Abstract: The present invention provides a synchronization method of user equipment and user equipment, where the method includes: when the user equipment accesses a millimeter-wave band network, performing first synchronization in a cellular band by using a cellular band network that covers the millimeter-wave band network; and performing second synchronization in a millimeter-wave band by using the millimeter-wave band network. In the present invention, after the first synchronization in the cellular band is performed, the second synchronization in the millimeter-wave band is performed by using the millimeter-wave band network, which avoids a case in which the user equipment acquires a PSS in a PSS synchronization window that slides in the millimeter-wave band for a long time, thereby reducing overheads, narrowing a range of the synchronization window, and accelerating detection of a PSS in the millimeter-wave band, so that the user equipment quickly and accurately performs synchronization in the millimeter-wave band.

Abstract: The present invention discloses a data sending method and a communications device. The method includes: sensing, by a communications device, a carrier located in a first unlicensed frequency band, where the first unlicensed frequency band includes at least one carrier; and sending, by the communications device, data on a carrier whose channel state is sensed to be idle. The communications device senses a first carrier in the first unlicensed frequency band, and sends the data on the first carrier that is successfully sensed to be idle. Another communications device may also sense in the first unlicensed frequency band, and send data in the first unlicensed frequency band when sensing successfully. Therefore, users of different services may fairly contend and coexist in an unlicensed frequency band.

Abstract: A channel access method is provided. Under the method, a network element performs random backoff listen before talk (LBT) for channel preemption, and after the preemption succeeds, performs signal transmission in the first transmission time interval TTI within a maximum channel occupancy time MCOT. The network element also performs nonrandom backoff LBT for channel preemption before another at least one TTI within the maximum channel occupancy time MCOT.

Abstract: Embodiments of the present disclosure provide a signal synchronization method and apparatus for high frequency communication, and pertain to the field of wireless communications technologies. The method includes: performing, on a first beam pair, high frequency data communication with user equipment; if it is determined that the user equipment enters a dead zone state, sending a synchronization indication signal to the user equipment, where the synchronization indication signal includes at least quick synchronization indication information and user equipment information, and the user equipment information includes user ID information, beam ID information of a beam pair, and cell ID information; sending, on a specified high frequency resource, a synchronization signal to the user equipment. In the present disclosure, high frequency data communication is implemented by quickly performing re-synchronization in a dead zone state. Therefore, communication service quality is relatively high.
