Patent number: 12262414Abstract: Beam determination refers to a set of procedures for an access node (AN) and a user equipment (UE) to select from among downlink communication beams and/or uplink communication beams for downlink and/or uplink communications, respectively. Often times, the downlink communication beams can include one or more downlink control channels, for example, a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH), to provide downlink reference signals, such as channel-state information reference signals (CSI-RSs), to the UE. The AN can execute various exemplary downlink beam scheduling procedures to control the transmission of the downlink reference signals, such as the CSI-RSs to provide an example, over the downlink communication beams. In some embodiments, the UE can utilize the CSI-RSs to perform beamforming failure detection (BFD) and beamforming failure recovery (BFR) in the wireless networks.Type: GrantFiled: October 16, 2020Date of Patent: March 25, 2025Assignee: Apple Inc.Inventors: Oghenekome Oteri, Yushu Zhang, Huaning Niu, Weidong Yang, Sigen Ye, Haitong Sun, Chunxuan Ye, Chunhai Yao, Hong He, Wei Zeng, Dawei Zhang

Patent number: 12262406Abstract: Uplink transmissions of a mobile device (UE) may be improved in a number of ways. Uplink Transmission Time Interval (TTI) bundling, including both Type-A and Type B PUSCH repetitions, may be implemented with variable TTI bundle sizing. The TTI bundle size may be determined by a base station and communicated to the UE explicitly, or may be determined by the UE implicitly, based on an indicated repetition number and frequency hopping number. The UE may also report frequency hopping (FH) assist information to the base station for use by the base station to more efficiently configure FH for the uplink transmissions. Finally, the UE may use (or maintain) the same transmission power, for each TTI transmit occasion of the same TTI bundle in order to improve (cross-slot) channel estimation accuracy. Power allocation may be prioritized to ensure that at the same time a total power for the uplink transmissions of the UE does not exceed a specified threshold.Type: GrantFiled: September 29, 2023Date of Patent: March 25, 2025Assignee: Apple Inc.Inventors: Hong He, Dawei Zhang, Wei Zeng, Haitong Sun, Chunhai Yao, Yushu Zhang, Chunxuan Ye, Seyed Ali Akbar Fakoorian, Weidong Yang

Patent number: 12262349Abstract: A base station may transmit beam indication information to one or more user equipment (UE) devices. For each of a plurality of time units (e.g., symbols) in a time interval (e.g., spanning one or more slots), the beam indication information indicates a corresponding beam that the base station will use to transmit or receive. A UE device may have knowledge of the beam in which it currently resides, e.g., by performing power measurements during a beam scan procedure. Thus, the beam indication information enables the UE to perform transmissions and/or receptions (e.g., configured transmissions and/or receptions) during the appropriate time unit(s). The beam indication information may be dynamically transmitted as part of downlink control information. This transmission may omni-directional, wide beam, or narrow beam. Various schemes of encoding the beam indication information are contemplated.Type: GrantFiled: October 15, 2020Date of Patent: March 25, 2025Assignee: Apple Inc.Inventors: Sigen Ye, Oghenekome Oteri, Haitong Sun, Yushu Zhang, Weidong Yang, Wei Zeng, Huaning Niu, Chunxuan Ye, Hong He, Chunhai Yao, Dawei Zhang

Patent number: 12262395Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a vehicle-to-everything (V2X) capable wireless device configured to perform sidelink cellular communications. The wireless device performs sidelink communications using a two-stage sidelink control information (SCI) protocol including Stage 1 SCI messaging carried on a physical sidelink control channel (PSCCH), and Stage 2 SCI messaging carried on a physical sidelink shared channel (PSSCH). The SCI messaging may be encoded using polar codes. Channel interleaving is utilized on the SCI to interleave the SCI between two or more layers of a MIMO transmission system. Scrambling for Stage 2 SCI messaging is performed based on the result of a cyclic redundancy check (CRC) performed on Stage 1 SCI messaging. Collisions between sidelink HARQ feedback to be transmitted to a base station and other transmissions are avoided based on a priority analysis of the sidelink HARQ feedback.Type: GrantFiled: August 24, 2023Date of Patent: March 25, 2025Assignee: Apple Inc.Inventors: Chunxuan Ye, Weidong Yang, Oghenekome Oteri, Chunhai Yao, Dawei Zhang, Haitong Sun, Hong He, Jie Cui, Wei Zeng, Yang Tang, Yuchul Kim, Yushu Zhang

Patent number: 12250660Abstract: Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within a prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.Type: GrantFiled: January 14, 2021Date of Patent: March 11, 2025Assignee: APPLE INC.Inventors: Chunxuan Ye, Chunhai Yao, Dawei Zhang, Haitong Sun, Hong He, Huaning Niu, Oghenekome Oteri, Seyed Ali Akbar Fakoorian, Sigen Ye, Wei Zeng, Weidong Yang, Yushu Zhang

Patent number: 12250668Abstract: Methods and apparatuses are disclosed for performing fast beam switching in a high-frequency wireless communication environment. Higher frequencies reduce transmission wavelength, which allows for an increased number of antennas and an increased number of beams. Therefore, beams become narrower and are more prone to failure. The UE must be capable of quickly identifying the beam failure and switching to a new beam. Therefore, the UE is capable of receiving multiple beams from the base station and configures both for testing and immediate use. In some cases, the UE can receive multiple beams for testing and assumes a default beam while feeding back to the base station a preferred beam. To support the larger number of available beams, MAC-CE and DCI are modified to identify this increased number of states. Alternatively, two MAC-CEs are sent, each containing a different group of states, and the DCI identifies both the group and the selected state.Type: GrantFiled: October 16, 2020Date of Patent: March 11, 2025Assignee: APPLE INC.Inventors: Oghenekome Oteri, Wei Zeng, Yushu Zhang, Weidong Yang, Dawei Zhang, Chunxuan Ye, Hong He, Haitong Sun

Patent number: 12250677Abstract: Systems and methods using control signaling for uplink frequency selective precoding at a user equipment (UE) are disclosed herein. A base station may indicate a transmission rank indicator (TRI), a wideband transmission precoder matrix indicator (TPMI), and one or more subband TPMI(s) to the UE. The base station may indicate, to the UE, whether to use the wideband TPMI or a subband TPMI to precode a physical uplink shared channel (PUSCH) transmission from the UE to the base station. The UE then precodes (and transmits) the PUSCH accordingly. Methods of UE application of the indicated subband TPMI(s) to subbands of the bandwidth in which a PUSCH may be transmitted are described. Methods accounting for a UE capability as to non-coherent, partial-coherent, and/or coherent precoding are described. Methods of assigning TPMI(s) to subbands in view of multiple transmission reception point (TRP) use by the UE for UE transmission are described.Type: GrantFiled: July 12, 2022Date of Patent: March 11, 2025Assignee: APPLE INC.Inventors: Yushu Zhang, Chunhai Yao, Chunxuan Ye, Dawei Zhang, Haitong Sun, Hong He, Seyed Ali Akbar Fakoorian, Wei Zeng, Weidong Yang

Patent number: 12250723Abstract: Methods and apparatuses are disclosed for signaling unused channel occupancy time (COT) to the gNB for COT sharing among other UEs. Upon determining that a portion of the maximum COT (MCOT) provided to the UE will be unused, the UE can generate COT sharing information for transmission back to the gNB. The COT sharing information identifies a starting point and a duration (e.g., a number of consecutive slots) of the unused portion of the MCOT. This information is then encoded into configured grant uplink control information (UG-UCI) and transmitted to the gNB as part of the uplink transmission. In aspects, the unused portion may begin part-way through a slot. In this instance, a starting symbol of the unused portion or an ending symbol of the used portion may also be encoded into the uplink transmission. In this manner, unused COT is not wasted, but rather repurposed by the gNB.Type: GrantFiled: May 14, 2020Date of Patent: March 11, 2025Assignee: APPLE INC.Inventors: Hong He, Chunhai Yao, Chunxuan Ye, Dawei Zhang, Haitong Sun, Jie Cui, Oghenekome Oteri, Wei Zeng, Wei Zhang, Weidong Yang, Yang Tang, Yuchul Kim, Yushu Zhang, Zhibin Wu
