  • Patent number: 9480035
    Abstract: The present invention is applicable to the field of communications technologies, and provides an in-synchronization and out-of-synchronization handling method and apparatus. The method includes: reporting, by a physical layer, an invalid frame indication to a high layer, where the invalid frame indication is used to indicate an invalid frame, and the invalid frame is a frame not used for detecting out-of-synchronization, so as to count the number of frames that are assured to be out of synchronization within timing; and when the number of frames that are assured to be out of synchronization within the timing reaches a predefined value, determining that a radio link is out of synchronization. By using the present invention, the modified timing of the timer and the number of in-synchronization indications correspond to each other.

  • Patent number: 9419521
    Abstract: A control method and a control apparatus are provided. The control method and apparatus are applied to a BUCK-BOOST topology. The method specifically is, processing an output signal of a topology to obtain a pulse width modulation signal, performing an OR operation between the pulse width modulation signal and a first modulation signal to obtain a first control signal so as to control a state of a first transistor on the topology, and performing an AND operation between the pulse width modulation signal and a second modulation signal to obtain a second control signal so as to control a state of a second transistor on the topology. Therefore, the method achieves three topology states and a smooth switchover among the three topology states. In addition, the control circuit is relatively simple, expanding the control scope and improving the control precision.
