The sequence synchronization apparatus includes: a signal receiving unit configured to receive a clock synchronized signal including a training symbol, the training symbol being in-phase modulated or being modulated with a fixed phase difference based on all or part of subcarriers; and a symbol detecting unit configured to detect the training symbol, so as to achieve sequence synchronization of the signal. With the embodiments of the present disclosure, not only sequence synchronization may be achieved by using minimum complexity as possible, but also the sequence synchronization apparatus is made simple, fast and accurate.Type: GrantFiled: October 9, 2014Date of Patent: September 8, 2015Assignee: FUJITSU LIMITEDInventors: Hao Chen, Lei Li, Weizhen Yan, Bo Liu

Patent number: 9118776Abstract: Methods, program products, and systems for baseband location monitoring and related functions are disclosed. A mobile device can monitor its own current location using its baseband subsystem and decide whether to selectively activate its application subsystem based on whether particular conditions are satisfied by the current location. The mobile device can also correlate location and cellular signal information using its baseband subsystem and provide the correlated location and cellular signal information to a server. The server can receive the correlated location and cellular signal information from the baseband subsystems of a large number of widely distributed mobile devices and generate respective profiles of cellular network base stations that transmitted the cellular signals to the mobile devices.Type: GrantFiled: June 3, 2011Date of Patent: August 25, 2015Assignee: Apple Inc.Inventors: Ronald K. Huang, Morgan Grainger, Robert Mayor

Patent number: 9119153Abstract: Methods and apparatus for power optimization in e.g., a wireless mobile device. In one embodiment, the optimization is effected via intelligent idle mode current drain management. In an exemplary LTE cellular network context, the user equipment (UE) only powers on its transceiver for a subset of Discontinuous Reception (DRX) cycles based on e.g., the quality of the radio environment, power considerations, location, etc. For example, if a UE has not moved, and its radio reception quality is good, the UE is likely to successfully receive a paging notification (i.e., without multiple attempts). Consequently, the UE configures itself to receive only a single paging indication.Type: GrantFiled: June 29, 2012Date of Patent: August 25, 2015Assignee: Apple Inc.Inventors: Giri Prassad Deivasigamani, Gaurav Nukala, Srinivasan Vasudevan

Patent number: 9119161Abstract: A method for controlling power in a wireless telephone set is provided. The method includes controlling a power supply to a receiving section and a transmitting section by using a transmitting section turn-on signal to turn on the transmitting section, when the transmitting section turn-on signal is received in a slot mode for alternating between a receiving condition and a sleeping condition at predetermined intervals, and when the transmitting section turn-on signal is not received, controlling the power supply to the receiving section according to the receiving condition of slot mode control signals during the slot mode when no interrupting signal has been detected.Type: GrantFiled: September 23, 2011Date of Patent: August 25, 2015Assignee: Samsung Electronics Co., LtdInventor: Jae-Sun Park
