Patent number: 12167405Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.Type: GrantFiled: July 12, 2023Date of Patent: December 10, 2024Assignee: InterDigital Patent Holdings, Inc.Inventors: Shahrokh Nayeb Nazar, Kyle Jung-Lin Pan, Robert L.

Patent number: 12155450Abstract: A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beamin the beam group.Type: GrantFiled: May 15, 2023Date of Patent: November 26, 2024Assignee: InterDigital Patent Holdings, Inc.Inventors: Kyle Jung-Lin Pan, Fengjun Xi, Afshin Haghighat, Oghenekome Oteri, Chunxuan Ye, Frank La Sita, Robert Olesen, Moon-il Lee

Publication number: 20240323874Abstract: An apparatus and method for synchronization between a WTRU and a gNB are disclosed. The WTRU may receive a multiple beam synchronization signal from the gNB during synchronization. For each beam received by the WTRU, of the multiple beam synchronization signal, the WTRU may compare a received energy of the beam against a first threshold. A multiple beam synchronization signal may include a first and second synchronization signal (SS). If one or more beams of the multiple beam synchronization signal meets or exceeds the first threshold, the WTRU may report an indication of pre-synchronization to the gNB. This pre-synchronization may indicate to the gNB that a WTRU exists in an area of a particular beam of the WTRU. In this way, a gNB may target the WTRU using transmissions directed towards the WTRU.Type: ApplicationFiled: June 3, 2024Publication date: September 26, 2024Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Kyle Jung-Lin Pan, Chunxuan Ye, Robert L.

Patent number: 12068909Abstract: Systems, methods and instrumentalities are disclosed for WTRU-initiated beam recovery including beam switching and/or beam sweeping. A WTRU may be configured to detect a beam failure condition, identify a candidate beam for resolving the beam failure condition, and send a beam failure recovery request to a network entity.

Publication number: 20240276510Abstract: Transmit and/or receive beamforming may be applied to the control channel transmission/reception, e.g., in mmW access link system design. Techniques to identify candidate control channel beams and/or their location in the subframe structure may provide for efficient WTRU operation. A framework for beam formed control channel design may support varying capabilities of mBs and/or WTRUs, and/or may support time and/or spatial domain multiplexing of control channel beams. For a multi-beam system, modifications to reference signal design may discover, identify, measure, and/or decode a control channel beam. Techniques may mitigate inter-beam interference. WTRU monitoring may consider beam search space, perhaps in addition to time and/or frequency search space. Enhancements to downlink control channel may support scheduling narrow data beams. Scheduling techniques may achieve high resource utilization, e.g., perhaps when large bandwidths are available and/or WTRUs may be spatially distributed.Type: ApplicationFiled: April 23, 2024Publication date: August 15, 2024Inventors: Yugeswar Deeno, Tao Deng, Kyle Jung-Lin Pan, Moon-il Lee, Ravikumar V.
