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.
