Publication number: 20230156502Abstract: An approach is described for a user equipment (UE) to receive a channel state information (CSI) reporting configuration message from a source device of a first cell and receive a channel state information reference signal (CSI-RS) from a second cell via the source device. The UE determines a first number of CSI-RS resources of a first time slot duration corresponding to the first cell, a second number of CSI-RS resources of a second time slot duration corresponding to the second cell, an overall time slot duration based on the first and the second time slot duration, an overall number of CSI-RS resources of the overall time slot duration based at least on the first and the second number of CSI-RS resource, generates a capability report at least based on the overall number of CSI-RS resource, and transmits the capability report to the source device.Type: ApplicationFiled: August 5, 2020Publication date: May 18, 2023Applicant: Apple Inc.Inventors: Haitong SUN, David NEUMANN, Dawei ZHANG, Ghaith N.

Publication number: 20230156753Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.Type: ApplicationFiled: December 19, 2022Publication date: May 18, 2023Inventors: Chunhai Yao, Chunxuan Ye, Dawei Zhang, Ghaith N.

Patent number: 11653311Abstract: A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.Type: GrantFiled: February 12, 2021Date of Patent: May 16, 2023Assignee: Apple Inc.Inventors: Haitong Sun, Yushu Zhang, Wei Zeng, Dawei Zhang, Ismael Gutierrez Gonzalez, Ghaith N.

Publication number: 20230067545Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform CSI-reporting. In an example, a BWP includes “M” subbands and is configured to the UE. The UE can process “Kc” CSI-RS samples to generate “M” subband CSI reports, where “Kc>M.” The UE determines what number of CSI-RS samples to use per subband based on the channel information of the BWP, where this number can vary between the subbands.Type: ApplicationFiled: July 19, 2022Publication date: March 2, 2023Applicant: Apple Inc.Inventors: Ghaith N.

Publication number: 20230042538Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing capability signaling design for 3rd Generation Partnership Project (3GPP) release 15 (Rel-15) and/or release 16 (Rel-16) multi-input multi-output (MIMO) enhancement. For example, systems and methods are provided implementing designs for New Radio (NR) MIMO channel state information (CSI) for a small bandwidth part (BWP) and/or a small number of subbands. For example, some aspects relate to a user equipment (UE) including a transceiver configured to communicate with a base station and a processor communicatively coupled to the transceiver. The processor receives, from the base station, a CSI reporting configuration message. The processor determines, using the CSI reporting configuration message, that a number of physical resource blocks (PRBs) of a BWP associated with the CSI reporting configuration message is less than a threshold number. The processor also generates and transmits a CSI report for the BWP.Type: ApplicationFiled: April 8, 2020Publication date: February 9, 2023Applicant: Apple Inc.Inventors: Haitong SUN, David NEUMANN, Dawei ZHANG, Ghaith N.

Patent number: 11152994Abstract: The systems, methods, and apparatuses can receive one or more communication signals traversing through a communication channel. The systems, methods, and apparatuses can estimate one or more known parameters, characteristics, and/or attributes of the communication channel, for example, scattering, fading, and/or power decay over distance, through a process referred to as channel estimation. The systems, methods, and apparatuses can develop various channel coefficients, for example, amplitudes and/or phases, describing the channel response of the communication channel at discrete intervals of time, also referred to as taps. The systems, methods, and apparatuses can assign taps to various priorities and, thereafter, utilize these priorities to selectively include their corresponding channel coefficients in a CSI report or exclude their corresponding channel coefficients from the CSI report.Type: GrantFiled: May 27, 2020Date of Patent: October 19, 2021Assignee: Apple Inc.Inventors: Weidong Yang, Chunhai Yao, Chunxuan Ye, Dawei Zhang, Haitong Sun, Hong He, Ismael Gutierrez Gonzalez, Wei Zeng, Wei Zhang, Yuchul Kim, Yushu Zhang
