detecting, by a physical layer of the wireless device, that a reference signal (RS) on an unlicensed frequency is not transmitted in a current period;
considering, by the physical layer, that a radio link status of the current period is identical to a radio link status of a previous period; and
informing, by the physical layer to a radio resource control (RRC) layer of the wireless device, the radio link status of the current period in the current period.
