USER TERMINAL, RADIO BASE STATION AND INTER-FREQUENCY MEASUREMENT METHOD

摘要

The present invention is designed to reduce the load of inter-frequency measurements in user terminals in a radio communication system in which a plurality of CCs are used in each small cell within a macro cell. The inter-frequency measurement method of the present invention includes the steps of, from a radio base station forming a macro cell to a user terminal, transmitting the transmission timing information of a detection signal in a small cell, and the a timing shift value for detection signals of the plurality of CCs that transmitted with shifted timings in the small cell, and, in the user terminal, measuring the plurality of CCs in a measurement gap based on the transmission timing information and the timing shift value.

1. A user terminal in a radio communication system in which a plurality of component carriers (CCs) are used in a small cell within a macro cell, the user terminal comprising:
a receiving section that receives, from a radio base station forming the macro cell, transmission timing information of a detection signal in the small cell, and a timing shift value for detection signals of the plurality of CCs that are transmitted with shifted timings in the small cell; and a measurement section that measures the plurality of CCs in a measurement gap based on the transmission timing information and the timing shift value.
