The invention provides a measurement reporting method of an unlicensed carrier, a terminal, a configuration method and a
base station. Wherein, the measurement reporting method includes: receiving a measurement control message sent by the
base station, wherein the measurement control message carries indication information, and the indication information is used to indicate the unlicensed carrier that needs to be measured; the measurement on the unlicensed carrier indicated by the indication information comes from different Multiple
pilot signals of the target
cell, and report the measurement results of the
pilot signals to the
air interface protocol layer layer three;
record the time stamps corresponding to the measurement results of the
pilot signals in the
air interface protocol layer layer three; the recorded time stamps The operation is performed on the
time difference between two adjacent time stamps, where the result of the operation is used to indicate the occupancy of the
base station on the unlicensed carrier and the condition that the terminal can receive the measured
pilot signal; report the result of the operation to the base
station. Through the present invention, the problem of call drop caused by the inability of the base
station to accurately make a reasonable judgment in the related art is solved.
