User terminal, processor, and mobile communication system
A user terminal according an embodiment, comprises: a controller configured to execute measurement based on a radio signal in a secondary cell in an unlicensed band; and a transmitter configured to transmit, to a base station, a report of measurement results based on the radio signal. The controller is configured to determine whether or not identification information to which a predetermined scramble is applied is detected from a predetermined radio signal in the secondary cell. The transmitter is configured to transmit, to the base station, the report of measurement results not including a predetermined measurement result based on the predetermined radio signal, in response to no detection of the identification information from the predetermined radio signal.
1. A user terminal, comprising:
a controller; and
a transmitter, wherein
the controller is configured to
receive a predetermined radio signal in a secondary cell in an unlicensed band, the secondary cell being managed by a serving base station of the user terminal; and
determine whether or not control information is detected from the predetermined radio signal, the control information being information to which a predetermined scramble is applied, and the control information being related to radio communication between the user terminal and the serving base station, and wherein
the transmitter is configured to
transmit a report of measurement results including a predetermined measurement result based on the predetermined radio signal, in response to determining that the control information is detected from the predetermined radio signal, and
transmit the report of measurement results not including the predetermined measurement result, in response to determining that the control information is not detected from the predetermined radio signal.
2. The user terminal according to claim 1 , wherein the control information is information imparted with a CRC (Cyclic Redundancy Check) code.
3. A processor, comprising:
a memory communicatively coupled to the processor and including instructions, such that when executed by the processor, the processor performs the processes of:
receiving a predetermined radio signal in a secondary cell in an unlicensed band, the secondary cell being managed by a serving base station of the user terminal;
determining whether or not control information is detected from the predetermined radio signal, the control information being information to which a predetermined scramble is applied, and the control information being related to radio communication between the user terminal and the serving base station;
transmitting a report of measurement results including a predetermined measurement result based on the predetermined radio signal, in response to determining that the control information is detected from the predetermined radio signal; and
transmitting the report of measurement results not including the predetermined measurement result, in response to determining that the control information is not detected from the predetermined radio signal.
4. A mobile communication system, comprising:
a user terminal; and
a serving base station of the user terminal, wherein
the serving base station manages a secondary cell in an unlicensed band,
the user terminal receives a predetermined radio signal in the secondary cell in the unlicensed band,
the user terminal determines whether or not control information is detected from the predetermined radio signal, the control information being information to which a predetermined scramble is applied, and the control information being related to radio communication between the user terminal and the serving base station,
the user terminal transmits a report of measurement results including a predetermined measurement result based on the predetermined radio signal, in response to determining that the control information is detected from the predetermined radio signal, and
the user terminal transmits the report of measurement results not including the predetermined measurement result, in response to determining that the control information is not detected from the predetermined radio signal.
