Abstract

A terminal includes a receiving unit that receives P-Max that is configuration information of maximum transmit power in a cell in Frequency Range 2 (FR2) among Frequency Range 1 (FR1) and the FR2; and a control unit that performs, when the P-Max of the cell in the FR2 is not supported, an operation of ignoring the P-Max of the cell in the FR2 or an operation of considering the cell in the FR2 as a barred cell.

Claims (19)

1. A terminal comprising:

a receiver that receives configuration information for maximum transmit power of a cell in a Frequency Range 2 (FR2) among a Frequency Range 1 (FR1) and the FR2, wherein the FR1 is a first frequency band and the FR2 is a second frequency band; and

a processor that ignores the configuration information of the cell in the FR2,

wherein, when the processor ignores the configuration information of the cell in the FR2, the processor configures, as the maximum transmit power in the cell in the FR2, maximum transmit power for the FR2 that is defined for each Power class.

2. The terminal according to claim 1 , wherein the configuration information is included in at least one of System Information Block2 (SIB2), System Information Block4 (SIB4), or FrequencyInfoUL-SIB in System Information Block 1 (SIB1).

3. The terminal according to claim 1 , wherein, when the processor ignores the configuration information of the cell in the FR2, the processor configures, as the maximum transmit power in the cell in the FR2, maximum transmit power for the FR2 that is defined for each Power class.

4. The terminal according to claim 1 , wherein, when the configuration information of the cell in the FR2 is not supported, the processor ignores the configuration information of the cell in the FR2.

5. A communication method executed by a terminal, the communication method comprising:

receiving configuration information for maximum transmit power of a cell in a Frequency Range 2 (FR2) among a Frequency Range 1 (FR1) and the FR2, wherein the FR1 is a first frequency band and the FR2 is a second frequency band; and

ignoring the configuration information of the cell in the FR2,

wherein, when the terminal ignores the configuration information of the cell in the FR2, the terminal configures, as the maximum transmit power in the cell in the FR2, maximum transmit power for the FR2 that is defined for each Power class.

6. A radio communication system comprising:

a terminal; and

a base station,

wherein the terminal includes

a receiver that receives configuration information for maximum transmit power of a cell in a Frequency Range 2 (FR2) among a Frequency Range 1 (FR1) and the FR2, wherein the FRI is a first frequency band and the FR2 is a second frequency band; and

a processor that ignores the configuration information of the cell in the FR2,

wherein, when the processor ignores the configuration information of the cell in the FR2, the processor configures, as the maximum transmit power in the cell in the FR2, maximum transmit power for the FR2 that is defined for each Power class, and

wherein the base station includes a transmitter that transmits the configuration information.
