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.

Abstract: A synchronization processing method, including sending, in a first time unit, by a network device, a first synchronization signal having one or more first beams to a terminal device, and sending, in a second time unit, a second synchronization signal having one or more second beams to the terminal device. The first synchronization signal and the second synchronization signal cause the terminal device to determine, according to the first synchronization signal and the second synchronization signal, an optimal transmit beam of the network device for the terminal device from the one or more first beam and the one or more second beams, and further to determine a time sequence in which the optimal transmit beam is located. A time offset corresponding to each first beam and second beams is different, and is a difference between a time sequence of the beams and a time sequence of the second beams.

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. This is to ensure coexistence and performance of systems when an LBT requirement of a high unlicensed frequency band is met.

Abstract: The present application relates to the field of communications technologies, and provides an inter-small cell handover method, a device, and a system. When UE is in a coverage hole of a serving small cell, the UE needs to perform synchronous measurement only on each available beam pair in a set of available small cells determined by the UE, thereby reducing a delay of re-accessing a high frequency network by the UE, and improving QoS of receiving a high frequency service by the UE. the present application includes: performing, by UE, synchronous measurement, to determine a set of small cells available for the UE; sending the set of available small cells to a macro base station; when the UE is in a coverage hole of a current serving small cell, receiving, by the UE, a first synchronization indication sent by the macro base station.

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 relates to a data transmission method and a base station, the method includes: determining, by a base station according to channel state information CSI, a transmission path for forwarding first data to a first terminal, where if the base station determines that the first data needs to be forwarded by at least one small cell to the first terminal, the transmission path includes a path from the base station to a small cell and a path from the small cell to the first terminal; and sending, by the base station according to the transmission path, a first data frame to the first terminal via the at least one small cell. In the present invention, a macro base station performs centralized scheduling, and performs unified encapsulation according to a scheduled transmission path, thereby effectively simplifying processing by a forwarding node and reducing a delay.
