Patent number: 11871474Abstract: Coordinated leaving for a UE having a first SIM and a second SIM may include decoding, at a baseband processor, an RRC reconfiguration message associated with the first SIM received from a first network. A communication corresponding to the second SIM received from a second network is decoded while the baseband processor is processing the received RRC reconfiguration message. The communication received from the second network is determined to comprise a higher priority than the RRC reconfiguration procedure. Based on determining, a UAI message corresponding to the first SIM is encoded by the baseband processor for transmission to the first network. The UAI message is configured to inform the first network of coordinated leaving and abortion of the RRC reconfiguration procedure. The first SIM is transitioned to an idle mode. An RRC request corresponding to the second SIM is encoded by the baseband processor for transmission to the second network.Type: GrantFiled: January 14, 2021Date of Patent: January 9, 2024Assignee: APPLE INC.Inventors: Srirang A.

Patent number: 11696121Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE), comprises one or more baseband processors to derive a dynamic scrambling key, and a memory to store the dynamic scrambling key and a temporary UE identifier (temporary UE ID) assigned to the UE. The one or more baseband processors monitor a paging request for a scrambled UE identifier (UE ID) to determine if the paging request is intended for the UE by unscrambling the scrambled UE ID with the dynamic scrambling key to produce the temporary UE ID. The paging request is intended for the UE if the temporary UE ID produced by unscrambling the scrambled UE ID matches the temporary UE ID stored in the memory. A new dynamic scrambling key may be derived each time the UE returns to a radio resource control idle (RRC_IDLE) state.Type: GrantFiled: May 3, 2017Date of Patent: July 4, 2023Assignee: Apple Inc.Inventors: Sudeep M.

Publication number: 20220312535Abstract: Systems, apparatus and methods enable layer 2 (L2) relaying optimizations for a remote user equipment (UE) to receive system information (SI) from a relay UE. The relay UE may establish a sidelink communication channel with the remote UE that is in a radio resource control (RRC) idle state, an RRC inactive state, or an out-of-coverage (OOC) state with respect to the base station. The relay UE decodes a relay SI request received through the sidelink communication channel from the first remote UE. The relay SI request indicates requested system information. The Relay UE obtains the requested system information or a subset of the requested system information from a memory device or from the base station and encodes a relay SI response to send to the first remote UE. The relay SI response includes the requested system information or the subset of the requested system information.Type: ApplicationFiled: April 13, 2021Publication date: September 29, 2022Inventors: Zhibin Wu, Fangli Xu, Birgit Breining, Dawei Zhang, Haijing Hu, Longda Xing, Sethuraman Gurumoorthy, Srirang A.

Patent number: 11057962Abstract: Techniques described herein may be used to enable User Equipment (UE) to efficiently and reliably report supported band combinations to a wireless network. An enhanced NodeB (eNB) may determine eNB-supported bands combinations for carrier aggregation scenarios, create a simplified representation of the eNB-supported bands combinations (e.g., using a highest order band combination, groups of band combinations, etc.), and communicate the eNB-supported bands combinations to the UE. The UE may determine UE-supported band combinations that are among the eNB-supported bands combinations, create a simplified representation of the UE-supported band combinations, and communicate the eNB-supported bands combinations to the eNB. The eNB may use the UE-supported band combinations to allocate appropriate carriers to the UE for carrier aggregation.Type: GrantFiled: November 3, 2017Date of Patent: July 6, 2021Assignee: Apple Inc.Inventors: Shadi Iskander, Naveen Palle, Candy Yiu, Birgit Breining, Youn Hyoung Heo, Hesham Elhelw

Patent number: 10966067Abstract: Downlink spectral capacity of an eMBMS cell to be maximized for the eMBMS users. In one embodiment, supplementary eMBMS cells may be used together with a primary cell, in which the supplementary eMBMS cells broadcast only eMBMS content and the primary cell is used for uplink and downlink signaling. The primary cell may perform signaling for the corresponding supplementary cells. In this manner, signaling relating to configuring of the eMBMS cells may be offloaded to the non-eMBMS primary cell and eMBMS specific services can be fully utilized from the eMBMS cells. In a second embodiment, an eMBMS cell may be a standalone eMBMS cell that is not associated with a primary cell. In this embodiment, self-contained eMBMS signaling is defined. Additionally, eMBMS data may be broadcast in specified MBSN subframes. In this manner, a device, such as an eMBMS-only device, can independently receive eMBMS services.Type: GrantFiled: May 11, 2017Date of Patent: March 30, 2021Assignee: Apple Inc.Inventors: Ajay Panchal, Hyung-Nam Choi, Birgit Breining
