    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 disclosure provides a method and a device for eliminating inter-system neighbor cell interference. The method includes the following steps: receiving, by a first wireless access device, a first interference indication, where the first interference indication is sent by a first terminal when the first terminal detects that neighbor cell interference caused by a second terminal to the first terminal is greater than or equal to a preset threshold, the first interference indication is used for indicating that the first terminal suffers the neighbor cell interference; sending, by the first wireless access device, a decreasing interference indication to a second wireless access device corresponding to the second terminal when determining that the first terminal suffers the neighbor cell interference from the second terminal, so that the second wireless access device executes a decreasing interference strategy to eliminate neighbor cell interference between the first terminal and the second terminal.

    Abstract: A method and system for LBT or CCA threshold setting for directional reception and transmission are provided. In an embodiment, a method in a wireless device for determining if a channel is clear in an unlicensed band channel in a wireless network includes detecting, with the wireless device, an energy along a first beamforming direction. The method also includes determining, with the wireless device, an energy detection threshold. The method also includes determining, with the wireless device, whether the unlicensed band channel is clear in at least the first receiving direction according to the energy and the energy detection threshold.
