1. A method, comprising,
receiving, by a wireless device from a network, a first measurement configuration including information related to a first measurement window;
performing, by the wireless device, first measurements for a first cell based on the first measurement window;
detecting, by the wireless device, a failure of the first measurements for the first cell, based on that a number of beams or a number of reference signals measured within the first measurement window is less than a first minimum number of beams or a first minimum number of reference signals;
determining, by the wireless device, i) a first offset between a last measured beam or a last measured reference signal within the first measurement window and an end of the first measurement window and ii) a second offset between a start of the first measurement window and a first measured beam or a first measured reference signal within the first measurement window, upon detecting the failure of the first measurements; and
transmitting, by the wireless device to the network, a failure report including i) information informing that the first measurements for the first cell are failed, ii) information related to the first offset and the second offset, and iii) information related to the number of beams and the number of reference signals measured within the first measurement window.
