Abstract: The present invention relates to a base station, a small cell, and a method for scheduling a communications link resources. A first small cell reports load information and channel state information of a channel between the first small cell and a neighboring second small cell to a base station. The first small cell receives link pre-scheduling signaling from the base station. The link pre-scheduling signaling includes wireless resource occupation information that indicates an occupancy of a wireless resource of the first small cell by a backhaul link. The first small cell allocates a first wireless resource in available wireless resources to the backhaul link according to the channel state information and the wireless resource occupation information, and allocates a second wireless resource in the remaining available wireless resources to an access link used for data transmission between the first small cell and a user equipment device.

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.

Abstract: A method for preventing hand gesture misrecognition is provided. In the method for preventing hand gesture misrecognition, whether a user is exercising is recognized by obtaining motion data of the user in real time, to choose whether to disable a hand gesture recognition function. If the object user is exercising, the electronic device does not perform hand gesture recognition; or if the object user is not exercising, the electronic device performs hand gesture recognition. In addition, in the method, a trigger threshold for hand gesture recognition may further be adaptively adjusted based on a deflection angle between a human body plane of the user and a plane on which the electronic device is located.
