TECHNICAL FIELD

The present invention relates to a user equipment and a base station apparatus in a wireless communication system.

BACKGROUND ART

For New Radio (also referred to as “5G”), a successor system to Long-Term Evolution (LTE), techniques that satisfy requirements such as a large capacity system, high data transmission speed, low delay, simultaneous connections of a number of terminals, low cost, and low power consumption have been discussed (e.g., Non-Patent Document 1).

As a requirement for user equipment measurements, NR specifies permissible delay time from the occurrence of an event to be measured to transmission of a measurement report (e.g., Non-Patent Document 2)

SUMMARY OF THE INVENTION

Problem to be Solved by the Invention

In a NR wireless communication system, since a user equipment sends a measurement report within the permissible delay time, measurements need to be performed with a uniform period regardless of communication conditions to obtain measurement results.

In view of the above, it is an object of the present invention to allow a user equipment to effectively perform measurements in a wireless communication system.

Means to Solve the Problem

According to the disclosed technique, there is provided a user equipment comprising a reception unit configured to receive from a base station apparatus a measurement configuration including an event that sets a condition for sending a measurement report, a control unit configured to perform a measurement based on the measurement configuration and a transmission unit configured to send to the base station apparatus a measurement report based on a result of the performed measurement when a condition for sending the measurement report is met, wherein the control unit determines, based on the result of the performed measurement, a period with which a measurement is performed.

Advantage of the Invention

According to the disclosed technique, the user equipment can effectively perform measurements in a wireless communication system.
