Publication number: 20240146399Abstract: A communications system may include user equipment (UE) device, satellites, and a gateway. The UE and gateway may perform implicit handover in which the UE and gateway independently identify the same serving satellite using ephemeris data, without additional signaling overhead. The UE may also characterize its channel conditions. When insufficient, the UE may transmit an explicit handover message to the gateway via a different satellite visible to the UE. The explicit handover message may include a satellite identifier and a lock bit. The gateway may use the satellite identifier to convey wireless data with the UE via the different satellite during the next cycle. The gateway may use the lock bit to know how to perform handover away from the different cycle during subsequent cycles. In this way, the UE may direct handover, given that the gateway has no knowledge of the channel condition at the UE.Type: ApplicationFiled: September 19, 2022Publication date: May 2, 2024Inventors: Sudeep Bhattarai, Lohit Sarna, Nishant Pattanaik, Seshu Tummala, Saurabh Deo, Sebastian B.

Patent number: 11956057Abstract: User equipment includes one or more antennas, a receiver coupled to the one or more antennas, and processing circuitry coupled to the receiver and configured to cause the user equipment to receive downlink signals at each communication cycle using a predetermined beam in a beam time slot. Based on processed downlink signals and other relevant information the user equipment may determine a desired beam for the next communication cycle. If the desired beam is the same as the predetermined beam, the user equipment may continue using the predetermined beam at the next communication cycle. If the desired beam is different from the predetermined beam, the user equipment may switch to the desired beam at the next communication cycle. In this way, the user equipment may continue tracking a desired beam to maintain reliable data communications with a communication node.Type: GrantFiled: August 18, 2022Date of Patent: April 9, 2024Assignee: Apple Inc.Inventors: Sudhir K Baghel, Sudeep Bhattarai, Amol P Bhatkar, Seshu Tummala, Venkateswara Rao Manepalli, Mehran T Baghaei, Lohit Sarna, Nishant Pattanaik, Jay P Shah

Publication number: 20240097740Abstract: Frequency spectrum of wireless transmission signals are allocated based on availability and regulatory requirements. To ensure transmission signals are within designated channel boundary, user equipment utilizes processing circuitry coupled to a transceiver to pre-compensate for estimated frequency shift at the time of transmissions. Certain guard bands are provided such that the actual transmission signals with the frequency pre-compensation are within the designated channel boundary. Additionally, or alternatively, the user equipment utilizes the processing circuitry to pre-compensate for estimated time shift based on a crystal drift using temperature measurement.Type: ApplicationFiled: September 19, 2022Publication date: March 21, 2024Inventors: Sudhir K. Baghel, Seshu Tummala, Amol P. Bhatkar, Mehran T. Baghaei, Venkateswara Rao Manepalli, Nishant Pattanaik, Sudeep Bhattarai, Lohit Sarna, Jay P. Shah, Sebastian B. Seeber

Patent number: 8356296Abstract: A method and system for resetting a network device. Specifically, in one embodiment, a method is disclosed for upgrading and/or reloading software for a network device with minimal disruption. The method begins by separating operations associated with layer two of an International Standardization Organization Open Systems Interconnect (ISO/OSI) reference model from other layers in the ISO/OSI reference model in a network device. Then, the software operations in layer two of the network device are reset. The software operations are reset while maintaining continuity for a communication session between the network device and other network devices coupled together through a network. Thereafter, for minimal disruption, execution of the software operations is recovered at layer two before continuity of the communication session s terminated.Type: GrantFiled: August 6, 2010Date of Patent: January 15, 2013Assignee: Cisco Technology, Inc.Inventors: John Thomas Welder, Ratheesh Krishna Vadhyar, Sudhir Rao, Thomas W.

Patent number: 8135424Abstract: A cooperative sensing technique (300) operates by selecting a group of subscribers (302) from a secondary system, measuring a cooperative sensing metric (306) and then using the metric to identify an achievable spatial diversity gain for the group of selected subscribers (308). Once an achievable spatial diversity gain is determined for the group (308/412), it is compared to a required spatial diversity gain (310), and if the condition is met at (310), the validated group can begin spectrum sensing (314) to identify a vacant/suitable channel for operation. If the achievable spatial diversity gain is insufficient, then a new group of users is selected (312) within the secondary system and the process repeats itself.Type: GrantFiled: December 3, 2008Date of Patent: March 13, 2012Assignee: Motorola Solutions, Inc.Inventors: Yadunandana N. Rao, Apoorv Chaudhri, Sudhir Rao
