Abstract: A method, a device and a system for signal transmission are disclosed in embodiments of the present invention. The method comprises: selecting a multiplexing mode of signals to be transmitted by a cell according to interference strength received by the cell and/or interference strength received by a neighboring cell; notifying a receiver of the multiplexing mode of the signals to be transmitted by the cell; and transmitting the signals to be transmitted by the cell according to the multiplexing mode of the signals to be transmitted by the cell. Through the signal transmission method, device and system provided herein, the multiplexing mode is selected adaptively according to the interference strength. Therefore, the inter-cell interference is reduced, the reliability of channel detection is improved, the system complexity is reduced, and the cost is saved.

Abstract: In the present application, when the problem of co-channel interference between base stations is eliminated, normal neighboring cell measurement can still be performed on a second base station by delaying receive/transmit transition time of the user equipment. The method includes: receiving, by the user equipment, first indication information sent by a first base station; determining, by the user equipment according to the first indication information, receive/transmit transition time needing to be delayed; determining, by the user equipment according to the receive/transmit transition time needing to be delayed, a downlink time of performing neighboring cell measurement for a second base station, and performing, by the user equipment, neighboring cell measurement for the second base station at the downlink time. The present application is applicable to the field of wireless communications systems.
