Method for measuring wireless link quality and user equipment

A user equipment, comprising:

• a first obtaining circuit, configured to obtain a probability that a base station successfully transmits a Discovery Reference Signal (DRS);
• a status detection circuit, configured to detect a Cell Specific Reference Signal (CRS) in each subframe in a predetermined assessment period, so as to obtain a subframe status of the each subframe, wherein the subframe status comprises a status that the CRS is detected and a status that the DRS is not detected in a wireless link measurement window;
• a determination circuit, configured to determine a status generation reason of a subframe having the status that the DRS is not detected in the wireless link measurement window, according to the probability that the base station successfully transmits the DRS;
• and
• a link state determination circuit, configured to perform predetermined detection to a quality of a wireless link in a predetermined assessment period according to the status generation reason and the subframe status of the subframe, so as to determine a state of the wireless link.
