User terminal, radio base station and radio communication method

A radio base station comprising:

• a transmission section that transmits first pattern information, which indicates a time length and a periodicity of a first gap period, and second pattern information, which indicates a time length and a periodicity of a second gap period;
• and
• a receiving section that receives a measurement report, in which received signal intensity, which is measured in inter-frequency measurements in the first gap period that is configured based on the first pattern information, and/or reference signal received power and/or reference signal received quality, which are measured in inter-frequency measurements in the second gap period that is configured based on the second pattern information, are included.

A radio communication method between a radio base station and a user terminal, the radio communication method comprising, in the user terminal, the steps of:

• receiving first pattern information, which indicates a time length and a periodicity of a first gap period, and second pattern information, which indicates a time length and a periodicity of a second gap period;
• and
• measuring inter-frequency received signal intensity in the first gap period that is configured based on the first pattern information, and measuring inter-frequency reference signal received power and/or reference signal received quality in the second gap period that is configured based on the second pattern information.
