  • Patent number: 10827405
    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.

  • Publication number: 20170273094
    Abstract: Embodiments of the present application provide a resource scheduling method, user equipment, and a base station. The method includes: determining a resource scheduling priority of UE according to location assistance information of the UE, where the location assistance information of the UE is used to indicate a location relationship between the UE and an edge area of a high-frequency coverage area; and allocating a time-frequency resource to the UE according to the resource scheduling priority of the UE. In the embodiments of the present application, a resource scheduling priority of UE is determined according to location assistance information that is determined according to a location relationship between the UE and an edge area of a high-frequency coverage area, so that the edge user of the high-frequency communication blind area has relatively desirable user experience.
