Patent number: 11917464Abstract: Apparatuses, systems, and methods for RACH procedures to avoid excessive handover/secondary cell group failures. A base station may declare a handover and/or secondary cell group (SCG) failure and may determine that a failure threshold has been met. The base station may perform a remedial action in response to meeting the failure threshold. The failure threshold may be multi-dimensional, where a first dimension is associated with a number of handover/SCG failures and where a second dimension is associated with a time period in which the number of handover/SCG failures occurred. Further, a third dimension may be associated with a UE mobility state and a fourth dimension may be associated with whether the UE is using FR1 or FR2. The remedial action in response to meeting the failure threshold may include the base station suspending transmission of measurement object configurations for a specified period of time.Type: GrantFiled: May 26, 2021Date of Patent: February 27, 2024Assignee: Apple Inc.Inventors: Muhammad Saad, Syed A Rahim, Sharad Garg, Vijay Venkataraman, Jia Tang, Wenping Lou, Thanigaivelu Elangovan, Pengkai Zhao, Tarakkumar G Dhanani

Publication number: 20240040514Abstract: User equipment includes a first antenna, a second antenna, a first transceiver coupled to the first antenna, a second transceiver coupled to the second antenna, and processing circuitry communicatively coupled to the first transceiver and the second transceiver. The first transceiver receives or transmits a first signal via the first antenna, and the second transceiver receives or transmits a second signal via the second antenna. The processing circuitry receives an indication that a signal characteristic of the first signal is less than a first threshold, and decreases power to the first antenna, the first receiver, or both, based on the signal characteristic of the first signal being less than the first threshold.Type: ApplicationFiled: August 1, 2022Publication date: February 1, 2024Inventors: Xuan Guo, Xu Zhao, Mohamed L Haidara, Syed A. Rahim, Baohua Zheng, Wenping Lou

Publication number: 20230403650Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing cell search based on battery conditions of a user equipment (UE). For example, some aspects of this disclosure relate to a UE. The UE includes a transceiver configured to enable wireless communication with a base station and a processor communicatively coupled to the transceiver. The processor is configured to perform a cell search cycle in response to a determination that a connection with the base station has been lost. In response to a determination that UE is in a no-service mode or in a limited-service mode after the cell search cycle, the processor further configures a sleep timer value based at least on one of a charge level of a battery of the UE or a capacity level of the battery. The processor further performs a second cell search cycle after the configured sleep timer value.Type: ApplicationFiled: June 10, 2022Publication date: December 14, 2023Applicant: Apple Inc.Inventors: Ehsan Ahmed Quadri SYED, FNU Srinivas Kote Narasimhamurthy, Mohamed Lamine Haidara, Mohammad H.

Publication number: 20230099276Abstract: Systems and processes are for measuring link metrics for a plurality of reference signals associated with a plurality of beams from a base station. The systems and methods are for determining that a link metric value is less than or equal to a predetermined threshold. The systems and process include detecting beam failure, classifying beam recovery as high priority, opportunistic beam failure recovery and performing an optimal random access channel (RACH) process through intelligent selection of beams and modules.Type: ApplicationFiled: September 15, 2022Publication date: March 30, 2023Inventors: Muhammad Saad, Syed A. Rahim, Nitin A. Naik, Gopi Krishna Koneru, Vijay Venkataraman, Neeraj D. Vaghela

Publication number: 20230078257Abstract: Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.Type: ApplicationFiled: September 24, 2022Publication date: March 16, 2023Inventors: Vijay Venkataraman, Muthukumaran Dhanapal, Li Su, Sharad Garg, Syed A. Rahim, Sandeep K. Sunkesala, Jia Tang, Vijay Gadde, Tarakkumar G. Dhanani, Muhammad Saad

Patent number: 9485742Abstract: In order to facilitate communication in a wireless network, an accessibility issue in the wireless network may be detected. For example, if an electronic device is near the boundary between two adjacent cells in the cellular-telephone network, the signal power of signals from a current cell or connection may decrease. Concurrently, the maximum transmit power of the electronic device may be constrained by a thermal limit of the electronic device. When this occurs, the connection may be lost unless remedial action is taken. Therefore, in response to this condition, the electronic device may temporarily increase the maximum transmit power to allow the electronic device to communicate with the cellular-telephone network so that the connection may be transitioned to another cell or connection. In this way, the communication technique may restore the communication performance and avoid a dropped call, which will improve the user experience and customer satisfaction.Type: GrantFiled: January 10, 2013Date of Patent: November 1, 2016Assignee: Apple Inc.Inventors: Kwangho Byun, Rajesh Ambati, Syed A.
