## Abstract

There is disclosed user equipment including a communication unit for executing carrier aggregation and for executing communication through a plurality of carriers, and an antenna pictogram display unit for displaying, through an antenna pictogram, at least whether communication is allowed. When execution of the carrier aggregation is allowed, the antenna pictogram display unit displays an indication that the execution of the carrier aggregation is allowed together with at least one antenna pictogram.

## Claims

### Claim 1

User equipment comprising:
a processor configured to implement a communication unit that executes communication through a plurality of carriers by executing carrier aggregation, CA, including a primary cell, P-cell, and one or more secondary cells, S-cell; and
an antenna pictogram display unit configured to display, through an antenna pictogram, at least whether communication is allowed,
wherein, in response to detecting, by a report from a base station, that the S-cell is established, the established S-cell is activated, or scheduling of the activated S-cell is enabled, the antenna-pictogram display unit is configured to start displaying an indication that the CA is allowed together with at least one antenna pictogram.

### Claim 2 (depends on 1)

The user equipment according to claim 1, wherein the processor is further configured to implement a quality measurement unit that measures reception quality for each of a plurality of cells for which the CA is allowed,
wherein, when the CA is allowed, the antenna pictogram display unit is configured to display, for each of the plurality of cells, the antenna pictogram and a reception level.

### Claim 3 (depends on 1)

The user equipment according to claim 1,
wherein, when the CA is allowed, the antenna pictogram display unit is configured to display the one antenna pictogram and a number of carriers with which the CA is allowed.

### Claim 4

An antenna pictogram display method that is to be executed by user equipment configured to execute communication through a plurality of carriers by executing carrier aggregation, CA, including a primary cell, P-cell, and one or more secondary cells, S-cell, the method comprising:
a step to start displaying, in response to detecting, by a report from a base station, that the S-cell is established, the established S-cell is activated, or scheduling of the activated S-cell is enabled, an indication that the CA is allowed together with at least one antenna pictogram.
