Abstract: The present invention provides a method, a device, and a system for inter-frequency cell measurement. The method includes: performing, by a terminal, when receiving a measurement command of a network side device, inter-frequency cell measurement, in different cases, based on the time specified in different measurement time parameters or based on measurement time parameters corresponding to the information about an inter-frequency band. As different measurement time parameters specify different time actually used for measurement, not only an inter-frequency cell that meets a measurement event can be measured, but also the time for measurement by the terminal can be reduced, thereby reducing the power consumption of the terminal and enhancing the performance of the terminal.

Abstract: The present application discloses an information notification method, a user terminal, a first base station, and a second base station. UE receives a notification message that is sent by a first base station by using a managed first cell, where the notification message is used to instruct the UE to acquire system information of a second cell managed by a second base station; and the UE acquires, according to the received notification message, the system information of the second cell managed by the second base station. A D2D resource configuration of the second cell changes but is not read by the UE in time, resulting in a problem that the UE uses an expired D2D resource configuration.

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.
