Patent number: 12214099Abstract: Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.Type: GrantFiled: March 6, 2024Date of Patent: February 4, 2025Assignee: Apple Inc.Inventors: Srirang A Lovlekar, Sethuraman Gurumoorthy, Murtaza A.

Patent number: 12218767Abstract: Techniques, described herein, include solutions for managing hybrid automatic repeat request (HARQ) processes and communications for non-terrestrial networks (NTNs) (e.g., a wireless communication network that includes a satellite network component). A user equipment (UE) may connect to an NTN and determine hybrid automatic repeat request (HARQ) capabilities regarding NTNs. The UE may also communicate a HARQ disablement message to the NTN and communicate with NTN without HARQ procedures. The HARQ disablement message may provide the HARQ disablement capabilities of the UE and/or be a request for the network to disable HARQ. The HARQ disablement message may include a radio resource control (RRC) reconfiguration message and may address HARQ disablement per logical channel identifier (LCID) or dedicated radio bearer (DRB).Type: GrantFiled: August 5, 2021Date of Patent: February 4, 2025Assignee: Apple Inc.Inventors: Haijing Hu, Sarma V Vangala, Alexander Sirotkin, Chunxuan Ye, Dawei Zhang, Fangli Xu, Naveen Kumar R Palle Venkata, Pavan Nuggehalli, Ralf Rossbach, Sethuraman Gurumoorthy, Yuqin Chen, Zhibin Wu

Publication number: 20240397520Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.Type: ApplicationFiled: August 5, 2024Publication date: November 28, 2024Applicant: Apple Inc.Inventors: Fangli XU, Sethuraman GURUMOORTHY, Huaning NIU, Yushu ZHANG, Chunhai YAO, Wei ZENG, Haitong SUN, Weidong YANG, Dawei ZHANG, Sigen YE
