Abstract: Method and device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded, to obtain one or more CSI-RS configuration codes. The CSI-RS configuration codes are sent to a terminal device. The terminal device determines, based on CSI-RS configuration codes, CSI-RS configuration information such as a quantity of antenna ports for transmitting a CSI-RS, a CSI-RS pattern, a CSI-RS period and an offset corresponding to the CSI-RS period.

Abstract: Embodiments of the present invention disclose a method for detecting a signal on an unlicensed spectrum channel, user equipment, and a base station. The method includes: receiving, by user equipment, instruction information sent by a base station; and starting, by the user equipment according to the instruction information, to detect a signal on an unlicensed spectrum channel. According to the present invention, only when receiving the instruction information sent by the base station, the user equipment detects the signal on the unlicensed spectrum channel according to the instruction information. This reduces power consumption of the user equipment.

Abstract: A method and a device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded, to obtain a CSI-RS configuration information code. A mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information is stored. A CSI-RS configuration information code corresponding to CSI-RS configuration information to be notified is searched in the stored mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information. The searched CSI-RS configuration information code is sent to a user equipment (UE), so that the UE determines CSI-RS configuration information according to the received CSI-RS configuration information code and the mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information.

Abstract: A method and device for sending a synchronization signal and a method and device for synchronization between base stations, include: determining, by a synchronization source base station according to a synchronization level of the synchronization source base station, a resource for sending an NLRS for clock synchronization between base stations, and according to the determined resource. In this way, one NLRS for clock synchronization between base stations is configured on each synchronization source base station, and the NLRS is sent on a resource determined according to a synchronization level, so that a synchronization base station that acquires the NLRS can determine the synchronization level of the synchronization source base station according to a resource for sending the NLRS.
