Abstract

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.

Description

technical field [0001] The present invention relates to the field of communications, in particular, to a measurement reporting method of an unlicensed carrier, a terminal, a configuration method and a base station. Background technique [0002] In mobile communication systems, cell reselection and handover are important functions. In order to realize cell reselection smoothly, UE (User Equipment) needs to measure the signal quality of different cells in order to select a suitable cell to camp on. After the UE establishes a connection with the network in a certain cell, the UE still needs to measure the signal quality of its neighboring cells in order to select a suitable cell for handover and meet mobility requirements. [0003] In the Long Term Evolution (LTE, Long Term Evolution) system, in the connected state, the specific process of measurement is: the network side sends a measurement control message to the UE, wherein the measurement control message includes a measurem...
