation reference signals (DMRS) in wireless systems. DMRS symbols may be placed in a slot for channel estimation operations. For example, channel estimation performance may be enhanced based on using an increased number of DMRS symbols. Channel estimation enhancements may be performed by transmitting DMRS symbols in an extended slot, for example, to avoid data degradation (e.g., which may result from replacing data transmission symbols with DMRS symbols). An extended slot may be a slot that includes symbols spanning across multiple slots (e.g., two slots, consecutive slots), for example, such as a slot n and a slot n+1.Type: ApplicationFiled: August 5, 2021Publication date: January 9, 2025Applicant: InterDigital Patent Holdings, Inc.Inventors: Fumihiro Hasegawa, Paul Marinier, Virgil Comsa, Moon-il Lee, Faris Alfarhan
