Abstract: Embodiments of the present disclosure provide a method for receiving D2D discovery information and an apparatus. The method for receiving D2D discovery information includes: sending, by an upper layer of a radio resource control RRC layer of a D2D communication device, a first instruction to a physical layer of the D2D communication device, where the first instruction is used to instruct the physical layer to switch from a D2D sleep state to a D2D listening state; and receiving, by the physical layer of the D2D communication device, the first instruction and switching from the D2D sleep state to the D2D listening state according to the first instruction, to listen to D2D discovery information. This reduces power consumption of the D2D communication device and prolongs a standby time of the D2D communication device.

Abstract: A method and a system for implementing time division duplex configuration of a secondary serving cell are provided. A primary base station receives time division duplex TDD configuration information of a secondary serving cell and an identity of the secondary serving cell from a secondary base station, where the TDD configuration information of the secondary serving cell is allocated by the secondary base station to the secondary serving cell. The primary base station sends the TDD configuration information of the secondary serving cell and the identity of the secondary serving cell to a terminal, so that the terminal determines an uplink-downlink subframe allocation of the secondary serving cell according to the TDD configuration information.

Abstract: User equipment, a base station, a base station access method, and a radio link monitoring method are provided, where the user equipment includes: a first receiving module, configured to receive first indication information sent by a first base station,where the first indication information includes a time period required by the user equipment to initially request to access a second base station; a first sending module, configured to send the random access scrambling code to the second base station; and a first notification module, configured to: if the user equipment fails to access the second base station within the time period, notify the first base station that a secondary cell group failure occurs. In this application, efficiency of accessing the second base station by the user equipment is improved by limiting a time in which the user equipment requests to access the second base station.

Abstract: A cell discovery method, device, and system are disclosed, which relate to the radio communications field, so as to purposefully perform small-scale search and measurement, thereby improving the search efficiency and saving power. The method includes: after receiving first radio frequency information of a handover area and second radio frequency information reported by a user equipment served by a cell of a first base station, detecting, by the first base station, whether the second radio frequency information matches the first radio frequency information; if match, sending a measurement instruction message to the user equipment that reports the second radio frequency information, so as to instruct the user equipment to measure signal strength and/or signal quality of a cell at a frequency of a cell of a second base station or only of the cell of the second base station. Solutions disclosed are used for cell search and discovery.

Abstract: The present disclosure discloses a method for reporting a measurement report of a measurement event, including: determining that a measurement event is generated in a user equipment (UE) in an activated state of discontinuous reception (DRX) mode; judging whether a first time to trigger corresponding to the measurement event is valid when it is determined that there is a measurement event generated; using, when it is judged that the first time to trigger is valid, the first time to trigger to time the measurement event; using, when it is judged that the first time to trigger is invalid, a second time to trigger to time the measurement event, such that the UE is in next one or next several activated states of DRX mode after the generation of the measurement event. The present disclosure can improve a success rate of mobility handover between cells or wireless link quality.

Abstract: This application discloses a resource reconfiguration method, a base station, and a user equipment. The method includes: receiving, by a primary base station, a first message, where the first message is used to request to reconfigure, for a user equipment, a resource corresponding to a secondary base station; and initiating, by the primary base station, reconfiguration of the resource corresponding to the secondary base station for the user equipment. By means of this application, the resource corresponding to the secondary base station can be reconfigured for the user equipment in a case in which the secondary base station does not provide a reconfiguration function.

Abstract: A radio connection re-establishment where first preset numbers and/or durations are obtained. The multiple present numbers and/or durations correspond to one or more of, different cell coverage ranges of different types of cells, different transmit power strengths of the different types of cells, physical cell identifiers (PCIs) of the different types cells, types of the different types of cells, and/or first ranges of the different types of cells. A first range of a cell, among the different types of cells, is a range in which a signal strength of the cell in a coverage range of a macro cell, among the different types of cells, is greater than a signal strength of a macro cell among the different types of cells. The first present numbers and/or durations are sent to a user equipment (UE).
