  • Patent number: 10439741
    Abstract: A method, apparatus and user terminal for measuring with a discovery signal are disclosed in the present document. The method includes: when measuring reference signal receiving quality (RSRQ) based on a discovery signal, performing a received signal strength indication (RSSI) measurement in a sub-frame where a discovery signal is located and/or a sub-frame without the discovery signal; and acquiring the RSRQ according to the measured RSSI. With the present document, the RSSI measurement is performed based on the sub-frame where the discovery signal is located and/or the sub-frame without the discovery signal, which can reduce the measurement deviation caused by the situation that there is no data in a data channel after a cell is closed, and increase the RSRQ measurement accuracy.
